This study investigated the effectiveness of several possible exercises for performance during standing work in order to prevent lower leg swelling and relieve subjective complaints. Volume changes in the lower leg were measured using bioelectrical impedance plethysmography in 13 healthy male subjects aged 23-36 years. Subjective complaints of leg pain, leg dullness and whole body fatigue were ...

The purpose of this study was to determine the factors that influence the co-modulation of motor unit discharge rate in soleus muscles of both legs during upright standing. Single motor units were recorded from the left and right soleus muscles under three experimental conditions: standing quietly with the eyes open and closed, standing with the eyes closed while vibration was applied to one Ac...

Background The most commonly applied therapeutic intervention is foot orthosis (insole or wedge) for arch support. However, the effect of these varies and remains controversial. Most studies were that investigated muscle activity insole application, there was no information on what kind recovery it had functionally. Purpose purpose this study to investigate transverse lower extremity kinematics...

Several studies have shown that standing up is a frequent (3-10%) trigger of loss of consciousness both in young and old subjects. An exaggerated transient BP (blood pressure) fall upon standing is the underlying cause. IOH (initial orthostatic hypotension) is defined as a transient BP decrease within 15 s after standing, >40 mmHg SBP (systolic BP) and/or >20 mmHg DBP (diastolic BP) with sympto...

Content: Electromyography (EMG) is a recording of muscles electrical activity and is useful for mechanism study. In Exercise and Sport Science, mechanism of dominance and non-dominance limb activity is recently a focus area. Objective: The aim of this study is to observe the muscle electrical activity of soccer players’ dominant and non-dominant leg. Design: Cross-sectional study. Setting: Dist...

Motor learning during reaching not only recalibrates movement but can also lead to small but consistent changes in the sense of arm position. Studies have suggested that this sensory effect may be the result of recalibration of a forward model that associates motor commands with their sensory consequences. Here we investigated whether similar perceptual changes occur in the lower limbs after le...

OBJECTIVES The purpose of this study was to examine whether field-based and/or laboratory-based assessments are valid tools for predicting key performance characteristics of skating in competitive-level female hockey players. DESIGN Cross-sectional study. METHODS Twenty-three female ice hockey players aged 15-25 years (body mass: 66.1±6.3 kg; height: 169.5±5.5 cm), with 10.6±3.2 years playi...

BACKGROUND Maintaining or improving motor (balance) ability is essential to extending the healthy lifespan of elderly people, and developing effective and efficient strategies to prevent falls of elderly people is an urgent. The purpose of this study was to determine the effects of balance exercise on fall and fracture prevention for elderly people with poor balance. METHODS A 6-month, random...

Balance disorders are very frequent in Parkinson’s disease (PD). One-leg stance performance is a predictor of fall risk. We investigated one-leg strategies people with PD. hypothesized that patients would choose, and better perform on, the leg on least affected body side. Fifty participants 2 to 19 years PD duration stood one while ON medication. The spontaneously chosen was recorded. Performan...
