A study was conducted to examine the relationship between the physical characteristics and race patterns of 400-m running in three elite 400-m runners.The experiments were composed of a physical fitness test and an analysis of 400-m race patterns.Maximal O_2 intake, maximal anaerobic power, isokinetic muscular endurance and isokinetic maximum muscular power were evaluated in a laboratory.Final 400-m races in the Japan Championship and the National Sports Festival were filmed using video cameras, and analyzed to calculate the changes in running speed during the 400-m distance.In accordance with the race analysis results, the three 400-m runners were divided into two types.One was the "even pace"type, which showed a tendency to maintain a higher running speed until the finish of the race.The other was the "first half"type, which showed the highest speed from the start until the 190-m point.The even pace type had a higher maximal O_2 intake and isokinetic muscular endurance of the lower limbs.The first half type was a good record holder over 100-m and 200-m distances.These results indicate that physical characteristics influence the race pattern of 400-m running.
