Nylig publisert studie:

69 forsøkspersoner ble delt inn i tre grupper:

Gruppe 1: fikk wheyprotein før trening
Gruppe 2: fikk wheyprotein og kreatin før trening
Gruppe 3: fikk wheyprotein, kreatin og 6g CLA før trening.

I løpet av fem ukers trening, hadde gruppe 3 økt styrken sin i benkpress og benpress mer enn gruppe 1 og 2 tilsammen!
Å innta CLA før trening hadde med andre ord en veldig god effekt på styrken.

Conjugated linoleic acid combined with creatine monohydrate and whey protein supplementation during strength training. [Journal Article, Randomized Controlled Trial, Research Support, Non-U.S. Gov't]
Int J Sport Nutr Exerc Metab 2009 Feb; 19(1):79-96.

"PURPOSE: The authors examined the combined effects of conjugated linoleic acid (CLA), creatine (C), and whey protein (P) supplementation during strength training.
METHODS: Sixty-nine participants (52 men, 17 women; M +/- SD age 22.5 +/-2.5 yr) were randomly assigned (double-blind) to 1 of 3 groups: CCP (6 g/d CLA + 9 g/d C + 36 g/d P; n = 22), CP (C + P + placebo oil; n = 25), or P (P + placebo oil; n = 22) during 5 wk of strength training (4-5 sets, 6-12 repetitions, 6 d/wk). Measurements were taken for body composition (air-displacement plethysmography), muscle thickness (ultrasound) of the flexors and extensors of the elbow and knee, 1-repetition-maximum (1-RM) strength (leg press and bench press), urinary markers of bone resorption (N-telopeptides, NTx), myofibrillar protein catabolism (3-methylhistidine; 3-MH), oxidative stress (8-isoprostanes), and kidney function (microalbumin) before and after training.
RESULTS: Contrast analyses indicated that the CCP group had a greater increase in bench-press (16.2% +/- 11.3% vs. 9.7% +/- 17.0%; p < .05) and leg-press (13.1% +/- 9.9% vs. 7.7% +/-14.2%; p < .05) strength and lean-tissue mass (2.4% +/- 2.8% vs. 1.3% +/-4.1%; p < .05) than the other groups combined. All groups increased muscle thickness over time (p < .05). The relative change in 3-MH (CCP -4.7% +/- 70.2%, CP -0.4% +/- 81.4%, P 20.3% +/- 75.2%) was less in the groups receiving creatine (p < .05), with the difference for NTx also close to significance (p = .055; CCP -3.4% +/- 66.6%, CP -3.9% +/- 64.9%, P 26.0% +/- 63.8%). There were no changes in oxidative stress or kidney function.
CONCLUSION: Combining C, CLA, and P was beneficial for increasing strength and lean-tissue mass during heavy resistance training."
