Salivary endocrine response following a maximal incremental cycling protocol with local vibration
Jemni et al.
The finding, in our words
Vibration during maximal cycling increased salivary cortisol by 83% compared with no vibration, while testosterone did not differ, reducing the testosterone/cortisol ratio. This demonstrates that saliva can detect exercise modality effects on stress hormones, which could inform remote monitoring of training load or rehabilitation if self-collection methods were validated.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
This study used home self-collected saliva samples to successfully monitor cytokines and cortisol in mothers and infants, finding that a community singing intervention significantly reduced salivary interleukin-6 levels in mothers with postnatal depression.
Cortisol dynamic range measured from participant-led saliva collection was feasible and associated with higher perceived stress and anxiety in African American women, suggesting saliva self-collection can serve as a decentralised biomarker of chronic stress.
In women with endometriosis, longer individual exercise sessions were associated with lower levels of salivary c-reactive protein and estradiol, as well as reduced pain and fat mass. The results demonstrate the utility of timed, at-home saliva self-collection for assessing systemic biomarkers in reproductive health research.
Using Saliva Children's Swabs to collect salivary alpha-amylase and cortisol was feasible in elderly nursing home residents with dementia, though active patient engagement remained necessary. However, an individualised music listening intervention showed no significant effect on these salivary stress markers.
In 60 healthy young adults who self-collected saliva, habitual coffee consumption at low, moderate or high intake did not significantly alter morning or evening levels of salivary cortisol or alpha amylase under non-stressful conditions. This suggests that for decentralised diagnostics, coffee drinking is unlikely to confound salivary hormone results, supporting the validity of self-collection for cortisol and stress biomarker monitoring.
