Anatomical and biomechanical traits of broiler chickens across ontogeny. Part II. Body segment inertial properties and muscle architecture of the pelvic limb [PDF]

, 2014
In broiler chickens, genetic success for desired production traits is often shadowed by welfare concerns related to musculoskeletal health. Whilst these concerns are clear, a viable solution is still elusive.

Human gastrocnemius medialis Pennation Angle as a Function of Age: From Newborn to the Elderly.

Journal of PHYSIOLOGICAL ANTHROPOLOGY and Applied Human Science, 2001
The aim of the present study was to quantify changes in human skeletal muscle pennation angle (F theta) values during growth and adult life. The human gastrocnemius medialis muscle of 162 subjects (96 males and 66 females) in the age range 0-70 years was scanned with ultrasonography. The subjects were laying prone, at rest, with the ankle maintained at

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

Journal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths

Ontogenetic scaling patterns and functional anatomy of the pelvic limb musculature in emus (Dromaius novaehollandiae) [PDF]

, 2014
Emus (Dromaius novaehollandiae) are exclusively terrestrial, bipedal and cursorial ratites with some similar biomechanical characteristics to humans. Their growth rates are impressive, as their body mass increases eighty-fold from hatching to adulthood ...

Change in Gastrocnemius Pennation Angle According to Ankle Dorsiflexion among University Students

Journal of the Korea Academia-Industrial cooperation Society, 2015
본 연구의 목적은 발목관절의 발등굽힘 각도를 $0^{\circ}$ , $10^{\circ}$ , $20^{\circ}$ 로 위치하게 한 후 각 각도에서 장딴지근의 깃각 변화에 미치는 영향을 비교하여 효율적인 장딴지근 신장 각도를 제시하는 것이다. 건강한 성인 남녀 25명을 그 대상으로 하여 발목관절 발등굽힘 각도 $0^{\circ}$ , $10^{\circ}$ , $20^{\circ}$ 에서 초음파 기기를 이용하여 내측 장딴지근의 깃각을 측정하였다. 각도별 장딴지근의 깃각 변화를 알아보기 위해 반복측정분산분석을 성별에 따른 각도별 차이를 알아보기 위해 독립 t 검정을 실시하였다.

Cross‐education of lower limb muscle strength following resistance exercise training in males and females: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract Cross‐education describes the training of one limb that leads to performance enhancements in the contralateral untrained limb, driven by neural changes rather than muscle adaptation. In this systematic review and meta‐analysis, we aimed to evaluate the efficacy of cross‐education (vs. a control group) via resistance exercise training (RET) for

The effects of static stretching programs on muscle strength and muscle architecture of the medial gastrocnemius.

PLoS ONE, 2020
IntroductionStatic stretching (SS) program are widely used in clinical and athletic settings. Many previous studies investigate the effect of SS program on muscle strength and muscle architecture (muscle thickness, and pennation angleh).

Dynamic muscle quality of the plantar flexors is impaired in claudicant patients with peripheral arterial disease and associated with poorer walking endurance [PDF]

, 2015
Objective Peripheral arterial disease and intermittent claudication (PAD-IC) negatively affects physical activity and function. There is evidence for plantarflexor muscle dysfunction and weakness; however, the extent to which this dysfunction can be ...

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...
