My thoughts :
I think what happens often is the information in team sports does not " need" to be great. I think training methodology in team sports often gets watered down so much so that not only are you not playing to individuals strengths and working on their weaknesses, coaches are missing how to model training because they have not known anything different.
I am at a loss to understand the role of distance running in soccer to get fit? The coaches read the first sentence of an internet blog that the average ( pro player not 12 or 13 year old boys not yet past puberty) soccer player runs 13 k or something like that. ( depending on your position) . It’s the analysis and how they interpret what running all this distance means that is seriously mistaken. ( well , if you want to develop speed and power to ones potential and not just coast on what each person has in their back pocket)
In a team setting it’s easy that the blame for not winning might be due to a variety of reasons. The coach, the system, the athlete , poor competition…The actual training methodology really never goes under too much scrutiny as it does when you have one coach and one athlete in individual sports. In the highest level of professional team sports you get pissing matches between owners ( who are business people first) , doctors ( who know the human body ( sort of) but nothing about training , the therapist ( who are so low on the totem pole no body cares what they think) and sometimes nothing ’ great’ can happen because you get all sorts of people not agreeing on anything. The end result? Well the opposite are coaches who go it alone and fund everything them selves.
I think if more people might understand the idea of speed reserve we would make some serious progress in team sports and speed and power coaching in general. That forces the question on how to achieve SR , then the question about speed development and the best ,most effective way to train for it and apply that info to the desired sport.
