As mentioned earlier, aerobic exercise is primarily characterized by activities that cause the heart to pump at an accelerated pace for an extended period of time. In addition to referring to activities that engages the heart, aerobic exercise refers to physical exercise that either improves or involves the body's oxygen consumption. When cardio exercise is used alongside a healthy diet and anaerobic exercise, it can contribute to a healthy life. Cardio is a particularly good category of exercise to perform in order to shed pounds, as cardio exercise burns fat as a fuel source. Fats, along with oxygen and carbohydrates, together form the fuel source used by all cells: adenosine triphosphate (ATP). For some aerobic exercise routines to get you started, check out this great list and this informative page.

The link between physical health and exercise (or lack of it) was further established in 1949 and reported in 1953 by a team led by Jerry Morris.[147][148] Dr. Morris noted that men of similar social class and occupation (bus conductors versus bus drivers) had markedly different rates of heart attacks, depending on the level of exercise they got: bus drivers had a sedentary occupation and a higher incidence of heart disease, while bus conductors were forced to move continually and had a lower incidence of heart disease.[148]
To get your lower abdominals and obliques in pique shape, Fraggos says you can achieve that in just 30 seconds with a “Balancing Tabletop hold with Torso Twists.” To start, she says to hold your legs up in tabletop position in front of the body. Keep your thighs together and arms held bent in front of the chest. Try to maintain balance position as torso twists side to side. Try to keep legs still and only move torso.” Keep your focus; and brush up on these 22 Truths About Willpower if you need help making the most of your 30 seconds.

The hypothalamus is under the control of several “higher” brain centres and several neurotransmitters 13 known to play a major role in various neuroendocrine and behavioural functions, for example, activation of the HPA axis, feeding and locomotion.14 Therefore, the typical HPA axisrelated hormones cortisol, adrenocorticotrophic hormone (ACTH), prolactin (PRL) and human growth hormone (GH) were targeted in the present study.
Aerobic exercise also helps relax blood vessel walls, lower blood pressure, burn body fat, lower blood sugar levels, reduce inflammation, boost mood, and raise "good" HDL cholesterol. Combined with weight loss, it can lower "bad" LDL cholesterol levels, too. Over the long term, aerobic exercise reduces your risk of heart disease, stroke, type 2 diabetes, breast and colon cancer, depression, and falls.

Chronic stress and the subsequent chronic peripheral glucocorticoid secretion plays an important role in the desensitisation of higher brain centre response during acute stressors because it has been shown that in acute (and also chronic) immobilisation, the responsiveness of hypothalamic corticotrophin-releasing hormone (CRH) neurons rapidly falls.26 These adaptation mechanisms could be the consequence of changes in neurotransmitter release, depletion of CRH and/or desensitisation of hypothalamic hormonal release to afferent neurotransmitter input.26 Indeed, concentrations of CRH are elevated, the number of CRH-secreting neurons in the limbic brain regions is increased and the number of CRH binding sites in the frontal cortex is reduced secondary to increased CRH concentrations following chronic stress.25
Recruiting lasted 6 months starting from September 2013. Participants were recruited by means of family doctors to whom the goal of the study was explained. The recruitment flow chart is shown in Figure 1. Three hundred and fifty people aged ≥ 65 were invited to participate. Of these, 51.4% agreed to be included in the screening list while 48.6% refused to participate, mainly for family reasons such as illness/hospitalization/old age of a family member. Forty people were found eligible to participate in the research protocol. Randomly, twenty were assigned to VE and twenty to the control group. The latter were instructed not to take part in any physical activity throughout the study period. All the selected participants signed an informed consent. The study was performed according to the Declaration of Helsinki and approved by the local ethics committee on September 23, 2013.
