Effect of Motorcycling on Salivary Noise-Induced Cortisol among Young Motorcyclists

Abstract

Saliva cortisol response was investigated from the motorcycling exposure for approximately 50 minutes between low and high noisesensitive (Weinstein Noise Sensitivity Scale) young riders (19-25 years). The results showed significant difference (p < 0.05) in salivary cortisol concentrations in High-Noise Sensitive group (n = 27). Significant gender differences were found (p < 0.05) among the Low-Noise sensitive group (n = 30), after ride. Cross-analysis between groups was significant (p < 0.05) for before ride cortisol levels of Low-Noise sensitive group. This study suggests that subjective noise sensitivity plays a vital role in increased cortisol level among noise sensitive riders.

A Controlled Study on Young Motorcyclist’s Cognitive Function

“…In contrast, it was indicated by (Helton, Matthews, & Warm, 2009) that vigilant performance tends to be better under noise conditions and it also increases self-reported task-engagement. A recent study reported that young motorcyclist's (19-25 years) demonstrated increased physiological stress reaction due to motorcycling both in field and controlled experimental studies (Anila Ali, Dom, Hussain, & Abdullah, 2017) (Anila Ali, Hussain, Abdullah, & Dom, 2018) and weak audiometry profile (Anila Ali, Dom, Hussain, Karuppannan, & Abdullah, 2018). Previously, studies relating to physiological and psychological profile of young motorcyclists are scarce, while no studies have quantified any relation between motorcycling noise and cognitive function.…”
