The study was designed to rate the heart rate variability in the ethnic sledge over-jumping sport with 12 athletes of different skill levels aged 17 years on average being subject to the study. The heart rate variations were profiled using a Polar FT80 pulsometer in the tests where each athlete was required to jump over sledges to the maximum in only one attempt. The subjects were given 20 min to warm up followed by the sledge jumping exercise performed as required by the rules of the competitions. The heart rates were fixed prior to the start and after every series of 20 sledge jumps.
The study data and analyses showed the highly-skilled athletes’ heart rates being on average lower than that of the lower-skilled athletes, the situation being quite typical for many sports where the less experienced athletes tend to act at higher heart rates. It should be noted, however, that every athlete showed good health progress in the tests with the heart rates following the tests varying within 50 to 51.2 beats per min. This effect may be due to the tests being designed to closely simulate real competitions so as to attain the maximum possible effect. It was also found that the HR smoothly increased in the test performance process, with the HR varying within 170-190 beats per min being found optimal for the sledge over-jumping success. The skill-specific HR control data in the sledge over-jumping process may be beneficial for the cardiovascular system response profiling and prudent training process design purposes in the ethnic sledge over-jumping sport.
