Key result
Dynamic training improved exercise endurance and significantly increased anaerobic glycolysis capacity in patients with chronic heart failure, without altering muscle fiber distribution.
Why the study?
Does dynamic training improve skeletal muscle fiber distribution, metabolic enzyme activities, and electrophysiology in patients with stable chronic heart failure?

Supports dynamic training to boost submaximal endurance in stable CHF; extends evidence for metabolic adaptations independent of fiber-type shifts.
Does dynamic training improve skeletal muscle fiber distribution, metabolic enzyme activities, and electrophysiology in patients with stable chronic heart failure?
Dynamic training in CHF patients improves exercise endurance and increases anaerobic glycolysis capacity in skeletal muscle, independent of changes in muscle fiber distribution or capillarity.
Kiilavuori et al. (2000) studied this question. Dynamic training improved exercise endurance and significantly increased anaerobic glycolysis capacity in patients with chronic heart failure, without altering muscle fiber distribution.
