To reiterate some of his most interesting feats of strength from the video below: 1  Leeâs striking speed from three feet with his hands down by his side reached five hundredths of a second. 2  His combat movements were at times too fast to be captured on film for clear slow motion replay during that time.
Muscles of Respiration. During quiet breathing, the predominant muscle of respiration is the diaphragm. As it contracts, pleural pressure drops, which lowers the alveolar pressure, and draws air in down the pressure gradient from mouth to alveoli.
The main muscle for respiratory inhalation is the diaphragm, which is located deep w â¦ ithin the abdominal cavity. When the diaphragm contracts it opens more space within the chest which allows the lungs to fill with air.he diaphragm is a muscle located beneath the lungs. When it contracts, it expands the lungs causing air to flow into the new space. When it relaxes, air is pushed out as spac â¦ e in the lungs decreases.
