Discuss the relationship between distribution of muscle fibre type and performance. How might exercise training modify or change a person’s fibre-type distribution? There are four different types of muscle fibres: type 1‚ type 2a‚ type 2x‚ and type 2c. “A single skeletal muscle contains fibres having different speeds of shortening and ability to generate maximal force: type 1 (slow-twitch) fibres and type 2 (fast-twitch) fibres. Type 1 fies take approximately 110 ms to reach peak tension when

Muscles are a Band or bundles of tissue in either the human body ‚ or animal body that allow contraction for movement. There are many muscles in the body. It is stated that there are over 650 muscles in the body ‚ and is said that there are possibilities of up to 840. Your whole body is a muscle. You have Muscles in your head‚ arms‚ legs‚ just about anywhere you can think of and as we progress in life and become of age our muscles may grow and get stronger ‚ or may deteriorate.

The macroscopic structures of bone is Compact bone‚ Cancellous bone‚ Epiphysis‚ Diaphysis‚ Periosteum‚ Red bone marrow‚ yellow bone marrow‚ and the articular cartilage (Doitpoms.com). Collagen is a triple helix structured protein that is the most prominent protein in the skeletal system. Bones consist of two distinct types of bone tissue such as cancellous and cortical bone. Cancellous bone is also known as spongy bone and is located

You may be genetically inclined to get it even though you drink milk every day. There are also many other things that contribute to getting osteoporosis‚ like not eating enough calcium‚ doing steroids causes bones to become weak and look like sponges when looking at it under a microscope. Scenarios A‚B‚ and C help to

Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

------------------------------------------------- LIST OF MUSCLE INJURIES Properly functioning muscles perform only one duty‚ contraction. Muscles enable the body to sit‚ to move and to stand upright. They are attached by way of tendons to bones. Their contraction is controlled by electrical signals that can either be voluntary‚ such as when a person decides to stand up‚ or involuntary‚ as with the muscles that expand and contract the chest to control breathing. Muscles are made of thousands of muscle fibers. Knowing the types

(NCBI)‚ depending on the task males or females were more or less resistant for the muscle group being used. Valley Center High School physiology students conducted experiments on muscle size and strength and muscle fatigue. With this in mind‚ the data the students collected from these labs and other sources shows how muscle size and sex have an impact on an individual’s muscle fatigue resistance. First‚ the muscle size of an individual determines how long they can withstand certain types of physical
