Didactic adaptation of basketball in physical education to reduce anxiety and emotional eating in adolescent girls with obesity: a randomized controlled trial

The pervasive issue of childhood and adolescent obesity, a growing global health concern, disproportionately affects adolescent girls, rendering them vulnerable to a spectrum of physical and psychological health risks. Beyond the immediate concerns of cardiovascular disorders, hypertension, and metabolic syndrome, these young individuals often grapple with significant psychological challenges, including elevated anxiety, diminished self-esteem, body dissatisfaction, and a pronounced tendency towards emotional eating. These intertwined issues can create a detrimental cycle, impacting their overall well-being and potentially persisting into adulthood, underscoring the urgent need for effective, targeted interventions. In response to this critical need, a recent randomized controlled trial has illuminated the significant benefits of a didactically adapted basketball program in addressing these multifaceted challenges among adolescent girls with moderate obesity.

Key Findings from the Randomized Controlled Trial

A comprehensive 7-week intervention, meticulously designed to adapt basketball sessions for adolescent girls aged 15-16 years with moderate obesity, has yielded remarkable results. The study, involving 64 participants, revealed statistically significant improvements across several key health indicators for the group engaged in the adapted program compared to a control group receiving standard physical education.

The experimental group demonstrated a significant reduction in Body Mass Index (BMI), with a notable decrease observed from pre-intervention to post-intervention. This positive shift in body composition suggests that the adapted physical activity was effective in promoting healthier weight management. Crucially, the control group did not exhibit similar changes, highlighting the specific impact of the adapted intervention.

Beyond physical metrics, the psychological benefits were equally profound. Participants in the adapted basketball program reported a significant decrease in emotional eating behaviors, as measured by the Dutch Eating Behavior Questionnaire (DEBQ). This suggests that the program provided effective strategies for managing stress and negative emotions, thereby reducing the reliance on food as a coping mechanism. Concurrently, levels of sport-related anxiety, assessed using the Sport Anxiety Scale-2 (SAS-2), saw a substantial decline in the experimental group. This indicates that the adapted approach successfully mitigated apprehension and stress associated with physical activity and sports participation.

Furthermore, the intervention positively impacted technical performance in basketball. Participants in the adapted program showed enhanced accuracy in both passing and shooting drills. This improvement in motor skills suggests that the pedagogical adaptations not only addressed psychological barriers but also fostered a more conducive environment for skill acquisition and development.

A compelling correlation analysis revealed that reductions in sport anxiety and emotional eating were significantly associated with improvements in technical basketball performance. This finding underscores the interconnectedness of psychological well-being and physical skill development, suggesting that by addressing emotional and psychological hurdles, the program indirectly facilitated enhanced motor learning and execution.

Background: The Dual Burden of Obesity and Psychological Distress in Adolescence

Childhood and adolescent obesity has reached epidemic proportions globally, with a particularly high prevalence among girls. This demographic faces a unique set of challenges, where excess weight is often compounded by social stigma, reduced self-confidence, and a higher susceptibility to mental health issues. Emotional eating, a behavior characterized by consuming food in response to emotions rather than hunger, is a significant contributor to weight gain and maintenance in this population. It is often intertwined with anxiety, creating a vicious cycle where negative emotions trigger overeating, which in turn can exacerbate feelings of guilt, shame, and anxiety.

Traditional physical education (PE) settings can inadvertently heighten these issues. For adolescent girls with obesity, the demands of team sports like basketball, which require agility, coordination, and endurance, can be intimidating. A lack of tailored instruction or an overly competitive environment can lead to feelings of inadequacy, social exclusion, and a further disengagement from physical activity. This study sought to address this gap by implementing a basketball program with specific pedagogical adaptations designed to be inclusive, supportive, and skill-building, rather than solely performance-oriented.

Methodology: A Rigorous Randomized Controlled Trial

The study employed a robust two-arm, parallel-group randomized controlled trial design. Sixty-four adolescent girls, aged 15-16 years, who met the criteria for moderate obesity, were recruited from secondary schools in Sidi Bouzid, Tunisia. Participants were systematically selected based on age- and sex-specific BMI percentiles, adhering to World Health Organization (WHO) guidelines. Exclusion criteria were carefully managed to ensure participant safety and the integrity of the study, including the absence of significant health disorders and the requirement for parental consent.

Participants were randomly assigned to either an experimental group (EXP, n=32) or a control group (CONT, n=32). The experimental group underwent a 7-week adapted basketball intervention, with two 60-minute sessions per week. The control group followed standard physical education basketball sessions.

The Adapted Intervention: Fostering Inclusion and Mastery

The core of the experimental intervention lay in its didactic adaptations, meticulously designed to enhance engagement and reduce psychological barriers. The program progressed through distinct phases:

• Week 1: Familiarization: Sessions focused on introducing basic basketball rules and fundamental skills in a low-pressure environment, alternating high-intensity exercises with active recovery to manage exertion and minimize competitiveness.
• Weeks 2-3: One-on-One Drills: Defensive pressure was significantly reduced. Defenders were allowed to use only one hand and engage only after the attacker initiated movement, facilitating success and building confidence.
• Weeks 4-5: Three-on-Three Drills: The format was adjusted to 3 attackers versus 2 defenders, increasing offensive opportunities and promoting active participation.
• Weeks 6-7: Five-on-Five Games: Mandatory substitutions were implemented at each offensive transition. This ensured frequent rest periods, reduced fatigue, and allowed for continuous engagement in learning and play, thereby promoting psychological comfort and active involvement.

These adaptations were underpinned by a philosophy of promoting enjoyment, reducing anxiety, supporting emotional regulation, and optimizing basketball performance in a way that contributed to improved BMI and overall well-being. The control group, conversely, engaged in traditional basketball drills and games as per the school’s regular curriculum, without these specific modifications.

Assessment and Data Analysis

A comprehensive battery of assessments was administered pre- and post-intervention. These included:

• Body Mass Index (BMI): Measured using stadiometers and electronic scales, with calculations based on WHO guidelines.
• Emotional Eating: Assessed using the Emotional Eating subscale of the Dutch Eating Behavior Questionnaire (DEBQ).
• Sport-Related Anxiety: Evaluated using the Cognitive and Somatic Anxiety subscale of the Sport Anxiety Scale-2 (SAS-2).
• Basketball Performance: Quantified through standardized passing and shooting drills, with evaluations conducted during actual game play in the final weeks to assess practical skill application.

Statistical analysis involved two-way mixed-design ANOVAs to examine the effects of the intervention over time and between groups. Effect sizes (Cohen’s d) were calculated to interpret the magnitude of the observed changes, and Pearson’s correlation coefficients were used to explore relationships between psychological and performance variables.

Implications and Broader Impact

The findings of this study carry significant implications for physical education curricula and interventions aimed at supporting adolescent girls with obesity. The success of the didactically adapted basketball program underscores the importance of a pedagogical approach that prioritizes individual needs, emotional support, and skill development over purely competitive outcomes.

• Holistic Health Promotion: The study demonstrates that physical activity interventions can effectively address both physical and psychological health concerns simultaneously. By reducing anxiety and emotional eating, the program created a foundation for improved overall well-being, which is crucial for long-term health.
• Inclusive Education: The adaptive strategies employed in the basketball program offer a model for creating more inclusive physical education environments. By modifying traditional sports to accommodate varying abilities and psychological states, schools can ensure that all students have the opportunity to participate, learn, and thrive.
• Skill Development Beyond Sport: The observed improvements in motor skills have broader implications. Enhanced coordination, agility, and strategic thinking developed through adapted sports can translate to better cognitive function and academic performance.
• Empowerment and Self-Efficacy: The progressive success experienced by participants in the adapted program likely fostered a sense of mastery and self-efficacy, empowering them to engage more confidently in physical activity and other life challenges.

Expert Reactions and Future Directions

While direct commentary from external experts was not included in the provided text, the study’s findings align with a growing body of research emphasizing the need for person-centered, psychologically informed approaches in physical education, particularly for vulnerable populations. Educators and health professionals are increasingly recognizing that simply prescribing exercise is insufficient; the how of physical activity delivery is as critical as the what.

The authors themselves highlight several avenues for future research. Replicating the intervention across diverse cultural and socioeconomic settings is essential to assess its generalizability. Incorporating physiological and neurobiological measures would provide deeper insights into the underlying mechanisms of emotional and motor regulation. Furthermore, extending the intervention duration and exploring adaptations in other sports could offer a more comprehensive understanding of how to best support adolescent health through physical education.

Conclusion

In conclusion, this randomized controlled trial provides compelling evidence that didactically adapted basketball sessions can serve as a powerful tool in addressing the complex health challenges faced by adolescent girls with moderate obesity. By fostering a supportive, inclusive, and skill-focused environment, the program not only facilitated significant improvements in BMI and motor performance but also demonstrably reduced sport-related anxiety and emotional eating. These findings advocate for a paradigm shift in physical education, emphasizing the integration of pedagogical adaptations to create empowering and effective learning experiences that promote holistic health and well-being in all adolescents. The success of this intervention underscores the critical role of tailored physical education programs in building resilience, confidence, and healthy lifestyles for a generation at risk.
