Molecular and neural adaptations to neuromuscular electrical stimulation; Implications for ageing muscle (2020)
Journal Article
Guo, Y., Phillips, B. E., Atherton, P. J., & Piasecki, M. (2021). Molecular and neural adaptations to neuromuscular electrical stimulation; Implications for ageing muscle. Mechanisms of Ageing and Development, 193, Article 111402. https://doi.org/10.1016/j.mad.2020.111402

One of the most notable effects of ageing is an accelerated decline of skeletal muscle mass and function, resulting in various undesirable outcomes such as falls, frailty, and all-cause mortality. The loss of muscle mass directly leads to functional... Read More about Molecular and neural adaptations to neuromuscular electrical stimulation; Implications for ageing muscle.

Influence of sex on the age?related adaptations of neuromuscular function and motor unit properties in elite masters athletes (2020)
Journal Article
Piasecki, J., Inns, T. B., Bass, J. J., Scott, R., Stashuk, D. W., Phillips, B. E., …Piasecki, M. (2021). Influence of sex on the age‐related adaptations of neuromuscular function and motor unit properties in elite masters athletes. Journal of Physiology, 599(1), 193-205. https://doi.org/10.1113/jp280679

Motor unit (MU) remodelling acts to minimise loss of muscle fibres following denervation in older age, which may be more successful in masters athletes. Evidence suggests performance and neuromuscular function decline with age in this population, alt...

Near Fibre Electromyography (2020)
Working Paper
Piasecki, M., C Estruch, O. G., & Stashuk, D. W. Near Fibre Electromyography

Near fibre electromyography (NFEMG) is the use of specifically high-pass filtered motor unit potential (MUPs) (i.e. near fibre MUPs (NFMs)) extracted from needle-detected EMG signals for the examination of changes in motor unit (MU) morphology and el... Read More about Near Fibre Electromyography.

Absence of an ageing?related increase in fibre type grouping in athletes and non?athletes (2020)
Journal Article
Messa, G. A., Piasecki, M., Rittweger, J., McPhee, J. S., Koltai, E., Radak, Z., …Degens, H. (2020). Absence of an ageing‐related increase in fibre type grouping in athletes and non‐athletes. Scandinavian Journal of Medicine and Science in Sports, 30(11), 2057-2069. https://doi.org/10.1111/sms.13778

The ageing‐related loss of muscle mass is thought to be partly attributable to motor neuron loss and motor unit remodelling that result in fibre type grouping. We examined fibre type grouping in 19‐ to 85‐year‐old athletes and non‐athletes and evalua...

Targeted genotype analyses of GWAS-derived lean body mass and handgrip strength-associated single nucleotide polymorphisms in elite masters athletes (2020)
Journal Article
Crossland, H., Piasecki, J., McCormick, D., Phillips, B. E., Wilkinson, D. J., Smith, K., …Atherton, P. J. (2020). Targeted genotype analyses of GWAS-derived lean body mass and handgrip strength-associated single nucleotide polymorphisms in elite masters athletes. AJP - Regulatory, Integrative and Comparative Physiology, 319(2), R184-R194. https://doi.org/10.1152/ajpregu.00110.2020

Recent large genome-wide association studies (GWAS) have independently identified a set of genetic loci associated with lean body mass (LBM) and handgrip strength (HGS). Evaluation of these candidate single nucleotide polymorphisms (SNPs) may be usef...

Relationship of anabolic hormones with motor unit characteristics in quadriceps muscle in healthy and frail ageing men (2020)
Journal Article
Swiecicka, A., Piasecki, M., Stashuk, D., Jones, D., Wu, F., McPhee, J., & Rutter, M. K. (2020). Relationship of anabolic hormones with motor unit characteristics in quadriceps muscle in healthy and frail ageing men. Journal of Clinical Endocrinology and Metabolism, 105(7), https://doi.org/10.1210/clinem/dgaa100

Context Anabolic hormones are important factors in maintaining muscle mass for ageing men, but their role in overall motor unit structure and function is unclear. Objective To determine associations of anabolic and reproductive hormone levels wi...

The impact of a high-fat diet in mice is dependent on duration and age, and differs between muscles (2020)
Journal Article
Messa, G. A. M., Piasecki, M., Hurst, J., Hill, C., Tallis, J., & Degens, H. (2020). The impact of a high-fat diet in mice is dependent on duration and age, and differs between muscles. Journal of Experimental Biology, 223(6), https://doi.org/10.1242/jeb.217117

© 2020. Published by The Company of Biologists Ltd. 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 instigate these cha... Read More about The impact of a high-fat diet in mice is dependent on duration and age, and differs between muscles.
