The purpose of the study was to examine the effect of moderate dose (5mg per kg) of caffeine ingestion on pulse rate, blood pressure(both systolic and diastolic) and energy expenditure (cal) during a steady state exercise period with a standardize power output as well as during a set time period, where participants were required to cycle with maximum effort. Eighteen healthy, overweight, sedentary, male, first year MBBS student of Jawaharlal Nehru Medical college (sawangi, wardha, Maharashtra) completed 15 minutes steady state cycling exercise at a standardized power output equating to 65% of HRmax (part-1) followed by 10 min stationary cycling where they were required to cycle with maximum effort after ingestion of caffeine (5mg per kg) 60 min prior to exercise. Same subjects were used as control. Systolic blood pressure was increased after caffeine ingestion but there was no significant change in diastolic blood pressure. Pulse rate decreased with moderate dose of caffeine ingestion during submaximal exercise which indicates decrease in heart rate. After caffeine ingestion energy expenditure in the 2nd part (10 min maximal) of exercise increased in very small amount but it is significantly increased in 1st part of exercise (15 min sub maximal exercise).
