Effects of isokinetic training of the knee extensors on high-intensity exercise performance and skeletal muscle buffering
Controlled trialHumans
- Design
- Controlled trial
- Subjects
- 23 trained subjects (13 at 4.19 rad/s, 10 at 1.05 rad/s) and 10 controls
- Duration
- 16 weeks, three sessions per week
- What was measured
- Isometric endurance at 60 percent MVC, mean power and work done in all-out cycling, and vastus lateralis buffer value and carnosine concentration before and after 16 weeks of isokinetic knee extensor training.
What the authors reported
The two training velocities did not differ in response. Work done during high-intensity cycling rose 9 percent in the trained group, more than in controls (P = 0.04), while isometric endurance was unchanged. Neither muscle buffer value (P = 0.56) nor carnosine concentration (P = 0.37) changed with training, so the improved performance was not attributed to increased buffering.
Limits of this study
