Participants are needed for a research study conducted by Hannah Bradshaw in the Biomechanics Laboratory at Ball State University under the supervision of Dr. Clark Dickin.  This study has been approved by the BSU IRB (#2253520).

WHY:  To investigate the influence and reflexive nature of the inner ear during jumping and balance tasks. 

WHO:  Recreational or competitive athletes in ANY sport between the ages of 18-35 years, who engages in at least 150 minutes of moderate intensity aerobic exercise per week, or at least 75 minutes of vigorous intensity aerobic exercise per week.

  • You must be free from orthopedic or neurological conditions (including concussion) that would limit your ability to jump maximally, balance, or hop and land on one leg.
  • No previous ligament reconstruction on either leg, or current lower limb pain or injury that would prevent or limit testing.

WHAT:  You will be asked to come to the laboratory for TWO VISITS separated by one week.

  • You will be randomized into one of two groups, with each group performing different warm-ups.
  • You will then be asked to complete FIVE tasks: countermovement jump, single-leg hop to land, static balance test with the eyes both open and closed, and two tests for vestibular system function using a gyroscope.
  • Time commitment is approximately 90 minutes for each visit (total = ~3 hours).
  • You are required to wear compressive clothing during testing (provided by Ball State University Biomechanics Laboratory) and to perform all assessments barefoot.
  • You will be asked to complete a Health History and Physical Activity Questionnaire.
  • Participants who complete the study will be awarded a $20 Tango gift card.

WHERE:  Ball State University Biomechanics Laboratory (HP 309 & 311). Parking is available if you are coming from off-campus.
