A recent study published in Medicine and Science in Sports and Exercise may help explain the beneficial impact of exercise on depression. The researchers measured the effect of exercise on the level of tryptophan in men aged 57-70. The amino acid tryptophan is an important precursor for the manufacture of serotonin. The researchers surmised that serotonin levels would be higher in elderly individuals who exercise regularly, and that is exactly what they found based on changes in tryptophan metabolism.. There was a corresponding increase in serotonin synthesis during exercise and serotonin remained elevated during post-exercise recovery. This study elucidates an important reason for the positive mental benefits derived from exercise.
