Specificity & Transfer of training effect paradox
The “training effect paradox” usually refers to the idea that the very act of training — meant to make you fitter, stronger, or better — can simultaneously make you more fragile or vulnerable in certain ways. It captures the tension between adaptation and risk.
It’s easy for coaches and athletes to fall into the trap of choosing only exercises or training regimes that are as sport specific as possible. If one needs to do Handstand walks he should practice them as much as possible. If one needs to sprint fast he should practice sprints, etc. The logical idea behind this choice is that training that mimics the sport as much as possible will result in the greatest transfer to the sport itself.
However, ones that adopt blindly this model fail to understand that athletes need to an element of overload that build them physically and psychologically and this is acquired by specific and non specific training methods.
Training provides a stress stimulus (mechanical, metabolic, or neural).
The body responds through fatigue → recovery → adaptation (supercompensation).
If the stress is repeated too soon (before full recovery), performance capacity decreases. But if the stress is too infrequent, adaptations regress.
Let’s use a sprinter athlete as an example:
It seems obvious that for one to improve sprint performance, one should have sprint training in his prescription. But sprints and being anaerobic developed is directly related to strength development. So if one is not strong enough he could spend a lot of time in “sprint training “ without showing significant results for the amount of training done. In this situation a coach that invests in a prescription that seems less “sport specific “ but develops that athlete to be physically and psychologically ready to sprint may get better results in the mid and long term.
The training effect paradox is that the pursuit of peak performance requires walking a fine line — where the same stress that drives adaptation also increases vulnerability. Too little, no adaptation; too much, breakdown.
So remember that a training prescription that is all about being as sport specific as possible, may get you to sweat a lot, move a lot or spend a lot of time in the gym, but does not guarantee results.
The coach’s art is in knowing when to apply specificity and when to emphasize transfer-building work.
