Training for Volleyball

[Athletic Lab is the official training center of NC Elite volleyball one of the top volleyball academies in the Southeast] Volleyball is a physically demanding sport, requiring strength, power, agility, and speed; few other sports like it exist (Hadzic et al., 2010). Additionally, volleyball is a sport that requires careful consideration when tasked with enhancing athlete performance. While many clubs are stuck in the old mindset of keeping the status quo, other clubs are shifting their paradigms and pushing the envelope. NC Elite knows that skills and drills alone are simply not effective at bringing about increases in athlete performance. With the help of Athletic Lab, NC Elite has positioned themselves as the premiere volleyball academy in the Southeast. Strength is paramount to volleyball performance, and many examples exist as to why the stronger athlete is always the better athlete. It has been shown that spike velocity in volleyball correlates to strength improvements in the dominant shoulder (Hadzic et al., 2010). Furthermore it is now known that strength training actually has protective effects against "jumper's knee" (Hadzic et al., 2010). In volleyball, jumper's knee is the most common overuse injury (Dervisevic & Hadzic, 2012). Not only will strength training bring about performance gains, it will actually reduce injury rates and overuse injuries through the enhancement of motor-control and joint stability. It is no surprise that the highest jumper makes for the best volleyball athlete. It has been shown that in one game, players execute on average 85 jumps per hour (Riggs & Sheppard, 2009). Of these jumps, blocking accounts for approximately 27% of the jumps (Riggs & Sheppard, 2009). So it is obvious that a stronger athlete is necessary for offenseand defense. The stronger athlete [...]

Heart Rate (HR)-based training: Why it may not work.

HR-based training is about as effective as BMI is for tracking your weight. For those of you that are unfamiliar many of your personal trainers, health care providers, and general practitioners will use BMI as a way to track your body weight. Essentially, it is a height/weight proportion equation, and used by itself it's completely archaic and ridiculous. HR-based training is much the same in this regard--based off of archaic and imperfect data. Currently, there remains no formula that provides an acceptable accurate prediction for HRmax (Roebergs & Landwehr, 2002). Indeed, there is a correlation to HR in response to exercise. As your exercise intensity increases, so too will HR, and this increase mirrors cardiac output (Roebergs & Landweht, 2002). However, researchers and practitioners need a way to quantify this work and to prescribe accurate ranges so that athletes can continue to improve their cardiovascular systems. Currently, this is very difficult to do without a true 'to exhaustion' test. This is where 220-age=HRmax comes in, which was actually preceded by a similar equation, 212-.077(age)=HRmax. Both of these equations are inadequate in terms of predicting your HRmax. In order to further prove this point, a short history lesson is required. Original data on 225 subjects (115 male, 110 females) was used in either a treadmill or cycle ergometer test (the details are not 100% verifiable) and from these tests an equation was derived, 216.6-.84(age)=HRmax (Roebergs & Landweht, 2002). While this equation shows a strong significant correlation (r=.43) the error is considerable (Sxy=11 b/min) not to mention in this study it was found that average decrease in HRmax for women was 12 beats over 21 years and 19 beats in 33 years. What this all means, that, [...]

How to Perform a Proper Pushup

I care about proper, efficient, and safe movements. Some people might consider this overbearing and critical, however it is anything but. My goal as a coach and as a professional is to ensure that my clients and athletes are performing safe and effective training. If they aren't then I am not doing my job. If somebody gets injured on my watch, the fault lies squarely on my shoulders. And if there were one movement that I was to create a PSA about today it would be the push-up. Yes, the standard, everyday, run-of-the-mill push-up. The push-up is arguably one of the most difficult movements to master. Show me one person doing the snatch, clean or squat incorrectly and I will show you 20 people performing the push-up wrong. Why is this? Well, I've spent the past 48 hours researching how to do the push-up correctly and I have found very little empirical data. This could be partly responsible for why so much discrepancy exists. Regardless, we should set a precedent. While there isn't a lot of scientific data depicting what the push-up should look like, it does offer some advice. If we observe the push-up (in it's natural habitat), it's really just an inverted bench (chest) press exercise. The movement pattern is essentially the same. At the start of the bench press the head, shoulders, upper back and glutes are firmly and evenly placed on the bench (Graham, 2003). The grip should be slightly wider than shoulder width; with the hand over the elbow (when looking from the top the hand will reside directly atop the elbow)(Graham, 2003). If we remove the bench, the athlete's body position, with the exception of the legs (since they [...]

Caffeine, Energy Drinks and their Ingredients

If you're like me, then you probably drink a lot of coffee. I require a morning cup in order to function as a human being should. And I'm not alone; the whole world is addicted to this stuff. But I've also noticed a marked increase in the consumption of certain 'energy drinks.' While I don't consume them all that often, I know others do, and I think that they are worth mentioning in this post along with coffee and caffeine beverages. I've begun to question the efficacy of caffeine, energy drinks and their use during resistance training. During aerobic training, caffeine is thought to prolong endurance by promoting fat oxidation through the mobilization of free fatty acids from adipose tissue and intramuscular fat stores (McCormack & Hoffman, 2012). Translation: consume caffeine before aerobic exercise and you may end up utilizing extra fat during the training session, which may in turn reduce overall body fat percentage (over the course of continued bouts). A word of caution though, some sugar-free energy drinks can actually have detrimental effects on your training session. Sillivent et al. (2012) found that consumption of a sugar-free energy drink impaired VO2 max during testing sessions, and in a similar study times to exhaustion were no different in sugar-free energy drink and placebo testing groups. Additionally, researchers believe that performance enhancements may only be realized when energy drinks contain a combination of caffeine and carbohydrates, most notably fructose, as it has been shown to increase VO2 maxes (Sillivent et al., 2012). The rationale is such that the carbohydrate and caffeine mix enhances metabolic function while concurrently providing the body with the added energy from carbohydrates. While caffeine ingestion at moderate doses (3-6mg/kg of body [...]

Examining Overtraining

Recently the question has been asked, what are the signs and symptoms of overtraining? Before we continue onto the signs and symptoms, it's probably important to define and explain what overtraining actually is. While you may never experience this syndrome, it's still important to address the potential threat and take steps to prevent it from occurring. Overtraining syndrome is known by many names. Some may call it burn-out or just refer to the feeling of staleness, heaviness, or low motivation to achieve. As defined by Smith (2004) overtraining occurs when "an athlete is training intensely, but, instead of improving shows a deterioration in performance, even after an extended rest period" (p. 185). Put another way, overtraining is simply the imbalance between adaptation and time allotted for recovery (Sims, 2001). The body needs to be stressed just beyond its comfort zone in order to adapt, this is how we see gains in performance. However, when the stress and frequency outpace recovery the effects can often be deleterious. While overtraining can manifest in many ways (psychological, physiological, biochemical, and immunological) you will probably notice first a change in mood followed by declines in performance (Smith, 2004). As an example, the first signs of overtraining will be psychological in nature; the athlete may go from an outgoing enthusiastic presence to being constantly tired, depressed and uninterested in training or competing (Smith, 2004). While overtraining will affect athletes in different ways, the best thing that you can do is to be aware of its existence. Smith (2004) states that while a general consensus to overtraining does not exist it appears that overtraining is related to an increase in volume and/or intensity of training, or a consistently high volume of [...]

The squat is your foundation

The back squat is a staple at Athletic Lab. You'll find it or one of its variations employed in almost every one of our training sessions. Many people, on first arrival at our facility, are shocked that we teach the deep squat and that our staff are pleased with nothing less than 'parallel'. It is no surprise that our clients are apprehensive when performing the back squat. It is a difficult exercise, and is not as simple as putting weight on one's back and moving the weight up and down in succession. The aim of this article is not to teach the back squat, but rather to discuss two main points of the back squat: technique and safety. Most of you know that we have a highly accredited and knowledgeable staff, but sometimes this is not enough. We certainly understand that, and this is why we constantly provide you with articles designed to pique your interest and challenge your strength and conditioning paradigm. The squat, or back squat as we so eloquently refer to it, is one of our primary, "go to" exercises. Many of you are probably wondering why we teach it. The answer is simple, we use this exercise to enhance performance. Chiu (2009) reminds us that during acceleration, the glutes and the quadriceps supply the majority of force during triple extension and that this triple extension could be significant for an athlete exploding out of a 3-point stance or from blocks, or those in a 'defensive position' (p. 25). As part of a comprehensive program, a highly functional movement such as the squat proves to be an excellent exercise for the athlete or the Crossfit participant. It is the basis, the foundation, [...]

ACL Injuries in Female Athletes

Over half of Athletic Lab's athletes are females. Many participate in sports like volleyball, basketball and soccer that have been linked with very high likelihoods for ACL tears. A large body of literature suggests that gender differences are partially responsible for the high prevalence of ACL injuries in female athletes. It is common knowledge that the female athlete is more susceptible to certain injuries. However, the reasons for why these propensities exist may not be fully known or understood to the athlete, coach or practitioner. The athlete or coach who is constantly keeping up to speed on the latest evidence based research may find themselves perplexed by the number of studies that attempt to determine a causality between genders and ACL injuries. Here we will discuss two studies that provide us with a better understanding of why ACL injuries occur more in females than males. As indicated by Krishnan, Huston, Amendola and Williams (2008) it has been determined that female athletes have a higher incidence of anterior knee pain and non contact anterior cruciate ligament injuries than males (p. 800). Many of us however are left asking how or why this is possible? However, the answer is not as succinct as the question. It has been postulated that altered biomechanics and neuromuscular control play a significant role in the disproportionate incidence of knee joint injuries (Krishnan et al., 2008, p. 800 ). Researchers of this study sought to determine if muscular control of the quadriceps and hamstrings varied in males and females. Although the goal of this study was not to determine causes of ACL injuries, some data was discovered that pertains to this problem. Krishnan et al. (2008) discovered that "females recruit a larger [...]
