Kinematics in lateral plyometric jumping exercise at different distances
Moody, Jeremy A.
MetadataShow full item record
Jump-based exercises, such as plyometrics, are reported to be an effective method for the development and enhancement of physical qualities in the legs, for example power and reactive strength, for change of direction movements. The purpose of the study was to examine a unilateral jump over different distances, with the aim of quantifying the changes that occur to joint displacement at the hip, knee and ankle joints, as well as changes to ground contact time (GCT). Eight healthy participants took part in the study, each of whom had previous experience of sports, which included change of direction movements. Results of a repeated measures ANOVA revealed significant differences to GCT on the right leg (P < 0.05) but not on the left (P > 0.05) as jump distance increased. For joint displacement, significant differences were observed at the right ankle and right knee but not at any other joint. The results of the study confirm that this particular activity is not suited for training to improve change of direction speed (CODS) performance. Group means and the discussion can aid practitioners in an appropriate exercise selection for training programming.
