简要总结
The autonomous response of fighter and attack pilots who attend sessions in a flight simulator will be evaluated by measuring and analyzing heart rate variability (HRV).
详细描述
The autonomous response of fighter and attack pilots during emergency situations in a flight simulator will be assessed by measuring and analysing heart rate variability (HRV). Eighteen pilots with instructor or student status assigned at the time of the evaluation to the ALA 23 district of the Talavera la Real Air Base of the Ministry of Defence of the Spanish Government (Badajoz) were studied during emergency situations in flight simulator. Subjects were assigned by non-probabilistic randomisation to an instructor group (IG; 7 subjects), and to a student group (AG; 11 subjects).
The recording of the parameters indicated corresponds to the emergency situations described above. Data collection was made in three different moments:
- Take-off: it starts after reading the checklist until the engine fault is resolved.
- Flight: during manoeuvres characterised by the recovery of abnormal positions.
- Landing: where the pilot performs the landing manoeuvre, with the loss of spatial situation.

结局指标
主要结局
Sympathetic/parasympathetic ratio (S/PS)
时间窗: 1 week
It is also described by Naranjo-Orellana et al., S/PS is expressed as the quotient of SS and SD1, and it is considered to reflect autonomic balance - that is, the relationship between sympathetic and parasympathetic activity
Root Mean Square of the Successive Differences (RMSSD)
时间窗: 1 week
It indicates the degree of activation of the Parasympathetic Nervous System on the cardiovascular system. It is obtained from the square root of the mean value of the sum of the squared differences of all successive RR intervals. This parameter reports the short-term variations of the RR intervals. It is directly associated with short-term variability.
Stress Score
时间窗: 1 week
It is an index described by Naranjo-Orellana et al. to facilitate physiological interpretation of Poincaré plot. It is expressed as the inverse of the SD2 diameter multiplied by 1000 and is considered directly proportional to the sympathetic activity in the sinus node.
