Q

Training goals for sprinting

A
  • minimize braking forces at ground contact by maximizing backward velocity of leg and foot at touchdown and planting foot at center of gravity
  • emphasize brief ground support times as a means of achieving rapid stride rate
  • emphasize functional training of hamstrings

Q

Backpedaling technique

A
  • short stride length,
  • greater stride frequency,
  • longer support time,
  • later application of peak GRF,
  • greater hip angular velocity,
  • smaller ROM at hip, knee, and ankle

Q

Sprint assistance

A

Overspeed effect i.e. gravity assisted running, high-speed towing (stretch cord)
- improve stride rate, reduce time/energy needed to accelerate

19
Q

How can you progressively develop and evaluate and athletes braking mechanics?

A
  1. Athlete runs 1/2 (2nd gear) speed and stops in 3 steps
  2. Athlete runs 3/4 (3rd gear) speed and stops in 5 steps
  3. Athletes runs full (4th gear) speed and stops in 7 steps
20
Q

What is the primary method for developing speed and agility?

A

Executing sound movement technique

21
Q

What are the two secondary methods for developing speed and agility?

A

speed resistance and speed assistance

22
Q

What are the 3 tertiary methods for developing speed and agility?

A

Mobility, strength, and speed endurance

23
Q

What is the purpose of speed endurance training?

A

enhance fatigue resistance and tolerance

24
Q

What 3 ways does sprint training effect muscle physiology?

A

hypertrophy (esp. in fast twitch fibers), increased development of sarcoplasmic reticulum, and shifts of both type 1 and 2x fibers to type 2a.

25
What are the 3 methods for speed-endurance development?
- competitive trial method - distance - duration method - interval
26
What are the 3 sub categories of the competitive - trial method? What are the intensity and duration?
Supramaximal - I: greater than competition D: less than competition Maximal - I: equal or less than competition D: equal to competition Submaximal training - I: less than competition D: greater than competition
27
What are the 3 subcategories of of the distance - duration method?
Continuous training - 70-95% competitive power Variable training - structured changes in FTT Fartlek training - unstructured changes in FITT
28
What are the two subcategories of interval method?
Extensive training and Intensive training I: low to medium (60-80%) T: short-medium Volume: large Rest: short relief intervals between reps ( <1/3 time for full recovery) until HR is at 125-130 BPM for advanced athletes (about 45-90 sec) and 110-120 BPM for beginner (about 60-120 sec)
29
What is the Intensity, Time, volume, and rest period between reps for extensive interval training?
I: low to medium (60-80%) T: short-medium Volume: large Rest: short relief intervals between reps ( <1/3 time for full recovery) until HR is at 125-130 BPM for advanced athletes (about 45-90 sec) and 110-120 BPM for beginner (about 60-120 sec)
30
What is the Intensity, Time, volume, and rest period between reps for intensive interval training?
I: high (80-90%) T: short Volume: small Rest: longer than extensive but incomplete, allowing HR to recover to 110-120 bpm 90 to 180 sec for advanced athlete and 120-240 sec for beginner
31
What is the Intensity, Time, volume, and rest period between reps for repetition training?
I: very high (90-100%) T: very short - medium Volume: very small Rest: near complete rest interval and allowing HR to recover to <100 BPM (about 3-5 min)
32
How long of a rest period should be given during speed and agility sessions? Should rest periods be given frequently?
2-3 min. YES
33
Training activities aimed at improving SSC should include?
1. skillfull multi-joint movements that transmit forces through the kinetic chain (plyo) 2. should be separated by frequent rest periods.
34
Define: complex training | What is the advantage of complex training?
1. Alternating SSC tasks (plyo) with heavy resistance exercises within the same session 2. enhances working effect of SSC
35
Which is more important in quick timing tasks (ex. hitting a baseball or saving a PK) reaction time or reactive ability?
Reaction time
36
Define: reactive ability
a trainable characteristic of explosive strength
37
Why is explosive strength training important for long distance aerobic events?
increases stride length, frequency, and efficiency.
38
Running speed is the interaction between ______ ____and _____ _____
stride frequency and stride length.
39
Coordinative abilities are most trainable in adolescents, pre-adolescents, or adults?
pre-adolescent
40
During sprint assistance training the amount of assistance given should be less than or equal to ____ % of the athletes max velocity
10
41
What is the main method used for developing agility?
repetition
42
In terms of short-term development of speed and agility, what are the two most important factors to consider? Which energy system should be primarily targeted?
1. fatigue management and task specificity | 2. phosphagen
43
In terms of development of speed-endurance training, what training method is useful for training athletes for intensive sports?
distance-duration
