We examined the effect of training history on the load-power relationship in vertical jumping (VJ) by employing external loads ranging from -30% to +30% body weight (BW). Based on previous findings, we hypothesized that (1) the maximum dynamic output (power production and momentum generation) would be within the tested loading ...

Elite sport requires high-volume and high-intensity training that inevitably induces neuromuscular fatigue detrimental for physical performance. Improving recovery processes is, therefore, fundamental and to this, a wide variety of recovery modalities could be proposed. Among them, neuromuscular electrical stimulation is largely adopted particularly by endurance-type and team sport athletes. This ...

PURPOSE:: Three-to-five consecutive days of endurance exercise can protect the heart against an ischemia-reperfusion (IR) insult. However, the mechanism(s) responsible for this exercise-mediated cardioprotection remain unknown. Given the important role that mitochondria play in IR-induced cardiac myocyte injury, we hypothesized that exercise training promotes cardioprotection, at least in part, by ...

Abstract Background. Chronic heart failure (CHF) is associated with increased inflammation, and exercise training has in some studies been shown to have anti-inflammatory effect, although controversies exist. We investigated the effects of exercise training in CHF patients on markers of inflammation, and further explored any association between inflammation and the ...

The vascular endothelium plays a key role in arterial wall homeostasis by preventing atherosclerotic plaque formation. A primary causal factor of endothelial dysfunction is the reactive oxygen species. Aerobic exercise is ascribed as an important adjuvant therapy in endothelium-dependent cardiovascular disease. However, little is known about the effects of concurrent ...

Endurance and strength training are established as distinct exercise modalities, increasing either mitochondrial density or myofibrillar units. Recent research, however, suggests that mitochondrial biogenesis is stimulated by both training modalities. To test the training-"specificity" hypothesis, mitochondrial respiration was studied in permeabilized muscle fibers from 25 sedentary adults after endurance (ET) ...

Post-exercise hypotension (PEH), the reduction of blood pressure (BP) after a single bout of exercise, is of great clinical relevance. As the magnitude of this phenomenon seems to be dependent on pre-exercise BP values and chronic exercise training in hypertensive individuals leads to BP reduction; PEH could be attenuated in ...
