Abstract Sexual dimorphism exists in numerous aspects of exercise physiology. One area that has long been debated is the potential of sex differences in cardiac structure and function. Anthropometric differences exist between males and females, and the relationship between absolute body size and cardiac structure dictate that men typically have ...

Hypertrophic cardiomyopathy (HCM), the most common genetic cardiac disorder, is frequently caused by mutations in MYBPC3, encoding cardiac myosin-binding protein C (cMyBP-C). Moreover, HCM is the leading cause of sudden cardiac death (SCD) in young athletes. Interestingly, SCD is more likely to occur in male than in female athletes. However, ...

There is a view that exercise is less effective for weight loss in women compared with men. This systematic review examines the evidence for sex-based differences in the effect of exercise on body weight. We hypothesize that, when energy expenditure is equivalent, there will be no evidence for sex differences ...

Cough, exercise, and sex headaches are underrecognized distinct but related syndromes, triggered by rapid rises in intra-abdominal pressure. All may occur as a manifestation of a possible underlying, symptomatic etiology, and additional diagnostics should typically be pursued to rule out serious causes. Cough headaches may be more common in certain ...

High doses of anabolic androgenic steroids (AAS) impair the cardioprotective effects of exercise against ischemia/reperfusion (I/R) insult, possibly through cellular redox imbalance. Here, the effect of nandrolone decanoate (DECA) treatment on heart redox metabolism was investigated during I/R in sedentary and exercised rats. DECA treatment significantly reduced superoxide dismutase and ...

Decreased physical performance is a well-known consequence of rapid ascent to high altitude. Hypoxic pulmonary vasoconstriction (HPV) potentially limits cardiac output and systemic blood flow, thus preventing successful adaptation to rapid ascent. We hypothesized that pharmacological enhancement of the heart rate with theophylline, combined with reversal of HPV via endothelin ...
