Brief Summary

Mode specificity of eccentric and concentric isokinetic training have been examined in previous studies but with conflicting results. The present study aimed to examine the mode-specific effects of eccentric and concentric isokinetic training of hamstring muscle at slow angular velocity on eccentric peak torque of hamstring (PTecc), concentric peak torque of quadriceps (PTcon), acceleration time of hamstring (AThams) and quadriceps (ATquad), deceleration time of hamstring (DThams) and quadriceps (DTquad), time to peak torque of hamstring (TPThams) and quadriceps (TPTquad), and functional Hamstring-to-Quadriceps ratio (PTecc/PTcon).

Conditions

Muscle Strength

Keywords

Isokinetic training; peak torque; acceleration time; deceleration time; time to peak torque; Hamstring-to-Quadriceps ratio

Outcome Measures

Primary Outcomes (1)

• Functional Hamstring-to-quadriceps ratio (PTecc:PTcon)

  This ratio was calculated using eccentric peak of hamstring and concentric peak torque of quadriceps muscle

  6 weeks

Secondary Outcomes (6)

• Acceleration time of hamstring (AThams)

  6 weeks

• Acceleration time of quadriceps

  6 weeks

• Deceleration time of hamstring (DThams)

  6 weeks

• Deceleration time of quadriceps

  6 weeks

• Time to peak torque of hamstring

  6 weeks
