The morning alertness factor reflects degree of alertness, tiredness and recovery after waking up from night's sleep.
Attention consists of several components, including alertness, which is the ability to enter an alert state and immediately focus on important aspects of a situation, and vigilance (or sustained attention), which is the ability to maintain the alert state for a period of time (Nigg and Nikolas 2008).
The component scales for alertness were drowsy/alert, strong/feeble, coordinated/clumsy, attentive/dreamy, lethargic/energetic, muzzy/clear headed, incompetent/proficient, and mentally slow/quick witted.
"In terms of physiology and body alertness, there are so many components that go into playing golf," said Shawn Youngstedt, an associate professor in the department of exercise science at the University of South Carolina.
Attention was investigated through its components: distractibility (item 12), alertness (item13), selective attention (item14), divided attention (item15) and sustained attention (item16).
Previous studies have found that restricted sleep, in the absence of physical exertion, compromises many components of cognitive processing, alertness, and performance [ 15– 22].
Subscale I, information processing (score range 0 – 14 points), evaluates components of cognitive status: attention and alertness, verbal and motor response, and memory and orientation.
Attention revolves around alertness (the ability to become alert and focus on a task) and vigilance (sustained alertness).
Nowadays, increased alertness is directed towards communication and team training as an essential component of optimal management of obstetrical emergencies [ 6– 8].
Anatomically and physiologically the link between cardiovascular and hearing impairment due to structures responsible for cardiovascular regulation and components of ERPs that presents similar functions in the regulation of alertness and sensory attentional process is evident.
