Comparison of the effect of ۴ weeks of polarized and traditional training on ۲۰۰۰ m performance and physiological indicators in elite rowers

The aim of the present study was to compare the effect of ۴ weeks of polarization training and traditional training intensity distribution on ۲۰۰۰ m performance and physiological parameters in elite rowers.۲۰ athletes (۱۰ women and ۱۰ men) who had more than two years of professional rowing experience were divided into two groups of polarized training model (۲۰-۱۵ ٪ ۱۰ ۵ ٪ - - ۸۰ ۷۵٪) and traditional trainingintensity distribution (۳۰ ٪ ۵۰ ٪ ۲۰٪ ) were divided and followed their training programme for four weeks which was six training sessions per week (three rowing sessions + one ergometer session + two running sessions). performance and physiological adaptations were assessed before and after the training period.Statistical analysis of the data showed that the performance of ۲۰۰۰m in both groups improved significantly (P <۰.۰۰۰۱). The magnitude of this performance improvment was greater in the polarized group. Despite improving performance and reducing the time of ۱۰۰۰ meters rowing in elite rowers after four weeks of polarizing training, these changes were not significant (P = ۰.۳۷). Maximum oxygen consumption increased in both groups but were not significant (P = ۰.۱۴). Changes in respiratory rate ratio were not significantly affected by training protocol (P = ۰.۲۱). Fat percentage decreased significantly in both groups (P = ۰.۰۰۱).According to the results of the present study, it seems that the polarization intensity distribution pattern is a more effective method than traditional exercises for developing endurance and aerobic characteristics of rowing athletes.
