Core musculature co-contraction during suspension training exercises

Area of Science:

• Exercise Physiology
• Biomechanics
• Sports Science

Background:

• Suspension training is often promoted for core strengthening.
• Core musculature co-contraction is vital for stability and performance.
• Evidence comparing suspension training to floor exercises for core co-contraction is limited.

Purpose of the Study:

• To investigate if suspension training increases core musculature co-activation compared to floor exercises.
• To compare co-contraction ratios of the rectus abdominis, erector spinae, and abdominal obliques between suspension and floor exercises.

Main Methods:

• 25 healthy volunteers performed push-ups, bridges, and prone planks.
• Wireless electromyography recorded muscle activity from rectus abdominis, erector spinae, and obliques.
• Co-contraction ratios were calculated and analyzed using paired t-tests.

Main Results:

• Core musculature co-contraction was significantly higher during all floor exercises compared to suspension trainer exercises.
• No significant difference was found in co-contraction ratios when comparing suspension training to floor exercises.

Conclusions:

• Traditional floor exercises elicit greater core muscle co-contraction than suspension training.
• Individuals may benefit from mastering floor exercises to build core stability before engaging in suspension training.
• Suspension training's instability may be too challenging for individuals with underdeveloped core control.
