A concussion is a major concern across the athletic population. Pre-vention of concussions can lead to a decrease of 3.8 million concus-sions that occur annually in the United States. Vision training, increas-ing neck musculature strength and quick reaction times are thought to be ways to prevent concussions. The purpose of this study is to review the literature on vision training, neck musculature, and reaction time, and how these interventions can prevent concussions. Upon review of the literature, vision training is proven to prevent concussions in a col-legiate football setting, but there is no literature on different levels or sports. There are inconclusive results on whether neck musculature strength prevents concussions. There are substantial results conclud-ing reaction time does prevent concussions by allowing the athlete to protect and anticipate head impact lessening the severity of the blow to the head. More research needs to be done for all three interventions to prove across all ages and levels of every sport that vision training, neck musculature strength, and reaction time prevent concussions in an ath-letic population. If proven true, practitioners in an athletic setting can use vision training, increasing neck musculature strength, and increas-ing reaction time as interventions to help prevent concussions in an athletic population.

Epilepsy is characterized by recurrent seizures and loss of neurons with abnormal rhythmic firing in the brains. In the present study, we investi-gated the effect of treadmill exercise on memory function in relation with cell proliferation and apoptosis in the hippocampus using pilocar-pine-induced seizure rats. Epilepsy was initiated by intraperitoneal in-jection of pilocarpine hydrochloride. The rats in the exercise group were forced to run on a motorized treadmill for 30 min once a day for 2 weeks. In the present results, treadmill exercise alleviated short-term and spatial learning memory impairments in the epileptic rats. Treadmill exercise suppressed neuronal degeneration and enhanced neuronal maturation in the epileptic rats. Treadmill exercise suppressed cell pro-liferation and apoptosis in the epileptic rats. Treadmill exercise alleviat-ed pilocarpine-induced memory impairments and suppressed neuronal loss in the hippocampus through down-regulation of apoptosis. These findings offer a possibility that treadmill exercise may provide a preven-tive or therapeutic value to the epilepsy-induced learning and memory impairments.

Stress is the physiological responses of organisms to harmful or threat-ening stimuli that allow appropriate behavioral responses to the stress-or. In the present study, the effect of treadmill exercise on stress-in-duced anxiety was evaluated using rats. To induce stress, the rats were exposed to an inescapable electric foot shock. Exposure of rats to the electric foot shock was performed for 7 days. The rats in the exercise groups were made to run on a motorized treadmill for 30 min once a day for 4 weeks stating one day after last electric food shock. Anxiety-like behaviors were determined by open field test and elevated plus-maze test. The expressions of c-Fos and neuronal nitric oxide synthase (nNOS) in the hypothalamus and locus coeruleus were detected by im-munohistochemistry. In the present results, locomotor activity in the center of the open field test and the number of entries and time in the open arms of the elevated plus-maze test were reduced in the rats with stress-induced anxiety. Treadmill running enhanced these locomotor activities, the number of entries and time in the stress-induced anxiety rats. c-Fos and nNOS expressions in the hypothalamus and locus coe-ruleus were increased in the stress-induced rats. Treadmill exercise re-duced c-Fos and nNOS overexpressions in the stress-induced rats. In the present study, treadmill exercise ameliorated anxiety-like behaviors in the stress-induced rats. The improving effect of treadmill exercise on anxiety-like behaviors might be ascribed to the suppressing effect of exercise on c-Fos and nNOS expressions.

The government has collaborated with the Health Promotion Board in coming out a bountiful of initiatives for the citizens to engage in exer-cise. Despite the initiatives, the obesity rate in middle-aged women is still high. This study seeks to understand and identify the vast barriers that prevent middle-aged women from exercising. Purposive sampling and semi-structured interview were conducted for the participants. The analysis of the interview revealed the significance of barriers in three areas: Priority of Family and Work Commitments, Minimal Promotion of Subsidized Initiatives by the Government, and Discrimination through the Usage of Language. It highlights that racial barriers are minimal and better time management would be appropriate to engage a healthier lifestyle. The study suggested female Singaporeans to incorporate sports in the lifestyle, more aggressive promotion of subsidized initia-tives and the use of common languages (English) in the exercise class.

This study aims to identify the relation between students’ participation in sports club activities and personality and sympathy based on the findings obtained from personalty and sympathy study and understand what the interrelational characteristics are. This study investigated a total of 408 individuals (male, 58.3%; female, 41.7%) who have continu-ously participated in sports club activity in middle schools located at Seoul and Gyeonggi province, Korea. To look at the type of event that they selected, 127 individuals (31.1%) reported that “School sports club event is already defined in school.” and 281 (68.9%) reported that “We can select among several school sports club events.” The events that they participated in are that 79 individuals participated in basket ball, 47 in line dancing, 96 in badminton, 2 in yoga, 31 in football, 129 in ping-pong, and 20 in floorball. In conclusion adolescence is a period that ad-olescents are physically and mentally developed in terms of personality, morality, creativity, and sociality. During this period, learning and experi-ence are very important for lifetime. Therefore, teenagers’ school sports club activity can contribute to fostering positive and desirable personal-ity and stabilizing emotional empathy among student participants. This study identified the relation between personality and empathy in ado-lescents, which was not studied before. As presented in previous re-searches, it can be found that positive personality can be cultivated by teenagers’ communal activities in school life. The link to connect this with empathy factor is considered to be the very communal activity, sports.

The present study aimed to comparatively analyze the effects of the whole-body vibration exercise health promotion program on the agility, the quick reaction ability, and the flexibility of the test-takers. Total 30 test-takers had been prepared for the practical test as the subjects. They were divided into the three groups: the practical college entrance examination group with whole-body vibration exercise, the practical college entrance examination group, and the control group. The mea-surements of each item were made before and after the program appli-cations of the side steps, the standing long jump, the standing high jump, the sitting trunk flexion, and the trunk forward flexion for 60 min 3 times a week. The side steps showed the significant differences among the groups. Although the standing long jump did not show any significant differences among the groups, the standing high jump showed the significant differences among the groups. Although the sit-ting trunk flexion showed the significant differences among the groups, the trunk forward flexion did not show any significant differences among the groups. But, the practical college entrance examination pro-gram group which carried out the whole-body vibration exercise at the same time showed the highest average value compared to the other groups. It was proven that, to the test-takers who had been preparing for the preparing examination for applying to a physical education-affili-ated department, the whole-body vibration exercise program is helpful to the promotion of the health, including the agility, the quick reaction ability, the flexibility, etc.

This study was conducted to compare muscular strength and balance of athletes with visual and hearing impairment. The study was carried out with 20 athletes of national Olympic level sports goalball team and 20 athletes of national Olympic level sports hearing-impaired karate team. Isokinetic muscular strength was assessed by IsoMed 2000 de-vice as concentric-concentric at 60°/sec and 240°/sec. Balance as-sessment was carried out with the Human Body Equilibrium 360 device. There was no significant difference between groups regarding age, height, weight and body mass index (P>0.05). There were no differenc-es between the dominant and nondominant knee flexion and extension peak torque (PT), % of flexion/extension PT ratio, % of dominant/non-dominant PT differences at 60°/sec and 240°/sec velocities (P>0.05). There was no difference between the groups regarding of both leg static balance (P>0.05). However, single leg standing balance was sig-nificantly different between groups in favor of athletes with hearing im-pairment (P<0.001). As a result of our study it was determined that muscular strength and static balance of athletes with visual and hear-ing impairment were similar, but athletes with visual problems are likely to have lower levels of single leg balance. Strategies to promote single leg balance in athletes with visual impairments are warranted.

Postural changes induce changes in chest wall kinematics and eventu-ally pulmonary function, and affect chest wall shape and chest motion. This study aimed to examine the effects of postural change on changes in the chest wall during respiratory muscle training. Using a repeated measures design, this study followed 13 healthy adults (13 men; mean age, 23.73 years). All participants performed four postures (neutral, full trunk rotation, half-range trunk rotation, and lateral ribcage shift pos-tures) during respiratory muscle training. The chest wall movement during the four postures was measured using a three-dimensional mo-tion-analysis system during respiratory muscle training. Surface elec-tromyography data were collected from the diaphragm and sternoclei-domastoid muscles, and the asymmetric ratio of muscle activation was calculated based on the collected data. The chest wall movements of the upper costal and middle costal region were greater in the neutral posture than in the full rotation, half rotation, and lateral ribcage shift postures (P<0.05). The respiratory muscle activation on diaphragm of left was greater in the full rotation posture than in the neutral posture, half rotation, and lateral ribcage shift postures (P<0.05). The asymmet-ric ratio of muscle activation was greater in the full rotation posture than in the neutral posture, half rotation, and lateral ribcage shift pos-tures (P<0.05). This study verified that postural change during respira-tory muscle training may affect chest wall movement and muscle acti-vation. Thus, this study recommends respiratory muscle training to be performed in neutral posture.

There was lack of study which evaluated the effects of characteristics of subjects such as the body mass index (BMI) or waist circumference (WC), as well as sexual differences on trunk muscle activities. The pur-pose of the present study was to compare the abdominal muscle activi-ties among the groups dividing criterion as the BMI, WC, and the gen-der. As a criterion of BMI and WC, subjects were arranged to three groups. Female subjects who were less than 25 kg/m2 BMI, and less than 90 WC were arranged as female with underweight group (FU), male subjects who were greater than 25 kg/m2 BMI and greater than 85 WC were arranged as male with overweight group (MO), male subjects who were less than 25 kg/m2 BMI and less than 85 WC were arranged in male with underweight group (MU). Surface electromyography re-sponses of the rectus abdominis, internal oblique, external oblique muscles and lumbar level of erector spinae were obtained during the plank and maximal voluntary isometric contraction (MVIC). The MO group showed significantly higher %MVIC value of the internal oblique and lumbar level of erector spinae, compared to the MU group (P<0.05). The %MVIC of the rectus abdominis was significantly greater with the FU group (P<0.05). There were significant differences in the root mean squared (RMS) values from MVIC among the three groups (P<0.05). Regardless of muscles differences, the MO group showed significantly lower RMS activity values than the FU and the MU groups (P<0.05). Present study indicates some considerations of interpreting surface electromyography (sEMG) signal from region overlapping large fat tis-sue especially for trunk muscles. Individual characteristics such as gender, BMI, and WC could affect the sEMG signals. The female and male with overweight represent relatively high %MVICs during exer-cise, but it might be due to relatively low RMS values from procedure of MVICs.

Personality trait of an athlete is a significant factor in sports injury reha-bilitation. The aim of the present study is to investigate whether there are differences in personality traits between male and female, profes-sional and amateur athletes from sports representing two ends of ex-treme to traditional namely; drag racing and archery. Overall 189 male and female, professional and amateur drag racers (n=144) and archers (n=45) took part in this study. Participants completed the personality traits of extroversion and neuroticism as measured by Eysenck’s classic Personality Inventory dimensions and thrill and adventure seeking (TAS), experience seeking (ES), disinhibition (DIS), boredom susceptibil-ity (BS), and sensation seeking (SS) as measured by Zuckerman’s Sen-sation Seeking Scale. The results showed that professionals scored significantly lower on neuroticism compared to amateurs. Drag racers scored significantly higher on TAS, DIS, and SS compared to archers and there were gender differences amongst archers on TAS and SS with males scoring higher than females. Such differences in personality factors and the readiness to take risks, lack of caution, and adventurous spirit can influence the risk of injury in athletes and indeed may influ-ence the outcome of rehabilitation. Practitioners would need to recog-nise difference in personality traits associated with the type of sport and the choice of interventions strategies.

The purpose of this study was to investigate the effects of different weight reduction methods on the body composition characteristics, cardiopulmonary functions, and health promotion of elite bodybuilding athletes in a comprehensive manner. For this purpose, the study ana-lyzed the effects of two different weight reduction methods on 25 elite bodybuilding athletes registered at the Bodybuilding Association over a period of 6 weeks. There were interactive effects on macronutrients, macrominerals, and antioxidants according to weight reduction meth-ods as the experiment group (6%±2%) maintained a certain amount of food intakes across various nutrients including energy intakes or made a slow decrease it, whereas the traditional group (16%±4%) made a sharp decrease in it due to relatively greater weight reduction than the experiment group and thus showed pattern differences from it. As for immunity variables, there was an increase to certain cytokines despite the traditional high weight reduction method, but it caused no exces-sive reduction of immunity or rapid decrease to certain factors of body composition. In addition, there were no significant differences in main and interactive effects on the one-repetition maximum of bench press and squat, which are two functional indicators of health promotion. These findings imply that the low weight reduction method within the range of 6%±2% minimized or maintained changes to muscle circum-ference or mass while causing no improvement to muscular strength.

The purpose of this study was to evaluate the effects of N-acetylcyste-ine (NAC) supplementation on cellular damage and oxidative stress in-dicators in volleyball athletes. Twenty male volleyball athletes at nation-al level performed a physical training session and were divided into 2 groups, which for 7 days took the placebo substance or NAC. After 7 days the athletes repeated the same training session. In both sessions, blood samples were collected 30 min before and immediately after the training session to measure cellular damage and oxidative stress mark-ers. The main results show that, although higher concentrations of glu-tathione peroxidase and superoxide dismutase were observed in post-session 1 than those in postsession 2, the other markers showed an in-crease in antioxidant action after supplementation of NAC, once the ef-fect of experimental conditions (P=0.030) were observed in: time effect (P<0.001) and interaction (P=0.019) for total glutathione; time effect (P<0.001) and interaction (P<0.001) for reduced glutathione; and time effect (P<0.001) for ferric-reducing antioxidant potential. The oxidant action indicated by the protein carbonyl was higher in the placebo group than in the NAC group (P=0.028), but a time effect (P<0.001) for the thiobarbituric acid reactive substances showed lower values in presession 1 than in presession 2. For the cellular damage markers, an-tagonistic results between markers were found. Based in the results, the supplementation of NAC during a short period was effective in re-ducing oxidant action and increasing antioxidant action. However, con-clusive alterations in the responses of the cellular damage markers were not obtained.

This study is intended to analyze differences in the self-rated health of patients according to the characteristics of hospitalized cancer pa-tients. To this end, this study analyzed the differences in self-rated health according to cancer diagnosis type, cancer stage and adjunctive treatment and analyzed the recognition of difficulties in physical activi-ties during hospitalization. A questionnaire survey was conducted among data of 162 hospitalized cancer patients. For the self-rated health of cancer patients according to diagnosis type, it was lower in the gastric cancer group than in the thyroid cancer group and the breast cancer group. For self-rated health according to cancer stage, it was higher in the order of the stage 3 group, stage 2 group and stage 1 group. For the self-rated health of patients receiving adjunctive treat-ment, it was the lowest in the chemotherapy+radiotherapy group. And for personal constraints according to cancer stage in the category of “physical,” it was higher in the stage 3 group than in the stage 1 group. For hospital environment restrictions according to cancer stage in the category of “tool,” it was higher in the stage 1 group than in the stage 3 group. In conclusion, personal constraints on the physical activities of cancer patients appear to be due to fatigue and a lack of motivation, but medical services that influence motivation are critical to individual and continued care strategies for the patients.

This study evaluated combined cognitive-motor program based on Al-exander technique and Bartenieff fundamental method for mild cogni-tive impairment (MCI) patients. The purpose was to explore the field ap-plication of combined cognitive-motor learning program centering on proprioceptive neuromuscular facilitation, developing sensory-motor coordination and enhancing focused attention to one’s whole body. Two practice methods were applied to the 40 MCI elder. The combined cognitive-motor learning program (CM) was applied to the 20 MCI elder while 20 elder took traditional movement learning program (TM). Mini Mental States Examination-Korea (MMSE-K), Time Up & Go Test (TUG), Flexibility Test and Pegboard Test were measured and analyzed. The collected data were analyzed by paired t-test. The results were as fol-lows: Both groups showed similar learning effect in Flexibility Test and Pegboard Test. However, in MMSE-K and TUG, CM group showed sig-nificant learning effect than TM group. Our data suggested body awareness and body consciousness through Alexander technique and Bartenieff fundamental program facilitated patients’ kinaesthesia: sen-sory awareness and conscious control of the whole movement. From these results, we conclude that combined cognitive-motor learning program is valuable as alternative program for cognitive development as well as physical development of MCI elder.

The purpose of this study was to investigate the effects of progressive treadmill cognitive dual-task training on gait performance in individuals with chronic stroke patients. Twenty-six participants with chronic hemi-paresis were recruited to this study and randomly distributed into two groups: progressive treadmill cognitive dual-task gait training (PTCDG group, 13 patients), conventional treadmill gait training (CTG group, 13 patients). All patients underwent 20 sessions of treadmill gait training with a harness (5 times per week, for a total of 4 weeks). The GAITRite was used to analyze gait kinematics, and 10-m walking test (10MWT) wear used as the clinical evaluation indicators. After training, PTCDG group showed significant improvement in gait velocity, cadence, single support time, and 10MWT compared to the control group. However there was no significant difference between the groups in the stride lengths in the affected and unaffected sides. The study verified that progressive treadmill cognitive dual-task gait training had a positive in-fluence on the gait and clinical gait index in chronic stroke patients.

The purpose of this study was to determine the effects of a 12-week walking exercise using a mobile device on cardiopulmonary function, metabolic risk factors, and self-efficacy in obese middle-aged women. For this study, 14 middle-aged subjects with obesity were included and performed walking exercise of 50%–60% maximum oxygen uptake in-tensity 3 times a week for 12 weeks. As a result, weight, % body fat, body mass index, and waist circumference significantly reduced. In ad-dition, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and hemoglobin A1c significantly reduced, while high-density lipoprotein cholesterol and flexibility significantly increased. Further-more, exercise using a mobile device significantly increased self-effica-cy. In conclusion, walking exercise using a mobile device is a good method to constantly increase the exercise participation rate, as it im-proves metabolic risk factor and obesity index, and increases self-effi-cacy.

This study aimed to examine and analyze the relationship between the physical activity of cancer patients during the hospitalization and the change in exercise recognition and restrictions on physical activity in depth. In this study, adult cancer patients aged more than 20 years re-siding in the metropolitan area (such as Seoul, Gyeonggi, and Incheon) were selected as a population, and 194 cancer patients from five gen-eral hospitals located in metropolitan area were selected as subjects by the purposive sampling. The relative importance for the effect on the physical restriction was greater in the order of the time spent in seden-tary activities and exercise positive recognition. The relative importance for cognitive psychological restriction was greater in the order of nega-tive exercise recognition, positive exercise recognition, the time spent in sedentary activities, the time spent in ordinary daily activities and the time spent in intentional movement. In the hospital environment restric-tion, the facility had a statistically significant effect on the movement and positive exercise recognition. But, socio-cultural restrictions were not affected by positive exercise recognition. As a result of this study, it was found that the physical activity restrictions of the cancer patients may affect differently depending on the physical activity level, exercise experience, and exercise recognition, requiring the interpretation of the physical activity restrictions in various ways.

Chagas heart disease (CHD) leads to a progressive functional impairment. Field tests, as the 6-min walk test (6MWT) and the incremental shuttle walk test (ISWT), may be inexpensive approaches in the evaluation of functional capacity of these patients. The present study was addressed to compare the 6MWT and the ISWT measures, and to determine the accuracy of these tests in the identification of functional impairment in patients with CHD. Thirty-five patients with CHD (47.1± 8.2 years, NYHA I–III) were evaluated by echocardiography, cardiopulmonary exercise test (CPET), 6MWT, and ISWT. Correlations between the CPET (peak oxygen uptake [peak VO2] and the ratio between ventilation and the carbon dioxide production [VE/VCO2 slope]) and the field tests (walking distances) were also performed. The receiver operating characteristic (ROC) curve was selected to identify the best distances related to identify those patients with functional impairment. There was no difference between distances walked during the 6MWT and ISWT (P= 0.694). The Bland-Altman analysis showed good agreement between the field tests. Both 6MWT and ISWT correlated with peak VO2 (r= 0.577, P< 0.001 and r= 0.587, P< 0.001, respectively) and ISWT correlated with VE/VCO2 slope (r= -0.339, P= 0.003). The cutoff distances of 6MWT and ISWT to identify patients with peak VO2 less than 20 mL/kg/ min were 520 m and 400 m, respectively, with no difference between the areas under ROC curves (P= 0.276). Both the 6MWT and the ISWT demonstrated accuracy in identify functional impairment in patients with CHD, being useful tools for the risk stratification of these patients.

This pilot randomized clinical trial assessed the feasibility of implement-ing motor control exercise (MCE) and patient education (PE) program for the management of chronic low back pain (CLBP) in a low resource rural Nigerian community. Thirty patients with CLBP were recruited and randomly assigned to MCE, PE, or MCE plus PE groups. The MCE pro-gram was provided twice a week while the PE program was provided once a week all for 6 weeks. Feasibility was assessed through recruit-ment rate, treatment compliance, retention/dropout rate, report of ad-verse events, perceived helpfulness, overall satisfaction, and clinical outcome of pain (numeric pain rating scale) and functional disability (Oswestry Disability Index). Many patients were willing to participate in the study and the recruitment rate was 77%. Treatment compliance in all the three groups were >65% for supervised treatment sessions and <50% for prescribed home program. Retention rate was high and greater overall satisfaction with the interventions was reported. Com-pared with the baseline, all the three groups improved significantly in pain and disability (P<0.05) after 6 weeks. Pairwise comparison re-vealed that the MCE plus PE group was superior to the PE group for pain and to the MCE for disability (P<0.05), with large effect size. It was concluded that the designed interventions are promising and conduct-ing a full-scale randomized clinical trial in the future is feasible to con-firm the effectiveness of the interventions for the management CLBP in rural Nigeria.

A 43-year-old male, office worker with history of chronic radicular low back pain radiating into the left leg was admitted to a sports medicine research center, neuroscience institute. During the past year, he visited a physiotherapist and orthopedic experts. Magnetic resonance imaging revealed a protruded disc at L4–5 level. Additionally, electromyography indicated that there was bilateral moderate irritation at the L5–S1 root. We designed a management package including exercise therapy, dry needling, and nonfunctional electrical stimulation for four sessions. Outcomes included pain intensity, pain with lumbar flexion, with the nu-merical rating scale (NRS), visual analogue scale (VAS), and function measured with the Oswestry Disability Index before and after the inter-vention. After 4 treatment sessions, the patient reported a reduction in pain intensity from a 9 to 2 on the NRS and from 90 to 30 on the VAS. In addition, the patient was able to perform lumbar flexion fully without pain.

The purpose of this study is to investigate the risk factors of metabolic syndrome, cardiorespiratory fitness, knee isokinetic function, and os-teoarthritis index inpatients with knee osteoarthritis women. Subjects were divided into the exercise group (n=9, aged 60.89±5.06), and the control groups (n=8, aged 61.25±1.91). Aquatic exercise was performed for 12 weeks, 3 times a week, 60 min a day. The changes of metabolic syndrome risk factors, cardiorespiratory fitness, knee isokinetic func-tion, and WOMAC index (Western Ontario and McMaster University osteoarthritis index) were measured and analyzed at pre- and postex-ercise program for verifying exercise effectiveness. As a result, fasting blood glucose (P<0.05), glycosylated hemoglobin (P<0.01), and tri-glyceride (P<0.05) were significantly decreased in the risk factors of metabolic syndrome. The maximum oxygen uptake in cardiorespiratory fitness was not significantly different. The left and right extensor mus-cles of knee isokinetic function increased significantly (P<0.01, P<0.01, respectively). There was no significant difference in flexor muscles. Os-teoarthritis index was significantly improved in stiffness (P<0.01) and physical function (P<0.05). In conclusion, aquatic exercise can be re-garded as an effective exercise program for managing metabolic syn-drome risk factors, increasing muscle function, and improving osteoar-thritis index in patients with osteoarthritis of the knee.

Participation in physical activities benefits individuals with disabilities in terms of addressing their social and psychological needs in order for the purposes of quality living. This study reports the findings from a case study conducted with a boy who has Duchenne muscular dystro-phy (DMD) in a swimming pool located in the campus of a private uni-versity in North Cyprus. The current study reports the adjustments made in the swimming pool in accordance with the needs of the partic-ipant, how service quality was increased to cater for these needs and in what ways the participant benefited from the aquatic program. This qualitative investigation aims to shed light onto how aquatic therapy has affected the boy with DMD physically, psychologically, and socially from the parents’ perspectives. The results revealed that aquatic thera-py had beneficial effects on the participant with DMD in terms of social-ization, relaxation, quality of life and self-perception.

To investigate whether whole body vibration (WBV) training increases the explosive force of the knee extensors in chronic kidney disease (CKD) patients. Fourteen CKD patients undergoing hemodialysis were random-ly allocated in WBV training or Sham group. Explosive force parameters (contractile impulse [CImp] and relative rate of force development [RFDr]) obtained in early (30 and 50 msec) and late phases (100 and 200 msec) of the knee extensors force/time curve. CImp and RFDr obtained at the early phase of force/time curve reduced after the intervention period, with a smaller decline for WBV (CImp at 50 msec [~-15% and -51%, P=0.038], RFDr at 30 msec [~-22% and -52%, P=0.044] and RFDr at 50 msec [~-11% and -54%; P=0.008]). In the late phase there was a lower decline for WBV group compared to Sham group, respectively: CImp: 100 msec (~-8% and -55%, P=0.025), 200 msec (~-3% and -46%, P= 0.025); RFDr 100 msec (~0.01% and -56%, P=0.033), 200 msec (~-5% and -36%, P=0.004). Three months of WBV training may attenuate the ex-plosive force reduction in CKD patients.

This study evaluated the effects of aerobic exercise program on the cardiovascular parameters, body composition, and quality of life (QoL) of people living with human immune virus (HIV). Patients were recruited from the HIV clinic in a tertiary hospital in Nigeria. Fish bowl method was used to randomize the patients to either experimental or control group. Experimental group received nutritional counseling and aerobic exercise program on a treadmill, 3 times a week for a period of 6 weeks, while the control group received only nutritional counseling. Cardiovas-cular parameters, aerobic fitness, body composition parameters, and QoL were evaluated at baseline and 6 weeks. Descriptive statistics was used to explore demographic data while the hypothesis was tested us-ing inferential statistics of t-test. Alpha level was set at P<0.05. The re-sult showed that there was an improvement in cardiovascular parame-ters in both groups, attaining significance in the experimental group (P=0.000). Aerobic fitness increased significantly in experimental group (P=0.000). Body composition decreased significantly while there was a significant difference in the muscle mass (%) between groups (P<0.05). All domains of QoL had a significant improvement in both groups (P<0.005). A 6-week aerobic exercise program in addition to nutritional counseling was able to significantly improve cardiovascular fitness, body composition, and QoL in people living with HIV/acquired immune deficiency syndrome. Nutritional counseling alone can bring about an improvement only in QoL parameters.
