Cardiorespiratory fitness

• WESTLAKE VILLAGE, Calif., Oct. 13, 2023 /PRNewswire-PRWeb/ -- Dr. Jim Stoppani, renowned fitness expert and founder of JYM Supplement Science, is excited to announce the latest addition to his product line: JYM Hydration.
• JYM Hydration is designed to provide athletes and fitness enthusiasts with a superior hydration solution that supports their performance goals.
• Key Features of JYM Hydration include:
  Scientifically Formulated: JYM Hydration is backed by the same rigorous scientific research that has made JYM Supplement Science a trusted name in the industry.
• No Proprietary Blends: Like all JYM Supplement Science products, JYM Hydration features full transparency when it comes to ingredient labeling.

• However, we often sleep less than we need.
• Needing less sleep is a consequence of our ancestors’ choices to remain awake longer — a behaviour that led to evolutionary benefits.

Less sleep needed: An ancestral gift

• Humans are outliers, however, needing sleep for only seven hours, far less than the predicted 9.55 hours of sleep for a primate with similar traits to ours.
• This ancestral choice to sleep less was worthwhile (although some speculate that it may also have had drawbacks).

Less sleep available: A modern misery

• We forgo sleep to pull an all-nighter in preparation for an exam or a meeting, binge-watch TV shows, conform to the sleeplessness trend of the modern culture or scroll through social media.
• Sleep is not a luxury for people who must face sleep disorders, socioeconomic sleep disparity, new parenthood or work obligations of pilots, health-care workers and others with irregular hours.
• Today it is the lack of sleep that is costly because sleep is essential.
• Sleep research pioneer Allan Rechtschaffen noted, “If sleep doesn’t serve an absolutely vital function, it is the biggest mistake the evolutionary process has ever made.”

Countermeasures against sleep deprivation

• Today, getting even an hour or two of extra sleep is challenging.
• But until policies change, how can we better cope with sleep loss?

Protective power of fitness

• Fitness was measured as the ability of the participants’ heart and lungs to supply oxygen and their muscles’ ability to use it while exercising.
• This is referred to as cardiorespiratory fitness, as opposed to muscular fitness.
• A higher VO₂peak indicates better fitness.
• Research has shown that people with higher cardiorespiratory fitness tend to have better brain connectivity and cognition.

Exercise caution

• Other healthy habits of fitter participants such as good sleep hygiene, higher cognitive reserve and healthy diet may have contributed to their better memory performance despite sleep loss.
• However, animal research has shown that aerobic exercise training — which increases cardiorespiratory fitness — can protect against the detriments of sleep deprivation.

• This algorithm is the result of 20 years of breakthrough R&D in the field of advanced heart rate kinetics.
• The apps are also designed for corporate or institutional users and could potentially replace traditional maximum effort cardiovascular exercise testing.
• Driftline (Reykjavik, Iceland) has developed the world's first algorithm for the accurate and simple quantification of human endurance.

• Through the MOVING FORWARD WITH COVID-19 KINESIOLOGY GUIDELINES FOR MAINTAINING OPTIMAL HEALTH, CKA demonstrates how Kinesiologists are part of the solution to support Canadians on the road to recovery.
• The Guidelines focus on six fields of practice where the expertise of Kinesiologists can help: cardiorespiratory health, cognitive capacities including mental health, ergonomics, functional abilities, weight gain and obesity, and safe return to sport.
• Shortness of breath, chest pain, trouble breathing, feeling dizzy or frequent coughing can all be signs of potential heart and respiratory problems.
• In Canada, heart disease is the second leading cause of death after cancer, and a leading cause of hospitalization.
