Effect of high-intensity interval training on rowing performance in para-rowers

Introduction: High-intensity interval training (HIIT) is a performance-enhancing technique commonly used in training programs. Previously, HIIT has been reported to improve performance in regular rowing athletes, but there have been no studies on para-rowers. Objective: This study aimed to examine the effects of high-intensity interval training on 2000-m rowing performance in para-rowers. Methodology: A total of 12 participants were divided into two groups: an intervention group received a high-intensity interval training program (n = 6; 3 males, 3 females; age 36.83 ± 1.17 years; height 160.83 ± 1.83 cm; weight 55.38 ± 2.99 kg) and a control group performed a conventional rowing program (n = 6; 3 males, 3 females; age 35.67 ± 1.21 years; height 159.67 ± 1.86 cm; weight 54.67 ± 3.78 kg), performed 2 days per week for 6 weeks. The data used a paired t-test and independent sample t-test to compare the variables of 2000-m rowing performance between pre- and post- and compare between groups. Results: In the post-test of the experimental group, it was also found that the power output and rowing time were significantly different from the pre-test (p < 0.05). In the control group, there were no significant differences in the pre-test and post-test. Discussion: A key finding from this research is that appropriate HIIT training for Paralympic rowers increased power output and reduced rowing time (p < 0.05). In the control group, no significant difference was found in power output and rowing time for the 2000-meter distance. Conclusions: The high-intensity interval training 2 days per week for 6 weeks can improve rowing performance in the 2000-meter in para-rowers.
