In training athletes at AC Flora High School in Columbia, S.C. and Oak Hill Academy in Mouth of Wilson, Va., one of my go-to exercises is the single-leg Romanian deadlift. This exercise targets the hamstrings and glutes, and because it is a single leg movement, it also trains balance and can help eliminate any asymmetries in the body from right leg to left leg. Additionally, when athletes perform the exercise with one dumbbell, it trains the core in anti-rotation.

Many athletes have weak hamstrings and weak glutes. The demands of sports like basketball, soccer, and volleyball place a high emphasis on jumping, quick burst running, and abrupt stopping—and all these movements are very quad dominant. It is vital, especially for these athletes, to target both the hamstrings and glutes when strength training to balance out that strength imbalance. One of the reasons I want my athletes to have strong hamstrings and glutes is because these muscles play a major role in protecting the ACL when landing from a jump and planting and cutting.

The Romanian deadlift (RDL) is a staple in my programs because it trains the posterior chain, a group of muscles on the backside of the body. All athletes should train both the muscles in their backside and frontside.

The single-leg RDL does this—and more, because the hip hinge occurs while standing on one leg. This movement is much more difficult to perform. It is great for athletes as they are on one leg a lot of the time in their sport.

As a first step, athletes should be taught the double legged RDL. They can then progress to the single leg RDL. The cues for the Romanian Deadlift are as follows:

1.       The feet should be about hip width apart.

2.       The knees should be slightly flexed.

3.       As you descend, your back should stay flat and the shoulders should be pulled back.

4.       The hips should hinge and be pushed back as you go down while the knees stay slightly flexed.

5.       The barbell should stay close to the body during the entire movement and should be lowered to just below the knee.

6.       As you bring the bar back to starting position, focus on squeezing the glutes.

The cues for the single-leg RDL are similar to the above, with these two additions:

1.       The rear leg should stay in line with the torso for the entire movement. Lock in the rear leg by squeezing and extending the glute.

2.       Hinge at the hips and feel a stretch in the hamstrings of the leg that you are standing on.

When doing the single-leg RDL for the first time, the athlete should first practice the movement with no weight. When adding weight, I like to use a contra-lateral load. That means the weight is in the opposite hand so the exercise is also working the anti-rotation of the core.

Below is a video that shows the movement in more detail.

Although it is the largest muscle in the body, the gluteus maximus has historically not been a major focus of strength training research.

However, there are a number of electromyography (EMG) studies that help us understand how it can be developed most effectively.

Firstly, gluteus maximus EMG amplitude is reduced during isometric hip extension when the hip is flexed, compared to when it is fully extended.

Therefore, exercises with peak contractions in high degrees of hip flexion (such as squats) are likely to be less effective for strengthening the glutes, compared to exercises with peak contractions close to full hip extension (such as hip thrusts).

Secondly, gluteus maximus EMG amplitude is increased during prone hip extension by greater hip abduction, and by greater hip external rotation.

Taken together, these finding indicate that the gluteus maximus is more strongly activated when it is shortened (full hip extension, abduction, and external rotation) than when it is lengthened.

Thirdly, gluteus maximus EMG amplitude is greater when the knee is flexed to 90 degrees, compared to when the knee is fully extended. This is probably because a straight leg leads to more hamstrings involvement in hip extension.

Therefore, exercises that involve hip extension while the knee is more extended (such as deadlifts) are likely to be less effective for strengthening the glutes, compared to exercises that involve hip extension while the knee is flexed to around 90 degrees (such as hip thrusts).

What do these studies mean?

In summary, it seems likely that the best position for producing maximum tension in the gluteus maximus is full hip extension and 90 degrees of knee flexion. This is where the gluteus maximus muscle is shortest, and also where hamstrings involvement is least.

Unsurprisingly, this is the exact position used for manual muscle strength testing.

In addition, it is the top position of the hip thrust exercise, which probably explains why this lift is so effective for glute training.

Training Multi-Sport Athletes Year-Round

February 5, 2017 by williab83

There are great benefits that come to an athlete that trains appropriately for their sport(s). While playing multiples sports takes up much time, athletes must make time to participate in a principled training program that will help them perform their best and help them stay injury free. The task of putting together a program for training multi-sport athletes year-round is a daunting one. Each sport has different demands and every athlete plays a different combination of sports. In most high school settings you are working with a wide variety of athletes and putting a program in place that will help to prepare each athlete for each of their sports is challenging.

In the video clip below Coach Bryan Glover ,MA,CSCS,SCCS and Director of Performance at Valor Christian School, discusses key principles involved in training multi-sport athletes year-round. Coach Glover’s presentation is just one in a series of 10 that deals with how to train multi-sport athletes year-round. To learn how to gain access to his complete presentation and hundreds of other athletic performance videos, simple click on the link Glazier Vault

The video below has sound, so please make sure your sound is turned on.

Coach Glover believes that your training program should be rooted in what is that you hope to accomplish.

The following is a brief recap of Coach Glover’s Key Principles to consider when designing a year-round training program for multi-sport athletes.

1. Use exercises that are ground based movements – exercises where to force is applied to the ground
2. Use exercises that train multiple joints – get the biggest bang for your buck
3. Train explosively – improve speed, power and acceleration
4. Train all energy systems- utilize good work to rest ratios
5. Progressive overload – allows the athlete to see results and keep progressing
6. Teach perfect technique
7. Law of reversibility -keep them them doing some sort of training. Can’t have breaks or you lose ground.

Strength and Conditioning for Tennis

Katrin Koch, CSCS, is the Director of Strength and Conditioning for Olympic Sports at the University of Georgia.

The University of Georgia boasts one of the premier men’s tennis programs in the country. Last year, it captured its fourth-straight Southeastern Conference Championship and made its 23rd NCAA semifinals appearance. One secret to its success is its work on strength and conditioning.

The squad works out year-round, including during the spring competitive season. We dive right into the spring in-season less than a week after players return from winter break. The focus of our conditioning sessions during this time is agility. Some of the exercises we do are ladders with bands, lane drills, Murray drills, slalom step-throughs, side-steps, call-outs, triangle call-outs, and court-tempo runs. The athletes complete four to six sets of each activity, with one to two minutes of rest in between.

Due to the increased practice volume during the spring in-season, I put a lot of emphasis on athletes’ proper execution of these activities. When the squad conditions following a two-hour practice, I know the players have likely used up most of their glycogen stores and might get sloppy with their form. However, forcing them to do each drill correctly when fatigued helps them become more disciplined, which should pay off during long, grueling matches.

The team lifts twice a week during the spring in-season, and the aim is to maintain the strength gains made in the fall. I usually run the players through a strength exercise supersetted with an explosive movement in the same muscle group to increase their power outputs. Here’s a sample workout week:

Resisted Sprinting

Resisted sprinting is now a fairly common method for improving sprint running performance, especially in team sports athletes. Depending on the type of resistance, the resistive force is exerted on the athlete either vertically (e.g. weighted vest) or horizontally (e.g. weighted sled).

Since many studies have shown that horizontal force production is closely linked to sprinting ability, most coaches use horizontally-directed resistance for resisted sprinting training, normally by weighted sled towing.

When sled towing was first introduced, sprint coaches expressed concerns that if the loads were too heavy, then this would alter sprinting movement patterns during the resisted sprint. And if sprinting movement patterns were altered during the resisted sprint, then this could affect movement patterns during an unresisted sprint performed later.

Loads that reduced sprinting speed by 10% were thought to be fairly safe, as they only changed sprinting technique slightly. However, researchers soon identified that both light and heavy sled load can improve sprinting speed.

In fact, heavy sled towing seems to improve sprinting ability more than light sled towing in athletes!

This is probably because it is only heavy sleds lead to greater horizontal impulses (force x time) compared to unresisted sprinting. Since horizontal force production is linked to sprinting ability, this make sense.

Changes in movement patterns during resisted sprinting probably do not produce adverse effects on movement patterns during an unresisted sprint performed later.

This is logical, since we do not generally get concerned about the negative impact of back squats on vertical jumping performance!

And this is a good analogy, because both jump squats and heavy back squats can improve vertical jump height. And now, research has found that even very heavy sled towing can improve sprinting ability. In fact, it improves sprinting performance by more than unresisted sprinting in athletes.

Taken together, these studies suggest that just like gym-based resistance training, sled towing can be performed with a range of loads from light (reducing sprinting speed by 10%) to very heavy (80% of bodyweight) and that all of these options can improve sprinting performance in athletes of varying abilities.
