We use all of those:
The first test all athletes are to perform is taking pulse rate immediately upon. If the resting pulse is 10 beats or more then normal, the athlete is to deload for that training session. The same goes for a tempo day. If the athlete is above beats more then normal a low volume of tempo run is to be performed.
The second test is the measurement of slj or vj 3-6 reps to test the neuro muscular system. This test is performed on all cns intensive days after the warmup is completed. A standard will be set, and the athletes must try to reach that standard. If the athlete is higher to 2-5% below the standard he or she is to train all out. If the athlete is more then 2-5% below the standard he or she is to deload for that session.
I posted all this infor before.
