Validity and reliability of the modified sphygmomanometer test for assessing upper limb and trunk muscle strength in adolescents.

The Modified Sphygmomanometer Test (MST) is a method for assessing muscle strength that offers objective measures similar to those of a portable dynamometer, while also being cost-effective. However, previous studies have not investigated the measurement properties of the MST in adolescents. Thus, the objectives of the study were (1) to examine the concurrent criterion validity, test-retest and interrater reliability of the Modified Sphygmomanometer Test (TMS) for assessing muscle strength in adolescents, (2) to calculate the Standard Error of Measurement (EPM) and the smallest real difference (SRD) of muscle strength values; and (3) analyze the different forms of operationalization and their influence on the results obtained.

Article Synopsis
- Aging can lead to sarcopenic obesity, a condition where individuals are obese while also experiencing muscle loss and decreased strength due to sarcopenia.
- The study evaluated 156 older women to analyze the effects of obesity, sarcopenia, and sarcopenic obesity on body composition, functional performance, and muscle strength; results showed that 32.7% had obesity, 15.4% had sarcopenia, and 25% were classified as having sarcopenic obesity.
- Findings revealed that women with sarcopenic obesity had worse physical performance and lower muscle-specific strength compared to those without, highlighting the need to consider muscle strength in diagnosing and addressing sarcopenic obesity in
Article Synopsis
- The study aims to explore the relationship between inflammatory biomarkers, physical function, and cognitive decline in older women, focusing on early diagnosis strategies.
- Using various tests, including the Mini Mental State Examination and physical performance assessments, it analyzed cognitive function in 71 participants.
- Key findings suggest that poorer physical function and elevated leptin levels are linked to decreased cognitive function, providing insights into the underlying causes of cognitive decline and potential strategies for intervention.
The strong inverse association between plasma concentrations of soluble tumor necrosis factor receptors type 1 with adiponectin/leptin ratio in older women.

Article Synopsis
- The study investigates the relationship between the Adiponectin/Leptin (A/L) ratio and various inflammatory biomarkers in older women, highlighting its potential as a biomarker for insulin sensitivity and cardiovascular risk.
- The research found that the A/L ratio negatively correlates with several inflammatory markers, notably brain-derived neurotrophic factor (BDNF), interleukin-8 (IL-8), and soluble TNF receptor 1 (sTNFr-1), indicating an inflammatory imbalance between muscle and fat tissues.
- The findings suggest that elevated sTNFr-1 is linked to increased inflammation that could affect muscle and adipose tissue interactions, offering insights into potential diagnostic biomarkers related to inflammation and muscle health in aging individuals.
Article Synopsis
- - Recent studies indicate that Sarcopenia, a condition characterized by loss of muscle mass and strength, affects inflammatory biomarkers, but the understanding of how these biomarkers change at different stages of the condition is limited.
- - This study involved 71 older Brazilian women, assessing muscle strength, physical performance, and body composition, and classified Sarcopenia based on the EWGSOP2 criteria.
- - Results showed that as Sarcopenia progressed, levels of specific inflammatory biomarkers (BDNF, IL-8, sTNFr-1, and sTNFr-2) increased, suggesting these could help in diagnosing and determining the severity of Sarcopenia in older women.
Prevalence of sarcopenia in older women and level of agreement between the diagnostic instruments proposed by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2).

Article Synopsis
- The study investigated the prevalence of sarcopenia among older Brazilian women using diagnostic tools recommended by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2).
- It found significant differences in sarcopenia prevalence rates based on various assessment methods, with some tools indicating rates as high as 40.6% while others showed much lower figures.
- The results highlighted a lack of agreement between diagnostic instruments, emphasizing the need for clarity in assessing sarcopenia to improve identification and management in diverse populations.
Certain cut-off points for sarcopenia screening and diagnosis are arbitrary and based on European populations, with normative references often obtained from healthy young adults. Although respiratory skeletal muscle strength tests represent low-cost clinical measures commonly performed in clinical practice by health professionals, a gap remains regarding whether respiratory skeletal muscle strength tests are adequate and sensitive measures for sarcopenia screening. This study aimed to verify the value of handgrip and respiratory muscle strength as possible discriminators to identify sarcopenia and to establish cut-off points for sarcopenia screening in community-dwelling, Brazilian women.
