Abstract

Background: In contrast with maximal voluntary resistance exercise, which is allegedly considered a potent GH stimulus in young subjects, evaluation of GH response to whole-body vibrations (WBV) has yielded conflicting results. Methods: The acute effects of WBV alone (test A), maximal voluntary isometric contractions (MVC) (test B), and combination of WBV and MVC (test C) on serum GH and blood lactate (LA) levels were studied in 9 healthy adult males. Muscle soreness was assessed 24 and 48 h after exercise by a visual analogue scale. Results: GH responses were significantly higher after tests B and C than after test A (GH peaks: 18.8±9.5 ng/ml or20.8±13.7 ng/ml, respectively, vs 4.3±3.5 ng/ml; p
