Paper details:

(1) A correlational study finds that age is related to strength; as children get older, their strength increases- The researchers state that strength is caused

by increasing age- Do you agree with this statement? Why or why not- Support your answer-

While I do agree that there is a correlation between age and strength, I disagree with the statement, “Strength is caused by increasing age-” Firstly, there is

limited information regarding the study to even support this statement; it is too general- How did they define and measure strength? Secondly, does the

statement suggest that increased strength is caused by increasing age or perhaps it suggests that strength can fluctuate depending on age? At what age

does strength generally peak and begin to deplete? Surely we can use commonsense knowledge to understand that generally an elderly individual has less

strength than a fully developed 21-year old- Senden, Savelberg, Heyligers, and Meijer (2014) supported that elderly individuals encounter age-related

reduced muscle strength, which would counter the hypothesis that increasing strength is caused by increasing age-

In addition to the questions I raised above, what methods and variables were used in the study? Were extraneous variables considered to justify internal

validity? There are several, if not many, individual differences that affect one’s strength aside from age- For example, genetics- Schutte, Nederend, Hudziak,

Geus, and Bartels (2015) concluded that hereditary factors largely impact individual strength and physical ability. Schutte, Nederend, Hudziak, Geus, and

Bartels (2015) also indicated that environmental factors affect individual strength as well, such as familial influences and sports training- I would also suggest

that one’s culture would affect individual strength; for example, a culture that emphasizes manual labor over machinery work might be indicative of increased

general strength- In short, there is a correlation between strength and age: a three-year-old has increased strength over a newborn infant- However,

increasing age with strength does not provide enough evidence for a causal relationship because there are too may extraneous variables that influence

strength as well-
