apt therory in touch football
Touch football is a high intensity game involving different skills.The skills range form passing to spiriting down the sideline. The skills that take less then ten seconds are executed quickly and explosive, skills that take twenty too 3 minutes to complete and skills that take more than 5 minutes. 0-10 sec 20 sec-3 min more than 5minFor performer to run, walk, or even blink he's or her's muscles need to contract and release. For muscles to contract and relax a high energy molecule called A.T.P or Adenosine Tri-Phosphate is required.The way this work is that we have two filaments, an actin or a thin filament that is a light in color, and myosin or thick filament, which is dark in color, and a ball liked projections called "Cross Bridges". Cross Bridge Actin Filament Myosin FilamentIn diagram 1 you can see the Cross bridge is attach to the actin and myosin filaments. When the muscle contracts more and more cross bridges attach pulling the actin over the myosin filaments. The more
When this occurs energy is released and the cross bridge attaches to the actin and the muscle contracts. This system takes about 1-2 hours to recover. The muscle will stay contracted cross bridges stay attached until another ATP molecule attaches to the ATP binding site. When you get to a steady state, which is perfect oxygen to energy you can run and run, and not change your breathing pattern. That why in a touch football game they have reserves coming on every 2 to 5 minutes. When ATP binds cross bridges detach and the muscle relaxes, it changes to ADP + P and the cross bridges attach and muscle contracts and so the cycle continues. cross brides attach the stronger the contraction. The way this system works is that CP gives up the Phosphate to the ADP which then becomes ADP + P which will create ATPDiagram 5. Lactic energy systemWhen your exercise goes longer than 15 seconds the lactic acid energy system kicks in to replenish ATP. The way this happens is each cross bridge has ATP binding site. During this breakdown a small amount of ATP is produced allowing the replenishment of ATP for up to 2-3 minutes of high intensity exercise. For the muscle to relax again the cross bridges must detach from the actin. When exercise continues past 5 minutes the intensity level will be much lower. When ATP binds to the cross bridge it undergoes a conformation change and gets spilt to Adenosine Diphosphate Phosphate (ADP + P). The CP system is the fastest way to replenish ATP, because it is a naturally produced chemical so the body can call on it very quickly.
