This article is a review of the literature on the effects of stretching on sports injuries and performance. It is critical to understand that this is a review of findings, and not a new study on the effects of stretching in regards to sports injuries and performance. The methods that were used to determine if stretching made a difference in reducing the prevalence of sports injuries and performance, was a systematic review to examine the effects of viscoelastic and neural effects of stretching. Viscoelastic effects have changes in the range of motion and resistance to stretch after an acute bout of stretching. (McHugh & Cosgrave, 2010) Neural effects when stretching are refereeing to the stretch-induced strength loss. (McHugh &

(Avela et al., 2004) It must also be noted that the loss of strength in the muscle was also shown on the opposite limb that was not stretched. (McHugh & Cosgrave, 2010) Most of the stretches that were done in the study were held for 8 minutes or less, to determine the strength loss and the power loss. Stretching technique, contraction type, and the muscle length are all factors in determining the strength loss with stretching. (McHugh & Cosgrave, 2010) Dynamic stretching showed no stretch-induced strength loss. (McHugh & Cosgrave, 2010) Different studies show that the contraction type had different results in regards to stretch-induced strength loss with eccentric contractions. The muscle length also showed no stretch-induced strength loss with longer muscles. (McHugh & Cosgrave, 2010) Based on the findings from the numerous studies within this article, stretch-induced reductions in regards to performance are fairly low with 0-8% range of change.
The summary of the findings of the effects of stretching on injury risk showed little to no effects, that stretching was beneficial in preventing injuries. Randomized trials and one longitudinal study were conducted to determine the effects of stretching on injury risk for different subject groups. The intervention for the studies involved the
