After working in all levels of collegiate basketball, I’m comfortable to say I know how to ball on a budget.
In the last decade, with the emergence of wearable technology and training specific software, the field of high performance has expanded exponentially into the field of sport science.
Today, coaching - both sport and performance, has evolved to be somewhat synonymous with sport science.
In fact, ESPN even jumped on the bandwagon and developed its own show ‘Sport Science’ to breakdown the physics of sport.
But what happens when you don’t have 3D biomechanical markers, force plates or wearable player-load-tracking technology?
For one, you can feel left behind.
But even that doesn’t stop sport coaches and administrators piling pressure on performance personnel to incorporate sport science in their program.
So, if resources don’t allow, how can one achieve this?
Here are two ways to leverage sports science on a budget.
Internal Player Load via RPE (Rate of Perceived Exertion)
Player load is one of the most significant and tracked performance metrics.
In the basketball world, the San Antonio Spurs infamously brought it to the public’s attention by resting their all-stars in the middle of a season.
There are two main aspects of player load: external and internal.
To put it simply, external player load is what is demanded of players: practice duration, number of repetitions and distance covered. In response, the body’s internal load is the physiological reaction to the imposed demand – for example the fluctuation of heart rate.
If you lack a wearable resource, you can still get a reliable internal load metric by using Rate of Perceived Exertion (RPE). This is a ‘perceived’ rating on how hard (or not) an athlete has worked.
In my experience, I have shifted from the traditional scale ranging from 1-10, and instead use an RPE scale of 6-20. This roughly correlates to average heart rates, with a score of 6 equating to an average heart rate of 60 beats per minutes, a 13 equating to 130 beats per minute, etc.
While you could stop there and get a subjective heart rate score for a session, I prefer to add a time component, such as practice duration, to paint a better picture. By doing so, you can generate a quasi Training Impulse, or TRIMP, score.
I use the following equation to generate an internal load:
Internal Load = RPE (6-20) x Practice Duration (minutes)
The other data I like to collect is purely subjective, in the form of a wellness questionnaire.
Questions I include are: sleep, fatigue, soreness, stress and mood related.
However, the number and nature of the questions can be adapted to whatever suits your situation the best. Questions are assigned values 1 to 5 and are totalled to formulate a score.
I prefer to look and track total scores over time, team averages, as well as total individual scores versus team averages. These seem to give great insight into how players adapt to demands, how the team is feeling, and how players are feeling about their current respective situations.
In my opinion, there is significant value in having athletes complete questionnaires multiple times a week, if not daily. Not only does it establish a better baseline, it also reduces the chances of outliers, such as an athlete being in an unusually bad mood or having a terrible night’s sleep.
Furthermore, I believe this gives the performance coach ample opportunity to assess, open conversations, and build relationships.
We live in an athletic culture that encourages a ‘Keeping Up With the Jones’ mentality and takes-up technology at a rapid pace.
The use of technology should enhance athletic performance, but data is only good if insights are learnt and behaviour is modified. I believe that coaches who don’t embrace modern sport science (even just the methods above) will not be as valued as those who do.
Technology can’t replace coaches, but they can certainly make them better. Both the wellness & RPE suggestions above can be achieved on a budget with a simple google forms questionnaire, or an inexpensive athlete management system that’s friendly on the wallet and improves athlete buy-in.
It can also be true that the playing field is uneven when it comes to adopting sport science technologies. So, by being creative, performance coaches can still manage and integrate sport science without the use of wearable technology.
As far as trying out an RPE and wellbeing tool that suits any budget, you can download a free 7-day Lumin Sports demo.
"As a professional cycling team we have athletes based all over the world, and at times we don’t see them in person for several weeks during the season or months during the off season, and even longer in the current climate. The Lumin Arc platform and Phila app allow us to simplify and centralise both qualitative and quantitative data on the athletes and is a valuable tool for us both for helping with team selection decisions, but also for general monitoring of the athletes health and well being."
"Lumin's Arc platform is a game changer in professional cycling. Arc has given our team real insights into the athlete’s performance and how they are feeling and training every day. This has and will continue to improve our decision making in a globally disparate team."
"We are a sport and a team with such a diverse work force which is geographically dispersed. Keeping in touch with each other is critical , every day that a rider is not able to train is a day lost to the team and to the rider. Technology and the partnership with Lumin has enabled us to be more connected than ever in a meaningful and relevant way, keeping us on the road."
"I can comfortably say that Lumin has saved us well over 40% in time spent collecting and preparing data, meaning we can spend more time putting the data to use."
“I am able to see all of my data in real time combined into the one system. Everything from my wellness to my performance data on one system is incredibly powerful. I’m able to connect all of my data to my coaches, performance staff and the people allowing me to be at my best. I’m able to integrate my 3rd party hardware and it will upload instantly to the Arc platform for instant analysis. As an athlete we often are asked to use a variety of different tools to monitor all of our performance metrics, With the Arc Mobile and Arc platforms this now consolidates this monitoring and data collection to very few seamless steps, allowing me to concentrate on racing and performing at my best."
"The Arc and Phila platforms have provided us with the ability to understand and monitor our group more in depth, while reducing our admin time with the data analysis perspective, giving us more time for what matters, developing our players on the field."
"The interactive, user-friendly nature of the platform helps to sort through large data sets to find the relevant information. With around 25-30% reduction in work-force across the league as a result of the COVID-19 pandemic, we have been able to maintain the same level of analysis across the 2021 season through the Arc platform."
"Since using Arc by Lumin Sports, we, as a high performance football team have been able to consolidate a-lot of our existing data storage and analysis platforms so that we can now use one central platform throughout the department. Seamless integrations with real time visuals has been at the forefront of my work and where I see the most benefit and potential from the Arc platform from my point of view."
