Fitness Testing in the XXXX Diagnosis: The al-  ndalus Project.

@entity1 @entity239
PURPOSE: This study aimed to determine the ability of a set of physical fitness tests to discriminate presence or absence of @entity239 in @entity1 . METHODS: The sample comprised 487 @entity1 with @entity239 (52.1    8 yr) and 250 control @entity1 (49.3    9 yr). We assessed physical fitness using the arm curl, 30-s chair stand, handgrip strength, 8-ft up and go, 6-min walk, chair sit and reach, and the back scratch tests. The revised @entity239 impact questionnaire was used to assess @entity239 severity and symptomatology. RESULTS: @entity1 with @entity239 performed worse than control @entity1 in all the fitness tests studied (all, P < 0.001). The receiver operating characteristic analysis showed that all the fitness tests were able to discriminate between presence and absence of @entity239 (all, P < 0.001). The area under the curve ranged from 0.708 to 0.910 (all, P < 0.001). Among the fitness tests studied, the arm curl test, followed by the 30-s chair-stand and handgrip strength tests, showed the highest capacity discriminating between the presence and absence of @entity239 . An arm curl test score of <20 repetitions was associated with increased odds of having @entity239 (odds ratio (OR), 35.6; 95% confidence interval, 12.6-101) in @entity1 age 35-44 yr. An arm curl test score of <16 repetitions was associated with increased odds of having @entity239 (OR, 23.7; 95% confidence interval, 10.3-54.0) in @entity1 age 35-44 yr. In the group of @entity1 age 55-65 yr, the highest OR was observed for the handgrip strength test and the odds of having @entity239 was 17 times greater than that in @entity1 who performed less than 19 kg. CONCLUSIONS: The arm curl, 30-s chair stand, and handgrip strength tests powerfully discriminated @entity1 with @entity239 from healthy @entity1 . Identification of @entity1 who fail to meet the suggested standards can help to easily, quickly, and cheaply rule out the presence of the disease, especially in primary care settings.
