Hand-arm vibration caused by isolated shocks is familiar from the occupational sphere, for example during work with stud guns and pneumatic nail drivers or forging hammers. Whether the existing methods for the measurement and assessment of continuous vibration in accordance with EN ISO 5349-1  are also adequate for measuring and assessing isolated shock exposures is the subject of an ongoing research project. In order for confounding effects from the leisure sphere (e.g. tennis, golf) to be excluded, the effects of shocks were measured. With reference to the example of tennis as a leisure activity, the procedure is presented, including the preliminary studies required for isolated impact measurement, for determining the measurement points and coupling and for the elimination of artefacts. The field measurements were conducted on experienced players (test persons) in the scenarios of "serve", "return forehand" and "return backhand". The unweighted ah, the band-limited acceleration ahF and the additional frequency weighting awp were evaluated in accordance with ISO/TR 18570 in addition to the usual measurement variable of the frequency-weighted acceleration ahw. An indicative risk assessment was performed based on the existing assessment method. A health risk presented by exposure in the leisure sphere alone cannot be excluded by assessment of a typical exposure scenario.
