Male participants needed for international study on lifestyle and testosterone
- For Staff and Students
- Research participant call-outs
Healthy male volunteers aged 18-60 are needed for a collaborative study between 91²Ö¿â and Portugal that explores how body mass and physical activity affect metabolic and endocrine health. Participants will receive a free, gold-standard VO2max fitness assessment and a Bioelectrical Impedance Analysis (BIA) body composition analysis. This will allow us to study the effects of physical activity on testosterone production, correlating it with male reproductive health.
This project represents a unique international research collaboration between 91²Ö¿â (School of Sport, Exercise and Health Sciences) and the University of Aveiro in Portugal. By taking part, you will have the opportunity to undergo a comprehensive physiological assessment in the state-of-the-art laboratories at the National Centre for Sport and Exercise Medicine (NCSEM), receiving detailed data regarding your own physical fitness and body composition.
What are the benefits of participating?
- Free body composition assessment
- Free VO2 max test
- Refreshment after tests
- Blood analysis (biochemical and endocrine parameters)
What’s involved?
Just two lab visits:
Visit one: Screening and Measurements (~1 hour)
- Info and brief health questionnaires
- Height, weight, and body measurements (No fasting needed!)
Visit two: Fitness Testing and Blood Samples (~2 hours)
- Done after an overnight fast
- Body composition assessment
- Pre- and post-exercise blood samples
- A treadmill fitness test tailored to your age (8-12 minutes)
- Free refreshments provided after!
Inclusion Criteria
We are looking to recruit healthy men aged between 18 and 60 years. A health screen questionnaire must be completed by each participant who volunteers to take part in the study. The inclusion criteria are as follows:
- Biological male
- Body mass index (BMI) between 18.5 kg/m2 and 40 kg/m2
- Non-smoker (vaping is considered smoking in this study)
- No known medical conditions (e.g., diabetes, heart condition)
- Not taking any medication which may affect the study outcomes (e.g., insulin, anabolic steroids, anti-psychotics)
- Not currently dieting and weight stable for three months (< 3 kg change in weight)
- No previous bariatric surgery (e.g., gastric bypass, gastric band, sleeve gastrectomy)
- Not recently donated blood (within eight weeks of visits 1 and 2)
- Able to perform physical fitness assessments such as a treadmill test or handgrip strength test
