Summary

The purpose of this study will be to determine the effects of a 2-minute single limb lateral step-down fatigue test versus a 30 second side hop test on single limb forward hop distance.

Conditions

  • Healthy

Interventions

OTHER

Step-Down Test (2 min)

The 2-minute single limb lateral-step down test will be used to induce lower extremity muscle fatigue. Participants will be instructed to perform a single limb lateral step-down test on a 31 cm box (12-inches), touching their heel to the floor each time as many times as possible in 2 minutes. The number of lateral step-downs will be recorded.

OTHER

Side hop test (30 s)

The 30 second side hop test will be used to induce lower extremity muscle fatigue. Participants will be instructed to jump as many times as possible over two parallel strips of tape placed 40 cm apart, but must initiate approximately 30 degrees of knee flexion each jump. The number of successful jumps performed within 30 seconds will be recorded and used for data analysis. An unsuccessful jump will be defined as touching the tape or the area inside the tape. We will record the number of successful trials.
