Relationship between resistance training and functional capacity

CHRONIC HEART FAILURE
Our study showed improved functional capacity in post-CABG patients after just 4 weeks of resistance training, with higher METS and 6-MWT distance. In chronic heart failure patients, resistance training alone significantly improved 6-MWT compared to the non-training group. The clinical significance of this benefit for chronic heart failure patients remains to be determined. Notably, in CABG patients, a 6-MWT distance of less than 250 m is associated with a higher risk of rehospitalization, with a relative risk of 16.74 (95% CI: 2.53–110.78, RT enhances maximal workload tolerance through peripheral muscle adaptations like increased cross-sectional area, capillarization, and oxidative capacity [Peak VO2 is the gold standard for cardiorespiratory fitness, but it wasn't measured due to equipment limitations on gas analyzer [
