NHE Exercise Science/Physiology File: #82 [Power Endurance]


Power endurance is the ability of a muscle group to contract at near maximum, for a greater period of time. The more power endurance one possesses, the longer that individual will be able to sustain the action or movement(s). Power endurance training uses moderate loads of 50-70% 1RM, lifted for 15 to 30 repetitions. Because this can lead to a significant build up of lactic acid (milk acid- the conversion of pyruvic acid when oxygen is insufficient within the muscle cells.) rest periods between sets are long (5-7 minutes) and a minimum number of sport-specific exercises are used (about 3-4). Exercises are often performed one set after another (circuit). Alternating exercises allows adequate recovery and sufficient time for some lactic acid to metabolize. If rest intervals are too short and sets are completed while the muscles are still fatigued, the result will be hypertrophy (increased muscle mass) rather than power endurance. Sets should not be completed to failure but should end while repetitions are no longer powerful and rhythmic.

What is Metabolism anyway?

Metabolism is the sum of chemical and physical reactions that occur within the body, and more specifically, is an energy producing activity that occurs within the cells of all living organisms. Metabolic activities convert chemical energy, from ingested food, into mechanical energy or heat, otherwise known as calories. Metabolic activity is required for the sustenance of life, growth, and development. All metabolic reactions are initiated by enzymatic activity. Enzymes are specific proteins, with catalytic properties, capable of acting independently. These catalysts induce chemical reactions, within the body, while maintaining their original properties. The basis of metabolism involves two very specific processes: anabolism and catabolism. Anabolism is the conversion and synthesis of smaller molecules and constructing them into larger compounds. Catabolism is the breakdown of larger substances into smaller, more usable molecules. Metabolic activities help to regulate and maintain the body and keep it functioning properly.

The metabolic pathway begins with a series of individual reactions that result in the formation of an end 'product'. Catabolism is the first, of the two metabolic processes, that occurs within the body. This involves the breakdown of nutrients, to produce energy within the body. Most food components are macromolecules. Food macromolecules are biological chains of 'repeating' smaller molecules linked together called polymers. Polymers are comprised of proteins, carbohydrates, nucleic acids, and fats. The repeating units, forming macromolecules, are called monomers (building blocks). Proteins, carbohydrates, and lipids constitute the main substrates for digestive enzymes. These substrates are catabolized and released as free energy, known as ATP (adenosine triphosphate). Upon the breakdown of nutrients, the body uses, and stores, the energy converted during the catabolic process. This energy can now be used to form larger molecules by the covalent bonding of electrons, protons and free energy. Energy used during anabolic activity comes at the expense of free energy converted through catabolic activity.

Rheumatoid Arthritis Information:
RA is a long-term disease that leads to inflammation of the joints and surrounding tissues. It can also affect other organs.

Causes, incidence, and risk factors:
The cause of RA is unknown. It is an autoimmune disease, which means the body's immune system mistakenly attacks healthy tissue. RA can occur at any age, but is more common in middle age. Women get RA more often than men. Infection, genes, and hormone changes may be linked to the disease.

Symptoms:
RA usually affects joints on both sides of the body equally. Wrists, fingers, knees, feet, and ankles are the most commonly affected. The disease often begins slowly, usually with only minor joint pain, stiffness, and fatigue.

Joint symptoms may include:
Morning stiffness, which lasts more than 1 hour, is common. Joints may feel warm, tender, and stiff when not used for an hour. Joint pain is often felt on the same joint on both sides of the body. Over time, joints may lose their range of motion and may become deformed.

A Lesson in Joint Support

Glucosamine is a combination of glucose and amino acids, known as “amino sugar”. Oral glucosamine is commonly used for the treatment of osteoarthritis. Since glucosamine is a precursor for glycosaminoglycans (a component of joint cartilage), supplemental glucosamine may help to rebuild cartilage and treat arthritis. Since the body's natural glucosamine is used to make and repair joint cartilage, incorporating a glucosamine supplement is thought to help repair damaged cartilage, by augmenting the body's supply of glucosamine. Glucosamine is not available in any primary food source. A typical dosage of supplemental glucosamine is 1,500 mg -2,000 mg per day.
 
Chondroitin Sulfate is a major component of ECM (extracellular matrix or connective tissue), and is important in maintaining the structural integrity of tissue. Chondroitin sulfate is a major component of all cartilage. Loss of chondroitin sulfate will cause the development of osteoarthritis. A typical dosage is 800 mg –1,200 mg per day.
 
Methylsulfonylmethane, also known as MSM, is a naturally occurring sulfur compound found in fresh fruits and vegetables, milk, fish, and grains. It is commonly used to treat inflammation, fibromyalgia, arthritis, and joint pain. In addition, it can strengthen joints, balance blood flow, and improve muscle contraction and mobility. A typical dosage is 500 mg -1,000 mg per day.?

NHE Anatomy File #331: The Menisci

The menisci are made of tough cartilage. The medial meniscus is on the inside of the knee and the lateral meniscus rests on the outside of the knee. These menisci function to distribute body weight across the knee joint. The menisci consist of semilunar fibrocartilage, partly filling the space between the femoral and tibial bones.

Primary Functions:
1. To act as shock absorbers.
2. To increase the stability of the knee joint.
3. To provide a thin layer of synovial fluid, providing nutrition to the articular cartilage.
4. To aid in the mechanical functions of the knee joint.
