Comparison of the acute effects of low vs. high altitude on autonomic nervous system during 3000-m running and recovery in elite youth athletes

Purpose The main aim of the present study was to compare the immediate recovery of RR values of HRV as well as HR subsequent and during 3000-m running in LA and HA in youth elite athletes. Methods Seventeen elite youth mid-distance athletes voluntarily participated in the study (mean ± SD; age 14.9 ± 1.3 years; height 164.1 ± 6.6 cm; weight 53.2 ± 8.6 kg). All athletes performed 2 different sessions (LA and HA) at the same time of day two weeks apart. The interventions were held in the racetrack regions of the Botanical Park (~155-m above sea level, 24°-26°) and Uludag Cobankaya (~1750-m, 16°-18°) in Bursa. Afterward, to determine the HR and the HRV of all athletes, a Polar H7 chest strap with a Polar V800 heart rate monitor was used. Results For HR values in LA, there was no significant correlation between the correlation of during 3000-m run and after 10-min recovery with time, respectively (r2 = .008, r2 = .096). In the HR values in HA, there was no significant correlation between the correlation of during 3000-m run and after 10-min recovery with time, respectively (r2 = .033, r2 = .008). There was no significant correlation between the correlation of during 3000-m run and after 10-min recovery with time, espectively in RR values in LA (r2 = .004, r2 = .087). In RR values in HA, there was no significant relationship between the correlation of during 3000-m run and after 10-min recovery with time, respectively (r2 = .024, r2 = .005). Conclusion For athletes, exercise training for oxygen levels at different altitudes may help to shorten the running time. Future studies should examine the cardiac autonomic long-term responses of elite runners in distance running at different altitudes about running time performance and try to examine and improve recovery processes.
