Golf has been recommended as a relatively risk-free form of exercise for an ageing population. The aim of this study was to investigate the effects of playing a round of golf on mood states in recreational players. Ageing male golfers (N = 34; Age: M = 68.7, SD = 5.4 years) completed a mood measure immediately before and after an 18-hole round of golf. Distance walked per game was measured using a pedometer. Results indicate reported scores on Anger, Depression, and Fatigue increased and Vigor reduced following the game. However, it should be noted that although there was an increase in unpleasant mood states, this should be seen in the context of the overall mood profile, which was positive. Pedometer results indicated golfers walked a mean distance of 10.21 km (± 1.11). Results show participants of this age-group engaged in a meaningful exercise session and that mood scores deteriorated following play. Findings from the present study show that elderly golfers experienced mood profiles following golf similar to younger athletes following competition. For golf to be recommended as an activity for promoting physical activity among an aging population, the player’s ability to regulate unpleasant mood states should be considered. Future research should investigate the effects of experiencing negative mood states following golf on motivation to participate.
