ACL re-injury risk factors: a new study

 


  
SEATTLE, WA – Re-tearing a repaired knee Anterior Cruciate Ligament (ACL) happens all too frequently, however a recent study being presented today at the American Orthopaedic Society for Sports Medicine’s (AOSSM) Annual Meeting suggests that identification and patient education regarding modifiable risk factors may minimize the chance of a future ACL tear.
“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

 

 

  
Newswise — Dallas – July 7, 2014 – Cardiologists at UT Southwestern Medical Center found that sedentary behaviors may lower cardiorespiratory fitness levels. New evidence suggests that two hours of sedentary behavior can be just as harmful as 20 minutes of exercise is beneficial.
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.”
  
The team of physician-researchers analyzed accelerometer data from men and women between the ages of 12 and 49 with no known history of heart disease, asthma, or stroke, and measured their average daily physical activity and sedentary behavior times. Fitness was estimated using a submaximal treadmill test, and variables were adjusted for gender, age, and body mass index. The findings demonstrate that the negative effect of six hours of sedentary time on fitness levels was similar in magnitude to the benefit of one hour of exercise.
“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.”
  
To stay active and combat sedentary behavior, UT Southwestern preventive cardiologists recommend taking short walks during lunch and throughout the day, using a pedometer to track daily steps, taking the stairs instead of the elevator, hosting walking meetings at work, and replacing a standard desk chair with a fitness ball or even a treadmill desk, if possible.
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.

UPRISING PROMOTIONS ADDS THREE TALENTED FIGHTERS TO STABLE
Lightweight Wesley Ferrer, Super Featherweight Angel Luna and Junior Welterweight Darren Mangan Join Rapidly Growing Promotion

Brooklyn, N.Y. -
New York-based Uprising Promotions has made a huge statement on the boxing circuit, announcing the addition of three highly skillful fighters to its talented roster. Officially joining the stable is undefeated Brooklyn lightweight Wesley Ferrer (4-0, 3 KOs), unbeaten Dominican super featherweight Angel Luna (9-0, 6 KOs) and highly sought-after Irish junior welterweight Darren Mangan.

"I am very excited. I believe in these guys, and I am a great judge of boxing talent," said Ronson Frank, President of Uprising Promotions. "I think all three of these guys have the ability to take not only themselves, but also us as a promotion, to the next level where we can compete with all of the big name promoters out there."

Under the guidance of his father, Mateo De La Cruz, Wesley Ferrer had a very accomplished amateur career, winning his first NY Daily News Golden Gloves Championship in 2009 when he was merely 17-years-old. He continued on that same successful path until deciding to turn in his amateur card for the professional ranks in September of 2013. His pro debut lasted just 31 seconds when he scored a TKO victory over Masaki Aida on a card hosted by Uprising Promotions. The Brooklyn native has since recorded three more wins, two by early stoppage, with two of those outings under the Uprising Promotions banner.

After eight bouts in his home of the Dominican Republic, Angel Luna made his American debut on May 21st when he fought on an Uprising Promotions card, defeating Joey Arroyo by second round TKO. Of his nine professional contests, Luna has earned six victories inside the allotted timeframe, and he now looks to make an impression on the New York fight scene under the guidance of Uprising Promotions.

"These fighters are great character guys who work very hard in the gym," Frank continued. "Wesley Ferrer is a very intelligent guy who is currently a college student. Angel Luna is a very dedicated guy in the gym. His trainer tells me all the time that he has to tell him to tone it down."

The final signing by Uprising Promotions is highly regarded junior welterweight Darren Mangan, who moved to New York from his native Ireland just a few weeks ago. Fighting out of Gotham Boxing, which is located at 600 Washington Street in the West Village, he looks to make his professional debut under the Uprising Promotions banner later this year.

"Darren is so excited, and he calls me every day to let me know what type of progress he is making," Frank laughed. "He is a 19-year-old kid who is very excited about the opportunity to be here and looks forward to performing on the biggest stage in boxing."

Growing up in Castlebar before spending the last seven years of his life in Letterkenny, Ireland, Mangan arrives in New York with nearly 100 amateur bouts on his resume. The extremely personable fighter was highly sought after by a number of promoters but decided Uprising Promotions was the best place for him. As he begins the preparation for his professional debut, the 19-year-old Irishman will be working with internationally renowned trainer Colin Morgan, who has trained the likes of current WBO Middleweight Champion Peter Quillin, former WBA Cruiserweight Champion Guillermo Jones, former WBC Featherweight Champion Elio Rojas, as well as undefeated heavyweight contender Mike Perez.

"I am delighted and over the moon to sign with Uprising Promotions," Mangan emphatically stated. "If you told me a couple of years ago that I would be fighting in New York City at 20 years of age, I don't think that I would have believed you. I've been here for more than two weeks now, and I'm settling in well. I can't wait to start working with a world renowned trainer in Colin Morgan. We have a really good team around me, and I am seriously excited to hook up with Ronson and Uprising Promotions. There were a few offers on the table, especially since I am a young fighter with a lot of amateur experience, but this was the best fit for me."

As he engulfs on his professional career, Mangan hopes to follow in the footsteps of another Irish fighter who was able to win over the entire City of New York.

"A fight town like New York needs another Irish fighter! It has really been since John Duddy retired that an Irish fighter was at the top here, and I think Ronson is the right guy to get me there. He is hungry to expand my career and Uprising Promotions, and we have the right people around us to make that happen."

The date for the next Uprising Promotions fight card has already been set, with the promotion returning to action on September 13th. Negotiations are underway with a few different venues in New York for the event, and the location announcement will be made in the very near future.

When Is Exercise an Addiction or Healthy Lifestyle Choice?

When Is Exercise an Addiction or Healthy Lifestyle Choice?

 
 

  
Individuals With Exercise Addiction Often Struggle With Co-occurring Disorders; 15 to 20 Percent of Exercise Addicted Individuals Are Also Dependent on Nicotine, Alcohol, or Illicit Drugs
CHICAGO, IL–(Marketwired – June 19, 2014) – Exercising on a regular basis is beneficial. It contributes to health and disease prevention and has a positive effect on mental and physical well-being for all age groups. There are instances, however, where exercise becomes an addiction.
“Exercise addiction is a process addiction in which a person engages in compulsive, mood-altering behaviors with the intention of avoiding painful feelings,” said Kim Dennis, MD, CEO and medical director of Timberline Knolls Residential Treatment Center. “Those addicted to exercise chase the ‘high,’ and this behavior ultimately becomes unmanageable and destructive.”
The prevalence of exercise addiction in the general population is close to three percent, but is higher among ultra-marathon runners and sport science students. Exercise addiction also tends to cluster with food disorders, caffeine use, and shopping. Work addiction is also another co-occurring disorder.
Dr. Dennis adds certain criteria must be met for a behavior to be considered an addiction. Those include:
  
  • Tolerance: increasing the amount to feel the desired effect
  • Withdrawal: negative effects such as anxiety, irritability, restlessness, and sleep problems, when exercise is stopped
  • Lack of control: attempts to reduce exercise fail
  • Intention: unable to adhere to intended routine
  • Time: a great deal of time is spent preparing for, engaging in, and recovering from exercise
  • Reduction in other activities: social, occupational, and/or recreational activities are reduced
  • Continuance: continuing despite negative physical, psychological, and/or interpersonal consequences
Individuals with exercise addiction often have food disorders, caffeine use, and other process disorders such as work and shopping addiction. It is not unusual for them to experience depression, trauma, generalized anxiety disorder, and obsessive compulsive disorder. In addition, individuals with eating disorders often engage in excessive exercise. It is estimated that 39 to 48 percent of people suffering from eating disorders also suffer from exercise addiction.
“As with many addictions, dependence on exercise can start innocently,” adds Dr. Dennis. “The individual often receives validation or reinforcement for exercising. Once an individual is hooked, a need to achieve the euphoric state eclipses all else. Work, family, and social life frequently take a back seat to the necessity of exercising. If deprived, we see withdrawal symptoms just like you would with any other addiction.”
  
Treatment is available and recovery from exercise addiction is possible. In time, reasonable, healthy and beneficial exercise can be reintroduced as part of a balanced life.
About Timberline Knolls:
Timberline Knolls is a leading private residential treatment center for women and adolescent girls (ages 12 – 65+) with eating disorders, substance abuse, trauma, mood and co-occurring disorders. Located in suburban Chicago, residents receive excellent clinical care from a highly trained professional staff on a picturesque 43-acre wooded campus. Women and families seeking Christian treatment can opt for specialized Christian-based therapy.

Dance may be an effective strategy to implement physical activity in motivated subjects with type 2 diabetes or obesity

Posted on June 22, 2014 by Stone Hearth News



A standard ballroom and Latin dance program to improve fitness and adherence to physical activity in individuals with type 2 diabetes and in obesity

 Felice Mangeri, Luca Montesi, Gabriele Forlani, Riccardo Dalle Grave and Giulio Marchesini Diabetology & Metabolic Syndrome 2014, 6:74 doi:10.1186/1758-5996-6-74 Published: 22 June 2014

Abstract (provisional)

Objective

To test the effectiveness of a dance program to improve fitness and adherence to physical activity in subjects with type 2 diabetes and obesity.

Research Design and Methods

Following a motivational interviewing session, 100 subjects with diabetes and/or obesity were enrolled either in a dance program (DP, n = 42) or in a self-selected physical activity program (SSP, n = 58), according to their preferences. Outcome measures were reduced BMI/waist circumference, improved metabolic control in type 2 diabetes (-0.3% reduction of HbA1c) and improved fitness (activity expenditure >10 MET-hour/week; 10% increase in 6-min walk test (6MWT)). Target achievement was tested at 3 and 6 months, after adjustment for baseline data (propensity score).

Results

 Attrition was lower in DP. Both programs significantly decreased body weight (on average, -2.6 kg; P < 0.001) and waist circumference (DP, -3.2 cm; SSP, -2.2; P < 0.01) at 3 months, and the results were maintained at 6 months. In DP, the activity-related energy expenditure averaged 13.5 +/- 1.8 MET-hour/week in the first three months and 14.1 +/- 3.0 in the second three-month period. In SSP, activity energy expenditure was higher but highly variable in the first three-month period (16.5 +/- 13.9 MET-hour/week), and decreased in the following three months (14.2 +/- 12.3; P vs. first period < 0.001). At three months, no differences in target achievement were observed between groups. After six months the odds to attain the MET, 6MWT and A1c targets were all significantly associated with DP.

Conclusion

Dance may be an effective strategy to implement physical activity in motivated subjects with type 2 diabetes or obesity (Clinical trial reg. no. NCT02021890, clinicaltrials.gov)
