Implementing intentions to drink a carbohydrate-electrolyte solution during exercise.

Area of Science:

• Sports Science
• Exercise Physiology
• Behavioral Psychology

Background:

• Adequate hydration and carbohydrate-electrolyte intake are crucial for athletic performance.
• Psychological strategies can influence fluid consumption behaviors during exercise.
• Implementation intentions are a theory-based approach to behavior change.

Purpose of the Study:

• To investigate the effectiveness of an implementation intention strategy on carbohydrate-electrolyte solution intake during submaximal exercise.
• To determine if this strategy impacts the volume and frequency of fluid consumption.
• To assess the influence of the strategy on physiological hydration markers.

Main Methods:

• Thirty-five participants were randomized into an implementation intention or control group.
• The implementation intention group planned when and where to drink a sports drink.
• Participants completed a one-hour submaximal exercise trial with ad libitum access to a sports drink; intake and urine osmolality were measured.

Main Results:

• Participants using implementation intentions consumed significantly more sports drink volume.
• Higher urine osmolality was observed in the implementation intention group, indicating greater fluid intake.
• The intervention did not significantly alter psychological variables related to intentions.

Conclusions:

• Implementation intentions are an effective strategy for increasing carbohydrate-electrolyte solution intake during exercise.
• This psychological technique can be utilized to promote optimal hydration and fueling in athletes.
• The strategy's effectiveness is demonstrated through increased consumption and physiological hydration markers.
