A high-fat, low-carbohydrate, ketogenic diet has already appealed to athletes for a long time due to its purported ability to improve exercise performance and post-exercise recovery. The availability of ketone supplements has further sparked such interest. The review therefore focuses on the potential beneficial impact of exogenous and endogenous k...
Purpose
Team sports often involve intermittent sprints. During these activities the Phosphocreatine-ATP buffer (ATP-PCr) signifies the major anaerobic energy substrate. While the effects of ketogenic diets (KD) on carbohydrate and fat metabolism during endurance exercise are widely reported, we explored keto-adaptation in ATP-PCr metabolism during...
Introduction: Natural remedies in the treatment of health conditions are an appealing option for many individuals. Previous studies reported that fermented and unfermented rooibos tea have considerable anti-inflammatory and antioxidative properties. Most of this knowledge, however, originates from animal and cell culture studies. Objectives: The ai...

Introduction: This case study aimed to describe potential changes in neuromuscular activation and synergies after an eight-day cross-country mountainbike (XCM) stage race.
Methods: A peak power output test was performed five days before the race. Two days before the start and after seven days of racing, the athlete performed a power-based Lamberts...
Accurate assessment of resting metabolic rate (RMR) is necessary for calorie-based recommendations in diet and exercise training interventions. BodyMetrix™ is an ultrasound-based device that provides an estimate of RMR based on body composition, but has not been proven valid or reliable. Therefore, we evaluated the agreement between Katch–McArdle p...
INTRODUCTION:
According to the South Africa Demographic and Health Survey, 68% of South African women are obese, based on BMI scores. It is also known that there is a strong association between low socio-economic status and obesity risk (Pireyre et al., 2016). Furthermore, fat oxidation rate during rest and exercise is linked to increased metabolic...
Introduction
Mountain bike performance are influenced by both physiological and skill-based qualities of the riders. Power output lactate threshold have been identified as strong physiological predictor of mountain bike race performance (Ahrend et al., 2016; Gregory et al., 2007). Although various similarities exist within the different cycling eve...
Background:
The study set out to identify physiological variables that may predict performance in The Cape Epic, an 8-day multi-stage mountain bike (MTB) race held annually in South Africa.
Methods:
Twenty four amateur riders underwent VO2max testing within the 8 weeks prior to the event. Blood lactate measurements were taken to determine the po...
This study investigated the effectiveness of rugby-specific video-based perceptual training on the speed and agility of club-level rugby union players. Twenty-six players were randomly divided into either a video-based, field-based or conventional training group. For six weeks, the video-based and field-based groups performed agility training twice...
The aim of this study was to investigate the effects of a heat dissipating compression garment (CG) during a running performance test. Ten male recreational runners (mean ± SD: age 23 ± 3 years; V[Combining Dot Above]O2max 55.8 ± 4.8 ml·kg·min) completed two identical sessions wearing either CG or conventional t-shirt (CON). Each trial included a 4...

Introduction
Mountain biking is one of the most rapid growing sports in the world with the amount of multi-stage mountain bike events increasing each year. A...
Introduction
The effectiveness of wearing CGs during exercise has been questioned in the majority of studies, not finding differences in cardiorespiratory, thermoregulatory or metabolic during submaximal and maximal exercises (1, 2).
Despite previous physiological factors, there is an amount of evidences supporting that the central nervous system...
