Cortical activation during balancing on a balance board

Human Movement Science, 2017
Keeping one's balance is a complex motor task which requires the integration and processing of different sensory information. For this, higher cortical processes are essential. However, in the past research dedicated to the brain's involvement in balance control has predominantly used virtual reality paradigms whilst little is known about cortical ...

Physical Activity, Fat Balance, and Energy Balance

International Journal of Sport Nutrition, 1996
In this paper, we review the impact of physical activity on energy and maeronutrient balances. Stability of body weight and body composition depends on reaching a steady-state where the amount and composition of energy ingested are equal to the amount and composition of energy expended.

Active balancer with electromagnetic release of balancing members

31st Annual Conference of IEEE Industrial Electronics Society, 2005. IECON 2005., 2005
Active balancers are attractive to be used in applications where rotational imbalance is frequently varied. For example, in media level servo track writers used in hard disk drive industry, a set of blank disks is loaded on spindle motor for purpose of servo writing.

Balance compensation study of electromagnetic active balancer for motorized spindle

2016 13th International Conference on Ubiquitous Robots and Ambient Intelligence (URAI), 2016
With the increase of rotating speed, the rotor unbalance of the modern rotating machinery becomes more sensitive. The on-line active balance is an ideal balancing mode for precision machines. Electromagnetic balancer is a non-contact new-structure balancing device in the on-line balancing field, as it can reliably work in high-speed condition and keep ...

Body Balance Activity and Perception

Perceptual and Motor Skills, 1963
Thirty-five Ss were tested on a specially constructed force platform for body balance activity resulting from visual perceptions of 10 simple line drawings. No relationship was found between direction of movement on the platform and the direction depicted by the line drawings.

Balancing immune activation with Itk

Trends in Pharmacological Sciences
Development of protective immune responses relies on a balance between proinflammatory CD4 T helper (Th) cell populations such as Th17 cells and regulatory CD4 T cells (Tregs) that keep immune activation in check. Evidence that interleukin-2-inducible T cell kinase (Itk) regulates this balance supports therapeutic applications for Itk inhibition.
