Abstract

This study aimed to investigate whether the influence of CYP1A2 genotype in the blood pressure (BP) response to caffeine ingestion was affected by physical activity status and habitual caffeine consumption. Thirty-seven participants (19-50 years old) took place in the study and were categorized according to i) genotype: CYP1A2 (AA) "fast metabolizer", and CYP1A2 (AC) "slow metabolizer"; ii) physical activity level: sedentary (S) and physically active (A); and iii) caffeine consumption level: non-habitual caffeine consumer (NC) and habitual heavy caffeine consumer (C). All groups had BP assessed before (basal) and 1 hourh after (post) caffeine ingestion (6 mg·kg-1). It was observed that AC genotype individuals had increased basal-DBP and post-caffeine SBP when compared to AA individuals. Additionally, acute caffeine ingestion increased SBP only in the AC group. It was also found that physical activity only modulated the BP responses to acute caffeine ingestion in AC individuals. Furthermore, the results indicated that the habitual heavy caffeine consumers AC individuals had increased basal-DBP when compared to the AA ones. Our results suggest that the influence of CYP1A2 genotype in the basal and post-caffeine BP response to caffeine ingestion is modified by physical activity status and caffeine consumption level.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
