PURPOSE: Machine learning (ML) refers to newly developed computer algorithms that are improved through iterative experiences. ML applications are expected to assist humans in analyzing large amounts of data. This review has outlined the application of ML in analyzing variable vital data such as walking steps, exercise intensity, heart rate, sleeping hours, sleep quality, resting heart rate, blood pressure, and calorie consumption in a day. Vital data consist of different variables that are closely related to genomic or exercise data. The prediction of healthy traits from a vital dataset has become a necessity in personalized medicine.
METHODS: Considerations and repeated tasks in supervised, semi-supervised, and unsupervised ML methods are presented. ML methods such as artificial neural networks, Bayesian networks, support vector machines, and decision trees have been widely used in biomedical studies to develop predictive models. Through vital data, these models can help in effective and accurate decision-making for a healthier life.
PURPOSE: Models based on genomic, exercise, and vital datasets provide a healthy lifestyle through regular exercise. We have provided guidelines to help in the selection of these ML methods and their practical application for variable vital data analysis.
CONCLUSIONS: Our guidelines could serve as a foundation for implementing both participatory medicine and data-driven exercise science.

PURPOSE: This study aimed to determine the role or applicability of aerobic exercise in erectile dysfunction.
METHODS: This narrative review was conducted by searching terms such as 'impotence,' 'erectile dysfunction,' 'erection dysfunction,' 'sexual dysfunction,' 'aerobic exercise,' 'aerobic training,' 'cardiovascular exercise,' 'cardiovascular training,' 'human,' 'randomized controlled trials,' and 'randomized clinical trials' in the titles or abstracts in PubMed, Google Scholar, Scopus, Wiley Online Library, and Science Direct databases.
RESULTS: Nine articles met the inclusion criteria. Aerobic exercise of light (low)-vigorous (high) intensity was found to be effective in erectile dysfunction in seven articles.
CONCLUSIONS: In case of mild-moderate erectile dysfunction accompanied by high blood pressure, obesity, physical inactivity, metabolic syndrome, acute myocardial infarction, and ischemic heart disease, it is suggested that following an aerobic exercise program has potential advantages. Further clinical research is required to compare nonlinear aerobic exercise with linear aerobic exercise in the population with erectile dysfunction.

PURPOSE: The present study aimed to investigate the effects of transdermal application of methylsulfonylmethane (MSM) on muscle damage and recovery following eccentric exercise in young men.
METHODS: Eleven college-aged men without any cardiovascular or orthopedic disorders underwent two sessions consisting of a control session (CS) and an experimental session (ES) in a random order with at least 2 weeks of wash-out between the sessions. The participants performed 30 maximal eccentric exercises involving their non-dominant elbow flexors in each session. Circumference, muscle soreness, range of motion, maximal voluntary isometric contraction (MVIC), and muscular echo intensity (EI) were measured to evaluate the changes in the level of exercise-induced muscle damage (EIMD). All measurements were performed at 24, 48, 72, and 96 hours after exercise and also immediately before and after exercise.
RESULTS: Transdermal application of MSM in ES attenuated muscle swelling and decreased MVIC after eccentric exercise when compared with CS. Muscle soreness and EI tended to increase less rapidly and decrease more rapidly in ES than in CS.
CONCLUSIONS: Transdermal application of MSM may induce relatively positive effects on EIMD and recovery following eccentric exercise when compared with the treatment that has been widely used previously.

PURPOSE: Muscle strength, power, speed, postural stability, and anaerobic power are important physical fitness factors required to perform well in a taekwondo competition. This study aimed to investigate the effects of 8 weeks of core balance and plyometric training on physical fitness in young taekwondo athletes.
METHODS: Nine young taekwondo athletes participated in this program. Body composition and relative fitness (muscle power, core strength, agility, postural stability, anaerobic power, and isokinetic muscle function) were measured before and after training. Data were analyzed using IBM SPSS Statistics version 23.0 (IBM Corp., Armonk, NY, USA). A paired t-test (pre vs. post) was used for the analysis.
RESULTS: The core strength measured by the sit-up count changed significantly after training (p<.05). In case of postural stability, the right absolute reach distance in the Y-balance test improved significantly after training (p<.05). In case of anaerobic power, the mean power (p<.01) and the peak power (p<.01) increased significantly after training.
CONCLUSIONS: We demonstrated that 8 weeks of core balance and plyometric training enhanced core strength, balance, and anaerobic power in young taekwondo athletes. Our results suggest that core balance and plyometric training are effective in improving muscle strength, core strength, balance, and anaerobic power.

PURPOSE: This study aimed to examine the effects of resistance and balance training on physical function and postural control in individuals with Down syndrome (DS).
METHODS: Ten adults with DS constituted the experimental group (EX) and attended an 8-week resistance and balance training program. The results were compared with those of the control group (CON), which consisted of 10 patients who did not undergo any physical training. Body composition, postural stability, and physical fitness were measured before and after the training program. Resistance and balance training were performed for 60 minutes, three times a week for 8 weeks.
RESULTS: Body weight, body mass index, body fat percentage, and waist circumference decreased significantly in the EX group after completing the 8-week resistance and balance training program. The center of pressure and the difference between standing foot pressure on the left and right were significantly improved in the EX group. Physical fitness including sit-to-stand repetitions and 10 m shuttle duration significantly improved in the EX and CON groups.
CONCLUSIONS: These results suggest that resistance and balance training to improve musculoskeletal problems is an effective strategy to prevent injury, fatigue, and falls during exercise and to improve general health in individuals with DS.

PURPOSE: This study aimed to investigate the effect of turmeric intake alone or in combination with resistance training on liver enzymes in adult men who regularly consumed alcohol at least twice a week.
METHODS: Twelve men (age: 36.0±5.26 years, weight: 99.9±17.9 kg, and height: 184.0±6.5 cm) were randomly assigned to the turmeric intake (2-3 g/day) alone (TI, n=6) group or the TI plus resistance training (60 minutes of RT 3 times a week) (TI+RT, n=6) group for 8 weeks. Blood was collected before and after 8 weeks of treatment. The analyzed variables included glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), γ-glutamyl transferase (γ-GTP), and GOT/GPT ratio.
RESULTS: There was no significant interaction effect in all variables, but the main effect was found in all variables only in TI+RT group. The Cohen's d effect size on the main effects of the TI+RT group on GOT (d=0.548), GPT (d=0.835), γ-GTP (d=0.623), and GOT/ GPT ratio (d=0.800) ranged from 0.548-0.835, respectively. However, body composition such as percent body fat (%, p>.05) and muscle mass (kg, p>.05) did not show the main effect on time points as well as the interaction effect (p>.05).
CONCLUSIONS: Although the 8-week TI treatment did not show any statistically significant change, TI treatment showed a tendency to decrease in GOT, GPT, and γ-GTP, and the GOT/GPT ratio tends to increase. Therefore, there was a synergic effect of the TI plus RT treatment or the sum of the two treatments for 8 weeks.

PURPOSE: This study aimed to understand the barriers to exercise and facilitators of exercise for up to 4 weeks following breast cancer surgery.
METHODS: A descriptive qualitative research method was used in this study. Twelve patients were recruited through purposive sampling immediately after breast cancer surgery.
RESULTS: Physical aspects (pain at the surgery site, reduction in the range of motion, and decrease in fitness), environmental aspects (difficulty in movement due to drain, lack of information on exercise), and psychological aspects (concerns about side effects, fear of pain, and fear of injury during exercise) were identified as barriers to exercise. Expectation of positive effects (recovery from surgery, prevention of lymphedema, usefulness for future radiation therapy, prevention of cancer recurrence, and health management) of exercise and social support (hospital education, support from medical staff, and exercise information received via mass media) were identified as facilitators of exercise.
CONCLUSIONS: We recognized different barriers to exercise and facilitators of exercise among patients who recently underwent breast cancer surgery. Future exercise intervention studies should consider minimizing such barriers and maximizing the facilitators identified in our study.

PURPOSE: Perivascular adipose tissue (PVAT) is a type of adipose tissue that surrounds vessels to provide anti-contractile effects. This study aimed to investigate the effect of resistance training on NADPH oxidase, adiponectin, and endothelial NOS (eNOS) expression in the abdominal aorta and PVAT of ovariectomized rats.
METHODS: Sprague-Dawley rats at 20 weeks of age were divided into three groups: sham control (Sham, n=10), OVX-control (OVX_ Con, n=10), and OVX-resistance exercise (OVX_Rex, n=10). Resistance training was performed by climbing a ladder for 12 weeks. Western blotting was used to analyze target protein expression in the rat abdominal aorta and PVAT.
RESULTS: NADPH oxidase (p67phox) expression was significantly higher in the OVX_Con group than in the sham group, but it was significantly decreased in the OVX_Rex group. The expression of adiponectin, AKT, and eNOS in both abdominal aorta and PVAT was significantly reduced in the OVX_Con group than in the Sham group, but it was improved in the OVX_Rex group.
CONCLUSIONS: The results suggest that regular resistance training inhibits p67phox and increases adiponectin expression and phosphorylation of AKT and eNOS in abdominal aortic PVAT of ovariectomized rats.

PURPOSE: Accumulation of senescent endothelial cells (ECs) and development of vascular aging have been implicated in the etiology of vascular dysfunction and disease. Aerobic exercise has been recognized as the single most effective non-pharmacological anti-aging intervention via increased laminar shear stress (LSS). This study aimed to determine the protective effects of LSS against premature senescence and the underlying mechanism.
METHODS: Carotid artery partial ligation surgery was performed on the left carotid arteries (LCAs) of C57BL/6J male mice to determine the effect of disturbed flow on the development of endothelial senescence. Senescence-associated β-galactosidase (SA-β-gal) staining was performed to measure cellular senescence. Expression levels of protein markers for cell senescence including p21, p16, and p53 were measured by western blotting.
RESULTS: En face SA-β-gal staining was identified only in the partially ligated LCAs of voluntary wheel-running mice, suggesting a direct relevance of LSS on the prevention of vascular senescence. In the in vitro H2O2-induced premature senescence model, preconditioning of high-flow LSS (20 dyne/cm2, 36 hours) induced significant reduction in the percentage of SA-β-gal positive ECs. Expression of the molecular markers of cellular senescence such as p21, p16, and p53 was significantly decreased by LSS pretreatment. However, the protective effects of LSS against premature senescence were completely abolished by SIRT1 inhibition.
CONCLUSIONS: The results suggest that high-flow LSS has protective effects against oxidative stress-induced premature endothelial senescence through a SIRT1-dependent mechanism.
