Background It is estimated that, worldwide, 9% of deaths occur as a result of insufficient physical activity (PA) practice. Practicing PA can prevent and/or reduce the deleterious effects of different types of diseases and can improve general health aspects related to health-related quality of life (HRQoL). Purpose To analyze the relationship of d...

Session ratings of perceived exertion (sRPE) are considered a practical marker of whole session exercise intensity, but its relationship to exercise volume has remained unclear. We analyzed the effects of exercise duration at different intensities on overall and differentiated sRPE. Sixteen males (Mage = 22.6, SD = 2.2 years; Mheight = 176.4, SD =...

Given the reduced proportion of the 24 hours of the day spent with moderate to vigorous physical activities, there has been a recent appreciation of integrative and compositional approaches of the different behaviors adopted throughout the day for interpretations of health outcomes. This study points out the importance of integrating sleep time, se...
Article
This study aimed to examine the independent and combined effects of pubertal and weight status on concurrent measurements of peak oxygen (VO2peak) in school aged adolescent males. The final sample included 49 boys (12.3 ± 0.8 years). VO2peak was derived from an incremental progressive maximal protocol using a motorized treadmill. In addition, maxim...

This study compared maturation, body composition and physical fitness between youth soccer athletes with different technical skills levels. Sixty-two young athletes (11-17 years) were categorized dichotomously in more skilled (n=31) and less skilled (n=31) groups based on 3 specific technical tests (Dribbling Speed Test [DST], Shuttle Dribble Test...

Project
This project aims to explore the association between 24-hours movement behaviors and health indicators in adults. Physical activity, sedentary behavior and sleep will be assessed using ActiGraph w-GT3X-BT accelerometers over seven consecutive days. Questionnaires and video call interviews will be carried out to assess health indicators variables.
