Functional capacity is the physical ability to perform a defined task. In humans it can be evaluated by using exercise testing, for instance sub-maximal exercise tests. Walking tests are widely used variations of submaximal exercise tests and in human medicine are considered to be realistically related to daily physical activity and prognosis in patients with heart failure. The aim of this stud...

The coefficient of repeatability (COR), expressed as 2-SD of differences, was calculated between two measurements of oxygen consumption (V O2), heart rate (HR) and rating of perceived exertion (RPE) during ergometer cycling by men. The two sets of measurements were performed 5 to 6 weeks apart. Nineteen healthy men performed an incremental maximal exercise test on an ergometer cycle. The load s...

Objectives: Heart rate recovery (HRR) after exercise is clinically important as a predictor of mortality. In addition, HRR an indicator cardiac autonomic activity, since increased vagal activity and diminished sympathetic return the heart to resting conditions exercise. The previous attempts model using polynomial, first-order second-order modelling have produced mixed results. this study, we h...

Abstract This study aimed to determine whether the recently developed Flow Motion Technology ® roller-ski prototype could improve indicators of performance during sub-maximal and maximal cross-country roller skiing. Thirteen national international skiers completed 2 experimental trials: 1 with activated, allowing a rocking motion between foot ski binding, fixed in traditional manner. Each trial...
