RESUMO
Background: Exercise training increases cardiovascular functional capacity and decreases myocardial oxygen demand at any level of physical activity. The aim of present study was to observe and compare the changes induced by isometric hand grip exercise on cardiovascular responses in young healthy male and female trained Volleyball and Basketball players with age and sex matched untrained controls. Methods: This study was carried out at Department of Physiology, J.S.S. Medical College and Hospital. Two hundred and forty (240) participants were included and were divided into trained Volleyball & Basketball players and healthy adult controls of both sex with 40 members in each category. Estimation of SBP, DBP, MAP and HR were carried out before, after and during various duration of exercise by adopting standard procedures Results: The mean SBP, DBP, MAP and HR at various durations for male subjects playing basketball, Volleyball and Control groups shows a significant increase (p<0.0001) in all the parameters at rest, during isometric HG exercise and at post exercise in untrained Control subjects. Conclusions: Exercise training increases cardiovascular functional capacity.
RESUMO
Background: Physical inactivity is recognized as a risk factor for coronary artery diseases. The aim of present study was to observe changes induced by isometric hand grip exercise on cardiovascular responses in young healthy trained female Volleyball and Basketball players. Methods: This study was carried out at Department of Physiology, J.S.S. Medical College and Hospital. Hundred and eighty (180) female participants were included and were divided into trained Volleyball & Basketball players and healthy adult controls of 60 each. Estimation of SBP, DBP, MAP and HR were carried out before, after and during various duration of exercise by adopting standard procedures Results: The mean SBP, DBP, MAP and HR at various durations for female subjects playing basketball, Volleyball and Control groups shows a significant increase (p<0.0001) in all the parameters at rest, during isometric HG exercise and at post exercise in untrained Controls compared with trained subjects. No significant difference was observed in the above said parameters at rest, during isometric HG exercise and at post exercise between Subjects and between volleyball and basketball players. Conclusions: Exercise leads to significant decrease in cardiovascular stress in trained individuals.
