  • Coronal as well as sagittal fascicle dynamics can bring about a gearing effect in muscle elongation by passive lengthening

    Katsuki Takahashi, Hiroto Shiotani, Pavlos E. Evangelidis, Natsuki Sado, Yasuo Kawakami

    Medicine & Science in Sports & Exercise   55 ( 11 ) 2035 - 2044  2023.11  [Refereed]

     View Summary

    ABSTRACT

    Purpose

    The amount of muscle belly elongation induced by passive lengthening is often assumed to be equal to that of fascicles. But these are different if fascicles shorter than the muscle belly rotate around their attachment sites. Such discrepancy between fascicles and muscle belly length changes can be considered as gearing. As the muscle fascicle arrangement is three-dimensional, the fascicle rotation by passive lengthening may occur in the coronal as well as the sagittal planes. Here we examined the fascicle 3D dynamics and resultant gearing during passive elongation of human medial gastrocnemius in vivo.

    Methods

    For 16 healthy adults, we reconstructed fascicles three-dimensionally using diffusion tensor imaging and evaluated the change in fascicle length and angles in the sagittal and coronal planes during passive ankle dorsiflexion (from 20° plantar flexion to 20° dorsiflexion).

    Results

    Whole muscle belly elongation during passive ankle dorsiflexion was 38% greater than the fascicle elongation. Upon passive lengthening, the fascicle angle in the sagittal plane in all regions (–5.9°) and that in the coronal plane in the middle-medial (–2.7°) and distal-medial (–4.3°) regions decreased significantly. Combining the fascicle coronal and sagittal rotation significantly increased the gearing effects in the middle-medial (+10%) and distal-medial (+23%) regions. The gearing effect by fascicle sagittal and coronal rotations corresponded to 26% of fascicle elongation, accounting for 19% of whole muscle belly elongation.

    Conclusions

    Fascicle rotation in the coronal and sagittal planes is responsible for passive gearing contributing to the whole muscle belly elongation. Passive gearing can be favorable for reducing fascicle elongation for a given muscle belly elongation.

  • Mechanical Linkage between Achilles Tendon and Plantar Fascia Accounts for Range of Motion of Human Ankle–Foot Complex

    Medicine & Science in Sports & Exercise   55 ( 1 ) 66 - 73  2023.01  [Refereed]

    Authorship:Lead author, Corresponding author

     View Summary

    Purpose The human ankle-foot complex possesses a passive range of motion (ROM) through changes in tibiocalcaneal (θcal) and foot arch (θarch) angles. Based on the anatomical linkage between the Achilles tendon (AT) and plantar fascia (PF), we hypothesized that AT and PF with different mechanical properties conjointly modulate the passive ROM of the human ankle-foot complex. We examined the association of AT and PF stiffness with passive ankle-foot ROM and further addressed differences between sexes. Methods A series of sagittal magnetic resonance images of the foot and passive ankle plantar flexion torque were obtained for 20 men and 20 women with their ankle-foot passively rotated from 30° of plantar flexion to 20° of dorsiflexion. Based on the measured changes in AT and PF lengths, θcal, θarch, and passive torque, AT and PF stiffness were determined. Results Upon passive ankle dorsiflexion, AT and PF were lengthened; their length changes were inversely correlated. Men showed a stiffer AT, more compliant PF, less calcaneal rotation, and greater foot arch deformation compared with women. Furthermore, we found inverse correlations between AT stiffness and ROM of θcal, and between PF stiffness and ROM of θarch in men and women. Conclusions Passive AT and PF extensibility counter each other. AT and PF stiffness and passive ROM of ankle-foot components were countered between sexes; however, associations between stiffness and passive ROM of the ankle-foot complex were consistent between sexes. Our findings support the notion that the balanced mechanical interaction between the AT and PF can account for the passive ROM of the human ankle-foot complex in vivo, and the differences between sexes.

  • Effect of shod and barefoot running on muscle mechanical properties

    Junya Saeki, Hiroto Shiotani, Yasuo Kawakami

    Journal of Sports Medicine and Physical Fitness   62 ( 7 ) 883 - 889  2022.07  [Refereed]

     View Summary

    BACKGROUND: Barefoot runners have a higher probability of lower leg and foot disorders compared to runners wearing traditional running shoes. However, the site of muscle stress due to barefoot running has not been reported. This study aimed to investigate the effects of shod and barefoot running on muscle mechanical properties. METHODS: Atotal of 18 healthy male subjects were included in this study and were assigned to either the shod running group or the barefoot running group. While the shod group ran on the treadmill at a speed of 75% heart rate reserve for 45 min with shoes, the barefoot group ran without shoes after warm-up session. As an index of muscle stiffness, the shear wave velocity (SWV) of the eleven lower extremity muscles were measured at rest before and after exercise using shear wave elastography. RESULTS: The tibialis posterior SWV was increased after running in the shod (3.67±0.41 m/s to 3.90±0.45 m/s) and barefoot (3.70±0.36 m/s to 4.02±0.54 m/s) groups. In contrast, the vastus lateralis SWV was increased only in the shod group (2.62±0.32 m/s to 2.80±0.34 m/s), while the peroneus muscle SWV increased only in the barefoot group (3.24±0.48 m/s to 3.50±0.55 m/s and 2.92±0.5 m/s to 3.11±0.49 m/s for the superficial and deep layers, respectively). CONCLUSIONS: The shod condition selectively influences changes in the stiffness of the vastus lateralis and peroneus muscles during running but has no effect on the tibialis posterior.

     View Summary

    <title>Abstract</title><sec>
    <title>Background</title>
    Early childhood is a transferring stage between the two accelerated growth periods (infant and adolescent). Body dimensions are related to physical growth and development. The purpose of this study was to investigate physical growth in terms of anthropometry, muscle growth of the lower extremity, and functional development over early childhood.


    </sec><sec>
    <title>Methods</title>
    A cross-sectional study was carried out on 29 preschool children (PS: 3–5 years), 21 school children (SC: 6–8 years), and 22 adults (AD: 20–35 years). Lower extremity characteristics (segmental dimensions, muscle and adipose tissue thicknesses of the thigh and lower leg), and voluntary joint torque (knee and ankle) were measured. Correlations between parameters and group comparisons were performed.


    </sec><sec>
    <title>Results</title>
    All the parameters except for body mass index (BMI) and subcutaneous adipose tissue thickness were correlated with age for PS and SC combined (<italic>r</italic> = 0.479–0.920, <italic>p</italic> &lt; 0.01). Relative thigh and shank lengths to body height were greatest in AD and smallest in PS (<italic>p</italic> &lt; 0.05) but the relative foot dimensions were significantly larger in PS and SC than in AD (<italic>p</italic> &lt; 0.05). Relative subcutaneous adipose tissue thickness was largest in PS and lowest in AD. Muscle thickness and the muscle volume measure (estimated from muscle thickness and limb length) were significantly larger in older age groups (<italic>p</italic> &lt; 0.05). All groups showed comparable muscle thickness when normalized to limb length. Joint torque normalized to estimated muscle volume was greatest for AD, followed by SC and PS (<italic>p</italic> &lt; 0.05).


    </sec><sec>
    <title>Conclusions</title>
    Relative lower extremity lengths increase with age, except for the foot dimensions. Muscle size increases with age in proportion to the limb length, while relative adiposity decreases. Torque-producing capacity is highly variable in children and rapidly develops toward adulthood. This cross-sectional study suggests that children are not a small scale version of adults, neither morphologically nor functionally.

  • Track distance runners exhibit bilateral differences in the plantar fascia stiffness

    Hiroto Shiotani, Ryo Yamashita, Tomohiro Mizokuchi, Natsuki Sado, Munekazu Naito, Yasuo Kawakami

    Scientific Reports   11 ( 1 ) 9260  2021.04  [Refereed]

    Authorship:Lead author

     View Summary

    <title>Abstract</title>Human steady-state locomotion modes are symmetrical, leading to symmetric mechanical function of human feet in general; however, track distance running in a counterclockwise direction exposes the runner’s feet to asymmetrical stress. This may induce asymmetrical adaptation in the runners’ foot arch functions, but this has not been experimentally tested. Here, we show that the plantar fascia (PF), a primary structure of the foot arch elasticity, is stiffer for the left than the right foot as a characteristic of runners, via a cross-sectional study on 10 track distance runners and 10 untrained individuals. Shear wave velocity (index of tissue stiffness: SWV) and thickness of PF and foot dimensions were compared between sides and groups. Runners showed higher PF SWV in their left (9.4 ± 1.0 m/s) than right (8.9 ± 0.9 m/s) feet, whereas untrained individuals showed no bilateral differences (8.5 ± 1.5 m/s and 8.6 ± 1.7 m/s, respectively). Additionally, runners showed higher left to right (L/R) ratio of PF SWV than untrained men (105.1% and 97.7%, respectively). PF thickness and foot dimensions were not significantly different between sides or groups. These results demonstrate stiffer PF in the left feet of runners, which may reflect adaptation to their running-specific training that involves asymmetrical mechanical loading.

  • Human plantar fascial dimensions and shear wave velocity change in vivo as a function of ankle and metatarsophalangeal joint positions

    Journal of Applied Physiology   130 ( 2 ) 390 - 399  2021.02  [Refereed]

     View Summary

    Joint angle dependence and site specificity of the plantar fascial dimensions and SWV were examined by combining sagittal magnetic resonance and supersonic shear imaging techniques. We revealed that the site-specific changes in PF SWV were related to joint angle positions, i.e., PF slackness and elasticity changed in varying combinations of ankle and MTP angle. Our findings suggest that PF can elastically support the foot arch throughout the stance phase of human bipedal locomotion.

  • Positional difference of malleoli-midpoint from three-dimensional geometric centre of rotation of ankle and its effect on ankle joint kinetics

    Gait & Posture   83   223 - 229  2021.01  [Refereed]  [International journal]

     View Summary

    BACKGROUNDS: Joint kinetic calculations are sensitive to joint centre locations. Although geometric hip and knee joint centre/axis are generally developed, the ankle joint centre (AJC) is conventionally defined as the midpoint between the malleolus lateralis and medialis (AJCMID) in most gait analyses. RESEARCH QUESTION: We examined the positional difference of the AJCMID from the geometric centre of rotation (AJCFUN) and its effect on the ankle joint kinetics in representative human gaits. METHODS: In the first experiment, we calculated the AJCFUN and indicated its location on the ankle MRI in 14 (seven male and seven female) participants. In the second experiment, we compared ankle kinematics/kinetics based on AJCFUN and AJCMID during walking and hopping at 2.6 Hz in 17 (nine male and eight female) participants. RESULTS: In both experiments, AJCFUN was located at positions significantly medial (-9.2 ± 5.4 mm and -10.1 ± 4.4 mm) and anterior (17.0 ± 7.4 mm and 15.3 ± 5.2 mm) from the AJCMID. Furthermore, the AJCMID underestimated peak dorsiflexion (AJCMID/AJCFUN: 52.6 ± 17.1%) and inversion (AJCMID/AJCFUN: 62.2 ± 11.5%) torques and their durations in walking. Additionally, AJCMID overestimated the plantar flexion torque in both gait modes [AJCMID/AJCFUN: 111.3 ± 4.8% (walking) and 112.7 ± 6.3% (hopping)]. SIGNIFICANCE: We therefore concluded that the positional difference between the geometric and landmark-based AJC definitions significantly affected ankle kinetics, thereby indicating that the functional method should be used for defining AJC for gait analysis.

  • Acute effects of long‐distance running on mechanical and morphological properties of the human plantar fascia

    Hiroto Shiotani, Tomohiro Mizokuchi, Ryo Yamashita, Munekazu Naito, Yasuo Kawakami

    Scandinavian Journal of Medicine & Science in Sports   30 ( 8 ) 1360 - 1368  2020.08  [Refereed]

    Authorship:Lead author

     View Summary

    Long-distance running (LDR) can induce transient lowering of the foot arch, which may be associated with mechanical fatigue of the plantar fascia (PF). However, this has not been experimentally tested in vivo. The purpose of this study was to test our hypothesis that LDR induces transient and site-specific changes in PF stiffness and morphology and that those changes are related to the lowering of the foot arch. Ten male recreational long-distance runners and 10 untrained men were requested to run overground for 10 km. Before and after running, shear wave velocity (SWV: an index of soft tissue stiffness) and thickness of PF at three different sites from its proximal to distal end were measured using supersonic shear imaging and B-mode ultrasonography. Foot dimensions including the navicular height were measured using a three-dimensional foot scanner. SWV at the proximal site of PF and navicular height was significantly decreased in both groups after running, with a higher degree in untrained men (−21.9% and −14.1%, respectively) than in runners (−4.0% and −6.3%, respectively). The relative change (%Δ) in SWV was positively correlated with %Δnavicular height in both groups (r =.69 and r =.65, respectively). Multiple regression analysis revealed that %ΔSWV at the proximal site solely explained 72.7% of the total variance in %Δnavicular height. It is concluded that LDR induces transient and site-specific decreases in PF stiffness. These results suggest that the majority of running-induced lowering of the foot arch is attributable to the reduction of PF stiffness at the proximal site.

  • Site- and sex-differences in morphological and mechanical properties of the plantar fascia: A supersonic shear imaging study

    Hiroto Shiotani, Ryo Yamashita, Tomohiro Mizokuchi, Munekazu Naito, Yasuo Kawakami

    Journal of Biomechanics   85   198 - 203  2019.03  [Refereed]

    Authorship:Lead author

     View Summary

    The purpose of this study was to investigate the site- and sex-differences in the morphological and mechanical properties of the plantar fascia (PF) in humans. The thickness and shear wave velocity (SWV) of PF at five different sites between the medial calcaneal tubercle and the second toe were measured for 40 healthy young participants (20 males and 20 females) using supersonic shear imaging (SSI). The thickness and SWV measurements were highly repeatable (ICC ≥ 0.93). The proximal sites of PF around the calcaneal attachment were significantly thicker and stiffer (higher SWV values) than the middle and distal sites (p < 0.05). In addition, females had significantly thinner PF in proximal and middle sites than males, while being significantly stiffer in regardless of the sites, compared with males (p < 0.05). The results of the present study partly support previous findings on the site- and sex-differences in PF morphology, and further reveal inhomogeneity and sex-specificity of PF stiffness. The present study widely opens the possibility of evaluating PF functions in vivo.

  • アキレス腱と足底腱膜の力学的特性の不均衡はランニング障害の発生機序となるか

    2023  

     View Summary

    本研究の目的は、ランナーを対象とした前向きコホート研究を実施することで、アキレス腱・足底腱膜の力学的特性についてランニング障害との関連性やトレーニングに伴う適応の様相を明らかにすることである。本年度は、測定環境の整備やMRI撮像プロトコルの作成・調整など、アキレス腱・足底腱膜の力学的特性を定量評価するためのMRI法を用いた方法論の実現に向けた取り組みを行った。また、被験者のリクルートについても大学陸上部2チームから研究協力の承諾を得た。さらに近隣の複数チームへのリクルートを進めつつ、2024年度前期からデータ取得を開始できる見込みである。

  • 疲労が足部アーチのバネ機能に及ぼす影響と身体運動パフォーマンスの関連性

    2022  

     View Summary

    本研究の目的は、人間の足部アーチ構造を支持する足部内在筋・外在筋の疲労と足部のバネ機能および身体運動パフォーマンスとの関連性を明らかにすることである。本年度は、疲労課題に伴う足部アーチの変形とMRI-T2強調画像法により定量評価した足部内在筋・外在筋の疲労度合の関連性の結果について40th Conference of theInternational Society of Biomechanics in Sportsにて発表し、査読付プロシーディングの掲載 (ISBS Proc Archive, 2022) およびNew Investigator Award (Poster) 3rdPlaceの受賞といった成果を挙げることができた。今後、足部のバネ機能の疲労に伴う変化についてさらに解析を進め、得られた結果を学術論文として発表予定である。

  • 足部・下腿軟組織の形態的・力学的特性と足部アーチのバネ機能の関連性

    2021  

     View Summary

     本研究の目的は、人間の足部・下腿に存在する軟組織の形態的・力学的特性と足部のバネ機能および身体運動パフォーマンスとの関連性を明らかにすることである。本研究助成では、MRI法や超音波法を主軸とした組織画像解析手法による軟組織の形態的・力学的特性の定量評価手法と、足部のバネ機能や身体運動パフォーマンスを定量評価する三次元動作解析手法を組み合わせた計測システムの構築を進めた。本年度は、疲労課題に伴う足部アーチの変形とMRI-T2強調画像法による足部内在筋・外在筋の疲労度合の関連性を検証した。その結果、疲労課題に伴う足部アーチの扁平化は特に後脛骨筋のT2値変化と関連することが明らかとなった。
