Objective: To examine factors in early life (up to age 5 years) that are associated with objectively measured physical activity in 11-12 year olds.
Design: Prospective cohort study.
Setting: Avon longitudinal study of parents and children, United Kingdom.
Participants: Children aged 11-12 years from the Avon longitudinal study of parents and children.
Main Outcome Measure: Physical activity levels in counts per minute (cpm) and minutes of moderate to vigorous physical activity for seven days measured with a uniaxial actigraph accelerometer.
Results: Valid actigraph data, defined as at least three days of physical activity for at least 10 hours a day, were collected from 5451 children. Several factors were associated with physical activity at ages 11-12 years. Regression coefficients are compared with the baseline of "none" for categorical variables: maternal brisk walking during pregnancy (regression coefficient 5.0, 95% confidence interval -8.5 to 18.5; cpm for <1 h/wk and > or =2 h/wk of physical activity 17.7, 5.3 to 30.1), maternal swimming during pregnancy (21.5, 10.9 to 32.1 and cpm for <1 h/wk and > or =2 h/wk of physical activity 24.2, 7.8 to 40.7), parents' physical activity when the child was aged 21 months (28.5, 15.2 to 41.8 and cpm of physical activity for either parent active and both parents active 33.5, 17.8 to 49.3), and parity assessed during pregnancy (2.9, -7.6 to 13.4 and cpm of physical activity for 1 and > or =2 parity 21.2, 7.1 to 35.3).
Conclusions: Few factors in early life predicted later physical activity in 11-12 year olds. Parents' physical activity during pregnancy and early in the child's life showed a modest association with physical activity of the child at age 11-12 years, suggesting that active parents tend to raise active children. Helping parents to increase their physical activity therefore may promote children's activity.

Background: Proprioceptive deficits are common among stroke survivors and can negatively impact their balance and postural control. However, there has been little evaluation of the change in proprioceptive deficits in the lower limbs over time after stroke. This study aimed to examine proprioceptive deficits over time after stroke in both the affected and "unaffected" lower limbs.

This review aims to conduct a meta-analysis of the impact of high-intensity training (HIT) on athlete jumping performance. As of May 2024, we conducted a comprehensive search on PubMed, Web of Science, SCOPUS, and EBSCOhost databases in accordance with the PRISMA guidelines. Use the PEDro scale to evaluate the methodological quality of the included study.

Background: This study investigated the acute effects of inspiratory muscle warm-up (IWU) on vocal performance in singers. Proper vocal and respiratory warm-up can enhance vocal range, quality, and endurance. The aim was to determine whether IWU improves maximum phonation time and pitch range, contributing to better voice production efficiency (vocal efficiency) and reduced fatigue.

Aim: Adequate pelvic floor support for the urethra is crucial for preventing stress urinary incontinence (SUI). Obesity is an established risk factor for SUI. This study aimed to explore the relationship between SUI and body composition, specifically focusing on muscle and fat mass.

Background: A brain healthy lifestyle, consisting of good cardiometabolic health and being cognitively and socially active in midlife, is associated with a lower risk of cognitive decline years later. However, it is unclear whether lifestyle changes over time also affect the risk for mild cognitive impairment (MCI)/dementia, and rate of cognitive decline.
Objectives: To investigate if lifestyle changes over time are associated with incident MCI/dementia risk and rate of cognitive decline.
