Change in knee contact force with simulated change in body weight

Measurement of Change in Body-weight.

In clinical practice and in metabolic research, it is often necessary to determine whether body-weight has changed, and if so by how much, during the period of observation. Unless the changes are gross, single measurements at the beginning and the end of the period may be misleading because the trend of weight is obscured by rapid fluctuations from day to day. 'These fluctuations may be quite l...

Neuromuscular adaptations associated with knee joint angle-specific force change.

PURPOSE Neuromuscular adaptations to joint angle-specific force increases after isometric training have not yet been fully elucidated. This study examined angle-specific neuromuscular adaptations in response to isometric knee extension training at short (SL, joint angle 38.1° ± 3.7°) versus long (LL, 87.5° ± 6.0°) muscle lengths. METHODS Sixteen men trained three times a week for 6 wk either ...

The Dynamics of Human Body Weight Change

An imbalance between energy intake and energy expenditure will lead to a change in body weight (mass) and body composition (fat and lean masses). A quantitative understanding of the processes involved, which currently remains lacking, will be useful in determining the etiology and treatment of obesity and other conditions resulting from prolonged energy imbalance. Here, we show that a mathemati...

Social Stress at Work and Change in Women’s Body Weight

Social stressors at work (such as conflict or animosities) imply disrespect or a lack of appreciation and thus a threat to self. Stress induced by this offence to self might result, over time, in a change in body weight. The current study investigated the impact of changing working conditions--specifically social stressors, demands, and control at work--on women's change in weighted Body-Mass-I...
