Strength and power training did not modify cardiovascular responses to aerobic exercise in elderly subjects.
Resistance training increases muscle strength in older adults , decreasing the effort necessary for executing physical tasks , and reducing cardiovascular load during exercise . This hypothesis has been confirmed during strength-based activities , but not during aerobic-based activities . This study determined whether different resistance training regimens , strength training ( ST , constant movement velocity ) or power training ( PT , concentric phase performed as fast as possible ) can blunt the increase in cardiovascular load during an aerobic stimulus . Older adults ( 63.9 ± 0.7 years ) were r and omly allocated to : control ( N = 11 ) , ST ( N = 13 , twice a week , 70 - 90 % 1-RM ) and PT ( N = 15 , twice a week , 30 - 50 % 1-RM ) groups . Before and after 16 weeks , oxygen uptake ( VO(2 ) ) , systolic blood pressure ( SBP ) , heart rate ( HR ) , and rate pressure product ( RPP ) were measured during a maximal treadmill test . Resting SBP and RPP were similarly reduced in all groups ( combined data = -5.7 ± 1.2 and -5.0 ± 1.7 % , respectively , P < 0.05 ) . Maximal SBP , HR and RPP did not change . The increase in measured VO(2 ) , HR and RPP for the increment in estimated VO(2 ) ( absolute load ) decreased similarly in all groups ( combined data = -9.1 ± 2.6 , -14.1 ± 3.9 , -14.2 ± 3.0 % , respectively , P < 0.05 ) , while the increments in the cardiovascular variables for the increase in measured VO(2 ) did not change . In elderly subjects , ST and PT did not blunt submaximal or maximal HR , SBP and RPP increases during the maximal exercise test , showing that they did not reduce cardiovascular stress during aerobic tasks
