Aging brings multiple physiological changes: loss of muscle mass (sarcopenia), declines in strength (dynapenia), neuromuscular alterations, reduced functional capacity, and increased risk of falls, frailty, dependence, hospitalizations, and premature mortality. These losses are not wholly inevitable — strength (resistance) training has emerged as an effective intervention to slow, attenuate, and sometimes partially reverse these adverse […]
Abstract Vertical jump ability is one of the most important indicators of explosive power in sports such as basketball, volleyball, and soccer. Its improvement depends not only on muscular strength but also on the efficiency of the stretch-shortening cycle (SSC). In recent years, eccentric overload training with flywheel devices such as the YoYo system has […]
Abstract The Achilles tendon is the strongest and thickest tendon in the human body, playing a decisive role in running, sprinting, and jumping. Its elastic properties enable efficient storage and release of energy, directly influencing speed and performance. Optimal stiffness and remodeling of this tendon are key factors for sprint ability and injury prevention. […]
Abstract Knee tendinopathies, particularly patellar tendinopathy, represent one of the most common causes of chronic anterior knee pain in athletes engaged in sports involving repetitive jumping, acceleration, and changes of direction, such as soccer and basketball. Traditional treatment approaches have relied heavily on linear eccentric training, especially decline squats. However, the use of flywheel […]
Abstract Hamstring muscle injuries represent one of the most prevalent problems in professional soccer and other high-demand sports. Recurrence rates are high, and return-to-play times are often prolonged, which highlights the need to optimize rehabilitation protocols. Eccentric training with flywheel devices has emerged as a promising tool to enhance muscle healing, support tissue […]
In the ongoing pursuit of optimizing health and physical performance, understanding fascia and biotensegrity has emerged as a crucial area of study. These two concepts, though relatively new in the fields of training and rehabilitation, offer a revolutionary perspective on how to maintain the body’s balance and optimal function. What is Fascia? Fascia is a […]
In the world of physical training and rehabilitation, understanding how to maintain joint stability during high-intensity movements is essential for preventing injuries and maximizing performance. A fundamental aspect of this stability is the phenomenon known as co-contraction, which plays a crucial role in joint protection and the effectiveness of intense exercises. What is Co-Contraction? Co-contraction […]
Muscle co-contraction is a key phenomenon in the biomechanics of movement, especially in high-intensity activities. For physical trainers and physiotherapists, understanding how and when co-contraction occurs can be crucial for optimizing athletic performance and preventing injuries. Definition and Mechanism of Co-Contraction Co-contraction refers to the simultaneous activation of antagonist muscles, meaning muscles that have opposite […]
Sprinting is one of the most intense forms of exercise in athletics, where maximum speed generation and movement efficiency are crucial. One fundamental aspect that influences performance during sprinting is muscular stiffness, or “stiffness.” This article explores how muscular stiffness affects ground reaction forces (GRF) during sprinting and why this is relevant for physical trainers […]
Sprinting is a fundamental discipline in athletics, characterized by high-speed, precise technical execution. In the biomechanical study of this technique, biomechanical attractors play a crucial role in describing how movement patterns stabilize for optimal performance. These attractors represent stable movement patterns that emerge from the interaction between biomechanical forces and the individual characteristics of the […]
