This study aims to explore in depth how interval training with an Air Rower can be optimized to support maximum performance in rowing athletes. The research method applied is a true-experimental design with a pretest-posttest control group design, involving 20 male rowing athletes aged 18-20 years, divided into two groups: the control group (G1; n = 10), and the treatment group (G2; n = 10). The Anaerobic Interval Air Rower Training (AIART) program was conducted at an intensity of 85-95% HRmax, with a frequency of 3 times per week for 6 weeks. Data was collected by evaluating muscle strength using a dynamometer, while muscle endurance was tested using the upper body pull-up test performed over one minute. Data analysis was conducted using the independent sample t-test, and effect size evaluation was performed using Cohen's d.The results showed a significant increase in the mean delta (∆) muscle strength between G1 and G2 (0.50±0.97 vs 2.50±0.53 kg, p=0.001) and had a large effect size with a Cohen's d value of 2.558. Similarly, the mean ∆ muscle endurance showed a significant increase between G1 and G2 (0.21±0.67 vs 2.74±0.65 times, p=0.001) and had a large effect size with a Cohen's d value of 3.855. Therefore, it is concluded that the AIART intervention conducted over 6 weeks on rowing athletes is proven to be effective in improving muscle strength and endurance. © Copyright: Federación Española de Asociaciones de Docentes de Educación Física (FEADEF)
