Open Access
Online First is a feature that enables the publication of final revised articles online before their inclusion in a printed issue. This accelerates the dissemination of research findings and ensures that your authors' work reaches the audience promptly.
Articles published through Online First are assigned a DOI upon their online posting. They should be cited as follows:
Author(s). Title of the article. Exercise and Quality of Life. Advance online publication. DOI:10.31382/xxxx
After assignment to a final issue, citations can include the volume and page numbers in addition to the DOI.
Once articles are allocated to a specific issue, their hosting transitions from the Online First page to the main journal archive. The DOI ensures persistent accessibility.
Citations to Online First articles are counted toward the journal's Impact Factor if other indexing criteria are met. This promotes earlier engagement with the published work.
Online First articles are considered final but not definitive until assigned to a specific issue. Errors identified in the online version can be corrected before the final issue publication.

A comparison of heart rates between simulated and real altitude
The aim of the presents study is to make a comparison between heart rates measured at real altitude and at the simulated altitude (in hypoxic chamber), before and after the process of acclimatization. Six students (two women and four men) of Faculty of sport in Ljubljana participated in the study. They undergone eighteen day long acclimatization process on 2100 - 5642 m. Heart rates were measured in rest and during the step test before and after the acclimatization, at two locations: high altitude simulation chamber in Ljubljana and real altitude in Elbrus, Kavkaz, both at 2100 m. The results showed that heart rates were not significantly different between real altitude and simulated altitude. Acclimatization process caused a decrease of heart rates in both cases. From that we can conclude that it would be possible to train in hypoxic chamber and therefore shorten the acclimatization time in real very high mountains. Heart rate could be used as an objective parameter of the quality of the acclimatization. This should be proven in the future by research on bigger sample.
