Responses of the musculoskeletal and energy systems to a single bout of exercise P1
The musculoskeletal system is two system combined.The first system is the skeletal system.The skeletal system consists of bones, ligaments and cartilage. When doing excercise,our body makes our joints move smoothly by Synovial fluid keeps your joints healthy by providing nourishment for the articular cartilage in your weight-bearing joints. A regular weight bearing excerise routine for example running or resistance , stimulates bone-building cells called osteoblasts to lay down new bone material which make our bones stronger and more dense.The other system is the muscular system. Muscles respond to overload.By working your muscles greater than normal, they become stronger and more resistant to fatigue. exercise such as resistance training can increase the strengh of your muscles while aerobic excercise such as running can will improve muscular endurance.

Energy systems response to acute exercise happens when the exercise is a high intensity. The first response is to use the creatine phosphate energy system. This works in the fast-twitch muscle fibre of the muscles high energy creatine phosphate compounds which are able to break down extremely quickly to create large amounts of ATP. ATP is where we get the energy from to continue and this system only works for the first 10 to 20 seconds of exercise with 100% effort. lactic acid system would provide energy at the start of any activity, even if the intensity is not enough for the aerobic system. If you go out on a jog, most of this is powered by the aerobic system, but the start of the jog is needs to create ATP so that the heart and lungs have enough oxygen and can saturate the blood before the aerobic system can kick in. When the heart and lungs have caught up with the movement of the activity and the intensity is low enough, then the aerobic energy system can fuel the body. In bas scenarios, such as an overweight person...
