Performance times of distance runners were predicted bassed on the 16-km time differential trail (2004) and 20-km grouped trial (2005) runs on the same training course before Hakone-Ekiden event. From these data, predicted and target performance times were estimated by using changes in split time (min/5km) and surplus performance for each distance runner after the trials. After the Hakone-Ekiden event, actual performance time for each distance runner was obtained and the errors (predicted performance time-actual performance time, and target performance time-actual performance time) were calculated. Errors were indices of accurate estimation of each performance time in Hakone-Ekiden event. The split time (min/5km) in 16-km time differential trial run showed large individual difference at the end of the trail. However, the 20-km grouped trial run exhibited small individual difference at 15-km and at even 20-km the deviation was relatively small. Predicted performance times were more accurate for the 20-km grouped trial run than for 16-km time differential trial run. Based on these results, 20-km grouped trial run was more suitable for to the prediction of actual performance times for distance runners in the Hakone-Ekiden event.

The purpose of this study was to determine whether hyperoxic gas inhalation following anaerobic exercise hastens recovery or enhances subsequent performance. Eight male and four female university students performed two bouts of bench press exercise to exhaustion at 70% of 1RM (performance test: PT-1 and 2). Interval of two exercises was separated by a 30 min recovery period during which the subjects breathed either room air (NOX) or hyperoxic gas (60% O2 in nitrogen: HOX) for 20 min (1-21 min of recovery time). The entire procedure was repeated on each subject using the opposite gas on another day. The work load in PT was 41.3+10.9 kg (70.2% of 1RM). The numbers of repetition of bench press in NOX and HOX conditions were 15.0+4.7 and 14.5+4.4 repetitions in PT-1, and 13.7+4.1 and 13.0+4.0 repetitions in PT-2 (NOX, -8.7%: HOX, -10.3%), there were no significant differences between both conditions, respectively. The changes of blood lactate concentration and its peak values (NOX, 4.00+1.08 mM: HOX, 3.90+0.88 mM) during recovery periods were not significantly different between NOX and HOX conditions. In conclusion, these data indicate that hyperoxic gas inhalation offers no advantages on recovery from exhaustive anaerobic exercise or on subsequent exercise performance.

The purpose of this study was to investigate the effect of. "TANDEN"-breathing (which is one of an adminal breathing method is used,by KOBUJYUTSU training) on blood lactate after high intensity running exercise. Thirty healthy basketball players of high school student participated in this study. They were separated to control group and "TANDEN" group and the "TANDEN" group trained TANDEN-breathings for 30 days. The exercise test underwent 3 times, (before beginning training, 15 days and 30 days after training.) Their blood lactate were measured on 0, 10, 20 and 30 minutes after the high intensity running exercise. There were no differences among training periods in control group. In TANDEN group, there were significant differences among training period, (p < 0.05) In comparision with control group,the decreasing rate of blood lactate were significantly grater in TANDEN group, (p < 0.05) These results suggest that to control breathing after high intensity exercise is effective to remove blood lactate which made by high intensity exercise in a short time.
