# [ReWin(d): a new sports nutrition active: clinical study & protocol](https://www.mynaturalorigins.com/en/blog/rewind-a-new-sports-nutrition-active-clinical-study-and-protocol)

In order to accompany nutraceutical industrial professionals, Natural Origins has designed a sports nutrition active for athletic performance in terms of recovery after sports. Focus on a clinical study carried out on the ReWin(d) active and the protocol set up to demonstrate its effectiveness.

 

## **ReWin(d): a new sports nutrition active used to improve athletic performance**

 

The ReWin(d) active is a naturally formulated sports nutrition product. Contrary to traditional actives, this **100% organic product uses all the benefits of plants.**

Designed by [Botanical Studio](https://www.mynaturalorigins.com/en/sourcing-botanical-ingredients-design) at Natural Origins, ReWin(d) shares the same approach as the [Exten(d) active](https://www.mynaturalorigins.com/en/blog/the-extend-active-has-demonstrated-improved-performance-and-noticeable-effects-on-decreasing-discomfort-related-to-sports-practice) and is focused on helping athletes improve their performances while caring for their health.

 

## **Clinical study on the ReWin(d) active: protocol & test procedure**

 

### 1. Clinical study protocol

 

**ReWin(d) is an active made from low processed plants.** As such, it contains the plant totum with the scientifically proven benefits supported by a clinical study.

An independent laboratory was assigned to carry out of the clinical trials on the ReWin(d) active. The parameters of this **double blind clinical trial carried out over a 4-week period** include that:

- The trial was carried out on 40 volunteer athletes,
- aged between 20 to 25 years old,
- spread out in one « ReWin(d) » group and one placebo.

 

### 2. Clinical study on the ReWin(d) active procedure

 

In order to analyse the effects of ReWin(d) on muscular damage caused by intense sports practice, the volunteers underwent 2 types of exercise to simulate intensive physical exercise in a laboratory:

 

- Exercise 1 : plyometric drills : this exercise involved 10 cycles of 10 repeating jumps with weights with a 1 minute break between sets.

- Exercise 2 : eccentric quadricep movements : this involved going from one to another for a total of 3 cycles combining a series of exercises.

 

Both of these exercises were high-intensity to « simulate a semi-marathon » or trail type activity.

The objective was to provoke muscle inflammation causing pain within 72 following the physical effort. (Delayed-Onset Muscular Soreness, DOMS) [1] or muscle soreness.  

These exercises allowed monitoring inflammation and pain before physical effort along with monitoring during the 72 hours post physical effort following a 4-week ReWin(d) cure period.
