Purpose: The purpose of this study was to investigate if endurance athletes, sustaining their normal endurance training, experience attenuated adaptations to strength training compared to untrained individuals. Methods: Eleven non-strength-trained female endurance athletes (E + S) added 11 weeks of strength training to their normal endurance training (5.1 ± 1.1 h per week), and 10 untrained women (S) performed the same strength training without any endurance training. The strength training consisted of four leg exercises [3 × 4 − 10 repetition maximum (RM)], performed twice a week for 11 weeks. Results: E + S and S displayed similar increases in 1RM one-legged leg press (E + S 39 ± 19%, S 42 ± 17%, p < 0.05), maximal isometric torque in knee extension (E + S 12 ± 11%, S 8 ± 10%, p < 0.05) and lean mass in the legs (E + S 3 ± 4%, S 3 ± 3%, p < 0.05). However, S displayed superior increases in peak torque in knee extension at an angular velocity of 240° sec−1 (E + S 8 ± 5%, S 15 ± 7%, p < 0.05) and maximal squat jump height (E + S 8 ± 6%, S 14 ± 7%, p < 0.05). Conclusions: In this study, concurrent training did not impair the adaptations in the ability to develop force at low contraction velocities or muscle hypertrophy. However, concurrent training attenuated strength training-associated changes in the ability to develop force at higher muscular contraction velocities.
