Physiological Rate of Recovery in Relation to Activity Level

Abstract

The importance of physical activity is frequently mentioned in regards to improved health and disease prevention; however, how often should one exercise and what type of exercise is most beneficial? Previous studies have established that post exercise recovery rate is indicative of current physical fitness and future health risks. In this study, the effect frequency and type of exercise on post exercise recovery rate are further examined within a healthy college student population. It was hypothesized that individuals who exercised 4-5 times a week would have the most efficient recovery times when measured by percent change in heart rate, blood pressure, and respiratory rate. Participants biked at a moderate pace on a stationary bike for three minutes and their blood pressure, heart rate, and respiratory rate were collected and recorded post exercise. An ANOVA was used to compare the deviation from baseline for each participant. Heart rate and respiratory rate showed a statistically significant change in participants, specifically those who exercise greater than three times a week and participate in both aerobic and anaerobic exercise had the most efficient recovery rate. Though the results of pulse pressure were statistically significant, it was determined that the trends displayed were inconclusive. Due to the significance of our data the null hypothesis was rejected. Overall the study showed that physiologically, physical activity is most beneficial to individuals when a combination of anaerobic and aerobic exercise is integrated into their workout regime for those who exercise more than three days per week.
