This sensor is used to monitor heart rate in beats per minute during and after exercise. It consists of a belt that is worn around the ribcage against the skin, and a SmartQ Heart Rate receiver. The heart rate information is transmitted wirelessly from the belt to the receiver, which can be up to 80 cm apart.
Investigations:
Biology and Physiology:
Monitor heart rate before, during and after vigorous activity
Compare the heartbeat of different individuals: try to include both athletic and inactive people
Monitor the speed at which the heart rate returns to normal following exercise (recovery rate)
What happens to the heart rate when you hold your breath?
Investigate the effects of a mild stimulant such as caffeine in cola or coffee on heart rate.
Check for baroreceptor reflex: that is changes in heart rate for a person when reclined, sitting, standing or moving, caused by the heart pumping blood to different levels.
