Why is exercise important?
It improves your health and reduces your susceptibility to diseases and conditions later in life.
-improve lungs and circulation
What are examples of weight-bearing exercises?
-running
-walking
-skiing
-ice-skating
-gymnastics
What becomes less efficient to absorb at age 30-40?
calcium
Where is 99% of calcium stored?
-bones
-teeth
What is osteoporosis?
-brittle bone disease
How can you improve bone density?
Undertake weight-bearing exercise, throughout your life. Increase calcium+vitamin D intake through diet.
What is cardiovascular exercise?
Any vigorous activity that increases heart rate and respiration and raises oxygen levels and blood flow throughout the body.
What are examples of cardiovascular exercise?
-running
-walking
-tennis
-skipping
-swimming
-rowing
What happens during cardiovascular exercise/exercise.
-your heart rate and breathing rate increase to…
-increase to get more oxygen to the muscle cells
-increases to remove carbon dioxide from body
-increase respiration= produce energy
What is recovery time defined as?
The time taken for heart rate+ breathing rate to return to the resting heart rate/breathing rate.
Conclusion of pulse rate experiment.
Exercise increases pulse rate, once finished exercise pulse rate reduces over time to the resting rate.
What is muscle fatigue?
A repeated intense use of muscles leads to a decline in performance.
What can intense activity for muscles result in that hinders your performance?
A lack of oxygen reaching muscles causing build up of lactate in the muscles.
What is lactate?
-lactic acid
-appear= lack of oxygen in your muscles
-muscle fatigue
After you’ve done exercise and our breathing heavily why is your respiration elevated?
To remove lactate and CO2 from muscles.
How do you work out a percentage and find a percentage?
-number1/number2
-x 100
x%/100
What happens during training for athletes?
The efficiency of the lungs to transport oxygen into the bloodstream and the heart to pump blood to the muscle increases.
-pulse rate
-breathing rate
-lactate levels
RISE LESS
What is the average pulse rate for an adult female?
60-100bpm
What is an Olympic athlete’s pulse rate?
30-50bpm
How do you calculate and simplify ratio?
e.g-
2+3=5
£50/5= £10
2:3
2x10=20
3x10=30
£20:£30
e.g- 6:10
3:5
What is an independent variable
The thing you change
What is the dependent variable
The thing you measure
How to explain an experiment well?
What your changing HOW
What your measuring HOW
How to investigate the effects of exercise on pulse rate?
-Heart rate counted by measuring pulse rate for 30secs x2
-60secs of vigorous exercise
-heart rate taken immediately
-heart rate taken every minute until resting
-MEASURED= heart rate/pulse rate
-CHANGED=
