PURPOSE The present study compared the effects of aerobic endurance training at different intensities and with different methods matched for total work and frequency. Responses in maximal oxygen uptake (VO2max), stroke volume of the heart (SV), blood volume, lactate threshold (LT), and running economy (CR) were examined. METHODS Forty healthy, nonsmoking, moderately trained male subjects were...

BACKGROUND It is unclear whether the common physical activity (PA) intensity descriptors used in PA guidelines worldwide align with the associated percent heart rate maximum method used for prescribing relative PA intensities consistently between sexes, ethnicities, age categories and across body mass index (BMI) classifications. OBJECTIVES The objectives of this study were to determine wheth...

Previously, the use of moderate-intensity continuous training (MICT) has generally been considered the most beneficial exercise treatment modality for the prevention/management of metabolic type disease. More recently, however, high-intensity interval training (HIIT) has emerged into the clinical setting as a potential alternative to traditional MICT in the management of such diseases, but the ...

This viewpoint debates the state-of-the-art research focusing on the optimal intensity of the exercise programs for inducing a sustained weight or fat-mass loss in overweight/obese people. In our demanding society, the most attractive messages in the popular press are those promising the best results in a short time. This might explain the emphasis given by media to those scientific articles th...

This study consists of two training experiments using a mechanically braked cycle ergometer. First, the effect of 6 wk of moderate-intensity endurance training (intensity: 70% of maximal oxygen uptake (VO2max), 60 min.d-1, 5 d.wk-1) on the anaerobic capacity (the maximal accumulated oxygen deficit) and VO2max was evaluated. After the training, the anaerobic capacity did not increase significant...

BACKGROUND Sedentary aging leads to adverse changes in vascular function and cardiac performance. We published improvements in vascular function with moderate intensity physical activity (PA) in continuous bouts. Whether moderate intensity PA also impacts cardiac structure and cardiovascular performance of the aging left ventricle (LV) is unknown. METHODS We recruited and analyzed results fro...

This study investigated the effects of high-intensity interval training (HIIT) vs. work-matched moderate-intensity continuous exercise (MOD) on metabolism and counterregulatory stress hormones. In a randomized and counterbalanced order, 10 well-trained male cyclists and triathletes completed a HIIT session [81.6 ± 3.7% maximum oxygen consumption (V̇o2 max); 72.0 ± 3.2% peak power output; 792 ± 9...

This study was designed to investigate the effect of exercise intensity on cardiorespiratory fitness and coronary heart disease risk factors. Maximum oxygen consumption (Vo(2 max)), lipid, lipoprotein, and fibrinogen concentrations were measured in 64 previously sedentary men before random allocation to a nonexercise control group, a moderate-intensity exercise group (three 400-kcal sessions pe...
