P4 - Explain two theories of ageing The Continuity theory (Atchley 1989) stresses the importance of continuing as the person you have always been. This can involve continuing with; interests‚ lifestyles and social contacts from the past. Memories of the past may be important as they can help a person to tell their life story. The important thing is that people can continue to develop an internal sense of self-esteem and self-concept. The Continuity theory suggests that people will have different

Energy Systems The ATP – CP system is primarily used for short duration exercises (about ten to twelve seconds) which involve a high intensity or explosive movements. Energy is stored within the chemical bonds between the Adenosine and the three phosphate molecules. Water is added in the chemical reaction‚ causing one of the bonds to break‚ which releases one molecule of energy from the phosphate. This molecule is used for the muscle contraction. The ATP then turns into ADP as it’s lost a phosphate

Can Cardiovascular Disease be prevented? Heart disease is one of the leading causes of deaths in the world. The primary factors that contribute to heart disease are age‚ male gender and family history. These factors cannot be changed or avoided but there are several steps that can be taken to prevent heart disease. Heart disease is mostly caused by the food we eat. Fatty foods‚ foods rich in sodium‚ smoking‚ stress and excessive alcohol are some of the causes that contribute to a heart disease.

There are 3 energy systems the body uses to create ATP. They are the ATP-PC system‚ the lactic acid system and the Aerobic energy system. Both the ATP-PC and lactic acid systems are anaerobic and therefore do not use oxygen‚ and the aerobic system does use oxygen. When we begin to exercise the first system we would use to create ATP is the ATP-PC system. This system acts by creating ATP from phosphocreatine‚ making use specificially of the phosphate molecule. When energy is used or expended it

P7 describe the three different energy systems and their use in sport activities What is ATP? ATP stands for Adenosine triphosphate. It is often referred to as the ‘‘molecular unit of currency’’. They transport energy within cells for metabolism. One molecule of ATP contains three phosphate groups. How ATP is produced in the 3 energy systems? The first system ATP is produced in is the Phosphagen System. This system is the quickest way to gain back ATP after intense exercise. In this process‚ no

Unit 1 – The Business Environment Assignment: 2 (P3) (P4) Both businesses BP and the BBC have organisational structures. The reason of an organisational is to put in order the workforce to make sure that the organisation is capable to complete vital tasks and goals. Creating a structure with clear roles‚ functions and levels of authority and systems help make sure employees are working together as a team to accomplish everything the business must do.

Introduction In the United States‚ Cardiovascular Disease (CVD) remains the greatest common cause of death. Cardiovascular Diseases‚ also known as the common heart diseases‚ are any conditions that involve blocked blood vessels that can lead to either a heart attack or other heart problems. The common types of CVD are coronary artery disease‚ high blood pressure‚ stroke‚ and arrhythmia. CVD is a major disease that will not show any symptoms until the disease is at its extreme. Yet numerous adults

The European Union Energy Policy: An Initiative in Progress Anna Rulska April 2006 I. Introduction In January 2006‚ Russia cut off supply of gas to Ukraine. The European Union (EU)‚ dependent on gas from Russia‚ delivered through Ukraine‚ realized the full extent of its vulnerability in the realm of energy security and a need‚ more pressing now than ever‚ for a common energy policy. Shortages of energy carry implications not only for domestic producers and consumers‚ but also for

Small Animal Metabolism Materials: 3 Gerbils (8‚ 24‚ 17) Cage Circular Tube 2 Plugs Brown Paper Towel Weight and Balance Soap Solution Drierite Glass Pipette Metal Poker Procedure Our hypothesis for the Small Animal Metabolism lab was that the gerbil will consume oxygen at a greater rate than a mouse because the gerbil is larger in size. To begin this experiment we obtained a gerbil from a specific cage and weighed it on a balance. After we had weighed the gerbil‚ we inserted
