“…In adults, several studies have demonstrated greater antagonist coactivation in women compared with men during single-joint concentric and eccentric contractions, as well as during jumping tasks (De Ste Croix et al, 2017;Krishnan et al, 2015;Marquez et al, 2017;Smith et al, 2021). Sex-differences in antagonist coactivation during the pubescent years are of particular interest, due the high prevalence of anterior cruciate ligament injuries among adolescent females (Hewett et al, 2006(Hewett et al, , 2004Montalvo et al, 2019;Tursz and Crost, 1986).…”

“…무릎 관절의 동적 안정성은 조화로운 움직임의 발달과 실행에 필 수적이기 때문에 (Smith et al, 2021), 무릎을 둘러싼 굴곡근과 신 전근은 동시에 수축하거나 활성화되어 관절의 안정성을 유지하며 (Bencke & Zebis, 2011), 사이드 커팅과 같은 동작 동안 뒤넙다리근 (Hamstring)은 넙다리네갈래근과 공동활성화하면서 정강이뼈의 앞 쪽 당김에 대한 길항근 역할을 가지고 넙다리네갈래근의 수축으로 인 해 앞십자인대에 가해지는 스트레스를 잠재적으로 낮추는데 기여한 다 (Baratta et al, 1988). 하지만, 약화 된 길항근이 비대 된 주동근 에 대해 감소 된 공동활성화 패턴을 나타내는 경우 앞십자인대 손상 과 미래의 비접촉 앞십자인대 파열 및 손상 위험이 증가할 수 있다 (Baratta et al, 1988;Oliveira et al, 2013).…”

PURPOSE This study aimed to identify the lower limb muscle activity based on direction prediction presence or absence and gender during side cutting in healthy college students. METHODS The study participants included 14 healthy males and females (8 males; 6 females). All participants ran at full speed for a distance of 12m, and side-cutting was carried out at 45 degrees in a randomly indicated direction and in a fixed direction. Simultaneously, data regarding vastus medialis, vastus lateralis, semitendinosus, and biceps femoris muscle activity of the dominant leg were collected using an electromyography sensor, and data regarding vertical acceleration were collected using an inertial sensor attached to the pelvis. A sync webcam was used for obtaining the initial contact of side cutting and the stance period time. During the 10 milliseconds (pre-activation) prior to the initial contact and 50% of the stance phase (loading phase), vastus medialis, vastus lateralis, semitendinosus, and biceps femoris average muscle activity and hamstring to quadriceps ratio included as variables. RESULTS During the pre-activation and loading phase, the vastus medialis muscle activity of the male group was higher in the unexpected condition than in the expected condition. Furthermore, hamstring to quadriceps ratio was confirmed to be lower under unexpected condition compared to under expected condition during on loading phase. CONCLUSIONS The study results suggest that the risk of anterior cruciate ligament injury may increase with side cutting under unpredictable conditions. It is expected to provide useful information for identifying factors related to knee injury in the general population.

“…Altered motor control and coordinated muscular contraction are fundamental to normal body function. Functional activities such as trunk extension require trunk stability ( Smith et al, 2021 ), so the muscle groups that make up the functional unit of trunk extension must contract or co-activate simultaneously, thereby triggering a whole-body muscular response ( Kocyigit et al, 2023 ). However, fewer articles have been published examining the mechanical behavior of trunk and lower limb muscles and the mechanisms of coordinated muscle contraction.…”

Purpose: To investigate the effect of isometric prone trunk extension (IPTE) contraction intensity on the stiffness of erector spinae (ES), semitendinosus (ST), biceps femoris (BF), and gastrocnemius muscles to understand the overall muscle mechanical behavior during IPTE and to explore the mechanisms of oordinated contraction of the body kinetic chain.Methods: Twenty healthy females were recruited, and participants underwent IPTE at three contraction intensities, i.e., 0% maximum voluntary isometric contraction (MVIC), 30% MVIC, and 60% MVIC, and muscle stiffness was measured using MyotonPRO.Results: Muscle stiffness was moderately to strongly positively correlated with contraction intensity (r = 0.408–0.655, p < 0.001). The percentage increase in stiffness at low intensity was much greater in ES than in lower limb muscles and greater in ST and BF than in gastrocnemius, whereas at moderate intensity, the percentage increase in stiffness decreased in all muscles, and the percentage increase in stiffness in ES was lower than that in ST. There was a moderate to strong positive correlation between ES stiffness variation and ST (r = 0.758–0.902, p < 0.001), BF (r = 0.454–0.515, p < 0.05), MG (r = 0.643–0.652, p < 0.01), LG (r = 0.659–0.897, p < 0.01).Conclusion: IPTE significantly affected the stiffness of lumbar and lower limb muscles, and low-intensity IPTE activated the ES more efficiently. There were significant coordinated muscle contractions between ES, ST, and LG. This provides preliminary evidence for exploring the overall modulation pattern of the lumbar and lower limb muscles’ kinetic chains. In future studies, we will combine other stiffness assessment methods (such as Magnetic Resonance Elastography, Shear Wave Elastography, or electromyography) to corroborate our findings.
