PAPER 2 Folded Timgs Flashcards
Some physical benefits of excercise
Efficiency of body organs Strength of bones Body comp Lose weight Fit and sting Life expectancy No suffering Improved components of fitness
Emotional effects
Relieves stress/anxiety - serotonin and endorphins
Boosts self esteem and confidence
Mental challenge
Aesthetic appreciation
Fun and enjoyment
Social benefits
Social skills
Friends and team mates
Food shelter and clothes
Have some worth
Alcohol is a
Depressant which contains chemical ethanol which slows reactions and affects judgment
Effects of smoking on someone’s health
Increase likelihood of cancer
Carbon monoxide goes through blood
Risk of heart disease
Ways alcohol can damage health
Reduction of glycogen levels and slower lactic acid removal
Balance coordination slows down reactions
Heart disease
Being physically inactive decreases the efficiency of coronary blood flow. Physical activity increase levels of high density lipoproteins reducing the cholesterol build up in the blood vessels
High-density lipoproteins
Good cholesterol that counteracts and removers the LDLs from the blood vessels
Low density liloproteins
Bad cholesterol that builds up in the blood vessels
Diabetes
Physical activity increases the level of insulin in the body
Insulin is a hormone that allows the body to use sugars in food as an energy source
Without insulin production our bodies blood sugar levels can become too high
Role of water in the body
Transports nutrients and hormones
Thermoregulatuon
Cushions joints
Lubricants eyes
Symptoms of dehydration
Headaches Tiredness Dizziness Dry mouth Passing small amounts of urine
Dehydration may cause
Dizziness Nausea Fatigue Muscle cramps Increase heart rate Lack of concentration
Carbohydrate loading
Important
Associate to long endurance events
The energy is at its peak
Ensures their energy levels are maintained
Training level reduced Hugh carbohydrates maintained
Achieved by 1 to 4 days of excercise taper
By filling up on carbohydrates
Glycogen (stored in muscle) build up
Protein intake
Mimising proteins break down
Helps build muscle (muscle tears when we excercise)
Stimulates muscles protein synthesis
Power athlete don’t need a legs supply of carbohydrates instead they need to focus on the timing of their protein intake
Affects power athletes because of its role in increasing muscle girth
