Physical Education revision

define health
state of physical, social and mental wellbeing where we are free from disease
1 of 26
define fitness
ability to carry out every day tasks without undue fatigue
2 of 26
define strength
ability of body to apply a force against a resistance
3 of 26
define maximum strength
maximum force developed in muscle or group during single maximal contraction
4 of 26
define elastic strength
overcome resistance rapidly and prepare muscle for sequential contraction
5 of 26
define strength endurance
muscle or group undergo repeated contraptions, withstand fatigue
6 of 26
define power
combination of strength and speed
7 of 26
define body composition
relative components of total body mass in terms of fat mass and lean body mass
8 of 26
aspects of co-ordination
general, specific, kinaesthetic differentiation, orientation time and space, reactive ability, syncronisation
9 of 26
lifestyle choice: exercise
healthier, fitter, 1hr per day, cardiovascular diseases, obesity
10 of 26
lifestyle choice: work/life balance
levels of stress, ability to cope impacts health, adrenaline released
11 of 26
lifestyle choices: smoking
cardiovascular disease, cancer, restricts transport of oxygen and narrowing respiratory pathways
12 of 26
components of balanced diet
carbs, protein, fat, water, fibre, minerals, vitamins
13 of 26
simple and complex, stored in muscles and liver as glycogen, complex give slow release of energy (GI) continous supply of energy
14 of 26
source of energy at low intensity, saturated fats found in meats/dairy, fats absorb fat soluble vitamins, layer of insulation, protect vital organs
15 of 26
provide enzymes, growth and repair of cells, manufacture of haemoglobin and myoglobin
16 of 26
help release energy from breakdown of carbs, fats + proteins, promote healthy immune system
17 of 26
whats involved in inspiration
active process, external intercostal muscles, diaphram + during exercise aid of scalene and pectorals minor
18 of 26
whats involved in expiration
internal intercostal muscles, diaphragm + during exercise aid of abdominals
19 of 26
whats tidal volume
volume inspired + expired per breath- inc, during exercise
20 of 26
whats inspiratory and expiratory reserve volume
maximum volume inspired or expired following the end of resting- dec. exercise
21 of 26
residual volume
volume air remaining in lungs at end of maximal contraction- remains same
22 of 26
minute ventilation
volume of air breathed in or out per min
23 of 26
where does gaseous exchange occur
between alveoli and capillaries AND muscle tissue and capillaries
24 of 26
high concentration to a low concentration
25 of 26
control of respiration
inspiratory and expiratory control centre
26 of 26
