走り高跳び ('high jump,' lit. 'running high-jump') is one of two jump events in track-and-field — paired with 走り幅跳び ('long jump'). 樹立する ('establish, set up') is the formal verb for setting records — 記録を樹立する is the fixed collocation. Built from 樹 ('tree') + 立 ('stand'), the verb's literal sense is 'erect like a tree.' Used in news, sports, and historical contexts for landmark achievements: 世界記録を樹立する, 政権を樹立する ('establish a regime').
