Effects of chronic high-fat feeding on skeletal muscle mass and function in middle-aged mice

SR Lee, AV Khamoui, E Jo, BS Park… - Aging clinical and …, 2015 - Springer
Background and aims Increased adipose tissue may promote catabolic events in skeletal
muscle. The aim of this study was to test whether high-fat diet (HFD)-induced obesity would …

The impact of a high-fat diet in mice is dependent on duration and age, and differs between muscles

GAM Messa, M Piasecki, J Hurst, C Hill… - Journal of …, 2020 - journals.biologists.com
Prolonged high-fat diets (HFDs) can cause intramyocellular lipid (IMCL) accumulation that
may negatively affect muscle function. We investigated the duration of a HFD required to …

Altered lipid metabolism impairs skeletal muscle force in young rats submitted to a short-term high-fat diet

DE Andrich, Y Ou, L Melbouci… - Frontiers in …, 2018 - frontiersin.org
Obesity and ensuing disorders are increasingly prevalent in young populations. Prolonged
exposure to high-fat diets (HFD) and excessive lipid accumulation were recently suggested …

Moderators of skeletal muscle maintenance are compromised in sarcopenic obese mice

LA Brown, RA Perry Jr, WS Haynie, DE Lee… - Mechanisms of ageing …, 2021 - Elsevier
The purpose of this study was to determine whether sarcopenic obesity accelerates
impairments in muscle maintenance through the investigation of cell cycle progression and …

Long‐Chain Fatty Acids and Inflammatory Markers Coaccumulate in the Skeletal Muscle of Sarcopenic Old Rats

T Laurentius, R Kob, C Fellner, M Nourbakhsh… - Disease …, 2019 - Wiley Online Library
Obesity and inflammation are reportedly associated with the pathogenesis of sarcopenia,
which is characterized by age‐related loss of skeletal muscle mass. Intramuscular fat …

Early oxidative shifts in mouse skeletal muscle morphology with high‐fat diet consumption do not lead to functional improvements

MM Thomas, KE Trajcevski, SK Coleman… - Physiological …, 2014 - Wiley Online Library
Short‐term consumption of a high‐fat diet (HFD) can result in an oxidative shift in adult
skeletal muscle. However, the impact of HFD on young, growing muscle is largely unknown …

A chronic high-fat diet exacerbates contractile dysfunction with impaired intracellular Ca2+ release capacity in the skeletal muscle of aged mice

H Eshima, Y Tamura, S Kakehi… - Journal of Applied …, 2020 - journals.physiology.org
Obesity and aging reduce skeletal muscle contractile function. However, it remains unclear
whether obesity additively promotes muscle contractile dysfunction in the setting of aging. In …

Chronic high fat feeding attenuates load‐induced hypertrophy in mice

M Sitnick, SC Bodine, JC Rutledge - The Journal of physiology, 2009 - Wiley Online Library
The incidence of obesity and obesity‐related conditions, such as metabolic syndrome and
insulin resistance, is on the increase. The effect of obesity on skeletal muscle function …

Lipogenic regulators are elevated with age and chronic overload in rat skeletal muscle

DA Rivas, EP Morris, RA Fielding - Acta Physiologica, 2011 - Wiley Online Library
Aim: Both muscle mass and strength decline with ageing, but the loss of strength far
surpasses what is projected based on the decline in mass. Interestingly, the accumulation of …

Does dietary-induced obesity in old age impair the contractile performance of isolated mouse soleus, extensor digitorum longus and diaphragm skeletal muscles?

C Hill, RS James, VM Cox, J Tallis - Nutrients, 2019 - mdpi.com
Ageing and obesity independently have been shown to significantly impair isolated muscle
contractile properties, though their synergistic effects are poorly understood. We uniquely …
