The purpose of this study was to evaluate fitness and health adaptations from a training program riding all-terrain vehicles (ATV) and off-road motorcycles (ORM) as the exercise stimulus. Participants (n = 58) were randomized to a control group (n = 12) or one of four experimental groups; 2 days/wee...

We aimed to compare the Finapres system, which is designed for accurate intra-arterial amplitude measurement, to the Caretaker system, which is designed for temporal accuracy of intra-arterial measurement, in regard to measurement of pulse transit time (PTT) at baseline and following an endurance ex...

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...

There is a growing interest in training for and competing in race distances that exceed the marathon; however, little is known regarding the vascular effects of participation in such prolonged events, which last multiple consecutive hours. There exists some evidence that cardiovascular function may ...

Recent reports that habitual marathon runners demonstrate higher levels of stiffness and cardiovascular risk factors have been of great interest to the medical and scientific community. Ultra-marathon running, that is any distance >42.2 km, is increasing in popularity; however, little is known regar...

Conditions such as stroke and spinal cord injury (SCI) reduce the ability to activate muscle and produce movement, typically affecting a patient’s functional capacity and ability to carry out the tasks of daily living. Mobility limitations increase the risk of other avoidable chronic conditions su...

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...

Altered autonomic function has been identified following ultra-endurance event participation among elite world-class athletes. Despite dramatic increases in recreational athlete participation in these ultra-endurance events, the physiological effects on these athletes are less known. This investigat...

Traditionally, exercise was advised with caution or not recommended for pregnant women. Women active before pregnancy were advised by physicians to reduce their habitual exercise levels, while previously inactive women were advised to refrain from initiating exercise programs.1 However, guidelines f...

Exercise-induced cardiovascular (CV) events, particularly sudden cardiac death (SCD), attract considerable media attention in the context of the safety of exercise for the general population. As a result, concern about the safety of exercise participation is a common topic during routine office chec...

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...

The aim of this research is to provide a comprehensive understanding of the physiological fitness and health-related effects of participation in habitual recreational off-road vehicle riding (all-terrain vehicle (ATV) and off-road motorcycle (ORM)) as an alternative form of physical activity (PA).

There is a paucity of research examining the 6-minute walk test (6MWT) in young to middle-aged healthy individuals, and little is known about the utility of the 6MWT for predicting aerobic fitness. Purpose: 1) To characterize the aerobic demand of the 6MWT in a group of healthy working-aged adults; ...
