exercise conditioning was effective in producing myocardial hypertrophy , as reflected by an increase in heart weight ( 1.179 +/- 0.022 vs. 1.031 +/- 0.020 g , p less than 0.001 ) and heart weight-to-body weight ratio ( 3.29 +/- 0.06 vs. 2.77 +/- 0.05 x 10 ( -3 ) , p less than 0.001 ) but no difference in body weight .
