Optimization of the Exercise Intensity Using Real-Time Heart Rate Telemetry System (H. Hasegawa) 2nd Congress of The Japanese Society of Science and Football - Optimization of the Exercise Intensity Using Real-Time Heart Rate Telemetry System during a Technical and Tactical Training in Football
2nd Congress of The Japanese Society of Science and Football March 5th-6th, 2005 Tokyo Institute of Technology, Tokyo Japan
Background 1Specific Endurance Training in Football - Running training without ball
- Rationality of a training with balls in a game style, (Bangsbo 1994a,bBalsom 1997)
- It is premised on that the every athletes participating the training game in their optimum range of the exercise intensity to attain the training goal of the football specific endurance.
Background 2Various factors for affecting excise intensity in a small sided game - Size of the fields
- Number of the players
- Ratio and duration of the play and the rest period
- Regulations(number of ball contact, how to get a goal)
- Skill and tactical understanding of the players
- Positions of the players
- Readiness
- Motivation
Purpose
To verify a possibilities and advantages of the utilization of a new coaching technology that allows to control the exercise intensity of the each athletes on the spot during a small sided game by means of the real time heart rate telemetry for a group of athletes.
Methods(1):Subjects and Acquisition of HR data
Six Collegiate Football Players:
21.0±1.3 years oldA171.2±5.4cmA64.2±7.2kg Acquisition of HR Data:Polar Wear Link 31C Monitoring HR:HOSAND ® TM200(Hosand Technology, Verbania, Italy) HOSAND® TM200 Display of group heart rate
Methods(2): Setting of exercise intensity
Maximum Heart Rate(HRmax)
YO-YO Intermittent Recovery Test (YYIRT). Peak heart rates at the all-out point of the YYIRT were taken as the Maximum heart rates (HRmax) (Krusrup et al. 2003). Exercise Intensity(%HRmax) Setting a percentage of a maximum heart rates by mean of Indicate on the display of individual heart rate of HOSAND ® TM200 software 65-75%, 75-80%,80-85%, 85-92%, 92-100% Setting a relative exercise intensity based on individual HRmax from YYIRT and Percentage of the HRmax Display of individual heart rate
Mehods(3) Small sided game training - 3 vs.1 Ball Possession
- Playing area:10m×10m
- Work :40sec, Rest:20sec
- Restricted under two touch of the ball
- 3 sets
- 6 vs.6 Man to Man Ball Possession
- Playing area :30m x 40m
- Without restriction for the number of ball touch
- Work: 120 sec, rest 60 sec.
- 4 sets
- 6 vs.6 GameiRegular Goal with GK)
- Playing area:Half sized field with With regular goal
- Work: 5min, Rest: 2min.
- 3 sets
Conclusion
Heart rate monitory by HOSAND TM200® could cover all of a football field multiple players simultaneously in optimal condition.
Responding to the coaching requiring a optimum play during a small-sided game, %HRmax increase up to 90% in average, 95% at maximum. Controlling the exercise intensity during the small-sided games using real-time heart rate telemetry system used in this study appear to be effective to improve football specific endurance, and technical and tactical skill at a time.
