  • Knee confidence in youth and young adults at risk of post-traumatic osteoarthritis 3-10 years following intra-articular knee injury 

    Ezzat, A M; Whittaker, J L; Toomey, C; Doyle-Baker, P K; Brussoni, M; Emery, C A (Cumming School of Medicine, Environmental Design, Kinesiology, University of Calgary, Post-print, 2018-07)
    To examine differences in knee confidence between individuals with a history of youth sport-related knee injury and uninjured controls.
  • Analysis of serum cortisol to predict recovery in paediatric sport-related concussion 

    Ritchie, E V; Emery, C; Debert, C T (Kinesiology, Cumming School of Medicine, Clinical Neurosciences, University of Calgary, Post-print, 2018-02-05)
    To study the relationship between acute serum cortisol following pediatric sport-related concussion (SRC) and clinical outcome measures of symptom burden and length to return to sport (RTS) Methods: Prospective observational ...
  • Contribution of individual quadriceps muscles to knee joint mechanics 

    Han, Seongwon; Sawatsky, Andrew; Fontana, Heiliane de Brito; Herzog, Walter (Kinesiology, University of Calgary, Publisher's version, 2019-03)
    Many attempts have been made to determine the contribution of individual muscles in an agonistic group to the mechanics of joints. However, previous approaches had the limitations that muscles often could not be controlled ...
  • Absence of differences between male and female adolescents with prior sport concussion 

    Brooks, Brian L; Mrazik, Martin; Barlow, Karen M; McKay, Carly D; Meeuwisse, Willem H; Emery, Carolyn A (Wolters Kluwer, Cumming School of Medicine, Kinesiology, University of Calgary, University of Alberta, http://www.wkopenhealth.com/Institutions.html, Post-print, 2014-01)
    Sex differences following concussion are poorly understood. The purpose of this study was to examine whether male and female adolescent athletes with prior concussions differ regarding neurocognitive function and symptom ...
  • Subjective, but not objective, lingering effects of multiple past concussions in adolescents 

    Brooks, Brian L; McKay, Carly D; Mrazik, Martin; Barlow, Karen M; Meeuwisse, Willem H; Emery, Carolyn A (Mary Ann Liebert, Inc., Kinesiology, University of Calgary, https://home.liebertpub.com/page/self-archiving/51, 2013-09-01)
    The existing literature on lingering effects from concussions in children and adolescents is limited and mixed, and there are no clear answers for patients, clinicians, researchers, or policy makers. The purpose of this ...
  • Protective effect of prebiotic and exercise intervention on knee health in a rat model of diet-induced obesity 

    Rios, Jaqueline Lourdes; Bomhof, Marc R.; Reimer, Raylene A.; Hart, David A.; Collins, Kelsey H.; Herzog, Walter (Kinesiology, University of Calgary, 2019-03-07)
    Obesity, and associated metabolic syndrome, have been identified as primary risk factors for the development of knee osteoarthritis (OA), representing nearly 60% of the OA patient population. In this study, we sought to ...
  • Stiffness of Hip Adductor Myofibrils is decreased in Children with Spastic Cerebral Palsy 

    Leonard, Timothy R.; Howard, Jason J.; Larkin-Kaiser, Kelly A.; Joumaa, Venus; Logan, Karl J.; Orlik, Benjamin; El-Hawary, Ron; Gauthier, Luke E.; Herzog, Walter (Elsevier, Kinesiology, Human Performance Lab, University of Calgary, IWK Health Centre, Halifax, Weill Cornell Medicine, Sidra Medicine, Qatar, Post-print, 2019-02-23)
    Cerebral palsy (CP) is the result of a static brain lesion which causes spasticity and muscle contracture. The source of the increased passive stiffness in patients is not understood and while whole muscle down to single ...
  • A Stochastic Simulation of Skeletal Muscle Calcium Transients in a Structurally Realistic Sarcomere Model using MCell 

    Holash, Robert John; MacIntosh, Brian R. (PLOS Computational Biology, Kinesiology, Human Performance Lab, University of Calgary, 2019-01-30)
    Skeletal muscle contraction is initiated when an action potential triggers the release of Ca2+ into the sarcomere in a process referred to as excitation-contraction coupling. The speed and scale of this process makes direct ...
  • Quadrupedal Locomotion-Respiration Entrainment and Metabolic Economy in Cross-Country Skiers 

    Boldt, Kevin Rudi; Killick, Anthony; Herzog, Walter (Kinesiology, 2016-02)
    A 1:1 locomotion-respiration entrainment is observed in galloping quadrupeds, and is thought to improve running economy. However, this has not been tested directly in animals, as animals cannot voluntarily disrupt this ...
  • Energetic Considerations in Cross-Country Skiing 

    Herzog, Walter; Killick, Anthony; Boldt, Kevin Rudi (Springer, Kinesiology, Human Performance Lab, University of Calgary, 2015-01)
    Cross-country skiing is a four-legged gait, and some gait patterns, such as 2-skate skiing, are similar to those adopted by animals (galloping horse). Four-legged animals change gait patterns with increasing speeds of ...
