Exercise is inevitable to keep health in good status. There are few scientific studies to show the differences between different types of exercises in health and disease. In our study we compared the treadmill exercise and bicycle ergometer exercise and their effect on maximum heart rate attained, systolic blood pressure and diastolic blood pressure in twenty one healthy volunteer aged between eighteen to twenty years. We recorded these subjects?s blood pressure before exercise and after exercise; heart rate before exercise, during exercise and after exercise. Also we enlisted the advantages and disadvantages of treadmill exercise and bicycle ergometer exercise, so that these two types of exercise can be appropriately used for health promotion, diagnosis of diseases and for rehabilitation of the individuals.

\section[{Introduction}]{Introduction}\par
xercises are advised for health promotion, and prophylaxis for many cardiovascular diseases and also for rehabilitation after an episode of disease. Among the exercises aerobic exercises are appropriate for these purposes. To do aerobic exercise many methods are available for example: running, jogging, walking, cycling and others. Among different modes of exercises in the modern busy life, the bicycle ergometer and treadmill exercises are the commonest to perform as indoor aerobic exercises. In motor driven treadmill exercise which is similar to walking or jogging or running depending upon the speed of the treadmill motor. In case of bicycle ergometer exercise similar to cycling, the amount of exercise can be controlled voluntarily by pedaling the cycle with predefined resistance. Bicycle ergometer exercise and treadmill exercise will save the time to go to open space to perform aerobic exercises and space utilized for the same were also less. Apart from regular exercise these methods are also used in the performance of multistage sub-maximal or maximal stress testing \hyperref[b0]{(1)}. Both treadmill and bicycle ergometer exercise have their own advantages. But, in long term exercise practices interchanging of treadmill and bicycle ergometer exercise is not advisable especially if it was advised as therapy.\par
Hence present study was undertaken to study the cardiovascular responses for treadmill exercise and bicycle ergometer exercise. 
\section[{II.}]{II.} 
\section[{MATERIALS AND METHODS}]{MATERIALS AND METHODS}\par
The present study was conducted in semi urban city of south India, after obtaining institutional ethics clearance. The procedure was explained to the subjects and were recruited after obtaining informed written consent. For this study twenty one male volunteers were recruited. These subject's detailed history and general physical and clinical examination was done to rule out any underlying disease. Subjects with any known medical or surgical illness or physical disability were excluded from this study.\par
The age group of subjects was ranged between 18 years to 20 years. These twenty one male subjects were not trained athletes or sportspersons and were not taking any medications. Between 9am to 11am each subjects underwent exercise tests for two days. They had light breakfast atleast 3 hours prior to exercise testing and atleast 24 hours of abstinence from any form of alcohol, tobacco, tea, coffee. They had not under gone any strenuous work or exercises before test. Subjects were divided into two groups randomly by picking the folded covered slips into group A and Group B. There were 10 subjects in group A and 11 subjects in group B. Test was performed for each subject in two days. Group A performed treadmill exercise and Group B performed bicycle ergometer exercise on the first day. On next day the exercising group were interchanged i.e. Group A performed bicycle ergometer exercise and Group B performed treadmill exercise. Cardiovascular parameter like blood pressure was recorded by using mercury sphygmomanometer and heart rate was counted by auscultating at the apex of heart. BP and HR were recorded at resting state and immediately after the exercise. For this study we used a motor driven treadmill and mechanically braked bicycle ergometer. Comparison of different cardiovascular parameters between treadmill and bicycle ergometer exercise were made at equivalent oxygen uptake values (2) i.e. at 17.5 ml / kg / min oxygen uptake (1;3). In treadmill exercise subjects were made to walk at the speed of 1.7mph\par

There are few scientific studies to show the differences between different types of exercises in health and disease. In our study we compared the treadmill exercise and bicycle ergometer exercise and their effect on maximum heart rate attained, systolic blood pressure and diastolic blood pressure in twenty one healthy volunteer aged between eighteen to twenty years. We recorded these subjects's blood pressure before exercise and after exercise; heart rate before exercise, during exercise and after exercise. Also we enlisted the advantages and disadvantages of treadmill exercise and bicycle ergometer exercise, so that these two types of exercise can be appropriately used for health promotion, diagnosis of diseases and for rehabilitation of the individuals.\par
(2.8km/h) at 10 degree elevation for 3min (1;3). In bicycle ergometer exercise pedaling is done at the speed of 60 times / min, with breaking resistance of 1.75kg, for 3min to do work done of 450kpm / min (1;3). 
\section[{III. RESULTS}]{III. RESULTS}\par
Results of the present study are elaborated in Table  {\ref 1} IV. DICUSSION Body response to exercise depends on the type of exercise. Cardiovascular changes again depend on the type of exercise and severity of exercises. Cardiovascular responses differ in bicycle ergometer exercise and treadmill exercise as the method of exercise, exercising muscles and others (as listed below) differ. Other studies have shown that increase in heart rate was more in treadmill exercise compared to bicycle ergometer exercise  {\ref (2;4-6)}. Systolic blood pressure will increase more in treadmill exercise compared to bicycle ergometer exercise  {\ref (3;5)}. Diastolic blood pressure decreases in both type of exercises but the decrease was same in both groups  {\ref (3;5;7)}. Change in blood pressure and heart rate response in treadmill exercise was more compared to bicycle ergometer exercise for a given equivalent oxygen uptake values due to more sympathetic activation.\par
Difference between treadmill exercise and bicycle ergometer exercise: ? Bicycle ergometer is more economic compared to treadmill, ? Bicycle ergometer occupies less space compared to treadmill, ? Bicycle ergometer does not require electricity to run where as treadmill does require electricity, ? Upper body motion is less in bicycle ergometer, hence easy to record the vital signs and to collect blood samples (8), ? Bicycle ergometer is less familiar compared to treadmill walking (1), ? Subjects body weight does not influences the exercise capacity in bicycle ergometer whereas work rate is dependent on body weight in treadmill exercise (9), ? Smaller muscle mass is involved in bicycle ergometer exercise \hyperref[b9]{(10)}, ? Work load in bicycle ergometer exercise is controlled by subjects themselves, by controlling the speed of pedaling; but in treadmill it is controlled by observer, hence yield more reproducible data (1), ? Exercise output can be better quantified with bicycle ergometer exercise (1), ? Breathing is easier in treadmill exercise \hyperref[b10]{(11)}.\par

\section[{CONCLUSION}]{CONCLUSION}\par
Therefore when advising exercise for subjects his condition and requirement has to be taken into consideration. Detailed study regarding the same still has scope for research.			\footnote{© 2012 Global Journals Inc. (US)} 			\footnote{© 2012 Global Journals Inc. (US) © 2012 Global Journals Inc.
