Abstract

The purpose of this study was to investigate intake of protein supplements by university students majoring in physical education. Intake experience rate, reasons for intake, purchasing place, effectiveness, satisfaction level, and side effects were analyzed using a questionnaire. Of 476 students, those who consumed protein supplements were 198 (41.6%). Male's intake experience rate was significantly higher than that of females, and members of health-related clubs also consumed more protein than non-members. The main purchasing place was internet shopping malls, and users obtained information from their friends or upperclassmen. The most frequently consumed protein supplement was 'WPH', and the most frequent reason for intake was 'building muscle or maintaining body shape'. For effectiveness, 'normal' was 49.0% and 'effectiveness' was 33.3%. For satisfaction, 'satisfaction' was 45.5% and 'normal' was 43.4%. The rate of side effects was 44.9%, and digestive issues such as diarrhea and indigestion were observed with high frequency. The results of this study show that education is needed for nutritional knowledge, adequate intake, and side effects of protein supplements.

본 연구에서는 체육교육전공 대학생들의 단백질 보충제 섭취실태를 살펴보고 이에 대한 기초자료를 마련하고자 하였다. 서울, 경기, 충청 지역의 9개 대학, 체육교육전공 대학생들을 대상으로 설문조사를 실시하여 총 476부를 자료 분석에 사용하였다. 단백질 보충제의 사용경험이 있는 사람은 41.6%, 사용경험이 없는 사람은 58.4%였으며 성별(P<0.001), 학년(P<0.05), 참여운동(P<0.001), 가입 동아리(P<0.01)에서 단백질 보충제 섭취경험 유무의 분포가 유의한 차이를 보였다. 단백질 보충제의 구매 장소로는 인터넷 쇼핑몰(71.7%)이 가장 많았고, 가장 높은 섭취 경험율을 보인 단백질 보충제는 WPH(39.4%)이었다. 단백질 보충제에 대한 정보는 친구나 선후배(56.6%)로부터 가장 많이 얻는 것으로 조사되었고 다음이 인터넷(44.4%)이었다. 단백질 보충제를 섭취하는 이유로 몸매나 근육 만들기를 가장 많이 들었고(48.5%), 남학생의 경우 몸매나 근육 만들기가 과반수 이상(57.7%)이었으며, 여학생은 운동능력 향상(33.3%)과 몸매 만들기(30.3%), 체중조절(30.3%)이 고른 분포를 보였다. 단백질 보충제의 섭취 효능에 대하여 '보통'이 49.0%, '효과있음'이 33.3%였으며, 만족여부에서는 '만족함'이 45.5%, '보통'이 43.4%였다. 단백질 보충제의 부작용 경험율은 사용자의 44.9%였고, 부작용에는 설사(30.3%), 소화불량(29.2%) 등 소화기 질환의 빈도가 높았다. 본 연구 결과 체육전공 대학생들은 단백질 보충제 섭취 이유로 몸매나 근육 만들기를 가장 많이 들었는데, 체육 전공자가 단백질 보충제를 운동능력 향상이나 영양보충 이외에 미용 상 목적으로 사용하는 것에 대한 다방면의 인식이 필요하며, 이의 오용이나 남용을 막기 위한 영양교육이 요구된다. 또 학생들이 전문가가 아닌 친구와 선후배, 인터넷을 통해 얻고 있는 단백질 보충제 정보의 정확성과 신뢰도를 높이기 위하여 학생들이 의사나 영양사 등 전문가로부터 정보를 얻을 수 있도록 교육과 올바른 정보 전달이 필요하다. 전문매장이 아닌 인터넷을 주된 구매 장소로 이용하는 것 또한 상업적 판매 위주나 불량품 및 부적절한 상품의 판매가 문제될 수 있다. 단백질 보충제 사용자의 44.9%가 경험한 부작용에 대하여 건강상의 문제도 우려된다. 따라서 지나친 상업적 판매 및 부작용에 대한 면밀한 조사와 과학적인 연구가 뒷받침되어야 하며, 품질보증제도 등의 제도적 장치가 마련되어야 할 것이다. 몸매나 근육 등 외모를 중시하는 사회적, 문화적 경향과 단백질 보충제에 대한 잘못된 정보가 전문 운동선수뿐만 아니라 일반인들에게도 무분별한 단백질 보충제의 섭취를 도모하는 결과를 초래할 수 있다. 특히 헬스 등 근력운동을 하는 경우에는 단백질 보충제와 관련된 영양교육과 올바른 정보 제공이 요구된다. 앞으로 단백질 보충제에 대한 섭취방법, 영양효능, 부작용 등의 다양한 정보와 지식 및 이에 대한 홍보가 필요할 것으로 사료된다.
