Table 4.
Coaches’ responses to sled loading prescription methods and magnitudes for resisted sprint training programming.
| Absolute (n) | Relative (%) | |
|---|---|---|
| Loading prescription methods | ||
| % Velocity decrement | 9 | 47.4 |
| % Body mass | 7 | 36.8 |
| Did not determine | 2 | 10.5 |
| Other | 4 | 21.1 |
| Magnitude of sled loads | ||
| Light (2.5% to 10% Vdec or 2.5% to 20% BM) | 9 | 47.4 |
| Moderate (10% to 30% Vdec or 20% to 50% BM) | 9 | 47.4 |
| Heavy (>30 Vdec or >50% BM) | 0 | 0 |
| Other | 1 | 5.2 |
Vdec: velocity decrement; BM: body mass. “Other” responses included factors such as “perception of effort” and “video analysis of the movement” for sled loading prescription methods, and “it depends on the period of the season” for sled loading magnitude.
