The purpose of this study was to determine whether resistance training through a full range of motion could be as effective or more effective than static stretching of the same joints. Twenty five volunteers were randomly placed in two groups: resistance training (RT) and static stretching (SS). The subjects hamstring extension, hip flexion, shoulder extension flexibility, and peal torque of quadriceps and hamstrings were pretested prior to completing a 5 week static stretching or resistance training intervention.
The results concluded that there was no difference between the two groups suggesting that resistance training through a full range of motion is potentially as effective as static stretching.
This study speaks to how important strength training through a full range of motion is. Often athletes perform weight training with half or three quarters full range of motion. However, as this small study begins to point out, if we can get our athletes to perform full range of motion on all strength training exercises, we can get them more flexible while improving their strength. Larger studies with longer durations will need to be studied to support or disprove these results.
