Thyrotoxic periodic paralysis (TPP), a disorder most commonly seen in Asian men, is characterized by abrupt onset of hypokalemia and paralysis. The condition primarily affects the lower extremities and is secondary to thyrotoxicosis. The underlying hyperthyroidism is often subtle causing difficulty in early diagnosis. Factors like high-carbohydrate meal exercise, steroid, ...

Inorganic nitrate has been shown to reduce oxygen cost during exercise. Since the nitrate-nitrite-NO pathway is facilitated during hypoxia, we investigated the effects of dietary nitrate on oxygen consumption and cardiovascular responses during apnea. These variables were measured in two randomized, double-blind, placebo-controlled, crossover protocols at rest and ergometer exercise ...

The United States Department of Health and Human Services disseminated physical activity (PA) guidelines (PAGs) for Americans in 2008. The guidelines are based on appropriate quantities of moderate-to-vigorous aerobic PA and resistance exercise (RE) associated with decreased morbidity and mortality risk and increased health benefits. However, increases in PA levels ...

Background: Hyperammonemia during rest periods is a dysfunction in heart failure (HF). The low formation of ammonia during exercise reflects an inefficiency of purine metabolism. Hyperkalemia in response to physical exercise is common in HF and may contribute to a contractile inefficiency in type II fibers, leading to early fatigue. ...

The equine superficial digital flexor tendon (SDFT) is a frequently injured structure that is functionally and clinically equivalent to the human Achilles tendon (AT). Both act as critical energy-storage systems during high-speed locomotion and can accumulate exercise- and age-related microdamage that predisposes to rupture during normal activity. Significant advances in ...
