In this study, 10 adult males were randomly selected as the ingestion group and the control group. The subjects were the first people to participate in the crossfit for a total of 6 weeks, and the following conclusions were obtained.

1. In the fitness factors, the intake group showed statistically significant difference in all fitness factors. The control group showed significant differences only in left muscle strength(p<.01), right muscle strength(p<.05), left muscle endurance(p <.05) and power(p<.01).

2. Changes in body fat percentage showed a decrease in both groups, but there was a statistically significant difference only in the intake group(p <.01). 3. In the change of blood lactate level, the intake group showed a statistically significant difference(p<.01) after the experiment, In contrast, the control group had an increase in blood lactate but it showed a statistically significant difference(p<.05).

4. The decrease in blood lactate levels between the two groups was statistically significant(p<.05) as the intake group decreased and the control group increased.

Taking these conclusions together, we examined the effect of exercise on improved physical fitness, decreased body fat percentage and decreased blood lactate.
