Track and field sports included track, field, and combined events. Field events referred to jumping and throwing events held in the center or outskirts of the open field, enclosed by the running track. The high and long jump, as well as any throwing events, were measured for competition. Track events were any foot racing events held on the running track, such as sprinting. These events were timed for competition. Simply speaking, field events were aiming for distance, while track events were aiming for time. Combined events were composed of both field and track events.
In track events, only short-distance competitions required explosive power. In events like long distance running, endurance was more important. For field events, explosive power was needed for both jumping and throwing. Based on this information, Dai Li concluded that the explosive force halo would surely boost the performance of the shot put athletes.
