Model summary for multiple regression for hamstring strain rate
| Model variables included | R | R2 | SE Est |
|---|---|---|---|
| The model components include: 1, One predictor: (constant), hamstring stretching holding time (SHT) (seconds); 2, two predictors: (constant), SHT (seconds) and use of standard stretching protocol (SSP); 3, three predictors: (constant), SHT (seconds), SSP, and stretching technique employed STE. (1) SHT indicates the extent to which the stretching holding time used influences the tendency for injury prevention; (2) SSP indicates the extent to which the use of standard stretching protocols used influences the tendency for injury prevention; (3) STE indicates which stretching techniques employed influence the tendency for injury prevention. | |||
