Multiple sclerosis (MS) is a chronic disease that affects central nervous system (CNS) – coexists in brain, spinal cord and optic nerves. It can process in three different courses: remitting, progressive and progressive-relapsing. Although there is still no cure for MS, effective strategies are available to modify the disease course, reduce number of relapses, rate of progressions and development of new lesions. Nowadays, moderate physical performance is strongly recommended: besides having positive effects on the body, it can have a positive effect on the psychophysical wellbeing. Essentially there are 3 types of training protocols: aerobic (endurance training), strength training (resistance training) and combined training. The majority of the studies suggests that regular physical activity can improve fatigue, depression and quality of life in people with MS, however most of the researchers worked without any guidelines for physical activity adapted to the MS, which are still under review by the scientific community.
Dietary supplements are extensively used among athletes as well as amateurs attending gyms. Regardless of very poorly investigated information about the effects of these products – both desirable and adverse – a wide range of population is used to take them. The aim of this study was to investigate the supplement consumption in Sicilia, Italy. An online questionnaire has been administered to 588 subjects (55% male and 45% female) aged between 15 and 53 years, frequenters and non-frequenters of gyms. The questionnaire showed that 75% of subjects practice (more or less regularly) physical activity 3-4 times a week, whilst the 25% did not practice any sport. Saline Supplements (Gatorade, Powerade, etc.), Branched Amino Acids (BCAAs) and protein supplements were the most frequently indicated dietary supplements (25.2%, 19.4% and 27%); carnitine and creatine the least (6.8% and 11.6%). Most of the practicing sport respondents administer nutritional supplements by themselves and they do not acknowledge any noticeable performance improvement. Therefore, even if there is no definite posology for the use of supplements, these should never be considered as an alternative to foods and a proper lifestyle.
