TL;DR: Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings.

TL;DR: The long, self-administered IPAQ questionnaire has acceptable validity when assessing levels and patterns of PA in healthy adults and might introduce a source of error in criterion validation studies.

TL;DR: The results suggest that the subjective health assessments are valid health status indicator in middle-aged populations, and they can be used in cohort studies and population health monitoring.

TL;DR: The existing evidence reinforces the current efforts to promote cycling as an important contributor for better population health, and was strong for fitness benefits, moderate for benefits in cardiovascular risk factors, and inconclusive for all‐cause mortality, coronary heart disease morbidity and mortality, cancer risk, and overweight and obesity.

TL;DR: The effect of biological age at which unilateral loading was started (that is, the starting age of training relative to the age at menarche) on the difference in bone mass in playing and nonplaying arms of female racket-sport players was determined.
