This blog is a summary of an article by UK sports science student Jamy Clamp and looks at how to develop efficient athletes in track and field which has implications for all athletes of all disciplines and levels.
This has some real gems local/amateur coaches and players should look at far more closely then we currently (if at all) so here's the best bits I picked up from it:
- Fatigue is not the point of muscle exhaustion but rather it's where force production decreases inhibiting (stopping) quality muscle contractions.
- Force production and application are different and if the quality of those fluctuate individually or at the same time, then inefficiency will exist
- Inefficiency is metabolically draining and it predisposes players to injury
- Poor proprioception correlates with high fatigue (decreased coordination or inefficiency)
- Inefficiency places extra stress on joints
- Extra joint stress results in greater joint instability
- Joint instability is another energy leak/inefficiency
- When under fatigue the muscular system requires more impulses than the central nervous system can supply so then neuromuscular efficiency declines and so does force production
- Anti-rotation, or the ability to resist rotational forces through the core, is the maybe the biggest energy leak, especially through the middle of the body
