Abstract
This report summarises the heart rate strain of six manual contract pruners working in New Zealand plantation forestry conditions. Activity sampling was used to record the subjects' work methods throughout their complete working day. Heart rate data was collected and applied to several heart rate indices in order to determine the strain of manual pruning. An average working heart rate ± standard deviation (SD) of 112 bt.min −1 ± 10.4, a mean relative heart rate of 29% + 7% (SD), a mean ratio of working heart rate to sleeping heart rate of 1.45 ± 0.1 (SD) and a mean 50% working heart rate level of 0.82 ± 0.1 (SD) all indicate that manual pruning can be classified, in terms of heart rate strain, as a moderate workload activity.
