In this article, we will address common misconceptions about the mechanical characteristics of sprint acceleration. We’ll analyze concrete data based on measurements with force platforms, which are the gold standard in biomechanics. By comparing three different types of exercises, we can better understand how ground reaction forces affect acceleration and sprint performance. Analysis of Force […]
1. Contact Distance, Contact Time, and Vertical Force To begin, we examine the relationship between contact distance, contact time, and vertical force requirements. During the ground contact phase, the contact excursion angle is the total angle traveled by the leg. For most runners, this angle varies between 50 and 60 degrees, or approximately one radian. […]
Biomechanics of Directional Changes in Sports In the sports realm, the ability to change direction swiftly is essential for athletes’ performance across various disciplines. Over the past 20 years, multiple researchers have explored and classified directional change types, contributing to a deeper understanding of the biomechanics involved. In this article, we will delve into the […]
Recently, I had the incredible opportunity to attend a workshop on rotational power led by David Otey at the NSCA conference. It was an enriching experience that left me with much to ponder and apply in my training and that of my clients. I want to share with you everything I learned about this crucial […]
En este artículo, me gustaría abordar algunos conceptos erróneos sobre las características mecánicas de la aceleración en el sprint. Vamos a analizar datos concretos, basados en mediciones con plataformas de fuerza, que son el estándar de oro en la biomecánica. Mediante la comparación de tres tipos de ejercicios distintos, podremos entender mejor cómo la fuerza […]
Today’s discussion will focus on the physiological aspects affecting strength and power, specifically in the development of Rate of Force Development (RFD). To grasp this concept, it’s essential to understand force transmission through tissues as it affects our ability to produce force and develop the rate of force. What is Rate of Force Development? Rate […]
At Wheeler Academy Sports Science, we are dedicated to optimizing sports performance through science-based training. Today, we will cover how to perform a warm-up tailored to strength training for braking actions with lateral directional changes. These exercises are crucial in many sports where speed and efficiency in lateral movements can mean the difference between success […]
1. Distancia de Contacto, Tiempo de Contacto y Fuerza Vertical Para empezar, examinamos la relación entre la distancia de contacto, el tiempo de contacto y los requisitos de fuerza vertical. Durante la fase de contacto con el suelo, el ángulo de excursión de contacto es el ángulo total recorrido por la pierna. Para la mayoría […]
In the realm of sports performance, acceleration is a crucial component that can make the difference between success and failure. The initial steps in acceleration training are fundamental for developing an athlete’s ability to reach maximum speed quickly. This approach not only enhances speed and efficiency in sports but also boosts neuromuscular performance, enabling a […]
In the realm of human performance, understanding how movements are constructed and executed is crucial for enhancing sports performance, rehabilitation, and daily activities. Among the various theories that delve into this fascinating field, Bernstein’s theory on the construction of movements stands out as a unique and revealing perspective. Introduction to Bernstein’s Theory of Movement Construction […]
