The aim was to study the suitability of the heart rate variability (HRV) spectral parameters for evaluations of bicycle ergometry results in coronary heart disease (CHD) patients. Methods. Our study included 243 male CHD patients aged 49±8 years. The coronary atherosclerosis was assessed by coronary angiography. The results of bicycle ergometry, Doppler echocardiography and HRV spectral analysi...
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...
This study aimed to investigate the acute effects of two strength-training protocols on the neuromuscular and cardiorespiratory responses during endurance exercise. Thirteen young males (23.2 ± 1.6 years old) participated in this study. The hypertrophic strength-training protocol was composed of 6 sets of 8 squats at 75% of maximal dynamic strength. The plyometric strength-training protocol was...
We measured physiological responses of elderly recreational skiers of different fitness and skiing abilities. Six subjects (mean age: 61.2 ± 4.6 yrs; Wt: 76.8 ± 15.6 kg; Ht: 1.69 ± 0.10 m; BMI: 26.9 ± 5.0) were tested in a laboratory and during 30 and 75 min of recreational downhill skiing. Oxygen uptake (VO2), heart rate (HR), blood lactate (LA) concentration, and diastolic (DBP) and systolic ...
Introduction: In some jobs, physical activity can be done in high noise pollution that can affect the heart rate. The aim of this study was to investigate the effects of noise exposure and physical activity on heart rate in the hot and humid conditions. Materials and Methods: This experimental study was performed on 14 healthy men in hot and humid climatic chamber (35 °C, 75% RH). ...
