Brief Summary

This pilot study will examine the effect of testing order on test outcomes for measures of strength, dynamic balance, and movement quality. Each participant will perform a baseline test, then will perform the 6 iterations of the testing sequence.

Outcome Measures

Primary Outcomes (5)

• Forward-Step-Down Test

  a step-down task that is performed off a 20 cm box. Five repetitions are performed to give one score (minimum score 0, maximum score 6). A higher score is worse.

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

• Firefighter Specific Functional Balance Test

  A dynamic balance test performed by stepping down from a 15cm box, walking across a low beam (4cm high), and stepping up onto a 10cm box, turning around, and returning to the original box. 8 Trials are performed. In 4 trials, a bar is placed at 75% of the participant's height for them to negotiate while on the beam. A faster time with fewer errors is better.

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

• Y-Balance Test

  A dynamic balance test that is performed on the dominant leg, reaching in the anterior, posteromedial, and posterolateral directions. The length of reach is standardized to participants' leg length. A higher score is better.

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

• Knee Extensor Isokinetic Test

  Knee extensor isokinetic strength will be tested at 60°, 180°, and 300° per second from the seated position with 5, 10, and 10 concentric contractions for each speed. A higher reading of strength is better.

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

• Hip Abductor Isokinetic Test

  Hip abductor strength will be tested at 30°, 60°, and 120° per second from the standing position. A higher reading of strength is better.

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

Secondary Outcomes (3)

• Rating of Fatigue

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

• Rating of Perceived Exertion

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.

• Heartrate

  This outcome will be assessed at each visit throughout the study, an average of 6 weeks.
