• Registration Number: NCT02923102
• Lead Sponsor: Vital Solutions GmbH

Brief Summary

The aim of the study is to investigate a pre and post workout supplementation (15 days) with Recoverben® , a Aloysia citriodora extract on recovery after exhaustive exercise. Effects will be investigated with 400mg Recoverben® and compared to placebo.

Detailed Description

The aim of the study is to investigate a pre and post workout supplementation (15 days) with Recoverben® , a Aloysia citriodora extract on recovery after exhaustive exercise. Effects will be investigated with 400mg Recoverben® and compared to placebo.

Targeted parameter will be determined at the beginning of the study and after supplementation, each. Parameter include maximal strength (MVC), muscle soreness (VAS), pain sensitivity (Algometry) and biomarkers (CK, IL-6, glutathione peroxidase).

Arm && Interventions

Group	Intervention	Description
Aloysia citriodora extract	Aloysia citriodora extract	Dietary Supplement: Aloysia citriodora extract
Placebo Formulation	Maltodextrin	Dietary Supplement: Maltodextrin (no active ingredient)

Primary Outcome Measures

Name	Time	Method
Change of muscle soreness (VAS) over time	Chance over time after 10 days of supplementation (pre stress test and 3h, 24h, 48 h, 96h after stress test)	In the current study, pain following eccentric exercise will be assessed by using a 100 mm visual analogue scale after the subjects performing a standardized movement.

Secondary Outcome Measures

Name	Time	Method
Change of pressure pain (Algometry) over time	Chance over time after 10 days of supplementation (pre stress test and 3h, 24h and 48 h after stress test)	The threshold for pressure induced pain will be measured using an algometer.
Change of creatine kinase over time	Chance over time after 10 days of supplementation (pre stress test and 3h, 24h and 48 h after stress test)
Change of of glutathione peroxidase over time	Chance over time after 10 days of supplementation (pre stress test and 24h and 48 h after stress test)
Change of interleukin-6 over time	Chance over time after 10 days of supplementation (pre stress test and 3h, 24h and 48 h after stress test)
Monitoring of related adverse events	During study execution over 15 days	Reporting of adverse effects to evaluate tolerability
Change of retrospective pain (Likert scale) over time	Chance over time after 10 days of supplementation (pre stress test and 24h, 48h, 96h after stress test)	Evaluation of the perceived pain retrospectively by using the Likert scale for muscle soreness
Change of maximal concentric strength/ maximal voluntary contraction (MVC) over time	Chance over time after 10 days of supplementation (pre stress test and 3h, 24h and 48 h after stress test)	Maximal concentric strength of the M. Quadriceps femoris will be assessed by measuring maximal isometric concentric strength using a dynamometer
