selected activities under controlled and uncontrolled conditions].

Notes: Experiments with the Max-Planck respirometer were made to
determine the energy expenditure. Four kinds of comparable tests were made under
standard conditions and ad libitum individual: walking on solid, level ground
with light clothing, in high lace boots (walking-speed 5 km/h), walking with 10
kg resp. 20 kg load on level, solid ground (running-speed 10 km). The energy
expenditure under standard conditions is much higher than in the
working-elements ad libitum speed and distance. Many persons overestimate their
personal energy expenditure which is a reason for a positive energy balance
