Since it became clear that K+ shifts with exercise are extensive and can cause more than a
doubling of the extracellular [K+]([K+] s) as reviewed here, it has been suggested that these …

Failure to maintain the required or expected force, defined as muscle fatigue, is
accompanied by changes in muscle electrical activity. Although studied for a long time …

The manifestations of fatigue, as observed by reductions in the ability to produce a given
force or power, are readily apparent soon after the initiation of intense activity. Moreover …

Intensive activity of muscles causes a decline in performance, known as fatigue, that is
thought to be caused by the effects of metabolic changes on either the contractile machinery …

The purpose of this study was to compare the magnitude and mechanisms of ankle
dorsiflexor muscle fatigue in 20 young (33±6 yr, mean±SD) and 21 older (75±6 yr) healthy …

Background: Tissue iron depletion may negatively affect endurance performance and
muscle fatigability. Objective: We investigated tissue-level iron depletion and progressive …

The effect of the distribution of rest periods on the efficacy of interval sprint training is
analysed. Ten male subjects, divided at random into two groups, performed distinct …

OBJECTIVES: The ability to maximally generate active muscle tension during resistance
training has been established to be a primary determinant for strength development. The …

The purpose of the current study was to compare the effect of 3 different rest intervals on
multiple sets of the bench press exercise performed with heavy vs. light loads. Sixteen …

Repeated activity of skeletal muscle causes a variety of changes in its properties: muscles
become weaker with intense use (fatigue), may feel sore and weak after repeated …
