Enhanced Endurance Performance by Periodization of CHO Intake: "sleep low" strategy [PDF]

, 2016
Purpose: We investigated the effect of a chronic dietary periodization strategy on endurance performance in trained athletes. Methods: 21 triathletes (V[Combining Dot Above]O2max: 58.7 +/- 5.7 mL[middle dot]min-1[middle dot]kg-1) were divided into 2 ...

Optimal neuromuscular performance requires motor neuron phosphagen kinases

The Journal of Physiology, EarlyView.
Abstract figure legend Motor neuron (MN) terminals in fruit flies, mice and humans contain phosphagen kinases, a key enzyme in their energy storage and buffering system. Here we knocked down the primary phosphagen kinase in fruit fly larvae (arginine kinase 1 (ArgK1)) but were surprised to find that MN endurance was unaffected.

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Effects of oral creatine supplementation on high intensity, intermittent exercise performance in competitive squash players [PDF]

, 2001
The purpose of this study was to determine the effects of oral creatine supplementation on high intensity, intermittent exercise performance in competitive squash players. Nine squash players (mean ± SEM V˙O2max = 61.9 ± 2.1ml · kg-1 · min-1; body mass =

Mitochondrial Transporter ABCB10 Protects Against Doxorubicin‐Induced Respiratory Muscle Dysfunction Independent of Changes to Diaphragm Accumulation

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 1, February 2026.
ABSTRACT Background Doxorubicin (DOX) is a highly effective chemotherapeutic agent whose use can cause respiratory toxicity, increasing patient fatigue and negatively impacting quality of life and survival. These adverse effects occur due to diaphragm muscle mitochondrial accumulation of DOX, where it causes reactive oxygen species production and iron ...

Comparative Responses of Self‐Regulated Exercise, Thermoregulation, and Neuromuscular Function to Monophasic Oral Contraceptives Across One Menstrual Cycle

European Journal of Sport Science, Volume 26, Issue 1, January 2026.
ABSTRACT This study investigated the effect of monophasic oral contraceptive (OC) use on self‐paced cycling performance, thermoregulation, and skeletal muscle strength and contractile properties in healthy women. Eight physically active women performed 30 min fixed intensity cycling at 50% Wmax, followed by a 30 min self‐paced time trial (TT) with each
