Objective of the study was to identify the features of biomechanical and physiological efficiency of rowing in the process of modeling a competitive exercise by qualified academic rowers.
Methods and structure of the study. The competitive exercise was simulated by covering a 2000 m distance in laboratory conditions on the Concept-2 rowing ergometer. The study involved 23 rowers of the Russian junior national team, aged 16,52±0,59 years, body length 188,37±6,25 cm, body weight 85,96±8,66 kg. During the exercise, the parameters of external respiration, gas exchange and heart rate were recorded. The study of external respiration and gas exchange was carried out using the MetaLyzer 3B-R2 cardiorespiratory load diagnostics system from CORTEX (Germany). After the load, in the third minute of recovery, blood was taken to determine the concentration of La. The analysis was carried out by an express method using a portable automatic photometric device Accusport Lactate Meter (Boehringer Mannheim, Germany). Power, rowing tempo, and work per stroke were recorded using the Concept-2 ergometer processor and modified software.
Results and conclusions. It was revealed that the rowers of the «leaders» group had significantly higher body mass indices compared to the «team» rowers. Larger body dimensions of the «leaders» group rowers determined their advantage in terms of average rowing power, absolute values ​​of maximum aerobic performance (VO2 max), O2 pulse and work per stroke. Relative indices of special performance and aerobic performance calculated taking into account the body mass of the «leaders» and «team» rowers did not have significant differences. The study revealed that the achievement of high special performance by qualified academic rowers is largely determined by the level of biomechanical and physiological rowing efficiency (more advanced stroke technique and higher reserves of the aerobic energy supply mechanism), the informative criteria of which are the indices of work performed and energy expenditure per stroke.
