Biology coursework Hypothesis: I predict that the longer you are contracting the peg the slower you will become when doing so‚ this is because of muscle fatigue. And when taking two seconds between each contraction the speed will decrease at a much slower rate than if you are doing the contractions as fast as you can. The science backing up my hypothesis: The higher the intensity of any type of exercise the more lactic acid is produced in a certain amount of time‚ this is by a means of anaerobic

build muscle strength. Unlike protein‚ creatine does not help to repair muscles or build muscle but allows the body to have more energy to work harder. Creatine is naturally found in the body and in foods such as seafood and red meats.1 Many studies have been conducted in order to scientifically show whether or not creatine really works. A common misconception is that creatine stimulates muscle growth. Creatine is not a steroid‚ however‚ it is a useful supplement that can help to increase muscle mass

shivering which generate heat through muscle contractions. 3. Thermoregulation‚ a homeostatic process‚ is responsible for initiating and controlling the physiological responses helping to keep Joel warm. His body temperature is being monitored by his hypothalamus which has triggered his sympathetic vasomotor center to initiate vasoconstriction of the dermal blood vessels in his extremities. The nervous system is also alerted by the hypothalamus to induce muscle contraction in order to generate internal

The Muscular System: Muscle Metabolism 1. List the three roles of ATP in muscle contraction: 1.Energize the power stroke of the myosin cross bridge. 2.Disconnecting the myosin head from the binding site on actin at the conclusion of a power stroke. 3.Energizing the calcium ion pump 2. The potential energy in ATP is released when the terminal high-energy bond is broken by a process called Write the end products of this process: ATP (+ H2O) ______ADP___________ 3. Rebuilding ADP into ATP with

The arterioles in the skeletal muscles dilate‚ which increases blood flow to the muscles and leads to an overall drop in peripheral resistance. At the same time there is vasoconstriction in the vessels supplying blood to the abdominal organs and kidneys. This makes sense: if an individual was running from an attacking lion‚ digestion wouldn’t be a high priority while the muscles involved in escape would be. Another cardiovascular response to exercise is

bodybuilding supplements is creatine. Creatine monohydrate is used to increase muscle fullness and body mass. It also helps in shortening the recovery time after an intense workout. Creatine can cause your muscles to retain water‚ which can lead to dehydration in some people. Also‚ there might be up to a five pound weight gain during the first week. There are no major known

ASSIGNMENT BRIEF Scenario You are a ‘gifted and talented’ athlete who is taking part in some training and your coach has insisted that you understand more about HOW your body works during exercise to maximise your training and ultimately your performance. You will participate in some practical activities and look at readings to interpret what the body systems do in response to becoming active. How we physiologically change from being at rest to being active. Criteria reference To

Inflammation- Inflammation is the bulging of skin‚ organs‚ or other body parts due to fluid buildup caused an injury. The fluid rushes to the injured area and that is what makes the puffiness. 2.

circuit training and types of S&C. Resistance training is a training method that uses a resistance to the force of muscular contraction (concentric i.e. shortening‚ eccentric i.e. stretching and isometric i.e. no change in length). Stretch shortening cycle- when a muscle is stretched before its contracted is produces a more powerful contraction e.g. CMJ Slow-twitch muscle fibres are fatigue resistant but don’t contract very forcefully or rapidy. Uses oxygen. Fast twitch fibres contract rapidly
