We’ve all seen the memes of riders who spend their complete saddle time staring down at their laptop models reasonably than the world round them. However is data energy because the saying goes, or can an excessive amount of knowledge or suggestions be adverse to efficiency?

Probably the most well-known stem starer

Stem Staring

Rightly or wrongly, Chris Froome was the poster boy for memes about riders observing their stems or bike computer systems, resulting in all types of debate about robotic racing and concepts about banning energy meters. Froome truly claims it’s his pure physique alignment and posture on the bike reasonably than an obsession with knowledge.

In lab experiments, we typically have contributors carry out time trials with none suggestions (energy, distance, HR, cadence, and so on.), as we wish to see their pure pacing technique. In monitor racing, you’re allowed to report knowledge, however the laptop must be hidden out of view. Off the boards, we are going to nearly at all times know the gap of the race, and our computer systems give us entry to a virtually infinite array of potential knowledge.

So what is perfect? If we wish to nail our membership time trial, ought to we go the monitor or the street route? If the latter, how a lot information is an excessive amount of information?

I beforehand wrote a couple of 2017 examine about simply what knowledge factors skilled and non-experienced cyclists deal with.

Bayne et al. 2020

Having a single versus a number of knowledge suggestions out there throughout time trials was the main focus of a UK/Qatari examine (Bayne et al. 2020). Additionally they examined the results of suggestions on skilled versus inexperienced cyclists. Right here the principle experimental particulars.

• 10 skilled cyclists (> 2 years of biking or triathlon competitors) and 10 match (> 5 h of exercise per week) non-cyclists.
• A 30 min lab time trial was the check, with the purpose of highest common energy or work performed throughout this time. Take a look at was performed in 18°C with a slight wind.
• The only suggestions situation was elapsed time.
• The a number of suggestions consisted of time, distance, pace, cadence, watts, and coronary heart fee.
• Eye monitoring software program was used to see how lengthy contributors checked out completely different knowledge factors.

The Eyes Have It

An attention-grabbing query executed with an applicable and simple analysis design.

As seen within the backside graph of this determine, all teams (CTMF = Cyclists, a number of suggestions; CTSF = Single suggestions; NCMF = Non-cyclists), had comparable pacing methods no matter expertise or suggestions amount. For the non-cyclists, single or a number of suggestions had no impact on efficiency, with common wattage 131 and 137 W with single and a number of suggestions, respectively. This might counsel that knowledge availability was secondary to pure health and expertise.

The skilled cyclists offered fairly a distinct response to suggestions, nevertheless. With single suggestions, their common energy was 288 W. Nonetheless, with a number of suggestions, there was an enormous drop right down to 228 W, regardless of comparable scores of perceived exertion. This might counsel that the presence of a lot suggestions led to data overload and distraction from the duty at hand.

Diving deeper into the attention monitoring knowledge, it’s not shocking that the cyclists glanced most frequently and in addition spent essentially the most time glancing at energy, though their notion was that they glanced most at pace. One different attention-grabbing remark was that the full period of time glancing at knowledge decreased over the 30 min time trial. This might counsel a shift to specializing in inside cues over time, or doubtlessly cognitive fatigue from data overload.

Watch the place you’re going

Eyes on the Highway!

Primarily based on this examine, the recommendation for time trials and perhaps even climbing or KOM-hunting could also be to simplify your laptop display screen. Stick to one (e.g., energy, common energy, cadence) or at most two metrics (e.g., add in time, distance or distance-to-go).

I can’t conclude this examine with no warning. This was performed within the lab on a stationary bike. Out on the street, preserve your eyes up and alert!

Simplify your life. Go minimalist and go quick!
