Latest from our group exploring potential mechanisms involved in appetite regulation post-exercise. We show glucose/insulin are not involved as they changed similarly with MICT and SIT but with differential appetite responses. @_mccarthyseth @DBornath https://t.co/KwsGAFZqHe

Excited to share that I will be starting as an Assistant Professor at @Laurier in Kinesiology (@LaurierKin) in July 2025! The lab will focus on cardiovascular physiology, with an emphasis on women+. Recruiting MSc students to start Sept 2025, so spread the word!

@jens_lund Yes. The dosage we used was based on previous work and we understand the potential implications of hypertonic solutions. As we were focused on lactate's mechanisms (and not measuring EI), we used a dose that had previously been shown to alter neuropeptide expression.

Excited to share another PhD study. In collaboration with Dr. Rebecca MacPherson (not on X) we demonstrated that lactate accumulation due to exercise or peripheral injection does not alter central or peripheral appetite signaling 2 h post exer/inj.

The companion paper from Dr. MacPherson’s group demonstrated lactate accumulation due to exercise and peripheral injection alters brain BACE1 and ADAM10 activity and shifts amyloid precursor protein processing away from beta-amyloid production.

Excited to get some work from my PhD published. We planned to use oral lactate ingestion to assess lactate's role in appetite regulation, however during piloting we found it ineffective at increasing blood lactate using a variety of dosages based on previous studies.

Latest from our group regarding the potential mechanisms involved in exercise-induced appetite suppression that were proposed nearly a decade ago. Here we provide an update on those mechanisms and highlight new advances in the field that should be the focus of future work.

Interesting results & latest from our group. Reducing exercise volume from 2 min (8x15 sec sprints) to 1 min (4x15 sec sprints) had similar effects on post-exercise metabolism. Viable “on-ramp” for those looking to build up to higher volume protocols?

Limited work has explored the effect of RT exercise on appetite and here we show that lifting light or heavy but to fatigue generates exercise-induced appetite suppression coinciding with changes in acylated ghrelin https://t.co/AzBLbCdrQU

New meta-analysis from my lab! We have been interested in the role of the menstrual cycle on appetite-regulation for several years.  Here we show the available data suggests a small yet important increase in energy intake in the LP compared to the FP.  https://t.co/whGYTdJgKT

@NanciGuestRDPhD @brady_h I went to high school with him, from what I understand it was received well.

Outdoor gyms seem to be an accessible option to reduce several barriers to exercise, but do they provide benefit?

Check out this new publication to see how outdoor gyms can be used to improve relative strength and physical function in older adults!
