The Effect of Rider Weight and Additional Weight in Icelandic Horses in Tölt: Part I. Physiological Responses

This experimental study assessed the physiological impact of increasing rider and tack weight on Icelandic horses performing the tölt gait. Eight trained horses were subjected to incremental body weight ratios (BWR) ranging from 20% to 35%, with physiological markers such as heart rate, plasma lactate, breathing frequency, rectal temperature, and

Hawthorn extract for treating chronic heart failure

This systematic review assessed the effects of hawthorn extract as an adjunctive treatment for chronic heart failure (CHF), analyzing data from 14 randomized, double-blind, placebo-controlled trials involving 855 patients. The findings showed that hawthorn extract significantly improved exercise tolerance, increased maximal workload, reduced the pressure-heart rate product, and alleviated symptoms

Percutaneous coronary intervention in stable angina (ORBITA): a double-blind, randomised controlled trial

The ORBITA trial, a double-blind, randomized controlled study, evaluated the efficacy of percutaneous coronary intervention (PCI) compared to a placebo procedure in 200 patients with stable angina and significant single-vessel stenosis. After six weeks of medication optimization, results showed no significant difference in exercise time improvement between PCI and the

Acute L-arginine supplementation reduces the O2 cost of moderate-intensity exercise and enhances high-intensity exercise tolerance

This randomized controlled trial examined the effects of acute L-arginine supplementation on oxygen consumption during moderate-intensity exercise and high-intensity exercise tolerance. Results showed a 7% reduction in steady-state oxygen uptake (VO₂) during moderate-intensity exercise (P < 0.05) and an increased time to exhaustion during high-intensity exercise (707 ± 232 vs.
