Strength
training has become a major component sports and rehabilitation. We have
developed an exercise paradigm that combines three modalities known to
positively influence strength. 21 female subjects were recruited, whereof
12 were trained. Before and after 5.5 weeks of training, oxygen consumption,
lactate levels and body composition were determined, muscle biopsies were
acquired, and dynamic 31P spectroscopy measurements were performed.
Capillary-to-fiber-ratio, calf lean mass, peak power, resting pH, and resting
inorganic phosphate and phosphocreatine concentrations changed significantly
with training. A large increase in enhancement of metabolic parameters in a
short time is therefore possible using this new exercise paradigm.
