Wearable Sensor Analysis of Movement Biomechanics and Lateralization in Dart Throwing

In darts, the dominant limb typically has an advantage due to its superior performance characteristics. However, with training, the non-dominant limb can achieve nearly similar accuracy. Research suggests that left-handed individuals tend to have more balanced dexterity between their hands compared to right-handed individuals, who show a stronger preference for their dominant hand. This may provide a slight advantage for left-handed players. This study analyzed 12 participants (male and female, aged 20–25 years), including one left-handed male and one left-handed female, with the rest being right-handed. Each participant completed 18 throws with both their dominant and non- dominant limbs. The data collection was conducted using the XSENS MVN Awinda motion capture system, which employs inertial sensors placed on the hand, forearm, upper arm, and shoulder of both limbs. The MT Manager software extracted values such as angular variation, acceleration, and angular velocity, ensuring precise and synchronized data for analysis. The results showed higher scores and shorter throw durations when using the dominant hand. The male participants scored higher with both the dominant and non-dominant limb. The left-handed female showed greater dexterity balance between both limbs and the left-handed male showed better coordination, supporting the idea that left-handed individuals may have a natural advantage in dexterity symmetry.
