Mental fatigue, defined as a psychobiological state that can be caused by engaging in demanding cognitive activity for a prolonged period, is characterised by subjective feelings of tiredness and lack of energy (Marcora et al., 2009). It has been associated with reduced task speed and accuracy when performing subsequent tasks (e.g., Boksem et al., 2005). It is also well documented that a mentally-fatiguing cognitive task can impair subsequent exercise performance. The mechanism underlying these effects and their boundary conditions have yet to be established. Accordingly, there remain gaps in our understanding of the mental fatigue-performance relationship. First, studies have yet to establish the role of cognitive task scheduling on subsequent exercise performance. Second, the importance of perceptual factors (see Jameson & Ring, 2000) in this relationship have not been fully explored. Accordingly, to address these gaps in our understanding, the current study will (a) examine the effects of cognitive task scheduling on mental fatigue and cycling exercise performance, and (b) explore the importance of perceptions of internal states (e.g., breathing, heart beating, muscle tension) on the effects of mentally-fatiguing cognitive tasks on cycling.

精神疲劳被定义为由于长时间从事高要求的认知活动而引起的一种心理生物学状态，其特征是主观感觉疲劳和缺乏能量（Marcora等人，2009）。它与执行后续任务时任务速度和准确性的降低有关（例如，Boksem等人，2005）。也有充分的证据表明，精神疲劳的认知任务会损害随后的运动表现。这些效应的机制及其边界条件尚未确定。因此，我们对心理疲劳与表现关系的理解仍存在空白。首先，研究尚未确定认知任务调度对后续运动表现的作用。其次，感知因素在这种关系中的重要性（见Jameson & Ring， 2000）尚未得到充分探讨。因此，为了解决我们理解中的这些空白，本研究将(a)检查认知任务调度对精神疲劳和自行车运动表现的影响，(b)探索内部状态感知（如呼吸、心跳、肌肉紧张）对精神疲劳认知任务对自行车运动的影响的重要性。
