Sprinting involves a quick acceleration phase followed by a velocity maintenance phase. During the initial stage of sprinting, the runners have their upper body tilted forward in order to direct ground reaction forces more horizontally. As they reach their maximum velocity, the torso straightens out into an upright position. The goal of ...
The LESS is a valid and reliable tool for the biomechanical assessment of the jump landing technique. [1] [2] The LESS involves the scoring of 22 biomechanical criteria of the lower extremity and trunk, with the outcomes being associated with the risk of anterior cruciate ligament (ACL) and patellofemoral injury.
Gluteus maximus activity was substantially higher in maximal effort jumping and punching than sprinting, and substantially higher in sprinting than in running at speeds that can be sustained. The activity levels are not consistent with the suggestion that the muscle size is a result of selection for sustained endurance running. [ 22 ]
Sports biomechanics is the quantitative based study and analysis of athletes and sports activities in general. It can simply be described as the physics of sports. Within this specialized field of biomechanics, the laws of mechanics are applied in order to gain a greater understanding of athletic performance through mathematical modeling, computer simulation and measurement.
Running economy (RE) a complex, multifactorial concept that represents the sum of metabolic, cardiorespiratory, biomechanical and neuromuscular efficiency during running. [1]: 33 [2] [3] Oxygen consumption (VO 2) is the most commonly used method for measuring running economy, as the exchange of gases in the body, specifically oxygen and carbon dioxide, closely reflects energy metabolism.
Mechanography (also referred to as jumping mechanography or Muscle Mechanography [1]) is a medical diagnostic measurement method for motion analysis and assessment of muscle function and muscle power by means of physical parameters. The method is based on measuring the variation of the ground reaction forces over the time for motion patterns ...
The results of these often contradictory studies have been associated with improved efficiencies for human or animal movements such as counter-movement jumps and running.
Biomechanical factors associated with elite runners include increased hip function, use, and stride length over recreational runners. [ 36 ] [ 42 ] An increase in running speeds causes increased ground reaction forces, and elite distance runners must compensate for this to maintain their pace over long distances. [ 43 ]
