  • Interlimb and Intralimb Coordination of Rectus Femoris and Biceps Femoris Muscles at Different Running Speeds

    Gaku Kakehata, Yuta Goto, Hikaru Yokoyama, Shigeo Iso, Kazuyuki Kanosue

    Medicine and science in sports and exercise   55 ( 5 ) 945 - 956  2023.05  [Refereed]

     View Summary

    PURPOSE: The purpose of this study was to investigate the relationship between spatiotemporal variables and the muscle activity of the rectus femoris (RF) and biceps femoris (BF) in both legs at various running speeds. METHODS: Eighteen well-trained male athletes (age: 20.7 ± 1.8 yr) were asked to run for 50 m with 7 different "subjective efforts (SE)" (20%, 40%, 60%, 80%, 90%, 95%, and 100% SE). SE scaled relative to the maximal effort running (100%). The spatiotemporal variables (running speed, step frequency, step length) were measured over the distance from 30 to 50 m. The RF and BF muscle activities were obtained from both legs with wireless electromyography (EMG) sensors. We calculated RF and BF onset/offset timings in both legs (e.g., ipsilateral leg RF is "iRF," contralateral leg BF is "cBF"), which were expressed as % of a running cycle. Based on those timings, we obtained the EMG timing variables (%), as Switch1 (iBF offset to iRF onset), Switch2 (iRF offset to iBF onset), Scissors1 (cBF onset to iRF onset), and Scissors2 (iRF offset to cBF offset). RESULTS: running speed was well correlated with the SE, and higher running speed (>9 m·s -1 ) was achieved with higher step frequency (>4.0 Hz). Relative timings of RF and BF onset/offset (%) appeared earlier and later, respectively, with an increase in running speed. The absolute duration of RF activation (s) was elongated with the decrease in absolute running cycle time (increase in running speed). Both Switch and Scissors showed significant negative correlations with running speed and step frequency. CONCLUSIONS: The RF and BF excitation in both legs, as evidenced by changes in both Switch and Scissors, is coordinated for controlling running speed, as well as step frequency.

  • Effects of The Lower Limb Muscle Activity During Uphill Sprint Training

    Kakehata Gaku, Goto Yuta, Iso Shigeo, Kaosue Kazuyuki

    DESCENTE SPORTS SCIENCE   44   174 - 183  2023.02

     View Summary

    The purpose of this study was to clarify effect of uphill sprinting to running spatiotemporal variables and lower limb muscle activity. Twelve university sprinters (seven males) were volunteered to this study. Subjects performed 60 m sprint with maximal effort in two conditions (level sprint vs uphill sprint). Then, we obtained running spatiotemporal variables and electromyography (EMG) from lower limb muscles (biceps femoris, rectus femoris, tibial anterior, lateral head of gastrocnemius). We calculated the running spatiotemporal variables (e.g., running speed, step frequency, step length), EMG activity amplitudes (%MVC), and relative EMG timings in running cycle (%) in analysis section (40-60m). We observed running speed, step frequency, and step length were significantly decreased in the uphill sprint. However, no significant differences were observed in EMG activity amplitudes between two conditions. On the other hand, the onset and offset timings of rectus femoris muscle were significantly shifted to the latter half of the running cycle in the uphill sprint. Therefore, we may consider the possibility that delay in the timing of the recovery movement (i.e., hip flexion) of the swing leg in the uphill sprint. These results suggest that uphill sprint training may affect the timing of muscle activity rather than the amount of muscle activity. We conclude that neuromuscular control of the lower limb muscle is different between uphill sprint and level sprint.

  • The Timing of Thigh Muscle Activity Is a Factor Limiting Performance in the Deceleration Phase of the 100-m Dash

    Gaku Kakehata, Yuta Goto, Shigeo Iso, Kazuyuki Kanosue

    Medicine and science in sports and exercise   54 ( 6 ) 1002 - 1012  2022.06  [Refereed]

     View Summary

    PURPOSE: We aimed to examine the timing of electromyography activity of the rectus femoris (RF) and biceps femoris (BF) in both legs, as well as spatiotemporal variables (running speed (RS), step frequency (SF), step length (SL)) between the maximal speed (Max) phase (50-70 m) and the deceleration (Dec) phase (80-100 m) of the 100-m dash. METHODS: Nine track and field athletes performed the 100-m dash with maximal effort. Spatiotemporal variables of each 10-m section were measured. A portable wireless data logger was attached to the subject's lower back to record electromyographies. We calculated onset/offset timing (%) of RF and BF in both legs using a Teager-Kaiser Energy Operator filter (e.g., ipsilateral leg RF onset is "iRF-onset," contralateral leg BF onset is "cBF-onset") in a running cycle. RESULTS: The decreased RS in the Dec phase (P < 0.001) was due to a decreased SF (P < 0.001). Moreover, iRF-onset (P = 0.002), iRF-offset (P = 0.008), iBF-offset (P = 0.049), and cBF-offset (P = 0.017) in the Dec phase lagged in the running cycle as compared with the Max phase. Furthermore, the time difference between the swing leg RF activity (iRF-onset) and the contact leg BF activity (cBF-onset; "Scissors1") became bigger in the Dec phase (P = 0.041). Significant negative correlations were found between ΔiRF-onset and ΔSF (P = 0.045), and between ΔiBF-offset and ΔSF (P = 0.036). CONCLUSIONS: The decreased RS and SF in the Dec phase of the 100-m dash would be the delayed timing of the RF and BF activities in the same leg as well as the disturbed interleg muscular coordination.

  • Competing against another athlete side-by-side improves 60 m sprint running performance

    Gaku Kakehata, Hiroki Tsukamoto, Yuta Goto, Shigeo Iso, Kazuyuki Kanosue

    Scientific Journal of Sport and Performance   1 ( 2 ) 94 - 102  2022.05  [Refereed]

     View Summary

    Purpose: Purpose of this study was to elucidate the differences in sprint performance between two different conditions in the 60 m dash: subjects ran alone (Alone Condition: AC) or two runners competed side-by-side (Competitive Condition: CC). Methods: Subjects were twenty-six male university sprinters. They were asked to perform two 60 m dash, the AC and CC, with maximal effort from crouching start. Running spatiotemporal variables were obtained from video images taken with two digital high-speed cameras. Results: Running speed (AC: 9.34 ± 0.45 ms-1 vs CC: 9.40 ± 0.43 ms-1, p = .011) and step length (AC: 2.04 ± 0.12 m vs CC: 2.06 ± 0.10 m, p = .021) in the maximal speed section (30-60m) were significantly increased in the CC. However, there was no significant difference in step frequency (AC: 4.58 ± 0.26 Hz vs CC: 4.57 ± 0.27 Hz, p = .595). There was no significant difference in any variables in the acceleration section (0-30m). Conclusion: These results indicate that running with a competitor improves running speed with increasing step length in the maximal speed section but does not affect performance in the acceleration section. We concluded that competition improves sprint performances in the maximal speed section.

  • Spatiotemporal inflection points in human running: Effects of training level and athletic modality

    Yuta Goto, Tetsuya Ogawa, Gaku Kakehata, Naoya Sazuka, Atsushi Okubo, Yoshihiro Wakita, Shigeo Iso, Kazuyuki Kanosue

    PLoS ONE   16 ( October )  2021.10  [Refereed]

    Authorship:Lead author

     View Summary

    The effect of the different training regimes and histories on the spatiotemporal characteristics of human running was evaluated in four groups of subjects who had different histories of engagement in running-specific training; sprinters, distance runners, active athletes, and sedentary individuals. Subjects ran at a variety of velocities, ranging from slowest to fastest, over 30 trials in a random order. Group averages of maximal running velocities, ranked from fastest to slowest, were: sprinters, distance runners, active athletes, and sedentary individuals. The velocity-cadence-step length (V-C-S) relationship, made by plotting step length against cadence at each velocity tested, was analyzed with the segmented regression method, utilizing two regression lines. In all subject groups, there was a critical velocity, defined as the inflection point, in the relationship. In the velocity ranges below and above the inflection point (slower and faster velocity ranges), velocity was modulated primarily by altering step length and by altering cadence, respectively. This pattern was commonly observed in all four groups, not only in sprinters and distance runners, as has already been reported, but also in active athletes and sedentary individuals. This pattern may reflect an energy saving strategy. When the data from all groups were combined, there were significant correlations between maximal running velocity and both running velocity and step length at the inflection point. In spite of the wide variety of athletic experience of the subjects, as well as their maximum running velocities, the inflection point appeared at a similar cadence (3.0 ± 0.2 steps/s) and at a similar relative velocity (65-70%Vmax). These results imply that the influence of running-specific training on the inflection point is minimal.

    Medicine and science in sports and exercise   53 ( 3 ) 643 - 652  2021.03  [Refereed]

     View Summary

    PURPOSE: The purpose of this study was to investigate the relationship between spatiotemporal variables of running and onset/offset timing of rectus femoris (RF) and biceps femoris (BF) muscle activities in both legs. METHODS: Eighteen male well-trained athletes (age = 20.7 ± 1.8 yr) were asked to run 50 m at maximal speed. The spatiotemporal variables (running speed, step frequency, and step length) over the distance from 30 to 50 m were measured. In addition, RF and BF muscle activities were obtained from both legs using wireless EMG sensors. To quantify the onset and offset timing of muscle activity, the band-pass filtered (20-450 Hz) EMG signal was processed using a Teager-Kaiser energy operator filter. We calculated RF and BF onset/offset timings (%) in both legs (e.g., ipsilateral leg RF [iRF] and contralateral leg BF [cBF]) during running cycle. Based on those timings, we obtained the EMG timing variables (%) as follows: "Switch1 (iBF-offset to iRF-onset)," "Switch2 (iRF-offset to iBF-onset)," "Scissors1 (cBF-onset to iRF-onset)," and "Scissors2 (iRF-offset to cBF-offset). RESULTS: We found that "Switch2" had positive (r = 0.495, P = 0.037), "Scissors1" had negative (r = -0.469, P = 0.049), and "Scissors2" had positive (r = 0.574, P = 0.013) correlations with step frequency. However, these variables had no significant correlations with running speed or step length. CONCLUSIONS: These results indicate that higher step frequency would be achieved by smoother switching of the agonist-antagonist muscle activities and earlier iRF activation relative to the cBF activity. To improve sprint performance, athletes and coaches should consider not only muscle activities in one leg but also coordination of muscle activities in both legs.

    Proceedings - International Conference on Pattern Recognition     3217 - 3224  2020  [Refereed]

     View Summary

    This paper proposes a method that can classify foot strike types using a deep learning model and can extract unknown factors, which enables to evaluate running motions without being influenced by biases of sports experts, using the contribution degree of input values (CDIV). Accelerometers are attached to the runner's body, and when the runner runs, a fixed camera observes the runner and acquires a video sequence synchronously with the accelerometers. To train a deep learning model for classifying foot strikes, we annotate foot strike acceleration data for RFS (Rearfoot strike) or non-RFS objectively by watching the video. To interpret the unknown factors extracted from the learned model, we calculate two CDIVs: the contributions of the resampling time and the accelerometer value to the output (foot strike type). Experiments on classifying unknown runners' foot strikes were conducted. As a common result to sport science, it is confirmed that the CDIVs contribute highly at the time of the right foot strike, and the sensor values corresponding to the right and left tibias contribute highly to classifying the foot strikes. Experimental results show the right tibia is important for classifying foot strikes. This is because many of the training data represent difference between the two foot strikes in the right tibia. As a conclusion, our proposed method could extract unknown factors from the classifier and could interpret the factors that contain similar knowledge to the prior knowledge of experts, as well as new findings that are not included in conventional knowledge.

  • Effects of an instructional program for 5th and 6th grade children with negative feelings toward sprinting

    Suzuki Kosuke, Goto Yuta, Kakehata Gaku, Kanosue Kazuyuki

    Taiikugaku kenkyu (Japan Journal of Physical Education, Health and Sport Sciences)   64 ( 1 ) 265 - 284  2019.06  [Refereed]

     View Summary

    This study was performed to devise an instructional program for children who were not good at sprinting and to verify the program’s effectiveness for improvement of sprinting ability and motion.<br>
    The participants were 19 upper grade elementary school children who were not good at sprinting. The program included 2 drills with some teaching devices and running on flat markers. The children attended the program for 8 days (2 days per week) and each lesson lasted an hour. In order to validate the program outcome, sprint time (50 m), interval speed (every 10 m), average speed, maximal speed, rate of speed decline, interval and average step frequency and step length were analyzed, and sprint motions were evaluated. The results were as follows:<br>
    1) Most of the children’s 50 m times were below the national average. This suggested that their negative feelings toward sprinting resulted from the realization that they were unable to run as fast as other children.<br>
    2) The children’s sprint times were improved after the program, and a significant correlation between pre-time and post-pre time was revealed. It was also found that the greater the increase in the children’s step frequency, the faster their sprint times became. These results suggest that sprinting instruction allows low-performing children to increase their step frequency and improve their sprint times.<br>
    3) The main aim of the program was to improve children’s sprint motions in the mid sprint phase, and the participants practiced start motions only twice during the program. As a result, speeds from the start to 10 m, 20-50 m, and maximum speed were increased significantly by this practice, suggesting that significant changes of speed led to improvement of the sprint times.<br>
    4) Participants became able to swing back their leg under their body and to make contact with the ground with the middle or front of the foot. Therefore it was considered that the drills and running on flat markers with teaching devices were valuable for improving the children’s sprint motions.<br>
    5) Although the scissors-like leg motion was not improved by practice with a color board and bells, the kneefolding motion of the swing leg did appear to be improved. Therefore, the children seemed to acquire basic skill in more rapid scissors-like leg motion.<br>
    These results suggest that our instructional program was effective in enabling children to improve their sprinting ability and motion. However, additional research focusing on aspects such as the relationship between sprinting ability and sprint motion, or individual feelings and motor competency in the context of sprinting, will be needed.

     View Summary

    There are many situations that the difference between imagery(subjective) and actual(objective) movements occurs in skiing. In traditionally utilized feedback method with video, it is impossible to get real time visual feedback. In the present study, we developed the system for real-time visual feedback during skiing, and evaluated the availability of the system. The movie captured by a video-operator who followed a subject was projected in online through the smartglass that the subjects wore. Sixteen skiers and snowboarders with various skill levels tried this system.We interviewed subjects immediately after the trial.Their impression was that getting real-time visual feedback of their own motion utilizing the present system, which helped them modify their performance in middle and high level subjects. However, beginner subjects could not afford to use the feedback information. Since the present system had unavoidable time-delay of 186 ms, it was suggested that it is not suitable for learning short turn. Therefore, the present examination suggested that this real-time visual feedback system can be effective in learning long turn for middle and high level skier who have clear goal images of their performance.

     View Summary

    走ることは生きる上で必須の運動技能で、習わずとも2 歳~3 歳には自然と走れるようになる。しかし、そこで獲得した走り方が理にかなっているという保証はない。実際に、疾走能力にはランニングフォーム(技術)が大きく関係している。足の速い子は運動有能感を持ち、足が遅いことはスポーツ嫌いを生む要因ともなる事から、「正しいランニングフォーム」を獲得する事が重要である。本研究の目的は「正しいランニングフォーム」に重要な要素を明らかにし、それを身につけるための指導プログラムを確立する事である。
    本年度は昨年度に引き続き、1歳児から小学校高学年までの幼児・児童の走運動特性(走速度に対応したステップ長(歩幅)とケイデンス(単位時間当たりの歩数)の調整) を測定した。成人の走運動特性は低走速度ではステップ長、高走速度ではケイデンスの貢献が大きくなる特徴を有する。本年度までの測定によって、このような特性は男子女子ともに10歳児頃に生じることが示唆された。この特性の変化は第二次性徴期の開始などによる形態的な変化が要因となっている可能性がある。これまで子どもの疾走能力に関する研究は多く報告されているが、低走速度を含む走運動全体の特性にほとんど着目されてこなかった。しかし、発育発達過程で走運動特性が異なることから、本研究の結果は効果的なランニング指導の方法および指導による介入時期を検討する上で重要な知見となると考えられる。
    また、本年度は成人の走運動特性に関する論文投稿を行った。

    基礎スキーの競技会では複数の審査員が同じ滑りに対して評価を下す形式をとっており、滑走者と審査員の間で滑走に対する評価の乖離が起きている可能性がある。本研究では、スキー上級者から滑走動作時の生理学的データを収集し、従来の主観的な評価にあたる、動画データに対する指導者の評価と比較することで、計測データから滑走動作を評価することの是非を検討する。測定にあたり、スキー中上級者の4人を被験者とした。種目は、ショートポール規制小回りターンとした。滑走者はTrignoTM Wireless System (DELSYS社、アメリカ)を貼付した状態で滑走してもらった。筋活動、足圧の2種類の生理学的データと、指導員資格をもつ現役のスキー教師2名に、動画データを見てもらったうえで、評価を受け、文章化した主観的データを収集した。本研究の計測システムでは、筋活動及び足圧は効果的に計測された。前脛骨筋と踵部において、強い反応が見られた。活動の多くは単峰性の増減を示した。小回り動作では、ターンごとのばらつきが小さく、周期的に同じ動作を行っている傾向が強い。本実験で計測したデータには滑走者の技術を測る上で既存の評価と合致するものが多く見られた。

    学校体育等において誰もが経験するであろう短距離走では、「できる」自信が低いほど好感度が低くなるとされる(大塚,2013)。一方、平成29年に策定された第2期スポーツ基本計画において、子供のスポーツに対する愛好的態度を育成することの重要性が改めて示されるなど、スポーツを苦手・嫌いと感じている子供への対応は今後一層重要になると言える。そこで本研究では、子供が短距離走に対して自信を抱く上で重要となる疾走能力の向上をはかるための指導法の検討として、2016年9月~10月にかけ、埼玉県の公立小学校において計8回の放課後陸上教室を開催した。参加者は走ることが苦手と感じている5・6年生児童であり、疾走中の姿勢や上肢、下肢動作の改善をはかることを目的に、マーク走を中心としたプログラムに取り組んだ。指導の結果、6回以上参加した児童16名において、疾走動作が顕著に改善され、50m走タイムが0.30秒(p<0.01)短縮するなど、疾走能力の向上が認められた。このことから本プログラムは児童の疾走能力向上に対して有効であるが、今後は事例の蓄積とともにアンケートによって児童の運動有能感の変化を検証する必要があると考えられた。

    人の自由走行時のステップ長とケイデンスは代謝が最小になるものであると考えられている(Cavanagh et al. 1992)。それらの研究は長距離選手が対象である。長距離選手においては、効率的な動作を獲得した結果、代謝が少ない可能性があり、一般人でも同様かは不明である。そこで、走動作の変化が代謝に及ぼす影響を、ケイデンスを変化させた際の長距離選手と一般人の代謝を比較することで検討した。対象は長距離選手男性10名と、数分間継続して走行できる体力を有する一般男性10名である。測定は1日目にトレッドミルを用いて運動負荷試験を行い、60% HRreserveになる運動強度を決定した。2日目の測定ではトレッドミルの自由走行に加え、自由走行時のケイデンスから± 10%増減させたケイデンスをメトロノームで指示して走行させた。解析の結果、一般人では自由走行時に最も少ない代謝を示した。長距離選手ではケイデンス減少試行において代謝がより高くなる傾向が見られた。以上の事から一般人においても自分が身に付けている走動作では、自由なケイデンスが最も代謝が低くなると考えられる。

     View Summary

    本研究の目的は子どもの発達にともなう走速度(m/s)、単位時間当たりの歩数(ケイデンス)、一歩の長さ(ステップ長)の関係性(以下、V-C-S特性)に関する神経制御を明らかにすることである。本年度は研究の基礎データとしてまずは成人でV-C-S特性の変化と、その際の筋活動について測定を行った。V-C-S特性の性質が切り替わる点から筋活動のパターンに異なる特徴が得られた。今回の手法を用いて子どもの測定を行う予定である。本研究のデータによって2024年度若手研究に採択された。
