Final answer:
For the Delorme method, if the third set's weight load is 180 lbs, the second set's weight should be 75% of this, which is 135 lbs. However, this value doesn't match any of the provided options, suggesting an error in the question.
Step-by-step explanation:
When applying the Delorme method, the patient's weight load for the third set is at 100% of the calculated value. With this method, the weights for the sets increase incrementally; the first set is at 50%, the second set at 75%, and the third set at 100% of the patient's one-repetition max (1RM). Therefore, if the third set's weight load is 180 lbs, which represents 100%, the weight load for the second set would be at 75% of this figure.
To calculate the weight load for the second set, we take 75% of the third set's weight, which is 180 lbs. So we multiply 180 lbs by 0.75 (75%) to find the second set's weight:
180 lbs × 0.75 = 135 lbs
However, none of the options given match this calculation, which indicates a potential error in the options provided. If the question may have a typo or mistake, please double-check the values given, as it's important for the calculation of weight loads in any resistance training program like the Delorme method.
