Breakfast Protein Quality and Muscle Strength in Japanese Older Adults: A Community-Based Longitudinal Study
The amount of breakfast protein intake is important for maintaining muscle strength. However, the effect of breakfast protein quality (ie, bioavailability) remains unclear. We investigated the association between breakfast protein quality and the incidence of muscle weakness.

Malnutrition in Relation to Muscle Mass, Muscle Quality, and Muscle Strength in Hospitalized Older Adults
Muscle quality is an essential muscle metric, which can be assessed by measuring intermuscular adipose tissue (IMAT) and skeletal muscle radiodensity (SMD) via computed tomography (CT) images. We aimed to explore the associations of Global Leadership Initiative on Malnutrition (GLIM)–defined malnutrition w...

Cut Points of Chair Stand Test for Poor Physical Function and Its Association With Adverse Health Outcomes in Community-Dwelling Older Adults: A Cross-Sectional and Longitudinal Study
To identify the optimal cutoff points for poor physical function [measured by a 5-times sit-to-stand (5-STS) test] associated with slowness in community-dwelling older adults and to validate the 5-STS cut points by determining whether they predicted future slowness and clinically relevant health outcomes o...

Is High-Speed Resistance Training an Efficient and Feasible Exercise Strategy for Frail Nursing Home Residents?
High-speed resistance training (HSRT) has been strongly recommended by experts in the field as a possible strategy to manage frailty in older adults; however, investigations to support this hypothesis are still lacking. Frailty is highly prevalent in nursing home residents and understanding if HSRT might c...

Estimation of Muscle Mass Using Creatinine/Cystatin C Ratio in Japanese Community-Dwelling Older People
Sarcopenia is defined as a combination of low skeletal muscle mass index (SMI), weak muscle strength, and reduced physical function. Recently, many studies have reported that the creatinine/cystatin C ratio (Cr/CysC) is useful for evaluating muscle mass. We designed a cross-sectional study with separate mo...

Delayed Dysphagia May Be Sarcopenic Dysphagia in Patients After Stroke
In many cases, swallowing function is impaired after the onset of stroke and gradually improves. However, delayed dysphagia has been reported in some post-stroke patients. Recently, several studies have reported that low muscle strength and decreased muscle mass cause dysphagia. This study aimed to investi...

Assessing Additional Characteristics of Muscle Function With Digital Handgrip Dynamometry and Accelerometry: Framework for a Novel Handgrip Strength Protocol
Maximal handgrip strength (HGS) is a convenient and reliable, but incomplete, assessment of muscle function. Although low HGS is a powerful predictor of poor health, several limitations to maximal HGS exist. The predictive value of HGS is restricted because low HGS is associated with a wide range of unspec...

Reliability and Concurrent Validity of the SARC-F and Its Modified Versions: A Systematic Review and Meta-Analysis
Sarcopenia, being prevalent in up to 40% of older adults, is associated with adverse health outcomes. The international sarcopenia guidelines recommend screening for sarcopenia using the SARC-F. A previous meta-analysis (2017) reported poor validity of the SARC-F among community-dwelling older adults. Sinc...
