Summary

This study aimed to investigate the effect of different doses of hydrolyzed collagen (HC) with resistance exercise (RE) on whole body collagen synthesis in healthy young and older males and females.

Interventions

DIETARY_SUPPLEMENT

Experimental: Consumption of three different doses of hydrolyzed collagen (HC) with reistance exercise

Each trial lasts for seven hours and while participants consumed HC, performed resistance exercise and rested, 10 x 5 mL blood samples were collected from a superficial forearm vein using a cannula. All trials were performed at the same time of day (08:00 - 15:00). Different doses of HC (0 grams, 15 grams and 30 grams) and 50 milligrams vitamin C were dissolved with 250 milliliter water in an opaque bottle. To match calories of 30 grams HC, 34.1 grams and 15.4 grams maltodextrin was used in 0 grams HC and 15 grams HC respectively. Also to mask any potential difference in HC doses, 4 grams non-caloric sweetener was used in all HC doses. The details of nutritoinal supplements used are as follows: Hydrolysed collagen (Myprotein, Cheshire, UK), Vitamin C powder (Holland and Barrett Retail Limited, Warwickshire, UK), Maltodextrin (Myprotein, Cheshire, UK), and Non-caloric sweetener (Truvia®, SilverSpoon, London, UK)
