TL;DR: The results suggest that chondrocyte activity and bone metabolism promote in highintensity and low-frequency and long-duration in young mice, which may shed light on the underlying of the promotion of the longitudinal bone growth by exercise.

TL;DR: Investigation of diurnal activity patterns within groups of older adults classified by PAL, diurnal physical activity declined more in adults ≥66 years old with lower aerobic fitness, and active older adults maintained a larger amount of body movement for longer during their wake time.

TL;DR: It is suggested that CBEP did not have an added benefit for influencing physical activity over time amongst a population of previously sedentary adults.
