Lactic acid build-up was the cause of muscle fatigue.
The answer to this question would be DNA
DNA or d<span>eoxyribonucleic acid is the molecule that used to record the human genetic information. By studying the DNA sequence and how to cut the DNA, the scientist able to observe the genome pattern. Later, this was used to record the human genome.</span>
None of these! I assume the answer your instructor is looking for is maxing out. It’s the most effective option, but also the one with most risk.
However, the best way and frankly the gold standard way to asses muscular strength is via a maximal voluntary isometric contraction using a dynamometer. No weights need to be selected here, it’s your muscle isometrically contracting at a specific joint angle for 3-5 seconds. Usually 3 attempts are required. The highest force output in Newton’s is recorded as max strength.
Could you give us the answer choices? It says 'which'... That should mean there are multiple answer choices.
