EFFECTS OF ECCENTRIC TRAINING ON LOWER LIMB FLEXIBILITY – 2014


BACKGROUND
– Hypothesis: Eccentric training is an effective method of increasing lower limb flexibility
RESULTS
– From all 6 trials in 3 different muscle groups eccentric training can improve lower limb flexibility, as assessed using either joint ROM or muscle FL

AIM
– Examine age-related differences in flexibility of older adults aged 55–86 yrs of varying activity levels
RESULTS
Shoulder Abduction:
(1) Significant decline averaging 5°/decade in men and 6°/decade in women
(2) Accelerated decline in men starting at 71 yrs of 0.80°/yr; in women onset of decline (0.74°/yr) was 63 yrs
(3) Age was significant but not physical activity, in a model that described 8% of the variance for both sexes
Hip Flexion:
(1) Men and women showed significant decline (men: 6°/decade; women: 7°/decade)
(2) Rate of decline of 1.16°/year beginning at 71 yrs in men and in women a single linear decline of 0.66°/yr
(3) Age and physical activity accounted for only 9% of the variance in hip flexion in women and 10% in men
(4) Age but not physical activity remained significant
CONCLUSIONS
– In generally healthy older adults aged 55 to 85 yrs, the age-related loss of flexibility appears to be small
