Prevalence of disordered eating and its relationship with rapid weight loss amongst male and female combat sport competitors: A prospective study

OBJECTIVES

To compare prevalence and change scores of disordered eating (DE) in combat sport athletes by sex and explore the potential relationship between rapid weight loss (RWL) and DE scores.

DESIGN

Prospective study based on 24 events (September 2022-2023).

METHODS

A body mass (BM) questionnaire was completed at ~1 day post-competition providing pre-competition BM data for -7 days, -24 h, and weigh-in. The Athletic Disordered Eating (ADE) online questionnaire was completed at ~7 and ~28 days post-competition, providing overall DE and four subscale scores (food and energy control, bingeing, body control, and body discontent).

RESULTS

There were 122, 132, and 89 respondents for the BM (77 % male), and ADE questionnaires at 7 (79 % male), and 28 days (74 % male). A large proportion of males' (83 %) and females' (89 %) DE scores were moderate to very high; minimal (17 % vs. 11 %), moderate (36 % vs. 32 %), high (37 % vs. 36 %), and very high (11 % vs. 21 %). Comparing DE change scores in males and females indicated deterioration (5 % vs. 0 %), improvement (3 % vs. 25 %, p = 0.013), and no difference (92 % vs. 75 %). Body discontent change score showed a significant sex difference (p = 0.014), with females improving (42 % vs. 17 %, p = 0.035) and males deteriorating (35 % vs. 4 %, p = 0.008). Correlation analyses were significant for RWL -7 days and males' food control score (R = 0.22, p = 0.031).

CONCLUSIONS

Moderate to very high DE indications were identified in 4 of every 5 combat sport competitors. A sex-specific change in body discontent is evident, and most competitors struggle with their food-body relationship post-competition, irrespective of RWL magnitude.

Integrating Rough-and-Tumble Play in Martial Arts: A Practitioner's Model

This paper introduces a model that explains psychosocial development by embedding the developmental concept of rough-and-tumble play (RTP) into the contextual settings of martial arts (MA). Current sport-for-change literature relies on theories that address contextual factors surrounding sport but agrees that sport in itself does not facilitate developmental outcomes. In contemporary times where western societies invest substantial resources in sport programs for their psychosocial contribution, this becomes problematic. If the contextual factors surrounding sport are exclusively what produce developmental outcomes, what is the rationale for investing resources in sport specifically? We challenge this idea and argue that although contextual factors are important to any social phenomena, the developmental outcomes from sport can also be traced to the corporeal domain in sport. To date, we have lacked the theoretical lenses to articulate this. The developmental concept of RTP emphasizes how “play fighting” between consenting parties stimulates psychosocial growth through its demand for self-regulation and control when “play fighting” with peers. In short, RTP demands that individuals maintain a self-regulated mode of fighting and is contingent on a give-and-take relationship to maintain enjoyment. RTP can thus foster empathy and prosocial behavior and has strong social bonding implications. However, such play can also escalate. A fitting setting to be considered as moderated RTP is MA because of its resemblance to RTP, and its inherent philosophical features, which emphasizes self-regulation, empathy, and prosocial behavior. This paper outlines what constitutes high-quality RTP in a MA context and how this relates to developmental outcomes. By doing so, we present a practitioner’s framework in which practitioners, social workers, and physical educators can explain how MA, and not merely contextual factors, contributes toward developmental outcomes. In a time where sport is becoming increasingly politicized and used as a social intervention, it too becomes imperative to account for why sport, and in this case, MA, is suitable to such ends.
