Physiological Stress in Safer Cycling in Older Age (SiFAr-Stress): A Randomized Controlled Trial

One possibility for maintaining mobility in older age is cycling. We investigated the impact of the multicomponent "<i>Safer Cycling in Older Age</i>" (SiFAr) intervention on psychological and physiological stress. Participants were 98 community-dwelling older adults (73.4 ± 5.4 years). Bedtime cortisol, hair cortisol concentrations, and C-reactive protein were measured before and after the 8-week SiFAr intervention and at follow-up. Additionally, acute stress responses were assessed during the second and seventh training sessions using salivary alpha-amylase and cortisol assessments. We found a decrease in acute perceived stress, anxiety, fear of falling, and uncertainty during the cycling trainings. Moreover, long-term perceived stress significantly decreased. No significant changes were found for any of the physiological stress measures. We conclude that cycling had a positive impact on perceived stress and wellbeing. Further research with more intense trainings is needed to fully understand the associations between cycling in older age and physiological stress.
