increase in muscle pliability‚ increased range of movement and muscle fibre micro tears. Example Answer Increases the range of movement – when we start to exercise the movements of our joints means that synovial fluid starts to secrete within the joints. The fluid becomes less viscous and therefore the range of movement within the joint increases. An example of this in sport is the need for a warm up for a butterfly swimmer. So they can get the full range of movement at the shoulder joint that

First of all we have to defreniate between the musle stenght and muscles power. Musle stenght: Muscular strength defined as the ability of a muscle /group of muscles to contract with maximal force. Muscular strength describes how strong a muscle is or how much force it can exert. Exercise professionals often measure muscular strength by determining the maximum weight a person can lift at one time. There are 2 components to gain muscles strength; 1) The neural component (short-term). 2) The hypertrophic

different types of bone in the human body‚ first we have long bones‚ some being the longest bones available in the skeleton such as the tibia and femur but are also some of the smallest bones such as the metacarpals and metatarsals. The description best suited to long bones would be that they are longer in length than they are in width‚ with epiphysis at either end. (The bones growth plates). The inside of the bone is a spongy like substance known as cancellous bone which is where the bone marrow is found

According to recent studies‚ there are less than two hundred thousand cases of bone cancer per year. There are three varieties of bone cancer which are called chondrosarcoma‚ Ewing’s sarcoma‚ and osteosarcoma. The most dangerous out of the three is Ewing’s Sarcoma‚ which only seventy percent out of one hundred survive after five years of the diagnosis. Chondrosarcoma is also very dangerous if it has progressed further before treatment‚ making it only a twenty-five percent survival rate after five

Animals have three types of muscles; skeletal‚ smooth‚ and cardiac. This lab however is only concerned with skeletal muscle. A special characteristic of skeletal muscle is their ability to contract or shorten via thin (actin) and thick (myosin) filaments (Flanagan‚2017). This gives a striated appearance which is a key distinguishing characteristic between other types of muscle (Flanagan‚2017). Skeletal muscle is also multinucleated. Skeletal muscle needs plentiful amounts of energy to be able to
