PURPOSE: Frailty is a condition of weakness that includes an enhanced hazards of drawback and disability in elderly people. It is featured by reduced physical fitness, and also recognized as reduced psycho·physiological and immunological functions. Therefore, we need to develop more efficient methods to detect frailty and also needs to prevent and treat frailty.
METHODS: PubMed database was searched from January to April 2019 using predefined search terms “elderly and frailty”, “elderly and exercise”. Based on reference search, 89 articles were identified whereas 40 papers (22 references) met the inclusion criteria and were well connected with frailty and exercise. We analyzed the connections between exercise and frailty with many variables, and dealt with frailty-prevention exercise programs in the main text.
RESULTS & CONCLUSIONS: With aging, decreased skeletal muscle power, malnutrition, feeling of loneliness, fall, and osteoporosis were identified with an important factors to frailty. Among these, osteoporosis and related frailty fractures are a serious health problem in the elderly frailty. Osteoporosis is the most prevalent and major bone disorder, which is featured by progressive bone weakening and an increased risk of frailty fractures especially in the frail elderly. And also, physiotherapy can play a vital role in the management and intervention following frailty fractures. Osteoanabolic exercise (aerobic, resistance, and combined) also recommended to prevent, management and treatment of bone mineral density of osteoporotic females and frail elderly. More studies are urgently needed to determine which mode and duration exercises were best suited and effective for frail elderly.

INTRODUCTION: Many athletes use nutritional supplements for their performance enhancements and training effects. However, it is unclear that some of the dietary supplements have favorable outcomes, and others may increase the risk of doping or side effects.
METHODS: In this review, we discuss the Australian Institute of Sport (AIS) Sports Supplement Framework's Group A performance supplements regarding safety, legality, and effectiveness in improving sports performance. Group A supplements include caffeine, beta-alanine, bicarbonate, beetroot juice, creatine, and glycerol.
RESULTS: We found the use of these performance supplements could help athletes improve strength and endurance. However, the effects vary with individual athletes and depend on sports characteristics, training content, physical condition, and habits.
CONCLUSIONS: Therefore, a case-by-case approach is warranted to ensure their desirable effects. It is important to consult a doctor or sports nutritionist before consuming theses supplements and to monitor the individual's response through simulation.

PURPOSE: The purpose of this study was to provide a scientific basis for physiological recovery of cooling tubing intervention during simulated match in elite male wrestlers.
METHODS: Fourteen national wrestler were divided Cooling Tubing Group (CTG, n=7) and Non Cooling Group (NCG, n=7). The simulated match was conducted at 3 minutes 1 round, 1 minute rest, 3 minutes 2 rounds, and was performed according to each weight class. At the end of the match, CTG cooled the face, chest, elbow, and thigh by cooling mask, vest, and tubing, and then took a rest. NCG took a rest without any special treatment. To compare and analyze the changes of the two groups, measured the variables at rest, immediately after the simulation, 10 minutes, and 30 minutes.
RESULTS: There was no interaction effect between CTG and NCG intervention. However, the skin temperature (p<.001), the chest skin temperature (p<.01), the RPE (p<.001), blood lactate (p<.001), and heart rate (p<.001) was a significant difference between the time of measurements, in each group. In addition, CTG showed no significant difference compared to NCG, but most of the variables (HR, RPE, skin temperature, DHEA, and cortisol) showed a tendency to show effects.
CONCLUSIONS: In conclusion, there was no significant difference between the groups. However, CTG showed a decrease in skin temperature, RPE, and fatigue-related hormone compared with NCG, confirmed the possibility that cooling-tubing treatment could have a positive effect on fatigue recovery.

PURPOSE: Arterial stiffness is associated with cardiovascular events and mortality. Regular physical activity contributes to decrease in arterial stiffness. The purpose of this study was to analyze the relationship between physical activity level, as objectively assessed by a 3-axial accelerometer, and central artery stiffness in young female adults.
METHODS: Twenty-six young adults without overt clinical disease participated in this cross-sectional study. Physical activity level was assessed during three consecutive weekdays using ActiGraph wGT3X-BT accelerometer. Study participants were divided into either higher or lower activity group based on physical activity quantity and physical activity time with moderate to vigorous intensity (MVPA). Central artery stiffness was assessed by aortic pulse wave velocity (aortic PWV), augmentation index (AIx) and augmentation index adjusted at 75 beats per minute of heart rate (AIx@75) using SphygmoCor Xcel System.
RESULTS: AIx and AIx@75 were lower in the group with higher physical activity quantity (counts/min) compared with the group with lower physical activity quantity (p<.05). AIx was inversely associated with vector magnitude (r=-.412, p=.036) and AIx@75 was inversely related to axis-1 counts (r=-.421, p=.032), vector magnitude (r=-.466, p=.016), step counts (r=-.499, p=.021). Regarding MVPA, there were no significant group differences on central artery stiffness measures. However light-intensity physical activity time (r=-.398, p=.044) and MVPA time (r=-.403, p=.041) were negatively associated with AIx@75.
CONCLUSIONS: Augmented physical activity level is associated with reduced central artery stiffness in healthy young women.

PURPOSE: This study investigated the effects of Taekwondo training of foot angle application on Pelvic stabilization and trunk tilt.
METHODS: This study investigated the effects of Taekwondo training of foot angle application on pelvic stabilization and trunk tilt. 80 boys aged 11 to 13 years old were selected, then reselect 20 people of exercis group and 20 people of control group from Taekwondo trainees of elementary school who have length difference to their legs and trunk tilt called R-body type (right leg is long) group. Taekwondo Training of foot angle application was conducted once for 60 minutes, three times a week for 12 weeks.
RESULTS: After 12 weeks of training, In the trunk tilt, exercis group's neck tilt, spine tilt, pelvis tilt differences between front and back and leg tilt left were significantly decreased. In the pelvic X-ray examinations, exercise group's ilium height, difference between right and left ilium width, length difference between right and left obturator foramen height, length difference between right and left sacrum width were significantly decreased. In the correlation between trunk tilt and X-ray examination, there was positive correlation between neck tilt and obturator foramen width. Also there was positive correlation among spine tilt and ilium height, sacrum width. There was positive correlation between pelvic tilt and length difference between right and left ilium width. And there was positive correlation between length difference between right and left legs and length difference between right and left ilium width, obturator foramen width.
CONCLUSIONS: Taekwondo training has been shown to stabilize the pelvis through strengthening muscles that support the lower limb and spine, improve leg length and leg inclination, and correct the trunk slope through human body compensation.

PURPOSE: The purpose of this study was to determine the effects of treadmill gait training according to obstacle crossing on the hip, knee and ankle joint motion during gait cycle in patients with post stroke hemiplegia.
METHODS: Twenty-one patients with post stroke hemiplegia were divided into 3 groups as treadmill gait training with obstacle crossing group (TOG, n=7), treadmill gait training without obstacle crossing group (TGG, n=7) and control group (CON, n=7). TOG and TGG were performed treadmill gait training with and without obstacle crossing for 20 minutes, three times a week, and for 8 weeks. Hip, knee and ankle joint motion were measured before and after treadmill gait training. Statistical analyses was done using the ANCOVA and paired t-test.
RESULTS: Hip, knee and ankle joint motion were significantly increased in TOG and TGG after 8 weeks compared to before (p<.05, respectively). Hip, Knee and ankle joint motion were significantly increased in TOG compared with CON and TGG (p<.05, respectively).
CONCLUSIONS: TOG was more effective than both TGG and CON in order to improve hip, knee and ankle joint motion in hemiplegia patients. Especially, treadmill gait training with obstacle crossing significantly improved to improve lower limb joint movement during the gait cycle.

PURPOSE: The purpose of this research was to investigate the effects of gender and number of rescuers on the quality of cardiopulmonary resuscitation (CPR).
METHODS: Fifty-five university students (23 males vs. 32 females) participated in this study voluntarily. Each subjects performed one rescuer CPR and two rescuer CPR for 5-cycles in random order. The quality of CPR was recorded using a Resusci Anne Skillreporter manikin.
RESULTS: Male participants presented higher compression depth and correct compression than females. Two rescuer CPR had higher compression depth and correct compression than one rescuer CPR, but the two rescuer CPR had lower hands off time and compression fatigue. There was a significant gender by number of rescuers interaction for a compression rate. The two rescuer CPR had higher numbers of ventilation, but lower ventilation fatigue compared with the one rescuer CPR. There was a significant correlation between compression fatigue and compression depth of female subjects.
CONCLUSIONS: These results suggest that laypersons are taught to perform two rescuer CPR to provide high quality CPR. To increase the number of people trained in CPR, CPR educational program should be included in an undergraduate curriculum.

PURPOSE: Impaired autophagy, a conserved process for the cellular energy homeostasis by degrading damaged cytosolic constituents, is an important contributor to the pathogenesis of atherosclerosis. The purpose of this study was to determine whether regular aerobic exercise can improve obesity-induced dysregulation of autophagy in mice arterial endothelial cells.
METHODS: High-fat diet-induced obese mice were subjected to the treadmill running for 10 weeks (15 m/min, 1 hour/day, 6 days/ week). Endothelial cells were isolated from aorta by perfusing with QIAzol reagent. The mRNA and protein expressions of autophagy-related genes were investigated by qRT-PCR and western-blot respectively. Statistical analysis was performed by one-way ANOVA.
RESULTS: Autophagy-related gene expressions in both levels of mRNA and protein were significantly decreased in vascular endothelial cells and arterial vessels of obese mice. However, these phenomena have been partly reversed by the regular treatment of treadmill exercise for 10 weeks. Furthermore, eNOS downregulation induced by the obesity was also improved by the regular aerobic exercise, representing enhanced endothelial function.
CONCLUSIONS: The current study has shown that the obesity-induced autophagy dysregulation and vascular dysfunction can be partly improved by the regular aerobic exercise in mice vascular endothelial cells.

PURPOSE: Benign prostatic hyperplasia (BPH) is a typical male adult disease in which the prostate is enlarged but not cancerous. Autophagy is a catabolic process of cellular constituents and a mechanism for cellular homeostasis of tissues. Currently, it is not established whether BPH is linked to autophagy or not and whether endurance exercise training, an autophagy activator, can ameliorate its disease symptoms. Therefore, the purpose of this study was to investigate whether BPH is closely related with autophagy dysregulation and induced autophagy by exercise training can relieve BPH.
METHODS: Forty-eight male wild-type SD rats (10-week old) were randomly divided into 4 groups: Sham, BPH-sedentary, BPH-exercise, and BPH-finasteride. For BPD induction, rats were castrated and testosterone (3 mg/kg/day) were administered daily for 2 months. During this period, rats performed five daily bouts of 25-minute treadmill running exercise per week or daily treated with finasteride dissolved in corn oil (10 mg/kg) by oral gavage for 8 weeks. Prostate weight, autophagy flux, serum and prostate levels of androgens and inflammatory factors were analyzed. The results were analyzed with one-way ANOVA.
RESULTS: In BPH rats, the ratio of prostate weight/body weight was significantly elevated, but autophagy flux was significantly decreased (p<.05). Eight-week exercise training failed to reduce the ratio and to increase autophagy flux in the prostate of BPH rats. However, 8-week running training significantly decreased the levels of DHT and proinflammatory factors (IL-1β and IL-6) in the serum and the prostate of BPH rats (p<.05).
CONCLUSIONS: This current study suggests that endurance exercise training may be beneficial for BPH not through the mechanisms involved in autophagy regulation but through alleviating hormonal and inflammatory factors.

PURPOSE: The purpose of this study was to investigate the differences in physiological, metabolic, and hormonal responses after 65% of repetition maximum (RM) in males and females.
METHODS: Males (n=8, 20.0±2.1 years) and Females (n=8, ages 18.5-0.8 years) participated in a resistance session. The resistance exercise (RE) session included 3 sets of seven exercises, 10 repetitions at 65% 1RM intensity with 105 seconds rest periods. Serum free fatty acids (FFA), glucose, growth hormone (GH), estradiol (E), testosterone (T), cortisol (C) and capillary lactate concentrations were measured pre-exercise, post-exercise, 30 minutes, and 60 minutes into recovery. Respiratory variables (EPOC and RER) were also measured after RE session every 5 minutes until 60 minutes.
RESULTS: The relative strength (strength/muscle mass) of the upper body was significantly higher in males than in female (75.3% of male), lower leg strength (89.1% of male) did not show any difference between sex. There were no sex differences in GH, T, C, and E hormone responses including FFA and glucose except lactate (interaction effect, p=.020) after resistance exercise. Only GH increased significantly in both sexes immediately after RE.
CONCLUSIONS: These results indicate that an acute bout of RE session included 3 sets of seven exercises, 10 repetitions at 65% 1RM intensity with 105 seconds rest periods can stimulate the metabolism (FFA, glucose and lactate) and GH excluding sex hormones (T and E) including C. On the other hand, there may be sex difference in the lactate response to RE.
