A 12-week arm-cranking exercise program improved the antioxidant defense system in adults with chronic SCI, which may finally attenuate both lipid and protein oxidation in this population.

A 10-week training programme reduced pro-inflammatory cytokines and acute phase proteins in obese young women with Down syndrome. Long-term, well-conducted studies are still required to determine whether correction of this low-grade inflammation improves clinical outcomes of women with trisomy 21.

This study was designed to assess the influence of resistance training on salivary immunoglobulin A (IgA) levels and hormone profile in sedentary adults with Down syndrome (DS). A total of 40 male adults with DS were recruited for the trial through different community support groups for people with intellectual disabilities. All participants had medical approval for participation in physical activity. Twenty-four adults were randomly assigned to perform resistance training in a circuit with six stations, 3 days per week for 12 weeks. Training intensity was based on functioning in the eight-repetition maximum (8RM) test for each exercise. The control group included 16 age-, gender-, and BMI-matched adults with DS. Salivary IgA, testosterone, and cortisol levels were measured by ELISA. Work task performance was assessed using the repetitive weighted-box-stacking test. Resistance training significantly increased salivary IgA concentration (P=0.0120; d=0.94) and testosterone levels (P=0.0088; d=1.57) in the exercising group. Furthermore, it also improved work task performance. No changes were seen in the controls who had not exercised. In conclusion, a short-term resistance training protocol improved mucosal immunity response as well as salivary testosterone levels in sedentary adults with DS.

Recent studies have reported that obese young people with Down syndrome suffer from low-grade systemic inflammation. Whereas this condition may be improved in the general population by regular exercise, the problem has received no attention in the case of people with intellectual disability. Therefore, the authors' aim was to assess the influence of aerobic training on plasma adipokines in obese women with Down syndrome. Twenty obese young women with Down syndrome volunteered for this study, 11 of whom were randomly assigned to a 10-wk aerobic-training program. They attended 3 sessions/wk, which consisted of warm-up exercises followed by the main activity on a treadmill (30-40 min) at a work intensity of 55-65% of peak heart rate and ended with a cooling-down period. The control group included 9 women with Down syndrome matched for age, sex, and body-mass index. Fat-mass percentage and distribution were measured, and plasma adipokine levels (leptin and adiponectin) were assessed. In addition, each participant performed a maximal graded continuous treadmill exercise test. These parameters were assessed pre- and postintervention. Aerobic training produced a significant increase in participants' maximal oxygen uptake (20.2 ± 5.8 vs.23.7 ± 6.3 ml · kg-1 · min-1; p < .001), and plasma leptin levels were significantly reduced in the intervention group (54.2 ± 6.7 vs.45.7 ± 6.1 ng/ml; p = .026). Further significant correlations between plasma leptin and indices of obesity were found. In contrast, no significant changes were found in adiponectin levels (p > .05). None of the tested parameters changed in the control group. In conclusion, a 10-week training program reduced leptin levels in obese young women with Down syndrome.

Recently, there has been an increase in the use of over-the-counter (OTC) drugs. The consumption of these medicines can be unsafe, as incorrect self-diagnosis or the ingestion of inappropriate doses can lead to side effects and the occurrence of adverse reactions and drug–drug interactions. A cross-sectional descriptive observational study was carried out, targeting the entire Spanish population by using an online questionnaire. The results showed that 78.9% of the subjects had previously taken or were currently taking OTC drugs. This consumption decreased as the age of the subjects increased, with a prevalence of 36.4% of subjects aged ≥71 taking OTC drugs. Analgesics were the most consumed OTC drugs (49.1%) especially in women, youngsters with non-formal educational qualifications, and individuals of a low–medium socioeconomic level residing in urban areas. Measures should be implemented to optimize the safe use of OTC drugs in order to avoid the occurrence of secondary events associated with the lack of knowledge related to their the usage.

Previous studies have found aerobic training improved oxidative damage in people with Down syndrome (DS). However, there is a lack of information regarding the influence of resistance training on redox imbalance in this population. Accordingly, this study was conducted to determine the effect of resistance training (RT) on antioxidant defence system in sedentary adults with DS. Thirty-six male adults with DS were recruited through different community support groups. Eighteen were randomly assigned to perform a circuit RT program with 6 stations, 3 days/week for 12 weeks. Plasma total antioxidant status (TAS), reduced glutathione (GHS), ascorbate, serum α-tocopherol, and erythrocyte glutathione reductase activity were assessed. Plasma malondialdehyde (MDA) and carbonyl groups (CG) were assessed as markers of oxidative damage. Muscle strength was also measured. Dynamic torque of knee extensors and flexors as well as maximal handgrip strength was significantly improved after the completion of the training program. Plasma levels of TAS and erythrocyte glutathione reductase (GR) activity were significantly increased. Conversely, MDA and CG levels were significantly reduced. It was concluded RT improved antioxidant defence system and reduced oxidative damage in adults with DS. Further, long-term studies are required to determine whether the increased antioxidant system may improve clinical outcomes of adults with DS.
