Accelerometry This section provides an overview into the use of accelerometry in sports and exercise. Steve Barrett very kindly agreed to give us his insights. He has worked with this system for longer than anyone I know and therefore I feel best placed to share his thoughts on accelerometry. Accelerometers have recently been introduced within the elite sport domain to quantify and monitor the external training loads within different sports as a measure of mechanical load.
As with all methods used currently it is important to understand the origin and the evolution of these currently used techniques to establish how they can be effectively applied in monitoring athletes.
Accelerometers within pedometers measure the number of steps taken by an individual which are identified by the spikes in the uni-lateral accelerometer working in the vertical plane. This led accelerometers to be incorporated into new technology, where the data was originally assessed as accelerometer counts per minute. However, accelerometers were mainly applied within short and low level physical activity tasks or treadmill running Halsey et al.
Now we have transferred the application of this data into intermittent, multi-directional, high intensity exercises such as soccer match-play. Have we potentially skipped steps within the research in order to understand the true meaning of this data we are receiving?
Through the introduction of MEMS devices microelectircal mechanicalsystems; such as GPS devices containing other inertial sensors such as accelerometers it has become obvious that using accelerometer counts per minute within high intensity activities such as soccer match play are not easy to manage as a result of large unmanageable numbers. Manufacturers in conjunction with research partners introduced algorithms into their software to make this accelerometry data easier to manage accumulating the accelerations in three planes of movement.
Interestingly, the use of accelerometry within the team sports research is still relatively new and with few research articles published on them pubmed search for tri-axialaccelerometers in sport results in 14 findings, with player load in sport producing 55 research papers, 6 specifically investigating the accelerometry derived player load. The research articles out there are descriptive in nature and very similar to the initial papers on motion analysis within the team sport domain, where basic variables, are being reported.
One way that we have to view all our data is to analyse it for what it is and not become over concerned with knowing which is better. If we take heart rate, accelerometers and RPE, we are using 3 variables that are measuring three different strands to our overall loading model.
Internal heart rate is a tool to assess how our cardiovascular system copes with the external and sometimes psychological loads placed upon the body.
With RPE we are asking players how hard they found the session, which is why we see such strong correlations with heart rate and accelerometer data in certain scenarios and environments. Accelerometers tri-axial assess the accelerations our body go through in the different planes of movement.
