Reply To: sprint training for sport
If I can also contribute, there are two things that need to be taken into consideration:
1- what is the purpose of the sprint training? Is it for conditioning, or is it for improving speed? If it is for conditioning, then the demands of energy system should be considered and appropriately applied as per the needs of the athlete, as per what Ryan mentioned. If it is to improve speed, then it is important to identify what elements of biomechanics the athlete needs to improve vs being structurally stronger (usually a combination of these).
2- what part of the season is the athlete in? if it is "in-season" it is important to consider what the sport coach is making the athlete do. In my experience, many sport coaches burn out their players by making them volumes of full sprints during their specific training session. When this is the case, making the athlete do more sprint training may cause more damage than good. If, on the other hand, it is in the off season, you could emphasize a higher ratio of speed to strength training session within various mesocycles ie 3:3 for 4 weeks, followed by 2:4 for the next 4 weeks, and of course within each mesocycle, the priorities are addressed...With all this in mind, it is important to consider Ryan's advice with respect to the CNS.
