Differences between Gender and Biological Age in Heart Rate Deflection Point during Progressive Maximal Intermittent Test in Young Athletes. JEPonline 2016;19(1):107-113. The purpose of this study was to compare the variables found in heart rate deflection point (HRDP) through the Carminattis’s Test (TCar) between young female and male in relation to maturation periods. Thirty five athletic teenagers (19 males, age = 16.6 ± 2.4 yrs and 16 females, age = 15.3 ± 2.5 yrs) underwent a progressive maximal intermittent field test after determination of sexual maturation. In order to identify the physiological transition points, the differences of the heart rate (HR) values derived from linear and polynomial fits using all HR points were calculated using the Dmax method. The Velocity Peak (VP) and the velocity measured on HRDP were lower in girls than in boys (P<0.05) in the pubertal and after-pubertal periods. The occurrence intensity on HRDP was also lower in the pre-pubertal boys compared to the after-pubertal boys (P<0.05). The percentage of HR peak on pubertal girls was lower than after-pubertal period girls (P<0.05). No significant differences were found in HR peak or in HR and %VP obtained at HRDP (P<0.05). The results suggest that the maturation period associated with gender plays an important role in physiological variables identified in TCar.
