Summary
This study establishes hand grip strength reference values for the Spanish population, recommending the Jamar dynamometer over the Collin type. Grip strength is significantly associated with lean mass index, confirming its utility in nutritional assessment.
Area of Science:
- Human physiology
- Nutritional science
- Biomedical engineering
Background:
- Establishing population-specific reference values for physiological measurements is crucial for accurate health assessments.
- Hand grip strength is a key indicator of overall strength and functional capacity.
- Previous studies have highlighted the association between grip strength and nutritional status.
Purpose of the Study:
- To establish reference values for hand grip strength in the Spanish adult population.
- To compare the performance of Collin and Jamar dynamometers for grip strength measurement.
- To determine the association between hand grip strength, anthropometric measurements, and lean mass.
Main Methods:
- A cross-sectional, population-based study was conducted with 817 randomly selected adults in Pizarra, Spain.
- Hand grip strength was measured using both Collin and Jamar dynamometers on the dominant hand.
- Body composition was estimated through skinfold measurements, and lean mass index (LMI) was calculated.
Main Results:
- Significant positive correlations were found between Jamar and Collin dynamometer measurements (r = 0.782, p < 0.001).
- Hand grip strength showed significant positive correlations with lean mass index (LMI) for both dynamometers (r = 0.538, p < 0.001 for Jamar; r = 0.462, p < 0.001 for Collin).
- Individuals identified as malnourished based on LMI exhibited significantly lower grip strength compared to normally nourished individuals.
Conclusions:
- Reference values for hand grip strength in the Spanish population were established.
- The Jamar dynamometer is recommended over the Collin type due to usability issues with the latter.
- Hand grip dynamometry is a valuable tool for nutritional assessment due to its strong association with lean mass.

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.

Nurses are responsible for caring for patients during birth, death, illness, and healing. Professional values guide the decisions and actions that nurses make in their careers. If nurses know the decisions and actions to take, providing patients with exceptional care is possible.
The values that are the foundation of the nursing profession are altruism, autonomy, human dignity, and social justice.
First, altruism refers to the concern for the welfare and well-being of others without personal...

A critical value is a definite value obtained from a particular probability distribution at a predecided confidence level (or a predecided significance level) for a given population parameter. The critical value provides demarcation that separates the sample statistics that are likely to occur from the ones that are unlikely to occur based on the given probability distribution and the population parameter to be estimated. The critical value for normal distribution is obtained from the z...

The z score is one of the three measures of relative standing. It describes the location of a value in a dataset relative to the mean. z scores are obtained after the standardization of the values in a dataset. The z score for the mean is 0.
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...

Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

Newton’s first law is usually considered to be a statement about reference frames. It provides a method for identifying a special type of reference frame: the inertial reference frame. In principle, we can make the net force on a body zero. If its velocity relative to a given frame is constant, then that frame is said to be inertial. So, by definition, an inertial reference frame is a reference frame where Newton's first law holds valid. Newton's first law applies to objects with...
