초록
본 연구는 심혈관 및 정형외과적 질환이 없는 23명의 건강한 성인 남성을 대상으로 일회성 유산소운동 중재 후 머리 tilt각이 자율신경조절에 미치는 영향을 규명하기 위한 목적으로 수행되었다. 무작위 교차설계인 총 세 번의 실험은 중강도의 유산소운동 후 tilt 테이블에서 누운 자세(supine, SUP), -15°head-down tilt(HDT), 또는 +15°head-up tilt(HUT)처치에서 회복기 20분 동안(Rec1,0~10분; Rec2,10~20분)의 HRV 모니터링으로 구성되었다. 기록된 r-r intervals는 HRV software Kubios 2.0을 통해 시간, 주파수, 비선형영역지수로 산출되었다. 운동 후 회복기 머리 tilt 각이 ANS 균형 회복에 미치는 영향을 평가한 후 다음과 같은 결과를 도출하였다. 먼저, 운동 중단 직후 및 회복기 20분 동안 tilt 각에 따른 심박회복에서는 유의한 차이가 나타나지 않았다(p > .05). 또한, 스펙트럼분석에서 SNS를 반영하는 지표(LF/HF ratio, LF nu) 및 PNS 재활성화 지표(HF power, HF/TP ratio, HF nu)는 tilt 각에 따른 통계적인 유의한 차이가 있었으며(p < .05), HUT에 비해 HDT에서 유의한 증가가 나타났다(p < .05). 반면 LF/HF ratio 및 LF nu는 HUT에 비해 HDT에서 유의하게 감소함을 나타냈다(p < .05). 더욱이, 반복측정분산분석 결과, HF/TP ratio를 제외한 모든 SNS 및 PNS 활성 지수들은 회복시간경과와 tilt 각에 따른 주효과 검정에서 유의한 차이가 있었다(p < .05). 결론적으로, 일회성 유산소운동 직후 회복기 –15°tilt 의 HDT 처치는 신속한 PNS 재활성화 및 SNS 저하를 유도하였을 뿐 아니라 HDT 처치가 교감-미주신경밸런스에서 우세한 PNS 재활성화를 유도한다는 사실을 객관적으로 검증하였다는 점에서 유의미한 결과를 도출했다. 따라서 심혈관 건강을 위해 운동 후 회복기 –15°HDT 처치는 심장 ANS 균형 회복을 위한 효율적 임상전략임을 시사한다.
Abstract
This study was aimed at investigating the effect of head-tilt angle on autonomic nerve modulation immediately after a single bout of exercise in twenty-three healthy young males(age 21.96 ± .4 yrs). Post-exercise HRV was measured on supine(SUP), -15°head-down tilt(HDT), and +15°head-up tilt(HUT) followed by 20 min aerobic exercise with moderate intensity(40% of VO2max). As results, heart rate recovery during post-exercise on each tilt angle(SUP vs. HDT vs. HUT) had no significant difference(p > .05). Also, there were no significant difference in time and nonlinear domain index of HRV. On spectral analysis; however, frequency domain index(HF, LF/HF ratio, HF/TP ratio, HF nu, LF nu) had significant difference(p < .05) on each tilt angle at recovery. Especially, PNS reactivation index (HF, HF/TP ratio, HF nu) had significant increase on HDT compared to HUT(p <. 05) while SNS activation index (LF/HF ratio, LF nu) had significant decrease on HDT compared to HUT(p <. 05). Furthermore, there were significant interaction between recovery time elapsed and each tilt angle (except for HF/TP ratio). In conclusion, -15°head-down tilt promotes the effective cardiac vagus nerve reactivation immediately after a single bout of aerobic exercise.
