Children need to participate in structured physical activities to avoid obesity and to engage in sports and games in the future. However, cer-tain groups of our population have little access to enhance levels of physical activity. One such group is children from low-income families who are more likely to have less opportunity for participation in physical activity because of factors such as unsafe streets or limited access to playgrounds. According to the United States Department of Health and Human Services, there is a strong relationship between family income and physical activity with low- income families being the most seden-tary. In order to design effective physical activity interventions for those children, there is a need to identify factors influencing physical activity in these populations, yet, there has been limited research that explores this issue. Therefore, the purpose of this article was to review the litera-ture on factors limiting physical activity among low-income children.

Brain development is a complex process, and stimuli during this devel-opment period may modulate the functional maturation of the brain. It has been shown that environmental stimuli, such as physical activity habits, have a beneficial effect on brain development. Endurance exer-cise and prolonged fasting state are known to improve brain function including cognition. The exact mechanisms of exercise improving brain function are still unknown. However, it can be considered that energy restriction and stressful challenge induced by long-lasting physical ex-ercise might cause direct effect on brain function. Upregulation of brain-derived neurotrophic factor and ketone body caused by exercise might be considered as the mechanism of exercise on brain function. In the present study, we discussed on two main topics: “exercise and BDNF” and “exercise and energy restriction.”

The present study aimed to empirically determine the relationship be-tween the degree of exercise participation by the elderly people and their euphoria. The analysis results are as follows. First, the difference between the elderly people’s participation in the exercises and the eu-phoria that they have experienced showed that in all low variables of euphoria, the group who participated in the exercises showed a higher level of euphoria than the group who did not participate in the exercis-es. Second, the analysis of the effects of the elderly people’s motiva-tions for exercise participation on euphoria showed that there was a significant relation between the two. Furthermore, the following sug-gestions were made for areas that the current study did not cover, as well as for the follow-up studies. The follow-up studies would need an in-depth multiangled analysis of various fun factors in order to encour-age the elderly people to participate in the exercises by conducting in-terviews and observation studies with the study participants.

To compare the effects of 6 weeks of long or short high-intensity interval training (long- or short-HIIT) on body composition, hunger perception, food intake and rating of perceived exertion (RPE). Twenty previously untrained women (25±5 years) were randomly assigned to do a long-HIIT (n=10) or a short-HIIT (n=10). The long-HIIT group performed fif-teen 1-min bouts at 90% of maximum heart rate (HRmax), interspersed by 30-sec active recovery (60% HRmax). The short-HIIT group per-formed forty-five 20-sec bouts at 90% of HRmax, interspersed by 10-sec active recovery (60% HRmax). The training for both groups was con-ducted 3 times a week for 6 weeks. All subjects performed the Astrand cycle ergometer test to estimate maximal oxygen consumption (VO2max) 1 week before and after the training period, as well as body composition, which was estimated through circumferences and skinfold thicknesses. For all training sessions, the heart rate, visual scale of hunger, internal load, and RPE were recorded. In the first and last week of training, sub-jects were asked to record a 24-hr food diary for 3 days. Both training in-duced significant pre to post decreases for fat mass, fat percentage, waist circumference, sum of seven skinfolds and RPE. As expected esti-mated, the VO2max increased in both groups. There were no differences for hunger perception, energy intake, and body mass. Long and short-HIIT resulted in fat loss, without altering the energy intake.

The purpose of this study was to investigate the effects of 16 weeks of spinning and bicycling exercises on body composition, physical fitness and blood variables in female adolescents. Subjects participated in this study were 24 female middle school students (12 spinning cycles, 12 general bicycles) attending to Seoul Yeoksam middle school. Each group was trained for 16 weeks, 3 times a week, and 1 hr per day after school. Body composition, physical fitness (1,200 running, sit-ups, back strength, sit and reach, side-steps) and blood variables (low-density li-poprotein cholesterol, glucose, reactive oxygen species, and malondi-aldehyde) were examined before and after 16 weeks of training. As the results, body weight did not show any significant difference; however, body mass index, and % body fat were significantly difference in spin-ning group. The enhancement in physical fitness factors were recog-nized in both groups, which was greater in spinning group in sit-ups, back strength, and side steps. Blood parameters were significantly dif-ference between groups, but between group and time interactions were significantly difference in glucose and reactive oxygen species. In conclusion, this study suggests that 16 weeks of bicycle exercises were positive changes in body composition, physical fitness and blood con-stituents, indicating that spinning cycle is more beneficial as compared to ordinary bicycle.

This study examined and compared, based on year of study and gender, the health and performance indices of university undergraduate students. Eighty-nine students (mean± standard deviation age, 22.47± 2.22 years) were randomly selected for assessment prior to second semester examination of 2015/2016 academic year. body mass index, resting metabolic rate, visceral fat, skeletal muscle mass, body fat, systolic & diastolic blood pressure, resting heart rate, upper & lower body endurance, handgrip strength, and lower back and hamstring flexibility were assessed. The students had sedentary heart rate, low skeletal muscle mass, average upper and lower body endurance, and weak handgrip strength. Significant difference existed in the visceral fat (P= 0.008) between third and fourth year students. There were significant gender differences in resting metabolic rate (P= 0.000), skeletal muscle mass (P= 0.000), body fat (P= 0.000), systolic blood pressure (P= 0.001), heart rate (P= 0.005) and handgrip strength (P= 0.000). There are gender differences in association between health and performance indices. Dependable health education and pragmatic involvement of undergraduate university students in structured exercise programmes are recommended.

This study investigated the correlation between the neck disability index (NDI) and visual analogue scale (VAS), which are indicators of neck pain, shoulder joint range of motion (ROM), and muscle strength in women with a slight forward head posture. This study was carried out on 42 female college students attending Uiduk University in Gyeongju, Korea. The neck pain and disability index for each subject was mea-sured using VAS and NDI, respectively. Two physiotherapists measured the shoulder joint ROM and muscle strengths of the subjects using a goniometer and a dynamometer, respectively. External rotation, internal rotation, and abduction of the shoulder joint were measured for each subject. A significant negative correlation between neck pain and shoulder joint ROM in external rotation and the muscle strength of the shoulder joint in abduction was found in the subjects. In addition, a sig-nificant positive correlation was observed between ROM in external ro-tation and muscle strength in abduction. This study showed a significant negative correlation between neck pain and ROM in external rotation as well as between neck pain and the muscle strength in abduction.

The proprioceptive neuromuscular facilitation (PNF) sets up a feature of treatment developed with the objective to facilitate and improve the motor performance. The aim of this study was to investigate in healthy female individuals the effects of electrophysiological of a diagonal of the PNF upper limb. The sample consisted of 30 female participants aged between 18 to 28 years, randomly divided into 3 groups (G1, G2, and G3). The three groups had 2 moments of electroencephalographic signal detection, before and after the task. The statistical neurophysio-logical design allowed the analysis of the relative power of alpha band in three leads (Fz, F7, and F8). Thus, a three-way mixed factorial analysis of variance (ANOVA) was performed to investigate the factor inter sub-jects (groups) and intrasubjects (areas and moments), a two-way ANO-VA to investigate the interactions between the three factors, and a one-way ANOVA to analyze separately the factors time and area. A P≤0.05 was considered as significance level. The results showed significant increase of alpha band in the three groups analyzed, being more evi-dent to the G2 group. Therefore, the PNF can be considered favorable also in relation to the cortical behavior, reinforcing its use in rehabilita-tion processes, especially in the clinical practice of physiotherapy.

The purpose of this study was to evaluate the components of walking adults who have no symptoms by integrating the temporal and spatial walking variables obtained from the GAITRite system. The following de-scribes previous debates on weight-loaded walking training. The con-clusion was as follows. First, there was a significant difference in walk-ing distance between the 0% group and 1% group and between the 1% group and 2% group (P<0.05). Sencond, there was a significant differ-ence in walking velocity between the 0% group and 1% group and be-tween the 0% group and 2% group (P<0.05). Third, there was a signifi-cant difference in walking cadence between the 0% group and 1% group, between the 1% group and 2% group, and between the 0% group and 2% group (P<0.05). These study results indicate that diverse amounts of weight loading can be effective for enhancing the walking factors of adults without symptoms.

This exploratory study evaluated motor cognition program for improving temporal-spatial timing memory ability with mild cognitive impairment (MCI) patients. The purpose was to explore the efficacies of motor cog-nition program according to practice methods, centering on coordina-tion and observation pattern. Two practice methods were applied to the 40 MCI elder. In experiment 1, participants divided into two group as, one-hand practice group (n=20) and both-hands practice group (n=20). In experiment 2, participants divided into two group as, active observa-tion group (n=20) and passive observation group (n=20).The partici-pant was asked to alternatively press two buttons 6 times with the index finger hand with goal rhythm pattern (3,600 msec in total duration). In coordination pattern, bimanual practice was more effective for improv-ing temporal-spatial timing memory ability than unilateral practice. In observation pattern, active observation showed better learning effect than passive observation. However, there was a learning effect even in passive observation pattern. Such a result claimed for the elderly, who has problem to do daily activity, could use observation of temporal-spa-tial timing task for improving cognitive ability.

Whey protein is a nutritional supplement commonly ingested for recov-ery following exercise. However, the timing when whey protein supple-ment must be ingested after muscle-damaging exercise is debatable. Therefore, the present study investigated the effects of the timing of supplement ingestion on muscle damage markers after eccentric or muscle-damaging exercise. In total, 32 collegiate male students partici-pated in this study; they were randomly assigned to control group (n=8), before supplement group (n=8), after supplement group (n=8), or be-fore and after supplement group (n=8). Eccentric exercise was per-formed using elbow flexors with a modified preacher curl machine. Subsequently, maximal isometric strength, muscle soreness, range of motion (relaxed and flexed arm angle), and blood markers (creatine ki-nase and aspartate transaminase) were measured before and after ex-ercise. Repeated-measure analysis of variance was used to analyze the effects of timing of supplement. No significant group by time effects were noted in maximal isometric strength, muscle soreness, range of motion, and blood markers (P>0.05). The timing of whey protein supple-ment did not affect reduction of muscle damage or recovery following eccentric exercise.

The purpose of this study was to identify the instability of the trunk and the pelvis of subjects who were standing on differently angled ramps under conditions in which the ramps were crossed. Changes in the trunk and the pelvis while each subject was standing on one leg in the direction of the cross ramps at four angles (0°, 5°, 10°, and 15°) were measured. To identify instability, the trunk inclination, trunk imbalance, pelvic position, pelvic rotation, and pelvic torsion of 20 healthy male subjects were measured. The measurement was conducted using a three-dimensional spinal diagnostic imaging system (Back Mapper). According to the results of the measurement, trunk imbalance, pelvic position, pelvic rotation, and pelvic torsion differed between the medial and lateral ramps and with different ramp angles. This study’s results suggested that different mediolateral ramp conditions altered the pelvic and trunk alignment. With the 15° ramp, the anterior tilt and lateral tilt of the pelvis increased regardless of ramp direction. The 10° ramp condi-tion altered the pelvic rotation to the contralateral side. In addition, the lateral trunk tilt was elevated with the lateral down foot condition.

As recreational running continues to gain popularity, more individuals are seeking ways to improve running performance. RunSmart is a run-ning intervention program designed to enhance a runner’s form. In ad-dition to correcting flaws in a runner’s form, RunSmart offers the oppor-tunity for runners to continue a regular regimen while slowly integrating changes in form. The purpose of this case series was twofold: to deter-mine if the RunSmart program coincides with improvements in oxygen consumption (VO2), a variable often associated with better running per-formance times, and to evaluate the RunSmart program in regard to en-hancing gait biomechanics. Five recreational runners volunteered to participate in this program. Subjects initially reported to the clinic for an initial submaximal VO2 treadmill test and lower extremity biomechanical analysis. After the initial testing session, each subject attended one session of one-on-one individualized RunSmart instruction per week for 6 weeks. At the first RunSmart session, subjects received a biomechan-ical analysis to determine their foot strike pattern and areas of muscular weakness and range of motion limitations. Throughout the 6-week run-ning program, participants ran 5 days every week for predetermined times each day; 2 runs every week were designated as interval training runs. Subjects then underwent a follow-up submaximal VO2 treadmill test and lower extremity biomechanical analysis at the end of 6 weeks. Descriptive statistics were used to assess data pertaining to VO2 and biomechanical analysis and compare initial and follow-up testing ses-sions. Following completion of the RunSmart program, subjects demon-strated improvements in VO2 and also improved several biomechanical factors related to the lower extremity running gait. Based on the results from this case series, the RunSmart training program may have the po-tential to change a runner’s form and improve VO2, thus resulting in im-proved distance running times. However, this is speculation given the nonexperimental nature of this case series. Future research on this top-ic should include a greater number of participants in randomized con-trolled trials on injury prevention and running efficiency.

The present study aimed to examine the effects of a prior session of power training on blood pressure values during tasks that mimic the activities of daily living in hypertensive and normotensive older women. A randomized crossover experimental design was used for this study. Eleven older women (age, 66.1± 1.2 years; body mass index, 26.7± 4.8 kg/m²; systolic blood pressure, 133.9± 23.4 mmHg) were recruited to participate. Volunteers were randomly underwent to a single session of physical exercise equalized by training volume, characterized by 3 sets of 8–10 repetitions in 8 different exercises. However, Power training session was performed at a higher intensity (moderate) than Sham session (rest/very, very easy ). Immediately after the end of the exercise session, subjects were assigned to perform five tasks that mimic the activities of daily living. Hemodynamic parameters were recorded before and immediately after the session of physical exercise, as well as in the end of each of the tasks. Results demonstrated significant elevations in systolic blood pressure and pulse pressure values during the performance of the tasks after the Sham session. However, values were not altered in the power training session. Data of the present study indicate that an acute session of power training can maintain blood pressure values lower during the subsequent performance of tasks that mimic activities of daily living in older women.

Obesity and chronic pain are two major diseases of the 21th century. Our principal objective was to investigate the effects of a 4-week reha-bilitation program on adiponectin and leptin concentrations, and insulin resistance, in patients with abdominal obesity and chronic pain syn-drome. Our secondary objectives were to investigate the effects of this program on pain, body mass index (BMI), waist circumference and maximal oxygen consumption (VO2max) and to compare changes in VO2m-ax between patients with or without insulin resistance. Among a con-secutive sample of 128 patients with abdominal obesity hospitalized for rehabilitation for a chronic pain syndrome, 111 completed the protocol, which was a 4-week rehabilitation program including 6 hr of rehabilita-tion per day, 5 days per week, in a referral center of rehabilitation. This prospective cohort study compared clinical (BMI, waist circumference, VO2max, pain) and biological measures (concentrations of adiponectin, leptin and insulin, score of homeostasis model assessment of insulin resistance [HOMA]) before and after the program. Plasma leptin, adi-ponectin and insulin concentrations (P<0.0001) and score of HOMA (P=0.0002) had decreased significantly by the end of the 4 weeks. Pain, BMI and waist circumference decreased significantly, and VO2max im-proved significantly (P=0.0001). Patients with insulin resistance had less improvement of their aerobic condition at the end of the 4 weeks (P<0.002). The rehabilitation program decreases the concentration of leptin, and improves insulin sensitivity in patients with chronic pain and visceral obesity. Aerobic recovery was worse for patients with insulin resistance than other patients.

This study investigated the effects of a 4-week moderate intensity walk-ing exercise on the levels of C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), and adiponectin in overweight or obese individu-als. Twenty-seven (13 men and 14 women) physically inactive, over-weight or obese (body mass index>25.0 kg/m2) individuals participated in the study. Each participant was randomly assigned to either exercise (EX; n=15) or control (CON; n=12) group. The EX group performed mod-erate intensity walking exercise on a treadmill for 60 min at 70% of max-imal heart rate for 4 weeks (3 days/wk). Overnight fasting blood samples were collected before and after the study period (Pre and Post) to ana-lyze the levels of pro-/anti-inflammatory cytokines such as CRP, TNF-α, and adiponectin. CRP and adiponectin as well as body weight and body composition were not significantly altered following the 4-week exer-cise intervention. However, there was a significant group×time interac-tion for TNF-α. The post hoc test revealed that the level of TNF-α signifi-cantly decreased only in EX (EX: mean ±standard deviation, Pre 55.18±6.57 pg/mL, Post 50.31±6.22, P=0.018 vs. CON: Pre 55.5 ±5.88, Post 58.19±6.48, P=0.25). EX Post was also significantly lower as com-pared to CON Post (P=0.0074). Although there was no change in body weight or fat mass, the 4 -week aerobic exercise training was long enough to decrease the level of TNF-α, indicating physical activity may improve level of inflammation independently from the change in fat mass. The current study also confirmed previous research suggesting that longer period of exercise training accompanied by weight loss may be required to induce significant changes in CRP and adiponectin.

The aim of the present study was to compare three different forms of exercises namely lumbar stabilization, dynamic strengthening, and Pi-lates on chronic low back pain (LBP) in terms of pain, range of motion, core strength and function. In this study, 44 subjects suffering from non-specific LBP for more than 3 months were randomly allocated into the lumbar stabilization group, the dynamic strengthening group, and the Pilates group. Ten sessions of exercises for 3 weeks were prescribed along with interferential current and hot moist pack. Pain was assessed by visual analog scale, functional affection by modified Oswestry Dis-ability Questionnaire, range of motion by assessing lumbar flexion and extension by modified Schober test and core strength was assessed by pressure biofeedback on day 1 and day 10 of the treatment. There was reduction of pain, improvement in range of motion, functional ability and core strength in all the 3 exercise groups. The improvement was signifi-cantly greater in the lumbar stabilization group for all the outcome mea-sures, when compared the posttreatment after 10th session. Pairwise comparison showed that there was greater reduction of disability in the Pilates group than the dynamic strengthening group. It was concluded that the lumbar stabilization is more superior compared to the dynamic strengthening and Pilates in chronic nonspecific LBP. However, long-term benefits need to be assessed and compared with prospective fol-low-up studies.

The purpose of this study was to evaluate the effect of abdominal mus-cle strengthening training (AMST) using proprioceptive neuromuscular facilitation (PNF) on pulmonary function, pain, and functional disability index in chronic low back pain (CLBP) patients. Thirty CLBP patients were randomly assigned to the traditional physical therapy (control) group (n=15) and PNF-AMST group (n=15). Forced expiratory volume at 1 second (FEV1) was measured to measure changes in pulmonary function. To measure the degree of pain, a visual analog scale (VAS) was used. The Oswestry Disability Index (ODI) was used to assess the disability level due to low back pain. A paired t-test was performed to compare differences within the groups before and after intervention. An independent t-test was performed to compare differences between the test and control groups. The level of significance was set at α=0.05. Within-group changes in FEV1 were significantly different in the experi-mental group (P<0.01), and those in VAS and ODI were significantly dif-ferent in both groups (both P<0.01). The improvements in FEV1, VAS, and ODI were significantly greater in the experimental group than in the control group (P<0.01). This study showed that AMST using PNF was effective in enhancing pulmonary function and decreasing pain and functional disability index inpatients with CLBP. We expect it to be use-ful as one of the programs for CLBP patients in the future.

The aim of this study is to investigate whether single nucleotide poly-morphisms (SNPs) of zinc finger homeobox 3 (ZFHX3 ) gene are suscep-tibility to obesity. Recently, several study suggested that specific poly-morphisms in various genes may have effect to obesity. In present study, 54 SNPs of ZFHX3 gene were genotyped in 209 overweight and obese patients with a body mass index (BMI)≥23 kg/m2 (mean±stan-dard deviation, 44.7±6.4 kg/m2) and 159 healthy controls with a BMI of 18.5–23.0 kg/m2 (43.6±6.2 kg/m2). Genotyping of each SNP was per-formed by custom DNA chip. Logistic regression models (dominant, re-cessive, and log-additive models) were used to calculate odds ratio, 95% confidence interval, and P-values. Significant association was considered at P<0.05. Among tested SNPs in ZFHX3 genes, seven SNPs of ZFHX3 gene showed significant association with obesity (P<0.05 in each model, respectively). In conclusion, these results indi-cate that SNPs of ZFHX3 gene might be contributed to development of obesity in the Korean population.
