the aim of the present study was to investigate the effect of two aerobic training programs with different intensities on some cardiovascular risk factors in young girls. for this purpose, 42 girls (mean age 20.59±1.46 years, height 160.29±4.75 cm, weight 59.23±8.82 kg, bmi 22.08±3.41 kg/m2, %bf 15.42±3.85 and vo2max 25.34±3.96 ml/kg/min) were voluntarily participated in this study and divided ...

the purpose of the present research was to examine the effect of one bout of exhaustive aerobic exercise with two different intensities on levels of serum mda in male smokers. for this purpose, 12 male smokers (age: 22.08 ±1.31 years, percent of body fat: 17.26 ±4.92% and body mass index: 23.21±2.96 kg/m2) were voluntarily selected and randomly participated in a crossover design in three situat...

abstract objective children suffering from cerebral palsy (cp), exhibit movement limitations and physiological abnormalities as compared to normal individuals. the objective of this study was to assess mechanical efficiency and certain cardiovascular indices before and after an exercise-rehabilitation program in children with dipelegia spastic cerebral palsy (experimental group) in comparison w...

OBJECTIVE To determine whether walking with a rollator by persons 75 years of age or older is of sufficient intensity to improve aerobic fitness. DESIGN A cross-sectional cohort study. SETTING University movement laboratory. PARTICIPANTS Fifteen subjects 75 years of age or older (mean age, 83.7 y) who could only walk by using a rollator. INTERVENTIONS Not applicable. MAIN OUTCOME MEAS...

This study assessed age-related changes in power and heart rate in 114 competitive male cyclists age 15-73 years. Participants completed a maximal Kingcycle ergometer test with maximal ramped minute power (RMPmax, W) recorded as the highest average power during any 60 s and maximal heart rate (HRmax, beats/min) as the highest value during the test. From age 15 to 29 (n = 38) RMPmax increased by...

conclusions in the children in this study, pacemaker accelerometers failed to meet physiological demands. results basal heart rates, maximal heart rates, and exercise tolerance were significantly lower in the children with pacemakers. age, sex, and body mass index had no effect on the heart rate slope during the exercise test. there was no significant difference between epicardial and endocardi...

in aim of this research was to investigate the effect of a decrease in the number of practice sessions and an increase in exercise intensity on aerobic and anaerobic power, body fat percentage, and body mass index. 80 subjects (average age: 20.2±1.53 years and height: 160.18±5.43cm) were divided into 4 groups (3 experimental groups and one control group). the experimental groups exercised with ...

The effects of chronic dynamic exercise on myocardial /3-adrenergic and muscarinlc cholinergic receptors and chronotropic sensitivity to isoproterenol were studied in 5 Yucatan miniswine. Right atrial and left ventricular biopsies, heart rate responses to isoproterenol, and maximal exercise treadmill testing were obtained before and after 10-19 weeks of treadmill running. Radioligand studies us...

The effects of chronic dynamic exercise on myocardial beta-adrenergic and muscarinic cholinergic receptors and chronotropic sensitivity to isoproterenol were studied in 5 Yucatan miniswine. Right atrial and left ventricular biopsies, heart rate responses to isoproterenol, and maximal exercise treadmill testing were obtained before and after 10-19 weeks of treadmill running. Radioligand studies ...
