Methods Twenty‐four obese women completed an 8‐week supervised aerobic training program (3 sessions/week) assigned to either HIIT ( n = 11) or MICT ( n = 13). The HIIT protocol involved four 4‐min bouts at 85%–95% of the maximum heart rate (HR max ), while the MICT consisted of continuous walking/running for 41 min at 65%–75% of HR max . VAC was assessed using two methods: (1) the ratio of pulse wave velocity to global longitudinal strain (PWV/GLS), and (2) the ratio of arterial to ventricular elastance (E a /E es ). Results Both HIIT (−0.35 ± 0.01 to −0.31 ± 0.05 m/s%; p = 0.005) and MICT (−0.35 ± 0.01 to −0.30 ± 0.05 m/s%; p = 0.003) significantly improved the PWV/GLS ratio. However, only HIIT led to a significant reduction in the E a /E es ratio (0.88 ± 0.07 to 0.80 ± 0.09 mmHg/mL; p = 0.024), with a significant correlation between relative changes in PWV/GLS and E a /E es ratio ( r = 0.749; p = 0.008). Conclusions Both HIIT and MICT improved VAC as assessed by PWV/GLS ratio in young obese women. In contrast, elastance‐derived improvements (E a /E es ) were observed only following HIIT. These findings suggest that PWV/GLS may serve as a more sensitive and integrative marker for detecting exercise‐induced improvements in VAC. 10.1111/echo.70355 http://creativecommons.org/licenses/by/4.0/ |
