Q

when developing a warm up plan what’s important?

A

Key point: Develop simple to complex activities within each pattern, supplementing with ‘bending’ and ‘rotating’ to activate and challenge mobility of the athlete.

Q

3 things to consider when making an exercise plan?

A
  1. Identify an athlete’s movement deficiencies or muscle activation patterns and select activities that address the deficiencies or challenges.
  2. identify the key movement patterns the athlete will need to perform (as well as the range of motion required) in the upcoming session.
  3. identify the key movement patterns the athlete will need for long-term development.

1837 handball players (879 control vs. 958
intervention, male and female)

X 2 increased incidence of knee and ankle
injuries (Olsen et al., 2005)

Pope et al. (2000)
1279 male army recruits (656 control vs. 623
intervention)

Q

Muscle terminology:

A

Epimysium: surrounds entire muscle

Endomysium: surrounds individual muscle fibers

Perimysium: surrounds bundles of muscle fibers

Sarcolemma: Muscle cell membrane

  • Fascicle = (bundle of muscle fibers)
  • Muscle fiber = (muscle cell)
  • Myofibrils = (make up a fiber)
  • Sarcoplasm = (Cytoplasm)
  • Sarcoplasmic Retic = (Endoplasmic Retic.)
17
Q

simple explanation of muscle contractions:

A

brain receives AP from receptors,

sends AP via sensory nerves such as spindle’s (Length), Golgi (tension), Free nerve ending (e.g. pain, etc.) to the muscles

motor nerves then cause those movements to occur from AP from spinal cord via AP from brain

18
Q

in-depth explanation of muscle contractions:

A
  1. an AP arrives at neuromuscular junction
  2. Acetyl Choline is released, binds to receptors, and opens sodium ion channels, leading to AP in sarcolemma
  3. AP travels along the T-tubules
  4. Calcium combines with Troponin, ADP and PI, thick and thin filament interaction leads to muscle contractions
  5. muscles shorten and produces tension
19
Q

Muscle Temperature on performance?

A

4 subjects

20-s max sprint isokinetic cycling @95
rev.min-1 under 4 conditions -

Rest at room temperature (21-22°C),
and following 45 min lower body immersion at 44, 18 and 12°C

Heat immersion increased muscle temperature by 2.7°C, associated with
increases of ~11% in max peak force and power.

Max peak power showed an average of +4% per °C in muscle temperature compared with resting condition.

20
Q

Effect of Muscle Temperature Injury Risk:

A

Warmer muscles….

Greater stretch at
submaximal loads

Greater deformation prior
to failure

21
Q

what happens to Force-Velocity as body temperature increases?

A

The speed of nerve and muscle functions increases (increases contraction
velocity)

The force velocity curve shifts to right:

  • Increased maximum isometric force
  • Higher maximum velocity at any resistance
  • Fewer motor units are needed to sustain a given force
22
Q

Muscle Temperature and performance?

A

Isokinetic cycling @ 54, 95 and 140 rev.min-1

54 rev.min-1  in Peak Power ~2% per °C

140 rev.min-1  in Peak Power ~10% per °C

Greatest benefits of increasing muscle temperature observed at higher velocities (e.g. high force-high velocity = Explosive Strength)

23
Q

what are the 3 stretching types?

A

Ballistic (BS) – rapid jerking-like movements

Static (SS) – Slow, still, larger ROM (10-12 s)

Dynamic (DS)– Slower, functional movement
(allow specificity!)

24
Q

Stretching and performance?

A

Static stretching results in a
decreased:

  • Strength
  • Power
  • Explosive performance

(throwing, jumping etc.)

WHY? No temp change and
inhibition

25
Q

Stretching inhibition?

A

• Range of motion and injury risk reduction after SS

• Other forms of stretching (BS) don’t tend to match
SS, as above, but can still lead to inhibition

• Proceed with a dynamic warm-up and none of this
could matter

26
Q

what energy systems last the longest (shortest first)

A
  1. Stored ATP (2 secs)
  2. Phosphagen (10 secs)
  3. Glycolysis (2 mins)
  4. Aerobic (2 hours)
27
Q

what do enzymes do?

A

reduce energy of and facilitate reactions

28
Q

ATP– ‘a high-energy phosphate’

what is the basis of energy transfer in the body?

A
  • Recycling of ATP is the basis of energy transfer in the body
  • ATP can ‘donate’ phosphates to drive muscular contraction
    (among other processes)
29
Q

Phosphocreatine system?

A
  • The body does not store enough ATP for exercise
  • The ATP-PC system replenishes ATP rapidly!

ATP and H20-ADP, energy, PI
phosphocreatine is broken down by creatine kinase to form creatine, energy and PI
Energy + PI + ADP= ATP and creatine and energy.

• Creatine kinase reaction to maintain the concentration of ATP

30
Q

Increased non-oxidative metabolism: During exercise increases in muscle
temperature does what?

A

Increase muscle glycogenolysis, glycolysis and high-energy phosphate (ATP and phosphocreatine) degradation during exercise.

31
Q

why watch out for warm-up intensity?

A

Muscle temperature:

3-5 min moderate intensity rapidly increases muscle temperature (~2°C), reaching equilibrium after ~10-20 min.

Workloads above ~60% VO2max shown to decrease PCR and impair short term performance.

32
Q

Exercise Priming (non-temp)

A

Elevation of Baseline Oxygen Consumption

By elevating baseline VO2
through warm-up, less of
the initial work will be completed anaerobically

This should increase time to exhaustion and improve
performance in more prolonged tasks that require a significant anaerobic contribution.

Elevated Baseline O2 on performance
• Short Term ✖
• Intermediate ✓
• Long Term ✓

33
Q

Improved oxygen kinetics

A

2 x 6 min bouts of ‘heavy-domain’ exercise with 20 min passive recovery

Non-temp. related

Possible uses in less complex, closed loop tasks like cycling, running extended mid-long distances

34
Q

summary: muscle temperature

A

3-5 min moderate intensity rapidly increases muscle temperature (~2°C), reaching equilibrium after ~10-20 min. This can:

Enhance power output, particularly at higher velocities

Increase compliance of muscle-tendon junctions

Enhance neural activation patterns

Enhance anaerobic energy supply

35
Q

summary: Stretching

A

Static should < 60 s to ensure no performance decrement but, generally, dynamic stretching is preferable as part of RAMP

36
Q

summary: Exercise Priming

A

Exercise Priming

Not heat related per se

Not intense enough will not speed VO2 kinetics (should be ‘heavy’)

Too intense - decrease high energy phosphate stores, glycogen stores and accumulation of metabolic products (no use later in race). Breaks ↑ and intensity ↓
