  1. Heart-rate Recordings – Aerobic loading

  2. Heart-rate and Exercise Intensity How can work load during very short periods of high intensity exercise interspersed with longer periods of low intensity exercise or standing stillbe monitored?

  3. Polar Team System • Interface and Re charger Unit • Slots for 10 transmitters Quick info display for each transmitter • Player number • New exercises • Accumulator state • Free memory • Pre-programmed exercise start • Time and date

  4. Team Transmitter • Polar Coded transmitter with accumulator and memory • 5s recording rate  11h 20min • No necessity for external HR monitor • Automatic start & stopof HR recording • Communicates tocomputer via IRU

  5. Key Benefits • Monitor exercises • - Feedback direct from heart-rate (HR) • Control training intensity • - Set the right intensity for right session • Make individual endurance training plan • Optimize individual player’s condition • Interference-free HR recording

  6. Resting, Maximal & Target Heart-rate • Resting Heart Rate • Norm: 40-60 beats per minute • influenced by training status • Maximal Heart Rate • Norm: (for active, adult players ) • between 160-220+ • decreases with increasing age • no reflection of training status

  7. Heart-rate during a game for one player Peak heart-rate: 184 b.p.m. First-half Second-half

  8. Heart-rate and Exercise Intensity An increase in exercise intensity is reflected by a linear increase in heart rate and oxygen uptake

  9. Heart-rate and Exercise Intensity An increase in exercise intensity is reflected by a linear increase in heart rate and oxygen uptake

  10. Estimated oxygen uptake during a match First-half 3.8 lO2/min ~75%VO2max Second-half 3.5 lO2/min ~69%VO2max

  11. Mean heart-rate during a soccer match - 5 min intervals Mean HR 174 b.p.m. Mean HR 171 b.p.m.

  12. Heart-rate distribution during a soccer game HR max 187 beats/min

  13. Why measure heart-rate ? • To improve football specific endurancecapacity • To make the training as football specific as possible • To reduce the time spent on training without the ball

  14. Why measure heart-rate ? • to educate coaches and players • to monitor exercise intensity during drills with the ball • to control exercise intensity during drills with the ball • to monitor fitness levels • to minimise risk of “over-training” • to monitor exercise intensity during rehabilitation

  15. Training drills with the ball ensures that... • specific muscle groups used in football are trained • players develop technical and tactical skills under conditions similar to those encountered in a match (stress) • there is greater motivation for players compared to running without the ball

  16. Why Heart-rate Monitors? Specific

  17. Principles of Aerobic Training

  18. Aerobic High-intensity Training Examples of Exercise to Rest ratio and Heart-rate intensity %

  19. Heart-rate during an Aerobic high-intensity drill

  20. Resting, Maximal & Target Heart-rate Target Heart-rate

  21. Why Heart-rate Monitors? Specific

  22. Treadmill Running Heart-rate (HR) • WorkRestRep • 4 min : 1 min x 3 – HR 90% of max • 2 min : 1 min x 5 – HR 90% of max • 1 min : 1 min x 7 – HR 90% of max • 30 sec : 30 sec x 9 – HR 90% of max • Start with 5 mins warm-up followed by 1 min of rest before start • Use the first interval to find the right intensity (running speed based on heart rate)

  23. Determining MaximalHeart-rate • Relative aerobic loading

  24. Resting, Maximal & Target Heart-rate Measuring Maximal Heart Rate

  25. Yo-Yo Intermittent Recovery Test 20 meters 5 meters

  26. Heart-rate during Yo-Yo Test
