Acute hormonal responses to submaximal and maximal heavy resistance and explosive exercises in men and women.

Thursday, December 01, 2005

Linnamo V, Pakarinen A, Komi PV, Kraemer WJ, Hakkinen K. Neuromuscular Research Center, Department of Biology of Physical Activity, University of Jyvaskyla, Jyvaskyla, Finland.

The purpose of this study was to examine acute hormonal and neuromuscular responses in men and women to 3 heavy resistance but clearly different exercise protocols:
  1. Submaximal heavy resistance exercise (SME)

  2. Maximal heavy resistance exercise (HRE)

  3. Maximal explosive resistance exercise (EE).

HRE included 5 sets of 10 repetition maximum (10RM) sit-ups, bench press, and bilateral leg extensions (David 210 machine) with a 2-minute recovery between the sets. In SME, the load was 70%, and in EE, the load was 40% from that used in HRE. A significant increase (p < 0.05) in serum growth hormone (GH) was observed after HRE both in men and women, but the increase was greater (p < 0.05) in men than in women. Serum testosterone (T) increased significantly (p < 0.05) only during HRE in men. Since GH and T are anabolic hormones, the acute exercise-induced response during HRE may play an important role in the long-term anabolic adaptation processes related to muscle hypertrophy and maximal strength development.
