Twelve weeks supplementation with an extended-release caffeine and ATP-enhancing supplement may improve body composition without affecting hematology in resistance-trained men.

What Was Tested

This randomized controlled trial looks at Caffeine.

Therefore, the purpose of this investigation was to determine the effects of this supplement on body composition when used in conjunction with 12 weeks of resistance training.

Why It Was Studied

A novel supplement containing ancient peat and apple extracts has reported enhanced mitochondrial ATP production and it has been coupled with an extended-release caffeine.

Who Took Part

PubMed indexes the participants as adults, men only.

Twenty-one resistance-trained subjects (27.2 ± 5.6y; 173.5 ± 5.7 cm; 82.8 ± 12.0 kg) completed this study.

How the Study Was Run

The researchers set it up as a randomized and placebo-controlled study.

Because people in this Caffeine study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The comparison arm used a placebo, so changes seen with Caffeine could be set against what happens without it.

Body composition was assessed using DEXA and ultrasound at weeks 0, 4, 8, 10, and 12.

Vital signs and blood markers were assessed at weeks 0, 8, and 12.

What Was Measured

The subject headings attached to it are Adenosine Triphosphate, Biomarkers, Blood Cell Count, Body Composition, Caffeine, Creatinine and Dietary Supplements.

The authors tagged it with the keywords Elevatp, Ergogenic aid, Hypertrophy, Purenergy and Safety.
