본 연구는 체육행정조직에서 리더의 변혁적 리더십과 거래적 리더십 유형이 조직구성원의 조직몰입과 직무성과에 미치는 영향을 규명하여 체육행정가의 보다 효율성 있는 리더십 행동 유형을 제시함과 동시에 효율적인 업무향상과 조직의 전략적인 인적자원관리에 기초 자료를 제공하는데 목적이 있다. 본 연구의 목적을 달성하기 위하여 우리나라 16개 시ㆍ도 체육회 사무처 직원을 대상으로 편의추출법(conveniet sampling method)을 활용하여 표본을 추출하였으며, 총 220명을 표집 하였으나, 불성실하게 응답한 24명을 제외하고 실제 분석에 사용된 사례수는 196명이었다. 본 연구의 분석을 위한 자료수집 방법으로 설문지법을 이용하였다. 연구에 사용된 설문지는 선행연구에서 사용된 조사도구를 기초로 하여 문항을 수정ㆍ보완하여 예비검사를 통하여 내용의 적합성과 적용 가능성을 검토한 후 그 타당도와 신뢰도를 검증하여 본 연구의 조사도구로 사용하였으며, 연구에 사용된 조사도구는 크게 네 부분으로 구성되었으며, 총 63개의 문항으로 구성되었다. 자료를 분석한 결과는 다음과 같다. 체육행정가의 변혁적ㆍ거래적 리더십은 조직구성원의 조직몰입과 직무성과에 유의한 영향을 미치며, 특히 거래적 리더십이 많은 영향을 미치는 것으로 나타났다. 조직몰입의 하위 변인인 규범몰입과 감정몰입은 직무성과에 유의한 영향을 미치고 있는 것으로 나타났다. 경로분석 결과 체육행정가의 변혁적ㆍ거래적 리더십은 직ㆍ간접적으로 조직몰입과 직무성과에 영향을 미치며 조직몰입은 직무성과에 직접적인 영향을 미치는 것으로 나타났다. 이상을 종합할 때 체육행정가의 리더십 유형은 조직구성원의 조직몰입과 직무성과에 직접적인 긍정적 영향을 미침을 알 수 있으며, 조직몰입을 통해 간접적으로도 직무성과에 영향을 미침을 경로분석을 통해 알 수 있었다. 본 연구를 통해 얻은 결론 중 특히 거래적 리더십이 조직구성원의 조직몰입과 직무성과에 더 큰 영향을 미친다는 사실은 기존의 선행연구와 다른 결과를 보여주고 있다. 지금까지 보고되어온 리더십 연구에 따르면 변혁적 리더십이 더 큰 영향을 미친다고 보고하였는데, 이러한 결과는 상업 스포츠 시설이나 일반 사설 스포츠조직을 대상으로 한 연구물들이었기 때문으로 사료되며, 연구대상들이 공무원과 비슷한 신분을 유지하고 정년을 보장받을 수 있는 집단을 대상으로 한 본 연구에서는 정해진 성과를 달성할 경우나 그렇지 못할 경우 그에 상응하는 보상과 결부된 거래적 리더십이 더욱 효과적임을 알 수 있었다.
