چکیده:
The purpose of the present study was to investigate the effect of endurance (ET), resistance (RT) and concurrent
training (CT) on plasma levels of visfatin, insulin, glucose and insulin resistance of non-athlete men with Obesity. It
was a semi-experimental study. Thirty six men [age: 21.48 (0.25), and BF%: 27.39 (0.52)], voluntarily participated
in this study after public announcement in university. Main inclusion and exclusion criteria was healthy (no physical
illness and inability), obesity [based on WHO's definition body fat percentage (BF%) of over 25] and non-athlete
(without regular training during week). They were randomly divided into three groups (n=12) for ET, RT and CT.
For 8 weeks (3sessions/week), the candidates participated in ET (25-40 min at 65-85% of maximum heart rate), RT
(5exercises, 6sets, intensity: 50-80% of one repetition maximum, volumes: 5, 8 and 12repetitions) and CT (one or a
half-term ET and then RT with 3 sets). Blood samples were taken 48 h before the first training session and 48 h after
the last training session. The BF% in ET was significantly less than that in RT (p0.01), and in CT, it was less than
that for both ET and RT (p0.01). Plasma visfatin only, in CT was significantly less than that in RT (p0.01). Plasma
insulin levels in CT were significantly higher than that in ET and RT (p0.01). Plasma glucose levels in CT were
less than that in ET and RT, significantly (p0.01). Insulin resistance only in CT was less than that in ET
significantly (p0.01). In general, the present study showed that maybe, CT have more effect on the body
composition, glucose metabolism and insulin resistance adjustment, which can be effective in preventing obesity and
adjusting adipocytokines such as visfatin.

ABSTRACT The purpose of the present study was to investigate the effect of endurance (ET), resistance (RT) and concurrent training (CT) on plasma levels of visfatin, insulin, glucose and insulin resistance of non-athlete men with Obesity.
(2011) in a study reported the effect of 12 weeks of combined training [3 sets of 10 repetition maximum (10RM) resistance exercise as well as aerobic exercise at an intensity of 60-70% of their heart rate reserve (HRR)] on visfatin and factors of metabolic syndrome in middle-aged obese women.
(2010) showed that doing a rapid session of anaerobic running training (7 sets of 10-s running of 35 x 6 m with one minute rest between sets) in 60 young men with high physical fitness was associated with a significant increase in plasma visfatin levels and insulin, blood glucose concentration and insulin resistance index immediately after training (32).
So, the purpose of the present study was to compare 8 weeks of endurance, resistance and combined training on levels of plasma visfatin, insulin, glucose, and insulin resistance in young non-athlete men with obesity.
The results of the present study showed that the plasma visfatin levels were significantly different in obese inactive individuals after 8 weeks of training with different protocols of resistance, endurance and concurrent training."
