Introduction. The purpose of this study was to evaluate the effects of bouldering on upper and lower limb muscle strength and body balance.
Material and Methods. The study group consisted of 22 climbers (aged 27.23 ± 4.81) with at least 2 years of bouldering experience, while the control group consisted of 20 men (aged 23.10 ± 5.28) not practicing rock climbing. The study received approval from the local bioethical commission in Poland. Static and dynamic stabilographic parameters were measured with eyes open (EO) and closed (EC) on the Biodex Balance System SD USA (BBS) platform. Subsequently, the maximum muscle torques of the elbow, hip, knee and ankle joints were measured in isometric conditions. Hand-grip strength (HGS) with and without the thumb was assessed using a handheld dynamometer.
Results. Climbers achieved significantly higher values of HGS with the thumb of both hands (p < 0.005), foot extensors strength (FES) in both limbs (p < 0.05) and left hip extensors (HES L) (p < 0.05). They also achieved significantly lower values of all stabilographic parameters, indicating better balance compared to the control group (p < 0.05). An interaction of HES x SIDE across the groups was observed (F(1,40) = 13.588, p < 0.001 η2 = 0.254). Moreover, there was a statistically significant negative correlation of ankle extensors strength with medial-lateral stability index (MLSI EC) (right: r = -0.418; left: r = -0.331) and fall risk index (FRI6-2) (right: r = -0.520; left: r = -0.435).
Conclusions. Regular climbing training develops muscle strength, especially FES, HES, HGS, and improves balance. Climbing can be used for prevention of muscle weakness and equilibrium disorders.
