F1000Research
Background: Physical activity and fitness level of fitness decline mostly between adolescence and early adulthood. This leads to risks of non-communicable diseases in the future. Medical students, assumed to have an extensive understanding of physical exercise and its benefits, are less active than they were before attending graduate school. This study aimed to assess changes in physical fitness and physical activity of students over-time. Methods: This was a prospective study undertaken at Basic Science Complex of Kathmandu Medical College Teaching Hospital in Nepal. In total, 72 medical students were put through a modified Harvard step test during their first year and then three years later during their third year at medical school. Maximum aerobic capacity (VO2 max) was calculated subsequently by plotting the average pulse rate on the Astrand-Rhyming Nomogram. Results: The mean value of relative maximum aerobic capacity (VO2 max) decreased from first year to the third year. When ...

Background: Most often, it is of interest to know the individual's capacity for physical work. A reduction of this capacity might be the first sign of disease. Further, the lack of physical activity and sedentary lifestyles in the young generation particularly students have been a matter of concern in recent days. Cardiorespiratory fitness is one of the most important parameters of physical fitness and is assessed by cardiorespiratory efficiency tests. These tests include assessment of VO 2 Max, 40mm Hg Test, Breath Holding Test. Aim: To study the physical fitness of undergraduate medical students based on the assessment of cardiorespiratory efficiency tests in Sports Physiology Laboratory of MGIMS Methods: A total of 60 MBBS students (32 boys and 28 girls) of Mahatma Gandhi Institute of Medical Sciences, Sevagram, Wardha were included in the study from different levels of the course within the age group of 17-25 years. History was recorded followed by anthropometry and clinical...
Assessment of cardiovascular fitness [VO2 max] among medical students by Queens College step test
Objective: Cardio respiratory fitness in terms of maximum oxygen uptake [VO 2max ] reflects physical fitness of a person.VO 2max is single best measure of cardio respiratory capacity and is considered as a bench mark to quantify cardiovascular function capacity and aerobic fitness. The main aim of study was to assess and compare the cardio respiratory fitness in terms of maximum aerobic capacity [VO 2max ] among the young adult male and female medical students of Maharishi Markandeshwar University [MMU], Mullana, Haryana. Method: A total of fifty seven young adult male [n=30] and female [n=27] students, around age group of 18-24 years were recruited by simple random sampling from Maharishi Markandeshwar University, Haryana.VO 2max was estimated indirectly by following the protocol of Queen's College Step Test [QCT] method. QCT is the simplest one to determine cardio respiratory fitness in terms of maximum oxygen uptake. Result: In present study it was found that mean value of VO 2max for males was [45.66+8.96] ml/kg/min and for females it was [37.85+4.3] ml/kg/min. The mean value of VO 2max was found significantly higher in male as compared to female students [P value <0.0001]. Conclusion: From the study it was concluded that our subjects fitted in the category of fair on cardio respiratory fitness scale, could be because of the decreased physical activity, unhealthy lifestyle behaviors as are established during the years of gaining education, which may influence adult behavior and health status. Physical fitness performance was better in male students than female students. Health promotion policies and physical activity programs should be designed to improve cardio respiratory fitness.

Background: Cardio respiratory fitness is the ability of the cardiovascular and respiratory system to supply oxygen to the working muscle tissues and the ability of the muscles to utilize oxygen to produce energy. Maximal Oxygen uptake (VO2max) is the Gold standard to measure the cardio respiratory fitness. High fitness level lowers the risk of many health problems like cardiovascular diseases, Diabetes, Obesity etc. Hence it is required for students to measure and analyze their fitness for a healthy lifestyle. Objective: To determine the cardio respiratory fitness of MBBS students Materials and Methods: In this cross sectional study, 55 healthy volunteers (age 20-29 yrs) were recruited from among the MBBS students of RIMS, Imphal. Cardio respiratory fitness in terms of VO2max was assessed by the Bruce Protocol treadmill test. Results: The mean VO2 max was 41.3471±6.80 ml/kg/min. It was found that the mean VO2max of the students who exercise regularly (n=28;45.74±4.8ml/kg/min) was s...
Physical and Cardiorespiratory fitness of undergraduate male medical students
Objectives: 1) Assessment of physical fitness, Cardio-respiratory fitness 2) To assess the chances of developing obesity in medical students 3) If their fitness is already affected, suggest interventions to improve it & to prevent further harm. Methods: Present study was carried out in young apparently healthy 100 medical students (aged 18-22). We studied body mass index (BMI) and depending on it students were divided into 5 groups (Underweight, Normal, overweight, preobese and obese). Maximum aerobic power (VO2 max- measured from Queen’s College Step test), maximum anaerobic power (PAP- measured from vertical jump test), waist/hip ratio (W/H), trunk flexibility and mobility (assessed by modified sit & reach test), resting heart rate and blood pressure, skin fold thickness measured by varnier caliper and Peak expiratory flow rate (PEFR) were measured. Results were computed as mean and standard deviation. By applying one way ANOVA results were compared. Results: Compared to normal group underweight group had significant low values of waist circumference, hip girth, skin fold thickness and PAP. Overweight, Preobese and obese group had higher values of skin fold thickness, W/H ratio, resting heart rate, blood pressure and PAP. Whereas VO2 max was not significantly reduced probably due to smaller sample size of these groups compared to normal (50 % of total). Conclusions: Medical students have sedentary lifestyle and incidence of obesity is increasing (present study 38/100). Modification of sedentary life style and increasing physical activity will improve cardiorespiratory fitness of the medical students. Students were advised to do the required changes in their day to day activities.
