I've got the power

How does the body respond to changing energy needs and what are the implications for sports training programmes?

I've got the power is a group of four experiments all about what limits our performance during exercise and how we produce the energy that we require to move our bodies during different types of exercise. In these experiments, the role of aerobic and anaerobic respiration are compared and students investigate how their bodies use ATP for muscle contraction and movement. Using the provided respirometers, pulse oximeters and blood pressure monitors they will explore the physiological effects of exercise on their bodies.

The experiments can be carried out in the science classroom but there is an opportunity for collaboration with your PE department and use of their facilities. Download comprehensive teacher and student resources here.

Measuring blood pressure

The experiments

In these experiments, your students will collect and consider data relating to VO2 max, blood pressure, pulse rate and carbon dioxide production. They will use these measurements to explore how their bodies respond to movement.
