TABLE 1.
Anthropometric data of the cohort. The activity level is based on the Freiburg questionnaire of physical activity. Maximal power relative to body weight has been considered for the countermovement squat jump. Peak force relative to body weight has been considered for the one leg hopping. Age, activity level, relative power and force comparisons are done within the age group. The Esslinger Fittnes Index (EFI) is an estimation of the physical fitness level normalized for sex and age.
