Beetroot juice consumption does not affect cycling performance or economy in recreationally-active females

Beetroot Juice is a commercially-available beverage that, when consumed, increases blood levels of nitrate and nitrite (and most likely nitric oxide) and in turn affects many physiological and metabolic processes.

Fatiguing muscle contractions of a small hand muscle can lead to fatigue of the same and other muscles in the opposite limb

The KT committee is introducing a new format for our Knowledge Translation articles with an emphasis on how current research articles may impact practitioners. Our first article is written by Katie Kowalski, PhD (Candidate) at Western University. Katie graduated as a doctor of Physical Therapy with honours from the University of Wisconsin-Madison and has many years experience working in a healthcare setting.

Research in Nutritional Supplements and Nutraceuticals for Health, Physical Activity and Performance: Moving Forward

Nutritional supplements - a multi-billion-dollar global industry - are heavily marketed to consumers to optimize health, support well-being and improve performance. However, determining whether their purported effects are supported by high quality science can be challenging.

Influenza vaccine response may be influenced by lifestyle factors in highly active young men

A growing body of literature suggests that not only do overweight and obese individuals experience a greater proportion of negative outcomes as a result of influenza exposure but also vaccination response differs across age groups and sex.

Time Course of Recovery is Similar for the Back Squat, Bench Press, and Deadlift in Well-Trained Males

Among various fitness communities it has been long-standing belief that the deadlift exercise causes greater fatigue than the squat or bench press. Therefore, it is commonly said that the deadlift should be trained less frequently than the squat or bench press even though no data actually supports this notion.

Vitamin and mineral supplement use in medically complex, community-living, older adults

Vitamin and mineral supplements have been available for decades. Individuals who take multiple medications and those who are at risk for low nutritional intake from food, may benefit from using these types of supplements.

Nervous system control of heart rate in response to exercise during pregnancy

The nine short months of pregnancy are associated with profound physiological adaptations to the cardiovascular and nervous systems. This includes a 50% increase in blood volume, 30% increase in cardiac output and 20% increase in heart rate at rest.

Aging and Sympathetic Response to Exercise

When activated by stressors such as exercise, sympathetic nerves supplying the heart and muscle blood vessels release a chemical called noradrenaline which causes increases in heart rate and blood vessel constriction.

Longer muscle lengths may offer a protective effect against preceding activity during explosive performance: The long and short of rate of force development

The optimization of explosive performance is important for enhancing athletic performance and for everyday life, such as recovering from a slip, fall or trip. Explosive performance can be quantified by rate of force development, which is how fast force is produced over a given period of time.

Heart rate variability responses to acute and repeated post-exercise sauna in trained cyclists

The use of heat exposure has been a growing area of scientific interest with performance and health benefits reported for adults. Athletes typically undertake exercise in the heat to develop adaptations that lead to improved performance.
