Context:Overproduction of reactive oxygen and nitrogen species during physical exercise, exercise induced oxidative stress and antioxidant supplementation is interesting and controversial concepts that have been considered during the past decades.Evidence Acquisition:In this review, we aimed to summarize current evidence in relation to antioxidant supplementation outcomes during exercise and physical activity. For this aim, we obtained relevant articles through searches of the Medline and PubMed databases between 1980 to 2013. Although major studies have indicated that antioxidants could attenuate biomarkers of exercise-induced oxidative stress and the use of antioxidant supplement is a common phenomenon among athletes and physically active people, there are some doubts regarding the benefits of these.Results:It seems that the best recommendations regarding antioxidants and exercise are having a balanced diet rich in natural antioxidants and phytochemicals.Conclusions:Regular consumption of various fresh fruits and vegetables, whole grains, legumes and beans, sprouts and seeds is an effective and safe way to meet all antioxidant requirements in physically active persons and athletes.
ObjectiveThe effects of regular exercise on the health promotion of patients with type 2 diabetes mellitus (T2DM) have been well documented. The present study investigated the long-term effects of regular exercise training on biological indicators among these patients.MethodsIn this quasi-experimental trial with pretest-post-test design, 65 patients with T2DM aged 33–69 years (experiment (35), control (30)) participated. After 8 years of conducting the program, the data on 30 patients (experiment (15), control (15)) were entered into analysis. The training program included aerobic exercise three sessions per week, 90 min, 50%–80% VO2max. Before and after the intervention, the biological indicators (hemoglobin A1c (HbA1c), body mass index (BMI) and VO2max) were measured. Data were analyzed using multivariate analysis of covariance.ResultsOur long-term exercise training program had a significant effect on HbA1C, BMI and Vo2max (P<0.05). Compared with patients in the control group, HbA1c was significantly reduced and BMI and VO2max were significantly improved among the experiment group.ConclusionsLong-term regular physical activity training was found to be helpful in improving glycemic control, body composition and cardiovascular fitness among patients with T2DM. Long-term continuous physical activity offsets the deteriorations of biological indicators found in the control group. Further research, with a particular focus on practical and real-world programming, is needed to determine the responsive health outcomes of such long-term programs on the patients.
ObjectiveThe aim of this study was to document long-term symptoms and functional results following war-related knee disarticulation, trans-femoral amputation, and hip disarticulation.MethodsAn observational cross-sectional study was conducted in a 7-day recreational camp in Iran. One thousand patients with unilateral hip disarticulation, trans-femoral amputation and knee disarticulation due to war-related injuries were invited to undergo a thorough physical examination. Among the invited persons, 58.7% (587 subjects) responded to our invitations. A complete examination related to phantom pain, phantom sensation, stump pain, back pain, and sound limb joints pain with a self-constructed questionnaire was performed. In addition, Amputee Mobility Predictor (AMP) instrument with a prosthesis was completed to assess the function of patients.ResultsThe mean duration of time since amputation was 22 years. The most common symptoms reported by participants were phantom sensation (82%), back pain (69%), and phantom pain (63%). In addition, total scores of AMP with a prosthesis in persons with knee disarticulation and trans-femoral amputations were 20.8 and 28, respectively.The knee disarticulation was associated with higher scores of AMP with a prosthesis compared to transfemoral amputation (p < 0.01).ConclusionThe results of this study showed that patients with lower limb amputation suffer from significant clinical and functional problems. The findings may be useful to adopt new strategies in planning rehabilitation programs to improve quality of life and health status of patients with war-related lower limb amputation.Level of EvidenceLevel IV, Therapeutic study.
BackgroundThe aim of the study was to identify health concerns of veterans with high-level lower extremity amputations.MethodsThrough a cross-sectional study, general practitioners, an orthopedic specialist, psychologists, psychiatrists, physiotherapist and prosthetists examined 100 veterans using a short-form health-related quality of life questionnaire (SF-36) that assessed their ability to perform activities of daily living (ADL), instrumental activities of daily living (IADL) and life satisfaction (SWLS) after hip disarticulation or hemi-pelvectomy amputations. The assessment tool was designed to gather statistically useful information about their health needs.ResultsThe means of the Physical Component Summary (PCS), Mental Component Summary (MCS), SWLS, ADL and IADL were 48.58 ± 29.6, 33.33 ± 22.0, 19.30 ± 7.7, 48.10 ± 10.5 and 5.08 ± 1.8, respectively. Somatization, depression, and anxiety were the most prevalent disorders; among the veterans who were visited by psychiatrists, 11.6% had a history of hospitalization in a psychiatry section, and 53.2% had a psychiatric visit. Regardless of their injury in battle, 34% of veterans were hospitalized. Hearing problems were common, and about four-fifths of the participants suffered from at least one orthopedic condition. Neuroma (49%) was the most common stump-related complication during orthopedic evaluations, though the prevalence of phantom pain was 81% during the pain assessment. A total of 87% of the participants had a history of wearing a prosthesis, but only 29% wore a prosthesis at the time of the present study. The Canadian-type of prosthesis was uncomfortable and not useful (27%) and excessively heavy (10%) according to the amputees.ConclusionsUnderstanding veterans’ characteristics and special needs are important to make sure that enough facilities and services are afforded to them. These findings emphasize the importance of paying close attention to different dimensions of health in veterans and can help health providers identify health needs and make regular assessments.
