Baseball & Nordic exercises: Preventing Injury

By |2020-02-27T10:41:10-05:00February 27th, 2020|Baseball, Fitness, Injury|

A healthy team is a happy team - and financially stable. That is to say, athletes don't want to be missing days on the field or put on the disabled list because of an injury. An injured player not only costs the team money, but also the player. The second leading cause for being placed on the disabled list for field position players is hamstring injuries (6, 9). They are also the fourth leading cause for all players (6, 9). A 2004 study stated during the late-swing phase of the gait cycle, the hamstring muscle group is maximally loaded and [...]

Youth Athletes: Is Their Fatigue Risking an ACL Injury?

By |2020-02-25T13:15:47-05:00February 25th, 2020|Fatigue, Fitness, Injury, Sports|

Whether our youth athletes compete for fun or intend on becoming professionals, we enjoy having them participate in sport activities. Their enjoyment, as well as their safety, are our highest priorities. That being said, there are thousands of anterior cruciate ligament (ACL) injuries every year and most of them are for high school athletes (5). How can this be? A 2005 study (6) found an increased risk for ACL injuries correlated with increased knee valgus. Dynamic knee valgus is when the knee "caves in" due to hip adduction and hip internal rotation. Studies have also related increased risk of dynamic [...]

Overuse in Baseball. How to Catch it Ahead of Time.

By |2020-02-18T11:56:41-05:00February 18th, 2020|Baseball, Fitness, Injury, Overuse, Sports|

An athlete performs their best when their body is at its best. Therefore, protecting the athlete from overuse injury is (or should be) a primary concern in sports. For baseball players, monitoring the arm is a big deal. Baseball players, especially pitchers, can put their arms through the ringer with repetitive and forceful throwing motions. The stress of repeated throwing can cause microtrauma in soft-tissue structures. This puts players at risk for chronic injury (1-4) and excessive stretching of the soft-tissue. Chronic stretching of the anterior capsule and tightening of the posterior capsule can lead to trauma creating instability and [...]

Women Athletics: How Your Sport Affects Your Bone Health

By |2020-02-03T09:29:53-05:00February 3rd, 2020|Baseball, Basketball, Health, Sports, Swimming, Track, Volleyball|

Studies suggest women athletics influences change in bone and body composition (3, 6, 8, 9, 11, 13). Furthermore, these changes may be sport-specific (2-5, 8, 10, 11, 13). Every sport has different approaches to training because each sport has different physical requirements and performance needs (2, 5, 8, 11, 13, 14). Significant differences have been found in total body bone mineral density (BMD) among sports (2). BMD has been associated with sport-specific mechanical loading, bone strain, total body mass and lean mass (1, 3-5, 10, 11, 14). Weight-bearing physical activities, such as sports, are noted to promote bone density (1-3, [...]

Can exercise help women age gracefully?

By |2020-01-24T08:48:53-05:00January 24th, 2020|Fitness, Health, Lifestyle, Wellness|

To age gracefully, a desire many women have. But what exactly is aging? If we go to the science, one key process involved in aging is the shortening of telomeres (1). Telomeres function to protect the ends of our chromosomes. Data has suggested physically inactive people are at risk for accelerated shortening of telomere length (8). Similarly, information from pulse wave velocity (PWV) data suggest a relationship with aerobic activity and age-related health parameters, such as arterial stiffening (2). PWV is the rate at which pressure waves move through vessels. Arterial stiffening is the thickening (or stiffening) of the arterial [...]

Ladies, is CrossFit too much on the body?

By |2020-01-30T14:51:27-05:00January 13th, 2020|Fitness, Health, Lifestyle, Wellness|

CrossFit has become increasingly popular, not only among men but women as well. CrossFit is a high-intensity workout program. In addition to improving body composition, it has been shown to improve cardiovascular function in adults (2). However, the effect CrossFit has on a woman’s pelvic floor is uncertain. Pelvic floor muscles help to control your bladder and bowel. Therefore, it is important to keep your pelvic muscles strong and exercise appropriately. High-intensity exercise, such as CrossFit, can increase your intraabdominal pressure. Intraabdominal pressure (IAP) is the pressure within the abdominal cavity. Experts suggest long-term, elevated IAP can predispose women to [...]

Soft-tissue injections: yay or nay? Part 2

By |2020-01-07T09:01:47-05:00January 7th, 2020|Athletic treatments, Baseball, Basketball, Football, Health, Sports|

Make you sure check out Part 1 of this series for background information! In the previous blog, we discussed costs and benefits of soft-tissue injections – specifically reviewing corticosteroid injections. Here we will discuss costs and benefits of 2 other soft-tissue injections: local anesthetic and Toradol. What are local anesthetics? To refresh, soft-tissue injections interfere with the normal healing process in order to get an athlete to return to play sooner. With local anesthetics, there is disruption to axonal nerve conduction (7, 24). What this does is it allows immediate pain relief for an athlete. There are a variety of [...]

Soft-tissue injections: yay or nay? Part 1

By |2020-01-07T09:02:37-05:00January 6th, 2020|Baseball, Basketball, Football, Sports|

Being an athlete means bumps, bruises and strain on your body. In sports medicine, it is common practice to use soft-tissue injections to help relieve pain and/or inflammation caused by athletic activity. Soft-tissue injections are typically done into or near a muscle, tendon, bursa and/or fascia. Though this practice is widely accepted, there are potential serious side effects – especially in the pre-game setting. (16) Typical muscle injuries found in sports include strains and contusions (16). Contusions can result from blunt trauma (16). For example, a player tackling an opponent. Muscle strains can result from continuous/vigorous muscle contractions. For example, [...]

Sleep Deprivation: Will caffeine get you back on track?

By |2019-12-13T14:48:08-05:00December 13th, 2019|Fatigue, Lifestyle, Sleep, Sports|

Sleep deprivation can be a great concern among athletes. With busy schedules and rigorous training, getting adequate sleep can be difficult. Sleep plays an important part in the recovery and performance of athletes (12). Therefore, it is vital athletes make time to rest. But when sleep is hard to come by many athletes choose to combat their weariness with caffeine. However, are you drinking enough caffeine? How tired are you? Let’s take a look at some of the science: A 2018 study (12), investigated the effect of sleep deprivation and use of caffeine on anaerobic capacity. Anaerobic exercise involves short [...]

Grab and Go Energy: Is RedBull really the key?

By |2019-12-12T12:03:38-05:00December 8th, 2019|Fatigue, Fitness, Health, Lifestyle, Sports, Wellness|

As an athlete, it is important to be focused and perform your best. Many athletes, as well as exercising individuals, have begun integrating a quick pick me up before their event to enhance performance. In fact, according to some research (3) sugar-free energy drinks have become staples to athletes and health buffs who are looking to get an extra boost to edge out their competition. But do these drinks really work? Can an energy drink really make a difference in performance or is it all in our heads? And more importantly, is it safe? Let’s take a quick look at [...]
