Active mechanical threading by a molecular motor [PDF]

Angewandte Chemie International Edition, 2021
Molecular motors transform external energy input into directional motions and offer exquisite precision for nano-scale manipulations. In order to make full use of molecular motor capacities, their directional motions need to be transmitted and used for powering downstream molecular events – a current great challenge for molecular engineers.

Relationship Between the Practice of Physical Activity and Physical Fitness in Physical Education Students: The Integrated Regulation As a Mediating Variable

Frontiers in Psychology, 2020
The practice of physical activity (PA) contributes to the prevention of chronic diseases such as obesity, metabolic syndrome or cardiovascular diseases, being also directly related to the individual’s physical fitness.

Effect of a governmentally-led physical activity program on motor skills in young children attending child care centers: a cluster randomized controlled trial [PDF]

, 2013
OBJECTIVE: To assess the effect of a governmentally-led center based child care physical activity program (Youp'la Bouge) on child motor skills.Patients and methods: We conducted a single blinded cluster randomized controlled trial in 58 Swiss child care

Weight status and gender-related differences in motor skills and in child care : based physical activity in young children [PDF]

, 2012
: BACKGROUND: Over the last decades, a decline in motor skills and in physical activity and an increase in obesity has been observed in children. However, there is a lack of data in young children. We tested if differences in motor skills and in physical

Acute Effects of Self-Correction on Spine Deviation and Balance in Adolescent Girls with Idiopathic Scoliosis

Sensors, 2022
Background: Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of spine and trunk with a higher incidence in girls. AIS alters and reduces postural control and balance.

Speed agility trends in children according to growth: A new approach to evaluate speed agility in children

Annals of Human Biology, 2021
Background Speed agility is considered as the whole assessment of speed of movement, agility and coordination. The 10x4m test has been broadly used to evaluate physical fitness and overall health in children of developmental ages.

Motor-Free Contractility in Active Gels [PDF]

Physical Review Letters, 2020
Animal cells form contractile structures to promote various functions, from cell motility to cell division. Force generation in these structures is often due to molecular motors such as myosin that require polar substrates for their function. Here, we propose a motor-free mechanism that can generate contraction in biopolymer networks without the need ...

Attention-dependent modulation of neural activity in primary sensorimotor cortex [PDF]

, 2013
Although motor tasks at most times do not require much attention, there are findings that attention can alter neuronal activity not only in higher motor areas but also within the primary sensorimotor cortex.

Motor-cortical activity in tetraplegics [PDF]

Nature, 2001
It may eventually be feasible to reconstruct voluntary motor activity in the paralysed. Paralysed patients may benefit from the development of an implantable brain–computer interface device that can bypass damaged motor pathways1,2,3. But it is unclear whether chronically de-efferented areas will still be sufficiently excitable to respond to motor ...
