Flack K, Ufholz K, Johnson L, Roemmich J
Front Behav Neurosci
. 2019 Dec;
13:265.
PMID: 31849625
: This study determined whether a moderate- or high-dose exercise program increases exercise reinforcement. Increasing the relative reinforcing value of exercise (RRV; i.e., incentive sensitization of exercise) may increase the...

Games Health J
. 2019 Dec;
PMID: 31800323
Exercise reinforcement predicts physical activity of children. Repeated exposures of physical activity may increase physical activity reinforcement (incentive sensitization). Active videogame (AVG) play produces light-to-moderate-intensity physical activity. Ideally, AVG play...

Flack K, Pankey C, Ufholz K, Johnson L, Roemmich J
Behav Brain Res
. 2019 Aug;
375:112148.
PMID: 31404557
Background: Exercise is a reinforcing behavior and finding exercise highly reinforcing is characteristic of habitual exercisers. Genotypes related to dopamine metabolism moderate the reinforcing value of behaviors, but genetic moderators...

PLoS One
. 2019 May;
14(5):e0216355.
PMID: 31063478
Background: Increasing exercise reinforcement, or decreasing sedentary reinforcement, may reduce sedentary activity and promote habitual exercise. Repeated exposures to a reinforcer may increase its reinforcing value (i.e., incentive sensitization). It...

Flack K, Ufholz K, Casperson S, Jahns L, Johnson L, Roemmich J
J Acad Nutr Diet
. 2019 Apr;
119(7):1099-1108.
PMID: 30962120
Background: The Dietary Guidelines for Americans (DGA) have recommended reducing added sugar intake since its inception in 1980. Nearly 40 years later, added sugar consumption still exceeds 2015-2020 DGA recommendations...

Zacek P, Bukowski M, Mehus A, Johnson L, Zeng H, Raatz S, et al.
J Nutr Biochem
. 2018 Nov;
64:32-44.
PMID: 30428423
Saturated fatty acid (SFA) intake is associated with obesity, insulin resistance, and hepatic steatosis, but scant work examines the impact of SFA type upon these outcomes. We tested the hypothesis...

Roemmich J, Johnson L, Oberg G, Beeler J, Ufholz K
Int J Environ Res Public Health
. 2018 Aug;
15(8).
PMID: 30115825
Less physical activity among rural residents may contribute to rural-urban health disparities. Parks can be ideal community resources for promoting physical activity. This study compared park visitation and activity intensity...

Flack K, Ufholz K, Johnson L, Fitzgerald J, Roemmich J
Am J Physiol Regul Integr Comp Physiol
. 2018 Jun;
315(4):R619-R626.
PMID: 29897822
Weight loss from exercise is often less than expected. Putative compensatory mechanisms may limit exercise-induced reductions in body fat and might be proportional to exercise energy expenditure (ExEE). This study...

Selective enrichment of n-3 fatty acids in human plasma lipid motifs following intake of marine fish
Zacek P, Bukowski M, Johnson L, Raatz S, Picklo M
J Nutr Biochem
. 2017 Dec;
54:57-65.
PMID: 29257986
Plasma levels of n-3 long chain polyunsaturated fatty acids (LCPUFA) are associated with a reduction in risk of cardiovascular disease and other chronic, age-related diseases like Alzheimer's disease. In this...

Flaskerud K, Bukowski M, Golovko M, Johnson L, Brose S, Ali A, et al.
Food Sci Nutr
. 2017 Dec;
5(6):1195-1204.
PMID: 29188048
The aim of this study was to investigate the effect of various cooking techniques on the fatty acid and oxylipin content of farmed rainbow trout. Rainbow trout is an excellent...
