Passive warming has therefore received attention because it can effectively maintain an elevated muscle temperature (Tm) after a warm-up. The present study aimed to investigate the effects of local passive warming (LPW) administered during the transition phase between active warm-up and isokinetic exercises.METHODS: Eleven healthy men participated in this randomized crossover study. During the 30-minute transition period, a customized water-perfused warming pad was placed on the anterior thighs of the dominant legs (+3°C or +6°C based on the baseline skin temperature) or no intervention for the control group (CON). Subsequently, the total work, peak torque, and average power during isokinetic knee extensions (10 repetitions at a speed of 60°/sce) were measured. Using surface electromyography (EMG), the root mean square and mean frequency from the rectus femoris during knee extension were measured to assess neuromuscular activity.RESULTS: Total work (+6°C 1,289.8±389.3 vs. CON 1,437.3±408.2 Nm, p=.042), peak torque (+6°C 146.0±33.3 vs. CON 162.9±37.9 Nm, p=.022), and average power (+6°C 77.7±19.8 vs. CON 90.2±25.3 W, p=.012) were lower in the LPW +6°C group than in the CON group. EMG RMS was lower in the LPW +6°C group than in the CON group (+6°C 58.4±22.3 vs. CON 78.6±33.0 % MVC, p=.005). MF was higher in the LPW +6°C group than in the CON group (+6°C 87.5±12.4 vs. CON 81.4±11.0 Hz, p=.016).CONCLUSIONS: Local passive warming administered during the transition phase was not an appropriate strategy for boosting the performance of subsequent isokinetic exercises. Accordingly, the application of passive warming should be carefully chosen before exercise commences.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42617047","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}

Folate is an essential methyl donor in the epigenetic programming of offspring. This review and meta-analysis was conducted to compile the evidence reported thus far to identify associations between maternal folate status and childhood obesity.METHODS: A keyword/reference search was performed in EBSCOhost and Web of Science databases. A CMA program was used for a meta-analysis to estimate the pooled effect of maternal folate status on childhood obesity in offspring and to examine the influence of moderating variables on the overall effect.RESULTS: Better maternal folate intake was associated with a lower risk of childhood obesity: the overall effect size (ES; Hedges’ g) was 0.168 (95% CI=0.075 to 0.260, p<.001; small effects; cf., Cohen’s criteria). Moderator analysis revealed that the ≥Q statistic for the age group was statistically significant (Qb=4.730, df=1. p=.030; heterogeneity of ES). In offspring <7 years and >7 years, the ES was 0.277 (95% CI=0.151, 0.404) and 0.089 (95% CI=-0.025, 0.202), respectively. The study design was a statistically significant variable (Qb=4.310, df=1. p=.038; heterogeneity of ES). In cohort studies, ES was 0.251 (95% CI=0.135, 0.367), whereas in randomized controlled trial group, ES was 0.062 (95% CI=-0.073, 0.197).CONCLUSIONS: Maternal folate intake significantly affects childhood obesity, and the effect of maternal folate status is stronger inchildren younger than 7 years.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67216663","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}

During sports competitions, data were collected using global positioning system (GPS) units (10 Hz), and information on sport-related injuries of the lower extremities was recorded. The acute-to-chronic workload ratio (ACWR) of total distance covered, high-intensity distance (≥18 km/hours), sprint distance (≥21 km/hours) and bouts, work-torest ratio, and acceleration-deceleration bouts were calculated. Data were evenly split into quartiles, with the lowest ACWR range used as a reference group. Odds ratios were calculated to determine the injury risk at a given ACWR of each GPS variable, using a logistic regression analysis.RESULTS: Six players experienced nine injuries, yielding an incidence of 132.93 injuries per 1,000 athlete exposures. Based on ACWR values, the highest risk of injury was most associated with total distance covered, followed by high-intensity distance, and sprint bouts. The lowest risk of injury was associated with sprint distance, which yielded a lower injury risk than that in the reference group.CONCLUSIONS: Our study shows the need for continued monitoring of in-game athlete performance in preventing non-contact sportrelated injuries in football players.","PeriodicalId":36291,"journal":{"name":"Exercise Science","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46377012","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}

Attacks and counter-attacks for all types of taekwondo permit the legal scoring of kicking techniques directed toward the head/face/neck (i.e., head kicks) and torso, though punching the head region is illegal. Given the kicks used in S-TKD, there is a high risk for brain and musculoskeletal injury in competition and training sessions. A number of studies have reported injury rates in S-TKD competitions [1-9]. In one report, 1,466 injuries occurred in 283 athletes during training, with an average of 5 injuries per athlete annually [10]. A meta-analysis found an injury rate of 79 per 1,000 athlete-exposures (A-E) in taekwondo competitions [6]. Similarly, a recent study of an S-TKD team from Korea has reported injury incidence rates in training sessions and competition of 5 and 25 per 1,000 A-E, respectively [9]. In addition to the musculoskeletal injuries in S-TKD, there is a high risk of concussion, ranging was from 0.0 to 50.2 per 1,000 A-E [11] which is anticipated since a direct kick to the opponent’s head region is legal and promoted by the competition rule. Additionally, changes made by the sport’s governing bodies (i.e., World Taekwondo (WT) and Korea Taekwondo Association (KTA) include a recent competition rule (i.e., 2018) where a valid head kick (HK) will be awarded from a minimum of 3 points to a maximum of 5 points (i.e., given higher points).

METHODS: Exposure and injury data were collected from 49 professional baseball players in a single team who participated in official games during the 2021 KBO league season. Injury data included injured body parts, injury mechanisms, injury diagnoses, activities, playing positions, and time-loss (TL). Injury rates (IRs) were calculated using the athletic-exposure (AE) and time-exposure (TE) meth-ods. RESULTS: In total, 158 injuries were reported during the study period. The overall IR was 58.0 per 1,000 AE and 5.3 per 1,000 exposure times (TE). Approximately 68.4% of all injuries were non-TL (NTL) injuries, and which was approximately 2.2 times higher than TL injuries.
