Participants required for a new study

The effect of three days of reduced sleep on cognitive and physical performance among recreational athletes

Purpose and value of study
There is a growing interest in sports science of how sleep affects athletic performance. However, studies that have investigated the effect of sleep quantity on exercise performance have produced mixed findings. 

The purpose of this study is to explore if a small reduction in sleep influences cognitive or physical performance.


Who can take part in the study? 

•    People aged between 18-40 years who perform at least 150 minutes exercise per week, which includes some high intensity exercise (e.g., team sports, tennis, interval training). 

Who is organising the research?
Paul Hough (PhD candidate at St Mary’s University, Senior Lecturer at Oxford Brookes University)

What does the research involve? 
You will be asked to wear a small wristband throughout the study. The band measures movement and estimates when you are asleep and awake. It also calculates your readiness to perform. 

You will be required to report to the human performance laboratory at St Mary’s University on three separate occasions between 1-5pm. 

During each visit your height, body mass and body composition will be measured using a stadiometer and specialist scales.


You will then complete the following tests: reaction time, manual dexterity, subjective scales, muscle force, and a (5x10 second sprints on a cycle ergometer. During the reaction time test, you might be asked to wear a head cap that measures electrical brain activity (this is optional). 

Are there any benefits in taking part?
The tests used in this study are not usually accessible outside of research and professional sporting organisations. You will gain an insight into your:  

•    habitual sleep patterns (duration and quality) 
•    maximum strength (mid-thigh pull)
•    peak lower body-power (cycling sprint) 

Collectively, the data will enable you to understand how sleep influences your mental and physical performance.
