Footnotes from the Field

Here’s what the sports science team at IMeasureU is reading this week:

  1. How Much? How Fast? How Soon? Three Simple Concepts for Progressing Training Loads to Minimize Injury Risk and Enhance Performance

It is well established that a balance exists between providing an adequate training stimulus to elicit performance benefits while also minimizing the risk of injury. How can practitioners determine how much training is too much? Following injury, how soon can training loads be progressed? How quickly can athletes return to competition? This editorial in the Journal of Orthopedic Sports Physical Therapy from Tim Gabbett explains three key concepts, ‘floor’, ‘ceiling’ and time which are all crucial to developing performance and rehabilitation programmes.

  1. Reliability and magnitude of loaded countermovement jump performance variables: a technical examination of the jump threshold initiation

The second article in this weeks list comes from Alejandro Pérez-Castilla in Sports Biomechanics. This study examined the influence of the jump starting threshold on the reliability and magnitude of loaded countermovement jump (CMJ) performance variables. Although maybe not the most exciting of subjects, these details are crucial if you are collecting jump data.

  1. “How Am I Going, Coach?”-The Effect of Augmented Feedback During Small-Sided Games on Locomotor, Physiological, and Perceptual Responses.

The final article comes from Jonathon Weakley and the team at Leeds Beckett University. This paper is published in the International Journal of Sports Physiology and Performance and investigates whether providing global positioning system feedback to players between bouts of small-sided games (SSGs) can alter locomotor, physiological, and perceptual responses. They concluded that verbal feedback did not alter locomotor, physiological, or perceptual responses in rugby players during SSGs. This may be due to contextual factors (eg, opposition) or the type (ie, distance) or low frequency of feedback provided.
