Effect of impact exercise on physical performance and cardiovascular risk factors.
INTRODUCTION Impact exercise is known to be beneficial for bones , but information regarding its effects on other health aspects is scarce . The aim of this study was to assess the effects of high-impact exercise on physical performance and glucose and lipid profiles . METHODS We performed a 12-month , population -based , r and omized controlled trial with 120 women ( 60 in the exercise group and 60 in the control group ; ages 35 - 40 yr ) . The exercise regimen comprised supervised , progressive , high-impact exercises two to three times per week and an additional home program .  Physical activity was continuously recorded using an accelerometer-based method and was analyzed as the daily number of impacts within five acceleration ranges between 0.3 and 9.2 g ( g = acceleration of gravity : 9.81 m x s(-2 ) ) . The changes in physical performance and in glucose and lipid profiles were determined . RESULTS Thirty-nine women in the exercise group and 41 women in the control group completed the study . Maximal oxygen uptake ( 6.2 vs 3.1 mL x kg(-1 ) x min(-1 ) ; P = 0.008 ) and countermovement ( 2.3 vs -0.3 cm ; P < 0.001 ) and static ( 1.4 vs -0.3 cm ; P = 0.004 ) jump heights increased significantly more in the exercise group than in the control group . Exercise training also decreased waist ( -1.1 vs 0.9 cm ; P = 0.048 ) and hip circumference ( -1.0 vs 1.1 cm ; P = 0.037 ) . Total cholesterol and LDL cholesterol decreased significantly more in women , with the highest number of impacts compared with the lowest quartile at intensities exceeding 1.1 g , with differences being up to -0.5 mM ( P = 0.005 ) . Additionally , poor baseline values predicted greater exercise effects . CONCLUSION The moderate-intensity exercise regimen , initially targeted at weight-bearing bones , improved cardiorespiratory fitness , speed-strength , and lipid profiles . In addition to bone health , impact exercise may be recommended for prevention of cardiovascular diseases
