Electromyographic response of the abdominal musculature to varying abdominal exercises.

This study examined the electromyographic (EMG) response of the upper rectus abdominis (URA), lower rectus abdominis (LRA), internal obliques (IOs), external obliques (EOs), and the rectus femoris (RF) during various abdominal exercises (crunch, supine V-up, prone V-up on ball, prone V-up on slide board, prone V-up on TRX, and prone V-up on Power Wheel). The subjects (n = 21) performed an isometric contraction of the abdominal musculature while performing these exercises. Testing revealed no statistically significant differences between any of the exercises with respect to the EOs, the URA, or the LRA.

Effects of dehydration and rehydration on the one-repetition maximum bench press of weight-trained males.

Dehydration, a common practice among competitive athletes in sports including weight classes, has uncertain effects on strength. This study examined the effects of passive dehydration (D, approximately 2 hours in a sauna) followed by rehydration (R, approximately 2 hours of rest with water ad libitum) on bench press one-repetition maximum (1RM). Ten weight-trained males (x +/- SE; age = 25 +/- 1 years; mass = 85.

Blood lead levels in emergency department patients with retained lead bullets and shrapnel.

Objective: To determine whether patients with retained lead shrapnel who present to the ED have elevated whole blood lead levels (BLLs) compared with matched control patients.

Methods: Test subjects were patients with x-ray evidence of retained lead shrapnel who presented to any of three urban EDs, and consented to inclusion in the study. BLLs were obtained from 15 ED patients, and data regarding time since injury and symptoms of plumbism were collected.

Thyrotoxic periodic paralysis in a Jamaican male.

Thyrotoxic periodic paralysis is a rare endocrine disorder most prevalent among individuals of Asian descent that presents as proximal muscle weakness, hypokalemia, and signs of hyperthyroidism. We present the case report of a patient with previously undiagnosed hyperthyroidism, protracted muscle weakness with transient exacerbations, and nocturnal onset of periodic paralysis affecting the upper and lower limbs.
