Purpose: The aim of this study was to compare the center of pressure (COP) displacement and vertical ground reaction force(VGRF) of forward versus side lunges with different arm positions.
Methods: Twenty-one healthy adults participated in the study. The area and velocity of COP and mean and peak VGRF weremeasured using a force plate during static forward lunges with arms raised (SFL-AR), static forward lunges with hands on hips(SFL-HH), static side lunges with arms raised (SSL-AR), and static side lunges with hands on hips (SSL-HH). All participantsperformed seven repetitions of each type of lunge, and measurements for the middle five repetitions were included in the data analysis.
Results: The area, path length, velocity, and deviation X of the COP were significantly higher for the SSL-AR than for theSFL-AR and SFL-HH groups (p ˂ .01). Additionally, the area, path length, velocity, and deviation X of the COP were significantlyhigher for the SSL-HH group than for the SFL-AR and SFL-HH groups (p ˂ .01). The normalized mean GRF and normalizedpeak GRF were significantly higher during SSL-AR than during SFL-HH (p ˂ .01). Moreover, the normalized mean andnormalized peak GRF were significantly higher during SSL-HH than during SFL-AR and SFL-HH (p ˂ .01).
Conclusion: Static side lunges are more dynamic and faster than static forward lunges. Furthermore, static side lungesrequire greater weight bearing than static forward lunges. These findings suggest that static forward lunges should beimplemented before static side lunges when performing dynamic balance training and closed-chain rehabilitation of thelower extremities.
