While certain plants are recognised for their analgesic or stimulating effect , it is difficult to scientifically demonstrate the effects .
To prove the effectiveness of the new sports nutrition ReWin(d) active, Natural Origins conducted a clinical trial.
Results show that ReWin(d) not only reduces soreness but also improves sports performances by considerably reducing the recuperation time following an intense physical effort.
Focus on results highlighted by the clinical trial.
1. Measure muscular inflammation and DOMS* (delayed onset muscle soreness) with and without the ReWin(d) active
Two groups of volunteers did the same exercises: one including a combination of pylometric movements and CMJ (countermovement jump), and the other eccentric movements. The objective was to simulate intense physical exercise leading to the onset of DOMS*, which appear between 24 to 72 hours following intensive muscular exercise .
The results of the clinical study show that delayed onset muscle soreness (DOMS) disappear more quickly with subjects having been administered ReWin(d). In effect, while leg muscles for the placebo group keep the same inflammation level after 24, 48 and 72 hours, a substantial decrease in inflammation is noted after 48 hours in the case of the ReWin(d) subjects. Moreover, inflammation continues to decrease at the end of 72 hours, proving that ReWin(d) enables considerably reducing recuperation time following intense physical exercise.
2. Pain reduction thanks to the ReWin(d) active
Inflammation is necessarily accompanied by pain. The doctors in charge of this clinical study thus studied the perception of pain using 2 tests: an evaluation of dynamic pain and static pain.
An increase in dynamic pain was observed with the placebo and logically was stable in the case of ReWin(d). Static pain was still present at the end of 72 hours with the placebo whereas it had disappeared at the end of 48 hours with ReWin(d).[AM1]
ReWin(d) thus has an analgesic effect.
3. Improved sports performance and cardiac variability
Performances were evaluated by using a test to measure the height of jumps. Athletes using placebos returned to their original level of performance after 72 hours. On the contrary, an increase in performance was noted with those athletes using ReWin(d) after 24, 48 and 72 hours. The effect observed with regard to inflammation logically improves performance.
Heart rate variability was measured and likewise confirmed this increase in performance. This parameter is a recognised marker for well-trained athletes.
The heart rate variability for athletes using ReWin(d) was higher after 24 hours compared to athletes using placebos. This difference was still noticeable after 48 hours.
This demonstrates that the return to the original level is faster with ReWin(d) and thus enables decreasing recuperation time between 2 physical efforts.
ReWin(d) has a significant effect on muscular inflammation and on local pain.
Athletes using ReWin(d) tend to recuperate better as heart rate variability (HRV) returns to its original level within 72 hours.
Finally, as ReWin(d) eases DOMS, it enables athletes to do one training set after another thanks to a reduced recuperation time and thus improve their performances.
