Growth & Aging Lab

Growth, development,
and aging.

The Growth and Aging Lab studies how exercise and physical activity relate to human growth, development, and aging. Our research examines physiological responses to training, cardiovascular function, muscle performance, and recovery from childhood to older adulthood.

Building on exercise physiology and applied sports science, we combine intervention studies, laboratory assessments, and population data analysis. Our publications address heart rate variability, vascular function, strength asymmetry, physical literacy, and associations between physical activity and cardiometabolic health.

Research areas

Our research focus

01

Exercise physiology

Physiological responses and adaptations to training, with a focus on exercise intensity, fatigue, and recovery.

02

Cardiovascular & vascular health

Cardiac autonomic regulation, heart rate variability, and vascular responses to exercise across age and sex.

03

Sports science & performance

Muscle strength, asymmetry, fatigue resistance, and training responses in athletes.

04

Physical activity & metabolic health

Relationships between physical activity, metabolic health, and cardiometabolic risk, examined using population data.

05

Lifespan exercise physiology

Physical literacy and activity in childhood, athletic development in adolescence, and exercise and health in older adulthood.

Laboratory equipment

Equipment for assessing cardiovascular function, muscle strength, physical performance, body composition, and bone health.
