Journal Article 2019 06 16   <br /><strong> Aim:</strong> To achieve further progress, particularly in professional sport training new protocol to evaluate the effect of warm-up stretching exercises on fitness factors is essential. This study aimed to compare the static-dynamic stretch protocols at the same time warm up before exercise high intensity intermittent aerobic and fitness training young football players were periodic Football factors. <strong>Methods:</strong> 24 young football players (3±18 years of age,4±176 cm tall and 4±68kg)were selected and randomly divided into two groups of 12.Training for 6weeks, six days a week (three days training and one day of rest)and each session was 60 minutes. One group consisted of static and dynamic synchronous stretching warm-up 8 seconds followed by 4-minute running at 95% of the maximum pulse intensity and the second group consisted of 15-minute static and dynamic synchronous stretching exercise. It was 4 minutes 4 minutes of playing soccer on a small field. Before and after the course, the flexibility, speed, explosive power, agility, subcutaneous fat percentages were measured. <strong>Results:</strong> The results showed that the two models of warm-up training significantly increased flexibility, anaerobic power, speed and agility, and a significant decrease in the percentage of subcutaneous fat (p≤0.05). However, the record anaerobic power and flexibility, the second group compared with the first group increased to a greater extent (05/0 p≤). <strong>Conclusions:</strong> In general, high intensity aerobic exercise and play in small lands after warm-up protocol The elongation of the selected temporal lobes increased the biomotor characteristics of the subjects, especially after a 15-second stretch, and played an important role in improving the flexibility, agility, power, and speed of the subjects.   <br /><strong> Aim:</strong> To achieve further progress, particularly in professional sport training new protocol to evaluate the effect of warm-up stretching exercises on fitness factors is essential.
