Abstract

Aim. To identify the relationship between central fatigue markers (Serotonin and testosterone) and anthropometric measures. Material and methods. 150 participants volunteered to undergo exercise fatigue protocol involving the calf muscles. Anthropometric measures were taken before the experiment and both central fatigue markers (Serotonin and testosterone) were recorded before and after the experiments. Results. There were extreme significant difference between BMI and serotonin level before the exercise t (148) = −8.410,

p = 0.00 and after the exercise t (148) = −7.915, p = 0,00. Also, there were extreme significant differences between BMI and testosterone level before the exercise t (148) = −8.512, p = 0.00 and after the exercise t (148) = −8.917, p = 0,00. There was extreme significant difference between WHR and serotonin level before the exercise t (148) = −6.744, p = 0.00 and after the exercise t (148) = −6.175,

p = 0,00. Also, there was extreme significant difference between WHR and testosterone level before the exercise t (148) = −7.62, p = 0.00 and after the exercise t (148) = −7.897, p = 0,00. Conclusions. Both BMI and WHR were significantly related to the change in serotonin and testosterone levels.
