Journal ArticleDOI
Velocity loss as an indicator of neuromuscular fatigue during resistance training.
TL;DR: The high correlations found between mechanical (velocity and countermovement jump height losses) and metabolic (lactate, ammonia) measures of fatigue support the validity of using velocity loss to objectively quantify neuromuscular fatigue during resistance training.
Journal ArticleDOI
Movement velocity as a measure of loading intensity in resistance training.
TL;DR: An inextricable relationship between relative load and MPV in the BP that makes it possible to evaluate maximal strength without the need to perform a 1RM test, or test of maximum number of repetitions to failure (XRM); determine the %1RM that is being used as soon as the first repetition with any given load is performed.
Journal ArticleDOI
Importance of the propulsive phase in strength assessment.
TL;DR: This study analyzed the contribution of the propulsive and braking phases among different percentages of the one-repetition maximum (1RM) in the concentric bench press exercise and determined the relative load that maximized the mechanical power output (P(max).
Journal ArticleDOI
Differential effects of strength training leading to failure versus not to failure on hormonal responses, strength, and muscle power gains

TL;DR: This investigation demonstrated a potential beneficial stimulus of NRF for improving strength and power, especially during the subsequent peaking training period, whereas performing sets to failure resulted in greater gains in local muscular endurance.
Journal ArticleDOI
Effects of long-term training specificity on maximal strength and power of the upper and lower extremities in athletes from different sports.
Mikel Izquierdo,Keijo Häkkinen,Juan José González-Badillo,Javier Ibañez,Esteban M. Gorostiaga +4 more
TL;DR: The data suggest that the magnitude of the sport-related differences in strength and/or muscle power output may be explained in part by differences in muscle cross-sectional area, fibre type distribution and in the muscle mechanics of the upper and lower limbs as well as by training background.
