According to Fredrick Hatfield, the abdominal wall has three major muscles. These are the internal oblique, external oblique and the rectus abdominis. However, other muscles exist for example the transverse abdominis, spinal erectae and muscles in the pelvic girdle. Each of these muscles in the abdominal wall has a specific function and utilizes specific forms of exercise to optimize its functions. In this paper, I will explore the functions of these muscles and how they can be trained in order to optimize their function.
The rectus abdominis, also referred to as the ‘six pack’, is the most prominent of all muscles if well developed. This muscle enhances the flexion of the torso through contraction. This is because it joins the pubic bone to the lower side of the chest thereby flexing the torso towards the hips upon contraction. In order to optimize the function of this muscle, I will use exercises such as leg lifts which allow it to contract in an isometric manner thus stabilizing the pelvis from moving forward. The stabilization of the pelvic region helps to ameliorate back pain. Other exercises that I will use include crunch exercises (moving the torso to the hips) and reverse-crunch exercises which involve moving the hips to the torso repeatedly. However, Hatfield discourages abdominal crunches for obese people as they cause psychological torture. Furthermore, inability to perform repeated movements such as sitting down or getting up is embarrassing for overweight people. This may contribute to or worsen psychological torture.
The external oblique muscle attaches the ribs to the hips and the rectus abdominis. This muscle allows the spine to rotate and twist. Together with the internal oblique, they can be optimized by uti...

- Introduction Scientists, coaches, and athletes have recognized that periodized strength training promotes increase in skeletal muscle size, increase in force, and increase of the regenerating capacity of the muscle cells. Innumerous scientists confirm that nutrition and dietary supplementation can deeply affect molecular and cellular processes that occur in the body during the exercise and the recovery process. This brief review analyzes the potential for performance enhancement through protein supplementation ingestion, and the importance of nutrition education for sports supplement users....

- However, free weight exercises including squats can, in fact, have positive improvements on those with joint-degrading diseases such as rheumatoid arthritis (RA) and osteoarthritis (OA). People who suffer from rheumatoid arthritis have chronic inflammation of the joints, whereas wear-and-tear of the ligaments causes osteoarthritis. A two-year randomized study documented the effects of strength training on muscle strength, disease activity, functional capacity, and bone mineral density in early rheumatoid arthritis....

- How do Muscles Grow. It would seem in the 21st Century there would be a clear answer to this question. Although there is an enormous amount of research on the subject. The answer is not so clear cut. Stem cell research has shed a great deal of light on what can effect positive growth in muscle tissue. (15) The whole complete process on how skeletal muscle tissue responds to increasing loads is not known. The amazing process of skeletal muscle cell hypotrophy is a multi-level consideration, which opens the potential to unlock the key to anti-aging and longevity....

- The hamstring muscles are the collective of muscles of the posterior thigh. This collective of muscles include the biceps femoris, semitendinosus and semimembranosus, which form prominent tendons medially and laterally at the back of the knee. As a group the hamstring muscles produce hip flexion and extension at the knee. They are innervated by the sciatic nerve. Similar to the biceps brachii in the upper extremities, the biceps femoris muscle has two heads – a long head and a short head. The bicep femoris is the most lateral muscle of this group – the common tendon of the two heads can be palpated laterally at the posterior knee.... [tags: Extension, Flexion, Knee, Muscle]

- Cellular Respiration in Skeletal Muscles 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....

The complications after a stroke or a spinal cord injury negatively impact not only the patients’ health, but their quality of life. Therefore, it is important that rehabilitation therapy starts at an early stage after the incidence to enable the patients to adapt to their new conditions and maximise their life. Physical activity and exercise program are one of the most important part of rehabilitation, which help the patients to achieve better health outcomes and lifestyle....

- Introduction Many studies have shown that resistance training improves strength and many other aspects in the elderly population. Although the literature covers a wide variety of such theories, this review will focus on major themes, which will emerge repeatedly throughout the literature reviewed. These themes are: high intensity resistance training improves the muscle mass, strength and hypertrophy, muscle hypertrophy was due to the increase in type I and II fibres and muscle mass and strength gains were slightly more or less the same for both men and women but the was an overall increase in strength adaptations (Williams & Stewart, 2009)....
