NCT02765945

Brief Summary

This is the second phase of a study designed to determine the immunological effects of long-term exercise on risk factors for ischemic heart disease (phase 1) and osteoporosis (phase 2). The results indicate that six months of moderate intensity exercise reduces bone resorption and increases the secretion of anti-osteoclastogenic cytokines by peripheral blood mononuclear cells.

Outcome Measures

Primary Outcomes (6)

  • Evidence of altered bone resorption and/or production as measured by measurements of serum levels of osteocalcin and degradation products of Type I collagen (C-terminal telopeptides)

    6 months

  • Evidence of altered secretion of osteoclastogenic cytokines by peripheral blood mononuclear cells

    secretion of IL-1 alpha, TNF-alpha, IFN-gamma by cultured peripheral blood mononuclear cells

    6 months

  • Evidence of altered secretion of anti-osteoclastogenic cytokines by cultured peripheral blood mononuclear cells

    secretion of IL-10, IL-4, TGF-beta, IL-6 by cultured peripheral blood mononuclear cells

    6 months

  • Evidence of altered blood mononuclear cell phenotypes

    Immunophenotyping of blood mononuclear cells by FACScan flow cytometer

    6 months

  • Evidence of altered serum factors of bone homeostasis

    Measurements of serum levels of estradiol, testosterone, PTH, IGF-1

    6 months

  • Evidence of altered secretion of growth and differentiation factors by cultures peripheral blood mononuclear cells

    Measurements of IL-2, IL-4, IL-12

    6 months

Interventions

Subjects were enrolled in a hospital-based wellness center where, after analysis of their medical history and previous levels of physical activity ands documentation of a normal exercise stress test, they chose individually tailored exercise programs
