Introduction: Cricket is a widely played sport, characterized by intermittent movement efforts of varying intensities such as bowling and batting. The study aimed to assess the effects of whole-body resistance band training on physical components of cricketers. Methods: Twenty state-level cricket players aged 18-25 years were included and randomly allocated into two groups. In control group (n=10), only regular cricket training was given, while in experimental group (n=10) resistance band training was given along with regular cricket training, 3 times/week for 6 weeks. The outcome measures: upper and lower abdominal strength, endurance, coordination, power, and balance of upper extremities were assessed at baseline and after 6 weeks. Results: The results suggested a statistically significant improvement in control group for upper & lower abdominal strength, power and balance of the upper extremity (p<0.05). In experimental group, all outcome measures showed statistically significant improvement (p<0.05). Between groups comparison indicated statistically significant difference for all outcome measures (p<0.05) except for upper abdominal strength (p=0.470) and upper body coordination (p= 0.146), suggesting more progress in experimental group than control group. Conclusions: The resistance band training along with regular cricket training improved the physical performance of cricketers, which may enhance overall performance and prevent injuries in cricketers.

Acute medical emergencies also occur in children and adolescents who participate in sports. Should a life-threatening situation arise, it is important that supporting supervisors are familiar with the correct application of resuscitation measures and regularly update their knowledge. Due to anatomical and physiological characteristics, children and adolescents sometimes show various injury patterns than adults and react differently to medical interventions. Knowledge of these differences helps in diagnosis as well as in therapy.

Top sporting performances are achieved by women and men. However, the performance of organs and metabolic processes varies due to different genetic and hormonal conditions. There is currently a considerable need for more research in this area. Sports science studies have mainly been carried out on male athletes and the data obtained is often not applicable to female athletes in the same way. The following article presents the current state of knowledge on physiological differences, the menstrual cycle, contraceptive methods and energy deficit in relation to athletic performance and training. This knowledge helps to provide comprehensive care and advice to female athletes in sports medicine practice.

Objectives: Low cardiorespiratory fitness, defined as a VO2 max below the 25th percentile for age and sex, is associated with greater body mass index (BMI), blood pressure, and plasma cholesterol values and is an independent risk factor for cardiovascular and metabolic diseases. Given that sedentarism has substantially increased in the U.S. population in the last 20 years and that office workers have the lowest cardiorespiratory fitness of the workforce, we aimed to assess the prevalence of low cardiorespiratory fitness in an corporate wellness program and determine its relationship with associated comorbidities.Methods: For this retrospective observational analysis demographics, height, weight, blood pressure at rest, plasma glucose, lipids, comorbidities, and VO2 max data was extracted from the medical records of 199 participants attending the Executive Health Program at M Health Fairview of the University of Minnesota. Participants were predominantly white, middle-aged men with near-optimal blood pressure values.Results: Participants with low cardiorespiratory fitness had a VO2 max [mean (range) of 28 (19.4 - 36.1) mL/kg/min], and was observed in 33% of all participants. Participants with low cardiorespiratory fitness were more likely to have higher BMI, dyslipidemia and hypertension than those in the excellent to superior category of cardiorespiratory fitness, VO2 max [mean (range) 45.6 (31.8 - 61.2) mL/kg/min]. Prevalence of obesity (17%) was lower than in the general U.S. population, and those who were obese were more likely to be of low cardiorespiratory fitness. Those with low cardiorespiratory fitness had a four fold relative risk of belonging to the group at high risk of cardiovascular and metabolic diseases when compared to those with a fair to superior cardiorespiratory fitness.Conclusions: Low cardiorespiratory fitness identified in a third of all participants, is a modifiable risk factor associated with risk for cardiovascular and metabolic disease, should be evaluated in executive health programs.
低心肺适能(定义为最大摄氧量低于年龄和性别的第25百分位数)与较高的身体质量指数(BMI)、血压和血浆胆固醇值相关，是心血管和代谢疾病的独立危险因素。鉴于在过去的20年里，久坐不动在美国人口中大幅增加，而办公室工作人员的心肺健康水平是劳动力中最低的，我们旨在评估企业健康计划中心肺健康水平低的患病率，并确定其与相关合并症的关系。方法:回顾性观察分析人口统计学、身高、体重、静息时血压、血糖、血脂、合并症和最大摄氧量数据，提取自参加明尼苏达大学M Health Fairview行政健康项目的199名参与者的医疗记录。参与者主要是白人中年男性，血压接近最佳值。结果:低心肺适能的参与者的最大摄氧量[平均值(范围)为28 (19.4 - 36.1)mL/kg/min]，在所有参与者中有33%出现这种情况。较低心肺适能的参与者比心肺适能优异至优异类别的参与者更有可能出现较高的BMI、血脂异常和高血压，VO2 max[平均(范围)45.6 (31.8 - 61.2)mL/kg/min]。肥胖的患病率(17%)低于美国一般人群，而那些肥胖的人更有可能是低心肺健康。与心肺健康水平较高的人相比，那些心肺健康水平较低的人属于心血管和代谢疾病高危人群的相对风险是后者的四倍。结论:在三分之一的参与者中发现了低心肺适能，这是一个与心血管和代谢疾病风险相关的可改变的危险因素，应在执行健康计划中进行评估。

Objectives: This exploratory mixed-methods study explored the barriers to physical activity, daily physical activity and submaximal exercise capacity among children with and at risk for cardiomyopathy and children with atrial septal defects.Methods: The study followed a convergent parallel mixed methodology design. Semi-structured interviews explored physical activity barriers. Seven-day accelerometry assessed moderate-to-vigorous physical activity, and an intermittent cardiopulmonary exercise test measured submaximal exercise capacity.Results: Twenty children, including 5 with cardiomyopathy (n=2 females, 14.2 ± 2.7 years old), 7 who were genotype-positive phenotype-negative for cardiomyopathy (n=5 females, 10.6 ± 3.3 years old) and 8 with atrial septal defects (n=4 females, 9.4 ± 3.8 years old) were recruited. Children with cardiomyopathy reported disease-specific physical activity barriers, while children who were genotype-positive phenotype-negative perceived barriers related to lack of time, parent support or activity motivation. The average daily moderate-to-vigorous physical activity was less than the recommended 60-minutes/day (n=20, mean 48.1 ± 18.0 minutes). Children with cardiomyopathy participated a median of 141.2 [interquartile range (IQR): 98.8) minutes of light-intensity physical activity and a median of 55.6 (IQR: 34.6) minutes of moderate-to-vigorous physical activity. The average submaximal exercise capacity was low (n=16, 25.2 ± 5.7 mL/kg/min). Estimated submaximal exercise capacity, including metabolic equivalent (4.5 ± 3.1 METs), respiratory exchange ratio (median = 1.0, IQR: 0.09) and ratings of perceived exertion (median = 7, IQR: 5) at peak exercise suggest that children with cardiomyopathy appear to have the exercise capacity to participate in low-to-moderate intensity activities.Conclusions: These novel data suggest that a diagnosis of cardiomyopathy may not preclude children from participating in a healthy, active lifestyle. However, they perceive disease-specific physical activity barriers and may require support to optimize their level of participation for optimal health.

Objectives: This study evaluated prior sports participation and training frequency during elementary to high school and their association with acute and overuse injuries in Japanese college students currently majoring in physical education.Methods: This retrospective study included 292 students who completed questionnaires that assessed their type of sport participation (single sport or multiple sports), training frequency (number of days per week), and injury history (acute and overuse) during the elementary, junior high, and high school periods.Results: In total, 47.9% (95% confidence interval [CI]: 38.2–57.7) of elementary school-aged athletes played multiple sports; this decreased to 22.3% (95% CI: 14.1–30.4) in junior high school and 5.5% (95% CI: 1.0–9.9) in high school. There was a significant difference in the training frequency between those who had overuse injuries and not in elementary (p < 0.05), and junior high school (p < 0.05).Conclusions: The results of this study suggest that participating in multiple sports through junior high school may lead to improved sports levels (i.e., participation in higher levels of competition). In addition, appropriate management of training frequency may help reduce the incidence of overuse injuries.

Objectives: The six-minute walk test (6MWT) is widely used in exercise based cardiac rehabilitation (EBCR) for assessment of functional capacity. The purpose of this study was to assess the effect of structured exercise in an EBCR program on 6MWT change and to determine the significance of age, gender, body mass index (BMI), pathology and exercise attendance on influencing this outcome.Methods: Data from a single centre 6-week (twice weekly exercise and education of one-hour duration) exercise-based cardiac rehabilitation program were analysed. Between 2006 and 2019, 2524 patients (males 1923, females 601, mean age 63.5 ± 11.2 years) with cardiovascular disease completed a pre and post 6MWT. Analysis included the effect of age, gender, pathology, BMI and exercise attendance on 6MWT outcome.Results: The group mean improvement in the 6MWT was 21.8% (pre 6MWT 432 ± 83, post 6MWT 527 ± 102 metres). The age-related improvement showed that both males and females achieved a post 6MWT results equivalent to the pre 6MWT result of patients two decades younger with improvement in the 6MWT unrelated to exercise attendance.Conclusions: The 6MWT provides simple safe method for assessment of functional capacity in an out-of-hospital environment being suitable for all ages. The post EBCR 6MWT results showed a group mean improvement in excess of 20% for both sexes. The decline per decade in 6MWT distance is less than 20 metres up to the sixth decade with a more marked decline from the sixth to the eighth decade, the decline being approximately 40-metres for both sexes in the eighth decade.

Objectives: This study aimed to conduct a warm-up (W-up) program incorporating movement preparation (MP) and clarify its effect on sports injury prevention.Methods: The subjects of the study were 55 first- to third-year students (age: 15.9 ± 1.0 years, height: 168.5 ± 5.2 cm, weight: 57.4 ± 5.3 kg) belonging to a high school boys' soccer team. The first two months were the control period (CP), and the next two months were the intervention period (IP). The CP was a conventional W-up and the IP was a W-up with MP. The effects of each W-up were compared in terms of the incidence of sports injuries and disabilities during both periods and the incidence of sports injuries and disabilities by cause. Other measurements were compared for a total of seven items, including flexibility, balance, and performance.Results: During the IP, the incidence of sports injuries during practice and the incidence of non-contact sports injuries were reduced, whereas flexibility, balance, and performance improved.Conclusions: W-up incorporating MP showed improvement in flexibility and related balance, which may have led to the reduction of sports injuries.

Objectives: Plyometrics has been used in sports training and many aspects of this modality are poorly understood. This study measures the magnitude of variations of serum creatine kinase (CK) activity and perceived muscle soreness after one session of Countermovement Jump (CMJ) session and compares 1 and 3 minutes rest intervals between each sets.Methods: A group of 30 young male was dividing in two groups and performed ten sets of ten CMJ with 1 or 3 minutes rest interval between sets. Before and after session (24, 48, and 72-h) they informed the muscle soreness perception and blood samples were collected for dosage of serum CK activity. Two (time) x Two (treatment) ANOVA was used to test differences in serum CK activity and muscle soreness. The alpha level was set at 0.05.Results: Serum CK activity measured 48 h after session augments ~2 and ~1.5 times in 1 min and 3 min rest interval respectively. No significant difference between groups that rests 1 or 3 minutes between sets was found. Muscle soreness rises 24 h after session without significant differences between groups.Conclusions: The findings show that the CMJ increases perceived muscle soreness and increases the serum CK activity, and the intervals of rest do not modulate these variables.
