研究发现,百米起跑阶段的速度发展包括了多种不同因素,这些因素构成了对比赛能力的不同要求。运动员对发令枪的实际反应则有赖于动作技术、反应速度和速度力量。随后的起始和加速阶段就需要跑动速度、速度力量、步频速率和肌肉的放松。一些研究已经表明,起跑后的加速阶段是决定比赛成绩的关键因素。世界级短跑选手所展示的“火箭喷射式”的加速跑说明了前10-15m加速能力的重要性。尽管良好的速度耐力在短跑中也扮演着重要角色．但是在起跑后第二阶段的强有力加速跑可以完全弥补速度耐力的不足。
The study found that speed development during the 100-meter start-up included a number of different factors that made up the difference in competency requirements. The actual reaction of an athlete to a starting gun depends on motor skills, reaction speed, and speed. Subsequent start-up and acceleration phases require running speed, speed power, pace rate, and muscular relaxation. Some studies have shown that the acceleration phase after starting is a key factor in determining race results. The “rocket-jet” acceleration run by world-class sprinters illustrates the importance of acceleration in the first 10-15 m. Although good speed endurance also plays an important role in dashing. However, in the second stage after the start of a strong acceleration can completely compensate for lack of speed endurance.
