Effect of Endurance and Strength Training on the Slow Component of O2 Kinetics in Elderly Humans

We compared the effects of 8 weeks of high intensity, aerobic interval training (HIT) and isoinertial resistance training (IRT) on: i) V'O2 kinetics during heavy (HiEx) intensity exercise and; ii) work economy during moderate (ModEx) intensity exercise in 12 healthy men (69.3 ± 4.2 years). Breath-by-breath V'O2 and muscle deoxygenation ([HHb] by means of NIRS) were measured in HiEx and ModEx at identical workloads before and after trainings. In...
