    Recognizing Sports Pseudoscience

    In a recent discussion with BJ Leroy of USA Volleyball, I encountered a paper by Bailey et al (2018) published in the open access journal Frontiers in Psychology, titled  “The Prevalence of Pseudoscientific Ideas and Neuromyths Among Sports Coaches“. Since the journal is open access, the paper is readily available to download and read. The paper is basically a study on the pervasiveness of pseudoscience among sports coaches, even with ideas that have been long established to be untrue. Dr. Ed Couglin wrote a layperson friendly (albeit Irish-centric) interpretation of the paper.

    Suffice it to say, pseudoscience is rampant in sports culture, and pervasive in beach volleyball. I’d say much of the sponsor economy is built around pseudoscientific beliefs, but I’ll address those specific examples in future articles. What I’d like to share here is an excerpt from the Bailey paper, that outlines some properties of pseudoscience which will help you identify it. Bear in mind, this also applies to how people may argue their points online.

    • Unfalsifiability
    • Absence of self-correction
    • Overuse of ad hoc immunizing tactics designed to protect theories from refutation
    • Absence of connectivity with other domains of knowledge
    • Use of unnecessarily unclear language
    • Over-reliance on anecdotes and testimonials at the expense of systematic evidence
    • Evasion of genuine peer review
    • Emphasis on confirmation rather than refutation.
  • Court behavior beyond the game

    Court behavior beyond the game

    When people picture beach volleyball culture, they usually just think about just the game. People don’t seem to have to think about how the ball, or the net, or the court itself got there. Like the illusion of cooking shows on TV, these things didn’t actually magically appear – specially in public parks and areas, someone had to lug all the equipment there. Someone had to lay down lines, set up the net, bring out the balls. And someone has to break it all down and clear it away at the end of the day.

    In many venues, that someone is one person, or a very small group of people. The same dedicated people who will usually come week after week, spend the money out of their pockets to sustain the active social gathering. Oddly, though, this labor quickly becomes invisible. Players come to a venue simply assuming that they are entitled to challenge onto the courts, and fight to hang on to the courts. The commonly used “challenge” system can mean that those who have worked hardest to maintain a venue can end up using it the least.

    The unspoken injustice shows up in the gambit where players try to find that optimal timing to arrive late enough to avoid helping with set up, and leave early enough to avoid breakdown, while conspiring to form stacked teams to play as much as possible. Or in some cases, openly await the availability of the court set up to “steal” it from the ones who have worked on it. Anecdotally, I’ve observed self-professed “advanced” players disdainful to assist in these matters, more concerned about spending time warming up or stretching out — with the unspoken implication that the this is the appropriate burden for novices.

    Many communities have these selfless organizers and abused leaders, who do this for the love of the game. Afford them a bit more respect, and help to sustain the community. Offer to play with them, specially if you are borrowing their equipment. And at the very least speak your gratitude. Curb the entitlement, for those who rise in recognition often do so on the shoulders of the dedicated silent lovers of the game.

  • Improving Quads 1: The net is not a player

    Improving Quads 1: The net is not a player

    Although a great deal of the instruction describes beach volleyball primarily as a doubles game, many, if not most, people are exposed to it in the 4v4 format. These articles focus on tips and discussions that improve the quads game.

    Conventionally, the quads game is treated as a novice version of the sport, with many players thinking that they can “graduate” to the doubles game. But the number of variables and potential plays are much greater with four players than two, and thus, it is a far more complex game to master. It combines many of the potential strategies from indoor volleyball, and couple it with the environmental challenges of beach volleyball, and while it can appear to be less daunting to a novice due to the greater number of people supporting any one player, communities of quads teams fall into limited set strategies and seldom progress to more sophisticated plays.

    Given the opportunity to teach quads players, I ask teams to let go of their ball control orientation with the net, a system that I also apply to beginning doubles players. Many quads teams fall into this idea of the diamond formation, where a setter is situated at near the middle of the net, and the other three players attempt to pass the ball to that spot near the net. This is derived from the indoor volleyball 4-2 passing formation, and thus appears to be relatively easy to communicate specially among players who have had exposure to indoor volleyball culture.

    But this approach demands precision passing to a set location on the court. This effectively creates a very high bar of body control, and is also poorly adaptable. By pegging the plays to specific coordinates on the court, the players are often taken off balance by factors like the weather, or just a strong float situation.

    If the team moves their coordinate system from having one team mate pegged to the net, and instead shift their passing focus to the area bounded by the imaginary boundaries formed by the four players, less precise passing becomes acceptable. This also frees the entire team to move as a unit, gaining confidence in having assistance nearby as they track the ball, instead of trying to change the distance constantly as the action moves nearer or farther from the net. Moreover, setting is also simplified, since the ball is brought to the attacker, rather than trying to coordinate interception of a ball being forced to the net.

    Adopting a team oriented control strategy as opposed to a court oriented one is more easily implemented when the athletes aren’t coming from a conventional indoor volleyball cultural background, where this more malleable passing formation can appear confusing.

  • “Call me off”

    “Call me off”

    I hear a number of common phrases during volleyball play which I discourage athletes from using. This is why. 

    “Call me off”

    This phrase is most commonly uttered when a player realizes that she had gotten in the way of her teammate who was likely to be in a better position to play the ball. Anecdotally, I tend to observe older players use this phrase on younger players, both as a way of establishing authority, but also as an escape from social consequences of admitting to a mistake. It’s a reversal of blame – not only is the original player not responsible for being unaware of her partner, it’s also her partner’s responsibility to be aware of her.

    I consider using this phrase aloud as a way of escaping responsibility, rather than learning from the circumstance. These circumstances, however, are good teaching examples of body awareness, and acknowledging that every movement one makes on the court can inadvertently affect the partner.

  • “Was that going out?”

    I hear a number of common phrases during volleyball play which I discourage athletes from using. This is why. 

    “Was that going out?”

    This phrase is most commonly uttered right after a player contacts a ball during defense and shanks it out of team control. It’s a peculiar question to ask of a team mate, because the outcome is already done. One cannot rewind to that specific situation again. What it does represent is a deflection of perceived responsibility. If the ball was indeed perceived to be going out, then I’ve seen the shanker blame her teammate for not warning her sooner. If it wasn’t, then the shanker was making a good effort play to just touch the ball. Using the phrase is a means of externalizing the issue instead of actively learning from it.

    The key here is developing good judgement to decide to play the ball so that it is in system, regardless of whether it was going out or not. It works best when the digger chooses to embrace the responsibility of taking the ball, confident in the team’s ability to convert the play, or accepting the heat for gambling the outcome of the rally for a potential quick point. Either way, the lesson is to accept and learn, rather than deflect and deny.

  • The Math and Consequences of Rally Point Scoring

    The Math and Consequences of Rally Point Scoring

    The adoption of rally point scoring fundamentally changed the strategy in beach volleyball. The original mintonette borrowed scoring from baseball with nine innings — but few people even remember that. Some, though, can probably remember the sideout scoring system, where a team must have served the ball to earn a point. Rallies won by the receiving team didn’t change the score – resulting in unpredictably long games. In the two man version of beach volleyball, the game evolved into a marathon, where grinding down your opponents by sheer endurance is a viable strategy.

    The modern rally point scoring system awards a point for the team winning the rally, regardless of who serves the ball. This small change ensures that with each rally the game proceeds towards the end point, which results in a more stable prediction of match durations. But what has remained unchanged is the need to earn the two point advantage to end the set at 21.

    The team receiving the serve usually has the first chance to attack and terminate the rally, earning the first point (“siding out”). Players settle into practicing this scenario often: it’s fairly easy to reproduce in isolation, can be made predictable, and for the attacking player, a feeling of strength crushing the ball against an imagined defenseless opponent. The components can be simplified into modular training parts: passing the ball to a set location on the court, setting with recognizable biomechanics, and attention paid to the velocity of the attack. But assuming that a team is proficient at siding out, the next point, they would have gained the responsibility of serving the ball – and handed the advantage of first attack to the other team.

    The equalizing nature of this rule means that the way to win is to earn your points without needing that service receive advantage at least twice. Not counting unforced errors, the three primary ways to earning the point advantage are:

    1. A service ace

    2. A stuff block (and its variants)

    3. A defensive conversion

    Of these three, the last is most common, and requires effective transition setting and smarter attacking. In general, practice should be weighted to focus on these play scenarios, but these are greater challenges for both coach and athlete. These do not easily break down into reproducible modules, nor does effectiveness arise exclusively from homogenous biomechanics. But learning to adapt to more chaotic conditions makes for a more effective team.
