The effect of eight weeks of resistance training and coenzyme Q10 supplement on interleukin 4 and 10 levels and functional indices of skilled softball players

The current study was aimed to investigate the effect of eight weeks of resistance training and coenzyme Q10 supplement on interleukin 4 and 10 levels and functional indices of skilled softball players.

Twenty females Softball players from Isfahan were selected by available sampling method and randomly assigned into two groups of 10 players (experimental group; Q10 + resistance training) and (control group; placebo + resistance training). The intervention consisted of eight weeks of Q10 supplementation (a 200 mg capsule) and 2 sessions per week of resistance training along with specialized softball exercises. Before and after the 8-week intervention, agility, speed, vertical jump, sit-ups, and hand-grip power were evaluated, as well as the blood sampling was obtained from athletes

Speed (P = 0.04 experimental; P = 0.02 control), agility (P = 0.03 experimental; P = 0.03 control), hand-grip power (P = 0.009 experimental; P = 0.01 control), sit-ups (P = 0.001 experimental; P = 0.003 control) and lactate dehydrogenase levels (P = 0.03 experimental; P = 0.03 control) significantly improved in both groups; however, Sargent's jump (P = 0.10 experimental; P = 0.89 control), creatine kinase (P = 0.67 experimental; P = 0.66 control), interleukin-4 (P = 0.32 experimental; P = 0.33 control) and interleukin-10 (P = 0.97 experimental; P = 0.08 control) did not alter in either group.

It appears that resistance training with Q10 supplementation along with specialized softball exercises is useful in developing some functional variables, especially abdominal endurance.
