ACL re-injury risk factors: a new study
“Our research suggests that a few risk factors such as, age, activity level and type of graft utilized may point to the possibility of re-injury,” said lead author, Christopher C. Kaeding, MD of the Ohio State University. “However, with better education about adjustments that can be made, based on these risk factors, patients may be able to minimize re-tears.”
Kaeding and his team analyzed data from 2,695 patients through the MOON ACL injury database from 2002-2008. All patients had a primary ACL reconstruction with no history of contralateral knee surgery. Graft type, age, Mark score, sport played after surgery, sex, smoking status, meniscal tear status and Body Mass Index (BMI) were identified as criteria for inclusion into the study.
In the results, 116/2695 (4.3%) had a graft re-tear on the same side of the body and 97/2695 (3.6%) had a re-tear on the opposite side. The odds of re-tearing the same ACL, decreased by nine percent for each year of increased age. The odds of re-tear on the opposite ACL, decreased by four percent for every year of increased age.
“The study highlights that younger age, higher activity levels at time of injury and what type of graft used (allograft) may increase risk of same side ACL injury within two years. With individuals having higher activity levels and lower age re-tears on the opposite leg were more prominent,” said Kaeding. “Physicians and physical therapists need to better educate our patients about continued neuro-muscular training even after the immediate rehabilitation process has ended to help prevent future tears.”

Barefoot running improves running economy at high exercise intensities
Posted on July 8, 2014 by Stone Hearth News
J Sports Med Phys Fitness. 2014 Jul 7. [Epub ahead of print]
Barefoot running improves economy at high intensities and peak treadmill velocity.
Reeves KA1, Corbett J, Barwood MJ. Author information 1Department of Sport and Exercise Science, University of Portsmouth, Hampshire, UK – kevin.reeves@myport.ac.uk.
Abstract
AIM:
Barefoot running can improve running economy (RE) compared to shod running at low exercise intensities, but data is lacking for the higher intensities typical during many distance running competitions. The influence of barefoot running on the velocity at maximal oxygen uptake (vVO2max) and peak incremental treadmill test velocity (vmax) is unknown. The present study tested the hypotheses that barefoot running would improve RE, vVO2max and vmax relative to shod running.
METHODS:
Using a balanced within–subject repeated measures design, eight male runners (aged 23.1±4.5 years, height 1.80±0.06 m, mass 73.8±11.5 kg, VO2max 4.08±0.39 L·∙min–1) completed a familiarisation followed by one barefoot and one shod treadmill running trial, 2–14 days apart. Trial sessions consisted of a 5 minute warm–up, 5 minute rest, followed by 4×4 minute stages, at speeds corresponding to ~67, 75, 84 and 91% shod VO2max respectively, separated by a 1 minute rest. After the 4th stage treadmill speed was incremented by 0.1 km·h–1 every 15 s until participants reached volitional exhaustion.
RESULTS:
RE was improved by 4.4±7.0% across intensities in the barefoot condition (p=.040). The improvement in RE was related to removed shoe mass (r2=.80, p=.003) with an intercept at 0% improvement for RE at 0.520 kg total shoe mass. Both vVO2max (by 4.5±5.0%, p=.048)and vmax (by 3.9±4.0%, p=.030) also improved but VO2max was unchanged (p=.747).
CONCLUSION:
Barefoot running improves RE at high exercise intensities and increases vVO2max and vmax, but further research is required to clarify the influence of very light shoe weights on RE.

Sitting Too Much, Not Just Lack of Exercise, Is Detrimental to Cardiovascular Health
The study, published in today’s online edition of Mayo Clinic Proceedings, examined the association between fitness levels, daily exercise, and sedentary behavior, based on data from 2,223 participants in the National Health and Nutrition Examination Survey (NHANES).
Sedentary behavior involves low levels of energy expenditure activities such as sitting, driving, watching television, and reading, among others. The findings suggest that sedentary behavior may be an important determinant of cardiorespiratory fitness, independent of exercise.

“Previous studies have reported that sedentary behavior was associated with an increased risk for cardiovascular outcomes; however, the mechanisms through which this occurs are not completely understood,” said Dr. Jarett Berry, Assistant Professor of Internal Medicine and Clinical Science and senior author of the study. “Our data suggest that sedentary behavior may increase risk through an impact on lower fitness levels, and that avoiding sedentary behavior throughout the day may represent an important companion strategy to improve fitness and health, outside of regular exercise activity.”
“We also found that when sitting for prolonged periods of time, any movement is good movement, and was also associated with better fitness,” said Dr. Jacquelyn Kulinski, a recent graduate from the UT Southwestern Cardiology Fellowship Training Program and first author of the paper. “So if you are stuck at your desk for a while, shift positions frequently, get up and stretch in the middle of a thought, pace while on a phone call, or even fidget.”
NHANES is an ongoing series of studies conducted by the National Center for Health Statistics and the Centers for Disease Control and Prevention. The database contains health and nutritional data from a diverse population, representative of the U.S. population.
Other UT Southwestern researchers involved in the study include Dr. Amit Khera, Director of the Preventive Cardiology Program and Associate Professor of Internal Medicine; Dr. Sandeep Das, Assistant Professor of Internal Medicine; Dr. James de Lemos, Associate Program Director of the Cardiology Fellowship Program and Professor of Internal Medicine; and Colby Ayers, Faculty Associate in the Department of Clinical Science.
This study was funded with support from the National Heart, Lung and Blood Institute, the American Heart Association, and an unrestricted endowment provided to Dr. Berry by the Dedman Family.
7 ways to keep kids hydrated
Posted on July 8, 2014 by Stone Hearth News
Brita 35530 Ultramax Dispenser (Reuters Health) –
Don’t wait for your kids to tell you they’re thirsty before offering them water, experts say. Instead, offer them water and other hydrating foods and beverages throughout the day, particularly in the summer when more liquids are needed to stay healthy.
By the time children are thirsty, they’re already at least 3 percent dehydrated, according to Dr. Holly Benjamin, Associate Professor of Pediatrics and Orthopedic Surgery at University of Chicago. And water does far more than slake thirst, said Marina Chaparro, spokesperson for the Academy of Nutrition and Dietetics.
“Water is a cooling mechanism, it transports fluids and nutrients, helps with digestion, helps with cognitive function and maintains a healthy weight,” she told Reuters Health by email.
The amount of water a child needs to stay hydrated and healthy may surprise you: teenagers need as much as adults (eight to 11 cups), while even toddlers aged 1 to 3 should have four cups of fluids a day.
“I use a rule of thumb of 2 to 3 ounces per day per pound of body weight, to a maximum of 8 to 10 cups per day,” said Dr. Karl W. Holtzer, a pediatrician with the Pediatric Alliance Fox Chapel Division in Pittsburgh.
In email to Reuters Health, he noted that water is not needed for infants under 6 months of age, and babies under 1 year can stay hydrated with breast milk or formula.
