Brief Summary:
This study investigates the effect that performing a cardiovascular maximum effort test (the Bruce treadmill protocol) has on performance of the Forward-Step-Down Test (FSDT). The FSDT is performed prior to the fatigue protocol as a baseline measurement, then at 1, 5, and 10 minutes after the fatigue protocol. Participants much reach a certain heart rate (within 10 bpm) of their age predicted maximum heart rate to ensure that the fatigue protocol reaches a maximum fatiguing effort.

Arm Intervention/treatment
Experimental: Pre/Post Repeated Measures
Performance on the forward-step-down test (FSDT) before and at one, five, and ten minutes following the Bruce Fatigue Protocol
Other: Bruce Fatigue Protocol
Participant will perform the Bruce protocol as a fatigue stimulus to examine the impact of fatigue on the FSDT




Primary Outcome Measures :
  1. Change in Score on the Forward-Step-Down Test [ Time Frame: up to 10 minutes after intervention ]
    The participants' scores on the pre-test FSDT will be compared to their scores post-test measured at 1, 5, and 10 minutes after the fatigue stimulus

Criteria

Inclusion Criteria:

  • Participants will be recruited from current physical therapy students in the class of 2020 who are enrolled in PHTH 7565. During the consent process, the participants will be screened using the American College of Sports Medicine's guidelines for safe participation in vigorous exercise. By meeting the ACSM criteria, the participant is considered low risk for adverse events while participating in vigorous activity. Finally, in order for the student to participate, they must achieve within 10 bpm of their predicted maximum heart rate, as calculated by the Tanaka formula as stated above.

Exclusion Criteria:

  • 3.2 Exclusion criteria are pre-existing cardiovascular conditions or diseases that prevent participation in a maximal effort test without physician clearance per the ACSM guidelines. Participants who do not reach their calculated target heart rate by the end of the Bruce protocol will be withdrawn from the study and will not complete post-fatigue testing.
