Misconceptions about Strength Exercise among Older Adults

Abstract

The purposes of this study were to determine current opinions of strength exercise among older adults and whether knowledge of recommended protocols differs between strength-exercise participants and nonparticipants. One hundred twenty-nine older adults (77.5 +/- 8.6 years) responded to questions about their opinions, experiences, and knowledge of strength-exercise recommendations. Some misconceptions were identified in the sample, with 48.4% of participants responding "no" to "strength training increases muscle mass," 45% responding "no" to "increasing weight is more important than number of repetitions for building strength," and 37% responding that walking is more effective than lifting weights at building muscle strength. The number of correct responses was related to the number of years in school (semipartial r(2)= .046). More education is needed about the benefits and recommendations to ensure proper use of current strength-exercise protocols among older adults.
