To the Editor Women continue to be highly underrepresented in cardiovascular rehabilitation (CR) research. Randomized clinical trials (RCTs) have demonstrated the similar and superior efficacy of high-intensity interval training (HIIT) on increasing peak oxygen uptake (peak Vo2) compared with moderate-intensity continuous training (MCT).1 However, these studies predominantly included men; HIIT in women with cardiovascular disease is, thus, recommended without empirical support.2 To address this gap, Khadanga et al3 evaluated the effect of HIIT combined with high-intensity lower extremity resistance training (RT) and MCT with moderate-intensity RT on peak Vo2 in women enrolled in CR. The key finding was that HIIT led to a significantly greater increase in peak Vo2 compared with MCT in women.
