One variable of interest in Paoli and colleagues’ study was excess postexercise oxygen consumption, or EPOC. This represents the oxygen consumption, or energy expenditure (above the baseline, or pre-exercise, level), that occurs after an exercise bout. It is sometimes called “after-burn,” implying the burning of calories after the workout.
Imagine this science fiction scenario: While preparing your client for a set of back squats, the Training Scene Investigators (TSI) interrupt with a spot check. After your client has undergone a DNA mouth swab, a quick noninvasive laser muscle biopsy and a family history interview, the agents issue a comprehensive report.
Exercise professionals devote fervent attention to learning the intricate mechanisms of muscle actions and understanding how the contractile proteins (such as myosin and actin) create force to do an array of exercises. But the source of that force—the biochemistry of energy—often remains a mystery. This column will discuss recent explanations that help demystify the processes happening at the molecular level, where cells channel energy from food into the work accomplished by exercise.
How you breathe affects how you live; it's more than automatic. Breathing techniques and patterns are regularly advocated for relaxation, stress management, control of psychophysiological states and improvement of organ function (Ritz & Roth 2003). Anatomically speaking, there is a favorable equilibrium (balance between inhalation and exhalation pressures) in breathin...
Studies have shown that seated desk work can have negative health and mobility repercussions as we age. A new study suggests that physically demanding jobs can also impact function later in life.
The study included 5,200 public sector employees participating in the Finnish Longitudinal Study on Municipal Employees. The primary purpose of the study was to understand the impact of leisure-time physical activity (LPA) and occupational physical activity (OPA) on mobility limitations among older adults.
According to a study in the Annals of Internal Medicine (2014; 160 , 517–25), close to 21 million adults aged 20 and older had confirmed diabetes in 2010, and some sectors of the population were more likely than others to develop the disease.
Using data from the National Health and Nutrition Examination Surveys, the scientists looked at diabetes rates and diagnosis among adults in 1988–1994 and 1999–2010.*
Over the past several years, kettlebells have emerged (or reemerged) as a prominent fixture in fitness facilities. But are these crude tools worth their pood?*
To learn about the benefits of kettlebells, researchers enlisted by the American Council on Exercise studied 30 participants, who were divided into two groups—an exercise group and a nonexercise control group. Prior to the trials, the exercisers completed two introductory kettlebell sessions to
learn form and technique; they practiced one- and two-handed swings, snatches and other movements.
Did you know that Pilates continues to grow in popularity, and its practice is now familiar to people around the world? Maybe you’ve already experienced the effectiveness of Pilates or are thinking about taking lessons.
Good news! Researchers have proven certain benefits of this form of exercise. Shirley Archer, JD, MA, 2008 IDEA Fitness Instructor of the Year and IDEA’s mind-body-spirit spokesperson, discusses the benefits below.
