Study designs of evaluations included in the review
Studies using a control group were eligible for inclusion. There was insufficient information in the review to determine the exact design of the included studies.
Specific interventions included in the review
Studies of WBV used for repeated periods over at least 1 week were eligible for inclusion. Vibration parameters varied between the studies. The length of sessions ranged from 4 to 30 minutes and the majority of sessions were conducted three times a week (range: 2 to 5). Study duration ranged from 9 days to 8 months. In the majority of studies, the participants carried out body-loaded static and dynamic exercises whilst using the platform. In other studies the participants performed squats or static standing. Control groups either performed identical exercises or strength training, or were a passive control group.
Participants included in the review
Inclusion criteria for the participants were not stated. The majority of studies were of young mixed- or single-sex groups with a mean age ranging from 19.9 to 25.5 years. Three studies were of postmenopausal women with a mean age ranging from 60.7 to 64.6 years. The participants varied in their level of fitness.
Outcomes assessed in the review
Studies of the effects on muscle strength and/or jump performance were eligible for inclusion. The outcomes reported in the included studies were unilateral or bilateral isometric leg press, countermovement jump, grip strength, isometric and isokinetic unilateral knee extension and flexion strength, squat jump and squat.
How were decisions on the relevance of primary studies made?
