Book Synopsis The Effect of Soleus Fatigue During Sidestep Cutting Maneuvers by : Michael William Ciesa
Download or read book The Effect of Soleus Fatigue During Sidestep Cutting Maneuvers written by Michael William Ciesa and published by . This book was released on 2018 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soleus muscle is a monoarticular plantarflexor composed slow-twitch fatigue-resistant muscle fibers. Through its attachment to the proximal tibia, contraction of the soleus muscle in a closed kinetic chain (when the foot is planted) produces a posterior pulling force on the posterior proximal tibia. The anterior cruciate ligament (ACL) is responsible for preventing anterior displacement of the tibia relative to the femur. Through the production of a posterior pulling force on the tibia, soleus muscle contraction in a closed kinetic chain could help reduce strain on the ACL. Fatigue is a neuromuscular phenomenon that can alter biomechanical strategies during athletics and can increase an individual's risk of being injured. The purpose of this study is to analyze the effects soleus muscle fatigue has on knee biomechanics during the sidestep cutting maneuvers. To analyze the effects of soleus muscle fatigue, thirteen female subjects underwent a submaximal fatigue protocol targeting the soleus muscle. Biomechanical data during sidestep cutting tasks were gathered for pre-/post-soleus fatigue conditions. Additionally, dominant/nondominant limb differences were secondarily analyzed. Results showed a significant increase in peak knee extension moment in the post-soleus fatigue condition during the sidestep cutting task. We concluded that fatigue or excessive stretch of the soleus muscle puts the ACL at an increased risk for injury during sidestep cutting maneuvers. These findings provide evidence that the tricep surae muscles have an influence on knee biomechanics during dynamic exercise. Further investigation of these factors can help with the development of ACL injury prevention and rehabilitation strategies.
Book Synopsis The Relationship Between Executed Cutting Angle and Sex-leg Preference Interaction with Lower Extremity Joint Angles During Unanticipated Sidestep Cutting in Soccer Players by : Harry Brown
Download or read book The Relationship Between Executed Cutting Angle and Sex-leg Preference Interaction with Lower Extremity Joint Angles During Unanticipated Sidestep Cutting in Soccer Players written by Harry Brown and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Introduction: Effects of intended cutting angle (e.g., 30 ̊, 45 ̊, 90 ̊) on kinematics are well established. Studies have typically controlled for cut angle by omitting trials if a participant cuts more than 10 ̊ from the intended angle. However, the actual angle which the participant cuts to (i.e., executed cut angle, ECA) has rarely been measured and sufficiently controlled for. Understanding relationships between ECA and commonly measured biomechanical variables are necessary, as it may affect interpretation of previous results.Additionally, epidemiological research suggests an interaction effect whereby females are more likely to injure the anterior cruciate ligament of their non-preferred leg during non-contact circumstances. Understanding interaction effects of sex and leg preference in kinematics related to anterior cruciate ligament (ACL) injuries during cutting may offer explanation for such a phenomenon, given that cutting is a major source of such injuries in some sports. Objectives: 1a) To compare entry speed and ECA between sex and leg preference during unanticipated sidestep cutting in soccer players. 1b) To determine the relationships between ECA with peak hip and knee joint angles during unanticipated sidestep cutting in soccer players. 2) To determine if an interaction effect exists between sex and leg preference on peak hip and knee angles during unanticipated sidestep cutting in soccer players.Methods: 21 adolescent and adult male and female soccer players completed unanticipated running sidestep cuts to a prescribed 45 ̊ in both directions. Lower limb kinematics were attained via 3D motion capture. Hip and knee joint angles were calculated using a joint coordinate system, and peak angles were identified during the stance phase of cutting. Hierarchical linear modeling established relationships between peak hip/knee angles and ECA/ entry speed. Analysis of variances compared ECA between sex and leg preference. Interaction effects of sex and leg preference on peak hip/knee angles were analysed during the hierarchical linear modelling. Results: Higher ECAs were related to decreased knee flexion and valgus (i.e., more varus), and increased hip flexion and internal rotation (p range =
Book Synopsis Recovery-stress Questionnaire for Athletes by : Michael Kellmann
Download or read book Recovery-stress Questionnaire for Athletes written by Michael Kellmann and published by Human Kinetics. This book was released on 2001 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides athletic specialists, trainers, and coaches with resources for monitoring athletes to avoid over-training, burnout, and decreased performance. The questionnaire is based on the hypothesis that an accumulation of stress in different areas of life, with insufficient opportunity for recovery, leads to a compromised psychophysical state. Stress states are based on 12 nonspecific and seven sports-specific scales. The questionnaire package offers tools to measure and track an athlete's recovery, including two complete questionnaires (72- and 56-item forms), manual scoring keys, profile sheets, and a user manual that describes questionnaire development and data and profile interpretation.c.

Book Synopsis Effects of Dual Tasking on Anticipated and Unanticipated Cutting Maneuvers on Knee Biomechanics in Collegiate Male Athletes by : Taylor Frendt
Download or read book Effects of Dual Tasking on Anticipated and Unanticipated Cutting Maneuvers on Knee Biomechanics in Collegiate Male Athletes written by Taylor Frendt and published by . This book was released on 2017 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: An athlete is required to adapt to different situations throughout participation such as not knowing which direction they will be running, judging the actions of their opponents, catching or throwing a ball, and listening to the people around them. We investigated the effects of anticipation and dual tasking on trunk and lower extremity kinematics during a side step cutting maneuver in 32 healthy active males. Participants were directed with a green light to cut to the right or left either before they started running, anticipated cut, or right before they made the cut, unanticipated cut. While making the cut the participant also had to focus on possibly catching a ball meaning the ball was either faked or thrown to the participant. Our results did not indicate there was a significant effect of anticipation on a task. However, when the ball was either faked or thrown regardless of anticipation there was a decrease in lateral trunk flexion towards the stance leg at peak knee flexion and toe off. There was also an increase in trunk rotation at initial contact, peak knee flexion, and toe off when the ball was thrown. Overall, anticipation or dual tasking did not affect lower extremity kinematics.

Book Synopsis Fatigue Related Gender Differences in the Biomechanics of Drop Jumps by : Pralhad S. Bide
Download or read book Fatigue Related Gender Differences in the Biomechanics of Drop Jumps written by Pralhad S. Bide and published by . This book was released on 2008 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the present study was to determine the effects of gender and fatigue on knee kinematic and kinetic variables during the counter movement and drop jumps with specific interest on the progressive changes on knee kinematics and kinetics through out the fatigue protocol. Miami University students were recruited as study participants (n=52). Participants performed two baseline drop jumps and then were subjected to fatigue protocol for three different times. In between the fatigue protocols and at the end again they performed drop jumps. The kinetic and kinematic variables were recorded using force platform and the video cameras with SIMI motion analysis system respectively. Results indicated that with fatigue there were no changes in landing angles and in the force around the knee joint. They showed the decreased flexion at the knee joint with the progression of fatigue. Gender differences with the fatigue are also discussed.
Book Synopsis Anticipatory Effects on Lower Extremity Kinematics and Kinetics During Cutting Movements by : Ryan Ashley Mizell
Download or read book Anticipatory Effects on Lower Extremity Kinematics and Kinetics During Cutting Movements written by Ryan Ashley Mizell and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Height, accommodation to unplanned movements seems possible in the sagittal plane. Gender differences occurred at the hip as females used less hip abduction to perform the movements. Less hip abduction for females is closer to the "position of no return" seen in ACL injuries. Although our results confirmed published gender differences, this may have been due a combination of the difficulty of the tasks and the relatively low skill of the participants. Direction differences occurred as the crossover cut was performed with knee abduction and foot pronation while the opposite was true for the side cut. Furthermore, the crossover cut seemed to be performed by utilizing a preceding side cut. Therefore, the crossover cut seems to be a more dangerous movement. Although accommodation for unplanned movements may occur in the sagittal plane, unanticipated cutting movements are performed differently than anticipated cutting movements. Since anticipation can affect the performance of cutting movements, incorporation of unanticipated maneuvers should be included in training prevention programs. Also, increased development of methods for preventing anticipation is required to more closely simulate competition in the lab setting.
Book Synopsis The Effects of Fatigue on Lower Extremity Kinetics and Kinematics in Subjects with Known Ankle Instability by : Lindsay Ellen Clayton
Download or read book The Effects of Fatigue on Lower Extremity Kinetics and Kinematics in Subjects with Known Ankle Instability written by Lindsay Ellen Clayton and published by . This book was released on 2015 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this study was to evaluate biomechanical differences between healthy subjects and those with ankle instability during the gradual onset of lower extremity fatigue from a landing activity. An understanding of these differences is needed in order to prevent future injury to or further debilitation in individuals with ankle instability. A functional fatiguing activity was designed to focus fatigue on the quadriceps muscles, as those are the muscles most frequently fatigued during sport. Measures were taken throughout the progression of fatigue with a force plate and a motion tracking system and included vertical ground reaction force and lower extremity kinetics, kinematics, and energetics. The time required to reach self-reported fatigue and a balance assessment, the Star Excursion Balance Test, before and after the onset of fatigue was also recorded. Significant differences were observed between groups in peak ground reaction force, ground reaction force impulse, and frontal plane ankle joint impulse. Results indicated that subjects with ankle instability not only exhibited a different baseline for most measurements than normal subjects, but also managed the progression of fatigue differently. With this information and information from further studies, recommendations and/ or training schemes could be made and implemented to help those with ankle instability avoid recurrent injuries.
