1601. Effectiveness Study of Postoperative Rotator Cuff Repair Rehabilitation

Last Update Posted : March 28, 2013 Sponsor: Orthopedic Institute, Sioux Falls, SD Information provided by (Responsible Party): Keith Baumgarten, Orthopedic Institute, Sioux Falls, SD Study Details Study Description Go to Brief Summary: There are very few level 1 or level 2 evidence studies that examine postoperative rehabilitation of rotator cuff repair and shoulder arthroplasty. A systematic review of level 1 or level 2 evidence studies was performed (Baumgarten et al., Sports Health, 2009 (...) ) that found only four studies that examined rotator cuff repair rehabilitation. The current study was performed to determine if there is a significant difference in passive glenohumeral joint range of motion, active glenohumeral joint range of motion, scapular substitution, and subjects measured outcome scores (clinimetrics) in patients who undergo rotator cuff repair when treated postoperatively with pulley exercises compared to Jackins' exercises. Null Hypothesis: There will be no significant difference

1604. Carbohydrate Use During and Following Exercise

Center Information provided by (Responsible Party): Maastricht University Medical Center Study Details Study Description Go to Brief Summary: Carbohydrates are an integral component of sports nutrition. Providing carbohydrate (CHO) during exercise delays the onset of fatigue and improves exercise performance by maintaining high rates of CHO oxidation. Traditionally, glucose, or glucose polymers have been the preferential CHO source found in sports drinks. However, during the intestinal absorption (...) of large amounts of glucose (>1.2 g/min), sodium-dependent glucose transporters (SGLT1) may become fully saturated, potentially limiting the rate of exogenous CHO oxidation. In an effort to evade this limitation, research has suggested using multiple transportable carbohydrates in the composition of sports drinks. Multiple transportable carbohydrates are combinations of simple sugars that use different intestinal transporters during the absorption process. Ingesting multiple transportable carbohydrates

by the National Library of Medicine related topics: Arms and Interventions Go to Arm Intervention/treatment Experimental: COPD Dietary Supplement: Beetroot Other Name: James Whites Drinks beetroot sports shot Dietary Supplement: Beetroot placebo Other Name: James Whites Drinks beetroot sports shot Outcome Measures Go to Primary Outcome Measures : O2 cost of moderate-intensity cycling exercise [ Time Frame: Twice over a maximum of a 2 month period ] whether nitrate reduces the O2 cost of moderate intensity (...) . Recent findings in healthy young people suggest that increasing the amount of nitrate in our diet in the form of beetroot juice can improve the ability to exercise. Studies involving cycling have shown that less oxygen is needed to perform the same level of exercise after taking more nitrate in the diet. Nitrate (found in abundance in beetroot) is known to be converted in the body to nitric oxide (NO), a substance which increases blood flow and may affect the energy-producing mechanisms inside muscle

1608. A proposal for an upper limit of leucine safe intake in healthy adults. Full Text available with Trip Pro

A proposal for an upper limit of leucine safe intake in healthy adults. Based on recent research, an upper limit of safe intake (ULSI) for leucine is proposed for healthy adults: 0.53 g/(kg·d). Because leucine has been used as a dietary supplement for many years in people practicing exercise and sport, further study with long-term exposure to leucine in this specific subpopulation should be performed to eventually adjust the ULSI.

1609. Melatonin administrated immediately before an intense exercise reverses oxidative stress, improves immunological defenses and lipid metabolism in football players. (Abstract)

football players, who were divided into two groups, an experimental group (supplementation with 6 mg of melatonin administered 30 min prior to exercise) and a control group (placebo without melatonin). They performed a continuous exercise of high intensity (135 beats/min). Samples were collected 30 min before the exercise and 3, 15 and 60 min during the exercise. The results indicated that the acute sport training presented: a) increased lipid peroxidation products (MDA) in both groups, control (...) Melatonin administrated immediately before an intense exercise reverses oxidative stress, improves immunological defenses and lipid metabolism in football players. Acute sport exercise leads to a strong stimulation of muscle tissue and a change in the organism energy demands. This study was designed to investigate the effect of oral melatonin supplementation on human physiological functions associated with acute exercise. Immune, endocrine and metabolic parameters were measured in 16 young male

1613. The Wonder Physio… A guest blog by Paul Westwood

put their faith in a variety of therapists to help them with their injuries and sometimes to help them improve performance. But why do they do this, and what do we need to do as therapists in order to help athletes perform at their best? Here are my own thoughts and some experiences of the wonderful world of sports physiotherapy. Thanks to Adam for allowing me the opportunity. I know coaches and athletes who follow Adam’s work, that provides valuable knowledge and advice to help athletes at all (...) had developed an unhealthy obsession with stretching and foam rolling, talk about operant conditioning? Yet he still thought his Wonder Physio was awesome!!! Excuse my bias but hang out with a bunch of elite triathletes for any length of time and you will see a lot of anxiety, insecurity, poor confidence and mal-adaptive behavior. High performance sport creates a lot of pressure. As a physio in elite sport I have found the ‘Going-for-Coffee Rx Technique’ (patent pending) highly successful in fully

1616. The Incredibly Bad Science Behind Dr. Esselstyn’s Plant-based Diet

Be Serious! Whatever oil this might be (?sunflower) is right out even though it comes from a plant. According to Esselstyn, using his brilliant ‘logic and intuition” all fats, whether saturated or unsaturated are going to damage the lining of your arteries. The best randomized controlled trials we have for diet to prevent coronary artery disease (CAD, the cause of heart attacks) have shown that supplementing diet with olive oil and nuts substantially lowers CAD. Every observational study in nutrition has (...) and then compare how the two groups had fared after three years.” If he had followed his original intent, and randomized patients entering the study, he could claim that he had performed a legitimate, important scientific study. Twelve of the 24 would be allocated by lottery to the Esselstyn diet and 12 to whatever was the standard recommended CAD diet at the time. Unfortunately this approach, due to a “lack of funding, was not practical.” So instead, 24 patients were sent to him, “all suffering from advanced

questions I thought were just uniform consequences of aging: 1. Reduction in strength and/or endurance. 2. Loss of height. 3. Deterioration in your ability to play sports. After taking the quiz, I was told that answering yes to 3 of the 10 questions strongly suggests you have low T. In addition, according to the site, if you answered yes to question 1 (decreased libido) or 7 (less strong erections) you have low T. Based on this quiz, I and 99% of men my age must have low T!!

1619. Advise patients to steer clear of these six orthopedic procedures

services listed by this specialty group were particularly "low impact": The American Academy of Orthopaedic Surgeons named use of an over-the-counter supplement [glucosamine and chondroitin] as one of the top practices to question. It similarly listed two small durable-medical-equipment items and a rare, minor procedure (needle lavage for osteoarthritis of the knee). Strikingly, no major procedures — the source of orthopedic surgeons' revenue — appear on the list, though documented wide variation (...) in elective knee replacement and arthroscopy among Medicare beneficiaries suggests that some surgeries might have been appropriate for inclusion. At the Lown Institute's recent , a group of orthopedic surgeons identified five other low-value surgical procedures that, in contrast to the AAOS list, are frequently performed at great expense in the U.S. but provide little or no benefit to patients. 1) Vertebroplasty for spinal compression fractures - in two randomized controlled trials comparing
