Objective:
This study aimed to investigate the relation among farming activities, muscle strength, and body composition in middle-aged and older adults.
Patients And Methods:
Participants aged ≥40 years were recruited from three health-related events in Nagoya City, Japan. A questionnaire was used to collect information on basic characteristics and daily activities, and grip strength, body weight, and body composition were assessed.
Results:
The study included 126 participants (42 in the farming activity group and 84 in the nonfarming activity group) with a mean age of 60.4 ± 12.5 years, of whom 65.9% were women. A decline in skeletal muscle percentage was significantly associated with aging, regardless of farming activities. Lower grip strength was significantly associated with aging in the nonfarming group but not in the farming group.
Conclusion:
The findings of this study suggest that farming activities may be associated with the maintenance and improvement of muscle strength.

Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
Strength of Cement
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...
Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
