Formation of Specialized Targeted Loads of "Critical" Power in Qualified Athletes in Rowing

Introduction. Modern trends in sports preparation improvement are based on the full understanding of the problem of formation of the specialized orientation of the training process, in particular modeling of training loads which meet the requirements of functional support of competitive activity according to a sport, specialization, age and qualification of athletes [2]. The results of the meta-analysis gave grounds for the research of highly specialized directions of modeling of the NCP of the target orientation taking into account the functional maintenance of structural components of the competitive activity, in particular on the second half of a distance of 2000 m in rowing. The aim of the study is to determine the quantitative and qualitative characteristics of training load regimes at critical power, and to experimentally validate their targeted application in the system of specialized physical training for qualified athletes in rowing. Material and methods: qualified male athletes specializing in rowing. Age: 24.1±2.3 years, open weight category. Qualification: members of the provincial teams of Shandong, Jiangxi, and Sichuan (n=35). Methods: meta-analysis of specialized literature, physiological research methods, and ergometry. esults. The first training mode consisted of prolonged training loads at an ergometric load level corresponding to VO₂ max. The second mode involved repeated training exercises performed at critical power load, recorded at 115% of VO₂ max. The third mode included prolonged training loads at the ergometric power level recorded at the onset of the linear decline in work intensity during the execution of rowers' start actions. Indicators of energy power, aerobic and anaerobic energy supply, recorded in the VO₂ max, CP, and CPFT test series, correspond to model characteristics of high-class rowers' functional fitness.Conclusions. Indicators of oxygen consumption, blood lactate concentration, and ergometric power recorded during repeated test load performances indicate the realization-based nature of the experimental work regimes. This forms a substantive foundation for accumulating training load regimes in sessions aimed at developing functional capabilities under conditions of steady state, fatigue development and compensation, and transitional processes between them.
