Effects of resistance training on physical performance in high-level 800-meter athletes: a comparison between high-speed resistance training and circuit training
This study compared the effects of two resistance training programs during 25 weeks on physical performance and hormonal response in high-level 800 m athletes. Thirteen male athletes (800 m personal best: 1:43-1:58 min:ss) were divided into 2 groups: highspeed resistance training group (RTG) (n = 6)...

| Sumario: | This study compared the effects of two resistance training programs during 25 weeks on physical performance and hormonal response in high-level 800 m athletes. Thirteen male athletes (800 m personal best: 1:43-1:58 min:ss) were divided into 2 groups: highspeed resistance training group (RTG) (n = 6) and circuit training group (CTG) (n = 7). Three tests (T1, T2 and T3) including sprint and 800 m running, strength exercises and blood hormones samples were carried out. Both groups showed improvements in 800 m performance (RTG: likely positive, 80/20/0%; CTG: very likely positive, 98/2/0%), however, RTG showed an additional improvement in 200 m (likely positive, 85/15/0%), countermovement jump (very likely positive, 98/2/0%), and squat (likely positive, 91/9/0%), whereas CTG reached likely positive (88/11/1%) effects in CMJ and unclear/possibly negative effects in the rest of the strength variables analyzed. Concerning hormones, RTG resulted in a likely increase (83/15/3%) in testosterone from T1 to T3, and CTG showed a likely increase (79/17/4%) in cortisol from T2 to T3, remaining the rest of the hormones analyzed unclear. These results suggest that a resistance training characterized by high-speed and low-volume produced better improvements in both strength and running performance than a circuit training, accompanied by little changes in the hormonal response.
