Which of the following is a technology-based way to gauge intensity level? a) manually measuring distance b) taking the talk test c) using a heart rate monitor d) verbally counting pulse rate

C) Using a heart rate monitor

Explanation:

A heart rate monitor is used to measure the heartbeat during physical activity. Thus, it is a powerful tool for controlling exercise intensity (as intensity increases heart rate) and ensuring training safety. This handset consists of two components. One is a band that surrounds the chest and detects the electronic pulses generated by the heartbeat. The other is a watch that receives signals from the chest strap. Depending on the model, the device displays, in addition to heart rate, other information such as calorie expenditure and oxygen consumption.
