Background: For many ailments, exercise has become a popular therapeutic choice. Rehab through exercise is frequently utilised to improve respiratory and cardiovascular conditions. Despite the numerous benefits of regular exercise, persons with sedentary lifestyles, particularly students, do not include exercise into their daily routines. Exercise has different effects on the cardiovascular and respiratory systems depending on health and disease. Its effects vary depending on the physical fitness of the individuals, even in healthy individuals.
Aim and Objectives: The purpose of this study was to determine the effect that short-term exercise has on cardiorespiratory parameters in young healthy people who have and have not been exercising regularly.
Methods: For the purpose of the study, there were collected fifty medical students between the ages of 18 and 25 who had never participated in regular physical activity. Group I consisted of 25 students who engaged in activities such as cycling, aerobics, and yoga for a total of three months, each day for a duration of twenty-five minutes. Group II consisted of 25 students who did not take part in any form of physical activity or exercise. Before and immediately after a short-term exercise consisting of cycling for six minutes, the heart rate and blood pressure of the participants were recorded. Tests of the pulmonary function were performed in a comparable fashion both before and two minutes after the exercise.
Results: There was no discernible difference between persons who had exercise training and those who had not in terms of their HR, SBP, DBP, PP, MAP, or RPP. In trained people, the PFT metrics SVC, PEF and MVV were considerably higher (p=0.01, 0.03 and 0.03 respectively). When the effects of short-term exercise were compared, it was found that HR, SBP, PP, MAP and RPP all increased considerably after exercise in both groups (p value 0.05). This was the case regardless of whether the exercise was aerobic or anaerobic. Untrained participants showed a substantial drop in their PEF following exercise (p=0.05), whereas trained persons did not demonstrate the same trend (p=0.05).
Conclusion: Exercise performed for a shorter period of time does not have a substantial impact on the respiratory parameters of those who are not exercise trained. A training programme consisting of three months' worth of exercise can improve respiratory function with almost little effect on cardiovascular function.
