AIM The research investigated, in a group of Greek-Roman wrestlers, whether the flexibility of the back and the hamstrings (MTF), the maximum strength of the forearms (HG) and the explosive elastic strength of the lower limbs are affected by circadian modifications comparing a specific training session at 10 a.m. ( and one at 6 p.m. METHODS Ten Greek-Roman wrestlers competing at national level (age 19±3 years, weight 76±14 kg, height 176±10 cm and 7±3 years of training) were involved. The measurements were performed at specific times: before warm-up (Pre-W); after warm-up (Post-W); after technical training (Post-At); after combat phase (Post-C); after cool-down (Post-D). RESULTS Evening training (ET): In the standing long jump test (SLF) the results were: 1) Pre-W vs Post-At (Friedman test, P <0.01, post-hoc, P <0.01, +8%), 2) Pre-W vs Post-C (Friedman test, P <0.01, P <0.01, + 9%). Morning training (MT): in the standing long jump test the same results were obtained as in the evening: 1) Pre-W vs Post-At (Friedman test, P <0.01, post-hoc, P<0.01, + 8%), 2) Pre-W vs Post-C (P<0.01, +9%). In the seat and reach test the results was: 1) Pre-W vs. Post-C (Friedman test, P <0.01, post-hoc, P<0,01, +15%); 2) Pre-W vs. Post-D (Friedman test, P <0.01, post-hoc, P<0,01, +13%). The comparison between ET and MT (Wilcoxon test) were: 1) Pre-W, SLF (ns ,-1,8%), FMT (ns ,-8,5%) and HG (ns, -6,4%); 2) Post-W, SLF (ns, -2,5%), FMT (ns, -0,4%) and HG (ns, +0,3%); 3) Post-At, SLF (ns, -2,4%), FMT (ns, -2,5%) and HG (ns , -10,9%); 4) Post-C, SLF (ns , -1,7%), FMT (ns, +2,9%), HG (P<0,01, -12%); 5) Post-D, SLF (ns, -1,6%), FMT (ns, +0,2%) and HG (ns, -7,5%). DISCUSSION/CONCLUSION In the HG the result indicates that athletes have to train at different times of the day to adapt to the competition time. The variation in FMT during MT stresses the importance of pre-competition warm-up.

Abstract
AIM The research investigated, in a group of Greek-Roman wrestlers, whether the flexibility of the back and the hamstrings (MTF), the maximum strength of the forearms (HG) and the explosive elastic strength of the lower limbs are affected by circadian modifications comparing a specific training session at 10 a.m. ( and one at 6 p.m. METHODS Ten Greek-Roman wrestlers competing at national level (age 19±3 years, weight 76±14 kg, height 176±10 cm and 7±3 years of training) were involved. The measurements were performed at specific times: before warm-up (Pre-W); after warm-up (Post-W); after technical training (Post-At); after combat phase (Post-C); after cool-down (Post-D). RESULTS Evening training (ET): In the standing long jump test (SLF) the results were: 1) Pre-W vs Post-At (Friedman test, P <0.01, post-hoc, P <0.01, +8%), 2) Pre-W vs Post-C (Friedman test, P <0.01, P <0.01, + 9%).
