Hunter-Sundberg ATTEMPT 211111.jpg


A 5-year (2022-2027), $3 million R01 grant funded by the NIH was awarded to Drs. Sandra Hunter and Christopher Sundberg. Their grant titled "Mechanisms of Fatigability and the Protective Effects of Exercise in People with Diabetes" aims to determine whether the greater fatigability of people with diabetes performing dynamic contractions is due to impaired vascular function leading to an increased accumulation of fatiguing metabolites. Additionally, a clinical trial will be conducted testing the effectiveness of coupling resistance exercise with blood flow restriction of the limb to improve muscle power and fatigability in people with prediabetes and type 2 diabetes.



Postdoctoral Research Associate Earns AHA Postdoctoral Fellowship 


Postdoctoral fellow, Tim Fulton, was awarded a fellowship from the American Heart Association. His fellowship will investigate whether dietary nitrate supplementation can improve fatigability in older men and women by improving vascular function and skeletal muscle bioenergetics. The duration of the fellowship is 2 years and aims to “enable applicants to develop academic careers in research alongside fulfilling clinical service commitments”. Congratulations, Tim! 


PhD student, Carlos Zepeda, received a $3,000 stipend from Marquette University’s Graduate School. Those who receive the award are chosen by a 3-member committee appointed by the Dean of the Graduate School. Applicants are rated based on their “proposed aims/methods/training goals, quality of applicant credentials, and general likelihood of being competitive for the award being sought.” Congratulations, Carlos!

R01 Grant Funded by NIA to Upgrade 3T Magnet with Multi-Nuclear Sequencing


Drs. Christopher Sundberg, Sandra Hunter, and Robert Fitts received a $250,000 R01 supplement from the NIA to upgrade a new 3T Signa Premier magnet with hardware and software to perform multi-nuclear sequencing. This upgrade will allow us to continue our whole-muscle bioenergetics studies using P-MRS.

Undergraduate Researcher Receives AHPRC Student Fellowship


Isabell Dobrzycki, an undergraduate research assistant in the Sundberg & Fitts labs, received a $1,500 research fellowship from Marquette University's Athletic and Human Performance Research Center. The Student Research Initiative is a one year fellowship, and aims to "generate interest in human performance and health-related disciplines, inspire students to address pressing contemporary societal health-related problems through research, and provide students with an immersive and meaningful experience focused in the development of research skills". Congratulations Isabell!!

Marquette University - 2020 R01 Challenge Award Winner


Drs. Sandra Hunter, Christopher Sundberg, and Robert Fitts received a $30,000 R01 Challenge Award from Marquette University for submitting a R01 grant application to the NIH and receiving a high score. The goal of this award is to catalyze the preparation and submission of competitive R01 grant applications, to increase the number of NIH applications, and to increase the number of R01 awards to Marquette faculty.

Publication Chosen as Editor's Choice Article


The Journal of Physiology selected a paper from our lab as Editor's Choice for October 2019. Bioenergetic basis for the increased fatigability with ageing by Sundberg et al. 2019 aimed to determine whether the increased fatigability in older adults is due to a greater accumulation of metabolites (inorganic phosphate, hydrogen, and diprotonated phosphate). See other Editor's Choice picks here.

Christopher Sundberg named 2018 Early Investigator Prize Winner


Christopher Sundberg was named a winner of the Early Investigator Prize by The Journal of Physiology for his publication Effects of elevated H+ and Pi on the contractile mechanics of skeletal muscle fibres from young and old men: implications for muscle fatigue in humans in the category of Exercise and Muscle. See other winners here. This publication was also highlighted by Perspectives and Journal Club articles. 


Nothing in life is fair, except that we all get 24 hours in a day.  What separates mediocrity from excellence is what we choose to do in those 24 hours.
