The aim of the present study was to compare the serum serotonin level and some physical fitness factors in the active elderly in Qom city. The sample comprised of male elderly over 60 years old in Qom city who were assigned to aerobic (n=15), weight training (n=15), zurkhaneh (n=15) and control (n=15) groups. In order to assess physical fitness, 4 factors including balance (single leg balance test), muscle endurance (swimming on hand), flexibility (Wells flexibility test) and power (Sargent jump) were studied. Blood serotonin was measured with ELISA test. Data were analyzed using one-way ANOVA (P<0.05). The results showed that serum serotonin levels were higher in active groups than control group (P<0.05) but there were no significant differences in blood serotonin level among active groups (P>0.05). The level of physical fitness in active subjects was better than the control group. In addition, weight training group showed a higher level of fitness in balance and muscle endurance tests (P<0.05). With regard to the results, it can be noted that sport especially weight training can have a significant effect on increasing serum serotonin level and physical fitness in the elderly.
