Older Adult Training Study With Creatine and CLA (OTR)

May 15, 2007 updated by: Hamilton Health Sciences Corporation

Creatine Monohydrate and Conjugated Linoleic Acid Improve Strength and Body Composition Following Resistance Exercise in Older Adults

We examined whether creatine monohydrate (CrM) and conjugated linoleic acid (CLA) could enhance strength gains and improve body composition (i.e., increase fat-free mass (FFM); decrease body fat) following resistance exercise training in older adults (> 65 y). Our study hypothesized that administering CrM and CLA would yield greater strength and body composition benefits than the placebo group over the six months of resistance exercise

Detailed Description

Men (N=19) and women (N=20) completed six months of resistance exercise training with Creatine Monohydrate (5g/d) + Conjugated Linoleic Acid (6g/d) or placebo with randomized, double-blind, allocation.Outcomes included; strength and muscular endurance, functional tasks, body composition (DEXA scan), blood tests (lipids, liver function, CK, glucose, systemic inflammation markers (IL-6, C-reactive protein)), urinary markers of compliance (creatine/creatinine), oxidative stress (8-OH-2dG, 8-isoP) and bone resorption (Ν-telopeptides).
