ABSTRACT
Background and Objectives: Resistance training in the form of concentric and eccentric exercise is a highly recommended form of exercise for athletes and an individual with or at risk of cardiovascular diseases. So the purpose of this study was to compare the effect of exercise intensity on cardiovascular changes during concentric and eccentric resistive knee extension exercise on healthy males. Methods: A sample of 50 healthy subjects between the age group (18-25 years) were randomly selected and divided into 2 groups, A (concentric exercise) and B (Eccentric exercise). Each group exercised knee extension at 3 different intensities 75% of 1 RM, 85% of 1 RM, 1 RM). 5 minutes warm up was given and 5 minute rest was given after each exercise. SBP, DBP, HR, MAP and RPP were measured before and after each exercise. Results: Statistical analysis done with related t-test and unrelated t-test. Both the group improved but significantly more improvement was seen in concentric group when compared to eccentric group. Conclusion: The result of the study suggests that eccentric exercise produce lower cardiovascular response than concentric exercise.
ABSTRACT
Background & objectives: Children with sickle cell disease require more frequent hospital care and younger children (<5 yr of age) are more vulnerable to mortality. There are limited data on the events leading to hospitalizations and death in younger children with sickle cell disease from India. This study was, therefore, undertaken to evaluate the morbidity pattern in hospitalized under five children with sickle cell disease in a tertiary care hospital in Maharashtra, India. Methods: This was a prospective observational study carried out from July 2007 to June 2009. Hospitalized children below five years of age with sickle cell disease were enrolled for the study and evaluated for morbid event/s leading to hospitalization. Haematological indices were noted at baseline (most recent past when patient was not acutely sick) and at the time of hospitalization. Results: Eighty five children with sickle cell disease were hospitalized during the study period. Hospitalization with acute febrile illness (31%) was the most common morbid event followed by severe anaemia (30%) and acute painful events (20%). Majority (62%) of the events occurred between August and October. Forty five patients had foetal haemoglobin (HbF) more than 20 per cent (26.80±4.81%) and morbidity was significantly less in these patients. Interpretation & conclusion: Acute febrile illness was the most common morbid event followed by severe anaemia and acute painful event hospitalized children with sickle cell disease. There was significant seasonal variation with maximum events occurring in the monsoon season.
ABSTRACT
Objective: To study various determinants of hypertension in faculties of various colleges in Bhavnagar city. Method: The present study was conducted among faculties of various colleges in Bhavnagar city. Total 407 faculties were enrolled in the study. Diagnosis of hypertension was done according to JNC VII criteria. Result: We found 27.5% prevalence of hypertension among the faculties. Non modifiable determinants of hypertension like age, gender and family history of hypertension were significantly associated with hypertension. Modifiable determinants of hypertension like smoking, extra salt intake, sedentary life style, co existence of diabetes mellitus and Obesity (BMI ≥25 kg/m2) were significantly associated with hypertension. Conclusion: Hypertension is a major health problem and both non modifiable and modifiable determinants affect hypertension.
