Introduction of the
‘Burpee’
The burpee is an exercise many love to hate, its lactic acid heavy nature often leaves people shattered and gasping for breath. Many see the burpee as the ultimate full body exercise
As a rugby union player exercises such as the burpee help keep my body in ideal shape and allow me to improve my performance. Strength, body composition and conditioning all play major roles in the efficiency and level of my performance on the field and the burpee enhances all of these components of my fitness. Burpees help ensure that I am strong in my tackling and that I am fit enough to last to the full 80 minutes.
Photographic Analysis of the
‘Burpee’
Phase one:
In this position the athlete stands upright with their feet slightly separated and parallel, the arms hanging easily at the sides with the palms facing the body. When standing still muscles co-contract to stabilise the body and prevent it from falling or flopping due to the effects of gravity. The key joints that stabilize the body are the ankle joint, knee joint, hip joint, vertebral column and the shoulder girdle.
The soleus, gastrocnemius and tibialis anterior contract isometrically to keep the ankle stable at 90 degrees (Teachpe.com n.d.) (The previous reference identified was used to identify key joint types and muscles throughout my analysis).
The knee joint is extended when in the standing position, to stabilize this joint the biceps femoris, semi-mebranosus, semi-tendonosus (hamstrings) and the rectus femoris, vastus lateralis, vastus intermedius and vastus medialis (quadriceps) co-contract isometrically.
The vertebral column of the body remains stable due to the isometric co-contraction of the erector spinae, rectus abdominus and the e...

One of the most important muscles in both a mink and a human are those of the arms and shoulders because of their involvement with movement. One of the primal movers of arm abduction along the frontal plane is the deltoid muscle found in both minks and humans. In both species, deltoid muscles allow for the abduction of the humerus. The next two muscles are the biceps brachii and its opposing muscle the triceps brachii. The biceps brachii consists of two heads, which arise from the scapula and join to form a single muscle that ends upon the upper forearm. The most important functions of the biceps brachii are the supination of the forearm and the flexing of the elbow. The triceps brachii on the other hand extends the forearm in both minks and humans and has three heads as opposed to two in its antagonist biceps brachii (Scott). The origin of the triceps brachii is also from the scapula like the biceps brachii. In a mink, the extensor digitorium originates on the lateral epicondyle of the humerus yet in humans it is present in the posterior forearm and is responsible for extending the phalanges, wrist, and elbow in both species. Anothier muscle with similar functions to the extensor digitorium is the flexor carpi ulnaris but instead it is soley responsible for flexin...
Every day we use our skeletal muscle to do simple task and without skeletal muscles, we will not be able to do anything. Szent-Gyorgyi (2011) muscle tissue contraction in rabbit’s muscles and discovered that ATP is a source for muscle contraction and not ADP. He proposed a mechanism to cellular respiration and was later used by Sir Hans Krebs to investigate the steps to glucose catabolism to make ATP. In this paper, I will be discussing the structure of muscle fibers and skeletal muscles, muscle contraction, biomechanics, and how glucose and fat are metabolized in the skeletal muscles.
This report will explore the structure and function of skeletal muscle within the human body. There are three muscle classifications: smooth (looks smooth), cardiac (looks striated) and skeletal (looks striated). Smooth muscle is found within blood vessels, the gut and the intestines; it assists the movement of substances by contracting and relaxing, this is an involuntary effort. The heart is composed of cardiac muscle, which contracts rhythmically nonstop for the entire duration of a person’s life and again is an involuntary movement of the body. The main focus of this report is on skeletal muscle and the movement produced which is inflicted by conscious thought unless there is a potentially harmful stimulus and then reaction is due to reflex, as the body naturally wants to protect itself. Skeletal muscle is found attached to bones and when they contract and relax they produce movement, there is a specific process that the muscle fibers go through to allow this to occur.
During dynamic activities, the bony congruity of the joint surface and the acetabular labrum limit the magnitude of translation forces, while the ligamentous and muscular structures control rotational forces at the hip joint. Physiological features of the joint cartilage and synovium manage the residual forces and joint reaction forces that
Although the two main proteins, actin and myosin, that make the contractile nature of muscles are the same, their arrangement coupled with other proteins subsequently causes the overall structure to differ in many respects. The main function is essentially the same in every muscle type, however as the structure varies the function and resulting contraction is different. the way they contraction occurs is different. This shows how structure is adapted to function and vice versa.

It was also observed that there was significant difference between groups, where lipid content was ~25-50% higher in muscle from type 2 diabetes and obesity than normal subject, Lipid content intensity in muscle was ~40-50% higher in obese and type 2 diabetes than normal subjects.
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
This skill involves jumping in the sagittal plane about the transverse axis. It consists of hip, knee, ankle, and shoulder joints. In the preparation phase in propulsion, the subject has flexed knees and hips which will need to be straightened by the strength of their corresponding joints such as the hinge joint at the knee joint. The hip joint is a ball and socket joint that bears the body weight and allows for jumping motion. During th...
The main objective of stability training is to increase your muscular endurance and of your stability, while at the same time developing better communication between your nervous system and muscles.
First let’s go over four very important factors of the human muscular system. First being the primary function of the muscular system is movement for the body. The nervous system communicates with the muscular system, resulting in movement. Second is the five major properties of the muscular system beginning with 1) our muscle being excitable or irritable. 2) Our muscles are contractible. 3) Our muscles are extensible. 4) Our muscles have elasticity. 5) Last, our muscle system is adaptable. Third, there are five types of muscle movements. 1) Adduction, movement towards the body. 2) Abduction, movement away from the body. 3) Flexion, “movement in the anterior-posterior plane that reduces the angle between the articulating elements.” (Martini, F 230). 4) Extension, “occurs in the same plane as flexion, but it increases the angle between articulating elements.” (Martini, F 230). 5) Last is rotation. Fourth, there are three main
Bulimia is a disorder centered around an individual’s obsession with food and weight. This obsession involves eating large quantities of food, feeling guilty about the food consumption, and taking drastic measures to prevent caloric/fat absorption. Measures vary with each individual and include one or all of the following: forced vomiting, abuse of laxatives or diuretics, or excessive exercise. This disease affects one to three percent of adolescent and young women in the United States, and bulimic behaviors are displayed by ten to twenty percent of adolescent and young women in the United States (http://dcs.engr.widener.edu/galla/gal la.htm).
The first basic function of the muscular system is movement, which is carried out by the skeletal muscles. The primary function of the skeletal muscle is to produce voluntary gross and fine motor movement. This set of voluntary muscles provides the forces that enable the body to move. A skeletal muscle links two bones across its connec...
The muscular system is a very important part of the human body. It has many components and functions, and is the source of the body’s movement. There are roughly 650 muscles in the human body and are different types of muscles. Muscles can either be voluntary or involuntary which means controlled or uncontrolled movement. Muscles have many reasons and in this paper you will widen your knowledge of muscles and their functions as well their diseases and how they help maintain the body.
