  text: "<jats:title>Abstract</jats:title>\r\n          <jats:p>Random fluctuations
    in somatosensory signals affect the ability of effectively coordinating multimodal
    information pertaining to the postural state during movement. Therefore, this
    study aimed to investigate the impact of a compliant surface on cortico-cortical
    causal information flow during multi-joint compound movements. Fifteen healthy
    adults (7 female / 8 male, 25.9 ± 4.0 years) performed 5 × 20 repetitions of bodyweight
    squats on firm and compliant surface. Motor behavior was quantified by center
    of pressure (CoP) displacements, hip movement and the root mean square of the
    rectus femoris activity. Using source space analysis, renormalized partial directed
    coherence (rPDC) computed subject-level multivariate effective brain connectivity
    of sensorimotor nodes. Bootstrap statistics revealed significantly decreased medio-lateral
    CoP displacement (<jats:italic>p</jats:italic> &lt; 0.001), significantly increased
    velocity of medio-lateral hip motion (<jats:italic>p</jats:italic> &lt; 0.001)
    as well as significantly lower rectus femoris activity (<jats:italic>p</jats:italic> &lt; 0.01)
    in the compliant surface condition. On the cortical level, rPDC showed significantly
    modulated information flow in theta and beta frequencies for fronto-parietal edges
    (<jats:italic>p</jats:italic> &lt; 0.01) only during the concentric phase of the
    movement. The compliant surface led to increased difficulties controlling hip
    but not center of pressure motion in the medio-lateral plane. Moreover, a decreased
    activation of the prime movers accompanied by modulations of effective brain connectivity
    among fronto-central nodes may point to altered demands on sensorimotor information
    processing in presence of sensory noise when performing bodyweight squats on compliant
    surface. Further studies are needed to evaluate a potential benefit for athletic
    and clinical populations.</jats:p>"

  text: <jats:title>Abstract</jats:title><jats:p>Coordinative challenging exercises
    in changing environments referred to as open-skill exercises seem to be beneficial
    on cognitive function. Although electroencephalographic research allows to investigate
    changes in cortical processing during movement, information about cortical dynamics
    during open-skill exercise is lacking. Therefore, the present study examines frontal
    brain activation during table tennis as an open-skill exercise compared to cycling
    exercise and a cognitive task. 21 healthy young adults conducted three blocks
    of table tennis, cycling and n-back task. Throughout the experiment, cortical
    activity was measured using 64-channel EEG system connected to a wireless amplifier.
    Cortical activity was analyzed calculating theta power (4–7.5 Hz) in frontocentral
    clusters revealed from independent component analysis. Repeated measures ANOVA
    was used to identify within subject differences between conditions (table tennis,
    cycling, n-back; <jats:italic>p</jats:italic> &lt; .05). ANOVA revealed main-effects
    of condition on theta power in frontal (<jats:italic>p</jats:italic> &lt; .01,
    <jats:italic>η</jats:italic><jats:sub>p</jats:sub><jats:sup>2</jats:sup> = 0.35)
    and frontocentral (<jats:italic>p</jats:italic> &lt; .01, <jats:italic>η</jats:italic><jats:sub>p</jats:sub><jats:sup>2</jats:sup> = 0.39)
    brain areas. Post-hoc tests revealed increased theta power in table tennis compared
    to cycling in frontal brain areas (<jats:italic>p</jats:italic> &lt; .05, <jats:italic>d</jats:italic> = 1.42).
    In frontocentral brain areas, theta power was significant higher in table tennis
    compared to cycling (<jats:italic>p</jats:italic> &lt; .01, <jats:italic>d</jats:italic> = 1.03)
    and table tennis compared to the cognitive task (<jats:italic>p</jats:italic> &lt; .01,
    <jats:italic>d</jats:italic> = 1.06). Increases in theta power during continuous
    table tennis may reflect the increased demands in perception and processing of
    environmental stimuli during open-skill exercise. This study provides important
    insights that support the beneficial effect of open-skill exercise on brain function
    and suggest that using open-skill exercise may serve as an intervention to induce
    activation of the frontal cortex.</jats:p>
