The aim of this study was to use heart rate to predict workload during soccer. The results of the study in relation to the aim and hypothesis were correct. The soccer data, which is the percent of VO2 max per heart rate, was equivalent to the treadmill data. I would suggest that one can use HR to estimate the percentage of VO2 max. Some limitations in using heart rate to predict equivalent VO2 values during intermittent sports such as soccer are: indoor versus outdoor soccer, stress of the game, environmental conditions and mitochondrial activity levels. They found a difference of about 25% between estimated and measured VO2 and concluded that the discrepancy was mainly due to the different VO2 response during intermittent soccer activities compared to the steady-state laboratory test (Esposito et al, 2004). Interval running found in sports such as soccer and constant-rate running such as distance running, consume similar amounts of oxygen when performed at near max sustained speed (Pratt, Brendan, and Clark, 2013). For this reason it is as likely to be accurate in estimating VO2 values as continuous exercise protocols.…show more content…
The analysis of the data collected from the soccer game gives us an accurate estimate of what physiological workload level the subject is at any given heart rate. Due to the fact that soccer involves a little of anaerobic and aerobic the subjects heart rate kept on going up and down all the time. This is why comparisons of the percentage of VO2 max during the time spent playing outfield compared to goal keeper changed accordingly with the change in heart rate. Also during the soccer game the subject did not go to maximal exertion as he did during the treadmill
