A boxing-oriented exercise intervention for obese adolescent males: findings from a pilot study

Area of Science:

• Exercise Science
• Public Health
• Adolescent Health

Background:

• Obese Māori and Pasifika adolescents face significant cardio-metabolic risks.
• Increased physical activity is a proposed intervention strategy for this demographic.
• Non-contact boxing training is explored as a novel approach to improve health outcomes.

Purpose of the Study:

• To investigate the effects of a 12-week non-contact boxing-oriented training program on cardio-metabolic variables in obese Māori and Pasifika adolescent boys.
• To explore participant and parent motivation and experiences related to the intervention.

Main Methods:

• A mixed-method design was employed, including physiological measurements and focus group interviews.
• Participants (n=3) engaged in 12 weeks of 3x weekly 60-minute sessions (30 min boxing, 30 min resistance training).
• Measured variables included anthropometrics, visceral fat thickness, central blood pressures, and arterial stiffness (AIx, β).

Main Results:

• No significant changes in body weight or BMI were observed.
• A moderate decrease in visceral fat thickness (d=0.36) and a small improvement in carotid arterial stiffness (β, d=0.18) were noted.
• Qualitative data indicated positive participant experiences including new friendships, improved appearance, and increased fitness, alongside parental reports of enhanced self-confidence and school performance.

Conclusions:

• The boxing-oriented program demonstrated motivational benefits and some positive physiological effects for obese adolescent boys of Māori and Pasifika descent.
• Poor recruitment rates underscore the need to identify and overcome barriers to engagement in physical activity interventions.
• Future research should focus on developing strategies to enhance recruitment and sustained participation in exercise programs for this population.
