Intensity zones on classical distances in amateur radio direction finding for 13-14 year-olds

| 总结: | The study found that the aerobic-/anaerobic-work-specific heart rates in the 13-14 year-old competitors in amateur radio direction finding (ARDF) are higher than in their adult peers. Sampled for the study purposes were 8 RLS competitors aged 13.5±0.5 years on average, with the RL sport records averaging 3.3±0.5 years and with the following formal sport qualifications: Class I (n=1), Class II (n=4), Class III (n=3) including three prospects for the Russian national team. Based on the HR variation and blood lactate variation test data on the classical ARDF distance, we found the following: the run intensity of the sample is widely variable in the aerobic/aerobic-anaerobic energy supply modes; blood lactate level at the moment of direction finding is somewhat above the anaerobic threshold albeit the lactate level is assumed to fall due to the run intensity drops (as provided by the HR data) to the levels that make it possible for the young athletes to effectively compete |
