Increased Postexercise Lipoxin A4 Levels in Exhaled Breath Condensate in Asthmatic Children With Exercise-Induced Bronchoconstriction.

Sun, 27 Mar 2016 09:51:02 +0100

CONCLUSIONS: Levels of EBC LXA4 increased immediately after exercise in asthmatic children with a positive exercise challenge response. We hypothesize that airway LXA4 levels increase to compensate bronchoconstriction and suppress acute inflammation, and that spontaneous bronchodilatation after EIB may be due to LXA4.

"Walking with Only Noninvasive Ventilation in Stable Hypercapnic COPD Patients: Sufficient or not?" COPD. 2016 Mar 25;:1 Authors: Walker DJ, Windisch W, Dreher M Abstract We are grateful to Ulasli and Esquinas for their comments to our paper.. They argued that arterial blood gas analyses were not performed without oxygen prior to the 6-minute walk test with noninvasive ventilation (6MWT-NPPV). This point has already been discussed in our original work by indicating the limitations of our study. The reason for using oxygen prior to exercise testing was to guarantee comparable starting conditions.

Epidemiology and Severity of Sports and Recreation Injuries Presenting to a Tertiary Adult Emergency Department.

Sat, 26 Mar 2016 22:28:02 +0100

CONCLUSIONS: The 7.6% admission rate is higher than previously reported, likely because the study institution is a tertiary referral center. ATV riding is associated with higher severity injuries that are more likely to require hospital admission. Most sports injuries that present to an emergency department, specifically isolated soft tissue injuries of the extremities, may be more efficiently treated in a non-emergent setting.

6 Amazing Tips for Staying in Shape While Traveling

Sat, 26 Mar 2016 15:48:58 +0100

Staying fit while on the road (and otherwise) is extremely important and somehow I feel that fitness and travel go hand in hand. If you travel a lot , you tend to stay fit and if you are not fit, traveling is just not as much fun, or important anymore -- after all, health always comes first, right? I would like to think of myself as a fit traveler though I am always striving towards harder fitness goals. Staying focused and motivated is the key. As a traveler, any sort of "regular" gym sessions are impossible , however, if you are focused, you can exercise literally anywhere in the world. You don't need a fancy gym and regular classes to keep yourself in shape. People often ask me how I stay fit (modestly isn't my virtue, as you see) and the answer is simple -- I am always "on the move" ...

Relationship Between Agility Tests and Short Sprints: Reliability and Smallest Worthwhile Difference in National Collegiate Athletic Association Division-I Football Players

Sat, 26 Mar 2016 10:25:17 +0100

Abstract: Mann, JB, Ivey, PA, Mayhew, JL, Schumacher, RM, and Brechue, WF. Relationship between agility tests and short sprints: reliability and smallest worthwhile difference in National Collegiate Athletic Association Division-I football players. J Strength Cond Res 30(4): 893–900, 2016—The Pro-Agility test (I-Test) and 3-cone drill (3-CD) are widely used in football to assess quickness in change of direction. Likewise, the 10-yard (yd) sprint, a test of sprint acceleration, is gaining popularity for testing physical competency in football players. Despite their frequent use, little information exists on the relationship between agility and sprint tests as well the reliability and degree of change necessary to indicate meaningful improvement resulting from training.

Effects of Hypohydration on Repeated 40-yd Sprint Performance

Sat, 26 Mar 2016 10:25:17 +0100

This study examined the effects of hypohydration on repeated 40-yd sprint performance. Anaerobically fit current and former Division II male athletes (n = 12) completed 2 bouts of 10 × 40-yd sprints followed by an agility test, dehydrated (∼3% body weight [DT]), or hydrated trial (HT). Statistical analysis of group means indicated that hypohydration had little effect on sprint times for either the first (DT= 5.38 ± 0.37; HT = 5.35 ± 0.34) or second (DT = 5.47 ± 0.39; HT = 5.42 ± 0.39) bout of 10 sprints with only sprint number 2, 5, and 6 of bout 2 reaching statistical significance. However, when individual sprint performance was considered, a greater effect was seen. In all, 83% (10 of 12) of subjects experienced a meaningful change (≥0.1 seconds) (positive or negative) in mean s...

Abstract: Halperin, I, Williams, KJ, Martin, DT, and Chapman, DW. The effects of attentional focusing instructions on force production during the isometric midthigh pull. J Strength Cond Res 30(4): 919–923, 2016—Verbal instructions play a key role in motor learning and performance. Whereas directing one's attention toward bodily movements or muscles (internal focus) tends to hinder performance, instructing persons to focus on the movement outcome, or an external object related to the performed task (external focus) enhances performance. The study's purpose was to examine whether focus of attention affects maximal force production during an isometric midthigh pull (IMTP) among 18 trained athletes (8F & 10M). Athletes performed 3 IMTP trials a day for 3 consecutive days. The first day wa...

Grading the Functional Movement Screen: A Comparison of Manual (Real-Time) and Objective Methods

Sat, 26 Mar 2016 10:25:17 +0100

This study compared the FMS scores assigned by a certified FMS tester to those measured by an objective inertial-based (IMU) motion capture system. Eleven female division I collegiate athletes performed 6 FMS exercises and were manually graded by a certified tester. Explicit kinematic thresholds were formulated to correspond to each of the grading criteria for each FMS exercise and then used to grade athletes objectively using the IMU data. The levels of agreement between the 2 grading methods were poor in all 6 FMS exercises and implies that manual grading of the FMS may be confounded by vague grading criteria. Evidently, more explicit grading guidelines are needed to improve the uniformity and accuracy of manual FMS grading and also facilitate the use of objective measurement systems in ...

Abstract: McMillian, DJ, Rynders, ZG, and Trudeau, TR. Modifying the functional movement screen deep squat test: the effect of foot and arm positional variations. J Strength Cond Res 30(4): 973–979, 2016—The functional movement screen (FMS) was developed as an evaluation tool for assessing the fundamental movement patterns believed to be prerequisites for functional activity. However, some of the FMS component movements, such as the deep overhead squat test (DST), likely represent novel motor challenges on which poor performance might reflect inexperience with the task rather than a movement impairment. The purpose of this study was to examine the effects of positional variations on DST scores in a population of young, healthy adults. We hypothesized that self-selecting foot positionin...

Sat, 26 Mar 2016 10:25:17 +0100

Abstract: Swain, DP, Kelleran, KJ, Graves, MS, and Morrison, S. Impact forces of walking and running at the same intensity. J Strength Cond Res 30(4): 1042–1049, 2016—Moderate-intensity walking (horizontal, WH), vigorous-intensity walking (incline, WI), and vigorous-intensity running (horizontal, R) were compared. The hypothesis is that running creates greater loading forces than walking even at the same aerobic intensity. Young adults (10 M and 10 F; age, 22.8 ± 0.5 years) performed 3 exercise trials in a counter-balanced order: walking 5.5 kph at 0% grade (WH); walking 5.5 kph at 11% (WI); and running at 8.0 kph at 0% (R). Oxygen consumption (V[Combining Dot Above]O2), step frequency, peak vertical ground reaction force (VGRF), and vertical force loading rate were recorded during th...

Acute Response of PGC-1α and IGF-1 Isoforms to Maximal Eccentric Exercise in Skeletal Muscle of Postmenopausal Women

Sat, 26 Mar 2016 10:25:17 +0100

Abstract: Dieli-Conwright, CM, Kiwata, JL, Tuzon, C, Spektor, TM, Sattler, FR, Rice, JC, and Schroeder, ET. Acute response of PGC-1α and IGF-1 isoforms to maximal eccentric exercise in skeletal muscle of postmenopausal women. J Strength Cond Res 30(4): 1161–1170, 2016—PGC-1α4, a novel isoform of the transcriptional coactivator PGC-1α, was recently postulated to modulate the expression of anabolic and catabolic genes and therefore regulate skeletal muscle hypertrophy. Resting levels of PGC-1α4 messenger RNA (mRNA) expression were found to increase in healthy adults after resistance training. However, the acute effect of resistance exercise (RE) on PGC-1α4 expression in populations prone to progressive muscle loss, such as postmenopausal women, has not been evaluated. Here, we inves...

Cytokine Signaling in Skeletal Muscle Wasting

Fri, 25 Mar 2016 23:00:00 +0100

Publication date: Available online 26 March 2016 Source:Trends in Endocrinology & Metabolism Author(s): Jin Zhou, Bin Liu, Chun Liang, Yangxin Li, Yao-Hua Song Skeletal muscle wasting occurs in a variety of diseases including diabetes, cancer, Crohn's disease, chronic obstructive pulmonary disease (COPD), disuse, and denervation. Tumor necrosis factor α (TNF-α) is involved in mediating the wasting effect. To date, a causal relationship between TNF-α signaling and muscle wasting has been established in animal models. However, results from clinical trials are conflicting. This is partly due to the fact that other factors such as TNF-like weak inducer of apoptosis (TWEAK) and interleukin 6 (IL-6) are also involved in skeletal muscle wasting. Because muscle wasting is often a...

Comparison of the impact of closing wedge versus opening wedge high tibial osteotomy on proximal tibial deformity and subsequent revision to total knee arthroplasty

Fri, 25 Mar 2016 23:00:00 +0100

Conclusion The difference in the post-operative angular deformities of the proximal tibia between CW-HTO and OW-HTO was considered to be clinically irrelevant. The risk of interference between TKA tibial implant and endosteal bone was greater after CW-HTO than after OW-HTO. For clinical relevance, the difference between the two techniques has little influence on subsequent TKA difficulty regarding the proximal tibial deformity, although preoperative planning is obligatory, particularly after CW-HTO, to prevent interference with the tibial implant.

The medial border of the tibial tuberosity as an auxiliary tool for tibial component rotational alignment during total knee arthroplasty (TKA)

Fri, 25 Mar 2016 23:00:00 +0100

Conclusion This study found that in 90 % of the patients, the medial border of the tibial tuberosity is internally rotated 17°–24° in relation to the line connecting the middle of the tuberosity to the tibial geometric centre. Since this anatomical landmark may be more easily identifiable intraoperatively than the commonly used “medial 1/3”, it can provide a better quantitative reference point and help surgeons achieve a more accurate tibial implant rotational position.

The Etiology and Arthroscopic Surgical Management of Cam Lesions

Fri, 25 Mar 2016 23:00:00 +0100

Cam-type deformity of the proximal femur is a relative increase in the discrepancy of the femoral head–neck offset. The etiology is unknown; several conditions have been implicated in the development of abnormal proximal femoral anatomy. Recent evidence suggests that high-impact sports place stress on the immature physis during growth may play an important role. Imaging is essential in the initial diagnostic workup, characterization of pathology, preoperative planning, and intraoperative decision making. Short-term and mid-term outcomes for arthroscopic osteoplasty of cam lesions for both isolated cam-type deformity and mixed cam–pincer femoroacetabular impingement have been well-described and are favorable.

Consider This Before You Sign Up For A HIIT Class

Fri, 25 Mar 2016 21:11:21 +0100

High-intensity workouts are all the rage, and for good reason: They burn more calories than standard cardio, can boost your endurance and and increase the elasticity of your arteries and veins, which is really terrific for your heart. But according to a new study published in Federation of American Societies for Experimental Biology Journal, for all of HIIT's benefits, there's a catch: The workout could do more harm than good if you're new to exercise.  (Don't try that at home.)

Regular exercise alleviates renovascular hypertension-induced cardiac/endothelial dysfunction and oxidative injury in rats.

Fri, 25 Mar 2016 19:51:02 +0100

Authors: Kumral ZN, Sener G, Ozgur S, Koc M, Suleymanoglu S, Hurdag C, Yegen BC Abstract The importance of physical activity in the management of renovascular diseases is well-known, but lacks evidence of underlying mechanisms. The purpose of the study was to elucidate the protective/therapeutic effects of regular exercise on experimental renovascular hypertension (RVH)-induced oxidative stress and cardiac dysfunction. Wistar albino rats underwent a RVH surgery (2K1C, Goldblatt). Three weeks later half of the rats started swimming exercise for 9 weeks (n = 15), while the sedentary RVH group (n = 15) had no exercise during that period. Sham-operated control rats (n = 10), had the similar surgical procedures but the left renal artery was left unclipped. Body weights were monitored, a...

Men With Psoriasis Could Be More Likely To Have This Sexual Problem

Fri, 25 Mar 2016 17:18:45 +0100

(Reuters Health) - Men with psoriasis may be more prone to erectile dysfunction than their peers without this skin disease, and their odds of sexual difficulties are even higher if they are depressed or have other health problems like diabetes or high blood pressure, a Chinese study suggests.  Researchers studied sexual function in 191 patients with psoriasis and an equal number of healthy men. They found 53 percent of the men with psoriasis reported erectile dysfunction, compared with 40 percent in the healthy control group. Men with psoriasis were significantly more likely to report severe erectile dysfunction, while the men without the condition were much more apt to describe milder difficulties. When men with psoriasis do develop erectile dysfunction, they may be able to improve t...

People who experience the most severe type of heart attack have become younger and more obese in the past two decades, according to a new study. This group is also increasingly more likely to smoke, and to have high blood pressure and diabetes, all of which are preventable risk factors for a heart attack, the researchers found. "On the whole, the medical community has done an outstanding job of improving treatments for heart disease, but this study shows that we have to do better on the prevention side," study co-author Dr. Samir Kapadia, an interventional cardiologist at Cleveland Clinic, said in a statement. "When people come for routine checkups, it is critical to stress the importance of reducing risk factors through weight reduction, eating a healthy diet and being physically active."...

Antibiotics Side Effects on the Mitochondria

Fri, 25 Mar 2016 15:38:08 +0100

Science is just beginning to understand how important your mitochondria are to warding off the diseases of aging. And, as usual, mainstream medicine is lagging way behind. Along with your telomeres, the cellular time keepers at the ends of your chromosomes, your mitochondria are another key component of the anti-aging equation. You see, these tiny organelles in your cells are the power plants that turn fuel into energy for your body. Healthy mitochondria keep you young and energetic.  Research shows that damaged mitochondria can lead to: Schizophrenia and bipolar disorder; Alzheimer’s and Parkinson’s disease; Epilepsy, migraines, and nerve pain; Loss of muscle control and balance; Strokes, heart disease, and coronary artery disease; Chronic fatigue syndrome and fibromyalgia;...

Cat Parasite Linked To Angry Outbursts In People

Fri, 25 Mar 2016 12:47:24 +0100

CHICAGO (CBS) – Feeling inexplicably angry? Your cat may be to blame. CBS News reports that researchers at the University of Chicago have linked cases of irrational anger in people to a parasite that is commonly found in cats. The parasite called toxoplasma gondii and can be passed from felines to humans through cat feces (take care when cleaning the litter box!) The Centers For Disease Control says about 60 million people have the parasite, and it’s thought to be pretty harmless. But now, scientists believe there’s a connection between the parasite and a psychiatric disorder called Intermittent Explosive Disorder. Those with IED can exhibit rage in response to events that really don’t merit such an aggressive response. Read More From The Study “Our work suggests that latent ...

Pretty Much Nobody In The U.S. Leads A Healthy Lifestyle

Fri, 25 Mar 2016 12:45:07 +0100

Only 2.7 percent of U.S. adults hit the four key metrics of living a healthy lifestyle -- abstaining from smoking, eating well, exercising and maintaining a healthy body fat percentage -- according to a disheartening new study. The study's lifestyle benchmarks for health weren't particularly high. Being smoke-free, exercising moderately and eating USDA recommended foods don't seem like particularly difficult marks to hit. So why do so many Americans fall short of living healthy lives?  "That is the million dollar question," Ellen Smit, a senior author of the study and an associate professor at the Oregon State University College of Public Health and Human Sciences, told The Huffington Post. "We did not look at why few Americans have healthy lifestyles in this study, but I can spe...

[Comment] Left-to-right atrial shunting: new hope for heart failure?

Fri, 25 Mar 2016 12:07:08 +0100

So far, no treatments have proven effective for heart failure with preserved ejection fraction—a syndrome with dismal prognosis.1 The syndrome is heterogeneous and associated with many comorbidities. Pathophysiology of the disorder is poorly understood, although a common hallmark is large artery stiffness and heart stiffness, whether related to fibrosis or myocardial titin-based stiffness. As a consequence, the heart's ability to cope with exercise-induced haemodynamic overload is restricted. Exercise would inevitably produce an abrupt rise in pulmonary and left atrial pressure, the main driver of dyspnoea in patients with heart failure with preserved ejection fraction. (Source: LANCET)

Fri, 25 Mar 2016 12:07:08 +0100

Implantation of an interatrial shunt device is feasible, seems to be safe, reduces left atrial pressure during exercise, and could be a new strategy for the management of HFPEF. The effectiveness of IASD compared with existing treatment for patients with HFPEF requires validation in a randomised controlled trial. (Source: LANCET)
