Excellent article by Craig Pickering. Here is a snippet:
3. Testing Everything!
One rep max. Five rep max. Reaction time. 10m from blocks. 30m from blocks. Flying 30m. 60m from standing. 100m from standing. 200m from standing. 300m from standing. Peak bar velocity for power clean / snatch / squat. Peak power for power clean / snatch / squat / bench. Peak isometric power. Body weight. Skin folds. Girths. Medball throw. Standing long jump. Five bound distance. These are all the things that I can remember testing and measuring during my career. Now, there isn’t anything wrong per se with testing, so long as you put the test in its rightful place. The only real test that matters is how little time elapses between the gun going off and you crossing the finish line in an official competition. Hopefully, the time that elapses will be less than the other people in the race. Ideally, this elapsed time will be the shortest amount of time it has ever taken you to both react and cover the race distance. Your performance in every other test is largely irrelevant to this; if you improve in all your tests but get slower in a race, then monitoring those tests hasn’t been worthwhile (or at least hasn’t given the correct signal).
