Natural killer cell cytotoxic activity (NKCA) and the proportion of circulating natural killer (NK) cells were compared in 10 weight trainers versus 10 sedentary controls. Height, weight, and percent body fat did not differ significantly between the two groups. The average subject in the weight training group was able to squat 1.8 times his body weight, lifted weight more than 6 hours a week, and had been a weight trainer for nearly 9 years. NKCA did not differ between the weight training and control groups (166 ± 33 vs. 155 ± 27 lytic units, respectively), and the proportion of NK cells was the same (15.1 ± 1.9% vs. 15.1 ± 1.3%, respectively). The results of this cross-sectional study of long-term weight trainers and sedentary controls indicate no significant differences in NKCA. The two groups did not differ in the distribution of lymphocytes or natural killer cells, lending strength to this conclusion.
