Physical activity is known as a preventative method for preventing life-style-related diseases. Smartphone applications for health and fitness intervention have released with rapid increase of innovative technolo-gy. Reviews of recent publications on mobile application have been conducted to observe feasibility and applicability for physical activity intervention. Bibliographic searches of PubMed and ScienceDirect were conducted with key terms, ‘physical activity,’ ‘fitness,’ ‘smart-phone,’ and ‘health’ between the years 2014 and 2017 to obtain 5,087 publications. Out of 5,087 articles, five articles on sensor-based applica-tions and five articles on user entry-based applications were obtained through the inclusion and exclusion processes. Accuracy of the physi-cal activity assessments were reported to be high in comparison to the conventional assessment tools. The overall subject rating on the app motivational ratings were positive with high correlation between physi-cal activity and treats and cues. The adherence rates to the apps sig-nificantly dropped prior to 3 months. Publications that elucidate feasibil-ity and accuracy of smartphone applications that motivates physical activity seem limited with adequately conducted study designs. Large-scaled, control-compared, long-term randomized control trials should be conducted to elucidate the effects of the app interventions.

This article reviews the mechanism and effects of instrument-assisted soft tissue mobilization (IASTM), along with guidelines for its practical application. IASTM refers to a technique that uses instruments to re-move scar tissues from injured soft tissues and facilitate healing pro-cess through formation of new extracellular matrix proteins such as collagen. Recently, frequent use of this instrument has increased in the fields of sports rehabilitation and athlete training. Some experimental studies and case reports have reported that IASTM can significantly improve soft tissue function and range of motion following sports injury, while also reducing pain. Based on the previous studies, it is thought that IASTM can help shorten the rehabilitation period and time to return to sports among athletes and ordinary people who have suffered sports injuries. However, few experimental studies of the mechanisms and ef-fects of IASTM have examined, while case reports have accounted for the majority of articles. In the future, the scientific basis of IASTM and its reliability should be provided through well-designed experimental studies on humans. Moreover, IASTM studies that have mostly focused on tendons need to broaden their scope toward other soft tissues such as muscles and ligaments.

Falls and fall related injuries become an emerging health problem among older adults. As a result a review of the recent evidences is needed to design a prevention strategy. The aim of this review was to determine the effect of square stepping exercise (SSE) for fall down in-jury among older adults compared with walking training or other exer-cises. An electronic database search for relevant randomized control trials published in English from 2005 to 2016 was conducted. Articles with outcome measures of functional reach, perceived health status, fear of fall were included. Quality of the included articles was rated us-ing Physiotherapy Evidence Database (PEDro) scale and the pooled ef-fect of SSE was obtained by Review Manager (RevMan5) software. Significant effect of SSE was detected over walking or no treatment to improve balance as well to prevent fear of fall and improve perceived health status. The results of this systematic review proposed that SSE significantly better than walking or no treatment to prevent fall, prevent fear of fall and improve perceived health status.

Parkinson disease is one of the common brain diseases caused by do-paminergic neuronal loss in the substantia nigra and dopaminergic fiber loss in the striatum. In the present study, the effects of treadmill exer-cise on motor performance, dopaminergic loss of neurons and fibers, and α-synuclein expression in the nigrostriatum were evaluated using rotenone-induced Parkinson rats. For the induction of Parkinson rats, 3-mg/kg rotenone was injected, once a day for 14 consecutive days. Treadmill running was conducted for 30 min once a day during 14 con-secutive days. Rota-rod test for motor balance and coordination and immunohistochemistry for tyrosine hydroxylase and α-synuclein in the nigrostriatum were performed. In the present study, motor balance and coordination was disturbed by induction of rotenone-induced Parkin-son disease, in contrast, treadmill exercise alleviated motor dysfunction in the rotenone-induced Parkinson rats. Nigrostriatal dopaminergic loss of neurons and fibers was occurred by induction of rotenone-induced Parkinson disease, in contrast, treadmill exercise alleviated nigrostriatal dopaminergic loss of neurons and fibers in the rotenone-induced Par-kinson rats. α-Synuclein expression in the nigrostriatum was enhanced by induction of rotenone-induced Parkinson disease, in contrast, tread-mill exercise suppressed α-synuclein expression in the rotenone-in-duced Parkinson rats. Treadmill exercise improved motor function through preservation of nigrostriatal dopaminergic neurons and fibers and suppression of nigrostriatal formation of Lewy bodies in rote-none-induced Parkinson rats.

The olfactory bulbectomy (OBX) is a well-known method inducing ani-mal model of depression. Depression is associated with dysfunction of serotonin (5-hydroxytryptamine, 5-HT) system. In the present study, an-tidepressive effect of treadmill exercise was investigated using olfacto-ry bulbectomized rats. After bilateral bulbectomy, the rats in the tread-mill exercise groups were subjected to run on a treadmill for 30 min once a day during 28 days. Increased immobility time and decreased fast time in the forced swim test were observed in the olfactory bulbec-tomized rats. Sucrose preference in the sucrose preference test was decreased and activity in the open field test was also increased in the olfactory bulbectomized rats. Treadmill exercise decreased immobility time and activity and increased fast time and sucrose preference in the olfactory bulbectomized rats. Expressions of 5-HT and tryptophan hy-droxylase (TPH) in the dorsal raphe of rats were suppressed by OBX and treadmill exercise increased the expressions of 5-HT and TPH in the olfactory bulbectomized rats. Serotonin receptor type 1A (5-HT1A) expression in the dorsal raphe was reduced by OBX and treadmill exer-cise increased 5-HT1A expression in the olfactory bulbectomized rats. In the present study, treadmill exercise ameliorated OBX-induced depres-sive symptoms. The antidepressive effect of treadmill exercise might be ascribed to the enhancement of serotonergic function through upregu-lation of 5-HT1A expression in the dorsal raphe.

Today sedentary lifestyles are a major public health concern and there are many evidences related to physical inactivity. The well-documented evidence is that regular physical activity is an essential part for improv-ing overall health with advancing aging and the most efficient means playing roles of rehabilitation and prehabilitation. However, there are few activity programs which could motivate older adults to continue and maintain their active lifestyles. The purpose of the current study was to describe experience of sport stacking which applied to Korean older adults in the first time. Eighteen older adults living in the community in Seoul which was the capital and largest metropolis of the Republic of Korea participated in the study. A qualitative interview and a survey were conducted and data were analyzed by interpretive content analysis. Indi-vidual, semistructured, face-to-face interviews were recorded, tran-scribed, condensed and coded to find themes. The main themes were identified regarding older adults’ experience of sport stacking: enjoyment of sport stacking, attitudes toward sport stacking as a physical activity program, and benefits from sport stacking. In conclusions, Korean older adults had positive experience of sport stacking and it was necessary for developing strategies to spread it as the physical activity program for older persons in Korea to improve their health and quality of life.

Mobile phone use while walking can cause dual-task interference and increases safety risks by increasing attentional and cognitive demands. While the interference effect on cognitive function has been examined extensively, how perception of the environment and walking dynamics are affected by mobile phone use while walking is not well understood. The amount of visual information loss and its consequent impact on dy-namic walking stability was examined in this study. Young adults (mean, 20.3 years) volunteered and walked on a treadmill while texting and at-tending to visual tasks simultaneously. Performance of visual task, field of regard loss, and margin of stability under dual-task conditions were compared with those of single-task conditions (i.e., visual task only). The results revealed that the size of visual field and visual acuity de-mand were varied across the visual task conditions. Approximately half of the visual cues provided during texting while walking were not per-ceived as compared to the visual task only condition. The field of regard loss also increased with increased dual-task cost of mobile phone use. Dynamic walking stability, however, showed no significant differences between the conditions. Taken together, the results demonstrate that the loss of situational awareness is unavoidable and occurs simultane-ously with decrements in concurrent task performance. The study indi-cates the importance of considering the nature of attentional resources for the studies in dual-task paradigm and may provide practical infor-mation to improve the safe use of mobile phones while walking.

The aim was to investigate the effect of a dietary supplementation on the repeated sprint ability (RSA) performance in recreationally trained team sports athletes. Twelve young men underwent a RSA exercise protocol in five trials, in which participants ingested carbohydrates (CHO) plus caffeine (Caf), CHO plus arginine (Arg), CHO plus branched-chain amino acids (BCAA), CHO plus Caf, Arg, and BCAA (ALL), and CHO only. Heart rate, oxygen saturation, hematic lactate, ratings of per-ceived exertion, average sprint time, total time, best sprint time, peak power, and average power were taken. Data revealed no significant ef-fects neither on physiological nor performance parameters with any of the supplements.

The objective of this study was to reveal characteristics of muscle strength of upper extremities of wheelchair (WC) basketball players and to ensure more-specific training program preparation. Isokinetic muscle strength of 12 WC basketball players were assessed by ISOMED 2000 device. The assessment protocol was evaluated at 60°/sec velocity with 5 times repeated force and at 240°/sec with 15 times repeated force. This protocol was carried out individually for shoulder flexion-extension and wrist flexion-extension movements at the right and left extremities. The flexion/extension ratio was determined to be outside of the ratios accepted as normal for primarily shoulder joint and for wrist joint. The extension movement was stronger than flexion movement in the shoul-ders at both velocities and the flexion movement was stronger than ex-tension movement in the wrist. The repeat times where the peak torque occurred were 2–3 repeats at 60°/sec velocity during flexion and exten-sion movements for the wrist and shoulders, and the peak torque oc-curred at an average of 5–6 repeats in the shoulders at 240°/sec veloci-ty and it occurred at 3–4 repeats in the wrist. The angles where the peak torque of the shoulder flexion and extension occurred varied be-tween 80°–115° at both velocities, and it varied between 5°–30° angles for the wrist. As this study revealed, determination of muscle strength characteristics of WC athletes and especially using objective isokinetic devices will guide the planning of the appropriate training and exercise programs and preventing sports injuries in long term.

The objective of this study was to examine the internal training load (TL), IgA, and salivary steroid hormone responses in elite youth judo athletes during an entire annual training periodization. Ten male judo athletes (18±2 years, 72.3±12.3 kg, and 175±6 cm) competing at a state/national level were examined for the TL and salivary imune-endocrine responses variations over an annual judo season, divided in three macrocyles com-posed by distinct periods denominated preparatory period (PP), compet-itive period (CP) and transition period (TP). At the end of PP and CP, sali-va samples were collected to determine cortisol, testosterone and IgA concentrations. Throughout PP and CP the session-rating of perceived exertion and the total duration of each session were monitored, allowing the internal TL and weekly training strain (TS) calculation. During all macrocycles, significant decreases in TL and TS were observed during CP compared with PP (P<0.05), although no significant differences were observed for immune-endocrine concentrations between PP and CP (P>0.05). Specific variations were observed comparing periods with similar characteristics throughout the macrocycles as higher TL and TS (PP1 to PP2 and PP3, P<0.05), increased testosterone (CP1 to CP3, P=0.024) and decreased testosterone-cortisol ratio (PP1 to PP2, P=0.005). The present findings suggest that the internal TL variations over an annual multipeak traditional periodization did not influence the resting mucosal immune-endocrinal responses in young judo athletes.

Inpatient cardiac rehabilitation (ICR) has been commonly conducted af-ter cardiac surgery in many countries, and has been reported a lots of results. However, until now, there is inadequacy of data on the status of ICR in Korea. This study described the current status of exercise thera-py in ICR that is performed after cardiac surgery in Korean hospitals. Questionnaires modified by previous studies were sent to the depart-ments of thoracic surgery of 10 hospitals in Korea. Nine replies (re-sponse rate 90%) were received. Eight nurses and one physiotherapist completed the questionnaire. Most of the education on wards after cardiac surgery was conducted by nurses. On postoperative day 1, four sites performed sitting on the edge of bed, sit to stand, up to chair, and walking in the ward. Only one site performed that exercise on postoper-ative day 2. One activity (stairs up and down) was performed on differ-ent days at only two sites. Patients received education preoperatively and predischarge for preventing complications and reducing muscle weakness through physical inactivity. The results of the study demon-strate that there are small variations in the general care provided by nurses after cardiac surgery. Based on the results of this research, we recommended that exercise therapy programs have to conduct by ex-ercise specialists like exercise physiologists or physiotherapists for pa-tients in hospitalization period.

The purpose of this study was to evaluate the effects of 12-week tread-mill-based (MT) and track-based (TT) walking program on maximal oxy-gen consumption (VO2max), muscular endurance, muscle strength, and ankle range of motion (ROM) in ankle sprain experienced young people. Twenty subjects (12 males, 8 females) volunteered to participate in this study and divided into two groups (MT and TT). All subjects completed MT and TT 4 times per week with each session of 60 min with 65% from maximum heart rate. Incremental test on treadmill and 20-m shuttle run test for endurance capacity (VO2max), 2-km walking test for muscular en-durance, vertical jump for strength, and ankle ROM for flexibility were analyzed before and after the training intervention. We found significant increase in incremental, 2-km walking and 20-m shuttle run after both MT and TT. Just after TT were significant increased vertical jump and ankle ROM. In conclusion, TT seems to induce a more positive effect on muscle strength in lower extremity and ankle ROM than treadmill-based walking training in ankle sprain experienced young people.

The purpose of this study was to investigate the impact of a communi-ty-based aquatic exercise program on physical performance among adults with mild to moderate intellectual disability (ID). Twenty-two community-dwelling adults with mild to moderate ID volunteered to participate in this study. Participants completed an 8-week aquatic ex-ercise program (2 days/wk, 1 hr/session). Measures of physical perfor-mance, which were assessed prior to and following the completion of the aquatic exercise program, included the timed-up-and-go test, 6-min walk test, 30-sec chair stand test, 10-m timed walk test, hand grip strength, and the static plank test. When comparing participants’ mea-sures of physical performance prior to and following the 8-week aquat-ic exercise program, improvements were seen in all measures, but the change in scores for the 6-min walk test, 30-sec chair stand test, and the static plank test achieved statistical significance (P<0.05). An 8-week group aquatic exercise program for adults with ID may promote improvements in endurance and balance/mobility.

The purpose of this study is to investigate the effect of resistance exer-cise on fitness, blood pressure, and blood lipid of hypertensive mid-dle-aged men. To achieve the goal of the study, a total of 23 subjects were selected. Among them, 14 subjects who exercised regularly were selected as the exercise group, while the remaining 9 subjects were selected as the control group. In terms of data processing, the IBM SPSS Statistics ver. 21.0 software was used to calculate the mean and standard deviation. Regarding the verification of difference on the change of means between the groups, analysis of covariance was used for statistical process. As a result, significant differences were found in cardiovascular endurance, muscle endurance, flexibility, and triglyceride. These results indicate that the resistance exercise only had slight effect on hypertensive middle-aged men.

The aim of this study was to determine the influence of expectations plus mobilization with movement (MWM) in kinesiophobia, perceived disability and sensorimotor variables in patients with lateral epicondyl-algia. A pilot randomized controlled trial in 24 patients with lateral epi-condylalgia was conducted. Perceived pain, pain-free grip strength, pressure pain detection threshold, kinesiophobia measured with the short version of Tampa Scale of Kinesiophobia, perceived disability of the upper limb measured with disability of the arm, hand and shoulder questionnaire, and perceived disability specifically for the elbow joint measured with patient-rating tennis elbow evaluation, and also satis-faction were assessed. Participants were randomized to receive writ-ten instructions in order to create positive expectations regarding the technique in one group (n=12) or neutral expectations in the other one (n=12). All patients were treated for three sessions with the MWM technique. Measures were recorded before and after treatment. The effect size was calculated by Rosenthal “r” for nonparametrical tests. There were no significant statistical differences (P>0.05) between groups after receiving the treatment for none of the physical analyzed variables. The Wilcoxon test showed statistically significant changes in kinesiophobia (Z=-2.278, r=0.47, P=0.023) and perceived disability (Z= -2.934, r=0.61, P=0.003) within positive expectations group. In conclu-sion this pilot study shows that a positive expectation almost given in a sealed envelope before treatment plus MWM produced changes in ki-nesiophobia and perceived disability in the immediate term, in patients with lateral epicondylalgia.

The aims of this study were to determine an effective knee function rehabilitation program for athletes undergoing partial medial meniscectomy. Participants were randomly assigned to neuromuscular training (NT) or strength training (ST) group and subjected to functional assessments before surgery and again at 4, and 8 weeks post hoc. Functional knee assessment, such as Lysholm knee scoring, star excursion balance, and BTE PrimusRS isokinetic performance tests were evaluated in each group. All postoperational symptoms were significantly improved after 4 and 8 weeks of NT and ST. Both NT and ST programs showed effective knee function recovery seen as an increase in muscular strength and endurance. However, the NT program showed the most significant functional improvement of dynamic balance and coordination.

The aim of this study was to analyze the relation between incline angle of whole body and kinematic variables at tripping during gait. The par-ticipants consisted of healthy adult female (n=6). The three- dimension-al (3D) motion analysis of posture restoring after inducing tripping of right foot at supporting phase of left foot was performed. As a result, supporting time elapsed of one stride and one foot at tripping showed longer than that of normal gait. The length of one stride showed longer at tripping than that of normal gait, and velocity of center of gravity (COG) showed faster at tripping than that of normal gait. Anteriorposte-rior incline angle of whole body showed more forwarded incline at trip-ping than that of normal gait. As a result of correlation among variables, one stride and supporting time elapsed showed positive relation r=0.973 (R2=0.947, P<0.001), also r=0.920 (R2=0.846, P<0.001) relative to velocity of COG, r=0.970 (R2=0.941, P<0.001) of 1-stride time elapsed relative to velocity of COG and r=0.833 (R2=0.613, P<0.05) of velocity of COG relative to anteriorposterior incline angle respectively. Therefore instantaneous stoppage of gait posture when tripped at supporting phase of one leg during gait may be impossible and rather may cause a recovery of gait pattern when secured the faster velocity of COG and the longer of supporting time elapsed of one leg.
