The Importance of Endurance for Physical and Mental Performance
TLDR Endurance is crucial for both physical and mental performance as it enhances various aspects of our biology, allowing our brain to work for longer periods of time. There are four types of endurance - muscular, cardiovascular, mental, and metabolic - each with different protocols and fuel sources, and regular endurance exercise is important for optimal body and brain function.
Timestamped Summary
00:00
In this episode, the host discusses the topic of endurance, including the four types of endurance and the importance of hydration for performance.
06:56
Endurance is the ability to engage in continuous bouts of exercise or movement, and it is vital for both physical and mental performance as it enhances various aspects of our biology, allowing our brain to perform work for longer periods of time.
14:27
Endurance is determined by factors such as neurons, nerves, muscle, blood, heart, and lungs, and quitting is a mental decision influenced by the release of epinephrine in the brain.
21:49
Our willingness to continue or quit is determined by neurons in our brain, and in order to persist, nerves and muscles need glucose, electrolytes, sodium, potassium, magnesium, and carbohydrates.
29:15
There are four kinds of endurance - muscular endurance, cardiovascular endurance, mental endurance, and metabolic endurance - each with different protocols and fuel sources, and everyone should engage in regular endurance exercise for optimal body and brain function.
36:37
Muscular endurance is the ability to perform work repeatedly over time for a given set of muscles and neurons, and it can be improved through protocols such as three to five sets of 12 to 100 repetitions with 30 to 180 seconds of rest in between, focusing on mainly concentric movements and avoiding major eccentric loads.
43:53
Muscular endurance can be improved through compound exercises that focus on isometric holds or non-isometric movements with light eccentric loads, while long duration endurance relies on fuel utilization in the muscles and the activity of neurons in the brain.
50:50
Long duration endurance training is important for building capillary beds and increasing mitochondrial density in the muscles, allowing for more efficient energy utilization and improved performance.
58:05
Anaerobic endurance training involves performing sets of high-intensity exercise with short rest periods, and it helps to improve mitochondrial respiration, increase capillary beds, and enhance the ability of neurons to engage muscles.
01:05:29
High intensity aerobic conditioning involves performing sets of exercise with rest periods in a one-to-one ratio, which can improve aerobic conditioning and energy utilization systems in the body.
01:12:13
High intensity aerobic and anaerobic conditioning can lead to adaptations in the heart and brain, such as increased stroke volume and oxygen delivery, resulting in improved cognitive functioning and endurance.
01:19:26
Breathing through the nose is generally better for performance and efficiency, but as intensity increases, incorporating mouth breathing is necessary; using a gear system of nasal breathing for lower intensity and mouth breathing for higher intensity is recommended.
01:26:06
Warming up the intercostals and diaphragm before endurance work can improve breathing efficiency and oxygen delivery, and increasing speed during exercise can tap into alternative fuel sources and help push through fatigue.
01:32:53
Using multiple fuel sources, such as ketones and carbohydrates, can help tap into new energy sources during endurance exercise, and proper hydration, including electrolytes, is crucial for maintaining work capacity and cognitive function.
01:40:05
Focusing on landmarks during endurance exercise can help improve performance and reduce mental fatigue.
01:46:49
Focusing on visual targets during endurance exercise can help generate more effort and access higher levels of speed and performance.
01:53:24
Combining the protocols discussed in this episode and previous episodes can serve as a useful guideline for getting started or expanding on endurance work, strength work, and hypertrophy work, with the understanding that there will be variation in what people can tolerate and have time for.
