Abstract Introduction: The importance of physical activity, fitness on CVD risk factors are well established in western cohorts. However, there are no geographical cohorts available in India. Aims and objectives: It has formed to identify role of physical activity, fitness, yoga practice and other sedentary behaviors on the development of some CVD risk factors (i.e) hypertension, diabetes and obesity in urban Indian population. The secondary objective is improved physical activity, fitness behavior, yoga practice and reduced sedentary behavior on the prognosis of above said risk factors once it developed. Methodology: 1804 subjects (female 54.6%; response rate 71.9%) were selected through multi-stage random sampling technique in 6 different locations of urban Hisar city during summer 2016. Main eligibility criteria was age should be at least 30 years at the time of recruitment. Therapist assisted standard questionnaire was administered to collect baseline subjective data.Most of the outcome variables, muscular strength were measured objectively. Yoga practice; physical activity/sitting time through GPAQ are being measured now. Future plan: Aerobic fitness through Rockport 1 mile walk test will be measured within 2 years. Subjectively measured physical activity, ADL and sedentary behaviors will be validated through pedometers.Usage of mobile phone, physiotherapists to modify the behavior of subjects and its effect on development and prognosis of CVD risk factors will be studied future. Keywords: Cohort, Longitudinal study, Physical fitness, Chronic diseases, CVD risk factors I. Introduction Being physically active and fit has now shown many health benefits. [1, 2] Physicians in western countries are now even thinking of putting exercise as fifth vital sign for health assessment. [3] It all started from a land mark article from Framingham Heart Study in 1967 that reported protective effect of physical activity on coronary heart diseases. This leads to form another cohort in 1970-Aerobic center longitudinal study (ACLS) from Cooper institute with the aim to find health outcomes associated with physical activity and cardiorespiratory fitness. Later in 1985-86 CARDIA study started with an aim of aerobic fitness at young age on CVD risk factors, diseases and mortality.These two along with several other longitudinal studies confirmed the findings of Framingham Heart Study. Recent meta-analysis shows that fitness prevent better than BMI in all-cause mortality and advise the readers to concentrate on fitness than mere physical activity and weight reduction alone. [4] Resultsare showing sedentary behaviors like sitting time, TV watching associated with greater risk of CVD risk factors, all-cause mortality independent of physical activity. [5-7] However, there are few cohorts available from India on physical activity with two known to us-one from southern India (Kerala) [8] , one from north India (Haryana) [9] and few on physical fitness (hand-grip strength). [10] Epidemiological studies based on physical activity and physical fitness over CVD risk factors are too less in India. To the best of our knowledge, there is no longitudinal study from India that sees the combined physical activity, physical fitness and sedentary behaviors on CVD risk factors in urban population. There are several unanswered questions likehow much is the dose of physical activity for Indians? Indian specific practices like yoga does have productive role on CVD risk factors or not? If yes, what is the minimal dose of yoga and in which form?Indians are considered less fit as it is evident from Olympic and Asiad medal tally.So how much fitness is required by Indians to be prevented from CVD risk factors? Apart from these questions, Will all these four factors really prevent CVD risk factors in urban Indians or not? To answer these questions we decided to form a cohort with following objectives.
