Physiological and selective attention demands during an international rally motor sport event.

Turner AP, Richards H - Biomed Res Int (2015)

Bottom Line: In ambient temperatures of 20.1°C (in-car peak 33.9°C) mean (SD) peak HR and T core were significantly elevated (P < 0.05) during rally compared to reconnaissance (166 (17) versus 111 (16) beats · min(-1) and 38.5 (0.4) versus 37.6 (0.2)°C, resp.).Environmental and physical demands during rally competition produced significant physiological responses.Challenges to thermoregulation, hydration status, and cognitive function need to be addressed to minimise potentially negative effects on performance and safety.

ABSTRACT

Purpose: To monitor physiological and attention responses of drivers and codrivers during a World Rally Championship (WRC) event.

Methods: Observational data were collected from ten male drivers/codrivers on heart rate (HR), core body (T core) and skin temperature (T sk), hydration status (urine osmolality), fluid intake (self-report), and visual and auditory selective attention (performance tests). Measures were taken pre-, mid-, and postcompetition day and also during the precompetition reconnaissance.

Results: In ambient temperatures of 20.1°C (in-car peak 33.9°C) mean (SD) peak HR and T core were significantly elevated (P < 0.05) during rally compared to reconnaissance (166 (17) versus 111 (16) beats · min(-1) and 38.5 (0.4) versus 37.6 (0.2)°C, resp.). Values during competitive stages were substantially higher in drivers. High urine osmolality was indicated in some drivers within competition. Attention was maintained during the event but was significantly lower prerally, though with considerable individual variation.

Conclusions: Environmental and physical demands during rally competition produced significant physiological responses. Challenges to thermoregulation, hydration status, and cognitive function need to be addressed to minimise potentially negative effects on performance and safety.

Mean (SD) values for scores of drivers and codrivers in the map search test of selective attention at the start of the day (pre), during the day (mid) and at the end of one day of the reconnaissance (recce-hashed boxes) and then one day of the rally competition (solid black boxes). *Significantly lower than postreconnaissance (P = 0.007), mid- (P = 0.002) and postrally (P = 0.01); #significantly higher than pre- (P = 0.002) and postreconnaissance (P = 0.01).

Mentions: Attention scores on the map search task (Figure 3) showed a significant main effect of time (P < 0.001, r = 0.85), with lowest attention scores prereconnaissance and prerally although no significant difference between them (P > 0.99). Prerally attention was significantly lower than midrally (P = 0.002), postrally (P = 0.01) and postreconnaissance performance (P = 0.007). The highest attention level was midrally, significantly higher than both reconnaissance day performances (P = 0.002 and 0.01), but not significantly different to postrally (P = 0.401). There was no significant main effect of time on the auditory working memory task (P = 0.719, r = 0.26). This measure showed a tendency towards a ceiling effect.
