Effect of resistance exercise and growth hormone on bone density in older men.

What Was Tested

Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this randomized controlled trial publication.

Who Took Part

By PubMed's age tags, the people studied were older adults, men only.

Serum osteocalcin and IGF-I were determined by radioimmunoassay before, during and at the end of treatment.

How the Study Was Run

The design is described as randomized, double-blind and placebo-controlled.

Because people in this Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the participants nor the staff measuring them knew who was on Exogenous HGH, sermorelin & older GHRPs (why they're passed over), so expectations could not easily colour the readings.

Some participants received a placebo instead of Exogenous HGH, sermorelin & older GHRPs (why they're passed over), giving a reference point.

Before and at the end of 16 weeks of resistance exercise with or without GH administration, body composition, whole body and regional bone mineral density (BMD) were determined by dual-energy X-ray absorptiometry.

What Was Measured

Topics PubMed links to this paper include Biomarkers, Bone Density, Exercise, Growth Hormone, Insulin-Like Growth Factor I and Osteocalcin.

The publication is from 1997 (Clinical endocrinology), a journal based in England.
