the aim of this study was to investigate the effect of moderate rhythm of music on perceived exertion and heart rate during different intensities of endurance training in young male athletes. 10 male athletic students (mean + sd age 21.6±2.60 years) were voluntarily selected. the present study was conducted in a crossover design with and without music. the results showed no significant differen...

OBJECTIVES We sought to determine a generalized equation for predicting maximal heart rate (HRmax) in healthy adults. BACKGROUND The age-predicted HRmax equation (i.e., 220 - age) is commonly used as a basis for prescribing exercise programs, as a criterion for achieving maximal exertion and as a clinical guide during diagnostic exercise testing. Despite its importance and widespread use, the...

AIM Intervention fidelity refers to the degree to which an experimental manipulation has been implemented as intended, but simple, robust methods for quantifying fidelity have not been well documented. Therefore, we aim to illustrate a rigorous quantitative evaluation of intervention fidelity, using data collected during a high-intensity interval training intervention. DESIGN Single-group mea...

Maximal bicycle ergometer exercise in an asymptomatic male population, aged 40-65 years, revealed 63 subjects with 'ischaemic' ST changes. The work intensity at the time of appearance of this change was expressed as actual heart rate as a per cent ofmaximum heart rate, and oxygen uptake as a per cent ofmaximal oxygen uptake. If the exercise had been stopped at a target heart 'rate of 85 per cen...

Relevance. Сardiovascular status could be assessed by maximal aerobic capacity (VO2max) through direct analysis of the gases involved in pulmonary ventilation and monitoring fluctuations intervals between beats over time as heart rate variability. The aim study was to investigate relationship VO2max variability young adults. Materials Methods. A total 100 adults ages 18 25 were included observa...
