“…Across the duration of a sport event, athletes must endure compounding psychophysiological demands which can influence perceptual and physiological responses that may negatively impact upon performance. 1,2 The cumulative effects of exertion and physiological responses (e.g., blood lactate), derived from the management of physical load athletes contend with during performance, can manifest implications for perceptual-cognitive components of sport performance (e.g., aiming in biathlon). 3,4 However, limited research has investigated how physiological responses, affective states, and exertion may influence cognitive and physical sport performance both independently and simultaneously.…”
