Among the physical health measures , RT had the largest effect on body pain ( ES=0.81 , 95 % CI : 0.26 - 1.35 , I2=85.9).Initially , RT did not significantly affect measures of emotional role function , social function or physical role function .
However , after removing a single study , RT significantly increased all HRQOL measures .
Conclusion : The meta-analytic evidence presented in this research clearly supports the promotion of RT in improving HRQOL in older adults
Background : Resistance training ( RT ) is recommended as part of our national physical activity guidelines which includes working all major muscle groups on two or more days a week .
Older adults can gain many health benefits from RT , such as increased muscle strength , increased muscle mass , and maintenance of bone density .
Additionally , certain dimensions of health-related quality of life ( HRQOL ) have been shown to improve in older adults due to RT intervention .
The purpose of this study was to use systematic review and meta-analytic techniques to examine the effect of RT on HRQOL in older adults .
The PEDro scale is a valid measure of the methodological quality of clinical trials: a demographic study.
QUESTIONS Does the PEDro scale measure only one construct ie , the method ological quality of clinical trials ? What is the hierarchy of items of the PEDro scale from least to most adhered to ? Is there any effect of year of publication of trials on item adherence ? Are PEDro scale ordinal scores equivalent to interval data ? DESIGN Rasch analysis of two independent sample s of 100 clinical trials from the PEDro data base scored using the PEDro scale . RESULTS Both sample s of PEDro data showed fit to the Rasch model with no item misfit . The  PEDro scale item hierarchy was the same in both sample s , ranging from the most adhered to item r and om allocation , to the least adhered to item therapist blinding . There was no differential item functioning by year of publication . Original PEDro ordinal scores were highly correlated with transformed PEDro interval scores ( r = 0.99 ) . CONCLUSION The PEDro scale is a valid measure of the method ological quality of clinical trials . It is valid to sum PEDro scale item scores to obtain a total score that can be treated as interval level measurement and subjected to parametric statistical analysis
