Assignment on the skeletal system

However it is important for his success. His lungs are made of smooth muscle, these enable him to oxygenate his blood for the muscles. The stronger the lungs the better his cardiovascular performance will be in his game. Also smooth muscle is key for digestion, Wilkinson needs to be physically big and have an edge on his opponents. His smooth muscle in his digestive system is key for the absorption of protein which is a key nutrient for muscle growth. This clearly shows that smooth muscle helps Wilkinson main muscle and enables him to have a physical edge in his game of rugby.

Skeletal muscles help Wilkinson game by working in antagonistic pairs. One muscle relaxes to allow the other to contract and excursuses force. This is helpful to Wilkinson game because it enables him to do things like hand off players. This is made possible by his bicep relaxing and his triceps contracting to make his arm straight. This function is not evident in either cardiac or smooth muscle. Type 1 muscle (slow twitch oxidative) is evident in many Athletes such as long assistance runners, cyclists and long distance swimmers.

This is because these athletes have a high demand of oxygen in their muscles and need their muscles to endure long periods of working time. However in rugby muscle type one is not so evident anymore. Rugby is only 20 minutes of actual working. This means that type 1 muscle would not be the most needed muscle type. Muscle fiber type b (fast glycol fibers) are much more appropriate and useful to Wilkinson as he will mainly need short bursts of speed and power that will make his run more effective.

However muscle fiber type b is based on anaerobic metabolism and therefore only lasts for short periods of time. Therefore Wilkinson would mainly have high amounts of fiber type AAA (Fast twitch fibers), this is because throughout the game his type AAA fibers will not fatigue because they are very resistant and again have a very rich blood supply.
