이 연구의 목적은 8주간의 저항성 운동이 암 경험자들의 신체구성, 최대근력(1RM), 암관련피로도(CRF) 및 삶의 질(QOL)에 미치는 영향을 분석하는 것이다. 연구대상은 암치료 종료 후 5년 이하의 암 경험자들로, 의사로부터 저항 운동참여 허가를 받은 10명으로 선정하여 8주간, 주 2회, 회당 60분간 저항운동을 실시하였다. 측정변인으로 신체구성은 BIA법을 적용한 InBody270을 사용하여 Wt, SMM, BFM, %BF를 측정하였고, 론픽 미니플러스(Ronfic miniplus)를 사용하여 SCP, SR, BS, DL의 자세에서 1RM을 측정하였으며, CRF는 FACIT-F 설문지로, QOL은 FACT-G 설문지를 사용하여 측정하였다. 자료처리는 SPSS(ver. 29.0)를 이용하여 운동 전, 후 측정된 변인들의 평균(mean)과 표준편차(SD)를 산출하고, 전·후 시기 간 평균차이 검정은 대응표본 t-검정(paired t-test)을적용하였다. 그 결과, 모든 신체구성의 변인은 유의한 차이가 없었으며, 1RM은 SCP, SR, BS, DL 모두 증가하였다. 또한, CRF는 유의하게 감소하였고, 삶의 질(QOL) 항목의 PWB, EWB, FWB 및TS 점수가 유의하게 증가하였으나, SWB에서는 효과가 나타나지 않았다. 결론적으로, 저항성 운동은 암 경험자들의 최대 근력을 증진시키고, 암 관련 피로도를 감소시킴으로써 삶의 질을 향상시켜, 암 치료 후 삶의 질 회복에 긍정적인 기여를 할 수 있다.
Abstract
The purpose of this study was to analyze the effects of 8 weeks of resistance exercise on body composition, one-repetition maximum strength (1RM), cancer-related fatigue (CRF), and quality of life (QOL) in cancer survivors. The study subjects were 10 cancer survivors who were five years or less post-cancer treatment and had been cleared by their doctors to participate in resistance exercise. They performed resistance training for 60 minutes per session, twice a week, for eight weeks. As measurement variables, Body composition was measured using InBody270 with BIA method to measure Wt, SMM, BFM, and %BF; 1RM was measured using Ronfic miniplus to measure SCP, SR, BS, and DL postures; CRF was measured using FACIT-F questionnaire; and QOL was measured using FACT-G questionnaire. Data were processed using SPSS (ver. 29.0) to calculate the mean and standard deviation (SD) of the variables measured before and after exercise, and paired t-tests were used to test for differences in means between the pre- and post-periods. The results showed that all body composition variables were not significantly different, and 1RM increased SCP, SR, BS, and DL. In addition, CRF was significantly reduced, and the PWB, EWB, FWB, and TS scores of the QOL items were significantly increased, but there was no effect on SWB. In conclusion, resistance exercise can positively contribute to the recovery of quality of life after cancer treatment by improving maximal muscle strength and reducing cancer-related fatigue in cancer survivors.
