Decreased NK lysis in MCFS and SCFS group compared to a non-fatigued control group. The percent lysis of NK cells in each group is represented above where the white bar represents the results from the non-fatigued control group and the black bar represents the SCFS group. Asterisk denotes statistical significance where P < 0.05 and data is represented as the mean ± SEM
