Introduction: Long term physical training has been considered to adversely affect the performance of athletes especially the females. It may be due to the iron depletion caused by hemolysis or hemodilution results from plasma volume expansion. This study aims to assess the effect of heavy exercise on hemoglobin concentration and some other hematological parameters in female athletes.
Methods: This cross sectional study was carried out in the Department of physiology, Dhaka Medical College, Dhaka, from July 2010-June 2011. A total number of 105 females (70 athletes and 35 non athletes) between 15-25 years of age were recruited. The 35 apparently healthy female non athletes were taken as control (Group-A) and 70 female athletes comprise the study group (Group-B). According to sporting category, Group-B was further subdivided as B1:Runners and B2:Cyclists. Hemoglobin percentages (Hb %), red blood cell (RBC) concentration, packed cell volume (PCV), serum iron, serum ferritin and total iron binding capacity (TIBC) were measured in fasting state after two months training. Statistical analysis was done by using SPSS/ win.15.0 for comparison between the groups, using student’s unpaired “t” test.
Results: Mean Hb%, RBC, PCV, iron and ferritin level were significantly (P<0.001) lower in athletes than those of control group. Within the study groups, runner’s serum iron and ferritin level were lower than cyclists. TIBC significantly (P<0.001) rose in Group-B2 in comparison to Group-A.
Conclusions: The current study showed that intense physical exercise leads to early stages of Hb%, RBC, PCV, iron and ferritin depletion which might compromise the health and performance of athletes.

e: e: smokeless tobacco use might have influence on cardiovascular parameters, for instance pulse rate and blood pressure.Methods: Methods: Methods: Methods: Methods: This cross-sectional study was carried out to assess cardiovascular changes in among adult male smokeless tobacco (ST) users. For this purpose, 30 male respondents were selected. The participants were selected from medicine out patient department of Dhaka Medical College Hospital. Pulse rate and blood pressure was measured and ST use behaviour was assessed using self-reports. Statistical analysis was done by SPSS17.
Results:Results: Results: Results: Results: In this study, the mean (±SD) of pulse rate was 84.07±11.011beat/min. The mean (SD) of systolic blood pressure was 154.50 (SD26.79) mm of and the mean (SD) of diastolic blood pressure was 96.67(SD10.93) mm of Hg in smokeless tobacco users.
Conclusion Conclusion ConclusionConclusion Conclusion: Mean systolic and diastolic blood pressures were higher in smokeless tobacco users in the tertiary level hospital. However, mean pulse rate was within the normal range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
