5th edition under way….

Thanks to all of you who have had many great things to say about the 4th edition and the work of the 115 awesome contributors.

The good news is that 150+ contributors have been working on the 5th edition which is part finished. The 5th edition will come in two volumes. Volume 1 is the “Sports Injuries” part and it should be released late in 2016.

Volume 2, “Sports & Exercise Medicine” will come out separately – we are working on one book at a time. We are confident you will love Volume 1 of 5th edition – complete renovation!

This website will be pretty inactive while we focus on getting the book finished.

Artificial turf in elite soccer, new finding give rise to new questions ~ Karolina Kristenson, MD PhD

Does artificial turf (AT) affect injury rates in football (soccer)? It is a question widely debated. Robust data states that artificial turf does not affect the general injury rate for acute injuries. Few studies, however, have included overuse injuries when comparing injury rates with AT and natural grass (NT).  Also, the aspect of rapid change between surfaces is often discussed among football players, trainers and clinicians, but no previous studies have evaluated whether this actually affect injury rates.

With this background, our research group (Football Research Group, Linköping Sweden) and The Oslo Sports Trauma Research Group (Oslo, Norway) initiated a research project. We thought that a study setting in the Swedish and Norwegian first male leagues was appropriate since a) artificial turf is common in the Nordic countries, and b) the leagues are similar in climate and standards. In this way, we could collect a larger data set, which is a prerequisite to be able to analyze injury pattern, such as the injury rate for different specific muscle groups.

During two full football seasons (2010 and 2011), we recorded injuries that led to absence from football as well as player’s individual exposure to football on grass and AT. In November 2011, we could sum up that 32/37 clubs playing in the first leagues during this period had participated for the full study period. This resulted in 1063 match injuries and 1178 training injuries registered during 48,922 match and 318,568 training hours.

We compared the acute injury rates on AT and NG at the individual player level (to see if this study would replicate the findings from previous studies). Also, in this study setting we were able to compare acute and overuse injury rates between clubs that have artificial turf at their home venue (AT clubs) and clubs that have natural grass (NG clubs).

Interestingly, the result we found was that professional football clubs with AT installed at their home venue had a higher acute training injury rate and overuse injury rate compared to clubs with NG. In particular, AT clubs had a higher rate of overuse injuries to the hip/adductors (60% increase) and calf (four-fold increase).

Also, AT clubs had a higher match injury rate during the competitive season, while no differences between AT clubs and NG clubs were found during pre-season. Still, at the individual level, no differences in acute injury rates were found when playing on AT compared to NG in the total cohort analysis.

Consequently, our study replicated the findings from previous research that there is no difference in the acute injury rate at the two surfaces, yet clubs playing home matches on AT have a higher injury rate. Why is that?

Our hypothesis is that the AT clubs´ higher injury rates could be due to a rapid switching between playing surfaces and inadequate adaptation to a new surface. Since there were fewer AT clubs than NG clubs in this cohort, players from AT clubs had to alternate between surfaces more often when playing away matches.

It is possible that such frequent shifts between surfaces could lead to a greater load on musculoskeletal tissues and an increased overuse injury rate. This could explain why a higher match injury rate for AT clubs was only evident during the competitive season when switching between surfaces at away matches occurred frequently, while match injury rates were similar during the pre-season, when most friendly matches were played on AT.

Of course, many questions still remain to be answered. Sweden and Norway are located in the northern part of Europe and cross several climate zones. It is possible that clubs with AT installed at their home venue could have chosen this surface because of the rough climate conditions, i.e. a generally colder climate, which itself could influence injury rates. It is also possible that clubs chose AT turf at their home venue because of the saving in costs. Therefore, the role of climate and clubs economy as a potential risk factor needs to be addressed in future studies.

Dr Karolina Kristenson is a PhD graduate in Football Research Group (FRG), Linköping University, Sweden. FRG has conducted injury studies since 2001 in cooperation with the Union of European Football Associations (UEFA). These cohorts include clubs playing in the UEFA Champions League, English Premier League and the Nordic top leagues. Her thesis focus on injury rate in elite football related to playing surface.

“Do you even lift, Bro?” ~ Ann Gates @exerciseworks

The recent viral videos and ‘outtakes’ of the responses to this pertinent (and yes, hilariously funny) rhetorical question got me thinking… what a great question to trend in the fight against the type 2 diabetes epidemic.

Type 2 diabetes is largely preventable and treatable with the right medicines, a healthy, balanced diet and regular daily exercise. Recent studies show that adding in resistance or ‘strength’ training confers significant results in the overall management and health outcomes of Type 2 diabetes. Two particular studies warrant highlighting:

  • The Umpierre, 2011 study clearly shows that a structured exercise plan including strength training, is associated with greater health outcomes including a significant HbA(1c) reduction in patients with type 2 diabetes than with exercise plans without strength training. Structured exercise training such as aerobic exercise, resistance training, or both combined of more than 150 minutes per week is associated with greater HbA(1c) declines and is also  a cost effective management approach in type 2 diabetes.However, the physical activity advice is associated with lower HbA(1c) only when combined with dietary advice. This adds even more weight to the question ‘do you even lift. Bro?’ The study clearly demonstrates that a combination of cardiovascular exercise and strength training improves the overall management and cost effectiveness of type 2 diabetes care.
  • The second study of interest showed that men who do strength (resistance) training regularly—for example, for 30 minutes per day, five days per week—may be able to reduce their risk of type 2 diabetes by up to 34 percent. In this new 2012 study, by Harvard School of Public Health (HSPH) and University of Southern Denmark researchers also combined strength training and aerobic exercise, such as brisk walking or running, and showed that men may be able to reduce their type 2 diabetes risk even further—up to 59 percent!

59 percent reduction of risk of type 2 diabetes is surely something that all health commissioners, doctors, sports and exercise specialists, allied health professionals and patients at risk of developing type 2 diabetes should be aiming for with structured exercise plans and lifestyle advice.

In fact, wouldn’t it be fantastic if patients actually knew this benefit of a regular exercise plan including strength exercises as part of routine exercise plans in the prevention and treatment of type 2 diabetes? Wouldn’t it be a great idea to use social media in this way, to get the message over to health professionals and their patients that yes … medically and scientifically……..strength training works!

So actually, as dangerous as asking the question is, ‘Do you even lift, Bro?’ (you have to watch the videos to really appreciate the risks of this scenario….!).

The enlightened answer is…

 “Bro….. I lift because it reduces my risks of type 2 diabetes by 39 percent, I run because it reduces those risks further by 25 percent, I also add in balance and flexibility training ‘cause man… that really helps you feel good in yourself…… I combine all of this with a healthy diet….”

And the outtakes may well result in better national, local and individual health in the management of type 2 diabetes!

Strength training support should be offered to all patients at risk of type 2 diabetes.
