Preventing & Managing Ankle Sprains

Posted by Dr. Emily Kraus on Apr 8, 2017 8:05:00 AM

Soccer is currently the most popular sport played worldwide and it also, not surprisingly, happens to have the highest injury rate among high school sports, with ankle sprains occurring most frequently. Ankle sprains are a common injury in the sports world, comprising approximately 25% of all sports-related injuries.1 A prior ankle sprain is one of the greatest risk factors for a future sprain, so both prevention and optimal management of acute (new) sprains is essential. This article will briefly review the anatomy and mechanism of an ankle sprain, management options, and finally prevention strategies.

Vitamin D: A Key Player in Bone Health, Sports Performance, & Recovery

Posted by Dr. Emily Kraus on Feb 13, 2017 9:44:02 AM


With the high amounts of snow and rain this winter, it’s been especially challenging to get outdoors, raising an important question: are you getting enough Vitamin D? Studies have found that 56% of athletes have inadequate Vitamin D levels.1 Vitamin D, commonly referred to as the “Sunshine Vitamin” is not only essential for normal body function, but new research on athletes demonstrates an important role in sports performance and injury prevention. This article will focus on how athletes acquire and metabolize Vitamin D, its effects on performance parameters, bone health and immunity, and the controversy of optimal levels and supplementation.

Serve Up a Winning Season through ACL Injury Prevention

Posted by Dr. Emily Kraus on Dec 20, 2016 5:17:27 PM

Whether you’re an athlete, coach, athletic trainer, or just an avid sports fan, you likely know someone with an injury to her or his anterior cruciate ligament (ACL) or you may have been in the unfortunate situation to experience the injury firsthand. ACL injuries are a common sports-related injury with an annual incidence of 120,000, occurring primarily during the high school and college years.1 Even more shocking is that this rate is increasing, especially in females. This article will focus on ACL injuries in the female athlete (although many recommendations can be applied to both sexes), with discussion on the science behind the injury, the debate on management options, and prevention strategies.

Low Back Pain in the Athlete: Swimmer’s Special

Posted by Dr. Emily Kraus on Oct 18, 2016 3:59:01 PM

When a swimmer explodes off the starting blocks, each muscle needs to be firing in the proper sequence with full mobility to perform at the top level. Low back pain (LBP) can greatly hinder both performance and mobility. Although not as common as shoulder injuries, studies report low back injuries in 16% of elite swimmers,1 while other studies have reported much higher rates, ranging from 77%-87% in both high load and recreational swimmers.2 Low back pain affects swimmers of all ages, from the novice to elite level. This article will take you through a brief review of the anatomy and function of the back, causes and risk factors for LBP, and finally prevention and management strategies.

Beat the Heat: Cooling Methods and Exertional Heat-Related Illness

Posted by Dr. Emily Kraus on Aug 29, 2016 12:02:29 PM


Okay, so you’ve fully acclimated yourself to the heat and mastered your hydration plan. You’re almost ready to take on the blisteringly hot, swelteringly humid conditions of competition. A discussion on heat training would not be complete without addressing cooling methods and early identification of exertional heat-related illness.

How to Beat the Heat in Training and Competition: Part 2 - Hydration

Posted by Dr. Emily Kraus on Aug 8, 2016 1:25:44 PM

Part II: Hydration

The month of August brings the commencement of major international competitions and Fall sports practices. August also brings with it some of the hottest and most humid days of the year, which makes for a well-timed continuation of the discussion on how to optimize performance when training and competing in the heat. Part one focused on the benefits of heat acclimatization on thermoregulation for optimal performance, but proper hydration can truly make or break an athlete come game day. In this article, I will discuss why hydration is so important and then provide simple hydration strategies before, during, and after exercise.

How to Beat the Heat in Training and Competition: Part 1 - Acclimatization

Posted by Dr. Emily Kraus on Jul 14, 2016 8:30:00 AM

Part I: Heat Acclimatization

As the summer temps heat up, so does the competition. With so many high stakes national and international events taking place this summer, athletes are feeling the pressure of competition. If that wasn’t enough, add the environmental demands of heavy, suffocating humidity or that blinding, blistering sun. In this two-part series, I hope to provide some insight into how you can beat the heat and (hopefully) your competition starting with heat acclimatization education and strategies (part I) followed by proper hydration and cooling methods and how to recognize early signs of heat exhaustion, a potentially dangerous clinical scenario (part II).

Preventing & Treating Exercise Associated Muscle Cramps (EAMC)

Posted by Dr. Emily Kraus on May 12, 2016 9:00:00 AM

Muscle cramps can be a royal pain in the rear….and hamstring, calf, quad, … the list goes on. Even with the most disciplined training, fueling and hydration plan, a bad cramp can still find a way to hold you down on the day of a competition and completely change your performance. In fact, it is one of the most common medical problems encountered by competitors in an Ironman or any other ultra-distance event as well as affecting athletes of many other sports – especially during the conditioning phases early in pre-season training.

Swimmer’s Shoulder-Prevention and Training Strategies | BridgeAthletic

Posted by Dr. Emily Kraus on Jan 16, 2015 3:11:24 PM

In the culture of swimming, it’s often expected to “train through the pain” in order to get to the top1. If you consider yourself a competitive swimmer, you likely have experienced shoulder pain at some point in your career, with it being the most common musculoskeletal complaint in swimming with an incidence ranging from 52% to 73% in elite swimmers2. A competitive swimmer usually exceeds 4000 strokes for one shoulder in a single workout3! Needless to say, the shoulder can make or break a swimmer’s season and athletes should focus on prevention to avoid a season-ending injury.

Swimmer’s shoulder usually involves impingement or pinching of the rotator cuff muscles by the acromion bone as they pass through a narrow opening called the subacromial space (see figure below).
