Q

What is the interplay of energy systems?

A

Energy systems work together, therefore all active at the start. One system will provide more ATP than the rest so the predominant system is determined by Intensity, Duration and O2 or no O2

Q

What is continuous training (Aerobic)

A

There is a sustained effort with no rest where exercise is required for 20-30min (aerobic TZ). Improvements are made by adapting (Physiological Adaptations). Preseason to increase Cardiovasc. end. general condition, prioritising distance/speed. Near comp. should be comp. pace for well conditioned athletes.

Q

What is Aerobic interval training?

A

Alternation of work and rest periods (W:R, 2:1). More work than rest as short rest=no time to fully recover, maintaining stress. Long in duration to reach (VO2 Max) but short enough to cause fatigue

What is the fartlek training (Aerobic)?

A

Varying the athlete’s speed and terrain by having random intensities (shocks E.S) = teaches body to recover quickly. It is less structured and spontaneous, suitable for sports with alternating speed in game.

Q

Describe the 4 types of stretches

A

Static: Slowly reaching the muscles end range, the held for a period
Dynamic: Progressively faster/continuous controlled movements
Ballistic: Bouncing actions at the end of ROM. Risk of injury bc of the uncontrolled movements. Mimics speed/movement
PNF: Combi of contraction + relaxation. Static followed by isometric contraction then relaxed to perf. next stretch greater. Resistance against force to slowly increase range

Q

What is absolute strength?

A

Maximal force in one contraction

22
Q

What is IRM?

A

Maximum weight in one rep

23
Q

What does Isokinetic mean?

A

The movement is at a constant speed but resistance increases further into the movement

24
Q

What are the types of Strength training programs?

A

Absolute Strength
Speed Strength (Power)
Strength Endurance
Lean Body Mass

25
Q

What is the Absolute strength training program?

A

To build considerable bulk
(Bodybuilding, football player)
80-100% of 1RM
1-5 reps with 3-6 sets
3-5min recovery time

26
Q

What is the Speed Strength (power) training program?

A

Improving speed of contractions (Sprinting)
70-80% 1RM
2-10 reps with 3-6 sets
2-3min recovery time

27
Q

What is the Strength Endurance training program?

A

For lean toned muscles with not much bulk (Tri athletes, rock climbing)
30-50% 1RM
15+ reps with 3-6 sets
1-2min recovery time

28
Q

What is the lean body mass training program?

A

To develop definite increase in muscle size
(Gymnasts, swimmers)
6RM-12RM
10-15 reps with 3-4 sets
2min+ recovery time

29
Q

What are the 4 training methods for strength training?

A

Weight machines
Free weights
Resistance bands
Hydraulic Resistance

30
Q

Describe the weight machine training method

A

Allows isotonic contractions to isolate muscle groups.
Every simple to use but can’t replicate in game conditions such as perf. large quick movements

31
Q

Describe the free weights training method

A

Provides a wide range of exercise/contractions, which mimics natural movements. Individuals must have good technique for it to be effective and avoid injuries

32
Q

Describe the Resistance band training method

A

Often used for rehabilitation but also used to target a range of muscle contractions and movements with a pulling resistance, safer for joints. Also used for injured and recovering athletes. Therefore it is harder to build muscle mass

33
Q

Describe the Hydraulic resistance training method

A

Force is produced by the compression of an air or liquid. It increases resistance as exercise movement speed increases. It’s very expensive but could benefit specific athletes

34
Q

What are the Principles of Training?

A

CROWS TV
Cool down
Reversibility
Progressive overload
Warm up
Specificity
Training thresholds
Variety

35
Q

What is Progressive Overload?

A

Continuously increasing the workload when the body becomes accustomed when improving.
Gradually build endurance + strength as body adjusts to workload. Duration, intensity, frequency, load, reps/sets are manipulated

36
Q

What is Specificity?

A

For an effective result, training must be specific to it’s Energy system (metabolism), movement type and muscle groups

37
Q

What is Reversibility?

A

When an athlete’s gains are lost with a lack of training (detraining effect)
Is considered to maintain frequent and continuous program (Avoid disruption, structuring, preventing injuries)

38
Q

What is Variety?

A

Important to have a wide range of training types, settings, activities and drills to maintain motivation and without boredom

39
Q

What are Training Thresholds (POT)

A
40
Q

What is a Warm up?

A

Activity to prepare physically + mentally for the coming exercises.
Gradually increases HR + reduces injuries (during and after exercise)

41
Q

What is a Cool down?

A

A form of active recovery after exercise to decrease LA levels (minimise muscle soreness)

42
Q

What are the Physiological Adaptations?

A

MR SHOE
Muscle Hypertrophy
Resting Heart Rate
Stroke Volume + CO
Hemoglobin Levels
Oxygen Uptake
Effects on Twitch Fibers

43
Q

What are Physiological Adaptations?

A

Functions that allow the body to function more comfortably, able to be more efficient and capable of more work

44
Q

What is Muscle Hypertrophy?

A
45
Q

What is a Resting Heart Rate?

A

HR when there the body is at rest where a lower RHR = more efficient heart and developed cardiovascular system (increases CO)
Trained: RHR is lower and less energy required to pump blood

46
Q

What is Stroke Volume (SV) and Cardiac Output (CO)?

A

CO: The amount of blood ejected in ONE MINUTE
SV: The amount of blood ejected in ONE CONTRACTION

47
Q

What is the effect of having a higher CO/SV?

A

More Oxygenated blood is sent to muscles in contractions = Less effort needed for the heart as it has become stronger
More systolic pressure (ejection) than diastolic pressure (filling)
Untrained: Not used to the mass amounts of blood being ejected

48
Q

What are Hemoglobin levels?

A

Hemoglobin are molecules found in RBC (250mil/cell) which transport O2 around the body.
Higher H.L = Increase O2 capacity = body can work less to absorb 02

49
Q

What is Oxygen Uptake (VO2)

A

How much O2 the body can absorb to produce energy where the mitochondria uses more O2
VO2 max = Cardiovascular endurance
VO2 max increases force/contractions
Trained: Higher VO2 max = more efficient + powerful movements and endure longer exercises (Myoglobin/mitochondria+ enzyme activity)

50
Q

What are Fast Twitch muscle Fibres?

A

Muscle Fibres that don’t use O2 to create fuel that are used in short+explosive bursts of power.
More developed MF increases ATP-PC supply, hypertrophy, LA tolerance, enables quicker reaction time and generate more force

51
Q

What are slow Twitch Muscle Fibres?

A

MF that uses O2 to generate fuel and allows contraction for longer periods
It increases glycogen stores, mitochondrial function and myoglobin content = work slower but longer to fatigue
