Network Meta-analysis of Combined Strength and Power Training for Countermovement Jump Height

Int J Sports Med DOI: 10.1055/a-2105-0540Combined strength and power training in a training program is considered to
improve the vertical jump, which is frequently quantified using the
countermovement jump height. It is not yet clear whether one of the different
training set structures, such as complex training, contrast training, compound
training and traditional training, is superior to another. The aim of this
review is to describe and assess the comparative effects of the set structures
on countermovement jump height in healthy subjects. A systematic review and
network meta-analysis (NMA) was conducted in accordance with Preferred Reporting
Items for Systematic Reviews and Meta-Analyses for Network Meta-Analyses. Three
databases were systematically searched. Risk of bias was assessed using the Risk
of Bias 2 tool. NMAs were performed using a random-effects model. Twenty-four
studies were included. All interventions were superior to control (no
intervention) with mean differences ranging from 2.87 [95% confidence
interval (CI): 1.99 to 3.74] for complex training to 3.43 (95% CI: 2.61
to 4.26) for traditional training. None of the training interventions were
superior compared to each other in strength and/or power trained
subjects, as well as in non-strength and/or power trained subjects. The
findings supp...
