Elastic Resistance Effectiveness On Increasing Strength Of Shoulders And Hips, Kelsey J. Picha, Muataz R. Almaddah, Jordan Barker, Tavis Ciochetty, W. Scott Black, Timothy L. Uhl

Physical Therapy Faculty Publications

Elastic resistance is a common training method used to gain strength. Currently, progression with elastic resistance is based on the perceived exertion of the exercise or completion of targeted repetitions; exact resistance is typically unknown. This study's objective is to determine if knowledge of load during elastic resistance exercise will increase strength gains during exercises. Participants were randomized into two strength training groups, elastic resistance only and elastic resistance using a load cell (LC) that displays force during exercise. The LC group used a Smart Handle (Patterson Medical Supply, Chicago, IL) to complete all exercises. Each participant completed the same …

Calculation Of Resistive Loads For Elastic Resistive Exercises, Kelsey J. Picha, Timothy L. Uhl

Physical Therapy Faculty Publications

Context:

What is the correct resistive load to start resistive training with elastic resistance to gain strength? This question is typically answered by the clinician's best estimate and patient's level of discomfort without objective evidence.

Objective:

To determine the average level of resistance to initiate a strengthening routine with elastic resistance following isometric strength testing.

Design:

Cohort.

Setting:

Clinical.

Participants:

Thirty-four subjects (31±13yrs, 73±17kg, 170±12cm).

Interventions:

The force produced was measured in Newtons (N) with an isometric dynamometer. The force distance was the distance from center of joint to location of force applied was measured in meters to calculate torque …

Comparison Of Isokinetic Hip Abduction And Adduction Peak Torques And Ratio Between Sexes, Dai Sugimoto, Carl G. Mattacola, David R. Mullineaux, Thomas Gerard Palmer, Timothy E. Hewett

Physical Therapy Faculty Publications

OBJECTIVE: To evaluate hip abductor and adductor peak torque outputs and compare their ratios between sexes.

DESIGN: A cross-sectional laboratory-controlled study.

SETTING: Participants visited a laboratory and performed an isokinetic hip abductor and adductor test. All participants performed 2 sets of 5 repetitions of concentric hip abduction and adduction in a standing position at 60 degrees per second. Gravity was determined as a function of joint angle relative to the horizontal plane and was corrected by normalizing the weight of the limb on an individual basis.

PARTICIPANTS: A total of 36 collegiate athletes.

INDEPENDENT VARIABLES: Sex (20 females and 16 …
