Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The European Working Group on Sarcopenia in Older People (EWGSOP) established diagnostic criteria for sarcopenia based on muscle mass, strength, and physical performance in 2010, later revised in 2018 (EWGSOP2), emphasizing low muscle strength as the primary diagnostic criterion. The SARC-F questionnaire is recommended for confirming sarcopenia, with a score of ≥ 4 indicating the condition.
The concept of respiratory sarcopenia, introduced in 2021, refers to the loss of respiratory muscle mass and strength alongside general body sarcopenia, though measuring respiratory muscle mass can be complex. Respiratory muscle strength can be assessed through mouth pressure measurement, but a consensus on the methodology is still lacking.
Overall, there is insufficient research on the relationship between peripheral and respiratory muscle weakness and sarcopenia in the elderly. This study aims to explore this relationship further.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Sarcopenia is a progressive and characterized loss of skeletal muscle mass (SMM) and function associated with aging. Several prospective studies have reported that skeletal muscle mass decreases by 6% per decade after middle age. In community healthcare settings, the prevalence of sarcopenia has been reported to reach up to 29% among older adults. Sarcopenia is thought to involve a variety of pathophysiological processes, including denervation, mitochondrial dysfunction, inflammatory and hormonal changes that can lead to adverse health outcomes such as falls, functional decline, frailty, weakness, and death due to a decrease in lean body mass. The European Working Group on Sarcopenia in Older People (EWGSOP) proposed three diagnostic criteria for sarcopenia based on muscle mass, muscle strength, and physical performance in 2010. The EWGSOP proposed for sarcopenia three diagnostic criteria; low muscle mass (LMM) is defined by a SMM index of less than 8.90 kg/m2, low muscle strength (LMS) by hand-grip strength below 30 kg in men and 20 kg in women, and low physical performance (LPP) by gait speeds of less than 0.8 m/s. In 2018, The European Working Group on Sarcopenia in Older People 2 (EWGSOP2) revised the diagnostic criteria and established that low muscle strength is the primary parameter for the diagnosis of sarcopenia and the most reliable measure of muscle function. In clinical practice, when a patient shows symptoms or signs of sarcopenia (i.e. falls, feeling weak, walking slowly and difficulty getting up from a chair, or weight loss or muscle wasting), the EWGSOP2 is recommended to use the SARC-F questionnaire, which consists of five items: Strength, Assistance in walking, Rising from a chair, Climbing stairs, and Falls to confirm the diagnosis. A score of the SARC-F questionnaire ≥ 4 is considered sarcopenia.
The concept of respiratory sarcopenia was first proposed in 2021 and is defined as "General body sarcopenia and low respiratory muscle mass followed by low respiratory muscle strength and/or low respiratory function." Diagnosis of respiratory sarcopenia is made by assessing respiratory muscle mass and strength. However, measuring respiratory muscle mass can often be complex, requiring advanced diagnostic equipment or techniques such as ultrasound echography and computed tomography. Assessing respiratory muscle strength is easier because it can be measured by mouth pressure measurement; however, there is no consensus yet on the exact methodology.
Studies showing the relationship between peripheral muscle and respiratory muscle weakness and sarcopenia in the elderly population are insufficient. In our study, we aim to examine the relationship between sarcopenia and peripheral and respiratory muscle strength.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Elderly Individuals
The study group was composed of volunteers aged 65-80 years.
Questionnare, hand grip and respiratory muscle strength
Upper extremity strength will be assessed using the Jamar hand dynamometer to measure hand grip strength. For lower extremity muscle strength, participants will undergo the five-repetition sit-to-stand test. Respiratory muscle strength, both inspiratory and expiratory, will be measured through mouth pressure assessments. Additionally, participants will complete a questionnaire addressing components related to sarcopenia diagnosis, including questions on strength, assistance with walking, rising from a chair, climbing stairs, and incidence of falls.
