Protein ingestion prior to strength exercise affects blood hormones and metabolism

Article Abstract:

The acute hormonal and energy metabolism responses to a strength training session (STS) carried out three hours after breakfast in a normal training situation with or without 25 g of whey and caseinate protein mixture drink taken thirty minutes prior an STS is described. The pre-STS protein increases excess postexercise oxygen consumption and RER during two-hours recover after STS.

The VO2 slow component: Relationship between plasma ammonia and EMG activity

Article Abstract:

The relationship between the VO2 slow component, plasma NH3 concentration, and electromyography (EMG) responses during constant-load cycling is examined. The rise in NH3 concentration and the amplitude and spectral components of the EMG are consistent with a progressive increase in the recruitment of type II muscle fibers during the slow component phase of exercise.

Power output and muscle myosin heavy chain composition in young and elderly men

Article Abstract:

A study was conducted to observe the relationship between lower-limb power output characteristics, muscle myosin heavy chain composition, and lean limb volume. The results give proof of the importance of fast myosin isoform composition in the maintenance of dynamic muscle function in later life and particularly for maximal cycling performance.
