简要总结

The goal of this clinical trial is to learn if a lyophilized Cornelian Cherry supplement works to improve anaerobic performance and reduce fatigue in young football players (U14-U19 age group).

The main questions it aims to answer are:

  • Does taking a lyophilized Cornelian Cherry supplement improve participants' anaerobic performance as measured by the Running-based Anaerobic Sprint Test (RAST)?
  • Does the supplement reduce participants' levels of fatigue after strenuous exercise?

Researchers will measure participants' performance and fatigue levels before the study begins and compare them to the levels measured after 1 week of taking the cranberry supplement. This will help determine the effect of the supplement.

Participants will:

  • Take 30 grams of lyophilized Cornelian Cherry powder every day for 1 week.
  • Visit the study center at the beginning and at the end of the 1-week period for checkups and tests.
  • Undergo anthropometric measurements (such as height, weight, and body composition) at the start of the study.
  • Perform a Running-based Anaerobic Sprint Test (RAST) and a fatigue test at the start and end of the study.

详细描述

A balanced diet plays a role in preventing injuries, improving athletic performance, and accelerating post-exercise recovery in adolescents who engage in physical activity. The physiological response to exercise can vary depending on the duration, intensity, and frequency of exercise, as well as environmental conditions. Excessive reactive oxygen species (ROS) production triggered by high-intensity exercise or other stress factors in athletes can lead to oxidative stress and subsequent tissue damage by weakening the antioxidant defense system. Therefore, athletes may need to maintain increased ROS scavenging activity. Additionally, physical exercise can lead to injuries in skeletal muscle tissue, leading to decreased performance. Therefore, strategies to manage exercise-related injuries and post-exercise inflammatory processes may contribute to accelerating exercise adaptation and recovery. Recently, there has been increasing support for the possibility of improving exercise performance through supplementation with fruit-derived polyphenols. Polyphenols are secondary metabolites abundant in plant foods and are divided into four main groups: lignans, stilbenes, and flavonoids. Anthocyanins, a subclass of flavonoids, are found in red, purple, and blue vegetables and fruits. Anthocyanins are known for their antioxidant and anti-inflammatory properties, and therefore, they are thought to prevent adverse physiological effects such as fatigue and post-exercise inflammation, which can potentially occur during exercise. The potential mechanism of action is thought to be related to antioxidant and vascular effects. Turkey is among the countries where cornelian cherries, another fruit with high biological value due to their anthocyanin and other phenolic compounds, are cultivated. Randomized controlled trials have examined the effectiveness of freeze-dried cornelian cherry supplements in various disease groups. Studies have observed positive effects on lipid profiles, as well as parameters related to body mass index (BMI), body weight, waist and hip circumference, and insulin resistance. Another randomized controlled trial has indicated that cornelian cherry supplementation may be effective in accelerating post-exercise recovery in athletes. While the literature has evaluated the effects of various forms of supplementation with fruits high in anthocyanins on sports performance, studies examining anaerobic power and capacity with cornelian cherry supplementation in adolescent athletes are limited. Therefore, the purpose of this study was to evaluate the effects of freeze-dried cornelian cherry fruit on anaerobic performance in adolescent soccer players.

研究组 & 干预措施

Baseline

No Intervention

In order to determine the standard performance of the adolescent football players in the first stage before the intervention, a Running-Based Anaerobic Sprint Test (RAST) was applied to the adolescent football players on a grass field in an open-air environment after a 10-minute warm-up exercise.

Cranberry Intervention

Active Comparator

In the second phase of the study, adolescent soccer players were given 30 grams of freeze-dried cranberries containing 1187 mg/100 g anthocyanins daily for 1 week. To determine post-intervention performance, the adolescent soccer players underwent a 10-minute warm-up exercise followed by a Running-Based Anaerobic Sprint Test (RAST) on a grass field in an outdoor environment.

干预措施: Cranberry Intervention (Other)

结局指标

主要结局

Running-Based Anaerobic Sprint Test (RAST) - Performance Test

时间窗: From enrollment to the end of study at 1 week

The RAST is a test consisting of six 35-meter sprints at maximum speed, with a 10-second rest interval between each sprint. In this test, power is calculated for each sprint using body mass and the resulting performance data (Power = (Total body mass x Distance2) / Time3). The highest recorded number is called maximum power; the lowest number is called minimum power; and the sum of the six sprints divided by six is called average power. Muscle fatigue is assessed using the Fatigue Index (Maximum Power - Minimum Power) / Sum of the 6 sprint times). A lower value indicates that athletes have better muscular ability to maintain their performance without fatigue.
