There are 11 components of physical fitness. 5 of these components are health-related and 6 are skill- or sport-related. For the next several weeks we will define/discuss each aspect and I will give some examples of exercises or drills that will help improve upon each. Of the 5 health-related components‚ we have cardiovascular strength & endurance‚ muscle strength‚ muscle endurance‚ body composition‚ and flexibility. These components are the ones that every individual needs to be aware of and

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.

Introduction Cardiovascular Dynamics and the Cardiovascular Physiology experiments both have multiple goals. The first experiment aims to understand how blood flow‚ pressure gradient‚ and resistance relate to one another. To understand this‚ resistance and contributing factors‚ such as vessel radius‚ viscosity‚ and vessel length must be studied. The effects of vessel radius and stroke volume on the ventricular pump should also examined. The experiment also calls for an understanding of cardiovascular compensation

Elderly and Mental Fitness Exercise is a powerful antidepressant. It can create mental alertness‚ sharper mind‚ and the ability to learn. Movement‚ such as a simple brisk walk can deliver a powerful dose of mind altering hormones to the brain. Researchers at Duke University have shown that exercise can improve the brain functioning of the elderly and may even protect against Dementia. Just as our bodies need physical exercise‚ our mental faculties also need exercise if they are to remain useful

An adolescent brain needs proper nutrition in order to develop and grow. Too little or too much nutrients will affect the nervous system and could possibly delay cognitive development. Under nutrition can cause delay in cognitive growth and development. If the brain does not have the adequate vitamins‚ minerals and micronutrients it does not have the ability to grow brain tissues and conduct nerve impulses correctly. This could lead to inappropriate behaviors and social adaption as well as decreased

The Cardiovascular System CHAPTER SUMMARY The importance of the cardiovascular system cannot be overstated. This is one system that students frequently know something about‚ at least from a plumbing viewpoint‚ but they often don’t completely understand the complexity of the system and the magnitude of its tasks. An essential component of presentation of the material is then to outline in detail the role of the cardiovascular system and its significance to all other body systems. This chapter

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
