Q

Protocol for the Sargent jump (explosive strength fitness test)

A
  1. Person stands with arm stretched straight above them -assistant measures reach
  2. Person the jumps -assistant records their reach when they jump
    * stages of jump: 1. Eccentric contraction (lengthen) when bending 2. Hold-no movement 3. More powerful concentric contraction (shorten) when jump*
  3. Repeat 2 more times and find an average
  4. Reach is worked out by ‘jump reach - original/standing reach’

Q

What is dynamic strength often referred to due to predominantly using what energy system

A

Often referred to as ‘anaerobic capacity’ as it predominantly uses the lactic acid system for energy production

Q

Protocol of the wingate test (fitness test for dynamic strength)

A
  1. Warm up for 10 mins
  2. Athlete pedals as fast as possible without any resistance
  3. After 3 seconds a fixed resistance is applied to the flywheel
  4. Athlete continues to pedal ‘all out’ for 30 secs
  5. An electrical/mechanical counter continuously records flywheel revolutions in 5 sec intervals

Q

Protocol of RAST (fitness test for dynamic strength)

Study These Flashcards
A
  1. Athlete weighed prior to test
  2. 10-15 min warm up, 5 min recovery
  3. Completes 6x35metre run at maximum pace (10 secs allowed between each sprint for turn around)
  4. Assistant records time taken for each 35m sprint to nearest 100th of a second
  5. For the 6 times calculate the power for each and then determine max power (highest value) and min power (lowest value)
  6. Work out average and fatigue index
    Average= (sum of all 6) / 6
    Fatigue index= (max-min) / (sum of all 6)
20
Q

Advantages of RAST (fitness test for dynamic strength)

Study These Flashcards
A

Suitable for footballers, ruby players, runners

No specialist equipment needed/minimal equipment needed

21
Q

Disadvantages of RAST (fitness test for dynamic strength)

Study These Flashcards
A

May not be able to stick to the 10 sec turnaround if not fit enough
Assistant is required

22
Q

Definition of endurance strength

Study These Flashcards
A

Ability of a muscle to sustain repeated muscle contractions

23
Q

What is endurance strength closely linked with and why

Study These Flashcards
A

Aerobic capacity, as strength endurance is the ability of the muscles to utilise the oxygen taken and transported to the muscle cells

24
Q

Explain the two types of endurance strength

Study These Flashcards
A

Whole body endurance -using the whole body

Local muscular endurance -certain part of the body

25
What is the fitness test for endurance strength and what does it measure
Abdominal crunch/sit up test | Measures core endurance which is important in all sports
26
Protocol of the abdominal crunch test (fitness test for endurance strength)
Sit up every two seconds Back must be flat on the floor Hands on head Do till cannot do anymore
27
Advantages of the abdominal crunch test (fitness test for endurance strength)
Cheap-no equipment Several people can do it at once Can do it by yourself
28
Disadvantages of the abdominal crunch test (fitness test for endurance strength)
Unreliability - counting, not strictly following protocol
29
Sporting example of endurance strength
Canoeist utilise strength in arms (local muscular endurance)
30
Sporting example of dynamic strength
100m butterfly -uses lactic acid system
31
What are the 5 factors that affect strength
``` Gender Muscle composition Age Physical inactivity Types of training ```
32
How does gender affect strength
Mean are generally stronger than females - size of men's muscles are greater - males have more testosterone than females so are able to produce more powerful contracting
33
How does muscle composition affect strength
Higher percent of 2B muscle fibres = stronger Increase in muscle size = stronger Replicate these two points through training
34
How does age affect strength
Women reach peak strength earlier (16-25 to 18-30) -females hit puberty first (maturation rate it quicker) -highest levels of testosterone for both is between 25-30 Strength decreases after 30 years old -less testosterone -muscles get weak (muscle atrophy) -less efficient neuromuscular relationship
35
How does physical inactivity affect strength
Atrophy starts to occur 48 hours post activity
36
What are the types of training that increase strength
Weight training (resistance machines and free weights) Circuits Interval Plyometrics
37
Adaptations due to strength training
Development of type 2B muscle fibres Muscular hypertrophy More tolerant to lactic acid
38
Definition of maximum strength
Maximum force of the neuromuscular system that can be generated in a single contraction/1RM
39
What are the four training methods to improve strength
Interval/circuit Plyometrics Free weight training Weight resistant training
40
Explain interval/circuit training to improve strength
Fixed - certain reps and sets Individual (as many as you can do in a set period of time) Short period from 30secs-3mins Aerobic and anaerobic performers Aerobic 1:1 (3min work:3min rest) Anaerobic 1:4/1:6 (10sec work:60sec rest) 6 reps, 4-6 sets High intensity (80-95%) Circuit exercises: plank, squats, sit/press ups, veritable jump
41
Advantages/disadvantages of interval/circuit training
Interval: +very adaptable for an/aerobic performers -must make sure ratio is correct or not benefit Circuit: +large numbers, small space, little equipment -generalising -not for elite performer
42
Explain plyometric training to improve strength
``` High intensity (PC systems) - 80-95% Box jump, high/triple/long jump 1. Eccentric contraction (lengthen) 2. Short holding phase 3. Concentric contraction (shorten) -more powerful due to hold ```
43
Advantages/disadvantages of plyometric training
+explosive activities/replicates movements +autonomous/elite performers -high risk for cognitive learners -not much muscle strength -high risk of DOMS causes by new activity
44
Explain free weight training to improve strength
``` Experience/advanced performers Includes sets/reps Can replicate similar sporting actions Need a spotter for safety reasons Can alter sets, reps and weights ```
45
Advantages/disadvantages of free weight training
+sporting actions link +adaptable -safety (if not spotter) -poor technique and posture is affect =injury
46
Explain weight resistant training to improve strength
``` For beginners (cognitive) Sets and reps (5 reps, 4-6 sets) 1:4 work:rest ratio Easier to use than free weights More general Change sets, weights and reps 80-95%exercise intensity ```
47
Advantages/disadvantages of weight resistant training
+all levels of performers +adaptable +safety is very high -cannot do sporting action so not precise
