Associations of aerobic and strength exercise with clinical laboratory test values

<div><p>Objectives</p><p>Physical exercise may affect levels of blood-based biomarkers. However, exercise status is seldom considered in the interpretation of laboratory results. This study reports the associations between habitual exercise participation and clinical laboratory test results.</p><p>Methods</p><p>The effects of days per week of aerobic and strength exercise participation on laboratory test results for 26 biomarkers in young adults aged 18 to 34 years (n = 80,111) were evaluated using percentile distribution analyses and multivariate regression.</p><p>Results</p><p>In both men and women, more days per week of either aerobic or strength exercise were significantly associated with lower levels of glucose, hemoglobin A1c, LDL cholesterol, total cholesterol, triglycerides, estimated glomerular filtration rate, globulin, and C-reactive protein, and significantly higher levels of HDL cholesterol, creatinine, iron, and percent saturation (all p < .05). Type of exercise or gender influenced the observed relationships with exercise frequency for total cholesterol, aspartate aminotransferase, gamma-glutamyl transferase, alkaline phosphatase, uric acid, bilirubin, and iron binding capacity.</p><p>Conclusions</p><p>Physical exercise shifted the distribution of results into the direction suggestive of better health. Reported relationships may help clinicians and patients to better understand and interpret laboratory results in athletic populations and possibly re-evaluate interpretation of reference intervals for physically active populations.</p></div

L'épreuve de l'arc : Les Travaux d'Ulysse

Gravureà l'eau-forte. Planche 39Il s'agit de l'épisode où Pénélope, inspirée par Athéna, défie les prétendants de bander l'arc d'Ulysse. Celui qui réussirait aurait alors droit de l'épouser. On voit Ulysse en train de manier l'arc, dont la flèche doit passer par les douze trous de haches. Primatice et Van Thulden ne suivent pas ici le texte d'Homère : ils représentent des tiges avec des anneaux de tapisserie qui font référence à la fidélité de Pénélope et à sa toile. Derrière Ulysse se trouve Athéna, reconnaissable à son casque et à son bouclier. Les prétendants sont attablés et regardent Ulysse tirer. Télémaque est sans doute le personnage représenté à gauche, l'épée dépassant de sa tunique. Au dernier plan, Pénélope regagne sa chambre avec ses suivantes, obéissant aux injonctions de son fils.téléchargeabl
