Summary: This study found that there are associations between serum vitamin D metabolites and physical performance. 25-hydroxyvitamin D (25(OH)D) is negatively correlated with 2.4-km run time and positively correlated with muscle power, while 1,25-dihydroxyvitamin D (1,25(OH)(2)D) is positively correlated with run time and negatively correlated with strength and muscle power. 24,25-dihydroxyvitamin D (24,25(OH)(2)D) is negatively correlated with run time. The vitamin D metabolites together explain a small portion of variance in physical performance. VDR SNPs are not associated with physical performance.

Summary: The study found that strength endurance training performed better in ventral Bourban and T-test performances, while power training performed better in 1RM leg press, jump, sprint, and speed performances. The abstract also emphasizes the principle of training specificity and recommends the implementation of SET and PT in young female elite soccer players according to the respective training periods.

Summary: This study compared the effects of submaximal and supramaximal eccentric training on muscle structure and function. The results showed similar improvements in muscle power, hypertrophy, and hormonal responses between the two training approaches. However, only supramaximal training significantly increased single-leg jump height and one-repetition maximum strength. Therefore, the use of supramaximal loading may not be necessary for healthy, active individuals.

Summary: This study aimed to investigate the usefulness of the Running-based Anaerobic Sprint Test (RAST) in estimating anaerobic performance in trained and untrained U12 girls, and the effect of an 8-week training period on anaerobic performance in female U12 soccer players. The results showed a significant increase in anaerobic performance in the trained group, and a strong correlation between the traditional Wingate test (WAnT) and the RAST in assessing anaerobic capacity. The simplicity of the RAST encourages its use in monitoring anaerobic capacity in both trained and untrained girls.

Summary: This study aimed to determine the differences in body composition and specific motor abilities in relation to position. The results showed a strong link between body composition and specific motor abilities, but the level of significance and variables varied in relation to the players' position. Based on these findings, coaches and those in the soccer industry should adopt a tailored approach in planning the development of specific motor abilities and emphasizing the importance of balanced body composition.

Summary: This study found that standing core exercise can induce changes in circulatory and hemodynamic responses only when the rotational cadence is set at a faster speed. Fast rotational core exercise can improve cardiac output and femoral blood flow, providing some scientific evidence for the design of exercise programs.

Summary: This study analyzed the relationship between body morphology and vertical jump performance, and compared the morphological features of high and low performing professional soccer players. The results showed that regional morphological features had higher correlations with vertical jump performance than whole body features. Significant differences were found in upper and lower limb morphology between high and low performers, while no differences were observed in whole body features. These findings suggest that using morphological features specific to body regions may provide a better interpretation of the physical potential of soccer players in jump performance.

Summary: The aim of this study was to evaluate the effect of exercise interventions on glycaemic control in children and adolescents with type 1 diabetes mellitus (T1DM) and to examine the characteristics of the interventions. The study found that exercise interventions longer than 24 weeks, with at least 60 minutes of high-intensity exercise per session, may serve as a supportive therapy for metabolic control in youth with T1DM.

Summary: This study conducted a meta-analysis to examine the association between glycated hemoglobin and physical activity, sedentary behavior, and physical fitness in children and adolescents with type 1 diabetes. The findings suggest that low levels of physical activity and cardiorespiratory fitness, as well as extensive sedentary behavior, may contribute to poor glycemic control in youth with type 1 diabetes.

Summary: Understanding the impact of COVID-19 on muscle strength can provide insights into the organs involved in acute and chronic COVID-19 sequelae. This study investigated the muscle strength of long-COVID-19 patients compared to a control group, and found that grip strength and leg extension strength were significantly lower in COVID-19 survivors. The relationship between long-COVID syndrome and muscle strength was partly mediated by the lower appendicular lean mass index (ALMI).

Summary: Exercise intolerance remains a major unmet medical need in patients with heart failure, and skeletal myopathy is considered as the major limiting factor. Recent studies have suggested that circulating myokines synthesized and secreted by skeletal muscle may provide new insights into the pathophysiology and classification of HF-related skeletal myopathy. These myokines may also serve as biomarkers to personalize physical training for patients with HF and exercise intolerance. Furthermore, the production and secretion of myokines in patients with HF may interact with systemic alterations and affect cardiac structure and function, which can influence adverse cardiac remodeling and clinical outcomes in HF patients.

Summary: The aim of this study was to evaluate the relationship between fear of hypoglycemia and physical activity and glycemic metrics in children and adolescents with type 1 diabetes. The results showed that patients with fear of hypoglycemia were more active, less sedentary, and had similar glycemic metrics to those without fear. Therefore, fear of hypoglycemia may be less of a barrier to an active lifestyle than previously believed.

Summary: This study aims to evaluate the impact of a 12-week gamified family-based health and exercise intervention on physical fitness, basic motor competencies, mental and behavioral health, and adherence to 24-h movement guidelines in children aged 4 to 5 years old. The study will assess changes in sedentary levels, physical fitness, basic motor competencies, mental and behavioral disorders, adherence to the exercise program, and compliance with physical activity recommendations. The exercise group will undergo a 12-week exercise intervention, while the routine care group will receive routine care for 12 weeks followed by a control period.

Summary: This study aimed to understand the cardiometabolic factors in hip and knee osteoarthritis (OAD) and their association with different body composition phenotypes characterized by muscle mass and adiposity. The study found that OAD is associated with hypertension and increased cardiovascular risk in older adults. The low muscle mass/high adiposity phenotype is particularly related to cardiometabolic factors.
