Q

GPS definition:

A
  • a space based navigation system that provides location and time information.
22
Q

Why are GPS and motion tracking software and hardware used?

A
  • these systems give coaches a vast amount of information immediately at the touch if a button on a computer. They track the speed, distance and direction of individuals being monitored. They can also measure a player’s HR, pace , recovery time and the amount of dynamic acceleration.
  • in high contact sports (e.g. rugby) it can measure the amount of ‘G’ forces.
  • it can help coaches to make objective decisions about possible replacements and substitutes and can help to decrease injury as they can help gauge a performer’s fatigue level.
23
Q

Why do clubs use GPS technology?

A
  • makes better use of training time /ensures training meets game demands
  • improves the tactical analysis undertaken by club.
  • helps a coach to compare player performance and potentially ‘pick up the best player’ for the team based on GPS data.
  • helps to get injured players successfully through rehab at a faster rate.
  • non-elites: strata, map my run.
24
Q

A
  • maintaining and ensuring the accuracy and consistency of stored data over its entire lifetime.
25
Q

Data integrity using sports analytics definition:

A
  • refers to the validity of data (i.e. its relevance/meaningfulness
26
Q

How can data integrity be compromised?

A
  • human error when data is entered
  • errors occur when data is transmitted from one computer to another
  • software bugs or viruses
  • hardware malfunction such as disk crashes.
27
Q

What are ways to minimise threats to data integrity?

A
  • regularly backing up data
  • controlling access to data and protecting against malicious intent via security mechanisms.
  • designing interfaces which prevent the input of invalid data, taking care when entering data.
  • using error detection and correction software when transmitting data.
  • not leaving a composter unattended for anyone to access.
28
Q

29
Q

Use of analytics in injury prevention

A
  • vibration training and electrostimulation
30
Q

What is vibration training?

A
  • vibration training therapy is also known as whole body vibration (WBV) and an example of its usage involves the use of vibration plates to induce exercise effects in the body.
  • it can be used for recovery, injury prevention and rehabilitation.
31
Q

What are the benefits of vibration training?

A
  • improving bone density
  • increasing muscle mass/muscle power
  • improved circulation
  • reducing joint pain
  • reducing back pain
  • alleviating stress
  • boosting metabolism
  • an overall reduction in pain/DOMS
  • maintenance of cartilage integrity where weight bearing activities are difficult to undertake.
32
Q

What is electrostimulation?

A
  • the production of muscle contraction using electrical impulses
33
Q

How does electrostimulation work?

A
  • it works by providing a gentle electrocution of muscles to stimulate them.
  • Reproduces what an individual’s brain does to the nerves and muscles when they are voluntarily contracted. The only difference is the electrodes which are attached to a persons skin, send small shocks or impulses to the muscles without affecting the CNS or the brain.
34
Q

What are the benefits of electrostimulation?

A
  • an increase in strength and power
  • increased recovery time from training by expelling the lactic acid after a workout is over
  • it can also stimulate the muscles
  • promoting blood flow during a warm up
35
Q

Why is electrostimulation used in physical therapy (rehabilitation)?

A
  • helping to prevent muscle atrophy which can occur from disuse, e.g. after musculoskeletal injuries where damage to Jews, muscles, joints, ligaments and tendons occur.
  • helps prepare for competitions an aid to develop strength through the ability to train harder.
  • like any other electrical device, it is important not to overuse E/S as long term exposure is views as highly ineffective.
  • saturation is indeed possible and if an individual’s muscles gets stimulated for too long, they can get exhausted and stop contracting.
  • therefore, the use of E/S needs to be carefully planned and integrated into a training programme in order for it to be an important training aid.
36
Q

How does electrostimulation aid in the prevention of injuries?

A
  • by strengthening and toning the muscles to help prevent injury (e.g. it can strengthen the muscle groups of the legs to give stability and help prevent injury or recurring injuries to the knees and ankle)
  • by helping to prevent losses in fitness levels via application to specific muscle groups which maintains muscles tone during periods of inactivity.
  • by assisting un rehabilitation through the gradual strengthening of injured or weakened muscles via small incremental increases in workload on the muscles (e.g. including stronger muscular contractions) as part of rehab.
  • by helping to get rid of lactic acid after a training session or competition, as well as decreasing muscle tension and potential injury by providing a relaxing effect to muscles.
