Available in PDF, EPUB and Kindle. Book excerpt: His study investigated the lower limb biomechanics during downhill and uphill running in habitual forefoot strike and habitual rearfoot strike runners. Fifteen habitual forefoot strike and fifteen habitual rearfoot strike recreational male runners ran at 3 m/s ± 5% during level, uphill and downhill overground running on a ramp mounted at 6° and 9°. Results showed that hill running had similar impacts on joint angles in rearfoot strike and forefoot strike runners, causing a decrease in hip flexion at initial contact during downhill running, an increase in knee flexion angle at initial contact during uphill running and a decrease in peak hip flexion angle. In addition to differences in ankle joint angle due to landing pattern difference between rearfoot strike and forefoot strike runners, forefoot strike runners had a more flexed hip angle during downhill running. Forefoot strike runners had an absent impact peak in all running conditions, while the impact peaks only decreased during the uphill conditions in rearfoot strike runners. Active peaks decreased during the downhill conditions in forefoot strike runners while active loading rates increased during downhill conditions in rearfoot strike runners. Compared to the level condition, parallel braking peaks were larger during downhill conditions and parallel propulsive peaks were larger during uphill conditions. Peak hip flexion moment was significantly greater while peak knee flexion moment was significantly lower in both groups during the downhill 9° condition. Forefoot strike runners had larger peak plantar flexion moments and peak ankle power absorption compared to rearfoot strike runners during all conditions. Forefoot strike runners had decreased peak power absorption at the knee joint during downhill and level running conditions. Combined with previous biomechanics studies, our findings of no impact peak in forefoot strike runners suggests that this landing pattern may have potential in reducing overuse running injuries. Forefoot strike running reduces loading at the knee joint and can be used as an effective strategy to reduce stress at the knee joint experienced with rearfoot strike running.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: OBJECTIVES: Comparing electromyography and physiological measures while walking on various inclines in unstable and stable shoes.METHODS: Eleven healthy females walked on treadmill at +10%, 0% and -10% grade for five minutes each, at self-selected pace, in stable and unstable shoes. The two sessions were done 3weeks apart during which the subjects used unstable shoes for regular activities. Electromyography of lower limb muscles, absolute and relative oxygen consumption, perceived exertion rating and heart rate was calculated.RESULTS: Tibialis anterior activation varied significantly with shoe type, irrespective of grade. Soleus, vastus medialis, and biceps femoris showed activation differences in specific gait phases. There was a main effect for absolute and relative oxygen consumption, RPE and HR only with grade. Shoe type showed no effect. CONCLUSION: Though there is no difference in overall physiological variables, but changes in electromyography in specific phases highlight possible muscle toning benefits of unstable shoes.

Download or read book Kinematics and Joint Coupling in Runners with Patellofemoral Pain During a Prolonged Run written by and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Running in a fatigued state has been proposed as one of the primary factors relating to overuse injuries associated with running. Patellofemoral pain (PFP) syndrome has long been the most common overuse injury that runners sustain, yet the etiology of PFP is not clearly understood. The overall goal of this work was to examine lower extremity kinematics and joint coupling over the course of a prolonged run in runners with and without PFP. In aim one of this work, lower extremity kinematics and joint coupling were analyzed in 20 uninjured runners over a prolonged run. Running with exertion was associated with small increases in kinematics, and altered continuous relative phase (CRP) coupling patterns during the first half of stance. In the second aim, the lower extremity kinematics of 20 runners with PFP were compared to 20 uninjured runners over a prolonged run. The PFP group displayed less overall motion, suggesting a strategy of stiffening the leg in response to pain. Three distinct PFP subgroups emerged, with each subgroup demonstrating unique kinematic patterns, suggesting that a number of different kinematic mechanisms for PFP may exist. In aim three, lower extremity joint coupling of 20 runners with PFP were compared to 20 uninjured runners over a prolonged run. The PFP group demonstrated prolonged eversion and an earlier peak knee internal rotation, which disrupted the normal coupling throughout the leg. At the end of the run, CRP coupling in the PFP group resembled the uninjured group at the beginning, suggesting a compensatory strategy in response to pain. In aim four, hip strength, and its relationship to hip angles when running, was compared between 20 runners with PFP and 20 uninjured runners. The PFP group displayed weaker hip muscles, which related to increased hip adduction when running, suggesting a minimum level of hip strength is needed to maintain femoral alignment when running. In summary, runners with PFP exhibit abnormal kinematics and joint coupling over a prolonged run, which may be related to weaker hip muscles. This work demonstrates that PFP is likely a multifactorial syndrome, and prevention and treatment strategies should be tailored accordingly.

This book was released on 2017 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract:INTRODUCTION: Patellofemoral pain (PFP) is a common overuse injury where the cause of the pain is largely unknown. Previous research has not compared the variability of joint coordination and kinematics in the same study. PURPOSE: The purpose of this study was to examine the effects of PFP and exertion on the variability of lower extremity kinematics, and joint coordination. METHODS: The participants included 6 female runners with PFP (R-PFP) (21.0 ± 0.55 years; 66.1 ± 7.9 kg; 1.62 ± 0.09 m), and a control group of 6 healthy female runners (CON) (21.2 ± 1.17 years; 61.5 ± 6.9 kg; 1.67 ± 0.11 m). Sixteen anatomical retroreflective markers, as well as 4 tracking clusters, were placed on the participants’ lower extremities. The participants ran at a self-selected pace on an instrumented treadmill. Data collected from the beginning, middle, and end of the run was analyzed. Joint kinematic and joint coordination (CRP) variability were calculated. RESULTS: R-PFP finished the run with significantly larger knee adduction peak angle variability, F(2, 10) = 4.14, p
