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.

Conditions

Fatigue

Keywords

muscle performance; injury prevention; step down; fatigue

Outcome Measures

Primary Outcomes (1)

• Change in Score on the Forward-Step-Down Test

  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

  up to 10 minutes after intervention

Study Arms (1)

Pre/Post Repeated Measures

EXPERIMENTAL

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

Interventions

Bruce Fatigue Protocol OTHER

Participant will perform the Bruce protocol as a fatigue stimulus to examine the impact of fatigue on the FSDT

Pre/Post Repeated Measures

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• 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.
