The aim of the study was to examine associations between moderate-to-vigorous physical activity and sedentary time with sleep quality and quantity among preschool girls and boys using objective methods. Children (5-6 years old) attending kindergarten were recruited (n = 676). Measures included accelerometer-derived 24-hr activity and sleep for seven consecutive days. Longer time spent in moderate-to-vigorous physical activity was associated with higher sleep efficiency both in boys (p < 0.0001) and girls (p = 0447), and with lower Sleep Fragmentation Index in boys (p = 0.0042) and girls (p = 0.0494). Moreover, among boys, moderate-to-vigorous physical activity was inversely associated with wakefulness after sleep onset (p = 0.0006), number of awakenings (p = 0.0081) and Fragmentation Index (p = 0.0041), while in girls with sleep duration (p = 0.0405), Movement Index (p = 0.0128) and Sleep Fragmentation Index (p = 0.0494). Longer time spent sedentary was associated with lower sleep efficiency, and higher wakefulness after sleep onset, number of awakenings, Movement Index and Sleep Fragmentation Index-all with p < 0.0001. Furthermore, sedentary time was inversely associated with sleep duration both in boys (p < 0.0001) and girls (p = 0.0006), and directly associated with Fragmentation Index but only in boys (p = 0.0069). Meeting the recommended level of moderate-to-vigorous physical activity was associated with better sleep efficiency, lower wakefulness after sleep onset and number of awakenings among boys. All sleep-related variables showed significant differences between quartile groups according to sedentary time (p < 0.05) in both the total group and the boys. The sedentary time had the strongest, negative effect on sleep-related parameters in preschool children, therefore sedentary time reduction may contribute more to improving sleep quality than increasing moderate-to-vigorous physical activity.

Purpose: This study investigated elite German athletes to (1) assess their serum 25(OH)D levels and the prevalence of insufficiency, (2) identify key factors influencing serum 25(OH)D levels, and (3) analyze the association between serum 25(OH)D levels and handgrip strength.
Methods: In this cross-sectional study, a total of 474 athletes (231 female), aged 13-39 years (mean 19.3 years), from ten Olympic disciplines were included.
Effectiveness of dynamic neuromuscular stabilization training on strength, endurance, and flexibility in adults with intellectual disabilities, a randomized controlled trial.

Individuals with intellectual disabilities (ID) often exhibit lower levels of physical fitness compared to the general population, including reduced strength, endurance, flexibility, and coordination. Dynamic neuromuscular stabilization (DNS) training can potentially improve the performance of adults with ID caused by weak motor skills due to a lack of desirable nerve growth during childhood and before puberty. Also, DNS training proposed to improve physical fitness in this population, but the effectiveness and durability of DNS training on specific fitness components have not been well-established.

Purpose: As the global population of older adults rises, the United Nations Decade of Healthy Ageing (2021-2030) advocates for disease prevention, management, and enhancing overall wellbeing in older adults. We reviewed the MEDLINE literature under the MeSH term "music therapy" (MT), for its role in promoting healthy ageing.
Methods: A systematic search of the MEDLINE biomedical database (Ovid) was conducted using "MT" and "Ageing" as keywords, retrieving relevant full-text studies in English.
Cardiorespiratory fitness, cardiac morphology and function, and cardiovascular risk factors in long-term breast cancer survivors compared with non-cancer controls.

ProCardio Center for Innovation, Department of Cardiology, Oslo University Hospital, Oslo, Norway.
Background: Although anthracycline-related cardiotoxicity is widely studied, only a limited number of echocardiographic studies have assessed cardiac function in breast cancer survivors (BCSs) beyond ten years from anthracycline treatment, and the knowledge of long-term cardiorespiratory fitness (CRF) in this population is scarce. This study aimed to compare CRF assessed as peak oxygen uptake (V̇O), cardiac morphology and function, and cardiovascular (CV) risk factors between long-term BCSs treated with anthracyclines and controls with no history of cancer.
Methods: The CAUSE (Cardiovascular Survivors Exercise) trial included 140 BCSs recruited through the Cancer Registry of Norway, who were diagnosed with breast cancer stage II to III between 2008 and 2012 and had received treatment with epirubicin, and 69 similarly aged activity level-matched controls.

Background: Physical fitness and functioning are related to better mental health in older age. However, which fitness components (body composition, strength, flexibility, coordination, and endurance) are more closely related to psychological well-being (PWB) is unclear.
Methods: This research examined how body mass index (BMI) and six indices of functional fitness (i.
