BACKGROUND Running an ultramarathon has been shown to have a transient negative effect on right ventricular (RV) and left ventricular (LV) function. Additionally, recent findings suggested that ultraendurance athletes may be more at risk of developing a RV cardiomyopathy. The standard echocardiographic assessment of RV function is problematic; however, the(More)
The health benefits of exercise are well established. However, the relationship between exercise volume and intensity and health benefits remains unclear, particularly the benefits of low-volume and intensity exercise. The primary purpose of this investigation was, therefore, to examine the dose–response relationship between exercise volume and intensity(More)
Physical activity is beneficial for many chronic conditions. However, activity levels of Native Americans are not well known. This systematic review investigated if Native American populations achieve the recommended physical activity levels, compared current and past activity levels, and assessed the ability of exercise training programmes to improve(More)
UNLABELLED Though historically rare, Aboriginal individuals continue to experience greater levels of cardiovascular disease than the general Canadian population. Increasing evidence indicates rising sedentary behaviors from the traditional healthy and active lifestyles of this population. OBJECTIVE This investigation aimed to examine the health benefits(More)
Recommendations for physical activity during pregnancy have progressed significantly in the last 30 years and continue to evolve as an increasing body of scientific evidence becomes available. In addition, there is an increasing number of women who wish to either maintain physical fitness levels during the prenatal period or initiate exercise for a(More)
We aimed to investigate the effects of a single session of prolonged strenuous exercise (PSE) on arterial stiffness by measuring pulse wave velocity (PWV) before and after competition in an ultramarathon. A total of 20 routine ultramarathon competitors (UM) completed baseline and postrace evaluation of central PWV (cPWV), upper-limb PWV (uPWV), and(More)
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 exercise session. Pulse transit time was evaluated between(More)
BACKGROUND AND OBJECTIVE Hypertension and obesity are major contributors to cardiovascular disease, and the relationship between these conditions is known to vary among ethnicities. However, this relationship has not previously been examined in aboriginal populations. The present investigation aimed to identify and compare this relationship among white (n =(More)
Cardiometabolic risk is a growing concern in Western society in which rates of cardiovascular disease, diabetes, and obesity are on the rise. Aboriginal populations currently experience unequal burdens of these chronic conditions. However, limited information regarding the experience of cardiometabolic risk among Métis populations is available. This review(More)
