What would happen if we had no ankles? Ankles are crucial to our movement and play a huge part in moving our feet and walking. The ankle is a large joint made up of three main bones. These three main bones are the tibia, the fibula and the talus which all join together to make the ankle joint which helps control movement in your foot.The ankle contributes to a lot of lower limb stability which allows humans to run, jump and perform various other activities which require moving.The ankles…

Introduction Some of the most important organs in the human body are muscles. Muscles usually make up 30-50% of the body and are responsible for producing skeletal movement, maintaining body position, and regulating body temperature. In a lab, the process of muscle contraction was investigated by exploring the sliding filament theory. An experiment was conducted to determine whether muscle length played a role in the amount of force a muscle produces. In order to fully understand how a muscle…

Power Power is a relevant and one of the most important skill-related components of fitness to the performance of a javelin throw. Muscular power is the ability to combine strength and speed in an explosive action and this is shown in a javelin throw. There are two types of powers, speed-dominated power, which is power generated through a greater emphasis on speed and is essential in activities such as sprinting and throwing which javelin includes. As well as strength-dominated power, which is…

Research In 1903, Robert Osgood, a US orthopedic surgeon, and Carl Schlatter, a Swiss surgeon, concurrently described the disease that now bears their names. They found a pattern in which teenagers who are still growing often experience knee pain and inflammation in the area just below the knee and they called it Osgood-Schlatter disease. Teens experience symptoms of this while doing athletic activities or doing some regular exercise like climbing stairs. They feel pain in their knee,…

Due to the fact that one of the two ways to increase the strength of a muscle contraction is to increase the frequency at which the motor units fire in order to create a summed effect, it is expected that the shorter the time interval between consecutive stimuli, the greater the force of contraction. If there is a greater amount of time between the stimuli, the muscle would be able to relax before the next stimulus is fired. However, as that time decreases, the individual twitches begin to…

One of the first things to consider is that more is not always better. Whenever many of us first start out exercising with push-ups, we tend to overdo it and this can lead to a number of different problems. One of the most common problems that you're going to experience because of over exercising is burnout. Both are likely, this type of routine is only going to last four days before you are finished. Another problem that can occur is injury, and these are very common whenever you're first…

I have a strange infatuation with diseases. I love to see diseases, analyze them, understand the symptoms that define them, but most importantly, discover if and how the ailment can be cured. One disease that has recently become a focus in my life, is one I have personally entitled African American Dystrophy; a disorder characterized by the weakening, degeneration, or abnormal development of a people. It is a disease that has been metastasizing this country since I was young. Spreading rapidly,…

You're not training hard enough If you don't train intensively, your muscles will not grow, that's a fact. If you think doing 20 minutes of arms, 20 minutes of chest, 20 minutes to develop your leg muscles, you are completely wrong. Use compound movements, train a big muscle intensively per session and you'll start seing results! You don't rest enough What you do at the gym ensures that your muscles grow. But this development takes place only when you rest or sleep. It is the growth hormone…

Leukocytes function is to protect the body from infectious diseases. Erythrocytes function is delivering oxygen to organs and cells via the bloods circulatory system. Platelets function is to clot blood so that it prevents any blood loss. Firstly the main protein is called hemoglobin, functioning to transport oxygen to the entire body including every tissue from the lungs, then transporting c02 back to the lungs…

McArdle syndrome, also known as glycogen storage disease type V (GSD V) is a rare genetic autosomal recessive disease of the muscle tissue or myopathy caused by the body’s inability to produce phosphorylase; “an enzyme that catalyzes the formation of glucose-1-phosphate from glycogen.” (Taber’s Cyclopedic medical Dictionary). Without it, sugar or glycogen stored in the muscles cannot be used to produce energy resulting in fatigue, severe muscle pain and cramping after momentary exercise.…
