Origin of plyometrics |
- Early publications in Russia (later 60s/eearly 70s) |
|
Plyometrics definition |
- Latin origin - Plio (more) + metric (measures) = plyometrics (measurable increases) |
|
Plyometrics and muscle activity |
- max amount of tension in a muscle in the shortest amount of time - muscles possess ability to impart dynamic activity to the body (store and release energy to allow for powerful movement) |
|
Stretch shortening cycle (SSC) |
- employs both the energy storage of the series elastic component (mechanical) and stimulation of the stretch reflex (neurophysiological) to facilitate maximal increase in muscle recruitment over a minimal amount of time. |
|
3 phases of stretch shortening cycle |
- Eccentric - Amorization |
|
__________ is vital to muscle recruitment and activity resulting from the SSC |
A fast rate of musculotendinous |
|
|
A - Eccentric |
|
Mechanical Model |
- Elastic energy in musculotendinous units are increased with a rapid stretch (eccentric muscle action) and then briefly stored |
|
What happens if a concentric muscle action does not immediately follow the eccentric muscle action? |
- The stored energy is released as heat |
|
Series elastic component (SEC) |
- When stretched, stores elastic energy that increases the force produced |
|
Contractile component (CC) [i.e., actin, myosin, and crossbridges] |
- The primary source of muscle force during concentric muscle action |
|
Parallel elastic component (PEC) [i.e., epimysium, perimysium, endomysium, and sarcolemma) |
- Exerts a passive force with unstimulated muscle stretch |

Determine max jump height |
1. The athlete is measured as accurately as possible for astanding jump-and-reach 2.

If the athlete successfully executes this task, he or shemay move to a higher box. The box height should beincreased in 6-inch increments. Step 2 is repeated untilthe athlete fails to reach the standing jump-and-reachheight. This then becomes the athlete’s maximum heightfor depth jumps. 4.

|
|
Maximal aerobic power |

|
Performance in aerobic endurance events also depends on |
- High lactate threshold - Good exercise economy - High ability to use fat as fuel - High number of type 1 fibres |
|
Lactate threshold |
- Point at which blood lactate concentration begins to increase above resting levels (1.0 mmol) - Better indicator of aerobic endurance power than VO2 max |
|
Max lactate steady state |

|
Training intensity is controlled by |
- Heart rate (% of max) - Velocity (% of velocity at VO2max or peak velocity) - RPE - Blood lactate levels (aerobic and anaerobic thresholds) - Work:rest ratio |
|
HR calculation terms |
- APMHR (age predicted max heart rate) = 220-age - HRR (heart rate reserve) = APMHR - RHR - Ex Int (exercise intensity) = % of VO2 max |
|
HR calculations (Karvonen method) |
THR (target heart rate) = (HRR x Ex Int) + RHR |
|
HR calculations (% of max HR method) |
THR = APMHR x Ex Int |

Types of aerobic endurance training |
|
|
Long, slow distance training |
- Training is longer than race distance at 70% VO2max |
|
Adaptations from long, slow distance training |
- Enhances the body's ability to clear lactate - Chronic use of this training causes type IIx fibres to become type I - Intensity is lower than that of competition (bad if used too much) |
|
Pace / tempo training |
- Intensity at or slightly above that of competition (at lactate threshold) |
|
Steady pace / tempo training |
- 20-30 minutes of continuous training at lactate threshold |
|
Intermittent pace / tempo training |
- Series of shorter intervals with brief recovery periods |
|
Adaptations from pace / tempo training |
- Develop a sense of race pace and enhance the body's ability to sustain exercise at that pace - Improve running economy and increase lactate threshold |
|
Interval training |
- Training near VO2 max for 3-5 minute intervals - Work:rest = 1:1 |
|
Adaptations of interval training |
- Allows athlete to train close to VO2max for a greater amount of time - Increases VO2 max and enhances anaerobic metabolism - Use method sparingly and only for athlete with firm aerobic endurance training base |
|
Repetition training |
- Intensity greater than VO2 max - Work interval lasts 30-90s - Work:rest = 1:5 |
|
Adaptations from repetition training |
- Improve running speed and economy - Increased capacity and tolerance for anaerobic metabolism |
|
Resting heart rate |
- Determined by genetics and fitness level - Indicator of aerobic fitness - Marker of overtraining - Can be elevated due to anxiety, dehydration, high ambient temperature, altitude, sickness or digestion |
|
Aerobic threshold heart rate |
- The HR at which anaerobic metabolism begins to increase - 60-65% of max HR - Blood lactate: 1-2 mmol - RPE: 9-10 |
|
Lactate threshold heart rate |
- The HR at which lactate production exceeds lactate removal - 80-85% of max HR - Blood lactate: 4 mmol - RPE: 14 |
|
Maximum heart rate |
- Primarily determined by genetics, age and gender - Can vary up to 6-8 beats/min due to training - Must be assessed through fitness testing - 220-age (variability of 12+ beats/min_ - MHR's differ based on activity performed (running, cycling, swimming) |

- In young healthy persons HIT is a time efficient strategy to stimulate a physiological response similar to traditional endurance training |
|
Aerobic conditioning for team sports athletics |
- Sport specific conditioning can increase both aerobic fitness and game skills, potentially being the most valuable method of training. - However it is dependent on a minimum skill level required to maintain a sufficient intensity - If intensity cannot be maintained, simplify the task while maintaining the intensity |
|
Rules of design |
- Specificity - Overload - Progression |
|
Specificity |
- Train athlete in a specific manner to produce specific adaptation - SAID principle - Mimic the movement patterns / velocity / intensity of sport |
|
Overload |
- Training stimulus at a greater intensity than the athlete is used to - Increase sessions, exercises or sets - Decrease rest - Stress the body |
|
Progression |
- Training intensity must become progressively greater - Continually promotes long term development - Increase intensity / velocity / load / volume |
|
ATP / PCR |
