Abstract

The purpose of this study was to investigate the effect of Forest-walking exercise on gait pattern in the elderly. The subjects (n=37) were assigned to 2 groups: Forest-walking exercise (FWE) group (n=19, $66.34{\pm}4.31$ years old) and In-door treadmill-walking exercise (ITWE) group (n=18, $67.18{\pm}2.78$ years old). The subjects participated in FWE program or ITWE program (3 times/week, 80 min/day) for 12 weeks. The subjects were tested on functional fitness (strength, endurance, agility/balance, BMI) and gait pattern (cadence, velocity, and stability) at the beginning and the end of the 12-weeks program. For data analysis, mean and standard deviation scores were calculated, and independent t-test and repeated two-way ANOVA were used. The results of this study were as follow: First, FWE group was significantly more improved than ITWE group on functional fitness(lower-body muscular strength, lower-body flexibility, mobility, cardiorespiratory endurance) after 12-weeks exercise program. But both groups showed equally improvements on functional fitness (upper-body muscular strength, upper-body flexibility, BMI). Second, FWE group was significantly more improved than ITWE group on cadence, gait velocity, and gait stability after 12-weeks exercise program. Therefore, this study may suggest that Forest-walking exercise based on sensory-motor functional integration improves efficiently functional fitness and gait pattern in the elderly, and further becomes an effective exercise method that makes more dynamic life, and prevents from falling.

이 연구는 노인들을 대상으로 산림 걷기 운동이 어떻게 기능적 체력과 보행형태에 영향을 미치는지를 규명하고자 하는데 목적이었다. 본 연구를 위하여 37명의 노인들이 참여하였으며 산림 걷기 운동 집단(n=19, $66.34{\pm}4.31$세)과 실내 트레드밀 걷기 운동 집단(n=18, $67.18{\pm}2.78$세)으로 구분되어, 12주간 주에 3회 80분 씩 각각 산림 걷기 운동과 실내 트레드밀 걷기 운동에 참여하였다. 기능적 체력(근력, 지구력, 유연성, 민첩성/평형성, BMI)과 보행형태(보행박자, 보행속도, 보행안정성) 검사는 12 주간 프로그램 전과 후에 측정되었다. 자료 분석을 위하여 평균과 표준편차가 이용되었으며, 독립 t-test와 반복 이원변량분석이 이용되었다. 그 결과, 12주간의 산림 걷기 운동을 실시한 집단이 실내에서 트레드밀 걷기 운동한 집단보다 하지 근력, 허리 유연성, 민첩성/동적 평형성, 그리고 심폐지구력에서 더 크게 향상을 보였다. 그러나 상지 근력, 견관절 유연성, BMI에서는 두집단 모두 똑같은 향상을 보였다. 둘째, 12주간의 산림 걷기 운동을 실시한 집단이 실내에서 트레드밀 걷기 운동한 집단보다 보행박자, 보행속도, 보행안정성에서 더 유의한 향상을 보였다. 따라서 본 연구는 감각-운동신경의 기능적 통합에 기초한 산림 걷기 운동이 노인들의 기능적 체력과 보행형태를 효율적으로 향상시키고, 나아가서 생활을 더 역동적으로 만들며, 낙상을 예방하는 효과적인 운동방법이 될 수 있음을 제안한다.
