Resistance training with vascular occlusion: metabolic adaptations in human muscle

Article Abstract:

Results indicate that vascular occlusion potentiates metabolic changes seemingly by ischemic stimulus, which increases muscle glucose transport and adenine nucleotide catabolism after low-intensity resistance training without augmenting strength enhancement. Data show that 72 hour after an 8-week low-intensity resistance training, glycogen increases and ATP decreases in resting muscle.

Submaximal motor unit firing rates after 8 wk of isometric resistance training

Article Abstract:

Results demonstrate that 8 weeks of resistance training influences contractile properties of the muscle without altering control properties of the nervous system. The study shows a large increase in the maximal voluntary contractile force with smaller increase in evoked contractile speed without any measurable effects on the average motor unit firing rates.

Control of maximal and submaximal vertical jumps

Article Abstract:

Results indicate minor differences in the muscle timing between maximal and submaximal jumps as revealed by smoothed rectified electromyographic (SREMG) analysis. Data further point out to a generalized motor programs within the central nervous system whose output is influenced by amplitude and timing of the control signals.
