Fitness testing and training zones

One test per component of fitness
Each fitness test targets ONE named component, under a fixed protocol. The MULTI-STAGE FITNESS TEST (the "bleep test") measures cardiovascular endurance. SIT-AND-REACH measures flexibility at the hip and lower back. The 30-METRE SPRINT measures speed. The STANDING VERTICAL JUMP measures power. A GRIP DYNAMOMETER or one-rep max measures strength. The ILLINOIS AGILITY TEST measures agility. Naming the test AND the component it measures is worth more than naming either alone.
Valid, or just repeatable
A test is VALID if it actually measures the component it claims to. A test is RELIABLE if it gives the same result when repeated under the same conditions. The two are not the same: a test can be perfectly reliable and still invalid — a grip dynamometer reliably measures grip strength, but it would be an INVALID measure of cardiovascular endurance, however consistently it were used for that purpose.
Why the protocol must not change
A pre-training and post-training comparison is only fair if everything except fitness stayed the same: the same test, the same surface, the same warm-up, ideally the same time of day. Testing on grass and then on a track, or tired and then rested, changes the SCORE without any real change in fitness — and a coach reading that as progress or decline would be wrong for a reason that has nothing to do with training.
Calculating a training zone
Maximum heart rate is commonly estimated as 220 MINUS AGE. A moderate aerobic training zone is roughly 60 to 80 percent of that maximum. For a 16-year-old: maximum = 220 minus 16 = 204. Sixty percent of 204 is about 122 beats per minute; eighty percent is about 163. Training between roughly 122 and 163 beats per minute keeps this athlete's effort inside the intended zone — too low and the stimulus is too small to adapt to, too high and it shifts toward anaerobic effort instead.
Rating effort without a heart-rate monitor
RATE OF PERCEIVED EXERTION (RPE) asks a performer to rate how hard an effort feels, commonly on a scale from 6 to 20 or a simplified 1 to 10. It needs no equipment, correlates reasonably well with actual heart rate, and lets a coach monitor a whole squad at once. It is SUBJECTIVE, so two people working equally hard can report different numbers — useful as a guide, not a replacement for measured heart rate when precision matters.
Testing, then training, one athlete
A 17-year-old's bleep test score places her cardiovascular endurance in an average band for her sport. Her coach sets a training zone: maximum heart rate 220 minus 17 = 203, so a 60 to 80 percent zone of roughly 122 to 162 beats per minute. She trains in that zone for six weeks, using the SAME bleep test protocol, same surface, same time of day, to retest. A higher score now is real evidence of adaptation, because the only thing that was allowed to change between the two tests was her fitness.
