  • Description: To examine the effects of eccentric and concentric progressive resistance training on muscle torque–angle relationship, 30 young adults were randomly allocated into three groups of 10, control (CTL), eccentric training (ECC) and concentric training (CON). The ECC and CON groups performed seven sessions over 3 weeks of progressive resistance training of the right hamstrings muscle, using a standard barbell and a leg curl machine. Torque–angle relationship was measured before and 4, 11 and 18 days after the end of training. Voluntary isometric torque was recorded at seven test angles, with the subject prone (20–80°; 0° is full extension). In the CON group, the angle of peak isometric torque increased from 46.0±5.2° pre‐training to 53.0±14.9° on day 4 following training (P<0.05). In the ECC group, peak torque was increased over baseline on days 4 and 11 post‐training, particularly at extended knee angles (P<0.05). The angle at which peak torque occurred was decreased on day 4 (50.0±8.2° pre‐training, 29.0±7.4° on day 4) and on day 11 (both P<0.01), but was similar to baseline 18 days after training. ECC therefore induced a temporary change in torque–angle relationship.
