The aims of this repeated measures study were (I) to determine the reliability of single-leg squat 1RM and inter-limb asymmetries in pre-pubertal athletes, and (II) to assess associations between bilateral and/or unilateral squat 1RM performance, inter-limb asymmetries, and participants’ chronological and biological age. Thirty-one soccer players (...

Background: The use of elastomeric technology in sports garments is increasing in popularity; however, its specific impact on physiological and psychological variables is not fully understood. Thus, we aimed to analyze the physiological (muscle activation of the pectoralis major, triceps brachii, anterior deltoid, and rectus abdominis, capillary bl...

The bulk of research on microfiltered seawater (SW) is based on its short-term effects. However, the long-term physiological adaptations to combining SW and resistance training (RT) are unknown. This study aimed to analyse the impact of an RT program using elastic bands combined with SW intake on hepatic biomarkers, inflammation, oxidative stress,...

The aim was to explore the effects of a 32-week resistance training (RT) intervention with elastic bands with or without microfiltered seawater (SW) supplementation on isokinetic strength, bone mineral density (BMD), body composition, and subjective quality of life in postmenopausal women. Ninety-three untrained women (age: 70.00±6.26 years; body m...

To compare the effects of playing one or two games per week on subjective perceived exertion (RPE) and (RPE-based) training load, monotony index, sleep, stress, fatigue, and muscle soreness (Hooper index), total mood disturbance, and injury rate in elite soccer players. Fourteen males from a first-division soccer club (age: 24.42 ± 4.80 years) comp...

Objetivo: Recopilar información sobre la activación del pectoral mayor en ejercicios de fuerza de empuje horizontal en los que se emplea una carga externa. Método: Se realizó una revisión en tres bases de datos distintas (PubMed, Web of Science y SPORTDiscus) hasta el 4 de mayo de 2022 bajo los criterios PRISMA (2020) (1). Los criterios de inclusió...

Introducción: La ciencia ha generado un debate sobre las consecuencias del entrenamiento de la fuerza en la presión intraocular (PIO), con artículos asegurando aumentos y otros encontrando disminuciones. Sólo un estudio previo ha analizado el uso de bandas elásticas para cargar la barra en sentadillas y ha obtenido disminuciones de PIO similares a...

Introducción: El empleo de bandas elásticas (BE) para cargar la barra en sentadillas ha mostrado adaptaciones agudas similares de presión intraocular (PIO) y presión de perfusion ocular (PPO) en comparación con discos. Sin embargo, las BE permiten realizar más repeticiones, probablemente debido a movilizar menos kilogramos por debajo del sticking p...

The aim was assessing the short-term effects of multicomponent training including some elastic exercises on body composition and balance in healthy older women. In two sessions/week for 12 weeks, 24 women performed 4 blocks of exercise in 2 experimental conditions: a) Control Group; b) Multicomponent Training Group (EMC). The following variables we...

Purpose: To compare perceived enjoyment (PE), % of heart rate peak (%HRpeak), blood lactate (La), rating of perceived exertion (RPE), and technical-tactical performance of soccer players after four-a-side (4vs4) and three-a-side (3vs3) small-sided games (SSGs) with goalkeepers. Methods: Sixteen males (20.7 ± 0.7 years; experience: 6.9 ± 1.2 year...

The deadlift is one of the most widely used resistance exercises by different types of trainees and with different aims including aesthetics, performance and health. There are numerous variations of the deadlift exercise which have different effects on the exercise biomechanics and muscular activation. The main objective of this research was to sys...

Literature have shown the positive effects of participation in classical sports on children health. However, innovative ideas are necessary to increase their participation according to motivations and individual needs. The purpose of the present study was to know if a new racket sport of reduced play space provokes similar physiological and psychol...

Chronic low back pain is a musculoskeletal pathology with a considerably high prevalence in the elderly. This condition increases disability and negatively affects the quality of life. Muscular resistance training is being used as a cornerstone in interventions for elder people due to the numerous benefits associated with physical and functional he...

The squat is one of the most commonly used resistance exercises for performance and health due to its biomechanical and neuromuscular similarities to a wide range of athletic and everyday activities. There is a large number of squat variations (based on the descent depth, width of the stance, bar placement) with significant biomechanical and neurom...

The positive importance of physical activity properly prescribed in terms of intensity and volume on a variety of metabolic, musculoskeletal, cognitive and other disorders is widely known. The increasing epidemiology of infertility is due to the changes in lifestyle habits, such as inappropriate diets or the radiations from new-generation electrica...

Methods: This study was a randomized controlled trial with pre- and postintervention measures. Participants included OOW, aged 60-85 years, with no medical history of disease that would preclude them from engaging in physical exercise. Participants were randomly divided into the following groups: elastic tubes with handles group (ETG; n = 22), tra...

Methods: Participants were randomly assigned to the high-intensity group (HIGH; n = 39), moderate-intensity group (MOD; n = 31), or control group (CG; n = 23). The exercise groups performed an RTP twice a week with three to four sets of 6 (HIGH) or 15 (MOD) repetitions of six overall body exercises at a perceived exertion rate of 8-9 on the OMNI-R...

Purpose: To examine the concurrent validity of the OMNI-Resistance Exercise Scale of perceived exertion using elastic bands in elder population. Methods: Twenty-six participants performed three separate sets of 15 repetitions (low- medium- and high-intensity) for 4 different exercises (2 for the upper-limb and 2 for the lower limb), over two dif...

Background Exercises providing neuromuscular challenges of the spinal muscles are desired for core stability, which is important for workers with heavy manual labour as well as people recovering from back pain. Purpose This study evaluated whether using a suspended modality increases trunk muscle activity during unilateral or bilateral isometric s...
