The Science

Tyme Wear Vs. Metabolic cart

Our technology measures breathing rate and volume to assess the ventilatory response to exercise. Tyme Wear's breathing data was compared directly with a metabolic cart and was found to be 97% as accurate. From our data we determine the Aerobic and Anaerobic Thresholds, which form the foundation of an individuals cardio-respiratory fitness level. The speed or power when the Threshold events occurred are used to prescribe workouts that target adaptations necessary to improve the individuals fitness level.

Thresholds explained

1. Aerobic (Max Fat Metabolism)

The Aerobic Threshold occurs when your body has reached its maximum Fat burning capacity. At this effort level, your body relies predominantly on Type 1 endurance muscles. Training at this Threshold strengthens your endurance muscles, and improves your body's ability to use fat as a fuel, enabling you to utilize this efficient fuel type at higher effort levels. Training at this effort level also helps improve your VO2max by triggering an adaptation that increases the capillary density in your muscles. This improves your efficiency of delivering oxygen to your working muscles.

2. Anaerobic (100% Carbohydrate Metabolism)

The Anaerobic Threshold occurs when your body transitions entirely to burning Carbs (glucose and glycogen) as a fuel source. This is a result of your body relying increasingly on Type 2 fast twitch muscle fibers. Since our bodies have a limited supply of Carbs, relying too much on them will quickly lead to the end of exercise. Doing intermittent work at and slightly above this Threshold leads to three key adaptations that increases the effort level at which we rely solely on our Carb supply: 1. Our muscles get stronger and more fatigue resistant. 2. We get better at creating, clearing, and consuming Lactate as a fuel source. 3. At and slightly above this effort level, we trigger a phenomenon called Mitochondrial Biogenesis, a process by which our body creates more of our body's power generators; Mitochondria.
