A Comparison of the Effect of High-Intensity Interval Resistance Training and Traditional Resistance Training on the Performance and Physiological Indicators in Young Female Rowers

Resistance training can improve performance in power and speed sports. This study aimed to compare the effect of 8 weeks of high-intensity interval resistance training (HIIRT) compared to traditional resistance training (RT) on the performance and physiological indicators of young female rowers.

Sixteen young female rowers who had more than 3 years of professional rowing experience were randomly divided into two groups: RT and HIIRT (n = 8 in each group). Resistance training for two groups was performed in the form of RT and HIIRT for 8 weeks, three sessions per week, with additional training (three rowing sessions + one session of ergometer + two sessions of running and central stability training). Functional tests and physiological adaptations were measured before and after the RT and HIIRT programs.

The statistical analysis of the data showed that the 2000-m rowing ergometer performance improved significantly in both groups (P < 0.0001). The magnitude of this performance increase was greater in the HIIRT group. Maximum oxygen consumption (VO_2max) in the HIIRT group revealed a significant difference before and after 8 weeks of training (P = 0.002). Changes in the respiratory exchange rate (RER) were significantly affected by both RT and HIIRT (P < 0.01). However, changes in lactate levels were not significant in either training group (P > 0.05).

According to the results of the present study, it seems that HIIRT is more effective than traditional RT exercises in enhancing the physiological characteristics and performance of young female rowers.
