How Heart Rate During Training Affects Your Endurance
Part of Heart & circulation clinical trials.
This study looks at how your heart rate changes during training to help improve your endurance. If you run a 5K regularly and wear a compatible activity tracker, you may help researchers understand what top performance looks like.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You do cardio exercise 3–5 days a week.
- You can run a 5K (3.1 miles) three separate times over 8 weeks.
- You are between 18 and 65 years old.
- You have a compatible activity tracker (like Fitbit, Apple Watch, Garmin, Oura, Whoop, etc.) and can wear it all the time, even while sleeping.
- You are willing to avoid heavy exercise and alcohol for 24 hours before each timed 5K run.
- You do not have major heart disease risk factors (like current smoking, obesity, high blood pressure, high cholesterol, or prediabetes).
