Twenty years ago sports gadgets were typically limited to fancy wristwatches. Physiological research was typically done in the lab with treadmills and expensive equipment that required lots of wires and measuring devices.
Today the gadgets are less expensive, more portable, and “reasonably” priced for the serious athlete.
For example, consider the Pear Square device by Pear Sports.
The biofeedback training system costs $250 and includes a foot pod, wireless heart rate sensor and strap, and earphones with a retention system. The user can select music and a training program for their workout. From there the heart monitor and foot pod measure performance. The interactive audio coaching or software provides commentary about whether the runner is meeting the goals (heart rate, pace, time, and distance) of their training plan.
Its simple to use.
