According to research, chronic, long-term stretching protocols tend to lead to which of the following?

Increased injury rates or increased injury risk

Explanation:

Chronic, long-term stretching protocols are often used by athletes for improved physical performance and muscular flexibility. However, it has been found through research that continuous implementation of long-term stretching protocols can lead to higher risk of injury specially muscular injuries. This can be a result of muscular fatigue. The muscles need some resting time before another stretch and overstretching can be a risk factor specially when the muscles are fatigued.
