Although pedometers are widely used to measure physical activity by counting the number of steps a person takes, they canât measure exercise intensity. In the lab, exercise intensity is commonly determined by measuring the amount of oxygen taken in by the body during exercise, known as oxygen uptake.
There is a direct correlation between your exercise intensity and the amount of thyroid hormone you produce. In other words, low thyroid levels are associated with low-intensity exercise, and as you increase your intensity level, your thyroid levels increase too. Exercise performed at the anaerobic threshold causes prominent changes in hormone values, and they continued to rise up to 90% of max heart rate [2].
