Transcript of 01928 20: Optimum Weight

Optimum Weight Optimum Weight Men and women have different body composition;
men tend to have more muscle and larger bones.
Therefore males and females have different charts to find their optimum weight Gender Bone Structure Body weight and shape are generally passed through the genes! Genetics Optimum Weight in sport Optimum Weight All – be able to explain optimum weight and why it varies.
Most – be able to explain optimum weight and give specific reasons to why it varies. Also explain how optimum weight can affect participation.
Some – all the above and give specific reasons to why optimum weight can affect participation linking directly to the sport. Match up the following Starter: 7;1;1
1;7;1
1;1;7 Most favorable In your groups, think about and write down what 5 factors you think affect people's weight - These are factors outside a person's control Optimum weight is the most favorable weight that is most suited to a general lifestyle or a specific sport Many people need to lose weight to reach their optimum weight. In some sports, such as boxing and horseracing, it is necessary to lose weight rapidly , as boxers and jockeys need to make the weight they are fighting and riding at Losing Weight Taller people are usually, although not always, heavier than shorter people Height This varies widely according to sport the sport being played. Rugby and horseracing have very different requirements.

In rugby, a forward's job is to use muscular strength and power to push the scrum and make tackles in defence. There rugby player's optimum weight is therefore higher than those of a similar height as forwards need a lot of muscular strength, which comes as a result of large muscle girth.

On the other hand a jockey needs to be short in height with small bone structure and a minimum amount of muscle. These factors result in a low weight, which is ideal as it allows the horse to gallop faster The weight a player performs best at Men generally are bigger, stronger and faster, however
which Olympic event's World Record is held by a woman? Bodies have different bone structures, sometimes referred to as frame size. For instance, two men of the same height may have completely different bone structures.

Their frames may be completely different sizes and therefore they will both have different optimum weights because their bones will weigh different amounts. Similar to bone structure, people naturally have different muscle girth which means they weigh more

The BMI charts only take into account the average person's optimum weight, and may suggest a sports performer may be over weight.

In most cases, muscle girth increases with training Muscle Girth Can be a guide to some ones weight for a particular sport or a guide for every day life. Body Mass Index Mens Womens V What are the reasons for the differences in weight between these two performers? How do we lose weight?

Decreasing calorie intake
Increasing calorie expenditure
Both (Dieting plus exercise) Task: Why might Rafael Nadal be heavier than a marathon runner of the same height? Chapter 21- Weight-Related Conditions

Objectives:
All: Be able to identify characteristics and reasons for weight-related conditions
Most: Explain how these conditions may affect physical activity
Some: Be able to explain the terms of weight-related conditions Anorexic Obese Overweight Having weight in excess of normal (not harmful unless accompanied by overfatness) Anorexic: Obese: Overfat: Overweight: A prolonged eating disorder due to the loss of appetite A term used to describe people who are very overfat Having body fat in excess of normal Weighing less than is normal, healthy or required Underweight: Possibly due to medical reasons. Linked with over eating and lack of exercise. If an individual is eating more calories than they are using, they will increase in weight.

This is often beneficial to sportspeople as it means they have more muscle = more strength. (Wrestlers, javelin throwers, weight lifters and rugby players)

If a person is overweight but not involved in activity type then they are less likely to perform well. Optimum Weight: Optimum weight is the most favorable weight that is most suited to a general lifestyle or a specific sport Endomorph

Mesomorph

Ectomorph Match up the following Starter: 7;1;1
1;1;7 Endomorph

Mesomorph

Ectomorph 1;7;1 Having weight in excess of normal (not harmful unless accompanied by overfatness) Anorexic: Obese: Overfat: Overweight: A prolonged eating disorder due to the loss of appetite A term used to describe people who are very overfat Having body fat in excess of normal Weighing less than is normal, healthy or required Underweight: Optimum Weight: Optimum weight is the most favorable weight that is most suited to a general lifestyle or a specific sport Anorexia means 'without appetite' and is expressed as a desire not to become overfat or obese, or a desire to become thin

It is a chronic illness which can be very dangerous. The loss of appetite can lead to extreme weight loss and result in serious lack of nutrition, as well as psychological problems related to obsessions with food and calories Underweight Describes a physique with excessive fat content. Someone described as overweight could be muscular such as a female weight lifter, therefore overfat is used for people with excess fat. Overfat This is people who are very over fat. This is a dangerous condition. People with this condition may find it difficult to exercise which makes losing weight even more difficult. Obesity is often brought on by not having a balanced lifestyle.

Calorie intake far exceeds calorie expenditure 1: Which of the following are the most harmful? OBESE OVERWEIGHT OVERFAT

2: Why is it unlikely that an elite performer will have this condition?

3: Some elite performers, for example rugby players, will weigh more than their ‘expected’ weight, but still be the appropriate weight for their sport. Why will these performers weigh more than expected? Def: A prolonged eating disorder due to the loss of appetite Def: Weighing less than is normal, healthy or required

Being underweight can affect performance. In some sports participants must fit into weight categories or limits.
Race jockeys are deliberately underweight for their height so they can ride at a prescribed weight for the horse.

Both lose weight quickly by exercising and wearing sweat suits and taking drugs called Diuretics (make the person urinate more frequently)

All can cause dehydration which impairs performance Def: Having body fat in excess of normal Def: A term used to describe people who are very overfat
