Investigation of the Virtual Physiology of Exercise Laboratory

The Virtual Physiology of Exercise Laboratory (VPEL) replicates the test construction, data collection and analysis phases of several common “hands on” exercise physiology lab (HOEPL) experiences. The VPEL includes four modules: 1) Cardiovascular, 2) VO2 max, 3) Lactate and Ventilatory Thresholds and 4) Respiratory Exchange Ratio. This investigation sought to compare student learning from both HOEPL and VPEL activities. Students from the spring 2009 Integrated Fitness Programming course were randomly assigned to investigational group 1 or 2. Group 1 completed a HOEPL version of a VO2 max lab activity, whereas group 2 completed the VPEL VO2 Max Module. Both groups then took the same exam to assess their understanding of VO2 max lab concepts. Group 2 then completed the HOEPL version of a lactate and ventilatory thresholds lab activity, whereas group 1 completed the VPEL Lactate and Ventilatory Thresholds Module. Both groups then took the same exam to evaluate their understanding of lactate and ventilatory threshold lab concepts. Mean VO2 max exam scores were 86.39[plusmn]4.13 and 85.64[plusmn]6.72, and mean lactate and ventilatory thresholds exam scores were 85.50[plusmn]8.05 and 86.15[plusmn]6.45, for groups 1 and 2, respectively. There were no statistical differences between the two groups on either exam. This study provides evidence that students learned equally well from the HOEPL and VPEL activities.
