Graded exercise testing (GXT), per a cycle-ergometer (CE), offers safety and monitoring advantages over treadmill (TM) GXT. Unfortunately, CE-VO2max and some other cardiorespiratory (CR) variables are frequently lower than TM-GXT values. It has been difficult to compare TM and CE-GXT values. However, it was hypothesized that standing towards the conclusion of the CE-GXT (Stand-CE) might increas...

Un modèle formel est une représentation mathématique, abstraite et toujours approchée d’un système réel. Il représente une certaine vue de ce système. Il est le résultat d’une démarche cognitive complexe qui progressivement rend formel et explicite un ensemble d’exigences, de contraintes, de connaissances informelles et partiellement implicites.

BACKGROUND Compulsive exercise (CE) has been proposed as significant in the etiology, development and maintenance of eating disorders (EDs), resulting in more severe and enduring pathology.

We aimed to test if adolescents show the same associations between CE and other clinical variables as previous research has f...
