An examination of agonist and antagonist motor unit firing properties
(2013)The interactions between opposing muscle (i.e. agonist and antagonist) groups can be extremely complex, task-dependent, and are still poorly understood. To identify possible origins of the coordination between antagonistic ... -
Bilateral Fatigue of the Anterior Tibialis in Individuals with Multiple Sclerosis
(2017-08)Multiple sclerosis (MS) is one of the most common progressive neurological diseases in young adults and is characterized by neurologic disruption within the central nervous system. Fatigue has been reported as one of the ... -
Effects of a functional fatigue protocol on maximal softball hitting.
(2010)Fatigue can affect athletic performance in many ways, including a decrease in sport specific accuracy, impairments in joint angles, and a decrease in overall muscle performance. In regards to fatigue, little research has ... -
THE EFFECTS OF MUSCLE LENGTH ON FORCE STEADINESS AND EMG RESPONSES FOLLOWING A FATIGUING PROTOCOL
(2017-05-12)The purpose of this study was to examine the effect of muscle length on force steadiness and EMG responses following a fatiguing intervention. Twenty-three subjects, fifteen men and eight women, were required to perform ... -
Effects of rest period length on exercise volume in older adults.
(2014)Research involving rest periods during resistance training for older adults is limited. Understanding optimal rest periods can help exercise professionals develop efficient and effective training programs for older adults. ... -
The effects of training status and recovery time on the reconstitution of impulse above electrically stimulated critical torque
(2022-05-13)Fatigue represents a reduction in the desired or expected muscular force (Porter, 1981) often as a result of intense or prolonged exercise. Critical power (CP) provides a framework to understand fatigue and exercise ... -
Electromyographic, mechanomyographic, and peak torque responses during repeated concentric isokinetic muscle actions with eyes-open versus eyes-closed
(2012)The purpose of this study was to compare the peak torque and electromyographic (EMG) and mechanomyographic (MMG) amplitude and mean frequency (MNF) responses during fatiguing isokinetic muscle actions for eyes-open versus ... -
Estimation of Critical Torque Using Neuromuscular Electrical Stimulation of the Quadriceps in Humans
(2017-05-12)Critical torque (CT) is an integrative measure/concept that represents the “critical” or upper boundary of steady-state work that can be performed without leading to exhaustive fatigue. While this concept has been observed ... -
Experimental study of two prestressed steel beam-concrete slab bridge units (FHWA-OK-6)
(1986-8)The behavior of two 55 ft. long prestressed, composite steel beam concrete slab bridge units was studied. The type of unit tested is currently used in county road bridge construction, where the use of prefabricated units ... -
Experimental study of two prestressed steel beam-concrete slab bridge units (FHWA-OK-87-1)
(1987-5)The behavior of two 55 ft. long prestressed, composite steel beamconcrete slab bridge units was studied. The type of unit tested is currently used in county road bridge construction, where the use of prefabricated units ... -
Fatigue Assessment of Bridge Members Based on In-Service Stresses interim report no. 1 August 1996 (FHWA-OK-95-07) 2196
(1996-8)Construction problems involving poor welding practice occurred during widening of the U.S. 69 bridge over the South Canadian River. As a result of these problems, cc>ncerns developed regarding the remaining fatigue life ... -
Fatigue damage to steel bridge diaphragms (FHWA-OK-89-10) 2156
(1989-12)The cause of diaphragm cracking on an interstate highway bridge was investigated. The investigation consisted of load-testing the bridge, performing a computeraided analysis of the bridge superstructure and specific ... -
Fatigue Performance of Asphalt Pavements Containing RAS and RAP
(Oklahoma City, OK : Oklahoma Department of Transportation, 2015., 2015-01)Rising oil and gas prices spurs development of methods and technologies for reducing fuel consumption and increased use of recycled materials. With increased environmental awareness, using reclaimed asphalt pavement (RAP) ... -
Field Performance Monitoring and Modeling of Instrumented Pavement on I-35 in McClain County
(Oklahoma City, OK : Oklahoma Department of Transportation, 2014., 2015-04)Phase 1 of this project was conducted to better understand the cause of pavement failure under actual traffic loading and environmental conditions. A 1,000-ft. long experimental pavement section was constructed on I-35 in ... -
Field performance monitoring and modeling of instrumented pavement on I-35 in McClain county - phase I
(2013-6)Flexible pavements comprise about 93 percent of paved roads in the United States. Although flexible pavements are widely used for reasons such as cost, constructability and consistent performance, they are often subject ... -
Impact of loaded trucks on highway infrastructure deterioration
(January, 1)Impact of loaded trucks on our transponation infrastructure system is becoming a growing concern for many State Departments of Transportation (DOTs) in the U.S. An increasing volume of loaded trucks due to the implememation ... -
Menstrual cycle effects on exercise-induced fatigability
(2020-06-26)Estrogen and progesterone have distinct concentrations across the menstrual cycle, each one promoting several physiological alterations other than preparing the uterus for pregnancy. Whether these physiological alterations ... -
Monitoring External Training Loads and Neuromuscular Performance for Division I Basketball Players over the Preseason
(2020-02-24)Limited research has paralleled concomitant changes in external training load (eTL) and countermovement jump (CMJ) performance. Therefore, this investigation characterized eTL and CMJ performance changes across preseason ... -
