27 lut 2024 · Static Push Force - Maximal static push forces for adult males are shown in Figure 4.9.3-6. While these data were collected in a 1-G situation, the fact that they do not depend on friction resulting from body weight makes them applicable to microgravity.

There are three basic categories of strength: Static strength (isometric strength), which is steady force exerted while the limbs are in a stationary or static position. Dynamic strength, which is a force exerted by limbs moving in a smooth manner over time, such as while lifting an object.
Tables 1 and 2 contain the upper force limits for a variety of pushing and pulling tasks. They indicate the amount of force that a worker should exert. It is important to be aware that the forces in the tables are not the same as the weight of objects being pushed and pulled.
Most of the scientific studies on pushing and pulling have utilized psychophysics, either maximum isometric or isokinetic pushing and pulling strengths for a single exertion or maximum acceptable pushing and pulling forces for repetitive pushing and pulling.
1 mar 2017 · Pushing also resulted in lower vertical off-axis forces averaging 32% of the required on-axis force (pulling: 53%) [29]. Pull exertions also induced up to twice as much LCF as pushing, regardless of handle height and hand forces [10] .
The greatest pull strength of 400 Newtons (N) for males was recorded in the seated and standing positions. Females pull strengths in the seated and standing positions were 222 and 244 N, respectively. The strongest push strength was always at the maximum reach at the overhead location.
