The use of virtual reality (VR) in the clinical setting has increased substantially in recent years. 1 It has been established as an efficacious tool for balance and gait rehabilitation in neurological patients and provides improved benefits when combined with conventional rehabilitation. 2 A

VTC provides an estimate of how long it would take an individual to lose

Alternatively, augmented reality, virtual reality, and video-game-based training are available ( de Bruin, Schoene, Pichierri, & Smith, 2010 ; Duque et al., 2013 ). In particular, previous studies have

Virtual environments with real-time feedback can simulate extrinsic goals that mimic real life conditions. The purpose was to compare jump performance and biomechanics with a physical overhead goal (POG) and with a virtual overhead goal (VOG). Fourteen female subjects participated (age: 18.8 ± 1.1 years, height: 163.2 ± 8.1 cm, weight 63.0 ± 7.9 kg). Sagittal plane trunk, hip, and knee biomechanics were calculated during the landing and take-off phases of drop vertical jump with different goal conditions. Repeated-measures ANOVAs determined differences between goal conditions. Vertical jump height displacement was not different during VOG compared with POG. Greater hip extensor moment (P < .001*) and hip angular impulse (P < .004*) were found during VOG compared with POG. Subjects landed more erect with less magnitude of trunk flexion (P = .002*) during POG compared with VOG. A virtual target can optimize jump height and promote increased hip moments and trunk flexion. This may be a useful alternative to physical targets to improve performance during certain biomechanical testing, screening, and training conditions.

Grounded in social facilitation theory, this study compared the impact on exercise intensity of a virtual versus a live competitor, when riding a virtual reality-enhanced stationary bike (“cybercycle”). It was hypothesized that competitiveness would moderate effects. Twenty-three female college students were exposed to three conditions on a cybercycle: solo training, virtual competitor, and live competitor. After training without a competitor (solo condition for familiarization with equipment), participants competed against a virtual avatar or live rider (random order of presentation). A repeated-measures analysis revealed a significant condition (virtual/live) by competitiveness (high/low) interaction for exercise intensity (watts). More competitive participants exhibited significantly greater exercise intensity when competing against a live versus virtual competitor. The implication is that live competitors can have an added social facilitation effect and influence exercise intensity, although competitiveness moderates this effect.

At many institutions introductory exercise physiology courses are required for all kinesiology students. The laboratory portion of these courses usually involves development of knowledge, skills, and abilities (KSAs) connected with content presented in lecture. Due to scalability issues, the Kinesiology Department at California State University Monterey Bay cannot offer traditional laboratory experiences. Therefore, online and hybrid laboratory experiences were created to provide similar opportunities for students, address scalability issues, and enhance student engagement and learning. Creation of these carefully crafted laboratory experiences allowed instructors to (a) highlight and explain key foundational principles, (b) provide experiences involving practical application of material presented in lecture, and (c) present students with additional learning experiences while maintaining high learner expectations. The following article outlines the process used to create these virtual laboratory experiences for students in an undergraduate introductory exercise physiology course.
