Paper 2 Flashcards
4 parts to a training programme
1) plan (aim+design)
2) develop
3) monitor
4) evaluate
Physical health benefits of exercise
Stronger bones (reduced chance of osteoporosis) Reduced chance of stroke and CHD (low blood pressure) Less chance of obesity (burn fat)
Why is low cholesterol good
Blood vessels are less restricted
Negative physical effects of of exercise
Heart attack/stroke (overexertion)
Overuse injuries
Less effective immune system
Positive emotional effects of exercise
Stress relief (serotonin increased and take mind off problems) Competition (win feels good) Reduce boredom Aesthetic appreciation Increase in self-esteem/confidence
Negative emotional effects of exercise
Depression may be caused by injury
Positive social effects of exercise
Meet friends/make new friends
Less involvement in antisocial behaviour
Improve cooperation (team work)
Negative social effects of exercise
Less time with family if professional
Lifestyle choices that effect sporting ability
Diet Anorexia Obesity Lack of nutrients Low activity levels Work/rest/sleep balance Alcohol/smoking/drugs
Examples of diseases caused by lack of nutrients
Rickets- lack of vitamin D/calcium
Scurvy - Lack of vitamin C (tiredness)
Osteoporosis- lack of calcium
Sedentary lifestyle
Limited or no physical activity
What is a possible reason for an increase in number of people living a sedentary lifestyle
Where there’s limited or no physical activity
Health risks of sedentary lifestyle and why they are caused
Heart disease (high blood pressure+low cholesterol)
Type 2 diabetes - (overweight)
Obesity - (reduced metabolic rate+inactivity)
Osteoporosis (lack of weight bearing)
Loss of muscle tone/poor posture
Poor fitness
Depression
Define overweight
A person weighs more than expected for their height and sex
Define overfat
More body fat than you should have
Define obese
Very overfat
BMI of more than 30
7 nutrients we need in our diet
Carbohydrates Vitamins Water Protein Minerals Fibre Fats
Define a balanced diet
Eating a variety of food from all different groups in the correct proportions
Define nutrient
Something that gives nourishment to the body
What are the macronutrients
Carbs
Fats
Proteins
Why are carbs important
Provide us with energy for aerobic and anaerobic
Why are fats important
Easily stored and give energy for aerobic respiration
Why are proteins important
Aid muscle growth and repair (hypotrophy)
What are micronutrients
All vitamins and minerals
What do vitamin D and calcium do
Vitamin D - helps body absorb calcium
Calcium - keeps bones strong
What are 2 important things in the diet that are not nutrients
Water and fibre
What are water and fibre needed for
Water - prevents dehydration
Fibre - aids digestive system
Define optimum weight
The ideal weight for a person to be
What does optimum weight depend on
Bone structure
Height
Sex
Muscle girth
What is dietary manipulation
Planning exactly what you eat to help optimise performance
What is important about protein intake
It should occur after activity to help maximise repair of muscle tissue and aid growth during training
What is carb loading
Increasing carbs stored as glycogen in the muscles to provide energy for performance
Eating carbs 1-4 days before activity
Reduce activity in this time
Reduce fibre intake
Why is water crucial for a sports person
To stay hydrated as water is lost through sweat otherwise
Muscles cramp, fatigue and nausea could occur
What is classification of skills recorded on
A continuum
