Blunted neuro-endocrine responses linking depressive symptoms and ECG left ventricular hypertrophy in black Africans: the SABPA study
(Wolters Kluwer, 2014)Objective: Chronic psychosocial stress as experienced in an urban environment plays an important role in the aetiology of depression-related cardiovascular risk. It is uncertain whether acute mental stress responses aggravate ... -
Caffeine improves triathlon performance: a field study in males and females
(Human Kinetics, 2018)The ergogenic effect of caffeine on endurance exercise is commonly accepted. We aimed to elucidate realistically the effect of caffeine on triathlon event performance using a field study design, while allowing investigation ... -
Defensive coping and renovascular disease risk. Adrenal fatigue in a cohort of Africans and Caucasians: the SABPA study
(Elsevier, 2015)Background: Defensive coping is an established cardiovascular risk factor in Africans. Additionally, chronic, excessive or inadequate hypothalamic pituitary adrenal axis (HPAA) stress responses could either increase or ... -
Defensive coping facilitated a smaller cortisol-to-estradiol ratio and a higher hypertension risk: the SABPA study
(Taylor & Francis, 2018)Objectives: Taxing psychosocial stress and defensive coping have been associated with hypoactivity in cortisol, a vasoconstrictive agent. Estradiol has vasodilatory properties with cardio- and neuroprotective effects. It ... -
