Difficulties in Determining the Dose-Response Nature of Competitive Soccer Matches

The monitoring of training loads within soccer is now common practice. Training sessions are monitored to evaluate the physical stimulus imposed upon players to ascertain whether the goals of training sessions have been met. An understanding of the demands of training is also required to facilitate the effective planning and timing of subsequent training sessions. Technological advances in the measurement of physical activity - such as GPS and heart rate monitors - enable sport scientists to accurately gauge the actual work performed by their players (i.e., distances covered) and the physiological response to this work (i.e., heart rates).

The Use of Performance Tests for the Physiological Monitoring of Training in Combat Sports: A Case Study of a World Ranked Mixed Martial Arts Fighter

The sport of mixed martial arts (MMA) is a full contact sport that has had a rapid rise in popularity and participation in recent years. Although initial attempts were made to ban MMA competitions by the medical community and politicians, changes in rules and increased fighter safety and an increased acceptance of this style of combat sport  has seen its popularity outstrip more conventional combat sports such as pro wrestling and boxing. Participation in martial arts is seen as an important form of exercise providing individuals with physical well-being as well as a sense of psychological well-being.

A Multi-Ingredient Nutritional Supplement (MINS) Increases Fat Oxidation and Augments Metabolic Rate

The study investigated the impact of a multi-ingredient nutritional supplement (MINS) on resting metabolic rate and energy expenditure. The supplement contained a combination of factors that are normally administered in isolation (32 g protein, 8.4 g CHO, 1.7 g fibre, 105 mg caffeine and 21 mg green tea extract with 10.5 mg catechins, per 50 g serving. 18 subjects participated in the study (10 males, 8 females), mean age 21.8 yrs. Following overnight fasting, subjects ingested either MINS or an isocaloric maltodextrin placebo.

Is it Yet Time to Throw Away the Old Recipe Book and Consider High Intensity Intermittent Exercise in Clinical Populations?

The first epidemiological exercise studies in the 1950’s established a cause-effect relationship between levels of physical inactivity and cardiovascular disease. In the interim other longitudinal, crosssectional, retrospective and prospective analyses have confirmed that physical activity is cardio-protective and also an inverse relationship exists between mortality rates and leisure time physical activity intensity.

Lance Armstrong’s Era of Performance - Part I: Are his Time Trial Performances Much Different from Other Winners?

The synthetic glycoprotein hormone erythropoietin - best known as recombinant human erythropoietin (rHu–EPO) or epo - became widespread in endurance sports such as professional cycling in the beginning of the 1990s. In 2000, the World Anti–Doping Agency (WADA) implemented a test for epo, after which cyclists are said to have resorted to blood doping as an alternative for epo to boost their performances.
