The Effect Of Interval Training (short-short, Short) On Rsa Speed Repetition Efficiency In Under 19-year-old Football Players.

Résumé

This study examines how different interval training intensities impact young football players' repetitive sprinting ability. The study focuses on comparing two interval training intensities: "very short" and "short". For this purpose, an experimental design was employed. Eighteen players (age: 18 ± 0.5 years, height: 175 ± 4 cm, weight: 70 ± 3 kg) were purposefully selected and equally divided into two groups. Each group underwent a specific interval training protocol for a duration of 12 weeks. Group 1 performed a 'very short' program (10s high-intensity ;120% MAS, 10s rest), while Group 2 performed a 'short' program (20s high-intensity ;105% MAS, 20s rest). The RSA test was used to measure the fatigue index. After collecting and statistically analyzing the data using t-test, the findings showed the effectiveness of very short interval training in improving the repetitive sprint ability in football players under 19 years old.
