The influence of horizontal whole-body vibration of fairly low intensity alone and combined with the mental load and motor action typical for the forest machine drive on heart rate variability (HRV), respiration rate (RR) and heart rate (HR) was studied by testing five subjects. Horizontal vibration had an influence on HR, HRV and RR. ’Control activities’ had the most influence on RR and HRV, but some influence on HR, too. ’Moving the control devices’ (motor action) gave the same response in HR as ’control activities’, but not in HRV and RR. ’Control activities’ together with ’vibration’ had a more effect on HRV and RR than these two factors singly, but not on HR. The possibilities of using these variables in field studies are discussed.

Energy intake of ten lumberjacks in Eastern Finland was estimated by using 24-hour recall. In addition, serum cholesterol and triglycerides were analysed in different lipoprotein fractions. Average energy intake was according to present recommendations in Finland, although there was great individual variation. Serum triglycerides were in the normal range. Five lumberjacks’ total cholesterol concentration was somewhat increased. Average HDL concentration was clearly greater than in men of the same age.

Alongside the extent of forest production, the demand for labour input in forestry depends on the development of the structure of production and of the productivity of the work. In this, mechanization of harvesting will have long-lasting influence. Despite the growth in forestry production, the number of forestry workers has decreased considerably in many countries, but at the same time the share of professional forest workers has increased. The permanence of work fundamentally affects the life of a forest worker. It has influence on the income level, on the social position of the worker and on the standard of living.
The appreciation of the occupation of a forest worker will be increased mainly within the increasing mechanization of the work. It requires vocational training, and it will improve wages, competition of skilled workers and social appreciation of the vocation. In order to influence their benefits forest workers have organized themselves into trade unions. They activate their members in to helping the unions to attain their aims. Trade unions try to influence the policies of forestry and forest labour. In this respect they are in contact with political parties. The questions of labour policy occupy a central position in the mutual relations of the labour market organizations. Within mutual cooperation much promotion has been achieved concerning wages, working conditions, rationalization, improvement of housing facilities and other living conditions. Especially in some East-European countries attention is being paid to the motivation of forest workers.

The remote areas of Eastern and Northern Finland are mostly owned by the state. Forestry in these areas has been mainly managed by arranging temporary lodgings for the forest workers. A report on the suitability of forest worker villages as a more permanent solution to the accommodation problem was commissioned from forest officer Oiva Suominen.
Seasonal work, arduousness of the work and distance from home have decreased the attractivity of forest work as a profession. On the other hand, forestry has provided rural population work during winter, when there is little work in agriculture. To be able to increase permanent labour in state forestry, it is necessary to arrange permanent lodging to the workers and their families. Permanent workforce is needed to arrange wood harvesting and manage the state forests effectively. The article includes a suggestion of how to establish the forest worker villages. It suggests the locations and sizes for villages for the districts of Eastern Finland, Ostrobothnia and Perä-Pohjola.

Due to constantly changing working sites often in remote places the working conditions of forest workers and log floaters have been inadequate. The article discusses the requirements of the act on the housing of forest workers and log floaters that came into force in 1928, and assesses how it affected the working conditions of the laborers.
The employers had positive attitude towards the new legislation and they had improved the housing conditions to match the requirements. Most complaints in the inspections of the working conditions were found in Eastern Finland. The shortages were considered to be mostly minor ones. Even if the act concerned only housing, it improved indirectly also nourishment in the working sites. Other factors affecting the working conditions were shelters for the draught horses, health care, and newspapers and other spare-time activities available for the workers.

The aim of the study was to search for measurement methods of muscle fatigue in forest work. Lactic acid concentration of capillary blood was measured from test persons after submaximal and maximal strain tests in laboratory and during forest work. At rest the lactic acid content was affected mainly by the body dimensions and blood pressure. In a maximal strain test it was affected mainly by the age. In submaximal forest work lactic acid content concentrated below the attitude factor indicating working pace and below the body dimensions so that bigger persons had a higher lactic acid concentration than smaller persons.
