Did you Resolve to Exercise More? Read This!

Many of us would benefit from more exercise.  Many of us have made New Year’s resolutions to exercise more.  And many of us will ultimately fail to keep these resolutions.

Science is trying to help.  Researchers are looking at several areas, including:

  1. Can we make exercise more enjoyable? Exercise can be painful and tiring.  If the act of exercising was enjoyable or even pleasurable, would you do it more?
  2. Can we make exercise more productive? If you could enhance your health benefits from working out, would that help you keep your resolution?

Scientists use Agilent technologies and solutions in this research.

UK researchers studied high-endurance exercise training.  They wanted to know if you can enhance your production of muscle mitochondria by reducing carbohydrates.  Mitochondria are the “power generators” in your cells.  They convert oxygen and nutrients into the chemical energy that enables your cells’ activities.  For instance, they enable your muscles to contract.

The researchers studied eight active males before and after performing high-intensity interval running, with either high or low carbohydrate availability.  They found that low carbohydrate availability enhances the production of p53, a gene associated with mitochondrial biogenesis in human skeletal muscle.  This gene may also be related to cancer, aging and insulin resistance.

The researchers used Agilent qPCR reagents to analyze muscle content.

In a separate study, UK researchers examined the relationship between exercise and tyrosine.  Tyrosine is an amino acid found in dairy products, meats, fish, nuts and other foods.  Some people take tyrosine as a supplement.

Previous research has shown that as your environmental temperature increases, your exercise performance decreases.  In this study, scientists tested whether tyrosine can enhance your ability to perform prolonged exercise in a warm environment.  Sadly, the results found that ingesting tyrosine did not influence time to exhaustion or cognitive function during exercise.

The researchers used an Agilent HPLC and column for amino acid analysis.

Overall, some interesting food for thought.  (Hmm… maybe I shouldn’t have said “food” …)
