“…It has been shown in single-leg jump-landing, which is the same task used in the present study, that ankle plantar flexion is observed at the pVGRF when the height or distance of the jump is different, unlike the present study's results (9). However, many studies have elucidated the effects of ankle kinematics on impact absorption (11,12), indicating the importance of focusing on various parameters such as measurement timing, as well as moment (7) and displacement during landing (39).…”

“…The pVGRF changes based on the sagittal joint angle of the lower extremity during landing (7)(8)(9)(10). During singleleg landing, smaller knee and hip flexion angles (9,10) and smaller ankle dorsiflexion angles (11,12) generate larger pV-GRF magnitudes. It has been reported that the pVGRF is smaller during a landing when subjects consciously bend the knee and hip than during a natural landing (8,13).…”

Background: Impact and lower extremity joint angles during landing are factors that can increase the risk of anterior cruciate ligament injuries. However, the correlations between these factors and lower extremity muscle activation during the flight phase, which may affect these factors, are unknown. Objectives: The present study aimed to clarify the correlations between the peak vertical ground reaction force (pVGRF), sagittal joint angles during the landing phase, and the vastus medialis (VM) and semitendinosus (ST) muscle co-contraction index (CCI) during the flight phase in single-leg jump-landing. Methods: Fourteen healthy, physically active volunteers (age, 22.6 ± 2.7 years; height, 164.4 ± 7.6 cm; body weight, 58.9 ± 8.9 kg; body mass index, 21.7 ± 2.3 kg/m 2) participated. All subjects performed a single-leg jump-landing task. The pVGRF variables and the sagittal joint angles during the landing phase were measured. The CCI between the VM and ST during the flight phase was measured. The correlations between the VGRF variables, sagittal joint angles, and CCI were assessed using Spearman's rank correlation coefficient. Results: The knee flexion angle at the pVGRF was negatively correlated with the magnitude of pVGRF (ρ =-0.609, P = 0.021). The knee flexion angle at the pVGRF was negatively correlated with the CCI during the flight phase in single-leg jump-landing (ρ =-0.627, P = 0.016). Conclusions: An excessive CCI between the VM and ST during the flight phase might be indirectly related to a greater landing impact after a single-leg jump.

“…Reduced ankle dorsiflexion can alter all limb mechanics and predispose athletes to injury. 13 In addition, because NFL players' ankle ROM often approaches or exceeds normal physiologic limits, 14 an ankle ROM limitation will often hinder their performance.…”

Anterior ankle impingement is a frequent cause of pain and disability in athletes with impingement of soft-tissue or osseous structures along the anterior margin of the tibiotalar joint during dorsiflexion. In this study, we hypothesized that arthroscopic decompression of anterior ankle impingement would result in significant, reliable, and durable improvement in pain and range of motion (ROM), and would allow National Football League (NFL) players to return to their preoperative level of play. We reviewed 29 arthroscopic ankle débridements performed by a single surgeon. Each NFL player underwent arthroscopic débridement of pathologic soft tissue and of tibial and talar osteophytes in the anterior ankle. Preoperative and postoperative visual analog scale (VAS) pain scores, American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scores, and ankle ROM were compared; time to return to play (RTP), events missed secondary to surgery, and complications were recorded. All athletes returned to the same level of NFL play at a mean (SD) of 8.4 (4.1) weeks after surgery and continued playing for a mean (SD) of 3.43 (2.57) years after surgery. Mean (SD) VAS pain scores decreased significantly (P < .001), to 0.38 (0.89) from 4.21 (1.52). Mean (SD) active ankle dorsiflexion increased significantly (P < .001), to 18.86° (2.62°) from 8.28° (4.14°). Mean (SD) AOFAS hindfoot scores increased significantly (P < .001), to 97.45 (4.72) from 70.62 (10.39). Degree of arthritis (r = 0.305) and age (r = 0.106) were poorly correlated to time to RTP. In all cases, arthroscopic débridement of anterior ankle impingement resulted in RTP at the same level at a mean of 2 months after surgery. There were significant improvements in VAS pain scores, AOFAS hindfoot scores, and ROM. Arthroscopic débridement of anterior ankle impingement relieves pain, restores ROM and function, and results in reliable RTP in professional football players.

“…Many studies have shown an ankle dorsiflexion deficit as a high risk factor to develop injuries as hamstring injuries [24] or ACL injuries [25]. Mason-Mackay et al [25], in his systematic review, showed that reduced ankle dorsiflexion could alter landing biomechanics, and this predispose player to injury.…”

Background: Young soccer players' injuries are receiving increased interest. The need of adopting injury prevention strategies to reduce financial, social and sport costs is obligated. The main purpose of this study is to analyse clinical characteristics of young soccer players in order to develop specific and effective injury prevention programs. Methods: This observational, transversal study includes 25 young soccer players from Spanish National League. Strength, motor control, flexibility and range of motion characteristics were analysed before the first preseason training. Results: Statistically significant differences were found for hip internal rotation (p value = 0.001), Thomas test (p value = 0.012) and ankle dorsiflexion test (p value = 0.009) between both sides. Dorsiflexion test showed a positive correlation with the hip internal rotation ROM (p < 0.016) and with the triple hop test (p < 0.007). The hip internal rotation ROM showed a positive correlation with the Thomas test (p < 0.033) and with the single leg squat test (p < 0.008). The drop jump test showed a positive correlation with the single leg squat test (p < 0.039). Conclusions: Clinical characteristics shown in this study should be taken into account in order to develop specific injury prevention for this specific population. Moreover, data shown in this study can be used as norm values for young soccer semi-professional players in future researches.
