Biomechanical And Proprioceptive Differences During Drop Landings Between Dancers And Non-Dancers, Katie E. Volkerding, Caroline J. Ketcham Ph.D. Oct 2013

Biomechanical And Proprioceptive Differences During Drop Landings Between Dancers And Non-Dancers, Katie E. Volkerding, Caroline J. Ketcham Ph.D.

International Journal of Exercise Science

International Journal of Exercise Science 6(4) : 289-299, 2013. The focus of this research was to determine if female dancers have differing kinematic and kinetic characteristics when landing from three heights (0.2, 0.5, and 0.8 m) both with and without vision compared to non-dancers. It was hypothesized that dancers would show differing kinematic and kinetic patterns of control due to their increased proprioceptive awareness. Eight collegiate dancers and seven collegiate controls who were neither dancers nor collegiate jumping athletes volunteered for this study. Sagittal plane lower limb joint angles were measured at 100 Hz prior to landing through stability with …


Activity-Specific Effects Of Fatigue Protocols May Influence Landing Kinematics: A Pilot Study, Adrian Chavez, Duane Knudson, Rod Harter, Kevin Mccurdy Jul 2013

Activity-Specific Effects Of Fatigue Protocols May Influence Landing Kinematics: A Pilot Study, Adrian Chavez, Duane Knudson, Rod Harter, Kevin Mccurdy

International Journal of Exercise Science

International Journal of Exercise Science 6(3) : 242-249, 2013. Fatigue is a common neuromuscular factor examined in relation to risk of ACL injury. Unfortunately, variations between the protocols used to induce fatigue in studies examining this phenomenon may have contributed to reported inconsistencies in the effects of fatigue on movements with high-risk of ACL injury. In addition, the ecological validity of fatigue experienced as a result of protocols commonly administered in the experimental setting is unclear. The purpose of this study was to examine the ecological validity, using basketball competition as the criterion measure, of two fatigue protocols commonly used …

Effects Of Foot Position During Squatting On The Quadriceps Femoris: An Electromyographic Study, Nicholas G. Murray, Daniel Cipriani, Denise O'Rand, Rebecca Reed-Jones Apr 2013

Effects Of Foot Position During Squatting On The Quadriceps Femoris: An Electromyographic Study, Nicholas G. Murray, Daniel Cipriani, Denise O'Rand, Rebecca Reed-Jones

International Journal of Exercise Science

International Journal of Exercise Science 6(2) : 114-125, 2013. Weightlifters have commonly believed that changing joint position can alter specific muscle activation. The magnitude of force produced by a muscle is highly dependent upon the length of the muscle. The purpose of this study was to determine the effect of foot positioning on muscle activation of the superficial quadriceps as measured by surface electromyography (sEMG) during a functional squatting movement in healthy adults. Twenty physically active asymptomatic adults (7 females and 13 males) were included in the study while four different foot positions (Neutral, Internally Rotated, Externally Rotated, and Staggered) …


Gender Comparisons Of The Electromyographic Responses To Knee Extension Exercises With Different Initial Restriction Pressures, Guillermo Perez B.S., Joe Angel Lopez B.S., Murat Karabulut Ph.D, Cscs Feb 2013

Gender Comparisons Of The Electromyographic Responses To Knee Extension Exercises With Different Initial Restriction Pressures, Guillermo Perez B.S., Joe Angel Lopez B.S., Murat Karabulut Ph.D, Cscs

International Journal of Exercise Science: Conference Proceedings

The effects of blood flow restriction training (BFR) may be impacted by the several physiological and biological differences found between genders. Since the pattern of regional body composition may be different between males and females, the impact of tightness of the restrictive cuffs (initial restrictive pressure; IRP) might be different for females causing variation in the level of muscle activation; therefore research on a female population is needed to have a complete understanding of BFR. PURPOSE: To compare changes in electromyography (EMG) amplitude (RMS) and median frequency (MDF) in males and females during application of different IRPs of 40-45 mmHg …
