Exercise Science
Skeleton: muscles and everything eels attaches- mamabone – jaw bone ** we are born with soft bones, how many do we have? About 300 soft bones. they turn into 206 adult solid bones-
If we can have a strong core – and deep abdominal muscle called “tranferus abdomenus”- wraps around your core- because it wraps around when it tightens , it tightens up around the spine and gives it a lot of stability- the spine ( a whole lot of bones sitting on top of each other) we don’t want them to fall , and we don’t want them to twist in the wrong way – we want them to be in a neutral position- S CURVE* so every other movement we make can be that much more biochemically correct- forceful , with the least amount of effort-
If you jog your hear t rate goes up, but why? To produce energy. When our heart is beating when sitting, its beating at a relaxed pace- above a resting level but not very hard- at that heart rate your getting enough oxygen to your muscle cells to get enough energy- to write, to hold your head up etc.. more beats per minute, more oxygen getting to your muscle cell to produce more energy- when you heart beats it’s a muscle – the heart beat is a contraction and a relaxation – we are breathing in oxygen ( there has to be communication between the lungs and heart- when we use oxygen in the little muscle cells to make energy one of the buy product is: carbon dioxide- what do we exhale- carbon dioxide***
Every plane of movement has an axis rotation-
Terminology:
anatomical position: palm are facing the class-anterior surface ( that’s how the class is looking at the teacher) what position if her back is facing the class- anatomical position, but looking at it as the posterior perspective
If you took a diagram of a person dividing that person left and right ( anterior) its their left and their right not yours.
Medial- closer to the midline lateral- farther away from the midline. midline always stays the same.
Distil farther is from
