7.2 Sedentary lifestyle Flashcards
Consequence of a sedentary lifestyle
A person who is sedentary is inactive.
Lifestyle is the way a person lives day to day - their typical behaviour.
For example, a person who spends every day switching between working at a desk, sitting on a sofa, to lying in bed would live a sedentary lifestyle.
People who exist in this way run the risk of many physical and mental health issues as a result of this
Some of these include: Weight gain/obesity, Heart disease, Hypertension, Type II diabetes, Poor sleep, Poor self-esteem and Lethargy.
Obesity
Obesity is a condition in which people store a large excess of fat deposits in their body.
It is defined as a body mass index (BMI) of over 30 or over 20% above standard weight for height ratio.
It is healthy for the body to store fat under the skin and around organs for energy storage, insulation and protection of organs.
In excess, for example in instances of obesity, this storage can have a large negative effect on human health.
This is due to the increased mass causing pressure on the bones, and requiring extra exertion to carry the heavy mass.
Obese people also have much lower cardiovascular fitness, making high-intensity or prolonged physical activity challenging.
Obese people are much more likely to suffer from ill health compared to people with a healthy body mass.
Mental and social health as a result of obesity
Obesity can increase the risk of depression and loss of confidence, perhaps relating to body image and concerns about how people will perceive them.
People with obesity may struggle with socialising and meeting new people.
They may struggle to leave their home due to a lack of confidence and mobility issues.
Ill health of obesity
Certain types of cancer, such as colon cancer which has a higher risk due to poor diet, particularly low fibre diets which commonly come from fruit and vegetables.
Increased risk of type 2 diabetes due to high sugar and carbohydrate consumption.
Untreated type 2 diabetes can lead to damaged blood vessels and problems with kidneys, eyes, gums, feet and nerves.
High cholesterol can occur when eating too many fatty foods, this can lead to blockages in blood vessels, such as those around the heart.
This leads to an increased risk of developing heart disease or heart attacks.
Endomorph
Pear-shaped body .
Wide hips and narrow shoulders.
A lot of fat on body on body arms and thighs.
Endomorphs have more muscle and ‘bulk’ and therefore succeed at sports that require brute strength like forward positions in rugby, powerlifting, and heavyweight boxing.
Mesomorph
Wedge-shaped body.
Muscular appearance with high muscle content & low body fat.
Broad shoulders.
Broad chest.
Thin waist & narrow hips.
Mesomorphs have characteristics of both endomorphs and ectomorphs and so have high strength and power but are not weighed down by a large body mass, this makes them suited to sports such as sprinting, swimming and gymnastics.
Ectomorph
Very thin and lean (often tall).
Long arms and legs.
Narrow shoulders & narrow hips.
Not much body fat.
Ectomorphs have a thin, lean body shape which makes them suited for sports that do not require a lot of brute strength but more delicate finesse, such as tennis, high jump or endurance sports such as marathon running.
