Habitual physical activity participation is widely accepted to be a safe and effective method for managing cardiovascular and metabolic disease risk factors. However, engagement in physical activity has the potential to trigger cardiovascular events, especially when the activity is of vigorous inten...

It is well established that habitual aerobic exercise training is associated with an increase in arterial compliance. A small number of studies have examined the effects of an acute bout of aerobic exercise on measures of arterial compliance, with the conclusion that short duration exercise leads to...

Abstract There is increasing evidence that select forms of exercise are associated with vascular changes that are in opposition to the well-accepted beneficial effects of moderate intensity aerobic exercise. Objective To determine if alterations in arterial stiffness occur following eccentrically...

The cycling leg of a triathlon imposes unique physiological and biomechanical demands on athletes compared with cycle racing. By recognizing these differences, athletes and coaches can use training practices to optimize adaptations according to the principle of specificity. The primary emphasis is o...

Physical activity (PA) is one of the most powerful treatment options for persons with prediabetes or diabetes. However, some elevation in risk occurs with increased PA, at least initially, and certain precautions need to be made to lower these risks, particularly if these persons are unaccustomed to...
