NEW role of technology

• sports analytics is studying data from sports performances to try to improve performance
• quantitative.

  • formal, objective and systematic
  • takes into account factors that can be measured
• qualitative.

  • research focused on words which are descriptive
  • can be subject as they look at feelings, opinions and emotions
• objective data.

  • fact based information
  • measurable and usable
• subjective data.

  • data based on opinions, assumptions, interpretations, emotions and beliefs
  • less suitable for feeding back to performers
• validity.

  • degree to which data collected actually measures what they claim to measure
• reliability.

  • collected data is consistent and similar results are achieved when its repeated
  • reliability affected if equipment not used correctly or its poorly maintained
• data needs to be reliable and valid for it to be useful
• video and analysis programs help with understanding biomechanical aspects of performance and can help with rehabilitation from injury
• video motion analysis

  • uses high speed camera and computer software to allow for frame-by-frame playback of footage
  • notational match analysis - records aspects of individual and team performance. studying movement patterns, strategy and tactics
  • biomechanics - analysis sporting impacts of bodily movements, quantitative study (kinematics)
• performance analysis helps performers ensure they have a positive change in performance and can be gained through a variety of

  indicators such as passes made, distance ran in km and shots attempted
• testing and recording equipment - metabolic cart

  • measures bodys metabolism through amount of heat produced when body is at rest
  • can tell doctors about overall health
  • indirect calorimetry is the measurement of amount of heat and energy generated in an oxidation reaction. headgear placed on patient and measures inspired/expired gas flows, concentrations and volumes of oxygen and carbon dioxide. these measurements then translated into heat equivalent
  • figure of oxygen and carbon dioxide provide result for metabolic cart and is measured in resting energy expenditure
