Use of maximal aerobic power (VO2(max)) testing, which requires subjects to exercise to physiological limits, may deter eligible candidates from volunteering for trials and may also be contraindicated in patients suffering from various medical illnesses. An alternative to maximal testing is submaximal testing. The Aerobic Power Index, which represents the ...

BACKGROUND: Aerobic endurance exercise has been shown to improve higher cognitive functions such as executive control in healthy subjects. We tested the hypothesis that a 30-minute individually customized endurance exercise program has the potential to enhance executive functions in patients with major depressive disorder. METHOD: In a randomized within-subject study ...

In the past, patients with neuromuscular diseases were advised not to exercise because of the fear that too much exercise might produce "overuse weakness." No controlled studies have demonstrated that the phenomenon of overuse weakness actually exists. Most studies of exercise training in patients with neuromuscular disease, despite methodologic limitations, ...

A fundamental assumption of the aerobic capacity model for the evolution of endothermy is that basal (BMR) and peak (PMR) metabolic rates are functionally linked at the intraspecific level. The purpose of this study was to use the nine-banded armadillo Dasypus novemcinctus as a model to test this assumption. Measurements ...

Many similarities exist between the key characteristics of muscular metabolism in marine invertebrates and those found in vertebrate striated muscle, even though there are important phosphagens and glycolytic end products that differ between groups. Lifestyles and modes of locomotion also vary extremely among invertebrates thereby shaping the pattern of exercise ...

Three mussel groups differing in mean multilocus heterozygosity (MLH) were used to examine the MLH-fitness relationship. Mussels were submitted to aerobic and anaerobic stressful conditions in the laboratory, and their LT(50) was measured. Mortality was not random in two of the three groups and affected the homozygous individuals more. This ...

PURPOSE: Recent guidelines have recommended the use of a percentage of oxygen uptake reserve (VO2R) for prescribing aerobic exercise intensity for cardiac patients. Moreover, these guidelines suggest that a threshold intensity may exist, below which no improvement in peak oxygen uptake (VO2peak) occurs. The purpose, therefore, was to translate the ...
