Role of Professional Kinesiologists for Cancer Patients and Survivors
강서정 대한운동학회 2022 아시아 운동학 학술지 Vol.24 No.3
Cancer is the leading cause of mortality worldwide, including in Korea, and mortality continues to increase with the progress of a super-aged society. A support or care system to reduce psychological issues, such as anxiety and depression, is very important during cancer patient treatment, and this can be achieved by exercise. In addition, exercise can alleviate cancer treatment side effects, improve patients’ functional status, lead to better outcomes after surgery, build baseline strength to endure treatments, and prevent recurrence. The relationship between cancer and exercise is still being debated; however, many studies have shown that regular physical activity prevents cancer occurrence and reduces the risk of recurrence and death [1]. Also, those with greater physical activity showed lower risk for 13 types of cancer [2], and several cases of certain common cancers had a lower mortality rate [3]. Some researchers found that the degree of physical activity in colorectal or breast cancer patients had a significant association with risk and incidence rate [4]. These findings suggest that physical activity or exercise can have a strong positive effect on the health of cancer patients and survivors. Despite the benefits of exercise for such patients, cancer survivors living at least five years after cancer diagnosis still cannot recover to the normal state of health. To find causes for this, obstacles and preferences regarding physical activities of cancer patients and survivors were studied. The results showed that obstacles included poor physical strength, fatigue, fear of recurrence, stress, lack of motivation, economic burdens, family support, and knowledge and experience of exercise. The most preferred physical activity was low- to medium-intensity walking [5]. Regardless of the existence of studies and cancer mortality, educational and operational institutions and programs for professionals to guide proper exercise for cancer patients and survivors remain lacking. Many cancer survivors who lacked physical activity and experience with exercise reported that they could comprehend personal obstacles and preferences regarding exercise after regularly participating in exercise activities [6]. This is important because they could apply exercise programs and eventually gain motivation to exercise more regularly [7]. This suggests the importance of providing exercise opportunities for patients and survivors and emphasizes the role of professional kinesiologists. As cancer mortality increases and exercise’s benefits are emphasized, improving the professional competence of professional kinesiologists in this regard is highly recommended.

주관적 기억장애 및 경도인지장애 노인의 의미연상과제 수행 특성
강서정,박성현,김정완 한국디지털정책학회 2019 디지털융복합연구 Vol.17 No.2
The loss of semantic knowledge and impairments in semantic associations by semantic category is gaining increasing attention, as indicators of early-stage cognitive decline. As such, we assigned semantic association task (SAT) to normal elderly (NE) and those with subjective memory impairment (SMI) or mild cognitive impairment (MCI) to examine their performance by semantic subcategories and the differences in error patterns. We found a significant difference in the number of correct response and reaction time under the SAT categories among the three groups, with the highest performance observed in 'function' and the lowest performance in 'superordinate' and 'part/whole'. Moreover, the error frequency was the lowest in NE, followed by those with SMI and MCI, with the latter two groups showing a significant increase in no-response. Our findings demonstrate the varying extent and process of impairments in the semantic network by category over different stages of cognitive decline. Thus, we proposed SAT performance as an indicator to detect and follow-up on cognitive decline in elderly with cognitive disorder. 초기의 인지 감퇴를 판단하는 요소로 의미지식 및 의미 연관관계의 범주별 손상 유무가 주목을 받고 있다. 본 연구에서는 정상 및 주관적 기억장애, 경도인지장애 노인을 대상으로 의미연상과제를 사용하여 인지 감퇴의 정도에 따라 관찰되는 의미 하위범주별 수행과 오류유형의 차이를 살펴보고자 하였다. 연구 결과, 의미연상과제 범주별 정반응 점수와 반응시간에서 세 군 간 유의한 차이를 보였으며, 하위범주 중, ‘기능’에서 가장 높은 수행력을, ‘상위’와 ‘부분/전체’에서 가장 낮은 수행력을 보였다. 또한, 오류유형별 산출 횟수는 정상에서 경도인지장애 노인으로 갈수록 유의하게 높아졌으며, 무반응은 주관적 기억장애 노인부터 유의하게 증가하였다. 결론적으로, 인지 감퇴가 진행될수록 의미연결망에서 범주별 손상의 정도와 과정이 다르므로, 기억장애 노인의 인지적 감퇴를 확인하고 추적 관찰하기 위한 지표로 의미연상과제 수행력을 활용할 수 있을 것이다.

보행 시 백팩 부하에 따른 시·공간 변인, 몸통과 어깨 근육의 활동성과 피로도
강서정 대한운동학회 2013 아시아 운동학 학술지 Vol.15 No.1
[INTRODUCTION] The purpose of the study was to investigate how different load weights(0, 10, 20, & 30% BodyWeight(BW)) affect spatiotemporal parameters in gait, trunk and shoulder muscles activity and fatigue. [METHOD] Ten healthy male subjects(Age: 26.9±2.2yrs, Height: 179±5.73cm, Weight: 76.2±5.8kg) were participated in the study. In order to get the spatiotemporal parameters, cameras, markers and Visual 3D program were used. The activity and fatigue in four muscles(Upper Trapezius, Lower Trapezius, Rectus Abdominis, & Erector Spinae) were analyzed with using Wireless EMG System. One-way repeated measures ANOVA and LSD(Post-Hoc) were used to analyze the effects of different load weights on spatiotemporal parameters, trunk and shoulder muscles activity and fatigue. [RESULT] Spatiotemporal parameters(velocity, step length, & stride length) did not show any significant difference. Lower Trapezius muscle showed significant differences on different load weights. The fatigues in Rectus Abdominis and Erector Spinae showed significant differences at over 20%BW load weights. [CONCLUSION] The backpack load in over 20%BW caused more fatigues of trunk muscles than shoulder muscles. Therefore, it might be considered in backpack design. [서론] 본 연구의 목적은 보행 수행 시 백팩 부하 변화(0, 10, 20, & 30% BodyWeight(BW))에 따른 몸통과 어깨 근육의 활동성과 피로도, 시․공간 보행 변인의 변화를 분석하고자 하였다. [방법] 건강한 성인 남성 10명(연령: 26.9±2.2세, 키: 179±5.73cm, 체중: 76.2±5.8kg)이 연구에 참여하였다. 시․공간 보행 변인을 얻기 위해 카메라, 마커, Visual 3D 프로그램이 사용되었고, 위등세모근, 아래등세모근, 배곧은근, 척주세움근의 활동성과 피로도 분석을 위해 무선근전도 시스템이 사용되었다. 백팩 부하 변화에 따른 변인의 변화를 분석하기 위해 one-way repeated measures ANOVA가 사용되었고, 사후분석 검정으로 LSD 를 사용하였다. [결과] 백팩 부하 변화에 따라 시․공간 보행 변인은 통계적으로 유의한 변화를 나타내지 않았고, 아래등세모근의 활동성이 백팩 부하 변화에 따라 유의하게 변화하였다. 배곧은근과 척주세움근의 피로도가 백팩 부하 20%BW에서부터 유의하게 변화하였다. [결론] 20%BW 이상의 백팩 부하는 어깨 근육 보다는 몸통 근육인 배곧은근과 척주세움근에 피로를 유발시키는 것으로 나타나 백팩 디자인 시 고려되어야할 사항으로 생각되며, 오랜 시간 20%BW 이상의 부하로 보행을 하는 여행자나 군인들에게 배곧은근과 척주세움근의 강화가 필요할 것으로 사료된다.
