A study of the psychophysiological reactivity of boys aged 13–14 years during mental performance at optimal and maximum rates showed that informational loading caused marked functional strain. The physiological cost of working at a comfortable rate was lower than at the maximum rate. Excessive psychophysiological reactivity was observed at the initial stages of puberty during intense mental loading. Such reactivity was responsible for a high physiological cost of adaptation and low functional capabilities of adolescents at puberty stages (PSs) II and III. Moreover, personality traits that contribute to mental strain were expressed to a greater extent in these adolescents. Comparisons indicated a tendency towards higher emotional stability and lower anxiety and frustration for the transition from PS II to PS IV. Excessive psychophysiological reactivity during intense mental work and a high psychophysiological cost of activity in adolescents at PSs II and III may decrease working efficiency, worsen the efficiency of learning, and cause adverse deviations in the state of health. This circumstance should be taken into account during elaboration of effective prophylactic measures aimed at optimizing the functional state of schoolchildren in puberty. [ABSTRACT FROM AUTHOR] |
