TL;DR: New WHO 2020 guidelines on physical activity and sedentary behaviour reaffirm messages that some physical activity is better than none, that more physical Activity is better for optimal health outcomes and provide a new recommendation on reducing sedentary behaviours.

TL;DR: In this paper, a review of the latest developments with regard to physical fitness and several health outcomes in young people is presented, and the authors suggest that health promotion policies and physical activity programs should be designed to improve cardiorespiratory fitness, but also two other physical fitness components such us muscular fitness and speed/agility.

TL;DR: This systematic review provides key information about the following data collection and processing criteria: placement, sampling frequency, filter, epoch length, non-wear-time, what constitutes a valid day and a valid week, cut-points for sedentary time and physical activity intensity classification, and algorithms to estimate PAEE and sleep-related behaviors.

TL;DR: Strong evidence was found indicating that higher levels of cardiorespiratory fitness in childhood and adolescence are associated with a healthier cardiovascular profile later in life, and muscular strength improvements from childhood to adolescence are negatively associated with changes in overall adiposity.

TL;DR: A scientifically based harmonized definition of MHO is proposed, which will hopefully contribute to more comparable data in the future and a better understanding on the MHO subgroup and its CVD prognosis.
