5 Effects Of Low-intensity Concentric Combined With Blood Flow Restriction On Achilles Tendon
2014
Introduction Weight training is a useful tool in order to achieve muscular hypertrophy. However, the American College of Sports Medicine (ACSM) recommends intensities of 70% of one repetition maximum (1-RM). Those intensities may not be suitable for everyone because of the high mechanical stresses placed upon the joints [Loenneke, 2012]. Nowadays, it is common to combine low-intensity exercise (20–30% 1-RM) with blood flow restriction (BFR) because of the beneficial effects in increased muscular strength, hypertrophy, localised endurance and cardiorespiratory endurance [Pope, 2013]. Despite there is not many papers about the beneficial of this training, it is know that the tendon suffers so…
Análisis de la distancia recorrida en pádel en función del nivel de juego y el número de puntos por partido (Analysis of distance covered in padel ba…
2020
La distancia que recorren los jugadores por partido supone una forma de cuantificar el volumen de carga externa del juego, y su estudio tiene una gran aplicación en la planificación del entrenamiento deportivo. El objetivo de este estudio fue analizar la distancia recorrida en diferentes fases del partido (activa y pasiva) y su relación con el número de puntos disputados y nivel de juego de los deportistas. La muestra estuvo compuesta por 108 jugadores federados de pádel (edad media = 33.81 ± 6.72 años). Se analizaron, a través de observación sistemática con el sistema SAGIT, un total 4406 puntos correspondientes a 27 partidos de pádel. Los partidos fueron divididos en tres niveles de compe…

Neuromuscular and mobility responses to a vibration session in hypoxia in multiple sclerosis
2020
AbstractThe aim of this study was to investigate the acute effects of vibration training (WBVT) under hypoxic and normoxic conditions on the voluntary rate of force development (RFD), balance and muscle oxygen saturation (SMO2) in persons with Multiple Sclerosis (MS). 10 participants completed the study (30% males, 44.4±7.7 years, 164.3±8.9 cm, 65.2±11.1 kg, 2.5±1.3 Expanded Disability Status Scale, 24.1±4.0 kg.m−2 BMI). Maximal force, RFD during isometric knee extension, static balance with eyes open and closed and sit-to-stand test were evaluated before and immediately after one session of WBVT (12 60-s bout of vibration; frequency 35 Hz; amplitude 4 mm; 1-min rest intervals) under both n…
Acute effects of cold pack on mechanical properties of the quadriceps muscle in healthy subjects.
2012
Purpose: To examine the effects of local cooling on mechanical properties of the quadriceps muscle in healthy subjects. Subjects: Thirty-nine healthy subjects (27 women, 12 men, mean age 39, range 20e62) volunteered. Methods: A cold gel pack was applied to the quadriceps muscle for 20 min. Properties were quantified by analyzing the frequency (tension), decrement (elasticity) and stiffness of damped oscillations and the compliance of the muscle before, immediately after and after 15-min after cooling. Results: The largest responses immediately after cooling were seen in the oscillation decrement parameter, 7.9 (3.7e12.1) %, and in the compliance parameter, � 7.5 (� 9.8 to � 5.3) %. Response…
Want to Impact Physical, Technical, and Tactical Performance during Basketball Small-Sided Games in Youth Athletes? Try Differential Learning Beforeh…
2020
This study aimed to analyze the acute effect of small-sided games, based on differential learning, on the physical, technical, and positioning performance of young basketball players. Eight basketball players under 13 (U13) participated in this study. A total of eight sessions involving half-court small-sided games (4 sets ×
Kinematic characteristics of barefoot sprinting in habitually shod children
2018
Background Anecdotally, a wide variety of benefits of barefoot running have been advocated by numerous individuals. The influence of the alterations in the properties of the shoe on the running movement has been demonstrated in adults at submaximal jogging speeds. However, the biomechanical differences between shod and barefoot running in children at sprinting speeds and the potential developmental implications of these differences are still less examined. The purpose was to determine the potential differences in habitually shod children’s sprint kinematics between shod and barefoot conditions. Methods Ninety-four children (51 boys and 43 girls; 6–12 years-old; height, 135.0 ± 0.12 m; body…
Resistance Training Acutely Impairs Agility and Spike-Specific Performance Measures in Collegiate Female Volleyball Players Returning from the Off-Se…
2020
This study examined the acute effects of resistance training (RT) on volleyball-specific performance. Sixteen female volleyball players undertook their initial, pre-season RT bout. Countermovement jump (CMJ), delayed onset of muscle soreness (DOMS), and sport-specific performances (i.e., run-up jump, agility, and spiking speed and accuracy) were measured before, 24 (T24), and 48 (T48) hours after RT. A significant increase in DOMS was observed at T24 and T48 (~207.6% ±
