Abstract

Objectives: Physical activity can cause various hematological changes and affect blood parameters. The purpose of this study was to investigate the effect of diving in the morning and evening on the hematological factors of male divers.

Materials and methods: In this research, ten divers participated in this research. they did The participants dived at a depth of 10 meters on the first day, 20 meters on the second day, and 30 meters on the third day for 20 minutes with an intensity of 50-60% of the reserve heart rate in the morning and evening. Blood samples were collected before and after diving before and after diving. Analysis of variance with repeated measurements was used to analyze the findings.

Findings: The results showed that increasing ambient pressure has a significant effect on changes in hemoglobin (p=0.005), hematocrit (p=0.001) and red blood cells (p=0.003). Regardless of the depth, diving has a significant effect on hematocrit (p=0.01) and red blood cells (p=0.03). Hemoglobin levels (p=0.01), hematocrit (p=0.001) and Red blood cells (P=0.007) at a depth of 30 meters increase significantly compared to depths of 10 and 20 meters.

Conclusion: Diving in the morning and in the evening has the same effect on hemoglobin and red blood cells. On the other hand, diving at depths of 30 meters and 20 meters led to more changes compared to diving at a depth of 10 meters.
