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.

The effects of 8 wk intensive judo training on the humoral immune system in judo fighters
The influence of intensive Judo training on serum immunoglobulins IgG, IgM, and IgA was studied in 24 Judo fighters. Subjects were assigned to an exercise training group (EXE; n=12) and non-exercise control group (Con; n=12). Subjects in EXE group participated in exercise sessions 4 days a week for 8 wk. Serum samples were collected before, immediately and 1wk after study period. The IgG levels were significantly increased immediately after exercise training (p=0.001) in EXE compared to Con. However, IgM and IgA concentrations showed significant decrease immediately after exercise in EXE (p=0.001). The concentrations of all immunoglobulins had returned to baseline by 1wk of recovery. In conclusion the increased IgG levels are possibly due to isotype switching or a secondary antibody responses that could be considered as enhancement in immune system function. However, chronic suppression of immuniglobulins IgM and IgA may be mediated by hormonal changes associated with exhausting exercise.
