Abstract

Introduction: Sedentary behaviour (SB) may negatively influence cardiorespiratory fitness (CF) and adiposity in adolescents.

Objective: to analyse levels of CF and SB of overweight and obesity adolescents with different somatic maturation.

Material and Methods: 34 male adolescents (age: 16,1 ±1,5 years) were divided into three groups of somatic maturation (SM1 n = 12; SM2, n = 12 and SM3, n = 10). Years from peak height velocity (yPHV) was used to determine somatic maturation. Body composition (WC) was assessed by dual X-ray emission absorptiometry (DXA). CS levels were assessed using accelerometry. Relative VO2 peak was measured using a submaximal effort test on a fixed cycle ergometer.

Results: there was no significant differences in the SB (F (2.34) = 3.061, p = 0.061) and VO2 peak (F (2.34) = 1.328, p = 0.28) between maturation groups.

Conclusion: overweight and/or obese adolescents showed high levels of sedentary behaviour and presented VO2 peak below reference values for this population regardless of maturation status.
