The Effect of Curcumin Supplementation on Recovery From Exercise-induced Muscle Damage

Study Overview
=================
Brief Summary
-----------------
Recent evidence suggests that curcumin supplementation may reduce muscle inflammation, oxidative markers, and muscle damage. The most favourable dosage to elicit these ergogenic effects are yet to be established; both 750mg & 1500mg has been shown to be effective. Curcumin supplementation has been ingested in numerous different ways however, no previous research to date has used curcumin in a hydrolysed (drinkable) format. The aim of this study is to investigate whether hydrolysed curcumin can reduce indices of muscle damage and improve recovery, whilst also examining a potential dose-response effect.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Curcumin Single<br>The Single dose group will consume 1 placebo sachet and one curcumin sachet per day. Curcumin supplementation will be from YourZooki, the supplement in question is commercially offered to the public in a tangerine flavour. The sachets will be in 750mg hydrolysed format. The placebo is a sachet containing the same ingredients mentioned above minus the curcumin. The sachets will be in 750mg hydrolysed format. Supplementation will be administered and commence 48-hours prior to the first testing day and will be consumed twice a day (8am & 8pm). | Dietary Supplement: Curcumin<br>* Curcumin Supplementation<br>|
| Experimental: Curcumin Double<br>The double dose group will consume two sachets per day of curcumin. Curcumin supplementation will be from YourZooki, the supplement in question is commercially offered to the public in a tangerine flavour. The sachets will be in 750mg hydrolysed format. Supplementation will be administered and commence 48-hours prior to the first testing day and will be consumed twice a day (8am & 8pm). | Dietary Supplement: Curcumin<br>* Curcumin Supplementation<br>|
| No Intervention: Placebo<br>Placebo sachets containing the same ingredients mentioned above minus the curcumin. The sachets will be in 750mg hydrolysed format. Participants will consume two sachets per day. Supplementation will be administered and commence 48-hours prior to the first testing day and will be consumed twice a day (8am & 8pm). | |
