This randomized controlled trial (RCT) aims to evaluate the physical and physiological demands, the feasibility and the health, physical fitness and disease-specific outcomes of a progressive recreational team handball-based programme in patients with lower extremity peripheral arterial disease and intermittent claudication. The primary outcomes will be changes in functional capacity, assessed by the 6-minute walk test. Participants will be randomized to either a 24-week progressive team handball-based intervention or a usual care control group, with assessments performed at baseline, 12 weeks, and 24 weeks post intervention to evaluate health, physical fitness, and disease- specific outcomes.
