Extracts from this document...


Introduction: I am going to investigate the relationship between the size of our biceps muscle and how strong those make are grip. Prediction: I predict that muscles do play a part in giving people more strength and grip. However there are also many other factors to consider such as the size of the fingers, palm and basically the whole hand, as with bigger hands you can have a better grip and apply your full strength. I also predict that the male gender of the class will mostly be stronger than the female gender of the class with a few exceptions. I predict that the person with the biggest biceps will have the biggest grip because as they would have bigger biceps muscles they would have more strength and more muscle fibres. Scientific background and Research on what and how Muscles work: Muscles are protein- rich tissues that are able to contract by up to ten % of their resting length. A ten % movement is quite small, so bones act as levers to magnify this movement. Each bone has at least two muscles attached to it- one to pull in one direction and another to pull in the opposite way. This is because muscles can only pull, they cannot push. A contracted muscle can relax, but it cannot push itself back to its original length. It needs another muscle to do that. Pairs of muscles acting in opposite directions are called antagonistic pairs. All muscles must be paired with other muscles to act as antagonists, as shown below. The muscles we have described so far are skeletal muscles. These are muscles that are attached to bones and are used to move the body. ...read more.

The Mean grip force for the males calculates to be: The mean bicep size, in cm for the males calculates to be: Gradient from Graph : This tells me that a force of 26 N can be applied toeach CM in the biceps of the boys.

Grip accuracy = 10N % error = 10 ( 460 x 100 = 2 % : This proves that Fahim's grip reults are more accurate than his biceps results. % error = 10 ( 560 x 100 = 2 % : This shows me that the grip results are quite accurate but still can be improved. From these two equations one can observe that the grip results were more accurate than my biceps results. The percentage error for both grip and bicep results was quite low making them good results. These results were good enough at proving my prediction correct as these results did prove that the larger the bicep muscle the bigger the grip force. If I was to do further work in this field I would try different age groups, compare sexes and look at their family history and see their variation and genetics. I would also look in to training more and maybe compare people who do a lot of training and people who don't but are quite health and have lots of fat on their skeletal muscles. If I were going to do the experiment again I would firstly improve my method by making everyone come in wit a T-shirt before hand and would get more better and accurate equipment so I can get more accurate results. I would also use my callipers and measure round my forearm as those muscles effect the grip the most. Overall I have enjoyed this experiment thoroughly and have learnt quite a lot about the relationship between biceps and grip with factors like muscles and training coming in to it.
