Introduction: Research with Portuguese young athletes from team sports showed that mean heights and body masses of adolescent
basketball players exceeded the age specific 75th percentiles of reference data (Coelho e Silva et al., 2008). More recently and based on
a sample of 13- to 14-years-old soccer players, Figueiredo et al. (2009) noted a potential interaction between growth, maturation and
success in sports. The current study examines the effect of maturation on multiple aerobic measurements in a sample of adolescent RS
hockey players.
Material and methods
Anthropometry (stature and body weight), aerobic performance (20-meter shuttle run, SR) and aerobic power (Peak VO2 assessments
provided by a direct, maximal and progressive treadmill exercise test and following the criteria defined by Armstrong & Welsman, 2001)
were measured. Stage of pubic hair [PH] development was assessed at clinical examination (Tanner, 1962). Players were grouped by
chronological age [CA]: CA1: 14.5-15.4 years (n=25); CA2: 15.5-16.4 years (n=38). The effects of CA and PH were tested using t-student
while ANCOVAs were used to examine the effect of sexual maturation controlling for CA and for CA and body size simultaneously. Alpha
level was set at 0.05.
Results: During late adolescent years, body size, aerobic performance and aerobic power parameters were not sensitive to variation in
CA. When compared to players at stage 4 of PH, those classified at PH5 were significantly taller [t=-3.419, p
