Relationship between agility and lower limb muscle strength, targeting university badminton players.

PMID 29545704WHAT IT FOUND
In 23 male university badminton players, higher side-shuffle scores were linked to greater hip extension and ankle plantar flexion strength, after accounting for years of play.
Key findings
01Side-shuffle agility scores were correlated with badminton experience and with hip flexion, hip extension, knee flexion and ankle plantar flexion strength.
02After adjusting for badminton experience, agility scores were still correlated with hip extension strength and ankle plantar flexion strength.
03Knee extension and ankle dorsal flexion strength did not show significant correlations with agility in the analyses.

What it does not show
Only 23 male university badminton players without lower-limb pain were studied, so the results may not apply to female players, injured players, or players in other sports. The study only measured correlations, so it cannot show that hip extension or ankle plantar flexion strength causes better agility. The authors state it was unknown when the muscles contributed to agility during the side-shuffle test. The study did not test strength training, and the authors say an intervention study is needed to show whether training develops agility.
Declared interests
The authors declared no conflicts of interest.
The easy way to misread this
Do not conclude that hip extension or ankle plantar flexion strength training will improve agility. This study only measured associations in 23 male university badminton players, and the authors say an intervention study is needed.
