The Relationship Between Psychophysiological and Psychological Parameters of Job Stress and Working Capacity of Loggers in the North at the Beginning, Middle and End of the Shift Period

The study established the relationships between the psychological and psychophysiological parameters of job stress and working capacity of loggers at two divisions with different socio-psychological characteristics of teams in the north at various stages of the fifteen-day shift period. The study was conducted by two scientific expeditions to two forest plots simultaneously in July 2024, in which 47 loggers took part. Diagnostics of job stress and working capacity was carried out daily in the morning and evening using psychophysiological and psychological methods. Questionnaires assessed the socio-psychological characteristics of teams five times. Due to the greater stressfulness of the adaptation and fatigue stages at the end of the shift, a greater consistency of various assessments of the functional states of loggers at the beginning and end of the shift period was revealed compared to the more favorable period in the middle of the shift. At the same time, at the beginning and end of the shift period, separate multidirectional trends were established in the assessments of the functional state (VCM) and subjective comfort at the beginning of the period and the level of functional capabilities (VCM) and performance (M. Luscher's method) at the end of the period, which may indicate mechanisms of psychological mobilization (maintaining the functional state due to a positive self-perception) of workers. Loggers working in a team with positive socio-psychological characteristics are distinguished by a more favorable level of functional state during the shift period.
