TLDR
It was concluded that the squat jump provides a standardised and reproducible reference EMG value for the triceps surae for use as a normalisation method.
Influence of dynamic versus static core exercises on performance in field based fitness tests.

TLDR
Comparing a 6 week unstable static versus unstable dynamic core training program on field based fitness tests indicates that both types of training improved specific measures of core stability but did not transfer into any sport-related skill.
Mental fatigue does not affect maximal anaerobic exercise performance
TLDR
Near identical responses in performance and physiological parameters between mental fatigue and control conditions suggest that peripheral mechanisms primarily regulate maximal anaerobic exercise.
A review of models of vertical, leg, and knee stiffness in adults for running, jumping or hopping tasks
TLDR
To review literature which describes how vertical, leg and knee stiffness has been measured in adult populations while running, jumping or hopping, and sample size issues and measurement techniques were identified as limitations to current research.
Athletic ability assessment: a movement assessment protocol for athletes.
TLDR
Results of the reliability analysis suggest high levels of agreement between scorers for total scores and provide reference values for minimal detectable changes using the Athletic Ability Assessment.
Electromyography normalization methods for high-velocity muscle actions: review and recommendations.

  • Engineering, Medicine
    Journal of applied biomechanics
  • 1 October 2013
TLDR
It is posits that, to date, methodological approaches to normalization have been ineffective and have limited the application of electromyography (EMG) and should be corrected to improve EMG application in sports.
Muscle pre-activation strategies play a role in modulating Kvert for change of direction manoeuvres: an observational study.
TLDR
Results suggest that muscle pre-activation strategies play a role in modulating Kvert for change of direction manoeuvre and moderate to strong positive relationships were typically seen for Kvert.
Bilateral Neuromuscular and Force Differences During a Plyometric Task
  • N. Ball, J. Scurr
  • Medicine
    Journal of strength and conditioning research
  • 1 August 2009
TLDR
This study showed differences between left and right triceps surae in neuromuscular strategies engaged in the early stages of a drop jump task and found weak relationships between normalized electromyographic activity and nonsimultaneous foot contact.
The effect of limb dominance on lower limb functional performance – a systematic review
TLDR
There was no statistical effect of limb dominance for any of the functional tests: isokinetic quadriceps and hamstring tests, hamstring:quadriceps ratios, single-leg hop for distance,single-leg vertical jump and vertical ground reaction force following a single- leg vertical jump.
Mechanisms and Risk Factors for Noncontact ACL Injury in Age Mature Athletes Who Engage in Field Or Court Sports: A Summary of the Literature Since 1980
TLDR
It is concluded that there are still a number of risk factors and mechanisms for noncontact ACL injury that are not well understood and it is suggested that novel methods for preventing ACL injury be investigated and developed.
