Exercise Science and Sport Management (Gerald Mangine and James Henley)
Agreement Between Methods for Describing the Intensity of a High-Intensity Functional Training Workout
-
The purpose of this study is to examine the agreement between velocity-based descriptors of high-intensity functional training workout intensity, more traditional descriptors of exercise intensity (e.g., percentage of max strength), and commonly accepted metrics of HIFT intensity (e.g., lactate, HR, and RPE). For this study, participants will be asked to report to the Human Performance Laboratory (HPL; Room 1104 in Prillaman Hall on the 快猫成版视频 Main Campus) on three separate occasions wearing athletic clothing. The first baseline visit will be used to quantify relevant physical and physiological attributes by assessing body composition (via 4-compartment model) and performance in workout-relevant exercises (i.e., power clean, toes-to-bar, and wall ball shots). The first experimental visit will begin within 48 鈥 72 hours of the baseline visit, and the second experimental visit can begin within 48 鈥 72 hours of the first experimental session. All visits for this study will be completed within 14 days of enrollment, and always at a time that is consistent with the participant's normal training schedule. Experimental visits will begin with a heart rate variability assessment, followed by a subjective rating of effort, and then a blood sample donation for lactate concentration analysis. Participants will then initiate a standard warm-up that will conclude with maximal speed assessments, followed by a 5-minute rest break, and then completion of either a lesser- (LV-WOD) or higher-volume (HV-WOD) workout consisting of barbell power cleans (5 or 10 repetitions), toes-to-bar (10 or 15 repetitions), and WB (15 or 20 repetitions). All pre-exercise assessments, except for maximal velocity assessments, will be repeated immediately following completion of the workout. Workout order will be randomly assigned by the research team prior to the second visit with participants being notified of the order at the beginning of the warm-up period on that visit. They will complete the remaining workout on their third visit.
Changes in speed (i.e., repetition completion rate) for each exercise will be monitored
and recorded during both experimental workout conditions, and then be calculated as
a percentage of the participants' established maximal speed. Relationships and agreement
between their percentage speed and established metrics of intensity will then be statistically
examined.

At the end of the project, students should be able to:
- Define the terminology associated with research and theory in their field
- Articulate how their research study contributes to their academic field
- Collect data for a research study
- Analyze, synthesize, organize, and interpret data from their research study
- Work effectively as part of a team
- Present their research/creative activity to an audience (e.g., poster, oral presentation,
performance, display)
- Articulate the ways in which their research participation helps prepare them for graduate
school and/or a career
- Describe appropriate professional conduct (e.g., at conferences, when interacting
with professionals in the field)
- Reflect on their research project, including strengths, weaknesses, and things they
would do differently in another research context
- Time management
- Self-confidence/self-esteem
- Organizational skills
- Persistence on tasks

As a first-year undergraduate researcher, you will be asked to support the existing
research team (older undergraduate students, graduate students, and faculty researchers).
These will mainly include assisting existing research team members with setting up
and calibrating equipment, recording information on data collection sheets, and guiding
participants through baseline and experimental visits (e.g., taking them through the
warm-up, reminding which assessments are next, confirming subsequent visits, etc.).
As you demonstrate comfort with study operations, you will be given opportunities
to assume a more active role (e.g., operate study equipment).
Once the study begins, all study visits will occur during a time that is consistent
with the participant's normal training schedule, and ideally, they will complete all
three study visits within the same week. However, we will typically avoid Tuesdays
and Thursdays due to heavy utilization of our research laboratory for classes. If
visits do occur on Tuesdays or Thursdays, they will take place either early morning
(before 8:00 am) or after 5:00 pm. Outside of baseline or experimental visits, you
will assist by digitally recording hand-written data collection sheets and organizing
participant data folders (physical and electronic). You may complete these duties
whenever your schedule permits and we are not actively collecting participant data.
