A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Shawn Dockter Jan 1999

A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Shawn Dockter

Physical Therapy Scholarly Projects

The purpose of this study was to compare maximal quadriceps torque production between morning (AM) and afternoon (PM) hours. Thirty healthy male subjects between the ages of 21 and 43 were tested during an AM and PM session on the Kin-Com dynamometer. Six concentric isokinetic contractions of the right quadriceps were tested at a speed of 60° Is. The maximal peak torque measurements were compared between the AM and PM sessions to establish the validity of results taken at differing times of day. No significant difference in strength assessment due to time of day was found. The data collected in …


A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Shawn Mccoul Jan 1999

A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Shawn Mccoul

Physical Therapy Scholarly Projects

The purpose of this study was to compare maximal quadriceps torque production in early morning hours to afternoon hours. Thirty male subjects volunteered to participate in this study and were randomly assigned to an AM or PM testing session. At least one week after the first test, the subjects completed a similar test in the opposite time slot. Each subject was positioned on the Kin-Com (Chattecx Corp., Chattanooga, 'IN) dynamometer and performed six maximal concentric isokinetic repetitions of knee extension at 600/s between the ROM of 10° and 80° of knee flexion. The AM/PM ratios indicated no significant difference between …


A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Michael Rexin Jan 1999

A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Michael Rexin

Physical Therapy Scholarly Projects

The purpose of this study is to compare maximal quadriceps peak torque production in isokinetic strength assessment in the morning and the afternoon. Thn1y male subjects between the ages of21 and 43 volunteered for this study. The subjects were randomly assigned to either an early morning group (7:30 AM to 9 AM) or an afternoon group (2:30 PM to 5 PM). Each subject performed six maximal concentric isokinetic contractions with the quadriceps muscles after a warm up and an initial familiarization session. Data analysis was done using a t-test for paired samples and Pearson's correlation The results showed a .90 …


A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Denise Willardsen Jan 1999

A Comparison Of The Maximal Torque Production Of The Quadriceps Muscle During Morning And Afternoon Strength Assessment, Denise Willardsen

Physical Therapy Scholarly Projects

The purpose of this study was to compare maximal quadriceps torque production in morning hours (AM) to maximal quadriceps torque production in afternoon hours (PM). Thirty healthy male subjects between the ages of 19 and 45 were tested during an AM and a PM session on the Kin-Com dynamometer. A trial of six concentric isokinetic contractions of the right quadriceps were tested at a speed of 60° Is. The maximal peak torque measurements were compared between the AM and the PM sessions to establish the accuracy of results taken at differing times of the day. No significant difference in strength …
