This paper uses research from two projects, conducted for Sport England and for the Central Council of Physical Recreation (CCPR), to analyze pressures on volunteers in sport in the United Kingdom (UK). Both research projects were contract research, conducted to inform policy and therefore were not designed to build on theoretical insights. However, from the results the research developed an understanding of the interrelated pressures on the voluntary sector in sport, which was informed by theory. This paper describes the pressures and relates them to previous research into volunteers. Contextualizing the issues faced by volunteers in sports organizations suggests several questions for further academic work, not only focussed on sports volunteers, but the voluntary sector in general. In particular, are the pressures experienced by the voluntary sector in UK sport common to sports volunteers in other countries, and to what extent are they also a reflection of general pressures on the voluntary sector?
