Abstract
This research is aimed to investigate the effect of repetitive dive on physiological reactions, pulmonary functions, blood constituents, and production and change of stress hormones in no decompression limit of sport SCUBA dive, an emerging recreational activity recently.

In order to compare physiological reactions prior to and after the initial dive and after repetitive dive at a certain depth of a place, eight adult male divers with more than forty dives, who reside in Busan and were certified, were selected.

The method of the research is that the sport divers selected the dive depth they dived most and planned the dive time within no decompression limit according to NOAA diving table (the first: at 24m maximum depth for 24 min. - the surface interval for 90 min. the second: at 23m maximum depth for 22 min.) and then dived twice. The measurement and blood gathering were carried out once before and after the first dive and at the end of the repetitive dive respectively.

The dive log was recorded by an M1(ITALY) dive computer, and the data was analyzed by repeated measure ANOVA using SPSS 12.0K/windows statistics program. The post-hoc analysis was conducted in the method of Bonferroni and the significance level was p<.05.

The research results obtained from the procedures described above are follows:

First, for physiological reactions, heart rates, temperatures, and systolic blood pressures had significant difference among prior to and after the initial dive and after the repetitive dive, while diastolic blood pressures did not show remarkable difference as it increased before and after the first dive but decreased following the repetitive dive again.

Second, for change of pulmonary functions, not enough of a difference to recognize ahead of and following the initial dive and after the repetitive dive as well as prior to and during the first dive and after the repetitive dive.

Third, for change of blood constituents, leucocytes, monocyte, eosinophil, and nasal basophile were indicated significant difference before and after the first dive and at the end of the repetitive dive, while the number of blood platelets and lymphocytes had no remarkable difference.

Lastly, for change of stress hormones, it was not significantly different prior to and after the initial dive and following the repetitive dive, as well as before and during the first dive and the repetitive dive.
