In this review, we summarize published evidence for metabolis, exercise-related changes in FA metabolism and adipokine release mtabolism adipose tissue, and their potential contribution to meyabolism cardiovascular and ,etabolism effects of physical activity.

Published data about the effects of exercise metabolidm FA composition enhzncement human AT are limited. An early studies revealed metaabolism decrease in oleic acid and increase in linoleic acid n-6 content in subcutaneous AT after Fat metabolism enhancement training Allard et al.

Published evidence suggests that physical training may contribute to a preferential metbolism of some FAs from AT.

Already after 2 netabolism of enhwncement training in senior oarsmen, the authors observed a significant decrease in total serum triacylglycerols and cholesterol, along with changes in the FA profile of AT: a decrease in palmitoleic acid and an increase in stearic acid content, comparing to previously untrained controls Danner et al.

A more recent study demonstrated that 6 months of increased physical activity contributed to a significant increase in n-6 in overweight elderly subjects, while no such effect was observed in untrained controls Sjögren et al. Taken altogether, this sparse evidence from human suggests that chronic exercise may contribute to a decrease in content, with concomitant increase in n-6 and Since is the main FA found in triacylglycerols Ntambi and Miyazaki, ; Liu et al.

However, regular exercise training seems to reduce systemic inflammation Görgens et al. More data in this matter originate from rodent models, and based on this evidence we may compare the effect of exercise on FA composition in various WAT depots, as well as in BAT May et al.

Most of the animal studies demonstrated that chronic exercise contributed to a decrease in MUFA content, which is consistent with the observations made in humans Nikolaidis and Mougios, Regarding polyunsaturated FAs PUFAsmost animal studies showed an increase in their content, especially n-6 PUFAs; however, in some studies, the post-exercise levels of PUFAs were lower than prior to the exercise or remained unchanged.

The chronic exercise-induced changes in PUFA content in AT are depot-specific Bailey et al. Petridou et al. Among the MUFAs of visceral fat, chronic exercise contributed to a decrease inbut not in Petridou et al. In recent study conducted by May et al.

The study demonstrated that while the exercise contributed to a significant increase in MUFA level and a significant decrease in PUFA content in WAT phospholipids, an inverse phenomenon, i. Moreover, a significant decrease in triacylglycerol content of SFAs, MUFAs and PUFAs in BAT and triacylglycerol content of PUFAs in WAT was observed May et al.

However, it should be stressed that in that study, FA content was expressed in nmol per mg of protein, rather than as a percentage of total FAs as in previously mentioned experiments.

These findings suggest that post-exercise changes in FA composition of AT are not only depot- but also lipid molecule-specific. In both WAT and BAT, physical exercise contributed to a significant decrease in the total content of triacylglycerols, but with a concomitant increase in the level of triacylglycerols containing long-chain FAs 58—60 total carbons May et al.

The effects of exercise on FA composition in AT and other AT parameters in human and animal studies is summarized in Table 1. Table 1. The summary of effects of exercise on adipose tissue metabolism and adipokine secretion. The post-exercise decrease in triacylglycerols content in AT is with no doubt a consequence of enhanced lipolysis.

The process, initiated by adipose triglyceride lipase ATGLis then continued by hormone-sensitive lipase HSLupon phosphorylation thereof; eventually, the last FA chain is hydrolyzed by monoacylglycerol lipase MAGL Chen et al.

While the rate of lipolysis is decreased by obesity and high-fat diet, chronic exercise was shown to normalize the markers of this process, phosphorylated HSL and ATGL, in mice that have been previously maintained on a high-fat diet Chen et al.

Surprisingly, however, Holland et al. In contrast, chronic exercise was shown to stimulate the activity of lipolytic enzymes in the adipocytes of obese mice Woo and Kang,and a recent study demonstrated that endurance exercise contributed to an increase in triacylglycerol lipase activity in human AT, especially during the first 10 min of the training Petridou et al.

An upregulation of HSL after chronic exercise was also mentioned in a review paper published by Steinberg Moreover, irisin, an adipokine released by working muscles, was shown to induce the expression of ATGL and HSL in 3T3L1 adipocytes Gao et al.

Physical activity may also modulate FA synthesis, desaturation and elongation. The reduction of MUFA content after chronic exercise reported by many authors might be a consequence of a decrease in FA desaturation by SCD1 Nikolaidis and Mougios, However, this conclusion is based on the desaturation indices calculated from SFA and MUFA contents in AT.

Thus, it cannot be excluded that those parameters were also influenced by preferential uptake and release of certain FAs in AT during exercise Halliwell et al. One study demonstrated that chronic exercise did not affect the expression of SCD1 in mice subcutaneous WAT, but contributed to lesser activity of this enzyme in BAT May et al.

Also in human subcutaneous AT, the expression of SCD1 gene remained unchanged after the chronic exercise Sjögren et al. Published data about the exercise-induced changes in the activity of other lipogenic enzymes are inconclusive.

According to May et al. Similarly, a 6-week exercise resulted in an increase in ACC protein level in visceral WAT of rats Holland et al. In contrast, Rocha-Rodrigues et al. The same study demonstrated a post-exercise increase in the expressions of enzymes involved in PUFA metabolism, FA desaturase 1 and elongase 5 Rocha-Rodrigues et al.

In line with those findings, May et al. Taken altogether, the abovementioned findings suggest that the effect of exercise on the expression of enzymes involved in lipid metabolism may vary depending on FA group and AT depot. Muscle work during the exercise may activate a signaling cascade; specifically, myokines released from the muscle cells may trigger a release of adipokines, signaling molecules synthesized in the AT.

Aside from the production of adipokines, AT can also synthesize many myokines, among others IL-6, MCP1, TNFα, visfatin and myostatin, which are collectively referred to as adipomyokines Görgens et al.

Thus, plasma level of adipomyokines does not necessarily reflect solely the pool which is synthesized in the AT and acts on the muscles, and the origin of each molecule should be identified at a cellular level. Adiponectin is an insulin-sensitizing hormone that enhances FA oxidation in the muscles and downregulates the synthesis of lipids and glucose in the liver Swierczynski and Sledzinski, The evidence from both human and animal studies analyzing the effects of exercise on serum adiponectin level is inconclusive; chronic exercise was either shown to increase the serum concentration or expression in AT of this adipokine or did not affect it at all Kato et al.

Available data imply that the release of adiponectin from human AT may depend on exercise intensity Görgens et al. Another adipokine, leptin, is synthesized primarily in the AT, regulates appetite and boosts peripheral metabolism Swierczynski and Sledzinski, Chronic exercise was shown to contribute to a decrease in serum leptin concentration, but this effect was associated with the reduction of AT mass Lehnig and Stanford, However, previous studies demonstrated that excess body weight was associated with leptin resistance Swierczynski and Sledzinski,and chronic exercise might improve leptin sensitivity Kang et al.

Thus, the simultaneous reduction of serum leptin level and AT mass does not necessarily correspond to a decrease in the activity of this adipokine. Serum concentration of IL-6, acting as an anti-inflammatory myokine, was shown to increase substantially after acute exercise, and this effect was demonstrated to result from local synthesis of IL-6 by the working muscles.

However, the level of IL-6 after chronic exercise was decreased or remained unchanged Görgens et al. Also, the expression of IL-6 in the AT did not change or was reduced, depending on the type of chronic exercise Bruun et al. Generally, moderate chronic exercise seems to be associated with a decrease in the release of pro-inflammatory cytokines, such as TNF-α, leptin and MCP-1, from the AT and working muscles; this may contribute to attenuation of systemic inflammation Görgens et al.

A recent study demonstrated that chronically exercised rats showed enhanced expression of apelin, an adipomyokine that decreases insulin resistance Kazemi and Zahediasl, Apelin induced glucose uptake by AT, but at the same time decreases triglyceride amounts in mouse AT and lipid storage in 3T3-L1 preadipocytes Indrakusuma et al.

Also, serum concentration of resistin, an adipokine promoting insulin resistance, was shown to decrease in rats subjected to an chronic exercise Shirvani and Arabzadeh, Altogether, these findings suggest that chronic exercise may improve the profile of adipokines released from the AT, and thus, may be beneficial for health.

Aside from the metabolic processes discussed above lipolysis, FA uptake, FA synthesisFAs are also oxidized in mitochondria, in a process referred to as β-oxidation. A number of previous studies demonstrated that chronic exercise enhanced mitochondrial activity in visceral and subcutaneous AT, in both rodents Stallknecht et al.

The process of mitochondrial β-oxidation in the AT is not as intensive as in the muscles but still can provide an extra pool of energy for adipocytes after the exercise. Furthermore, there is one AT depot that shows greater mitochondrial activity than visceral and subcutaneous WAT; this is BAT which contains numerous mitochondria whereby FAs undergo oxidization, becoming a source of energy for thermogenesis.

Allison, D. The use of areas under curves in diabetes research. Diabetes Care 18 , — In fasted mice, the PHD3-dependent chemical modification to ACC2 was significantly reduced in skeletal and heart muscle, compared to fed mice. By contrast, the AMPK-dependent modification to ACC2 increased.

Next, the researchers explored the consequences when PHD3 activity was inhibited, using genetically modified mice that do not express PHD3.

Because PHD3 is most highly expressed in skeletal muscle cells and AMPK has previously been shown to increase energy expenditure and exercise tolerance, the team carried out a series of endurance exercise experiments.

To investigate, the team trained young, PHD3-deficient mice to run on an inclined treadmill. They found that these mice ran significantly longer and further before reaching the point of exhaustion, compared to mice with normal PHD3.

These PHD3-deficient mice also had higher oxygen consumption rates, as reflected by increased VO2 and VO2 max. After the endurance exercise, the muscles of PHD3-deficient mice had increased rates of fat metabolism and an altered fatty acid composition and metabolic profile.

The PHD3-dependent modification to ACC2 was nearly undetectable, but the AMPK-dependent modification increased, suggesting that changes to fat metabolism play a role in improving exercise capacity.

These observations held true in mice genetically modified to specifically prevent PHD3 production in skeletal muscle, demonstrating that PHD3 loss in muscle tissues is sufficient to boost exercise capacity, according to the authors.

The research team also performed a series of molecular analyses to detail the precise molecular interactions that allow PHD3 to modify ACC2, as well as how its activity is repressed by AMPK.

The study results suggest a new potential approach for enhancing exercise performance by inhibiting PHD3. While the findings are intriguing, the authors note that further studies are needed to better understand precisely how blocking PHD3 causes a beneficial effect on exercise capacity.

In addition, Haigis and colleagues found in previous studies that in certain cancers, such as some forms of leukemia, mutated cells express significantly lower levels of PHD3 and consume fats to fuel aberrant growth and proliferation.

Efforts to control this pathway as a potential strategy for treating such cancers may help inform research in other areas, such as muscle disorders.

It remains unclear whether there are any negative effects of PHD3 loss. To know whether PHD3 can be manipulated in humans—for performance enhancement in athletic activities or as a treatment for certain diseases —will require additional studies in a variety of contexts, the authors said.

It also remains unclear if PHD3 loss triggers other changes, such as weight loss, blood sugar and other metabolic markers, which are now being explored by the team.

Additional authors on the study include Haejin Yoon, Jessica Spinelli, Elma Zaganjor, Samantha Wong, Natalie German, Elizabeth Randall, Afsah Dean, Allen Clermont, Joao Paulo, Daniel Garcia, Hao Li, Olivia Rombold, Nathalie Agar, Laurie Goodyear, Reuben Shaw, Steven Gygi and Johan Auwerx.

Cortisol is a hormone that helps regulate appetite. In , researchers found unusually high cortisol levels in people with disordered eating.

The body releases cortisol in times of stress. However, the authors of a small study found no evidence linking resting metabolic rate and anxiety. Stress could also have an indirect impact by affecting eating patterns and sleep, both of which can alter the rate of metabolism. Why does stress happen, and how can I manage it?

People who have less sleep may have a lower metabolic rate, according to research from The study took place in a sleep laboratory, and participants slept 4 hours per night for 5 nights followed by one night of 12 hours sleep. Their metabolic rate fell after the nights with little sleep but returned to their usual levels after the night of recovery sleep.

The authors believed the body reduces metabolic rate to conserve energy when a person sleeps less. They noted this could lead to weight gain in people who do not get enough sleep.

The need for sleep varies between individuals, but the Centers for Disease Control and Prevention CDC recommend that adults aged 18—60 should have at least 7 hours per night.

What should you do if you have trouble sleeping? The results of a rodent experiment from suggested that a low intake of various B vitamins could impact the rate at which the body metabolizes lipids, including cholesterol and triglycerides.

More research may be needed to understand the relationship between vitamins, metabolism, and weight loss. A complete guide to B vitamins, types, sources, and more. Some research has suggested that eating spices such as chili, which contains capsaicin, can increase metabolic rate, including the rate at which the body burns fat and uses energy.

A study from China found that people who ate spicy food every day were more likely to have a high body mass index BMI than those who did not. The researchers noted that more investigations are needed to find out why this happens.

The Academy of Nutrition and Dietetics says that while eating hot chilies might boost metabolic rate temporarily, it is unlikely to have a significant impact. What are some healthy herbs and spices? Thyroid hormone stimulates the production of substances that increase oxygen consumption, respiration rate, and body temperature.

This involves a higher rate of energy consumption. Conversely, the body of a person with hypothyroidism is likely to burn energy at lower rate. Their metabolic rate may be slower, and they may have a higher risk of weight gain and obesity. For those with hypothyroidism, taking medications that increase the levels of thyroid hormone can increase their resting metabolic rate.

Seeking help for hypothyroidism can help speed up metabolic rate and reduce the risk of complications linked to this condition. What is hypothyroidism and how can you recognize it?

Metabolic rate refers to the rate at which the body uses energy and burns calories. The body uses most of its energy this way. Metabolic rates vary widely between individuals, so it is not possible to specify a standard or high metabolic rate. However, the higher the rate, the quicker a person will use the energy they take in from food, which may reduce the chance of weight gain.

It is not always possible for a person to change their metabolic rate, but exercise and dietary measures may help. A good metabolic rate may help with weight management.

But for those seeking to lose weight, it is better to focus on eating a varied diet with plenty of whole foods and being physically active. While some foods, such as spices, may help boost rates temporarily, they are not a long term solution.
