Diabetes type 2 is an importance public health problem affecting more than 285 million people in the world. The purpose of the current review is to investigating and comparing the effect of different types of exercise on insulin sensitivity in patients with type 2 diabetes in order to make a favorable summary and provide better and more useful information in choosing the type of exercise for these patients based on the results of previous research.

In this study, articles were searched in Magiran, Google Scholar, PubMed, Science Direct, and Springer databases and 115 related articles were selected based on the desired keywords. After reviewing 115 articles, 87 articles were included in the study based on the inclusion criteria that were close to the field of physical activity and diabetes. After re-examining the articles, 28 articles were selected with the aim of examining exercise training in patients with type 2 diabetes.

By studying the selected articles, it was concluded that aerobic training through weight loss and body fat percentage, resistance training through increasing muscle volume, intense interval training through activating adenosine monophosphate-activating protein kinase (AMPK) and combined training through Improving body composition has increased insulin sensitivity in patients with type 2 diabetes.

The current review indicates that aerobic, resistance, HIIT and combined exercises (with any intensity, duration and type of exercise) increase insulin sensitivity in people with type 2 diabetes. However, it seems that combined exercises have more and more beneficial effects.

This systematic review aimed to evaluate the effects of various corrective exercises and supportive tools in individuals with genu valgum. To ensure a comprehensive review, a search for original research, review articles, and clinical trials in both Persian and English was conducted using databases such as WOS, SID, ISC, Magiran, Scopus, PubMed, and Google Scholar. The search covered publications during January 2008 to March 2023. A total of 76 relevant articles were selected based on strict inclusion and exclusion criteria, with 22 articles ultimately reviewed and analyzed regarding the effects of various corrective exercises and supportive tools on genu valgum. Findings from one study indicated that aerobic exercises had a significant impact on reducing body mass index (BMI) and the severity of genuvalgum. Other studies reported positive effects of resistance and corrective exercises on improving muscle electrical activity and knee stability. One study demonstrated that the use of orthotic insoles could significantly enhance knee joint support during stair descent. Six studies highlighted the positive effects of using orthoses, wedges, and braces in individuals with genu valgum. Conversely, one study pointed out the negative impact of these tools, citing the reduced limiting angle of the brace, increased applied forces, and, ultimately, greater injury risk. However, findings from three studies overwhelmingly supported the positive effects of using kinesiotape in individuals with genu valgum, providing optimism about the effectiveness of these interventions. In conclusion, our review underscores the promising potential of corrective exercises, particularly resistance exercises with TheraBand, and the combination of these with supportive tools such as insoles for arch support and kinesiotape. These interventions show significant promise in reducing the degree of knee valgus in individuals with genu valgum. This hopeful outlook can inspire healthcare professionals and individuals seeking evidence-based interventions for genu valgum, empowering them with the knowledge to make informed decisions about their care.

Foot pronation, as one of the prevalent foot abnormalities, can influence the biomechanics of the lower limbs. The use of various foot orthoses, including insoles and braces, is very common in eliminating this problem. The results obtained regarding the effect of orthoses on pain and biomechanics of individuals with foot pronation are different. The present review study was conducted to evaluate the effects of foot orthoses and shoes on the biomechanics of the lower limbs and balance in individuals with foot pronation. The articles were searched in Persian and Latin languages during 2004-22 in the databases of PubMed, Web of Science (WOS), Scopus, Islamic Science Citation (ISC), and Google Scholar search engine. Moreover, the types of the searched studies were original research, review studies, and clinical trials. Using keywords of Foot pronation, Foot orthoses, Medical soles, and Motion-control shoes, 52 relevant articles were selected, and 22 articles regarding the effects of orthoses and shoes on foot pronation were finally analyzed. Eight articles also reported that reducing forces imposed on the joints, absorbing shock, preventing pronation-related running injuries, and improving muscle activity occurred when using orthosis. Furthermore, 4 articles reported improving sports performance in athletes, reducing the ground reaction forces, and changing the frequency of muscle activity. Finally, 2 articles showed that motion-control shoes prevented intensifying the injury due to increased fatigue and subsequently increased mechanical loading during running. The results of the present study demonstrated that foot orthoses and motion-control shoes could have positive effects on balance, improving the activities of the lower limbs and reducing foot pronation and force imposed on the foot and lower limb joints.

Today, many people in society choose running as a general or special activity in order to improve their physical and physiological capabilities. Choosing the right shoes in endurance running can have a great impact on the athlete's performance. Physiological energy economy and maximal oxygen consumption are of particular importance not only among runners but among all athletes. Therefore, the purpose of this research is to compare VO2 Max values and physiological energy economy when using double density spike shoes compared to simple spike shoes. Current study is semi experimental. The statistical sample of the current study includes 30 runners from Ardabil city, who were organized in a group, and the parameters of physiological energy economy, maximum oxygen consumption, resting heart rate, systolic blood pressure and 1600 meters running record were measured during running with both double density spiked shoes and regular spiked shoes. Also, to analyze the data, the analysis of variance test with repeated measurements was used at a significance level of P=0.05. The results of the present study showed not statistically significant difference in the values of maximum oxygen consumption, heart rate and 1600 meters running record with two simple and double density shoes after performing 1600 meters running test. However, the systolic blood pressure values while running with double density shoes were less different than the control shoes (P<0.001). It seems that the use of double density shoes does not have much effect on maximum oxygen consumption, heart rate and physiological energy economy. Therefore, in order to receive more confidence and make a more decisive conclusion, there is a need to conduct more research.

Genu varum is one of the abnormalities of the lower limbs. The aim of the present study was to review the effect of exercise training and support tools on biomechanics of transitional movements in people with genu varum.

The present study was a review article. The search for articles in Persian and Latin was from the beginning of 2010 to the beginning of March 2023, which was done in the citation databases of WOS, ISC, SID, Magiran, Scopus, PubMed, and Google Scholar. 32 articles related to the effect of exercise training and support tools on genu varum were analyzed.

Findings of four articles related to aerobic exercises showed an increase in peak reaction forces and loading rate. Findings of six articles showed the positive effects of resistance-corrective exercises due to the improvement of balance and Q angle. Results of two articles showed a reduction in the severity of the abnormality due to the frequent use of the medical floor. Eleven articles discussed the positive effects of orthosis, braces, and wedges. Two articles indicated the increase of Q angle and balance due to the use of kinesio taping. One article demonstrated that the use of kinesio taping can reduce muscle strength. Six articles mentioned the negative effects of the exercise protocol or support tools or have not reported any significant differences.

It appears that performing resistance-corrective exercises along with the continuous use of support tools is more effective compared to performing aerobic exercises.

Pronated foot, as one of the common foot abnormalities can affect the biomechanics of the lower extremity. The purpose of the present study was to investigate the scientific research related to the application of various exercise protocols on foot pronation complications, as well as to make favorable summary and provide more appropriate information from previous research. In this study, the search for articles in Persian and Latin languages in 2019-2022 was carried out on WOS, Magiran, PubMed, Springer databases, and Google Scholar. The number of 52 related articles was selected based on the inclusion and exclusion criteria. After another review on these papers, 18 articles that evaluated the effects of training protocols on body mechanics in individuals with pronated feet were selected.

It seems that performing exercise to improve balance, strengthening the quadriceps muscles, and not change the lower extremity joints angles during activity has been effective. Therefore, it is suggested that rehabilitation professionals consider reinforcement activities in the process of recovering pronated using the principles and science practice.

Patellofemoral pain syndrome is one of the most common musculoskeletal disorders of the knee area. Previous studies have pointed to the positive effects of exercise. Therefore, it is very important to check the types of exercise protocols for the treatment of this condition. The purpose of the present study was to investigate the scientific framework of research related to the application of various exercise protocols on patellofemoral pain syndrome, as well as to make a favorable summary and provide more appropriate information from previous researches. In this review study, the search for articles in Persian and English languages in 2022 (until November) was carried out on WOS, Magiran, Scopus, Google Scholar, PubMed, and Springer databases. The keywords of patellofemoral pain syndrome, knee and knee rehabilitation were used to extract articles. 100 relevant articles were selected based on inclusion and exclusion criteria. After reviewing 100 articles, the number of 53 article titles that were close to the research title met the criteria for inclusion in the present study. After re-examining the articles, 25 articles were selected with the aim of examining the exercise protocol on patellofemoral pain.

It seems that sports exercises with the aim of strengthening the muscles around the knee joint are effective in the recovery process and reducing the pain of people suffering from patellofemoral syndrome.
