This study is looking at how different sports drinks affect your physical and mental performance while cycling in warm conditions. Researchers want to see if drinks made with milk permeate, like GoodSport® (a lactose-free sports drink), help you stay hydrated, provide energy, and improve your cycling and thinking skills better than traditional sports drinks like Gatorade® or flavored water. They believe the milk permeate drink, with its specific carbohydrate, sodium, and potassium content, will lead to better results. You might be able to join if you are a healthy, active cyclist between 18 and 55 years old, with a healthy BMI and good fitness level (VO₂max). Success in this study will be measured by how quickly you complete a 5-kilometer cycling test and your scores on a mental alertness test after cycling for about two hours. The current recruitment status is unclear.

Study design

This is an interventional study with a planned enrollment of 14 participants. You will complete five trials, with four experimental trials where you receive different drinks in a randomized order.

What's involved

You will complete five trials, each involving computer-based vigilance and reaction time tests before and after about 2 hours of cycling in a warm environment. During experimental trials, blood, urine, and breath samples will be collected, along with measurements of your body temperature and heart rate.

Compensation

Not stated in the trial record.

Follow-up

Your performance will be measured five minutes after completing the two-hour cycling protocol and the 5-kilometer cycling test.
