Strenuous Exercise Worse Than Sedentarism?

Antioxidant supplements in exercise: worse than useless?

TO THE EDITOR: In a recent paper by Higashida et al. (5), the authors report that very large doses of antioxidant vitamins do not prevent the exercise-induced adaptive responses of muscle mitochondria, GLUT4, and insulin action to exercise. As clearly stated in the paper, their data disagree with those reported by three independent research groups from Germany (14), Australia (17), and Spain (4...

Meralgia paresthetica after strenuous exercise.

We present three patients with signs and symptoms of meralgia paresthetica (MP) after long-distance walking and cycling. No other possible causes of MP, such as trauma or exogenous compression, were present. A neuropathy of the lateral femoral cutaneous nerve was confirmed in all patients with somatosensory evoked potentials. We propose that conduction block due to local ischemia during repetit...

Radioelectrocardiographic Changes during Strenuous Exercise

T HE TYPE AND AMOUNT of exercise recommended for the electrocardiographic diagnosis of coronary artery disease have been a matter of discussion and some controversy.' The electrocardiogram has also been studied after extreme effort, such as long-distance running,2 skiing,3 rowing,4 strenuous marching,5 and other forms of sports.6 7 Master and Oppenheimer in 19298 described a standardized two-st...

Quinidine. Worse than adverse?

Influence of strenuous exercise on albumin excretion.

Renal albumin excretion rate was 7.3 mg/24 h (SEM 0.5, range 0.6-21.0) in 66 healthy subjects. This rate increased markedly during and shortly after strenuous exercise on a bicycle ergometer (before: 5.5 +/- 0.6 micrograms/min; during and just after: 16.9 +/- 2.2 micrograms/min; P less than 0.001; n = 30). However, albumin excretion/24 h was not significantly higher during 24 h with a period of...
