What governs skeletal muscle VO(sub)2max? new evidence

Article Abstract:

Results demonstrate existence of a diffusion gradient from blood to muscle and metabolic rates of trained skeletal muscle increase with increasing oxygen supply. Data also indicate that under hyperoxia, trained human skeletal muscle exhibits disproportionate intracellular partial pressure and maximal oxygen consumption.

Metabolic and vascular limb differences affected by exercise, gender, age, and disease

Article Abstract:

The similarities and differences in exercising muscle blood-flow control in the upper and lower limbs are evaluated, with respect to exercise onset kinetics, intrinsic vasoreactivity of the resistance vessels at rest and during exercise and the role of gender and the aging process in limb-specific responses. Results show that inherent limb differences, in terms of skeletal muscle metabolism and blood flow, do exist, and elucidating the mechanisms underlying limb-specific adaptations would be important for interpreting abnormal vascular function attributable to healthy aging and disease.

Maximal strength training of the legs in COPD: A therapy for mechanical inefficiency

Article Abstract:

A study was designed to investigate the impact of short-term maximal strength training (MST) on patients with chronic obstruction pulmonary disease (COPD). The findings suggest that since MST is minimally taxing to the ventilatory and cardiac systems, it is well suited to patients with COPD.
