Rob Grey did a podcast episode during which he talked a couple of paper titled Making use of the constraints-led method to facilitate exploratory studying of the volleyball serve. The main focus of the analysis achieved for the paper is the Tennis Serve idea I’ve written about earlier than. That’s the place you enable a re-serve if a gamers misses their try.
This analysis is introduced throughout the Constraints Led Strategy (CLA) framework (give Rob’s first e book a learn to study extra on the topic). That may sound a bit incongruous. In spite of everything, permitting a second serve doesn’t sound constraining.
On this occasion, nonetheless, it’s about eradicating a constraint. The truth that lacking a serve means you don’t get one other alternative is described as a “charge limiter”. Permitting the second serve lifts that limiter – not less than till it’s time to make a second serve.
The authors’ expressed intention for this analysis was “…to look at whether or not the addition of the duty constraint of a second serve would encourage volleyball gamers to make use of their first serve to discover their motion capabilities.” In different phrases, they needed to see if gamers took extra possibilities in the event that they knew they’d get a second serve on a miss.
Their findings point out – each empirically and from participant feedback – that’s precisely what occurs. No shock there for me. I’ve used second serves for fairly some time now for precisely this cause.
Rob fairly appropriately notes some limitations of the analysis. Lengthy-term outcomes, specifically, are a query. I feel, although, that this opens the door to wanting past serving. There are, in any case, the speed limiters at each level of contact. What if, for instance, we utilized the identical method to hitting? Would we see attackers attempting extra issues? I believe we’d (see Second Likelihood).
And flipping that round, the place might we add charge limiters to encourage or discourage sure issues?
Importantly…
Rob additionally makes a vital level towards the top of the episode. He notes that CLA isn’t nearly letting athletes do no matter till they in the end determine it out. “Coaches know what a very good serve seems to be like,” is his remark. Teaching beneath CLA is about guiding the athlete towards that via suggestions and/or using different constraints. It’s simply not about giving them the precise resolution.
