This study evaluated the feasibility of using foot center of mass and hallux to determine foot strike and take-off during vertical jumps. The results showed that foot center of mass had the closest agreement with the force platform in this aspect.
Determining foot strike and take-off during vertical jumps is essential to calculate a range of performance measures, which normally requires the use of expensive equipment such as force platforms. This study evaluated whether tracking the foot centre of mass(CoM) and hallux could be suitable alternatives to determine foot strike and take-off during jumps. Thirteen recreational runners performed six unilateral jumps. Foot strike and take-off instants were observed using three algorithms from foot CoM, pelvis CoM and the hallux marker and results were compared with data determined by the force platform. Bland-Altman method and Cohen effect sizes were used to assess the differences between methods. For foot strike, the difference between the foot CoM and the force platform (12 ms, d < 0.01) was smaller than using the pelvis CoM (46 ms, d < 0.01) and similar to the hallux (16 ms, d < 0.01). For the take-off, the foot CoM produced the smallest difference (i.e., 4 ms, d < 0.01; pelvis = 22 ms, d < 0.01 and hallux = 18 ms, d < 0.01). The foot CoM seems to yield the closest agreement with the force platform when determining foot strike and take-off during vertical jumps. However, the hallux marker can be used as an alternative to the foot CoM once corrected for mean bias.
