Influence of dynamic versus static core exercises on performance in field based fitness tests

SummaryMinimal evidence supports the claim that core stability training transfers into improved performance and the most effective training method to perform core exercises is still unknown. The purpose of the study was to compare the effects of a 6 week unstable static versus unstable dynamic core training program, on field based fitness tests. A static (n = 6) and dynamic (n = 6) training group performed two 45 min sessions per week for six weeks. Seven performance tests, consisting of three core (plank; double leg lowering; back extensions), one static (standing stork) and three dynamic (overhead medicine ball throw; vertical jump; 20 m sprint), were administered pre- and post training. Between group differences were assessed using a repeated measures MANOVA (P < 0.05). Both training groups improved in each of the core tests (P < 0.05). Neither training group demonstrated improvement in the dynamic field based tests (medicine ball throw, vertical jump height and 20 m sprint) (P > 0.05). Findings indicate that both types of training improved specific measures of core stability but did not transfer into any sport-related skill.
