The main purpose of this critical review was to analyze the acute effect of stretching exercises as part of the warm-up on various strength and power measurement tests (isometric test, isokinetic test, jump test, and agility and coordination test) used to evaluate the acute effect of the stretch. The use of stretching as an important part of all warm-ups has been widely recommended. However, the number of scientific studies that question the inclusion of stretching exercises in the warm-up has grown in recent years. A critical analysis of the scientific literature could be very helpful to assess whether pre-stretching may affect the subsequent sport performance. This knowledge is essential for athletes, especially those who play sports that involve strength and power skills throughout the course of training and competition. The analysis of the scientific literature has shown that dynamic stretching has a positive effect on the different evaluation tests (isokinetic, jump performance, and functional tests), while static stretch routines have a negative effect, showing a significant decrease in isometric test performance (with stretching doses greater than 60-90s per muscle group), isokinetic test performance (affecting maximal voluntary concentric contraction mainly), jump performance (for the SJ and CMJ) and functional test that evaluate sprint performance.
