“…Significant differences exist between athletes using habitual UPSS-FF and UPSS-RF foot strike patterns [ 34 ]. Runners with a habitual RF strike pattern have increased strength requirements for knee flexion/stretching, and runners with a habitual FF strike mode have greater need for the degree of freedom of dorsiflexion/buckling of the ankle [ 35 , 36 ]. Along with significantly reduced peak abduction knee torque and significantly increased peak ankle moments, sprinters who habitually use the UPSS-FF strike mode rely on more ankle support.…”

Background This biomechanics study of the lower limbs aimed to compare the use of the International Society of Biomechanics Six-Degrees-of-Freedom (ISB-6DOF) model and the conventional gait model (CGM), formerly known as the Helen Hayes model, in 20 male sprinters who habitually used the forefoot (FF) or rearfoot (RF) strike modes. Material/Methods We used a motion capture system to compare the difference in lower-extremity joint mechanics between sprinters’ forefoot or rearfoot strike mode during unplanned sidestepping (UPSS). Twenty elite sprinters participated in a motion capture test under 2 models. Each of the 10 participants were classified as having a habitual forefoot strike mode or rearfoot strike mode during unplanned sidestepping. Joint mechanics and gait parameters were calculated according to the designed movement. Results Comparison of the 2 models showed that the knee joint angles were inconsistent ( P <0.05), highlighting the difficulty of the Helen Hayes model in anatomical recognition. The results of the 2 models show that during the unplanned sidestepping, the sprinter using the habitual rearfoot strike mode had a greater load through the knee joint ( P <0.05). Sprinters who used the habitual forefoot strike mode experienced greater load through their ankle joints ( P <0.05). Conclusions The findings from this biomechanics study showed that when compared with the ISB-6DoF model, the findings from the CGM were more reproducible for the evaluation of FF and RF strike during unplanned sidestepping.

“…As a result, divergent cutting kinematics and mechanics have been observed between preplanned and unplanned movement scenarios [ 37 , 69 , 151 , 155 , 156 ]. Noncontact ACL injuries were often sustained during unplanned sidestepping maneuvers [ 37 , 157 ], which might be explained by higher knee joint loads occurring during unplanned conditions [ 38 , 153 ]. Thus, tests under unplanned conditions are likely to be more representative of most sporting and injury situations where the athlete has tight time constraints when responding to a stimulus.…”

This study developed a cutting technique modification training program and investigated its effects on cutting performance and movement quality in adolescent American football players. For six weeks, an intervention group (IG) of 11 players participated in 25 min cutting technique modification training sessions integrated into team training twice a week, while a control group (CG) of 11 players continued their usual team training. Movement quality was assessed by evaluating 2D high-speed videos, obtained during preplanned 45° and 90° cutting tests, using the Cutting Movement Assessment Score (CMAS) qualitative screening tool. Cutting performance was assessed based on change of direction deficit (CODD). Significant interaction effects of time × group were found for CMAS in 45° and 90° cuttings (p < 0.001, ηp2 = 0.76, p < 0.001, ηp2 = 0.64, respectively), with large improvements in the IG (p < 0.001, g = −2.16, p < 0.001, g = −1.78, respectively) and deteriorations in the CG for 45° cuttings (p = 0.002, g = 1.15). However, no statistically significant differences in CODD were observed pre-to-post intervention. The cutting technique modification training was effective at improving movement quality without impairing cutting performance, and it can be used by practitioners working with adolescent athletes.

“…This may be related to the fact that visual stimuli, or visual feedback, affect the neuromuscular system. Several studies have demonstrated that visual stimuli enhance the activation of muscles and that different stimuli may have different effects on muscles [33][34][35]. It is important to mention that multiple types of sensory information are transmitted to the brain, which integrates them and stimulates voluntary muscle contraction.…”

The present study investigated the feasibility and effectiveness of pseudo-weight resistance training using mixed-reality (MR) technology for shoulder muscle activation in healthy individuals. Thirty-two healthy students aged 20~35 years participated in this preliminary study and were divided into two groups. Participants in the MR group received 30 min of training three times a week for 4 weeks using a customized MR-based pseudo-weight resistance training system. Those in the control group performed the same exercises using a conventional training program. Muscle activation of the deltoids, upper trapezius, infraspinatus, and supraspinatus were measured before and after the intervention. There was a statistically significant difference in middle deltoid, upper trapezius, and supraspinatus muscle activation in the MR group (p < 0.05), while the control group showed a significant difference in the anterior and middle deltoid, upper trapezius, and supraspinatus (p < 0.05). Regarding the between-group comparison, no statistically significant difference was observed for all six muscles (p > 0.05). Without any superiority of physical weight resistance training in the pseudo-weight training program, an MR-based pseudo-weight resistance training system can potentially be used for muscle-strengthening training, especially for early rehabilitation programs. However, further study using a large sample size with a long experimental duration is needed for more evidence of the presented technology and its use in home training.
