Background: The abdominal wall muscles can be broadly categorized into superficial (global) muscles and deep (local) muscles. Although both components work synergistically. Yoga is a widely practiced intervention that incorporates sustained postures (asanas), dynamic transitions, and isometric contractions. These elements engage both superficial and deep abdominal muscles. This study aims to assess and compare global abdominal muscle strength and core muscle stability in yoga practitioners to better understand their functional relationship.
Methods: We included 70 yoga practitioners from age 35-45 years in our observational cross-sectional study from various yoga centre and community settings. Outcome measures used for assessing core strength was manual muscle testing (MMT) through curl up performance whereas stability was check using pressure biofeedback.
Results: The sample comprised 70 yoga practitioners aged 35-45 years (mean age 40.2 years) with a female predominance (70%). The average BMI was 25.2 kg/m². Participants demonstrated higher global abdominal muscle strength (median grade 4), while core stability was moderate (median level 2).
Conclusions: Higher strength grades showing better stability performance. Therefore, assessment and training programs should include both global strengthening and specific deep core stabilization to achieve comprehensive trunk muscle function.
