Twenty-one eligible runners will be randomly assigned to one of three training groups and will complete a 12-week intervention comprising 24 prescribed training sessions. The study will evaluate immediate responses to conditioning, 24-hour recovery responses, and cumulative changes in running performance, aerobic fitness, and training-related responses. Outcomes will include heart rate, blood lactate concentration, rating of perceived exertion, delayed-onset muscle soreness, recovery and wellness indicators, internal training load, 5-km time-trial performance, and VO₂max. The findings will provide evidence regarding the comparative responses to these three conditioning modalities in well-trained long-distance runners.",[29],"Long Distance Running",[31,32,33],"Fartlek Training","Hill Circuit Training","Roll-On Training","NOT_YET_RECRUITING","2026-08-25",{"date":37,"type":38},"2026-08-26","ACTUAL",{"date":40,"type":23},"2026-09-21",{"date":42,"type":23},"2026-11-26",{"name":44,"class":45},"Debre Markos University","OTHER",""]
