PURPOSE: Heart rate variability leads affective changes, which are associated with athletic performance. This study aimed to examine the relationship between heart rate variability, athletic flow, and shooting performance in wheelchair shooting athletes. 
METHODS: Eight male and female wheelchair shooting athletes were participated in the study. Heart rate variability was measured at rest and during shooting practice and competitions. Flow experience and shooting score were collected only during practice and actual shooting. SPSS Windows 25.0 was used to perform the following analysis. A repeated one-way ANOVA was applied to analyze the differences in heart rate variability at rest, during practice and actual shooting. In order to see the linear and curvilinear relationship among the variables, a hierarchical regression analysis was conducted.
RESULTS: The level of average heart rate and the ratio of Low Frequency (LF) to High Frequency (HF) of heart rate variability were significantly at different situations. At the resting period average heart rate was the highest while LF/HF was the lowest, which indicated that LF was less activated than HF at rest as compared to actual shooting. A hierarchical regression analysis showed that flow was a significant linear predictor for shooting performance.
CONCLUSIONS: Heart rate variability is changing depending on the circumstance that athletes faced to, which suggests that the changes may be associated with psychological states and performance.

Fish oil contains omega-3 fatty acids, such as eicosapentaenoic acid (EPA; 20:5 n-3) and docosahexaenoic acid (DHA; 22:6 n-3). Consumption of EPA and DHA has been expected to improve fatigue recovery, endurance performance, antioxidant production, and anti-inflammatory responses. Therefore, this review aimed to evaluate the effects of omega-3 fatty acid on endurance performance as evaluated by human and animal studies and summarizes its effects on cardiovascular and endothelial functions. 
METHODS: This review summarized the effects of EPA and DHA supplementation on the maximum oxygen uptake, exercise economy, muscle endurance performance, and cardiovascular and endothelial functions.
RESULTS: Effects of EPA and DHA supplementation on the maximum oxygen uptake are controversial. However, it has been suggested to improve the exercise economy and make the continuation of exercise easier. EPA and DHA supplementation could also improve endurance performance in the peripheral muscles. In addition, they may improve cardiovascular and vascular endothelial functions at rest and have positive effects on the heart rate, stroke volume, and cardiac output during a submaximal exercise.
CONCLUSIONS: This review concluded that EPA and DHA are considered effective in improving endurance performance in the peripheral muscles and cardiovascular function.

PURPOSE: Patellofemoral pain is a common overuse injury in knee joint among runners. McConell taping technique has been recommended to alleviate symptoms in patients with patellofemoral pain. However, the clinical effects of McConell taping are not well-described. Therefore, we reviewed the effect of McConell taping in reducing patellofemoral pain.
METHODS: In this review, we summarized the effect of McConell taping on pain management, muscular function, proprioception, and functional task performance.
RESULTS: Application of a standard McConell taping technique to patients with patellofemoral pain showed a positive effect on pain management. However, there are limited investigations about proprioceptive improvement after taping. In addition, there are controversial results on vastus medialis and vastus lateralis EMG activity and functional task performance.
CONCLUSIONS: Understanding effectiveness and mechanism of McConnell taping is important to provide evidence to clinical professionals. As we reviewed and summarized many different studies, controversial findings exist in scientific and clinical studies. Therefore, it is recommended that future investigations into McConnell taping should focus on these factors to provide more consistent effects so that many clinicians can use McConnell taping technique with evidence.

OBJECTIVE: This study examined the association between estimated cardiorespiratory fitness (eCRF) and mental health in Korean older adults. The present study was carried out using data from the 2008 Living Profiles of Older People Survey.
METHODS: A total of 13,333 participants aged 60 years and older (57% women) completed the assessments (i.e., socioeconomic status, health behaviors and conditions, and mental health status) and were included for the final analyses. eCRF was assessed with sex-specific algorithms and classified as lower (lowest 25%), middle (middle 50%), and upper (highest 25%) categories. Korean version of Mini-Mental State Examine and short-form Geriatric Depression Scale were used to assess depressive symptoms and impaired cognition, respectively. Logistic regression analyses were conducted to estimate the odds ratio (OR) and 95% confidence interval (CI) for depressive symptoms and impaired cognition according to eCRF categories.
RESULTS: In the total study samples, the risk of having depressive symptoms was 24% lower for the middle eCRF group (OR, 0.76; CI, 0.69-0.84) and 49% lower for the upper eCRF group (OR, 0.51; CI, 0.45-0.59) compared with the lower eCRF group (reference, OR=1) and remained statistically significant even after adjustments for all the covariates included in this study. The risk of having impaired cognition was 18% lower for the middle eCRF group (OR, 0.82; CI, 0.74-0.91) and 26% lower for the upper eCRF group (OR, 0.74; CI, 0.66-0.84) compared with the lower eCRF group (OR=1) and remained statistically even after adjustments for all the covariates. 
CONCLUSIONS: The current findings of the study suggest that eCRF may have an independent predictor of both depressive symptoms and impaired cognition in this Korean older adults, underscoring the importance of promoting physical fitness via regular exercise to maintain good mental health later in life.

PURPOSE: Reduced muscular strength is a key player in loss of physical function and quality of life in older adults. It has been reported that eccentric training has positive effects on the preservation of eccentric strength, produces less delayed onset muscle soreness, and has a lower metabolic cost for older individuals. Therefore, the present study investigated the effects of eccentric-based training on skeletal muscle strength and physical function in older adults.
METHODS: Sixteen healthy older subjects (over the age of 65) participated either in eccentric training group (ETG, n=8) or in conventional resistance training group (CTG, n=8) twice a week for eight weeks. The ETG group performed motorized eccentric training, and the CTG group performed a leg press using air pressure. Physical function and muscular strength assessments were performed before and after 8 weeks. The primary outcomes for physical function included gait speed, stair climbing, and the chair stand test, and the secondary outcomes included muscle strength and power.
RESULTS: The ETG group demonstrated significant improvements in physical function (gait speed and stair climbing) and muscle strength (isokinetic strength and power in knee tests) (p< .05) compared to the CTG group after 8 weeks. There were no significant differences for chair stand test (p >.05) after 8 weeks.
CONCLUSIONS: Motorized eccentric-based training was more effective in improving muscle strength and physical function in aged individuals than conventional resistance training, which s suggests that eccentric training is may be more beneficial for older individuals to improve overall physical function.

PURPOSE: Psychological factors have been identified as an important factor underlying physical activity behavior in adults. However, the extent to which these psychological factors impact physical activity behavior remains poorly understood. The aim of the study was to examine the association between psychological stress and physical inactivity in subsets of data from the Korean Genome and Epidemiology Study (KoGES).
METHODS: 69,219 participants (24,025 men) aged 40-69 were drawn from urban and rural community based cohort studies, which are subprojects of KoGES. We analyzed the association between psychological stress and physical inactivity using logistic regression. Cox's proportional hazard regression analysis was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) of exercise behavior changes according to psychological stress level changes.
RESULTS: Compared to the healthy stress group, the likelihood of physical inactivity was increased in high-risk stress group (men OR=1.88, 95% CI 1.63-2.17, p<.001, women OR=2.24 95% CI, 2.04-2.47, p<.001). During the mean follow-up period of 4.6 years, compared to the sustained healthy stress, the group with increased stress level was at a higher risk of remaining physical inactive (men HR=2.16, 95% CI 1.24-3.69, p<.001, women HR=1.54, 95% CI 1.12-4.06, p<.001), and the risk becoming physical inactive (men HR=2.33, 95% CI 1.33-4.09, p=.003, women HR=2.13, 95% CI 1.12-4.06, p=.021).
CONCLUSIONS: These results suggest that the psychological stress could be barrier of exercise participation. Management of psychological stress should be considered in the strategy for promoting exercise participation in the community.

PURPOSE: The purpose of this study was to investigate the effects of either aerobic exercise or resveratrol supplementation on mitochondrial biogenesis in skeletal muscle of the high fat diet-induced obese mice.
METHODS: C57BL/6 (4 weeks aged) male mice were divided into four groups; normal diet group (NC, n=10), high fat diet group (HC), high fat diet group with chrysin supplementation (HCh, n=10) and high fat diet with exercise group (HE, n=10). Aerobic exercise was performed on a treadmill exercise for 40-60 min/day at 10-14 m/min, 0% grade, 4 days/week for 16 weeks. Chrysin (50 mg/ kg body weight) daily administrated orally at 4 days/week frequency for 16 weeks.
RESULTS: The gene expression of SIRT-3 in HE group was significantly increased compared to that in HC group (p<.05). Also, PGC-1α and COX-IV mRNA levels in the HE group were the highest among all groups (p<.05).
CONCLUSIONS: It seems that high fat diet-induced obese dose not affect mitochondrial biogenesis gene expression in skeletal muscle. However aerobic exercise training could increase the mitochondrial biogenesis gene expression of skeletal muscle in high fat diet-induced obese mice. These findings suggest that only aerobic exercise not chrysin supplementation has a positive effect on mitochondrial biogenesis in the skeletal muscle in high fat diet-induced obese mice.

PURPOSE: The purpose of this study was to determine the effect of vastus lateralis muscle fascicle length on isokinetic muscle strength and dynamic balance in youth soccer players.
METHODS: Fourteen youth soccer players were divided into long fascicle length group (LFG, n=7) and short fascicle length group (SFG, n=7) by fascicle length of vastus lateralis muscle using ultrasound imaging. And measurements of muscle thickness, fascicle pennation angle, and physiological cross-sectional area were taken at the same location. Additionally, maximal isokinetic strength of knee extensors was assessed at 60°/sec and 120°/sec and a Y-balance test was completed.
RESULTS: Fascicle length and ratio of fascicle length/lower limb length were significantly greater in LFG than that in SFG (p<.001). Fascicle pennation angle (p<.01) and physiological cross-sectional area (p<.05) were significantly greater in SFG than that in LFG. The isokinetic maximal strength of knee extensors at 120°/sec was significantly greater in SFG than that in LFG (p<.05). The composite score of Y-balance was significantly greater in SFG than that in LFG (p<.05).
CONCLUSIONS: Our results show differences in architectural characteristics of the vastus lateralis. Further, the maximal isokinetic strength of knee

PURPOSE: The mechanisms underlying the protective effects of exercise training against cognitive decline are not fully understood. This study aimed to investigate the effects of treadmill running on oxidative stress and heat shock protein levels in a mouse model of early stage triple transgenic Alzheimer's disease (3xTg-AD).
METHODS: We divided 5-month old 3xTg-AD mice (N=20) into the control (AD+CON, n=10) and exercise training (AD+EX, n=10) groups. Background strain mice were included as wild-type controls (WT, n=10). AD+EX mice were subjected to treadmill running at a speed of 15 m/min, 50 min/day, 5 days/week for 12 weeks.
RESULTS: Treadmill running protected 3xTg-AD mice from cognitive decline and significantly suppressed the increase in soluble Aβ1-42 protein levels (AD+CON vs AD+EX, p=0.015) and the progression of oxidative damage. This was evidenced by significant increase in anti-oxidative protein levels such as superoxide dismutase-1 (SOD-1), heme oxygenase (HO-1) and heat shock protein 70 (HSP70) in the hippocampus of AD+EX mice compared to AD+CON mice. Moreover, the brain-derived neurotrophic factor (BDNF) and synaptic proteins such as PSD95 and synaptophysin were upregulated in AD+EX mice compared to AD+CON mice.
CONCLUSIONS: Our findings support and extend previous studies reporting the preventive effects of exercise training on the pathological processes of the Alzheimer's disease in the 3xTg AD mouse model.
