This review focuses on methodological concepts in the evaluation of skeletal muscle function, taking into account classical muscle physiology, the developing motor system in children and anthropometric parameters. Thereby, the classical concept of kinetic and thermodynamic description of muscle function is discussed in relation to data pertaining to human physiology. Emphasis is given to the specific problems that arise when assessing muscle function during development. Two important factors influencing muscle function are discussed in detail: changes in anthropometric characteristics and changes in co-ordinative skills in the developing individual. Finally, we discuss currently available methods for the evaluation of anaerobic muscle function in children and adolescents (maximal isometric grip force, peak jump force, peak jump power, Wingate test, Bosco test).

In vertebrates, skeletal muscle comprises fast and slow fibers. Slow and fast muscle cells in fish are spatially segregated; slow muscle cells are located only in a superficial region, and comprise a small fraction of the total muscle cell mass. Slow muscles support low-speed, low-force movements, while fast muscles are responsible for high-speed, high-force movements.

Background: Frailty is a common geriatric syndrome worldwide, and its early identification and intervention have important clinical significance. Resistance training has been recommended as an efficient means to combat loss of muscle strength and mass; however, it is often not a prioritized option for older adults. Tai chi is a well-known traditional Chinese exercise that has a beneficial impact on physical performance, balance ability, metabolism, and immune function.

The First Affiliated Hospital of Sun Yat-Sen University, Guangdong, 510080, China.
Aim: The aim of this systematic review and meta-analysis was to explore the effects of different pulmonary rehabilitation on respiratory function in mechanically ventilated patients and to determine the optimal type of intervention.
Method: A comprehensive search was conducted using PubMed, Embase, Web of Science, Joanna Briggs Institute(JBI), and the Cochrane Library from their inception until September 16th, 2024. The search targeted randomized controlled trials (RCTs) comparing pulmonary rehabilitation or usual care, for improving respiratory function in mechanically ventilated patients.

Medical Spinal Research Unit, Spine Centre of Southern Denmark, University Hospital of Southern Denmark, Kolding, Denmark.
Background: Spinal pain affects up to 30% of school-age children and can interfere with various aspects of daily life, such as school attendance, physical function, and social life. Current assessment tools often rely on parental reporting which limits our understanding of how each child is affected by their pain. This study aimed to address this gap by developing MySpineData-Kids ("MiRD-Kids"), a tailored patient-reported questionnaire focusing on children with spinal pain in secondary care (Danish hospital setting).

Reliable and sensitive testing of physical function is crucial for assessing the effects of treatment or exercise intervention in various patient populations. The present study investigated the test-retest reliability and sensitivity (smallest detectable difference: SDD) of selected physical performance tests commonly used in clinical rehabilitation, including tests of habitual and maximal walking speed, walking endurance capacity, handgrip strength (HGS), and lower limb muscle power (Sit-to-Stand (STS), stair climb) in adults with severe obesity meeting the criteria for bariatric surgery. Thirty-two adults (BMI 43.
