Palm Cooling and Heating Delays Fatigue During Resistance Exercise in Women.

We previously reported that cold application to the palms between sets of high-intensity bench press exercise produces an ergogenic effect in men. In this study, we hypothesized that palm cooling (PC) or heating during rest intervals between high-intensity weight training sets will increase total repetitions and exercise volume load (kilograms) in resistance trained female subjects in a thermoneutral (TN) environment. Eight female subjects (mean ± SD, age = 25 ± 6 years, height = 160 ± 6 cm, body mass = 56 ± 7 kg, 1-repetition maximum [1RM] = 52 ± 6 kg, weight training experience = 6 ± 2 years) completed 4 sets of 85% 1RM bench press exercise to failure, with 3-minute rest intervals.

Preliminary results: Effect of whole-body cooling in patients with myasthenia gravis.

Introduction: Local muscle cooling has been shown to reduce symptoms in some neuromuscular diseases.

Purpose: To determine whether lowering body temperature using a cooling vest would result in improvement in muscle strength, subjective perceptions of weakness and fatigue, and pulmonary function in patients with generalized myasthenia gravis (MG).

Methods: Patients (five female, one male) with generalized MG, aged 29-58 yr, were studied when mean body temperature was lowered (34.
