However, they did note a progressive trend across heavy, medium, and light loads
for capillary density to increase with decreasing load -LRB--8 %, +4 %, +7 %), while capillaries per fiber displayed a similar, but less convincing tendency (+4 %, +23 %, +18 %).
Not exact matches
After 18 - month - old mice were treated with NMN
for two months, their
capillary density was restored to levels typically seen in young mice, and they experienced a 56 to 80 percent improvement in endurance.
At this point the mitochondrial and
capillary density in your legs are so high that it'll become difficult
for you to put ON weight.
For example, due to higher
density of mitochondria and more
capillaries feeding into muscle, trained endurance athletes rely less on muscle glycogen and plasma glucose and more on fats as an energy source during any given resting or exercise intensity.
However, an example of a factor that affects the ability of your muscles to absorb oxygen would be the extent of the blood
capillary distribution at your muscles (more blood
capillaries means more surface area
for oxygen absorption), and an example of a factor that affects the ability of your muscles to use oxygen would be the mitochondrial
density of your muscles (mitochondria are organelles in your cells that are primarily responsible
for the cellular respiration process that uses oxygen to create ATP energy).
Weight Watchers promotes adequate calcium, fiber and potassium levels
for their roles in bone
density, blood pressure control, muscle building, and the function of blood transport, i.e. arteries, veins,
capillaries.
