Assessment of the effect of anthropometric data on the alterations of cardiovascular parameters in Lithuanian elite male basketball players during physical load

Objectives. The aim of the study was to assess the effect of the anthropometric data of basketball players on the alterations of cardiovascular parameters during the physical load applying the model of integrated evaluation. Material and Methods. The research sample consisted of 113 healthy Caucasian male basketball players, candidates of the Lithuanian National men’s basketball teams. Basketball players were divided into 2 groups: 69 taller and heavier male basketball players (with higher percentage of body fat) (TMB) and 44 shorter and less heavy male basketball players (with lower percentage of body fat) (SMB). The amount of fat, expressed in percentage, was measured using the body composition analyzer TBF–300. “Kaunas-Load,” a computerized ECG analysis system, was used to evaluate the functional condition of the cardiovascular system during the load. Results. The TMB group had a lower heart rate during the warming-up phase and the steady state of the load as compared with the SMB group (P<0.05). The JT interval in the TMB group was greater during the warming-up and the steady state as compared with the SMB group (P<0.05). The JT/RR ratio index in the TMB group was found to be lower in the warming-up phase and in the steady state compared with the respective parameter in the SMB group (P<0.05). Conclusions. The cardiovascular system of taller and heavier male basketball players with a greater relative amount of body fat functioned more economically
