Background: The prevalence of allergy in athletes has been increasing, especially, in elite endurance athletes. Allergy influences wellbeing and probably, the athletic performance,
however, its influences on daily training and muscle response remains unknown. The purpose of this study was to compare the training variables and muscle response between elite endurance athletes with
and without allergy.
Methods: Forty male elite runners aged between 20 and 40 years were assessed in this cross sectional study. The performance time required for the athletes’ inclusion were 2h30min in
marathon, 1h10min in half marathon and 33min in 10km. The athletes were submitted to a blood sample to determine imunoglobulina E (IgE) specific and creatine kinase (CK) levels. Athletes levels of
specific IgE ≥ 0.35 kU/l were included in the allergic group (AG). The training routine of athletes was assessed by a specific questionnaire based on the last week of training, with questions about:
Number of sessions (NS), hours of training (HT), training volume in kilometers (TV), rating perception recovery (RPR) and rating perceived exertion (RPE). The training load (TL) was calculated by
multiplying the RPE x TV. Statistical analysis: comparison between groups was performed using the Mann-Whitney test for nonparametric data and t test for parametric data, the significance level was
set at 5%.
Results: Twenty-two athletes were included in the allergic group (AG) and 18 in the non allergic group (NAG). There was no difference between groups for NS; HT; TV; RPR; RPE; TL and
CK. Both allergic and non allergic athletes presented CK within the normal range for elite athletes (AG = 322.2 ± 192; GNA = 373.4 ± 197.8).
Conclusions: It seems that allergy in elite runners does not influence training variables and muscle enzyme response.
