Unit 6- Health Fitness And Wellbeing Flashcards
Factors affecting optimum weight
Bone structure, gender, muscle girth, height
What is optimum weight
Weight at which an athlete performs best at
How does bone density affect optimum weight
Healthier bones tend to weight more because they are denser. Increasing their optimum weight
How does height affect optimum weight
The taller the person the heavier they will be
How does gender affect optimum weight
Men tend to have a bigger optimum weight than women
How does muscle girth affect optimum weight
Muscles are heavier than fat increasing their optimum weight
Definition of sedentary lifestyle
Lifestyle where there is little, irregular or no physical activity
Positive impact of physical health
Reduced risk of obesity, reduce risk of osteoporosis, reduce Rick of high blood pressure and stroke, improved muscle tone and posture, reduced risk of type 2 diabetes
Impacts if you do little physical activity
Obesity, risk of high blood pressure and cholesterol
Positive impacts of exercise on emotional health
Relieves stress and tension, releases feel good hormones (serotonin ), improves confidence and self esteem
Positive impacts of physical exercise on social health
Opportunity to socialise and make new friends, develop life skills such as teamwork and cooperation
Long term effects of sedentary lifestyle
High blood pressure, depression, coronary heart disease, diabetes, risk of osteoporosis
Definition of fitness
Ability to meet demands of environment
Definition of overweight
Weighing more than is ideal for you height
Definition of over fat
Having more than ideal amount of fat
Definition of obese
Weighing significantly more than ideal weight for height, with excess amount of fat
What is a macronutrient and examples
Nutrients you need to consume large amount of. These are proteins, fats and carbs
What is a micronutrient and examples
Nutrients you need to consume smaller amounts of. These are vitamins, minerals, fibre and water
Definition of lifestyle choices
Choices we make about how we live and behave that impact our health
Function of fat
Secondary source of energy
Function of carbs
Preferred energy source, simple and complex
Function of fibre
Bulk to food digestion
Function of vitamin D and C
Vit D - bones
Vit C - immune system
Function of water
Controls temp, transports nutrients , lubricates joints, removes waste
Symptoms if water is not consumed
Thirsty, headache, thickens blood so increases HR, muscle fatigue, confusion/overheat
What is carboloading
Maximises stored glycogen so athletes have more energy, training changes to low intensity to prevent energy being wasted, diet changes to eating high portions of carbs , athletes resist fatigue and can work at a higher intensity for longer
What is timing protein intake
Increases muscle growth and speed up recovery and repair, training causes micro tears in muscles, protein consumed within 2 hours after exercise, this increases protein synthesis which increases muscle mass, increased muscles mass will lead to increased strength
Reason why regular exercise can be difficult to achieve for young people
Lack of money
Lack of transport
Lack of time
Social benefit of regular participation in sport
Make new friends
Teamwork
Importance of a mineral to a sports performer
Calcium is required to keep bones strong which will help prevent fractures
Most likely risk of drinking too much alcohol
Liver damage
2 types of health benefits
Physical and emotional
Advantages of not smoking
More effective gas exchange
Increased lung capacity
Therefore reduced fatigue and a maintained pace
Negative effects of a lack of sleep
Increased blood pressure
Increased risk of obesity
Explain the energy balance equation maintaining a healthy weight
The amount of energy consumed should equal the amount of energy used otherwise weight will be gained or lost
