unit 4 aos 2

Question 1

aerobic power

Answer 1

the max rate of energy production for the aerobic system

benefit: better able to produce ATP under aerobic conditions

sporting example: extended athletic events such as triathlon

Question 2

factors affecting aerobic power

Answer 2

age
muscle fibre type

Question 3

anaerobic capacity

Answer 3

the total amount of energy obtainable from the anaerobic energy systems

sporting examples: an elite level 100m sprint

Question 4

factors affecting anaerobic capacity

Answer 4

lactate tolerance
muscle fibre type (fast twitch fibre)

Question 5

muscular strength

Answer 5

peak force that a muscle can develop

sportingn example: weightlifting

Question 6

Factors Affecting Muscular Strength

Answer 6

speed of muscle contraction
-The more slowly a muscle contracts, the more force it can

length of muscle fibre
-if muscle has slightly
stretched, it can create maximum force

Question 7

muscular power

Answer 7

ability of a muscle or group of muscles to exert a maximum amount of force in the shortest period of time. Power=force X velocity

same factors affecting strength muscular

sporting example: shot put, discuss

Question 8

muscular endurance

Answer 8

ability of muscle or group of muscle to sustain repeated contractions for an extended period of time

sporting example: arms legs and abs in 200m sprint

Question 9

Factors Affecting Muscular Strength

Answer 9

muscle fiber type
-greater percentage of slow twitch fiber, increases muscular endurance

lactate intolerance
-greater lactate intolerance, greater anaerobic capacity

Question 10

speed

Answer 10

the rate of motion (distance/time)

sporting example: 100m sprint

Question 11

factors affecting speed

Answer 11

reaction time
-faster reaction time, greater speed

muscle fiber type
-greater percentage of fast twitch fibre, increased speed

Question 12

agility

Answer 12

ability to change direction rapidly and accurately while maintaining balance

same factors that affect speed

sporting example: evading an opponent in soccer or rugby

Question 13

flexibility

Answer 13

movement around a joint or the capacity of a joint to move through its full range of motion

sporting example: performing gymnastics routines on uneven bars

Question 14

factors affecting flexibility

Answer 14

skin resistance
-skin has lower elasticity than that of ligaments, it can restrict higher ranges of motion

warm up- generally increase the temperature of both the muscles and the structures within the joints

Question 15

balance

Answer 15

the ability of the body to remain in a state of equilibrium while performing a desired task

factors affecting it
the mass of the object

sporting example: standing on one foot whilst shooting a netball

Question 16

coordination

Answer 16

the ability to use different parts of the body together smoothly and efficiently

sporting example: performing ballet movements

Question 17

factors affecting coordination

Answer 17

if you have poor vision or hearing

stage of development also slightly affect coordination

Question 17

reaction time

Answer 17

the time between the stimulus and the first
response

sporting example: reacting to the starters gun in a sprint

Question 18

factors affecting reaction time

Answer 18

intensity of the cue
-greater intensity, shorter reaction time as it is more easily detected

age- the older you are the longer your reaction time becomes

Question 19

frequency

Answer 19

3 sessions a week for improvement

-rest is crucial for a training program as it allows for a positive anabolic effect which is the repair

-not uncommon for athletes working on anaerobic fitness components are training five days a week

-one method is only trained twice a week

Question 20

variety

Answer 20

varying a program can lead to enhanced improvement through different stimulus

-change of scenery
-train with partner

Question 21

progression part 2

Answer 21

-overload should occur when athlete has become accustomed to existing training program
-keeping a training diary can help record when they have become accustomed

-

Question 21

progression

Answer 21

Once a performer becomes accustomed to this new training stimulus, adaptations will
plateau. We need to apply progressive overload to training to ensure continual positive
adaptations.

-one variable should be manipulated at a time
- overload should fall within a range of 2-10%
-any bigger then this will result in injury, stress fractures
