Effects of different doses of physical activity on cardiorespiratory fitness among sedentary, overweight or obese postmenopausal women with elevated blood pressure: a randomized controlled trial.
CONTEXT Low levels of cardiorespiratory fitness are associated with high risk of mortality , and improvements in fitness are associated with reduced mortality risk . However , a poor underst and ing of the physical activity-fitness dose response relation remains . OBJECTIVE To examine the effect of 50 % , 100 % , and 150 % of the NIH Consensus Development Panel recommended physical activity dose on fitness in women . DESIGN , SETTING , AND PARTICIPANTS R and omized controlled trial of 464 sedentary , postmenopausal overweight or obese women whose body mass index ranged from 25.0 to 43.0 and whose systolic blood pressure ranged from 120.0 to 159.9 mm Hg . Enrollment took place between April 2001 and June 2005 in the Dallas , Tex , area . INTERVENTION Participants were r and omly assigned to 1 of 4 groups : 102 to the nonexercise control group and 155 to the 4-kcal/kg , 104 to the 8-kcal/kg , and 103 to the 12-kcal/kg per week energy-expenditure groups for the 6-month intervention period . Target training intensity was the heart rate associated with 50 % of each woman 's peak Vo2 . MAIN OUTCOME MEASURE The primary outcome was aerobic fitness assessed on a cycle ergometer and quantified as peak absolute oxygen consumption ( Vo2abs , L/min ) . RESULTS The mean ( SD ) baseline Vo2abs values were 1.30 ( 0.25 ) L/min . The mean ( SD ) minutes of exercising per week were 72.2 ( 12.3 ) for the 4-kcal/kg , 135.8 ( 19.5 ) for the 8-kcal/kg , and 191.7 ( 33.7 ) for the 12-kcal/kg per week exercise groups . After adjustment for age , race/ethnicity , weight , and peak heart rate , the exercise groups increased their Vo2abs compared with the control group by 4.2 % in the 4-kcal/kg , 6.0 % in the 8-kcal/kg , and 8.2 % in the 12-kcal/kg per week groups ( P<.001 for each vs control ; P for trend < .001 ) . There was no treatment x subgroup interaction for age , body mass index , weight , baseline Vo2abs , race/ethnicity , or baseline hormone therapy use . There were no significant changes in systolic or diastolic blood pressure values from baseline to 6 months in any of the exercise groups vs the control group . CONCLUSION In this study , previously sedentary , overweight or obese postmenopausal women experienced a grade d dose-response change in fitness across levels of exercise training .
