Figure 2. Stretching procedures. (a) Static stretching: Each participant assumed a standing upright position and placed their right heel (with an extended leg) on a 50-cm-high platform. The participant then reached forward with their arms toward the extended leg while maintaining a proper lordotic curve. (b) Dynamic stretching: Each participant assumed a standing upright position, then intentionally contracted the right hip flexors with the knee extended and flexed their right hip joint so that their right leg swung up to the anterior aspect of their body.
