The purpose of this study was to examine the effects of CLA supplementation in conjunction with 6 weeks of aerobic exercise training on the physical working capacity at the fatigue threshold (PWCFT), timed sit-ups, and the standing long jump. Thirty-three untrained to moderately trained men (mean ± SD; age = 21.6 ± 2.8 years) participated in this double-blind, placebo controlled study and were randomly assigned to either a CLA (Clarinol A-80; n=17) or placebo (PLA; sunflower oil; n=16) group. Before and after 6 weeks of aerobic training (50% V[Combining Dot Above] O2 peak for 30 min, twice per week) and supplementation (8 mL CLA or PLA per day), each subject completed an incremental cycle ergometer test to exhaustion to determine the PWCFT, maximal number of sit-ups in 1 minute, and the standing long jump. There were no differences (all p≥0.23) between the CLA and PLA groups for the ANCOVA adjusted post-test means for PWCFT, sit-ups, or standing long jump. The PWCFT increased from pre- to post-training in the CLA (p=0.003) and PLA (p=0.003) groups. There were no differences (p>0.05) from pre- to post-training for sit-ups and standing long jump in either the CLA or PLA groups. There was no effect of CLA on the training-induced increases in PWCFT, nor were there any effects of CLA or aerobic training on the maximum number of sit-ups or standing long jump. Thus, CLA had no ergogenic benefits on this model of aerobic training-induced improvements in neuromuscular fatigue, or on field tests of muscle endurance and power.
