Special Issue Information

Dear Colleagues,

Muscle strength, also known as muscular strength, is vital to physical health, especially for aging populations. This Special Issue explores recent advancements and practical applications in muscle strength assessment, development, and maintenance across various age groups, particularly focusing on older adults. Relevant keywords include "muscle strength," "sarcopenia," "resistance training," "aging," and "functional mobility". This issue will also cover innovative interventions, exercise programs, and nutritional strategies to prevent or mitigate muscle deterioration. Additionally, it addresses the role of muscle strength in daily functions, community participation, and overall quality of life. This Special Issue seeks to support a comprehensive understanding of muscle strength's physiological and societal impacts, serving as a valuable resource for health professionals, researchers, and policy-makers dedicated to improving health outcomes in vulnerable populations. The goal is to offer insights that promote effective strategies for enhancing muscle strength and functionality, ultimately fostering healthier, more active aging.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Handgrip strength (HGS) is a key indicator of muscular fitness and physical health. Recently, attention has focused on HGS asymmetry as a potential marker of functional impairment. The aim of the study was to analyze differences in handgrip strength between the dominant and non-dominant limbs and to assess the influence of age and sex on asymmetry levels within the Polish population. A total of 341 participants (170 women and 171 men) were divided into two groups: younger (18–35 years) and older (50+). HGS was measured using a Noraxon digital dynamometer, and asymmetry was defined as the ratio of dominant to non-dominant handgrip strength. Most of the participants (approximately 70%) exhibited greater strength in their dominant hand, with a mean asymmetry values ranging from 17% to 19%. Older adults showed lower overall HGS than younger adults, however, the asymmetry did not differ significantly between sexes or age groups. A small asymmetry (≤10%) was the most common among participants. The Polish adult population shows moderate asymmetry in handgrip strength, with a predominance of the dominant hand, regardless of age or gender. Measuring grip strength asymmetry may provide useful information for assessing the function of the upper limbs and could be important for monitoring physical fitness, identifying neuromuscular disorders, and preventing the decline of motor function in older adults.
