A marathon is considered an aerobic dominant exercise, but higher intensities associated with elite performance use a larger percentage of anaerobic energy. The lactate threshold is the cross over point between predominantly aerobic energy usage and anaerobic energy usage.
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. [1]: 33 [2] [3] Oxygen consumption (VO 2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism.
Other physiological factors affecting a marathon runner's aerobic capacity include pulmonary diffusion, mitochondria enzyme activity, and capillary density. [ 22 ] : 4–5 A long-distance runner's running economy is their steady state requirement for oxygen at specific speeds and helps explain differences in performance for runners with very ...
One of the main differences between the zones is what energy sources they use to fuel the workout. In zone 2, your body primarily burns fats (it can also help burn carbs). This is partly why it ...
Long slow distance (LSD) is a form of aerobic endurance training used in sports including running, [1] rowing, [2] skiing [3] and cycling. [ 4 ] [ 5 ] It is also known as aerobic endurance training, base training and Zone 2 training. [ 6 ]
The aerobic energy system is the one you typically use the most. Whether you’re lying down, walking around your house, or going out for a jog, aerobic exercise uses oxygen to keep you fueled and ...

When non-aerobic glycogen metabolism is insufficient to meet energy demands, physiologic mechanisms utilize alternative sources of energy such as fatty acids and proteins via aerobic respiration. Second-wind phenomena in metabolic disorders such as McArdle's disease are attributed to this metabolic switch and the same or a similar phenomenon ...
