Mitochondria form a reticulum in skeletal muscle. Exercise training stimulates mitochondrial biogenesis, yet an emerging hypothesis is that training also induces qualitative regulatory changes. Substrate oxidation, oxygen affinity and biochemical coupling efficiency may be differentially regulated with training and exposure to extreme environments. Threshold training doses inducing mitochondrial up-regulation remain ...

Introduction: Postural tachycardia syndrome (POTS) is associated with exercise intolerance, hypovolemia and cardiac atrophy, which may contribute to reduced stroke volume and compensatory exaggerated heart rate (HR) increases. Acute volume loading with intravenous saline reduces HR and improves orthostatic tolerance and symptoms in POTS, but its effect on exercise capacity ...

Cardiotoxicity is a common side effect for cancer patients treated with doxorubicin (DOX). We tested the hypothesis that low intensity aerobic exercise concomitant with DOX treatment would offset DOX-induced cardiotoxicity while also improving the therapeutic efficacy of DOX on tumor progression. B16F10 melanoma cells (3x10(5)) were injected subcutaneously into the ...

Traditional strength training with 80% of one-repetition maximum (1RM) utilizes 2- to 5-minute rest periods between sets. These long rest periods minimize decreases in volume and intensity, but result in long workouts. Performing upper-body exercises during lower-body rest intervals may decrease workout duration, but may affect workout performance. Therefore, the ...

Background: Proper acute management of exercise-associated hyponatremia (EAH) has been known for decades, yet this information has not been uniformly implemented. Since treatment of EAH with isotonic fluids can result in delayed recovery and death, it is important that proper acute management in the field and hospital be utilized. Case ...

In this review, we explore the association among physical activity, cardiorespiratory fitness, and exercise on gray matter volume in older adults. We conclude that higher cardiorespiratory fitness levels are routinely associated with greater gray matter volume in the prefrontal cortex and hippocampus and less consistently in other regions. We also ...
