Performance analysis of women over 55 years on abdominal tests: impact of anthropometry and flexibility

The objective of the present study was to evaluate the effect of anthropometric variables and flexibility on the performance of women aged 55+ years on abdominal test protocols. The sample was composed by 20 physically active volunteers, aged 55 years (median 61), who were participants in gymnastic activities program. Each volunteer performed two abdominal tests: partial trunk flexion with a 7.6 cm sliding of the hands (P1) and partial flexion of the trunk with the hands on the thighs (P2), both executed with the feet resting on the ground. For analysis, the number of correct executions (final position) was considered in each test, as recommended by the authors. Measurements of body mass, flexibility, height, waist and hip perimeters, subjective perception of exertion, and calculations of body mass index and waist-hip ratio were performed. The perception of abdominal effort, and discomfort or pain in the cervical and lumbar region were also evaluated. The results showed that there were no statistically significant associations between the analyzed indicators (Age: P1: rs = -0.024, p = 0.916; P2: rs = -0.194, p = 0.407; BMI: P1: rs =-0.064, p = 0.792; P2: rs = -0.235, p= 0.327; Waist Circumference: P1: rs = -0.143, p = 0.563; P2: rs = 0.027, p = 0.908; Flexibility: r s= -0.327, p = 0.169; P2: rs = 0.0009, p = 0.991; Hip waist ratio: P1: rs = -0.209, p = 0.371; P2: rs = 0.217, p = 0.353) and the performance on the tests. In addition, 35% of the participants made valid attempts on P1 while 45% produced at least one valid attempt on P2. It was concluded that both abdominal tests were adequate for the studied sample and they can be applied to adult and elderly women to assess their abdominal musculature.
