PURPOSE: To suggest future research directions and current research trends based on representative studies of existing exercises and the gut microbiome. In addition, we reviewed methodologies to study the relationship between exercise and the gut microbiome.
METHODS: The research methodologies and results were integrated through a literature review of the latest “exercise and gut microbiome” studies and a narrative review.
RESULTS: Although exercise is indirectly related to the gut microbiome or immunity, evidence for a direct effect is still lacking. However, with the recent discovery of gut microbiomes that can help improve exercise performance, it is clear that exercise can positively alter the gut microbiome.
CONCLUSIONS: Strong evidence suggests that regular moderate exercise improves overall immune function and lowers the incidence of inflammation-related disease. In addition, certain microorganisms affect exercise performance.

PURPOSE: The purpose of this study is to develop a scale to quantitatively evaluate the exercise instructor's teaching ability and to verify its validity and reliability.
METHODS: The participants were 331 students enrolled in the college of physical education. The survey was conducted using Google Forms. The questionnaire contained 36 questions, comprising seven questions on professionalism; eight on emotional communication ability; nine on fidelity; and, twelve on safety. A 5-point Likert scale was used. Factor analysis was performed, and Cronbach's alpha coefficient was calculated for the validity and reliability analyses of the research tool; additionally, correlation and multiple regression analyses were performed. All data were analyzed using the STATA 17.0 statistical program.
RESULTS: In the exercise instructor for older people evaluation questionnaire developed in this study, the Kaiser-Meyer-Olkin (KMO) value was 0.8 (0.88-0.93) for all factors, demonstrating its validity for factors including professionalism, emotional communication ability, fidelity, and safety. Cronbach alpha coefficient was 0.9031, indicating high reliability. A strong correlation exists between factors, and through regression analysis, age (.1874, p=.027), professionalism (.8049, p=.000), fidelity (.6009, p=.000). The adequacy of the evaluation questionnaire (1.8606, p=.000) had a statistically significant effect on safety.
CONCLUSIONS: This questionnaire can be used as a tool to improve the quality of the exercise instructors for older people and serve to recognize the appropriate instructional methods for prospective exercise instructors for older people.

PURPOSE: Postmenopausal status is associated with an age-related decline in hormones, abnormal appetite regulation, weight gain, and increased risk of cardiovascular disease (CVD). Exercise is a useful non-pharmacological intervention that improves the levels of hormones involved in appetite regulation and weight management while reducing CVD risk factors. The present study aimed to elucidate the effect of a ballet program on menopause-related changes in satiety or levels of appetite regulation hormones, including leptin and ghrelin, homeostatic model of assessing insulin resistance (HOMA-IR).
METHODS: The EX group performed the ballet program. In the fasting state, body composition; leptin, ghrelin, insulin, and glucose levels; and HOMA-IR values were assessed before and 12 weeks after the intervention.
RESULTS: A significant group by time interaction (p<.05) was noted for percentage body fat, leptin, insulin, and HOMA-IR, which significantly decreased (p<.05), and ghrelin, which significantly increased (p<.05). CONCLUSIONS: These results indicate that this ballet program may be an attractive and enjoyable intervention for improving menopause-associated appetite regulation hormone changes in postmenopausal women

PURPOSE: The purpose of this study is to verify the effect of soft tissue stiffness on joint range of motion and athletic performance in soccer players.
METHODS: Fifteen adult male soccer players participated in the study. After the warm-up, calf muscle and Achilles tendon stiffness were measured. Subsequently, range of motion of the ankle joint and 30 m sprint and vertical jump were performed. Exercise performance was assessed as a field test to create an experimental environment similar to that of actual training and competition.
RESULTS: Achilles tendon stiffness showed a significant correlation with the 30 m sprint and the vertical jump (p<.05). A moderate correlation was observed between the 30 m sprint and the vertical jump(p<.01). Soleus muscle stiffness was significantly correlated with the 30 m sprint(p<.05). No other correlations were observed.
CONCLUSIONS: Therefore, it was confirmed that Achilles tendon stiffness affects exercise performance. In a follow-up study, it was necessary to confirm the effect of the stiffness of various soft tissues on exercise performance.

PURPOSE: This study was conducted with racket athletes at a university to determine the effect of combination of resistance exercise and black maca for four weeks on strength and endurance of trunk muscles and fatigue-related biomarkers.
METHODS: There were 16 university racket athletes classified into two groups: CO (control) (n=8) and RE (resistance exercise) (n=8). Body composition and muscle function were tested before the experiment (baseline), after four weeks (racket), and after ten weeks (racket+black maca). Before measuring body composition, we collected a blood sample to measure fatigue-related biomarkers such as myoglobin, creatine kinase (CK), lactic acid, and ammonia. Black maca was purchased from Essoco.
RESULTS: In both the CO and RE groups, racket+black maca lowered blood ammonia levels compared to that at the baseline (p<.05) and racket (p<.001). There were no differences in the other fatigue-related factors. In the muscle function test, the racket+black maca increased the extension and flexion strength compared to that at the baseline (p<.05), while only extension strength increased after racket (p<.05) in the RE group. In both groups, the racket+black maca increased the extension and flexion endurance compared to that at the baseline (p<.05).
CONCLUSIONS: Black maca intake effectively lowered the blood ammonia levels and improved muscle function. The effect on muscle function enhanced significantly when combined with resistance exercises. These results suggest that combination of black maca and resistance exercise may help improve exercise performance.

PURPOSE: PURPOSE: This study aimed to examine the relationship between performance-related factors and physical abilities in Korean national bobsled and skeleton athletes.
METHODS: Sixteen bobsled and skeleton athletes who participated in the 2018 Pyeongchang Winter Olympics as a Korean national team volunteered to participate in this study. The participants were evaluated in terms of performance-related factors, including anaerobic power, 5 bound jump (5 BJ), and sprinting speed by sections, and physical abilities, including isokinetic strength, 1 repetition maximum (1 RM) strength, body composition, anthropometry, and agility. Stepwise selection of multiple regression analyses was used to investigate the relationship between performance-related factors and physical ability.
RESULTS: Statistically significant correlations were observed between anaerobic power, sprinting speed by sections, 5 BJ and chest, isokinetic strength (knee, 180°/s), deadlift, and side-step.
CONCLUSIONS: The results of this study show that the performance of Korean national bobsled and skeletal athletes is related to upper and lower body strength and agility. Thus, future training programs for bobsled and skeletal athletes should focus on improving strength and agility for performance enhancement.

PURPOSE: This study investigated whether physical activity (PA) and cardiorespiratory fitness (CRF) modulate the relationship between eating speed and metabolic syndrome (MetS) in Korean university students.
METHODS: A total of 1,071 college students 751 males and 320 females participated in this study. The volume of PA (minutes per week) assessed by a self-reported questionnaire was classified as sufficient or insufficient based on the global recommendation of 150 minutes per week. Self-reported eating speed was classified as normal or fast. CRF was classified as low (lowest 25%), moderate (middle 50%), and high (highest 25%) based on the maximum volume of oxygen consumption determined during a graded treadmill running.
RESULTS: Bivariate logistic regression analysis showed that the adjusted odds ratio (OR) of fast eating for metabolic syndrome was 1.94 (95% confidence interval, CI=1.34-2.82, p<.001) in the total group and 1.75 (95% CI=1.18-2.59, p=.005) in male students only. Logistic regression showed that in the total group, fasting eating was associated with an increased risk of MetS (OR=1.780, 95% CI=1.223-2.259, p=.003) compared to individuals with normal eating speed (OR=1) even after adjustments for age, sex, smoking, and alcohol intake. Additionally, male students with fast eating were at increased risk of MetS (OR=1.750, 95% CI=1.181-2.529, p=.005) compared to their counterparts with normal eating speed even after adjustments for all the covariates. Moderation analyses by Andrew F. Hayes showed that the effect of eating speed on MetS risk differed by physical activity (β=-0.389, 95% CI=-0.706- 0.071, p=.017) and CRF levels (β=-0.307, 95% CI=-0.496-0.118, p=.002) even after adjustments for all the covariates.
CONCLUSIONS: The current findings of the study suggest that both regular PA and CRF can play a preventive role against MetS associated with fast eating in Korean college students.

PURPOSE: This study aimed to verify whether the degree of pain cognition by injury-experienced athletes in a sports setting varies depending on their emotional status, and to compare the values between the VAS (subjective pain score) and RIII reflex (objective pain data).
METHODS: Injured (n=15) and non-injured (n=15) experienced athletes participated in the experimental procedures with pain stimulation, RIII reflex, and VAS measurement, while emotional images (neutral, pleasure, and unpleasure) were randomly presented. The RIII reflex was measured simultaneously with TENS stimulation of the sural nerve while the OASIS images were presented, and the VAS was measured between the sets of images. Data were collected using electromyography (EMG) and VAS.
RESULTS: The relationship between the group and the VAS score according to the emotional state was significant (p=.028), and the relationship between the group and the RIII reflex depending on the emotional state was not significant (p=.344). Furthermore, the relationship of the group “emotion” measurement was not significant (p=.081), but the results indicate toward a correlation.
CONCLUSIONS: Athletes recognized more pain at the same intensity when their emotional state was unpleasant, but the RIII reflex was measured constantly so they could recognize less pain in an emotionally stable state. Despite some associations, no difference was observed in the degree of pain recognition based on injury experience.

PURPOSE: This study aimed to explore the direction of nutrition management and education for adolescent athletes based on the transtheoretical model (TTM).
METHODS: This cross-sectional study was conducted on 205 male adolescent athletes using questionnaires in Seoul and Gyeonggi provinces. Differences in nutritional indices, dietary behaviors, and dietary self-efficacies were compared according to the stage of dietary behavior change, and significance was verified using analysis of variance and chi-square tests.
RESULTS: According to the stage of change in dietary behavior, a significant difference was observed in the grade and score of the nutrition quotient (NQ), and the nutritional status and quality of meals were extremely poor in the precontemplation and contemplation groups. Dietary self-efficacy differed significantly according to the stage of change in dietary behavior. Compared to the pre-contemplation and contemplation stage groups, the action and maintenance stage groups had a higher willingness to practice desirable dietary behaviors and overcome barriers.
CONCLUSIONS: In this study, we demonstrated that individualized nutritional intervention based on TTM was an effective strategy for healthy dietary behavior and had a positive impact on adolescent athletes' sports performance. Furthermore, nutrition education should include content that enhances students' dietary self-efficacy.
