We aimed to develop cut
-points for directly measured peak oxygen uptake (VO2peak
) to
identify boys and girls at increased cardiometabolic risk using different scaling methods to
control for body size and composition. Altogether 352 children (186 boys, 166 girls) aged 9
–
11 years were included in the analyses. We measured VO2peak directly during a maximal cycle
ergometer exercise test and lean body mass (LM) by bioelectrical impedance. We computed a
sex
- and age
-specific cardiometabolic risk score (CRS) by summing important
cardiometabolic risk factors and defined increased cardiometabolic risk as >1 standard
deviation above the mean of CRS. Receiver operating characteristics curves
were used to
detect

Associations of fitness, motor competence, and adiposity with the indicators of physical activity intensity during different physical activities in children
Haapala, Eero A; Gao, Ying; Hartikainen, Jani; Rantalainen, Timo; Finni, Taija (Nature Publishing Group, 2021)We investigated the associations of peak oxygen uptake (V̇O2peak), ventilatory threshold (VT), muscle strength, motor competence (MC), and adiposity with the indicators of PA intensity during different physical activities ... -
Allometrically scaled explosive strength, but not static strength or maximal oxygen uptake is associated with better central processing time in young males
Narimani, Mohammad; Esmaeilzadeh, Samad; Pesola, Arto J.; Haapala, Eero A.; Heidari, Behrouz; Azevedo, Liane B. (Edizioni Minerva Medica, 2020)BACKGROUND: We aimed to examine the associations of cardiorespiratory fitness (CRF), static strength and explosive strength with cognitive functions in young males. METHODS: Eighty-six young males (age 16-24 years) ... -
