Motivation and Neurotransmitters in Rowers

Overview

The goal of this observational study is to learn how motivation and body chemistry are linked during and after intense exercise in national-level rowers. The main questions this study aims to answer are: Do athletes with higher motivation show different changes in brain chemicals after exercise? How do hormone and neurotransmitter levels change during recovery after exercise? Participants will: Complete a motivation questionnaire called the Inventory of Achievement Motivation (LMI) before the exercise test. Perform a 6000-meter rowing test on an indoor rowing machine. Have blood samples taken three times: before exercise, immediately after exercise, and 1 hour after exercise. Researchers will measure blood levels of testosterone, cortisol, serotonin, dopamine, beta-endorphin, anandamide (AEA), and 2-arachidonoylglycerol (2-AG). This study will help researchers understand how motivation and body chemistry work together to influence performance and recovery in highly trained athletes.

This study explores how motivation and body chemistry are connected during and after intense physical exercise in national-level rowers. Researchers want to understand how psychological factors, such as motivation to achieve goals, relate to changes in hormones and brain chemicals that occur with exercise and recovery. Before the exercise test, participants will complete a motivation questionnaire called the Inventory of Achievement Motivation (LMI). This questionnaire helps identify how strongly a person is driven to perform, overcome challenges, and reach success. After the questionnaire, each participant will complete a 6000-meter rowing test on an indoor rowing machine. This test is designed to produce a high level of physical effort similar to competition conditions. Blood samples will be taken three times: before the test, immediately after the test, and one hour after recovery. The blood samples will be used to measure levels of several hormones and neurotransmitters, including testosterone, cortisol, serotonin, dopamine, beta-endorphin, anandamide (AEA), and 2-arachidonoylglycerol (2-AG). These substances are involved in stress response, motivation, reward, and recovery. Researchers will compare the results from the motivation questionnaire with changes in hormone and neurotransmitter levels. The goal is to find out whether more motivated athletes show different chemical responses to exercise and recovery. Findings from this study may improve understanding of how the mind and body interact during intense training. This knowledge could help athletes and coaches develop better ways to support motivation, performance, and recovery in high-level sports.
