The objective of this study was to evaluate ergonomic factors of the activities performed by employees of a company of seeding production. This study was conducted in a forest enterprise, located in Bom Jesus do Itabapoana, Rio de Janeiro state, Brazil. To characterize the profile of the employers, was utilized a questionnaire administered in the form of interview. The physical workload was evaluated by means of heart rate. For this analysis were made filming activities for counting of movements, thus verifying the percentage of the duration of the effort, and the position of the hand and wrist and the subjective evaluation of other factors involved .The method utilized to evaluate the risks of repetitive strain injuries while performing work activities performed at the forestry nursery was based on criteria of Moore and Garg (1995). The results exhibit that the profile found of the workers surveyed in the enterprise were: female (54.17%), incomplete primary school (45.83%), coming from rural areas (100%) married (33.3%), who does not smoke (95.83%), who consumes alcoholic beverages (54.17%). For 52% of the interviewees, the tasks are not considered highly repetitive, 90% have no work-related diseases and 90.9% often receive guidance from their supervisors. The survey of the heart rate revealed that the highest cardiovascular demands to which the worker is subjected are during the displacement from the greenhouse to the ‘shade house’ and from the ‘shade house’ to the hardening square. The study of the stance taken by the workers has identified that the activities of tubes winnowing, cutting of thinning and micro-piles are classified as a necessary corrective measures whenever possible. The evaluation of the risk of Repetitive Strain Injury found that the activities of microcuttings cutting and planting, selection (post-shipment) as high risk to the worker.
