Video Abstract for the ESSR 46.2 article “Potential Role of MicroRNA in the Anabolic Capacity of Skeletal Muscle With Aging” from author Donato Rivas. Age-induced loss of skeletal muscle mass and function, termed sarcopenia, may be the result of diminished response to anabolic stimulation. This review will explore the hypothesis that alterations in the expression of microRNA with aging contributes to reduced muscle plasticity resulting in impaired skeletal muscle adaptations to exercise-induced anabolic stimulation.
To qualify for inclusion, studies had to be level 1 or level 2 (randomized controlled trials); had to compare rehabilitation interventions, such as exercise or manual therapy, with other treatments or placebo; had to include validated outcome measures of pain, function, or disability; and had to be limited to individuals with diagnosed impingement syndrome. Impingement syndrome was determined by a positive impingement sign per Neer or Hawkins criteria, or both. Articles were excluded if they addressed other shoulder conditions (eg, calcific tendinosis, full-thickness rotator cuff tears, adhesive capsulitis, osteoarthritis), addressed postoperative management, were retrospective studies or case series, or used other outcome measures.
When performed at high intensity until exhaustion, OLDE has been shown to induce both peripheral and central fatigue [11, 17, 18]. However, as the exercise performed in these studies did not take place on the same ergometer where neuromuscular function was tested, the extent of peripheral and central fatigue remained unclear. To avoid the need to transfer the participant from the exercising ergometer to the dynamometer (to assess muscle fatigue), we recently developed in our laboratory a OLDE protocol on a dynamometer, reducing the time delay between cessation of the exercise and start of neuromuscular testing [8]. In this study, we demonstrated that both peripheral and central fatigue significantly recovered between exhaustion and after three minutes, but also that high intensity OLDE alters cortical and spinal excitability. Previous studies [8, 11, 17, 18] describing muscle fatigue induced by high intensity OLDE focused only on isometric muscle fatigue (i.e. muscle fatigue measured during isometric contractions) and did not describe the extent of isokinetic muscle fatigue (i.e. muscle fatigue measured during isokinetic contractions) and its recovery. Consequently, an additional aim of this study was to describe the isokinetic muscle fatigue and its recovery induced by high intensity OLDE.
Although there have been hundreds of studies on physical exercise and the immune system, there is little direct evidence on its connection to illness. Epidemiological evidence suggests that moderate exercise has a beneficial effect on the human immune system; an effect which is modeled in a J curve. Moderate exercise has been associated with a 29% decreased incidence of upper respiratory tract infections (URTI), but studies of marathon runners found that their prolonged high-intensity exercise was associated with an increased risk of infection occurrence. However, another study did not find the effect. Immune cell functions are impaired following acute sessions of prolonged, high-intensity exercise, and some studies have found that athletes are at a higher risk for infections. Studies have shown that strenuous stress for long durations, such as training for a marathon, can suppress the immune system by decreasing the concentration of lymphocytes.[26] The immune systems of athletes and nonathletes are generally similar. Athletes may have slightly elevated natural killer cell count and cytolytic action, but these are unlikely to be clinically significant.[27]
What sets Pilates apart is its focus on toning the muscles with springs, bands, or your own body weight. Alycea Ungaro, author of 15 Minute Everyday Pilates, shares her routine for beginners. Some moves are shown using Pilates studio equipment, but you can do most moves at home. Check with a doctor first if you're a man over age 45 or a woman over age 55, or if you have a medical condition.
Resistance bands serve as another space and equipment saver. These elastic bands typically have handles on the end, and you can perform a variety of exercises with them. If you'd like to increase the intensity and resistance, you can use two bands at once. Surgical tubing makes and extremely inexpensive resistance band, provided you create a safe way to hold onto the ends so that you don't accidentally let go.
However, our goal is not necessarily to move more weight but to safely and efficiently target your muscles. By dramatically slowing the speed of the movements and ensuring that the weight smoothly changes directions, we virtually eliminate the possibility of injury. Excessive momentum is removed so only the muscles (and not the joints, tendons, or ligaments) are taxed.
If the phrase "exercise videos" calls to mind Buns of Steel, purple spandex, and leg warmers, you'll be pleasantly surprised. The fitness video industry has come a long way. These days you can find anything from and dance programs to Pilates and yoga on DVD. In fact, there are so many out there that finding the best exercise videos can be a daunting proposition.
(3) Recovery Phase (<60% HRR). Postural control and spine mobility exercises in a quadrupedal position with the platform support, exercises of static balance over either 4 or 2 supports, eyes either open or closed, and with core muscle activation. The latter phase also included various poststretch exercises to restore the preexercise muscle length.
