Title: The effect of gender on strength and flexibility

Introduction

The purpose of this investigated is to see the effect of gender on strength and also to see which gender is more flexibility. This investigation took 5 lessons which all data was collected from subjects participating in the tests.

Hypothesis

I predict that males are in general more physically stronger than females, but females are more flexible. I think most males and females have an equal mixture of slow and fast twitch muscle fibers. Gender does not affect the size of our muscles, but does influence the amount. I think that males have more muscles than females. My main aim is to observe which sex is physical stronger but I may test other factors such flexibility to see if it has any effect on strength.

(Scientific background)  Type of Muscle Fiber
one of the most influential factors is muscle fiber type. We have two basic types of muscle fibers, often referred to as "slow twitch" and "fast twitch." Slow twitch muscle fibers are best used for cardiovascular (aerobic) activities. They produce small levels of force for long periods of time and thus are better suited for endurance activities. Fast twitch fibers are best used for anaerobic activities. They produce high levels of force for short periods of time and are best suited for power activities such as weightlifting.

Most men and women have an equal combination of both slow twitch and fast twitch fibers. However, some people inherit a high percentage of slow twitch fibers that enhance their performance in endurance activities, such as long distance runners. Most world class marathon runners have a very high amount of slow twitch fibers. World class sprinters or football players, for example, have relatively more fast twitch muscle fibers. Although both fiber types respond positively to strength training exercises, the fast twitch types experience greater increases in muscle size and strength, and thus may obtain greater and/or faster results from a strength training program.

Gender

Gender does not affect the quality of our muscle, but does influence the quantity. Although men's and women's muscle tissue are characteristically the same, men generally have more muscle tissue than women do because muscle size is increased by the presence of testosterone, the male sex hormone. The larger the muscles, the stronger the person; this is why most men are stronger than most women.

Method

I have carried out 4 tests. All of test was done within 20 minutes; first I was going to measure all male then move to female subjects data but still the male subject were needed in other tests I had to measure the subject gender randomly.

Before all tests subject had to do stretching to reduce the risk of low back pain. Stretching promotes muscular relaxation. A muscle in constant contraction requires more energy to accomplish activities. Flexibility in the hamstrings, hip flexors, quadriceps, and other muscles attaching to the pelvis reduces stress to the low back. Stretching ...
