The influence of citrus aurantium and caffeine complex versus placebo on the cardiac autonomic response: a double blind crossover design.

Background: The purpose of this study was to examine the resting cardiac autonomic nervous system's response to the ingestion of a complex containing Citrus aurantium + Caffeine (CA + C) and its influence on recovery following a high-intensity anaerobic exercise bout in habitual caffeine users.

Methods: Ten physically active males (25.1 ± 3.

Changes in body composition, bone metabolism, strength, and skill-specific performance resulting from 16-weeks of HIFT.

High Intensity Functional Training (HIFT) is a training modality, characterized by multimodal exercises performed at high-intensity. Little is known about the training adaptations that occur as a prolonged training program. The purpose of this study was to examine changes in body composition, bone metabolism, strength, and skill-specific performance over 16-weeks of HIFT.

Autonomic response to a short and long bout of high-intensity functional training.

The evaluation of Autonomic Nervous System (ANS) recovery following exercise provides insight into the transient stress placed on the cardiovascular system. High-Intensity Functional Training (HIFT) is a form of intense exercise that is prescribed in various modalities and durations; however, little is known about the influence of HIFT duration on ANS recovery. Ten apparently healthy males (28.
