Summary

In August of 2019 a Canadian company, Form Athletica Inc. (FORM), introduced a pair of Smart swimming goggles (FORM goggles) with a built-in see-through display. The FORM Smart Swim Goggles both track and display the following performance metrics in real time: lap time splits, distance, stroke rate, stroke count, distance per stroke, pace, auto-rest, and heart rate. The goggles are also capable of showing structured workouts from inside the goggles. To assess the FORM goggles heart rate monitor, swimmer workout compliance, and swimmer performance adaptations, a group of recreational swimmers will complete familiarization sessions using the FORM goggles, perform a baseline performance test, follow a 12-week training program, and complete a final performance test.

Detailed description

The following research questions guide the study design: 1. Do recreational swimmers exhibit greater workout adherence when utilizing FORM goggles for real-time visual feedback in comparison to recreational swimmers who do not utilize such feedback? 2. Will the utilization of real-time visual feedback lead to higher motivation levels for recreational swimmers in comparison to recreational swimmers who do not utilize such real-time feedback? 3. Will there be a more pronounced performance enhancement among recreational swimmers who employ real-time visual feedback during a 12-week training period, as opposed to recreational swimmers who do not utilize such feedback? The experiment will be conducted over 13 weeks. Week 1 and the final day of week 13 will be in-person. The remaining weeks/days will be completed by the participants on their own. The in-person days will be carried out in a designated 25-meter indoor swimming pool using 6 lanes with a total of 12 swimmers per session. Video footage will be captured on all in-person days as a reference for any discrepancies in the FORM goggles output, and as a more precise method of measuring the performance test. FORM goggles will be used by all participants. Prior to Week 1, educational material and the Get Active Questionnaire will be provided to participants. The educational material will include information on standard swimming workout language, session rating of perceived exertion (sRPE), using the FORM goggles, and using the FORM Swim application on a cellular phone. The Get Active Questionnaire will need to be completed prior to commencing testing. Week 1 sessions will be utilized for familiarization/testing purposes and for recording data for the heart rate validation component of the study. Within each session, all participants will be equipped with an external heart rate monitor (Polar Verity) and 4 will be equipped with an additional heart rate monitor (Garmin HRM-Swim). Two sessions will be designated for the participants to get accustomed to the FORM goggles (face fit, field of view, and user interface). These sessions will consist of standardized workouts between 1000m and 2000m. The remaining session will be used to complete a performance test as described in the paragraph below. Before the data collection commences the following will occur: * Establishing the participants' understanding of the educational material distributed prior to week 1 * Retrieval of completed Get Active Questionnaires * Briefing the participants on using the FORM goggles and FORM app by the research personnel Week 1 will contain a baseline performance test. This performance test will determine the participants' critical swim speed (CSS) through two maximal efforts (400 m front crawl, followed by 50 m front crawl) with adequate rest between to produce "best-effort" swims. At the end of week 1, participants will be stratified and randomized into an intervention group ("feedback") and control group ("non-feedback") and reported using the CONSORT guidelines. "Feedback" will differ from "non-feedback" in that they will have the FORM goggles display on and receive real-time metrics and guided workouts throughout the remainder of the study. "non-feedback" will have the display turned on but will only have the workout timer visible during rest. Each group will be provided with the same twelve-week training program. Within each group there will be three training plan volumes (High, Medium, Low) that participants will be assigned to, ensuring appropriate training load prescription per participant. A swim coach will make the assignments using information from the participants' previous swimming experience, and the participants' baseline CSS. "Feedback" will have the convenience of guided workouts in the FORM goggles, while "non-feedback" will be required to use other methods of remembering their workouts (i.e., paper, standard training application, etc.). Weeks 2-13 will consist of unsupervised sessions to assess the impact of motivation, compliance and workout adherence on CSS performance. The participants will complete three workouts per week on their own time at their local indoor pool. Week 13 will conclude with a final CSS performance test on the final workout day. Workout instructions will be provided via email and in-app to all participants at the beginning of each training week. A questionnaire will be delivered to each participant after each training session to record data such as their perceived effort of the training session, exercise motivation, and exercise enjoyment. An additional questionnaire will be provided every 4 weeks to assess participants' experience with the usability and legibility of the FORM goggles or other utilized workout instruction/performance feedback device.
