Scientific title | Effect of resistance exercise on plasma interleukin 6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha), knee extensor muscle strength and functional capacity in older women: a single-blind randomised controlled cross-over trial |
Study objectives | The overall aim of the present study is to assess the impact of a programme of exercises performed with 75% of 1RM for ten weeks, on the plasma levels of interleukin 6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha), knee extensors muscle strength and functional capacity of community-dwelling older women, particularly in those classified as pre-frail. The specific research questions are: 1. What are the effects of a programme of ten-weeks of resistance training on muscle strength, IL-6, TNF-alpha and functionality? 2. Is there an association between knee extensor muscle strength and the plasma levels of IL-6 and TNF-alpha in pre-frail older women, evaluated after a ten-week resistance training programme? 3. Variables: Do knee extensor muscle strength and plasma levels of IL-6 and TNF-alpha influence the functional capacity in pre-frail older women evaluated after a ten-week resistance training programme? 4. Is there a change in knee extensor muscle strength, plasma levels of IL-6 and TNF-alpha and functional capacity in pre-frail older women after a ten-week resistance training programme? |
Ethics approval(s) | Ethics Committee for Research, Federal University of Minas Gerais (Universidade Federal de Minas Gerais [UFMG]) approved on the 5th December 2007 (ref: ETIC 321/2007) |
Health condition(s) or problem(s) studied | Knee extensor muscle strength/functional capacity in older women |
Intervention | The subjects will participate in a strength training programme three times a week, lasting 60-minute each session, for 10 weeks. Two major muscle groups (knee extensors and flexors) will both be trained in three sets of eight repetitions, at 75% of 1RM. Each participant will be tested at baseline, after the end of the training programme and 10 weeks after programme completion. Every training session starts with ten minutes of warm-up and ends with ten minutes of cool-down. Bi-weekly, the 1RM test is repeated to guarantee the correct percentual, in case of gains. The exercises are done with ankle weights. One group will be evaluated, will receive the intervention and then, after ten weeks, will be evaluated again. Another group will be evaluated, will maintain their regular activities during ten weeks when they will be evaluated again, and then will start the intervention as in the first group (cross-over). |
Intervention type | Other |
Primary outcome measure | Plasma levels of IL-6 and TNF-alpha measured by enzyme-linked immunosorbent assay. All primary and secondary outcomes will be assessed at baseline (before intervention), after intervention and 10 weeks post-intervention. |
Secondary outcome measures | 1. Static and isokinetic muscle strength of the knee extensors and flexors measured electronically by Byodex 3 Pro (Biodex Medical System, USA) 2. Functional capacity, measured by the 10-meter walk test and the Timed Up and Go test (TUG) 3. Clinical outcomes (pain, fatigue and self-perceived health) All primary and secondary outcomes will be assessed at baseline (before intervention), after intervention and 10 weeks post-intervention. |
