Steal This Drill: Grab a Bench for Better Depth

Again, much gratitude is due to Roy Coopersmith for suggesting the following drill. The purpose of this drill is to improve the depth of one's groundstrokes. One way to do this would be to place a broomstick or PVC pipe through, or, conversely, an Airzone Training System over the net. This forces the player to aim considerably higher than the net thereby increasing the player's margin for error in a match.

However, one problem with relying strictly on an above-the-net device is that players tend to limit their shots to height while not improving their depth. In other words, there's a risk that the player will develop high, loopy shots that bounce mid-court (and can be easy sitters for the opponent). The goal for a tennis player is to hit high over the net but to also have deep, penetrating shots that put the opponent in a defensive position (or, at least, a position from which they are unable to hurt you). As previously discussed, one of the main strategies in tennis is to hit the ball deep in order to (a) put the opponent in a defensive position and force him to expend his own energy to give pace to the ball; (b) cut down on the angles that he may be able to hit; and (c) put yurself in the best position to control time and space. In order to develop depth, it's not enough to hit the ball high or hard; it's finding the middle ground where you're staying away from the net but also hitting just inside the baseline.

You can develop this comfort zone my placing a plastic bench (chair or pee-wee tennis net) on or around the practice partner's service line (or on both sides of the court - for both players to practice). The players will then rally (baseline points) OVER the net as well as the bench. This simple exercise forces the players to hit not only high, but penetrating shots that explode off the court. Once the players master this drill, they can alternate rallies where one player hits 5-10 deep shots and then a short angle. Doing so would teach the players how to be flexible with their thinking: push the opponent deep; then yank her side-to-side with sharp angles. 

Training the Body's 3 Energy Systems

I would like to thank Ray Brown (Director of EASI Academy, Houston, TX; contributor to MidAtlantic Match Point, TennisONE, Procompare tennis and Tennis World USA) for piquing our interest in this topic. On an unrelated forum, Mr. Brown challenged contributors to (1) identify the three energy systems of the human body; (2) determine how each system is best suited for a particular tennis strategy; and (3) outline how to efficiently develop each system.

From our research - and bearing in mind that we discarded our lab coats, protractors and test tubes exactly 0.34 seconds after receiving our respective college diplomas - it appears that the three types of energy systems are as follows: ATP-PC; Glycolytic; and Oxidative.

1. ATP-PC: anaerobic energy system that utilizes ATP (as in Adenosine Triphosphate - a nucleotide that performs many essential roles in the cell including providing energy for cellular activities) to create energy. When this process takes place, ATP is broken down into ADP (Adenosine Diphosphate). The body then has to add phosphocreatine (PC) to the ADP in order to form ATP. This chemical energy source is used by living things almost like a battery - for short bursts of high-intensity work lasting approximately 10 seconds or less; think "maxing" in the weight room. In terms of tennis, this is the system that would support your body's energy needs in high intensity points of short duration: e.g., serve and volleys.

2. Glycolytic (Lactic Acid System): this system utilizes glucose (or carbohydrates stored in the muscle) to create ATP for energy. In this system, six-carbon sugars are split to three-carbon compounds with subsequent release of energy. Glycolysis can happen under anaerobic and aerobic conditions. However, because of the duration needed to break down glucose to form lactic or pyruvic acid (10 separate reactions), it is the system used for relatively short periods of high-intensity work lasting only a few minutes - think a set of circuit training. After a few minutes of work, the body accumulates lactic acid to the point where pain and fatigue (accumulation of acid breaks down the muscle) will begin to affect performance. For tennis players, this is the main source of eneregy. Most points are won and lost in bursts lasting anywhere between 30 seconds to 1 minute (more than ATP-PC but less than Oxidative). With a short rest break, the work will have to be repeated.

3. Oxidative (Aerobic System): this is an aerobic energy system where the body utilizes carbohydrates, fats and proteins to generate ATP for energy. This a complex system which relies on the circulatory system to supply oxygen. Although slow to kick in, it is the primary system used for long-term, low-to-moderate-intensity work lasting more than just a few minutes - think marathon runners. Although it's unlikely that tennis players will be called to rely on this system as a primary source of energy, it is foreseeable that under some circumstances - extremely long matches which rely mostly on endurance (extremely long points) rather than power - it may be a factor. However, we are "endurance animals" and, therefore, we should focus more on things at which we do not excel than building up the support system that we already master, The limits of endurance exercise, Basic Res. Cardiol. 2006 Sep. ("A skeletal design which favours running and walking, including the greatest ratio of leg length to body weight of any mammal; the ability to sweat and so to exercise vigorously in the heat; and greater endurance than all land mammals other than the Alaskan Husky, indicates that humans evolved as endurance animals").

A good training system will focus on developing each energy system. The first system is trained by including lots of short but high intensity drills into the practice. Think, for example, serving at 95%-100% of your speed and bolting towards the net in a quick sprint. Or, alternatively, perform 2-3 shot combos at maximum power and intensity. The player performs a lot of these sets but is given adequate time to recover. Some nutritionists would advise the post-workout ingestion of creatine (natural or supplement) along with simple sugars to rebuild the body's PC storages. The second system would be trained by performing repetitive, medium-intensity drills, lasting anywhere from 1 minute to 3 minutes. Utilize figure-8s, corners or side-to-sides (now you know why pros favor this drill). Again, adequate rest is given between sets in order to allow the body to recover. You rebuild this system by ingesting protein (amino acid leucine), glutamine, Vitamin C and water. To train the third system, you want to include drills that last anywhere from 20-40 minutes (depending on the level of the player). Although these drills would be of relatively low physical intensity (e.g. cross-courts, down-the-lines), the players should "suck in" sufficient oxygen in order for the oxidative process to commence. Players should look for slightly elevated but rhythmic breathing to ensure that enough oxygen is being ingested. If possible, coaches should develop training regimens where the boundaries of all three systems are being pushed beyond the player's comfort zones.

Nevertheless, since most points are played within the ATP-PC and Glycolytic range, a competitive player who has mastered the basics of the various strokes should spend the majority of his practices trying to improve those 2 systems. Unfortunately, a lot of players spend an inordinate amount of time working on stationary drills (which may kickstart the aerobic energy system) that have no effect on increasing the threshold of the two main energy systems for this type of an activity.

Steal This Drill: The Rainbow Drill

It is said that great minds think alike. As evidenced by the following drill, the same thing can be said about lesser minds as well (just kidding). The following drill is a collaboration between CAtennis.com, Karl Rosenstock and Roy Coopersmith. As it happened, and out of pure coincidence, the three parties discussed covering the following drill on exactly the same date. 

Here's a little background on our co-conspirators:

Karl Rosenstock: Karl is currently the official tennis X-mo cam videographer for USC Tennis and a Contributing Editor for CAtennis.com where he provides video content and articles. These days, Karl is most well known as the tennis slow mo guy insofar as he provides X-Mo cam high speed videography for tennis coaching and keepsake purposes for college tennis, tennis clubs and tennis tournaments. Karl has been a USPTA tennis teaching professional and professional television producer. He has specialties in producing, multi camera studio production and directing, lighting design and studio and remote camera operation. For more information regarding his services, please contact Karl at 415-794-5250.

Roy Coopersmith: Roy is currently the Tennis Director at Pine Bluff Country Club in Pine Bluff, Arkansas. With a tennis career spanning over 4 decades, Roy has done it all and seen it all. He was an accomplished professional, college, open as well as senior player (#6 in Germany in U40s) and, as a coach, he has had the opportunity to coach an impressive list of players including: Philipp Kohlschreiber, Lisa Raymond, Tom Shimada, Jelena Jankovic, Jamea Jackson, Christian Weiss, Toma Walter, Maja Palaversic,  Christina Singer, Kim Couts, Roko Karanusic, Helena Vildova, Nguyen Hoang (2009 Orange Bowl Champion), Josip Mesin, etc. Currently, however, his main focus is on developing the game of his daughter - Niki Coopersmith. Nevertheless, if going to the next level is your goal, Roy has the technical, tactical, mental and physical expertise to assist you.

Rainbow Drill:

Here, at CAtennis.com, we are huge fans of situational-based practice. We feel that if the players have experienced certain pressure situations in practice they will be able to relax and think more clearly in the heat of battle. In the Rainbow Drill, one of the players starts with his racket on the net chord and the other is on the baseline. The coach (or the baseline player) feeds a deep lob over the net-player. The lob should bounce somewhere close to the baseline (even slightly outside of the lines). The net player chases it down and either hits a baseline overhead or a groundstroke. The baseline player must let this ball bounce and the point starts immediately (i.e., if the net player misses the "feed" he loses the point). This drill is not only a fun variation on the ol' baseline game, but it also teaches the players how to hit overheads from less than optimal positions and, also, how to regain the advantage after having lost it. This is particularly important for juniors and female players bacause they may lack the put-away ability from the net. That is, sometimes players get to the net but fail to capitalize on the situation and are forced to "restart" the point if the opponent comes up with a decent lob. This drill will, hopefully, teach the players that losing the upper hand mid-point is not the end of the world. One can regain the advantage with a well placed shot...a shot that must be practiced and mastered. 

Whatever Problems You May Have, They Have Their Own Problems Too

Whatever problems you may have, just remember they have their own problems too. This is very practical advice that is very easy to forget in the heat of the battle. Reading this article, unemotional and clear headed, this makes perfect logical sense. Only problem is it is very hard to remember when you need it. Everyone needs to be reminded from time to time that it is easy to forget the task at hand (to win the match) instead of intensifying all your time and energy on your own problems (technique, feeling the ball, dogmatic strategies, etc). Tennis is never static, the elements are always changing. Your opponent is confronting their own demons as the match unfolds, you may not know exactly what those issues are, but they are lurking underneath the surface. If you are paying attention, good things can happen.

The most efficient players mentally play tennis from a 3rd person point of view as if they are observing the match from the stands. As the match unfolds, they take notes on all the jabs and body blows delivered and recieved. They see with clarity how their opponent is boiling inside, frosting at the mouth when things don't go their way. They see with crystal vision how their opponent plays 30-all points. They see how their opponent can't keep their cookies together when they get a break of serve. Sometimes these little cues and nuances can tip the match in your favor and increase your odds of winning.

Imagine the following scenario. You are down 2-0 to an evenly matched player who you have never played before. I say evenly matched because you have done your research and you notice you have similar wins and losses in comparison. The stakes are high and pride is on the line, you both desperately want to win. Your opponent serves at 2-0 and easily holds for a 3-0 lead.

FREEZE

Most players confronted with a 3-0 deficit hit the panic button. Uh oh, change strategy. Go for broke. Serve and volley. Pace around the court in-between points. Panic, panic, panic. Drastic measures have to be taken.

REWIND

It is only one break of serve. You were nervous to start the match giving them a handful of unforced errors. Lets settle down and make them hit some balls. "Aha, whatever problems you have, they have their own problems too!" This wonderful piece of practical advice pops into your head and your blood pressure goes down. You realize the match is not slipping out of your hands, but it is closely within reach. You buckle down and get back to work.

OTHER SIDE OF NET

Your opponent who just held for the 3-0 lead is overthinking it. "What a great start! Shoot, I don't know if I can keep this up. I'm playing awfully good, almost too good to be true. What if he starts to make some returns? He doesn't realize I don't like long rallies. I hope he keeps missing."

So if you remain calm and practical, just remember, whatever problems you may have, they have their own problems too. Sometimes your opponent is willing to lose the match if you give him a chance to choke. Better players don't crack til deeper in the match, your job is to hang around and find their breaking point. You got nothing better to do, so just keep hanging around.
