Serum lipoprotein(a) [Lp(a)] levels were measured before and after a 12-wk program of moderate-intensity endurance training. The training program consisted of walking and/or jogging, at least three sessions/wk of at least 30 min duration, at an intensity producing 60-85% HRmax reserve. Twenty-eight previously sedentary middle-aged Caucasian males matched for age, body mass, and body mass index (BMI) were randomly allocated to either an exercise (N=17, mean age +/-SEM = 51.57+/-1.25 yr) or a control (N=11, mean age +/-SEM = 50.0+/-1.15 yr) group. Pre- and post-training median Lp(a) levels, measured by immunoturbidimetric analysis, were not significantly different in either the exercise (pre 13.0, post 15.0 mg/dl) or the control subjects (pre 14.0, post 12.0 mg/dl). Kendall Rank correlation analysis revealed no significant relationship between the level of Lp(a) and any other variable in either group before or after training. In the exercisers, a significant increase was recorded in the estimated mean VO2may (pre 33.39+/-1.70, post 37.7+/-1.75 ml/kg/min). These data indicate that the level of Lp(a) was not influenced by a 12-wk program of moderate-intensity endurance training, and are consistent with previous reports suggesting that Lp(a) level is not altered by lifestyle factors.
