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.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45586018","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44151947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48374981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of exercise intervention in reducing the risk of cardiometabolic disease in NWO have not been fully elucidated. Therefore, this review aimed to summarize the potential cardiometabolic disease risk and to provide implications of exercise interventions for the proactive prevention of cardiometabolic disease risk in NWO.METHODS: We searched and summarized the literature on the cardiometabolic risk factors in NWO. In addition, we summarized literature investigating the effects of exercise intervention on the cardiometabolic risk factors in NWO. We performed the literature search using PubMed, Web of Science, and Google Scholar databases.RESULTS: NWO was associated with increased visceral fat, ectopic fat, oxidative stress, inflammatory cytokines, insulin resistance, dyslipidemia, and subclinical atherosclerosis compared with normal weight lean. NWO requires exercise interventions that induce alterations in body composition, such as decreased body fat percentage and increased muscle mass. Resistance exercise (RE) and high-intensity interval exercise (HIIE) can improve lipid components and alter body composition in NWO. In addition, low-intensity blood flow restriction resistance exercise (BFR-RE) may enhance muscular strength and anaerobic power in NWO.CONCLUSIONS: The cardiometabolic disease risk is increased in NWO. We suggest that exercise interventions (RE, HIIE, and BFR-RE) may effectively prevent cardiometabolic disease risk and alter body composition in NWO. As this has potential implications for exercise interventions in NWO, further investigations are needed to find the optimal exercise for proactive prevention of cardiometabolic risk in NWO.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47270309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pilates and core stability exercise programs were applied in each group for 8 weeks. Before and after the two exercise programs, BMD, Tinetti Performance Oriented Mobility Assessment (Tinetti POMA), and balance ability were measured.RESULTS: There were no differences in BMD among the three groups depending on the application of the exercise program. The balance scores of the Tinetti POMA and total Tinetti POMA scores in both the PG and CSG were higher after the 8-week exercise program. In particular, the gait score of the Tinetti POMA in the PG was higher than that in the CSG. Static and dynamic balance abilities improved in both the PG and CSG.CONCLUSIONS: These results suggest that Pilates and core stability exercises can be effective for improving balance ability, leading to the prevention of falls in older adult women.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46607859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
