Description
Introduction: Stress has been greatly associated with decreased sports performance. In the long term, it has been shown that stress could decrease muscular strength gains, hinder muscle growth, cause muscle atrophy, and increase the risk of injury. In the short term, stress as in a mental grabbing task was associated with decreased muscular endurance, velocity, and performance in general. However, acute stress and its relationship with power, is still unknown. We hypothesized that when participants experience an acutely-induced stress, they would have decreased lower extremity power than those who did not experience an acute stressor. Methods: Approximately twenty to forty students will participate in this study. To start, a consent form and a questionnaire will be handed out to the participants. Following, a warm up protocol will be conducted by the researcher, then a jumping familiarization session will take place. After that, Participants will be asked to complete a baseline jumping test composed of four jumping tests on the VALD SmartJump Mat which is going to measure the lower extremity power for the participants. Afterwards, the participants will be randomly assigned to a control group or a stress group and depending on that, they will be asked to complete a task through a virtual reality headset. Participants in control group are going to watch Youtube video showing elephant walking in their natural habitat through the headset. Participants in the stress group are going to undergo the TSST test through the headset, which is basically a virtual interview. Then, participants will be asked to complete the same four jumping tests as before. Results: Data analysis is anticipated to be complete by the second week of April. This study has been approved by the IRB, Study number IRB-FY23-24-3338.
