According to the latest research of the International Diabetes Federation (IDF) (2017), 352 million of adults around 20 and 79 years old (which is 7,3% of that population), could be classified as prediabetes. It is foreseen that this number will increase to 481 million in 2040. People with prediabetes have approximately 30% of the possibility to develop diabetes mellitus type 2 (DM2) during a term of 10 years. Prediabetes is characterized by levels of glucose in blood above the normal, but levels under the diagnostic standards of diabetes type 2. Prediabetes is an intermediate phase of hyperglycemia, even though there is no general agreement about the beginning of its determination. The American diabetes Association (ADA) said that it is characterized by glucose on disturbed fast (100-125 mg/dl), tolerance to disturbed glucose (140-199 mg/dl) and/or glycosylated hemoglobin, (HbA1c) which is around 5,7% and 6,4%. The World Health Organization (WHO) indicates that the beginning of prediabetes in glucose in fast is 110-125 mg/dl2. The etiology of prediabetes is mainly the resistance to insulin of skeletal muscle, the liver and / or adipose tissue which, and by the time, promotes excessive insulin secretion of B cells and produces a pancreatic exhaustion that produces severe hyperglycemia. The resistance to insulin of skeletal muscle is the essential responsible for the intolerance to glucose (IGT, postprandial glucose at 2 h\> 140 mg/dl). On the other hand, the resistance to hepatic insulin is shown mainly as an alteration of glucose in fast (IFG; plasma glucose in fast \>100 mg/dl), this last, because the production of glucose is excessive despite normal insulinemia. There are several research which prove that diabetes has a relation cause-effect with cardiovascular illness and mortality in all vascular causes. However, it is not an unavoidable process but reversible.

Even though it is probable that prediabetes will be the result of multiple factors, the deteriorated mitochondrial function is the main factor that contributes to the etiology of resistance to insulin, a crucial sign of this illness. The intervention designed to increase oxidative capacity in adults with diabetes, therefore, could relieve resistance to insulin and improve tolerance to glucose. Physical exercise is a vital known strategy to prevent, care and control diabetes type 2 and prediabetes.

Energy deficit after high intensity exercise contributes to increasing the sensibility of insulin. In fact, an Energy deficit of about 6,5 kcal/kg of corporal weight after a series of severe exercise resulted in an increase of the area under the curve (AUC) of postprandial insulin about 22% lower during an oral glucose tolerance test (OGTT). This last, in comparison with a reduction of 11% when there is a replacement of expended calories. This suggests that approximately 50% of the effect of the exercise to insulin sensibility is the result of energy deficit because of the exercise.

The high-intensity interval training (HIIT) can increase the oxidative capacity in comparison to continuous training in healthy individuals, which suggests the variation in fat oxidation depends on the intensity. This last observation is clinically relevant since fat oxidation during exercise is directly related to insulin sensitivity. The changes included for the HIIT in the mitochondrial function can explain its greater efficiency to provoke positive metabolic adaptations in comparison with traditional training treatment protocols of resistance, even when there is no diet intervention test to lose weight. Interval training (HIIT), training with corporal weight, and functional training has emerged as some attractive options to program therapeutic exercise in the ambit of physiotherapy. This is used as a systematic way and safe in different populations, including people at chronic illness risk.

Excess weight (body mass index (BMI) ≥ 25.0 kg/m2) and obesity (BMI ≥ 30.0 kg/m2) are common contributors to pain and disability in the musculoskeletal system, especially in the female population. Excessive weight increases mechanical stress on the joints and tissues of the body and cause physical limitations and body pain. It is evident an increase of pain severity in higher body mass index (BMI) ratings. With 40% of women worldwide classified as overweight and 15% as obese, the relation between pain and BMI may evolve as a growing challenge for the health system. The evidence suggests that obesity modulates pain through several mechanisms, such as mechanical load, inflammation, and psychological state. Obesity has been associated with markers of chronic inflammation, such as C-reactive protein levels, tumor necrosis factor α, amyloid A and interleukin 6 and white blood cell counts. Therefore, the impact of obesity on various musculoskeletal conditions may be due not only to the biomechanical stress of obesity, but also to the systemic effects. The latter suggests that increased inflammation caused by obesity may play a role in pain. The increased fat index and decreased muscle mass have been significantly associated with musculoskeletal pain among women, having higher rates of physical inactivity. Pain in obesity contributes to the deterioration of physical capacity, health-related quality of life and functional dependence.

The research has shown that pain limits participation in physical activity in general. Overweight and obese women have reported that fear of pain or injury during exercise is a major barrier to a more active lifestyle, as well as an important impediment to exercise adherence. However, physical activity, and especially resistance training, can prevent or reverse pain symptoms by increasing muscle mass, muscle strength, and physical function, helping stabilize joints, improve mobility, and improve proprioception. While acute exercise can transiently exacerbate pain symptoms, regular participation in exercise can reduce the severity or prevalence of pain. Also, while published attrition rates with regular exercise are high (around 50%), exercise adherence can be improved with exercise modifications, including accumulating several sets of exercise rather than one long session, which reduces the joint's range of motion and replaces impact with non-impact activity. Regular exercise has been identified as the primary prevention against more than 35 chronic conditions, including obesity, conditions related to joint pain, anxiety, and depression. Exercise stimulation can have a positive impact on chronic pain mediators by exerting anti-inflammatory effects, increasing muscle strength and coordination, and improving psychological outlook. A study conducted to evaluate the impact of a musculoskeletal pain intervention before participating in a weight management program; the Physiotherapy intervention aimed at decreasing musculoskeletal pain in obese individuals reported that musculoskeletal pain was reduced for those who completed the program. Given these findings, it is plausible that activity deterrence is a problem in this population. In contrast, specialized musculoskeletal interventions have been shown to reduce pain and improve exercise compliance even in chronic conditions.

The improvements in physical ability could take place if the exercise program includes resistance training, to avoid poor outcomes with women's health. strength is closely related to changes in the neuromusculoskeletal system, as well as reduction in muscle mass. The inclusion of resistance exercise training in such programs can further increase performance, skeletal muscle mass, resting metabolic rate, and energy expenditure and thus improve body composition and overall health. Resistance exercise protocols that incorporate whole-body movements, which aim to activate the entire neuromuscular system, can also improve the functional ability to perform activities of daily living in people who demonstrate neuromuscular limitations and reduced mobility.

Further to these conditions, emerging evidence indicates that movement patterns that increase the risk of musculoskeletal alterations occur due to neuromuscular control deficits, which lead to compensatory motor strategies. This lack of motor control or deficit in neuromuscular function has been operationally defined as the neurological mechanisms underlying the unconscious activation of dynamic constraints that occur in preparation for and in response to joint movement. Clinically, these deficits in neuromuscular control manifest as deficits in postural control and altered peripheral muscle activation, which arises from changes in the central nervous system that adversely affect the control of the skeletal muscular system. A core abdominal muscle training program improves the biomechanics of the lower extremities and trunk. biomechanical patterns may be favorable for preventing exercise-related injuries.

Improving self-regulation skills is a critical component to physical activity interventions that aim to reduce the risk of diabetes and promote independent long-term adherence. This last is a scientific position statement by the American Heart Association and the American Diabetes Association. Within this framework, the efficacy of self-regulation is a belief that refers to the confidence to promulgate and carry out self-managing behaviors. It is critical for successful long-term participation in behaviors such as physical activity. The self-efficacy has been identified as a significant predictor of the adoption and maintenance of physical activity behavior, as a mediator of the effects of the intervention on physical activity and it has been identified as the most influential factor of behavior change within the literature on physical activity. In this way, fostering strong beliefs about social, physical, and self-assessment outcomes, through therapeutic education, have the potential to influence people's motivation to adhere to an exercise program in Physiotherapy.

Advocating for a lower volume of physical activity is of potential importance for exercise adherence, as "lack of time" is the most common cited perceived barrier to regular participation in exercise. Lack of local facilities for physical exercise, as well as the economic resources that are invested in this aspect, especially in developing countries are important obstacles for people to continue in training programs. Therefore, the recent alternative of HIIT protocols performed with body weight is gaining more and more strength.
