Q1) Explain the reason why pre-activity health screening is necessary
Pre activity health screening is used to highlight health problems that may be aggravated by physical exercise. A fitness instructor can then assess and prescribe the correct fitness plan for the individual. Screening takes place in the form of a questionnaire and physiological measurements.
Some health risks looked for by taking part in pre activity health screening are shown by Woolf, May (2006), categorised by risk factor. The first category is known as ‘primary risk factor’s’ which include high cholesterol and high blood pressure. These problems are related to some of highest risks to health such as heart attack when completing exercise . The ‘Secondary risk factor’s’ that may be aggravated by exercise include obesity that is indicated by a body mass index of over thirty kg/m2 and physical inactivity indicated by a failure to reach the minimum fitness standard required. The last category is ‘non modifiable risks’ that is made up of factors that can not be helped such as age and a family history of heart disease. Someone over the age of fifty is also considered to be a factor in this category.
When an individual has completed a health screening questionnaire they may then be asked to take part in further tests in the form of physiological measurements. A persons body mass index may be taken by dividing their weight by height. This can tell a fitness instructor whether the individual is over weight which would need consideration when an exercise plan was produced. An individuals blood pressure may also be taken as a high reading is considered a high risk factor contributing to coronary heart disease. Another test that may be carried out would be the weight to hip ratio which measures distribution of fat
