To counter insulin resistance, it is essential to augment the consumption pace of fatty acids in blood and adipose tissue. The purpose of the study is to conclude the relation between metabolic reaction and exercise period from alteration in the respiratory exchange ratio (RER). The mean RER during 30 minutes of temperate exercise (mean pulse 115 beats/min) was 0. 89 +/- 0. 02, signifying no key variation.

Important changes were pragmatic in the levels of plasma glucose (PG), plasma free fatty acid (FFA), and plasma immunoreactive insulin (IRI) before and after exercise, indicating a reduction in PG and IRI, and an enhancement in FFA levels. However, the RER rate designated that carbohydrate was the main metabolic substrate; consequently, protracted or recurring short and gentle to reasonable exercise is important to raise the consumption of fatty acids.

Much research has been carried out on the usefulness of exercise rehabilitation for lifestyle-related illnesses linked with insulin struggle such as diabetes, hypertension, hyperlipidemia, and obesity. To reduce insulin resistance, it is essential to enhance the consumption pace of fatty acids in blood and adipose tissue). Long-term fairly concentrated exercise at 50% of maximal oxygen utilization has been suggested for both obese and non-obese subjects), as it has been known that fatty acids cannot be used for muscle power after an exercise of short time).

Nonetheless, a constructive association has been accounted for between the improvement of insulin resistance and the number of steps walked per day), which proposes that mounting the amount of collective exercise is more imperative than the period of exercise in improving insulin resistance). Thus, it might be hypothesized that fatty acids are accessible for energy after a short-range exercise. Critique Exercise is very important for health. Regular exercise, everyday ensures the proper flow of blood and sweating, which releases the toxins from the body.

Exercise also raises the heartbeat, thus causing more blood to be pumped to the heart. Diabetes is one disease where the fatty acids that consume the normal production of insulin in the body are broken down and dissolved by exercising. Exercise helps break down these fatty acids in the body and the right amount of insulin then absorbs them into the body. People with diabetes should exercise regularly to burn the fatty acids faster. However, there are some conditions where exercise can be fatal and people should consult their physicians before they embark on an exercise regimen.

As exercise intensity and duration increase, the catecholamine and glucagons levels increase and insulin levels decrease. This is accompanied by an increase in plasma FFA levels, which is related to higher lipid utilization in muscle and lipolysis in adipose tissues). In the study a significant decrease in IRI and an equally significant increase in FFA levels were observed. In the present study, during moderate exercise for 30 minutes the RER value indicated that carbohydrate was the dominant metabolic substrate.

Recently people seem to be always very busy and have few chances to engage in pro-longed physical exercise. In these cases, repetition of short-term physical exercise should be carried out on a regular basis. As already shown in this study, fatty acids can be utilized even during mild short-term physical exercise. In conclusion, the present study suggests that an increase in the cumulative amount of brief and mild to moderate exercise is important for both the prevention and treatment of lifestyle-related diseases involving insulin resistance.

Carbohydrate and lipids are used as energy sources during endurance exercise, and the pro-portion of carbohydrate and fatty acids used depends on the intensity and the duration of the exercise). Fatty acid utilization is known to increase in endurance exercise, continuing for more than 90 minutes), whereas during exercise below the level of 50% the maximum utilization of carbohydrate and fatty acids is roughly the same. To prevent and/or reduce insulin resistance, it is necessary to increase the utilization of fatty acids in adipose tissue and blood.

Exercise intensity should be moderate or lower. If exercise is continued for a long duration, the respiratory quotient is known to gradually de-crease with exercise time due to a decrease in the amount of stored carbohydrates. There is considerable uptake of the plasma glucose by the muscles during exercise, but since there is also an increase in the release of glucose from the liver, there is little decrease except when the exercise continues for a long time. In the study a slight decrease in the plasma glucose was observed following 30 minutes of exercise.

Even a repetition of a short-term exercise could increase the rate of fatty acid metabolism. Under fasting conditions, obese subjects with insulin resistance have an elevated leg respiratory quotient and reduced fat oxidation. Therefore, it becomes necessary for obese subjects to perform mild physical exercise for a long time. There is considerable uptake of the plasma glucose by the muscles during exercise, but since there is also an increase in the release of glucose from the liver, there is little decrease except when the exercise continues for a long time.
