Cerebral, cardiac and skeletal muscle stress associated with a series of static and dynamic apnoeas

Purpose This study sought to explore, for the first time, the effects of repeated maximal static and dynamic apnoeic attempts on the physiological milieu by assessing cerebral, cardiac and striatal muscle stress‐related biomarkers in a group of elite breath‐hold divers (EBHD).

Description
Summary:Purpose This study sought to explore, for the first time, the effects of repeated maximal static and dynamic apnoeic attempts on the physiological milieu by assessing cerebral, cardiac and striatal muscle stress‐related biomarkers in a group of elite breath‐hold divers (EBHD). Methods Sixteen healthy males were recruited (EBHD = 8; controls = 8). On two separate occasions, EBHD performed two sets of five repeated maximal static apnoeas (STA) or five repeated maximal dynamic apnoeas (DYN). Controls performed a static eupnoeic protocol to negate any effects of water immersion and diurnal variation on haematology (CTL). Venous blood samples were drawn at 30, 90, and 180 min after each protocol to determine S100β, neuron‐specific enolase (NSE), myoglobin, and high sensitivity cardiac troponin T (hscTNT) concentrations. Results S100β and myoglobin concentrations were elevated following both apnoeic interventions (p
