Disease relevance of Exertion

• OBJECTIVES: We analyzed the possible relation between the presence of a hospital admission delay (> or =24 h), undue physical effort or recurrence of anginal pain, alone or in combination, with the development of free wall rupture (FWR), septal rupture (SR) or papillary muscle rupture (PMR) in patients with an acute myocardial infarction (AMI) [1].
• It is concluded that the daily physical effort of a normal job, significantly increases the serum myoglobin levels in patients with Steinert's disease [2].
• Quantitative effect of theophylline anhydrous on exercise-induced asthma after maximal physical effort [3].

High impact information on Exertion

• Physical effort approximately doubled the plasma levels of adrenaline and noradrenaline in patients as well as in controls [4].
• OBJECTIVES: This study investigated the involvement of serotonin and dopamine in two cost-benefit paradigms, one in which the cost was delay and the other in which it was physical effort [5].
• Our results showed a hormonal response to competition, which was especially characterized by an anticipatory rise of T and C. Depending on outcome, significant higher C levels were found in winners in comparison to losers through all the competition but not in T or PRL, both groups expending a similar physical effort [6].
• Efficient utilization of fatty acids to sustain prolonged physical efforts is thought to be dependent on the carnitine shuttle of muscle [7].
• Pilocarpine produced only little sweating, and external heat and physical effort were associated with elevation of body temperature [8].

Biological context of Exertion

• Prior to medication and during metoprolol treatment, exercise led to an increase in the peripheral platelet count, whereas timolol was associated with a reduction of platelets during physical effort [9].

Anatomical context of Exertion

• The results of this study suggest that entacapone does not change the work capacity, work efficiency or respiratory muscle strength in l-dopa treated PD patients with mild to moderate disease severity, and that its use with l-dopa seems to be safe in conditions of maximal physical effort [10].
• Preliminary study of the relationship between plasma and erythrocyte magnesium variations and some circulating pro-oxidant and antioxidant indices in a standardized physical effort [11].

Associations of Exertion with chemical compounds

• The second experiment examined the effects of O2 on food-deprived rats performing a response (nose poking) that required minimal physical effort to produce deliveries of food pellets [12].
• In a temperature-gradient test paradigm (requiring less physical effort on the part of the subjects) alpha-flupenthixol did not alter the animals' preferred environmental temperature, nor did it disrupt behavioral thermoregulatory ability [13].
• The effect of thyroxine treatment on the liver glycogen content both at rest and following physical effort was also studied [14].
• ACE inhibitor administration does not modify the physical performance of nonathletic subjects; AII is significantly increased with exercise despite captopril treatment; ACE inhibitor decreases GFR significantly but does not influence MA with prolonged physical effort [15].
• The absence of nandrolone metabolites in sedentary subjects supports the hypothesis that the presence of 19-NA and 19-NE could be linked to physical effort even though the origin is not yet clear [16].

Gene context of Exertion

• Furthermore, high production of IFN and TNF may be associated with extensive physical effort [17].
• Changes in SHBG concentrations indicated that they were dependent on the conditions of the physical effort and could be related not only to the concentrations of androgens but also to the reduction in body mass [18].
• We devised a self-administered daily log (the NIH Activity Record, ACTRE), for persons with rheumatoid arthritis (RA), which recorded specific daily activities over a 24-hour period and identified the level of physical effort for each task [19].
• Beta2 power was reduced after physical effort, which may reflect a decrease in active cognitive processing [20].
• Work capacity during exercise is positively influenced by preload increase in ATE, while increased afterload due to isometric training in ATS determines higher systemic resistance during physical effort [21].
