Resistance Training on Growth Factors

Acute Effect of Resistance Training With Different Intensity on Circulating Levels of Neurotrophic Growth Factors and Homocysteine in Young Adults

The goal of this clinial trial study is to explore the effect of high or low intensity resistance training (LIRT) under similar training volume on change in serum levels of BDNF, IGF-1, VEGF, irisin, and plasma Hcy in young adults.The main questions it aims to answer are:

1. Whether high and low intensity will increase the serum levels of BDNF, IGF-1, VEGF, irisin, and reduce plasma Hcy.
2. whether a greater magnitude of change would be suffer in low intensity group when compared to high intensity group, as an effect of greater physiological adaptation produced by more repetitions required to complete.

Participants will performe two different intensity resistance training (HIRT, at 80%1RM with 12 repetitions and 4-5 sets and LIRT, at 40%1RM with 24 repetitions and 4-5 sets).

Researchers will compare the training effects of two different training on these growth factors.
