Wilbur on the Trampoline

Trampoline Park and Home Trampoline Injuries.

BACKGROUND AND OBJECTIVE Trampoline parks, indoor recreational facilities with wall-to-wall trampolines, are increasing in number and popularity. The objective was to identify trends in emergency department visits for trampoline park injuries (TPIs) and compare TPI characteristics with home trampoline injuries (HTIs). METHODS Data on trampoline injuries from the National Electronic Injury Sur...

Wilbur is back.

Trampoline injuries.

OBJECTIVE To describe the mechanism, location and types of injury for all patients treated for trampoline-associated injuries at St Olav's University Hospital, Trondheim, Norway, from March 2001to October 2004. MATERIALS AND METHODS Patients were identified from a National Injury Surveillance System. All patients were asked to complete a standard questionnaire at their first visit at the hosp...

Modeling and inverse simulation of somersaults on the trampoline.

This paper describes a biomechanical model for numerical simulation of front and back somersaults, without twist, performed on the trampoline. The developed mathematical formulation is used to solve an inverse dynamics problem, in which the moments of muscle forces at the joints that result in a given (measured) motion are determined. The nature of the stunts and the way the human body is maneu...

The fluid trampoline: droplets bouncing on a soap film

We present the results of a combined experimental and theoretical investigation of droplets falling onto a horizontal soap film. Both static and vertically vibrated soap films are considered. In the static case, a variety of behaviours were observed, including bouncing, crossing and partial coalescence. A quasi-static description of the soap film shape yields a force–displacement relation that ...
