We evaluated gender-specific effects of two types of undergarments on exercise-induced physiological and psychological stress and subsequent recovery in cold conditions for male and female participants. Ten healthy men and eleven healthy women (25.0 ± 1.5 versus 23.4 ± 1.2 years old, respectively) completed the experimental session twice with two different types of undergarments: polyester or m...

Background: Increased arterial stiffness (AS) following exercise may be associated with acute cardiovascular events. High-intensity play an important role in increase AS after exercise. Objectives: This study aimed to examine the effect of reduced-exertion high-intensity interval training (REHIT) on among individuals insufficient physical activity compared that normal-weight and overweight/obes...

The rating of perceived exertion (RPE) was assessed at power outputs (PO) corresponding to 30%, 60% and 90% of predicted maximal oxygen uptake (VO2 max) on a cycle ergometer in 30 adolescent schoolboys (age range 15-17 years). Analysis of correlations (r) for heart rate (HR):PO (r = 0.74 p less than 0.01) and rating of perceived exertion (RPE): HR (r = 0.74 p less than 0.01) were similar to val...

This study examined the effects of 3 days of estrogen supplementation (ES) on thermoregulation during exercise in premenopausal (20-39 yr) adult women during the follicular phase of the menstrual cycle. Subjects (11 control, 10 experimental) performed upright cycle ergometer exercise at 60% of maximal O2 consumption in a neutral environment (25 degreesC, 30% relative humidity) for 20 min. Subje...

Symptom-limited maximal oxygen intake (VO SL) and electrocardiographic responses to multistage treadmill test were determined before and after 3 months of physical training in 14 patients with coronary heart disease. Six patients also had hemodynamic studies done at several submaximal work loads in the upright position before and after training. S-T-segment responses were measured by computer a...
