with those 71 years old,whereas inwomen the onset of decline
was 63 years and declined across age at a rate of 0.74 degrees
per year (Figures 1(a) and 1(b)).
3.3.2. Hip Flexion. The women had significantly higher hip
flexion of 114 degrees versus the men, with 102 degrees.
However, both showed a similarly significant age-related
decline in hip flexion (men: 6 degrees per decade; women:
7 degrees per decade). Piecewise linear regression revealed a
rate of decline of 1.16 degrees per year, across age, beginning at
71 years in men (Figure 2(a)). In women, the decrease across
the age span of the sample was a single linear decline of 0.66
degrees per year (Figure 2(b)).
3.4. Relationship of Age and Physical Activity with Flexibility.
Both upper and lower body flexibility measures were
normally distributed. Age was significant (
