The ability to generate quick submaximal muscle forces followed by quick relaxations is essential for various athletic and daily tasks. While force generation has been studied extensively, the studies of force relaxation are scarce. Therefore, we aimed to develop the rate of force relaxation scaling factor (RFR-SF) as a kinetic variable to assess the ...

Methodological considerations in the calculation of the rate of force development scaling factor
Physiological Measurement, 2017Abstract Objective : Within this methodological study, we aimed to explore the effects of seven different commonly applied routines for rate of force development (RFD) calculation on the calculation of rate of force development scaling factor (RFD-SF) and r

Age-Related Decline in the Rate of Force Development Scaling Factor
Motor Control, 2013Physical quickness is less in older adults with implications for fall prevention, movement initiation, and activities of daily living. The purpose was to compare control of rapid contractions in young and older adults within two diverse muscle groups: powerful elbow extensors (EE) and dexterous index finger abductors (IFA). Most-rapid force pulses to a

Maturation in Rate of High-Velocity, Low-Amplitude Force Development
Journal of Manipulative and Physiological Therapeutics, 2011The purpose of this study was to examine the maturation of force development during a thoracic high-velocity, low-amplitude displacement procedure at stages throughout chiropractic education. The hypothesis posed a natural development in rate of force directly related to the duration of experience.

Unilateral arm strength training improves contralateral peak force and rate of force development
European Journal of Applied Physiology, 2008Neural adaptation following maximal strength training improves the ability to rapidly develop force. Unilateral strength training also leads to contralateral strength improvement, due to cross-over effects. However, adaptations in the rate of force development and peak force in the contralateral untrained arm after one-arm training have not been ...

The force generated during a maximal voluntary contraction (MVC) is known to increase by resistance training. Although this increase cannot be solely attributed to changes in the muscle itself, many studies examining muscle activation at peak force failed to detect neural adaptations with resistance training. However, the activation prior to peak force

Journal of Strength and Conditioning Research, 2007
Because the intensity of plyometric exercises usually is based simply upon anecdotal recommendations rather than empirical evidence, this study sought to quantify a variety of these exercises based on forces placed upon the knee. Six National Collegiate Athletic Association Division I athletes who routinely trained with plyometric exercises performed ...

Early and late rate of force development: differential adaptive responses to resistance training?
Scandinavian Journal of Medicine & Science in Sports, 2010The objective of this study is to investigate the potentially opposing influence of qualitative and quantitative muscular adaptations in response to high‐intensity resistance training on contractile rate of force development (RFD) in the early (<100 ms) and later phases (>200 ms) of rising muscle force. Fifteen healthy young males participated in

Maximum rate of force development is increased by antagonist conditioning contraction
Journal of Applied Physiology, 1994Nine subjects performed maximum contractions with the knee extensor muscles on an isokinetic device set at 4.36 rad/s. The knee extensions were preceded by isometric conditioning contractions of the antagonist knee flexor muscles. The conditioning contraction forces were 0, 25, 50, 75, and 100% of the maximum isometric force.
