Discussion: The purpose of this experiment was to examine the amount of work produced during intermittent exercise and continuous exercise. In addition, the physiological variables associated with muscular fatigue were also investigated. It was hypothesized that intermittent exercise would have a greater total work production over continuous exercise. According to the data, the alternate hypotheses stated above will have to be rejected, as there was no statistically significant difference among the intermittent and continuous exercise groups. This conclusion can be based on the analysis of raw data; however, more importantly the calculated p-value associated with total mean work was 0.15. For this experiment, a significance value of 5% or 0.05 was chosen. The calculated p-value of 0.15 is greater than 0.05; thus, we must accept that there is no statistically significant difference between the two groups tested, and the null hypothesis cannot be rejected. The mean values associated with both continuous and intermittent exercise are paired with extremely large standard deviations; these values are owed to the extreme variance among the individuals in the data set. The major findings of this experiment do not coincide with other research in this field. According to a study conducted by Grossl, Dantas de Lucas, Mendes de Souza and Guglielmo, it was found that intermittent exercise had a 24% greater time to fatigue when compare with continuous exercise (2012). Grossl et al. found that this was owed to physiological variables associated with muscle fatigue—namely blood lactate levels—were significantly lower in intermittent training versus the levels in continuous training. The researchers also added that heart rate readings were sligh... ... middle of paper ... ...ow the importance psychological factors influence how an individual responds to exercise intensity, whether it be in intervals or on a continuous basis. Other factors that may have contributed to the observed differences are the time periods between bouts of testing intervals. Although 20 minutes allows for some recovery and lowering of the heart rate, testing on separate days may be a more effective approach to rule out this variable. The subjects may have tired themselves out in the first round of testing, which may have lead to some discrepancies in the data collected. Testing of blood lactate levels between the resting periods may also help indicate the level of fatigue an individual is experience as those readings are indicative of muscle fatigue. Before commencing the next round of testing it should be ensured that the subject is full rested and well hydrated.
