Such considerations may also be applicable for non-athletes who could regularly perform relatively intense endurance exercise and thus actively maintain or protect aging induced reductions in aerobic capacity.
Other physiological evidence counters the epidemiological evidence that sedentary behavior dictates adverse outcomes. Moreover comparison of insulin sensitivity levels to physical activity and sedentary behavior found that indeed, those who were most sedentary had the lowest insulin sensitivity 2.
However, a subset of individuals maintained higher insulin sensitivity through a small volume of high intensity movement despite being more sedentary 2. Because of the clear and reproduced evidence that maximal aerobic capacity is a powerful predictor of disease and mortality risk during aging 4 , 19 , it appears that simply reducing sedentary behavior would not result in more favorable outcomes, but rather that regular physical activity in order to improve aerobic capacity might be required to provide beneficial effects on morbidity and mortality.
In summary, clinical trials are clearly needed to determine if traditional exercise training impacts the detrimental effects of excessive sedentary behavior and if reducing sedentary behavior and increasing physical activity is enough or if elevating or maintaining aerobic capacity is needed for maximal health. It is very likely that the answer to these recommendations may be outcome specific.
Rationale In invertebrate and vertebrae models caloric restriction increases longevity. Recent evidence in Drosophila suggests that the effects of caloric restriction may be dependent on a threshold level of daily activity or alternatively, an avoidance of sedentary behavior Also, a threshold level of activity is needed to maintain proper control of dietary intake However, energy restriction may be accompanied by decreases in energy expenditure by physical activity.
Further, maintaining aerobic capacity throughout the lifespan is associated with reduced early mortality and disease risk and maintenance of aerobic capacity would be dependent on avoiding a totally sedentary lifestyle 7 , 8. New data provide evidence that periods of relative energy deprivation followed by repletion, or energy cycling, are more advantageous for stem cell function than constant periods of excess caloric availability or deprivation fasting or caloric restriction 9 , Thus, avoiding chronic sedentary behavior and subsequently increasing physical activity may provide advantages of improved stem cell health, repair and immune surveillance in addition to overall improved caloric balance.
Evolutionary reasoning suggests that our genes and metabolic pathways evolved and were selected during conditions in which avoidance of chronic sedentary behavior and obtainment of high daily activity energy cycling would have been required for survival 6. Thus, our genes and metabolic pathways would be optimized under said conditions.
In fact, our living built environments make it difficult to avoid a sedentary lifestyle. The drive for spontaneous activity is important for healthy aging. To wit, obese humans are less active and have greater volumes of sedentary behavior than normal weight humans suggesting that reduced activity may be causative for obesity Epidemiological evidence suggests that excessive sedentary behavior increases risk for obesity Avoidance of overfeeding-induced weight gain in humans is correlated with greater physical activity [also defined as non-exercise activity thermogenesis NEAT ] Rats who display resistance to dietary induced obesity partially accomplish this through enhanced spontaneous physical activity levels movement within cages Thus, the central regulatory factors that dictate volume of sedentary behavior and physical activity have profound importance.
Moreover, we should also examine if signals from peripheral tissues impact central control of voluntary movement as has been suggested by previous studies Therefore, we concluded that studies by basic scientists are needed to determine the molecular and physiological mechanisms underlying central and peripheral control of physical activity and how are these impacted by energy balance.
Rationale As it currently stands, researchers have concluded that sedentary behavior is distinct or independent from time spent in light, moderate, or vigorous intensity physical activity It is not clear how the spectrum of movement from sleep through bed rest, sitting, standing, low level physical activity to moderate and vigorous physical activity differ physiologically.
Thus, sedentary behavior should not be studied in isolation but rather in addition to the effects of low, moderate, and vigorous physical activity.
It will be challenging but important to attempt to separate the physiological impact of increased sitting time from those of standing while performing light activity. We propose that future physiological research endeavors recognize that both sedentary behavior and physical inactivity play a role in disease development.
Recommendation 5 Appropriate models or strategies are needed in both animal models and human subjects to study the links between sedentary behavior and the development of disease. Rationale 7 One of the major challenges in studying the links between sedentary behavior and disease is the time course at which pathologies occur.
Imposing bed rest or transitioning a highly active individual to a period of low activity will quickly lead to a change in function.
Perfect examples are the reduced insulin sensitivity that occurs within hours after there is a transition to sedentary pursuits 15 , and a decrease in skeletal muscle myofibrillar protein synthesis rates following the first 5 hours of unloading This matching of reduced substrate uptake with reduced energy demand is a physiological and not a pathological alteration. If the sedentary behavior continues over a prolonged period current evidence suggests it could transition to a pathological condition that leads to disease 8 , but the time course over which this occurs is unknown.
Moreover, because chronic diseases can take years to develop it will be extremely difficult to mechanistically link a transition of reduced activity to actual chronic disease risk. This is further complicated by the fact that chronic diseases are polygenetic and are the result of interactions of various tissues. Given the large volume of biomedical research studying development of chronic diseases, a very small proportion has examined the physiological role of sedentary behavior as a cause of disease 24 , We are confident that new, unique and pertinent animal and human models can be developed to mechanistically link sedentary behavior to disease development.
This will justify the monitoring and subsequent development of countermeasures for sedentary behavior. This also may provide therapeutic targets for those who are bound to a sedentary life due to disabilities.
Studies are particularly needed that determine the molecular mechanisms by which sedentary behavior accelerates aging processes e. Studies to examine the central and peripheral regulatory features that control daily sedentary behavior also are needed.

For example, the autonomic response, which has sent out the fight-or-flight response, would be aided by the release of such chemicals like epinephrine and norepinephrine , both secreted by the adrenal gland,  in order to further increase blood flow to aid in muscular rejuvenation of oxygen and nutrients.
Oxytocin acts to over-sensitize the limbic system to emotional responses leading to even larger emotional responses.
It acts as an anxiety suppressant mainly found in stressful and social situations. It provides a calming effect to the body during these high stress situations.
Oxytocin is also seen as a strong hormone in maternal attachment and aggression found in new mothers. This hormone also plays a slight part in the female desire to pair and mate.
ACTH is secreted by the posterior pituitary in response to fear and plays a role in the facilitation or inhibition of behaviors and actions to follow. In most cases, a high ACTH secretion will lead to the inhibition of actions that would produce the same fearful response that just occurred. Both are monoamine neurotransmitters that act on different sites in the body. Serotonin acts on receptors in the gastrointestinal tract while dopamine acts on receptors in the brain, while both performing similar functions.
Serotonin has less known on how it carries out its function in reducing depression , but only that it works.
