Brief summary

Positive effects of herbal supplements such as red berries, ginseng, ashwagandha on athletic performance have been reported. The aim of this study was to evaluate the acute effects of a herbal dietary supplement prepared from a mixture of red berries, ginseng and ashwagandha on aerobic performance of recreational athletes.

Detailed description

In the beginning of the study anthropometric measurements (weight (kg), height (cm), BMI, waist circumference (cm), body fat percentage, lean body mass, skeletal muscle mass) will be taken from the participants who accepted to participate in the study. During the study, participants will be restricted from consuming alcohol, caffeine, red fruit, ginseng and ashwagandha. First, Yoyo Intermittent Recovery Level 1 performance test (The Yo-Yo test is a maximal aerobic endurance fitness test, involving running between markers placed 20 meters apart, at increasing speeds, until exhaustion) will be done to all participants In this step, participants will not drink anything. Then there will be a 2-week break. At the end of the 3-week break, the participants will be divided into two groups by block randomization method and one group will receive a herbal nutritional supplement mixture (100 ml 30 minutes before training). The other group will drink a placebo prepared with the same texture and consistency as our main mixture, containing an equal amount of carbohydrates (100 ml 30 minutes before training). Then the same performance test will be repeated. At the end of the test also 1 and 2 minutes after end of the test, the participants' heart rate measurement will be taken with a finger-type pulse oximeter and recorded . At the end of the test, perceived exertion levels will be questioned using the Borg scale.

Design outcomes

Primary

MeasureTime frameDescription
Vo2 MaxUp to 1 weekOnce the test is completed, participants' Vo2 max values will be calculated using the formula Vo2 max= Distance covered x 0.0084 + 36.4
Total distance covered in Yo-Yo intermittent recovery test (level 1)Up to 1 weekOnce the test is completed, total distance covered by participants during the test will be recorded in meters.

Secondary

MeasureTime frameDescription
Change between end-test heart rate and heart rate 1 minute post Yo-Yo intermittent recovery test (level 1)1 minutesVolunteers' heart rate was taken immediately after the Yo-Yo intermittent recovery test (level 1) and 1 minute post test. Heart rates were detected by using finger tip pulse oximeter
Change between end-test heart rate and heart rate 2 minutes post Yo-Yo intermittent recovery test (level 1)2 minutesVolunteers' heart rate was taken immediately after the Yo-Yo intermittent recovery test (level 1) and 2 minute post test. Heart rates were detected by using finger tip pulse oximeter

Other

MeasureTime frameDescription
BMIUp to 2 weeksBMI will be calculated. For the calculation of BMI; weight (kg), height (m) will be measured and formulated as follow (weight (kg) / (height (m))2
Waist CircumferenceUp to 2 weeksWaist circumference of the participants will be measured by placing the measuring tape around your middle at a point halfway between the bottom of your ribs and the top of your hips (just above the belly button) and recorded
