The physiological and physical preparations for the 1500m running event in training programs aim to develop specific endurance and both aerobic and anaerobic energy systems through hill training. Since specific endurance training compensates for the reduction in speed rate during performance, the significance of this research lies in understanding the extent of the impact of hill training (both ascending and descending) on specific endurance (speed endurance - strength endurance) and 1500m running performance, in order to achieve the best possible level of performance.
