First Step Quickness: Method or Myth?
– Derek M. Hansen –
We’ve all heard the claims: “Improve your first-step quickness so that you are lightning fast in your sport!” Is this possible? Is the first step the most important step? If you teach someone to move their feet fast, does that mean their body will follow? These are all important questions that must be answered to determine if a particular training method will yield the best results. In this article, we will explore the different methods employed for improvement of sport speed, as well as assess their relative benefits within a training program.
What are Speed, Agility and Quickness?
An appropriate definition of speed, agility and quickness must be provided before we can determine the best methods of achieving these qualities. I believe that most of the people operating the SAQ (speed, agility, quickness) programs do not know which qualities they are actually training in their athletes. Using Webster’s On-Line Dictionary, we arrive at working definitions of these three words:
Speed
Ve*loc”i*ty\, n.; pl. Velocities. 1. Quickness of motion; swiftness; speed; celerity; rapidity; as, the velocity of wind; the velocity of a planet or comet in its orbit or course; the velocity of a cannon ball; the velocity of light.
Agility
A*gil”i*ty\, n. [F. agili['e], L. agilitas, fr. agilis.] 1. The quality of being agile; the power of moving the limbs quickly and easily; nimbleness; activity; quickness of motion; as, strength and agility of body.
Quickness
Quick”ness\, n. 1. The condition or quality of being quick or living; life. [Obs.] 2. Activity; briskness; especially, rapidity of motion; speed; celerity; as, quickness of wit.
If you examine the above definitions, you will find significant similarities among them. All three definitions have the phrases “rapidity of motion” or “quickness of motion” in common. Using Webster’s definition, we find that these terms are actually redundant when used in combination and provide no distinguishing properties to help the athlete and/or consumer make an educated guess on what to expect in their training. Perhaps using the phrase “Speed, speed and more speed” is just not as marketable and doesn’t make a snappy acronym (three S’s make people think of snakes or air seeping out of a tire, perhaps).
What ultimately occurs is that the marketing gurus take these words and give them new meanings to adapt to the services they are providing which are touted as being comprehensive, multi-faceted and, dare I say, “functional.” “Speed” is put forward as only linear acceleration ability, while “Agility” is apparently the ability to move laterally, backwards, forwards and vertically with uncanny speed. Quickness, then, must mean the ability to move your limbs fast without going anywhere, which is what most of the SAQ drills resemble – lots of work without any useful application. Invariably, the phrase “First-Step Quickness” makes its way into the jargon, somehow implying that it’s the first step that only counts in movement.
We should be able to function in the training world with simply the term “Speed” to describe all of what was identified above. Speed, like the term velocity, can have attributes attached to it, including magnitude, direction and distance. Those in the know will use the term “speed” in this manner referring to short-speed, speed endurance, lateral speed or explosive speed, for example. Until we uniformly adopt this terminology when discussing speed, it will be very difficult to appropriately describe what type of training athletes are actually doing.
For example, I’ll talk to athletes and coaches who claim they are doing speed work. Their workout will consist of numerous repeat 100m runs with a walk back. In reality, no speed work is being done in these types of runs. The recoveries are too short (with the velocities too low) to even deem the work “speed endurance.” They are simply doing a form of special endurance work. However, the runs will still be fast enough to create a risky condition where a muscle pull can occur (i.e. hamstring), particularly during the latter stages of the workout when fatigue is present.
Additionally, you will often hear about fast-footwork being performed in drills that last well beyond 40 seconds in duration, with very short recoveries. In order for an optimized speed adaptation to take effect, the drill should not exceed eight to 15 seconds in duration, and include a significant recovery period for full recovery. Such drills must be monitored with a stopwatch to ensure quality is being maintained over every repetition.
The First Step: Quickness or Quackery
Now that you are thoroughly confused regarding what is speed work and what isn’t, it’s time to get into the individual components of speed. The first step has been analyzed over-and-over again to determine how to make this one stride more effective. Athletes have been told that if they don’t have a quick first step, they will not be competitive in their sport. In reality, the first-step only comprises a very small proportion of an overall performance. It is not the case that the sprinter who gets out of the blocks first does always wins the race. The first step may only cover one meter of distances, meaning that only 1/100th of the race has been completed. Lots of things can happen over 99 meters (or approximately 45 strides). Obviously, the shorter the distance required, the more important the performance of the first step. But quickness is only one part of the first step. There are other qualities that need to be in place to ensure that a good performance is secured. In fact, I would heavily argue that first-step placement is even more important than first-step quickness.
Athletes often think a big, explosive step is the most effective means of beginning locomotion. However, over-committing or over-exerting on a first step is as deadly to an athlete as over-committing on a punch for a boxer or a kick for a martial artist. In the case of a fighter, over-committing on a strike can affect your ability to adequately deliver power on subsequent strikes, as the body is out of position to re-cock the fist or foot. Additionally, over-swinging on a punch or kick can leave a fighter vulnerable to a deadly counter-strike from a well prepared opponent. In the case of a sprinter or any other athlete that is trying to move quickly over the ground, an over-exaggerated first-step can lead to the following problems:
- Forcing the athlete to push their body more upward than forward. This can happen one of two ways: First, if the body is not properly angled for delivery of horizontal force, the athlete’s angle of departure will be too high, leading to a tall posture on the second, third and subsequent steps. Second, if an athlete over-pushes on the first stride, the landing of this first step will typically land too far in front of the athlete’s center of mass, resulting in a pole-vaulting effect and bouncing the athlete upward into a less desirable acceleration posture. Acceleration will be stunted, as an upright posture cannot deliver the hip power required for prolonged acceleration.
- Negatively impacting power delivery and speed in subsequent strides. Running is cyclical and requires an appropriate and efficient distribution of power and stride frequency. Over-emphasis on one single stride, whether it is the first, third or eighth one, can disrupt the effectiveness of the speed run as a whole. Teaching athletes to treat a run as a single, inter-dependent effort of movements – rather than isolating individual strides – will always yield a better result.
- Vulnerability to Direction Changes. If direction change is required, such as for football, soccer and basketball players, an over-exaggerated first step will lead to a reduced ability to change direction, with an extended flight phase occurring before the athlete can get the first step to the ground. This is why we teach these athletes to keep their feet moving in contact with the ground, and not well extended beyond their centers of mass. Over-extension into one direction is an invitation for your opponent to “take you” in the opposite direction.
- Energy management. An overly-ambitious first stride can lead to fatigue in the latter stages of the effort. Athletes must be taught that a quick but controlled effort yields far better results without the danger of running out of gas prematurely.
In other cases, the first step can be almost too quick, in that it lands too far underneath the center of mass, thereby not providing enough vertical force to keep the athlete from falling toward the ground. Inevitably, the athlete will stumble forward awkwardly, with the second stride landing too far in front of the center of mass. As a result, the athlete will be driven upward prematurely, limiting his or her ability to accelerate effectively. This type of striding effort is more common with athletes who are taught to move their feet quickly in a choppy manner, as would be done with a “speed-ladder” device. Drills using a “speed-ladder’ can create artificial stride patterns that do not conform to an athlete’s body dimensions and power delivery capabilities. While beginner athletes will benefit from any kind of work – including tap-dancing through a speed-ladder – advanced athletes must be aware of the biomechanical and physiological demands of their sport.
Those who spend too much effort and investment in training the first step will find that other parts of their movement will be lacking. Even in boxing, the big knock-out punch is set up by a series of other punches and footwork, as well as defensive tactics. If starting speed is what you are looking for, concentrate on body position prior to moving to get the biggest bang for your buck. An analysis of the sprint start out of starting blocks will prove that good start technique is more a function of proper set-up (i.e. block pad placement, hip height, back position) and maximal strength abilities, not how much work is done perfecting the first step. Good coaches never over-emphasize one quality in training. If you come across someone who is expounding the virtues of improving first-step quickness, you will know that you have come face-to-face with a genuine snake-oil salesman.
Recommendations
What we can learn from a close inspection of “first-step quickness” claims is that we must evaluate movements as a whole and not over-emphasize the sum of individual parts. In some cases, isolating sub-components of a movement can help to gain technical mastery that can be extrapolated over the entire movement. However, if a movement is cyclical, there is a heavy interdependence amongst individual strides. Each stride sets up the next stride and a balance exists between all strides. Too much time and energy taken by one stride, negatively impacts the subsequent stride – and so on, and so forth. Control, relaxation and fluidity of motion must take priority above all else. And, total movement speed – your ultimate goal of training – must take precedence over first-step quickness.
Product Review: Casio EX-F1 – The Sports Geek’s Dream Camera
– Derek M. Hansen –
I had the opportunity to try out the recently released high speed digital camera from Casio: The Exilim EX-F1. All I can say is, “Wow!” It does everything that Casio claims it can do and more. If you shoot video or still shots for analyzing sporting performance, this is a camera for you. Even if you can only borrow one for a few days, I highly recommend it.
The Basics
The EX-F1 is a multi-purpose digital still camera and digital video camera. It has an optical zoom capability of 12x (36 to 432mm) that allows you to catch action that is far away. It also has a digital still photo resolution of 6.1 megapixels, which won’t knock anyone’s socks off in this century. However, what sets the EX-F1 apart from the competition is the speed at which it can shoot both still photos and digital video. Still photos can be shot continuously at anywhere from 1 fps to 60 fps. Additionally, video can be shot at frame rates unheard of for consumer based cameras, creating smooth super-slow-motion videos that make your subjects look like they are floating on air. The EX-F1 can also shoot HD videos at 1920 × 1080 resolution. The total package amounts to a credible digital still camera combined with a very flexible digital camcorder. However, the camera does look more like a digital SLR camera than a video camera.
Video Capabilities
The EX-F1 has the ability to shoot high speed video at 300, 600 and 1200 frames per second. This allows you to review the video at super-slow-motion speeds, and provides a smooth, seamless account of human performance. The catch is that the video resolution of these various frame rates is lower than standard video. For example, at 300 fps, the camera captures 512 × 384 pixels, at 600 fps it captures 432 × 192 pixels and at 1200 fps it records at 336 × 96 pixels. I found that for sport analysis, the 300 fps mode captures more than enough information. The resolution is also high enough that you don’t miss out on any detail. You cannot zoom in or out during high speed recording, but there typically isn’t enough time or need to change focal length during quick sporting events. Additionally, you cannot record audio at these high frame rates. Usually the audio sounds like someone moaning underwater during slow motion playback anyways.
The camera comes with some basic software that allows you to play the movie clips on your computer, burn them to DVD and/or upload them to YouTube. To view the videos on your computer, you can use ArcSoft TotalMedia on the supplied CD-ROM. On my computer, the files automatically opened up in QuickTime although the videos were a little bit slower to start. TotalMedia can also be used to burn HD quality movies onto DVD.
For individuals who would like to edit their videos in conventional video editing programs (i.e. Premiere, Pinnacle, MovieMaker, Sony Vegas, etc.) you will have to obtain third party software that can convert the Casio MOV files to a compatible format. I downloaded a program called MPEG Streamclip from Squared 5. MPEG Streamclip allows you to conveniently convert individual files into useable formats. Although it is an extra step in the editing process, the high frame rate video files produced by the EX-F1 make it a worthwhile task.
The only consumer level products that come close to providing the fast frame rate of the Casio are a number of Sony Digital Camcorders that employ what is called Smooth Slow Recording at 240 frames per second. One example of a similarly priced camera is the Sony HDR HC9 which is a mini-DV format High Definition camcorder. The resolution of the 240 fps Sony cameras is similar to that of the 300 fps Casio videos. However, Sony does not provide the option of 600 and 1200 fps, as well as the digital still capabilities of the EX-F1. The only advantage of the Sony HDR HC9 is that it records in HDV format, as opposed to the Casio’s AVCHD format which is much more cumbersome to edit. Sony has hard drive camcorders (HDRSR11 and HDRSR12) with the Smooth Slow Record function, but they also record in AVCHD format. For serious high speed photographers who want high resolution capabilities, you will have to look at more expensive professional cameras such as those offered by Vision Research such as the Phantom HD line which can shoot HD quality video at anywhere from 1 fps to 1000 fps.
Watching a video of sporting movements that has been recorded at 300 frames per second or higher – even if it is something as mundane as running – is breathtaking. It’s as if you are watching a Discovery Channel documentary or a the slow motion clips of football games shot by NFL Films. Using normal 30 fps video slow motion is good, but not even close to 300 fps. At the very high frame rates, the movement is slowed down so much and so precisely that it allows your brain to easily digest the information. When I took video clips of athletes at 300 fps and then showed them the results right away, their response was always along the lines of, “Wow, that is so cool!”
Provided below are some sample video clips that I took using the EX-F1. These clips were converted using MPEG Streamclip, recompressed using Windows MovieMaker and then uploaded to YouTube (even though the camera software has an automatic upload to YouTube function). All of these videos look much better than what you see through YouTube. Unfortunately, I still haven’t figured out how to jack up the resolution for my YouTube uploads. Don’t let the quality of these YouTube videos discourage you from testing out an EX-F1. I will try to follow up this article with more video posts of higher quality.
Sample Video Clips
This video focuses in on the legs during a running drill for a football team. Notice how you can easily watch every aspect of lower limb mechanics: how the foot is landing, where it is landing in relation to the hip, where the stress is being transferred.
This video is of a casual jogger taken from about 50 yards away. Not as dynamic as the football sprint, but still gives you lots of information.
I was in my backyard when I heard a lot of buzzing from some flower pots. Needless to say, I sprang into action and shot this honey bee working over the flowers.
Finally, I had to finish with the requisite slow motion capture of a dog shaking water off its body. Nothing new, but still gives you an idea of the capabilities of the camera.
Digital Still Performance
I’m no expert in the area of digital photography, but I’ve had enough digital cameras in my day. And, I also owned a nice Canon AT-1 35mm SLR when I was a student, shot lots of film and even developed a number of rolls myself. So, when I shot some photos with the EX-F1, I was still pretty impressed. Remember, I would not buy this camera for its digital still performance alone. The 6.1 megapixel photos can be shot in RAW or JPEG format and look quite nice. I won’t post any in this article, as there are many other reviews that handle this aspect of the EX-F1 much better than I could. However, given that the camera had such nice video performance, I was suprised to find that the photos were better than any of my previous digital cameras. The ability to shoot up to 60 frames per second is nice too, although it is a bit of overkill for much of the sporting movements I analyze. Thankfully the camera can shoot pretty much anywhere between 1 and 60 frames per second (10-15 frames per second is usually enough for me), and has a function ring on the lens that can be used to select your frame rate quite easily.

Conclusions
I would definitely buy this camera given my current situation: I’m a father of two small, active children, and I work with athletes in all sorts of sports, where I’m constantly analyzing movement mechanics. The amount of information I get from the high speed video alone is more than worth the money. And, watching your kids jump, bound and run around at 300 frames per second is fantastic. The camera also shoots adequate still photos and normal and high speeds. The 12x zoom lens also allows me to zoom in or out while recording standard or high definition video. The only downsides of the camera are the low light shooting issues, the video format conversion time (AVCHD format) for editing purposes, and the size of the camera, although the camera really isn’t that heavy at all. One figures that the camera has to be quite large to allow for the zoom capabilities and to allow enough light into the lens for high speed shooting.
As with any time you are choosing a camera to buy, it really depends on your needs, your preferences, and how much you are willing to spend. The good thing is that perhaps Casio has now raised the bar for other manufacturers to provide much more advanced features on their digital still cameras and their camcorders.

Get on Your Running Shoes and Go Green!

– Derek M. Hansen –
Elections are looming in both the United States and Canada, and I thought it time to present a more topical post rather than going on and on about something as menial and boring as running. But how can we combine the topic of running (or jogging) and the federal elections without putting more people to sleep? The only option is to blather on about greening up the environment and saving the planet.
With fuel prices going through the roof and SUV’s sitting in car lots with ten-foot pole marks all over them, one wonders why we haven’t heard people (okay, the tree-huggers) calling for “Run to Work Week” in the coming months. The obvious answer is, “Are you nuts!” It’s hard enough to get people out of their cars and onto buses and bikes for their commute to work. Sure taking the bus and navigating a bike through motor vehicle traffic is taking your life into your hands, but hey, saving the planet is a worthwhile cause – isn’t it?
While running to work is not a viable option for 99.9% of the commuter population, putting on your running shoes and doing your workout in the local park or trail system can help to conserve energy and preserve our environment. The amount of people I see using fitness center machines such as bikes, treadmills, steppers and elliptical trainers is staggering. And, pretty much all of these machines require an external power source for operation. It’s bad enough that most of these people are also driving to their local gym or fitness facility to exercise. They also have to drain electrical power to burn a few calories. And, our sources of environmentally friendly electrical power (yes, that quite possibly is an oxymoron) are not keeping pace with demand.
So, what are some environmentally friendly options for exercising in this time of eco-awareness and brutally high fuel costs? Provided below are an array of exercise options that can yield effective results and not kill the planet:
I’m sure there are many other environmentally forms of exercise out there, I just don’t have time to cover all of them. For example, Ultimate Fighting is probably pretty environmentally friendly, as blood is bio-degradable. It’s just not socially friendly. Ultimate Frisbee seems to attract the hippies, so it must be okay too. At least we know it is testosterone sparing.
The point is that we can all make our contribution to improving the environment, even when it comes to exercise. Just make sure to take along your stainless steel water bottle and donate your old running shoes to needy kids in developing parts of the world. Just remember to pull out your unfriendly styrofoam orthotic inserts.
