“…• Rectus femoris was assessed in supine position in full extension [65,68,72,[76][77][78][79][80][81][82][83][84][85][86], with knees at 10° [87][88][89], in semi-Fowler position [90][91][92]. It was assessed in sitting position with hips and knees at 90° [66,93] and with hips at 90° and knees at 60° [94].…”

“…At a two-third distance between the greater trochanter and the lateral condyle, rectus femoris was assessed for muscle thickness [67]. Vastus lateralis was assessed for muscle thickness [86], cross-sectional area [86], fascicle length [86], pennation angle [86] and echo intensity [86].…”

“…Regarding dominant/nondominant side, there is some discussion about the relevance of functional asymmetry and strength differences in dominant versus non-dominant side [153]. In non-athletic populations, inter-limb differences in strength are possibly more related to neural factors than pure muscle-related factors [86]. Since this is not clear in literature, it is advised to clearly indicate whether the dominant or non-dominant side is assessed.…”

“…To be complete, there could be other reasons to choose for a different measurement site in specific muscles. Ticinesi et al [86] suggested to use the distal point of 65% of the length of the vastus lateralis, as this site is most free of vessels and muscle biopsies can be easily made, avoiding major vessels and nerves. However, without specific arguments for clinical correlates, this is not recommended.…”

Purpose Measurement of muscle mass is paramount in the screening and diagnosis of sarcopenia. Besides muscle quantity however, also quality assessment is important. Ultrasonography (US) has the advantage over dual-energy X-ray absorptiometry (DEXA) and bio-impedance analysis (BIA) to give both quantitative and qualitative information on muscle. However, before its use in clinical practice, several methodological aspects still need to be addressed. Both standardization in measurement techniques and the availability of reference values are currently lacking. This review aims to provide an evidence-based standardization of assessing appendicular muscle with the use of US. Methods A systematic review was performed for ultrasonography to assess muscle in older people. Pubmed, SCOPUS and Web of Sciences were searched. All articles regarding the use of US in assessing appendicular muscle were used. Description of US-specific parameters and localization of the measurement were retrieved. Results Through this process, five items of muscle assessment were identified in the evaluated articles: thickness, crosssectional area, echogenicity, fascicle length and pennation angle. Different techniques for measurement and location of measurement used were noted, as also the different muscles in which this was evaluated. Then, a translation for a clinical setting in a standardized way was proposed. Conclusions The results of this review provide thus an evidence base for an ultrasound protocol in the assessment of skeletal muscle. This standardization of measurements is the first step in creating conditions to further test the applicability of US for use on a large scale as a routine assessment and follow-up tool for appendicular muscle.

Exercise training effectively mitigates aging-induced health and fitness impairments. Traditional training recommendations for the elderly focus separately on relevant physiological fitness domains, such as balance, flexibility, strength and endurance. Thus, a more holistic and functional training framework is needed. The proposed agility training concept integratively tackles spatial orientation, stop and go, balance and strength. The presented protocol aims at introducing a two-armed, one-year randomized controlled trial, evaluating the effects of this concept on neuromuscular, cardiovascular, cognitive and psychosocial health outcomes in healthy older adults. Eighty-five participants were enrolled in this ongoing trial. Seventy-nine participants completed baseline testing and were block-randomized to the agility training group or the inactive control group. All participants undergo pre- and post-testing with interim assessment after six months. The intervention group currently receives supervised, group-based agility training twice a week over one year, with progressively demanding perceptual, cognitive and physical exercises. Knee extension strength, reactive balance, dual task gait speed and the Agility Challenge for the Elderly (ACE) serve as primary endpoints and neuromuscular, cognitive, cardiovascular, and psychosocial meassures serve as surrogate secondary outcomes. Our protocol promotes a comprehensive exercise training concept for older adults, that might facilitate stakeholders in health and exercise to stimulate relevant health outcomes without relying on excessively time-consuming physical activity recommendations.

BackgroundThe assessment of muscle quality is expected to help predict the prognosis of sarcopenia and examine the response to intervention. Ultrasonography can be used to evaluate approaches for determining muscle quantity and quality. We focused on the lower leg muscles and examined the relationship between the ultrasonographic assessments and the components of sarcopenia and muscle quality by comparing them with those of the quadriceps muscle (QFM).Methods47 physically healthy older participants aged 78.3 ± 6.0 years (53% male) were enrolled in this cross‐sectional study. Muscle thickness (MT) and echo intensity (EI) of the lower leg muscles and QFM were assessed with ultrasonography. Muscle mass, grip strength, and gait speed, and lower leg muscle strength were measured. Muscle quality was calculated using a formula: leg muscle strength/leg muscle mass.ResultsThe MTs and EIs of the tibialis anterior muscle (TA) and QFM were significantly associated with grip and leg strength. We observed a significant correlation in the MTs and EIs of the lower leg muscles and QFM. The EIs of the lower leg muscles and QFM showed significant negative correlations with muscle quality. In the multiple linear regression model, the EI of the TA and QFM was extracted as an independent factor of muscle quality (TA: β = −0.35, p = 0.0358; QFM: β = −0.30, p = 0.0327).ConclusionsThe ultrasonographic assessments of the lower leg muscles, especially the TA, were associated with sarcopenia components and muscle quality equal to or greater than those of the QFM.
