Recovery cardiac cost following short duration high intensity exercise in prepubertal, just pubertal, and postpubertal girls and its relationship with physical and physiological parameters.

Recovery cardiac cost (RCC) after short duration high intensity exercise and its relationship with physical and physiological parameters were assessed for 45 sedentary girls aged 10-25. RCC of postpubertal girls were significantly lower than those of prepubertal and just pubertal girls, when expressed in terms of cost in beats above rest. No significant differences were found among the three groups regarding RCC values in terms of % cost above rest. Age and diastolic blood pressure were negatively correlated with RCC both in terms of cost in beats above rest % cost above rest only in postpubertal group. Pre-exercise heart rate in post-pubertal group was negatively correlated with RCC only in terms of % cost above rest. No positive or negative correlation was found between RCC and other parameters under study, in prepubertal and just pubertal groups.
