Abstract

We investigated the effectiveness of stretch reflex programs (SRPs) in 17 male students (mean age: 20.2 ± 0.9 years) who were track and field athletes. The effect of the SRP conditions in improving the 100-m sprint performance was explored. The different training environments were level ground, uphill, and downhill, and the subjects were assigned evenly to an SRP group for each environment and a control group. The students performed their SRPs (rebound jump, slalom jump, single-leg hop (right and left), bounding, and speed bounding) three times a week for 9 weeks. The control group received regular training. The primary findings were as follows:

1. Over 0 to 30 m, the SPR groups showed improved pitch and stride under all conditions, with a marked improvement in the downhill training environment group.

2. An SRP using a downhill slope of four degrees or less was effective as a training environment to improve sprinting speed in the acceleration period.

3. An SRP using an uphill slope was a suitable environment for improving only the pitch in sprinting.

4. The improvement in stride between 0 and 30 m in the downhill SRP group likely contributed to increases in both pitch and stride between 30 and 100 m.

These results showed that an SRP performed downhill increased pitch and its tradeoff counterpart—stride—effectively between 0 and 30 m and significantly improved sprinting speed over 30 to 100 m. The study therefore demonstrated that downhill is the most appropriate environment for SRP training.
