NCT07479875
This study investigated the acute effects of ingesting 400 mg of caffeine administered 30 minutes before Brazilian jiu-jitsu-specific strength endurance tests. Experienced athletes completed two conditions, placebo and caffeine, in a randomized, double-blind, crossover clinical trial. Performance was assessed using the dynamic component of the kimono grip strength test (maximum number of repetitions, MNR) and the isometric component (maximum static lift, MSL), both performed with a gi grip. Rating of perceived exertion, adverse effects, and blinding effectiveness were also evaluated.

Background: Sitting volleyball is a sport that relies primarily on upper body strength and anaerobic capacity. In critical in-game skills such as serve and spike, factors such as speed-endurance time and impact power play a decisive role in performance. There are limited studies in the literature examining the effects of low-dose caffeine consumption on these skills. The effects of ergogenic supplements in Paralympic sports have not been sufficiently investigated, and the potential benefits of caffeine on serve and spike performance in sitting volleyball players remain unclear. Purpose: The main purpose of this research was to determine the effects of low-dose caffeine (3 mg/kg) consumption on the serve speed, spike speed and Speed-Endurance performances of elite-level sitting volleyball players. Method: The study was designed using a randomized, double-blind, balanced, and crossover experimental design. 13 elite male athletes from the 2024 Paravolley European Champion Sitting Volleyball Men's National Team participated in the study. Participants were evaluated for serve speed, spike speed, and speed-endurance performances in both 3 mg/kg caffeine (CAF) and placebo (PLA) conditions.

Game profile-based training is a methodology in sports, including football, where training sessions are designed to simulate the specific conditions and challenges that players face during actual games. Coaches analyze individual and team performance data to identify patterns, positions, and scenarios commonly encountered in matches. The training is then structured to replicate these situations, helping players develop the skills, tactics, and decision-making abilities required in real-game scenarios.

The purpose of this study aimed to evaluate the effect of the three-month Chan-Chung qigong program in improving physical functional performance and quality of life in patients with mild to moderate cognitive impairments.A quasi-experimental design was adopted. Subjects were recruited from cognitive impairments outpatients these subjects,41were assigned to the control group and 41 to the experimental group in which Chan-Chuang qigong was administered.
