摘要

目的：肌肉型態是否影響階梯式負荷能量提供路徑。方法：受試者為一般人（8名），平均年齡為32±4.7歲，身高與體重則分別為175.3±6 cm、72.4±11.2 kg。每周平均運動次數為1.8±0.9次，每次為68.6±38.3分鐘。研究測試個人有氧閾值與NH3 Inedx測驗。開始速度為2.5m/s，每階持續時間5分鐘，每階速度上升0.3m/s 每次間歇30s。肌肉型態測試，個人以最大速度衝刺75m及1000m。分別在測試前採安靜值血液，測驗結束後採集生物參數。實驗結果：不論是高ST或FT的肌纖維型態，接受階梯式負荷後對乳酸堆積無正相關之影響。

Objective: to investigate the effect of muscle types on the energy providing pathway during progressive load. Methods: The subjects were normal healthy adults (n=8), with an average age of 32 ± 4.7 years, height and weight were 175.3 ± 6 cm, 72.4 ± 11.2 kg respectively. They performed 1.8 ± 0.9 sessions per week in average with 68.6 ± 38.3 minutes in average for each time. Current study evaluated individual aerobic threshold and NH3 Inedx tests. The initial speed was set at 2.5m/s. The speed increased 0.3m/s evary 5 minute with a 30 sec rest. For the muscle type test, each individuals sprint for 75m and 1000m at their maximum capacity. Blood was collected beofre tesing while the biological parameters were collected after the tests. Experimental results: Either ST nor FT muscle fibers revealed no positive correlation in terms of lactic acid accumulation.
