Echo intensity and muscle thickness as predictors Of athleticism and isometric strength in middle‐school boys

Abstract

VL and RF echo intensity and muscle thickness may help predict athleticism, and to a lesser extent, RTD, in boys. Muscle Nerve 55: 685-692, 2017.

Tongue thickness is associated with masticatory performance of perioral muscles: Ultrasonographic study of perioral muscle characteristics in healthy young subjects

“…25 The thick tongue compensates for vertical tongue movement and might be associated with efficient mastication. 15,28 Thus, a relationship between TT and masticatory performance could be expected based on the associations between tongue pressure and these factors; TT might be an effective predictor of masticatory performance. 4,26 In addition, a relationship between TT and tongue pressure has been reported in previous studies of community-dwelling elderly or patients with neuromuscular disease.…”

“…22,27 Notably, there have been no reports of a direct relationship between TT and tongue pressure in healthy young subjects; however, the association between muscle quantity and muscle strength has been demonstrated in masseter muscle and limb muscle. 15,28 Thus, a relationship between TT and masticatory performance could be expected based on the associations between tongue pressure and these factors; TT might be an effective predictor of masticatory performance.…”

“…10 A relationship between tongue thickness (TT) and tongue movement was also shown in an ultrasonic study comparing TT at rest and during bolus passage. 14,15 Tongue muscle mass was reported to be smaller and tongue echo intensity (TEI) was reported to be greater in patients with sarcopenic dysphagia than in patients without sarcopenic dysphagia. 12 An ultrasonic diagnostic apparatus can be used to evaluate muscle quantity, as well as muscle quality (ie echo intensity).…”

“…13 With respect to the limb muscles of elderly women and middle school boys, muscle quantity and quality are related to muscle strength and physical function. 14,15 Tongue muscle mass was reported to be smaller and tongue echo intensity (TEI) was reported to be greater in patients with sarcopenic dysphagia than in patients without sarcopenic dysphagia. 16 However, there have been few reports regarding the relationship between perioral muscle echo intensity and oral function (ie masticatory performance).…”

Physiological differences between advanced CrossFit athletes, recreational CrossFit participants, and physically-active adults

“…Skeletal mass and the morphological characteristics of muscle are suggestive of a greater ability to produce force [59][60][61][62]. That is, the size, architecture and quality of skeletal muscle reflect the capability of activated muscle to produce force, whereas bone mass provides the structural support and stability needed to effectively translate force production into human movement.…”
