Reserves, Injury Severity, and Outcomes in Traumatic Brain Injury: A CENTER‐TBI Observational Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Reserve refers to the brain's ability to maintain function after an injury and strongly relates to traumatic brain injury (TBI) outcomes. This study examined (1) whether associations between pre‐injury reserve proxies and outcomes differed across injury severity categories, and (2) whether the impact of injury severity varied across ...

Effects of caffeine on rate of force development: A meta‐analysis

Scandinavian Journal of Medicine & Science in Sports, 2021
This review aimed to conduct a meta‐analysis of studies examining the effects of caffeine on rate of force development (RFD). Ten databases were searched to find relevant studies. Risk of bias (RoB) of the included studies was evaluated. Data were analyzed in a random‐effects meta‐analysis.

Neuromechanics of the Rate of Force Development

Exercise and Sport Sciences Reviews, 2022
The rate at which an individual can develop force during rapid voluntary contractions can be influenced by both the neural drive to a muscle and its intrinsic musculotendinous properties. We hypothesize that the maximal rate of force development across human individuals is mainly attributable to the rate of motor unit recruitment.

Rate of force development as a measure of muscle damage

Scandinavian Journal of Medicine & Science in Sports, 2014
This study tested the hypothesis that rate of force development (RFD) would be a more sensitive indirect marker of muscle damage than maximum voluntary isometric contraction (MVC) peak torque. Ten men performed one concentric cycling and two eccentric cycling (ECC1, ECC2) bouts for 30 min at 60% of maximal concentric power output with 2 weeks between ...

Sports-Related Motor Processing at Different Rates of Force Development

Journal of Motor Behavior, 2022
How does our brain manage to process vast quantities of sensory information that define movement performance? By extracting the required movement parameters for which brain dynamics are, inter alia, assumed to be functionally related to, we used electroencephalography to investigate motor-related brain oscillations.

Maximal voluntary force and rate of force development in humans - importance of instruction

European Journal of Applied Physiology, 2001
The present investigation has been designed to confirm the effect of instruction (hard-and-fast instruction compared to fast instruction) upon maximal voluntary isometric force (MVF) and maximal rate of force development (MRFD) in muscle groups which differ with regards to muscle mass and usage.

EFFECT OF POTENTIATION AND STRETCHING ON MAXIMAL FORCE,RATE OF FORCE DEVELOPMENT, AND RANGE OF MOTION

Journal of Strength and Conditioning Research, 2005
The purpose of this investigation was to compare the effects of stretching vs. potentiation on subsequent maximal force and rate of force development capabilities of subjects in an isometric squat. Ten male collegiate athletes participated as subjects in this study.

Effects of Rate of Force Development on EMG Amplitude and Frequency

International Journal of Sports Medicine, 2005
The purpose of this study was to compare the amplitude and frequency of the gastrocnemius EMG during ramp and ballistic contractions in highly trained sprint athletes. Sixteen female sprinters performed ramp and ballistic isometric contractions on a Biodex dynamometer.

Analysis of Rate of Force Development as a Vertical Jump Height Predictor

Research Quarterly for Exercise and Sport, 2022
Purpose: Many researchers and coaches hold that the ability to generate force rapidly is an important factor in athletic performance. This concept is often studied by analyzing the rate of ground reaction force development (RFD) during vertical jumps; however, many such studies disagree on whether estimates of RFD are true predictors of vertical jump ...

Neuromuscular rate of force development deficit in Parkinson disease

Clinical Biomechanics, 2017
Bradykinesia and reduced neuromuscular force exist in Parkinson disease. The interpolated twitch technique has been used to evaluate central versus peripheral manifestations of neuromuscular strength in healthy, aging, and athletic populations, as well as moderate to advanced Parkinson disease, but this method has not been used in mild Parkinson ...
