Core 2 Critical Question 2 Flashcards
What are the health related components of fitness
BCMMF - Body composition, cardiovascular endurance, muscular strength, muscular endurance and flexibility.
Body composition
Refers to the percentage of fat as opposed to lean body mass in a human
Ectomorph
Skinny light build
Mesomorph
Build is compact and muscular.
Endomorph
soft round build, high proportion of fat tissue.
Cardiovascular endurance
The circulatory and respiratory systems ability to supply oxygen to the body to remove carbon dioxide and waste products during sustained exercise.
Muscular strength
The ability to exert force against a resistance in a single maximal effort. One rep
Flexibility
The range of motion about a joint or the ease of joint movement.
Muscular endurance
A measure of the ability of the muscle to contract repeatedly over a period of time, thereby delaying fatigue.
Skill related components
Coordination, agility, reaction time, power, balance and speed
Coordination
Coordination is the ability to harmonise messages from the senses with parts of the body to produce movements that are smooth, skillful and well controlled
Agility
The ability to move the body from one position to another with speed and precision.
Reaction time
Reaction time is the time-taken to respond to stimulus.
Power
the ability to apply force as quickly as possible resulting in dynamic bursts of movement.
Balance
ability to maintain stability and relies on equal distribution of weight.
Speed
Speed is the pace the athlete performs a task or the ability to perform movements quickly.
Aerobic
Aerobic training targets an athlete’s endurance capacity by targeting improvement in the delivery of oxygen to working cells.
Anaerobic
The level of intensity is much higher, and the effort period is much shorter than aerobic activity.
FITT
Frequency (how often), Intensity (how hard?), Time (How long) and Type (What?).
Heart rate
The number of times the heart beats per minute. When we begin to exercise our heart rate increases.
Ventilation rate
Number of breaths per minute
Stroke volume
The amount of blood coming out through the left ventricle per beat
Cardiac output
The amount of blood coming out of the left ventricle per minute. Calculated by SVxHr
LActic levels
A measure of how much lactic acid in blood.
Lactate levels rise greater in aneoribic or shorter intervals of exercise
