“…Another limitation is that we only studied one type of mental stress and one type of physical stress and the combination of the two. Other types of mental and physical stress may combine differently, as indicated by the literature above (23,36).…”

“…For example, Rousselle et al (27) studied responses to mental arithmetic and seated cycling at 50 W and found that combined physical and mental stresses exert a synergistic impact on cardiac output. Also, Myrtek and Spital (23) and Siconolfi et al (36) reported that the combination of physical and mental stress elicits greater cardiovascular responses than either physical or mental stress alone. Myrtek and Spital (23) employed nonvocal mental arithmetic and supine cycling at 25 W as stresses.…”

Physiological responses to mental tasks and physical exercise were studied independently and combined. We hypothesized that combined mental and physical stresses produce a synergistic interaction. We studied cardiovascular responses to 5 min of static handgrip, mental arithmetic, and the combined stimuli in random order in 12 healthy subjects. Muscle sympathetic nerve activity (SNA) and mean arterial blood pressure (MAP) responses to handgrip and the combined stimuli exceeded responses to mental arithmetic, yet no significant difference existed between responses to handgrip and the combined stimuli. Peak changes in SNA (in %) were greatest during handgrip (188 ± 41), followed by the combined stimuli (166 ± 31) and mental arithmetic (51 ± 9). Peak changes in MAP (in mmHg) were also greatest during handgrip (26 ± 4), followed by the combined stimuli (23 ± 3) and then mental arithmetic (8 ± 2). Peak changes in heart rate (in beats/min) followed the same trend: handgrip (15 ± 2), combined (13 ± 2), and mental arithmetic (10 ± 2). Mental stimulation did not synergistically interact with or add to the responses elicited by handgrip exercise; in fact, a trend existed for math during handgrip to reduce responses relative to handgrip alone.

“…The results indicate that mental stress alone causes increased heart rate, and the combination of exercise and mental stress produces an additional effect on this same variable. Siconolfi et al 36 found similar results in patients with coronary heart disease. These studies suggest that ventilatory variables are less sensitive than heart rate to the conditions of physical and mental stress.…”

Precise measurement of sedentary behavior and physical activity is necessary to characterize the dose-response relationship between these variables and health outcomes. The most frequently used methods employ portable devices to measure mechanical or physiological parameters (eg, pedometers, heart rate monitors, accelerometers). There is considerable variability in the accuracy of total energy expenditure (TEE) estimates from these devices. This review examines the potential of measurement of ventilation (VE) to provide an estimate of free-living TEE. The existence of a linear relationship between VE and energy expenditure (EE) was demonstrated in the mid-20th century. However, few studies have investigated this parameter as an estimate of EE due to the cumbersome equipment required to measure VE. Portable systems that measure VE without the use of a mouthpiece have existed for about 20 years (respiratory inductive plethysmography). However, these devices are adapted for clinical monitoring and are too cumbersome to be used in conditions of daily life. Technological innovations of recent years (small electromagnetic coils glued on the chest/back) suggest that VE could be estimated from variations in rib cage and abdominal distances. This method of TEE estimation is based on the development of individual/group calibration curves to predict the relationship between ventilation and oxygen consumption. The new method provides a reasonably accurate estimate of TEE in different free-living conditions such as sitting, standing, and walking. Further work is required to integrate these electromagnetic coils into a jacket or T-shirt to create a wearable device suitable for long-term use in free-living conditions.

Mitral valve prolapse (MYP) is frequently associated with multiple symptoms such as anxiety, palpitations and chest pain that may be related to an imbalance of autonomic tone. In this study, 10 asymptomatic subjects with and 11 subjects without MYP shown by echocardiography underwent the Stroop mental stress test. The resting heart rate of 68 ± 16/min increased to 76 ± 19/min in subjects without MVP during mental stress (p < 0.05), while in subjects with MVP the resting heart rate increased from 76 ± 14/min to 82 ± 13/min (p < 0.05). Resting systolic blood pressure of 109 ± 13 mm Hg in subjects without MVP increased to 122 ± 13 mm Hg during mental stress (p < 0.05). Subjects with MVP had a resting systolic blood pressure of 121 ± 12 mm Hg which increased to 137 ± 13 mm Hg (p < 0.05). The resting diastolic blood pressure of 69 ± 9 mm Hg increased to 76 ± 11 mm Hg (p < 0.05) in subjects with MVP during mental stress. Subjects with MVP increased the resting diastolic blood pressure to 89 ± 8 mm Hg from a resting level of 79 ± 8 mm Hg (p < 0.05). Subjects with MVP had significantly higher heart rates, systolic and diastolic blood pressure than the normal subjects before, during and after mental stress. The magnitude of these increases was similar in both groups. Epinephrine and norepinephrine levels in venous blood before, immediately after mental stress and 1,5, and 10 min after mental stress did not change significantly in either group. The data suggest a different autonomic tone in subjects with MVP without differences in the level of circulating catecholamines. This may reflect a difference in ß-receptors or parasympathetic activity in subjects with MVP.
