    The aim of this study was to investigate the effects of a specific protocol of resistance training on maximal strength gains, functional fitness and inflammatory biomarkers in elderly diabetics, irregularly active. The study included 51 subjects with 60 and 85 years, divided into two groups of untrained and trained elderly diabetic people: group diabetic untrained (IDNT, n=20, 6 women and 14 men) which were not subjected to physical training and diabetic group trained (IDT, n=31, 26 women and 5 men) which were subjected to resistance training (TFR). The subjects were trained three times per week for a period of sixteen weeks. The overload used in physical training program was equivalent to 50% of 1RM and 70% of 1RM, alternating weekly. Waist perimeter (WP), index, body mass index (BMI), and the waist -to-hip ratios were determined. The elderly were evaluated in several bodybuilding equipment before and after training by test by one repetition maximum (1RM). Functional fitness was assessed using a battery of tests directed motor evaluation of the elderly, which was composed of five tests: sit and reach test with the Wells’ bank, strength endurance of the arms, agility and dynamic balance, sitting-rising, single-foot balance, and ergospirometry on treadmill. Blood pressure measurements were always taken by the same person with a standard sphygmomanometer. Laboratory tests included determinations of blood glucose, insulin, lipocalin-2, adiponectin, leptin, tumour necrosis factor-alpha (TNF-alpha) and lipid assays (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol and triglyceride levels). Moreover, insulin resistance was assessed by the HOMA-IR index. Statistical analysis revealed significant differences (p<0.05) between the test and post-test in a period of sixteen weeks, for some variables. The average gain strength were 43.20% (knee extension), 65.00% (flexion knee), 27.80% (supine sitting machine), 31.00% (rowing sitting), 43.90% (biceps pulley) and 21.10% (triceps pul ley). In relation to functional fitness the results showed that exercise training improved performance in the sitting-rising test and agility and dynamic balance test. For the other physical abilities tested (flexibility, balance and aerobic capacity) the sixteen weeks of training period were not able to induce statistically significant changes for the elderly diabetics, although there was also a tendency for positive change on assessment of higher limbs strength for the trained group. Regarding laboratory tests found no statistical difference for the variables related to blood pressure, lipid and inflammatory biomarkers. The only exception occurred for analysis of lipocalin -2, which decreases after exercise training. In conclusion, the results show that the nonlinear resistance training had a positive effect on the capacity of strength and functional fitness, especially on performance in the chair stand test and agility and dynamic balance. Furthermore, the training program significantly decreased values lipocalin-2 in elderly diabetics.

    OBJECTIVE: To evaluate the effects of short-term exercise detraining on the functional fitness of older women after a 12-week water-based exercise (WE) program. METHODS: Healthy older women (trained (TR) group) were submitted to 12 weeks WE (three 45 min sessions per week) followed by a 6-week detraining period. A group of aged-matched women without any exercise training (UN group) were evaluated during the same period. The aerobic power, measured by VO2max and 800 meters performance, and the neuromuscular fitness and quality of life were evaluated. All assessments were made at baseline, after 12 weeks of training and after 4 and 6 weeks of detraining. RESULTS: No changes were found for the UN group during the follow-up study, but WE induced significant improvement in aerobic capacity, neuromuscular fitness and quality of life score. However, the upper and lower body strength, agility, flexibility, and body balance returned to UN levels (p>0.05) after 6 weeks of detraining. CONCLUSIONS: The results confirmed that 12 weeks of WE improves the functional fitness parameters and quality of life of older women. However, after a short detraining period of 4-6 weeks, the neuromuscular parameters and the quality of life score returns to baseline or untrained subject levels.
