What hormone is released during strip sets of leg press?

During strip sets of leg press, the body undergoes intense resistance training that can significantly elevate the production of various hormones. Among these, Insulin-like Growth Factor 1 (IGF-1) is particularly relevant. IGF-1 is a hormone that plays a crucial role in muscle growth and repair, stimulated by factors such as resistance training and nutritional intake, especially after exercising.

When engaging in strenuous activities like strip sets, which involve performing multiple sets with progressively lighter weights until muscle fatigue is reached, the increased mechanical stress on the muscles triggers an adaptive response. This response includes the release of IGF-1, which supports muscle hypertrophy (growth) and regeneration by promoting protein synthesis and muscle cell proliferation.

In contrast, the other hormones listed have different primary roles that are not as directly tied to the response during resistance training. For example, while norepinephrine is involved in the 'fight or flight' response and helps mobilize energy during exercise, its relationship with muscle protein synthesis is not as direct as that of IGF-1. Insulin primarily regulates glucose levels and promotes fat storage, and thyroxine is mainly involved in regulating metabolism rather than muscle growth specifically associated with resistance training.

Thus, IGF-1 stands out
