introduction: good functional capacity has a high negative predictive value (npv) in patients with known or suspected coronary artery disease (cad) similar to a normal gated myocardial perfusion imaging (gmpi). aim of this study was to evaluate npv of functional capacity during treadmill exercise in patients with normal gmpi in pakistani population. methods: this was a prospective study which ...

This study was designed to quantify the daily distribution of training intensity in a group of well-trained junior cross-country skiers and compare the results of three different methods of training intensity quantification. Eleven male athletes performed treadmill tests to exhaustion to determine heart rate and VO2 corresponding to ventilatory thresholds (VT1, VT2), maximal oxygen consumption ...

OBJECTIVE Heart rate recovery (HRR) is an independent prognostic indicator for cardiovascular disease (CVD) and all-cause mortality in healthy men. We examined the association of HRR to CVD-related and all-cause mortality in men with diabetes. RESEARCH DESIGN AND METHODS In this cohort study we examined 2,333 men with documented diabetes (mean age 49.4 years) that had baseline 5-min HRR measu...

It has been suggested that genetic variation in the angiotensin-converting enzyme (ACE) gene is associated with physical performance. We studied the association between the ACE insertion (I)/deletion (D) polymorphism and several fitness phenotypes measured before and after 20 wk of a standardized endurance training program in sedentary Caucasian (n = 476) and black (n = 248) subjects. Phenotype...

To quantify the rotational demands of elite female field hockey with respect to position. Twenty-eight (n = 28) international players were recruited during 2018–2020 seasons. Players monitored GPS technology and heart-rate monitors. Methods: Activity was categorised into total distance (m), relative (m·min−1), high-speed (m; 16 km∙h−1), max velocity (km·h−1), percentage maximal (%Vmax). Physiol...
