Abstract
In the water-polo game, acyclic movements are predominant, but during a match, the swimming technique, the covered distances and the swimming intensity are different, which indicates that a water-polo player must train with all three types of effort (aerobic, anaerobic lactacid and anaerobic alactacid ones).
Hypothesis of the research: knowing in real time the heart rate (HR) values during the training sessions allows the water-polo coaches to efficiently manage the effort, in order to reach the objectives established.
To validate this hypothesis, the following methods were used: test method, graphical method, statistical-mathematical method, etc. The test was administered to 4 athletes and consisted of freestyle swimming 3x (4x100m), with a 10-second break between repetitions and 5 minutes between series. Heart rate is monitored by means of the HOSAND GT.a telemetry system, which allows visualization of the group or individual sports performance and analysis of the HR curve and of the effort intensity within a training session. Hosand GT.a comprises: the TX200 transmitter wore by the athlete, together with a standard belt which measures the heart rate, the RX200 receiver, the SX200 box for synchronization and the SW200 software.
Athlete 1 starts with a HR of 94 beats/min, at the end of the warm-up the HR is 179 beats/min, after the first series the HR reaches 195 beats/min, after the second series the HR reaches 197 beats/min and after the third series it attains 196 beats/min, which corresponds to a work intensity close to 90%. HOSAND GT.a offers a personalized training and, at the same time, a monitoring in real time of the training, the heart rate contributing professionally to the improvement of the coached athlete's or team's performance.
Analyzing the data, the hypothesis has been validated and the research meets the interest of the Romanian Water-Polo Federation. |
