Sentences with phrase «muscle fiber ratio»

(This is because of the change in muscle fiber ratio.

Not exact matches

Fluorescence images were used to quantify the following muscle morphological parameters: total fiber number, single - fiber CSA, total nuclei, the percentage of centrally nucleated fibers (CNFs), and the nuclei / single - fiber area ratio.

(B) The SDH fiber ratio was significantly elevated in EDL muscles from IL - 15Rα — KO mice, indicating a greater number of fibers staining positive for SDH activity.

To quantify these data, we calculated the dark / light fiber ratio, which was significantly elevated in these muscles (Figure 5B).

Morphologically, fast muscles had a greater number of muscle fibers, smaller fiber areas, and a greater ratio of nuclei to fiber area.

The ratio of nuclei per average single - fiber area was also larger in EDL and TA muscles from IL - 15Rα — KO mice, an observation previously noted in slower skeletal muscle (37, 38).

The changes in specific tension (the ratio of strength - to - size) after strength training are not explained by changes in muscle fiber type (Erskine et al. 2011).

Such adaptations include shifts in muscle fiber type, alterations in fascicle length and pennation angle, and alterations in factors at the extracellular and cellular level affecting specific tension, which cause an increase in the strength - to - size ratio.

However, this muscle fiber type composition ratio can vary widely in either direction; some people naturally have quadriceps consisting almost entirely of slow - twitch muscle fibers, while others have mostly fast - twitch fibers.

1) There is evidence that the upper limit of an athlete's VO2 Max is decided (for the most part) by the ratio of aerobic: anaerobic muscle fibers.

4) To recap my points: If you change the ratio of muscle fibers, you change the ratio of fat to sugar burning at which you hit Fat Max, and you increase VO2 Max.

When I design a workout for someone I consider structural balance, all past injuries, strength ratio, muscle fiber type, equipment, exercise history, time, medical conditions, and goals.

While the force exerted by isolated single muscle fibers does not increase after strength training, the specific tension (the ratio of involuntary strength - to - size of the muscle does (Erskine et al. 2011).

Some physiological factors such as the ratio of fast - twitch to slow - twitch fibers in your muscles are genetically determined, but others, such as the speed of nerve impulses, which can be improved by both plyometric exercises and weight training, are only resistant to exercise - induced change.

We all have a mixture of the two basic types of fibers in every muscle, but it's a ratio that may be different between muscles in the same person as well as among different persons.
