“…The stability of spine, shoulder girdle, and pelvic girdle is established before execution of a postural task by a central mechanism of anticipatory postural adjustments (11), which occur independently from the respiratory activity of the diaphragm. Proper stabilization is critical for all dynamic activities ranging from simple functional tasks to skilled athletic maneuvers (32). Moreover, some studies suggest that coactivation between the diaphragm, abdominal muscles, and pelvic floor musculature is necessary to create the sensorimotor control that is of great clinical importance and is often lacking in conditions such as vertebrogenic disorders (12,22).…”

The aim was to describe diaphragmatic behavior during postural limb activities and examine the ventilatory and stabilizing functions of the diaphragm. Thirty healthy subjects were examined in the supine position using a dynamic MRI system assessed simultaneously with specialized spirometric readings. The diaphragmatic excursions (DEs) were measured at three diaphragmatic points in the sagittal plane; the diaphragm positions (DPs) as related to a reference horizontal baseline were determined. Measurements were taken during tidal breathing (TB) and isometric flexion of upper or lower extremities against external resistance together with TB. Mean DE in both upper and lower postural limb activities was greater compared with the TB condition (P < 0.05), with the effect greater for lower limb activities. Inspiratory DPs in the upper and lower extremity activities were lower compared with TB alone (P < 0.01). Expiratory DP was lower only for lower extremity activities (P < 0.01). DP was most affected at the apex of the crescent and crural (posterior) portion of the diaphragm. DEs correlated strongly with tidal volume (Vt) in all conditions. Changes in DEs relative to the initial value were minimal for upper and lower extremities but were related to lower values of Vt (P < 0.03). Significant involvement of the diaphragm in the limb postural activities was found. Resulting DEs and DPs differed from the TB conditions, especially in lower extremity activities. The differences between the percent changes of DEs vs. Vt found for lower extremity activities were confirmed by both ventilatory and postural diaphragm recruitment in response to postural demands.

“…Generally, core stability comprises the lumbopelvic-hip complex and is the capacity to maintain equilibrium of the vertebral column within its physiologic limits by reducing displacement from perturbations and maintaining structural integrity. 2,43,49,51,54,63 Clinically and practically, this definition lacks a tangible, functional perspective that translates into principles for practical application of core stability assessment and training in active, athletic populations. Several authors have proposed a more functional perspective to describe the core as the foundation of the kinetic chain responsible for facilitating the transfer of torque and momentum between the lower and upper extremities for gross motor tasks of daily living, exercise, and sport.…”

Core Stability Training for Injury Prevention

Context:Enhancing core stability through exercise is common to musculoskeletal injury prevention programs. Definitive evidence demonstrating an association between core instability and injury is lacking; however, multifaceted prevention programs including core stabilization exercises appear to be effective at reducing lower extremity injury rates.Evidence Acquisition:PubMed was searched for epidemiologic, biomechanic, and clinical studies of core stability for injury prevention (keywords: “core OR trunk” AND “training OR prevention OR exercise OR rehabilitation” AND “risk OR prevalence”) published between January 1980 and October 2012. Articles with relevance to core stability risk factors, assessment, and training were reviewed. Relevant sources from articles were also retrieved and reviewed.Results:Stabilizer, mobilizer, and load transfer core muscles assist in understanding injury risk, assessing core muscle function, and developing injury prevention programs. Moderate evidence of alterations in core muscle recruitment and injury risk exists. Assessment tools to identify deficits in volitional muscle contraction, isometric muscle endurance, stabilization, and movement patterns are available. Exercise programs to improve core stability should focus on muscle activation, neuromuscular control, static stabilization, and dynamic stability.Conclusion:Core stabilization relies on instantaneous integration among passive, active, and neural control subsystems. Core muscles are often categorized functionally on the basis of stabilizing or mobilizing roles. Neuromuscular control is critical in coordinating this complex system for dynamic stabilization. Comprehensive assessment and training require a multifaceted approach to address core muscle strength, endurance, and recruitment requirements for functional demands associated with daily activities, exercise, and sport.

“…Ergebnisse der vorliegenden Untersuchung zeigen, dass eine detaillierte Analyse der muskulären Leistungsfähigkeit der Muskulatur von Halswirbelsäule und Lendenwirbelsäule wertvolle Ergebnisse zur individuellen Kraftleistungsfähigkeit und zu myogenen Balancen in jeder Sportart liefert. Wie bereits vorliegende Studien aufzeigen konnten, kommt unter sportmedizinischen Aspekten präventiven Trainingsprogrammen zur Kräftigung und Stabilisierung der Rumpfmuskulatur im Sport wesentliche Bedeutung zu[24][25][26]. Individualisierte Trainingsprogramme, die auf diesen Testergebnissen aufbauen, sollten fester Bestandteil im Sportbereich sein.…”
