청년기 · 노년기 성인의 신체활동 참여가 정서인지에 미치는 영향 = The Influence of Participation of Physical Activity in Adolescence and Senescence Adults on Affective Cognition

다국어 초록 (Multilingual Abstract)

Physical activity has positive effects on cognitive functions by aging. However, it is rare to find research that have scientifically investigated the effects on the affective-cognitive function. Thus, this study aims to brainscientifically research its effects of physical activity on the affective-cognitive function of adults in adolescence and senescence. As subjects of this study, a total of 60 males adults in D region were selected, and then equally divided into four groups of young exercise group(25~35y/o), young non-exercise group(26~35y/o), old exercise group(60~70y/o), and old non-exercise group(60~70y/o). As experiment tools, the EEG measuring equipment and International Affective Picture System(IAPS) were used. The experiment of this study used an affective-cognitive task where subjects pressed a button depending on emotional valence(positive, neutral, negative) shown in thepictures. During the task, EEG measured eight areas(Fp1, Fp2, Fz, C3, C4, Cz, T3, T4) out of brain areas in accordance with the international 10-20 electrode system, EEG was measured. For statistical analysis, a three-way ANOVA on 4(group)×3(stimulus)×8(area) was conducted. The results showed main effects of group in both reaction time and accuracy, and also in the latency of P3. And there was an interaction between group and stimulus the amplitude of P3. In conclusion, Physical activity has positive effects on the affective-cognitive function of people in adolescence and senescence.

국문 초록 (Abstract)

신체활동은 노화로 의한 인지기능 저하에 긍정적 영향을 미친다. 하지만 신체활동 참여가 정서인지기능에 미치는영향을 과학적으로 밝혀 낸 연구는 드물다. 따라서 본 연구의 목적은 청년기와 노년기 성인의 정서인지 기능에 신체활동참여가 어떠한 영향을 미치는지를 뇌 과학적으로 연구하는 것이다. 연구의 피험자는 D 광역시 성인 남성 60명으로선정하였으며, 청년 운동 집단(25∼35살), 청년 비 운동 집단(26∼35살), 노년 운동 집단(60∼70살), 노년 비 운동집단(60∼70살) 4개의 집단으로 구성하였다. 실험도구는 EEG 측정 장비와 국제정서사진체계(International AffectivePicture System: IAPS)를 사용하였다. 본 연구의 실험과제는 사진으로 제시하는 세 가지 정서자극(긍정적, 중립, 부정적)에 적합한 버튼을 눌러 정서적인지 검사를 실시하였다. EEG 측정은 8개(Fp1, Fp2, Fz, C3, C4, Cz, T3, T4)의 영역을측정하였다. 통계처리는 4(집단)×3(자극)×8(영역)에 대한 삼원분산분석을 실시하였다. 결과: 본 연구 결과, 반응시간과반응정확률 그리고 P3 잠재기는 집단간 주효과가 나타났다. 그리고 P3 진폭은 집단과 자극간 상호작용이 나타났다.
결론: 신체활동은 청년층과 노년층의 정서적 인지기능에 긍정적인 영향을 미치는 것으로 나타났다.
