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

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

February 1, 2017 by

This article was provided by Training and Conditioning

By Katrin Koch
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

By Chris Beardsley

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.

High School Strength and Conditioning

January 24, 2017 by

This article is from Coaches Network

Strength training at the high school level is as challenging as any other. Our sister magazine, Training & Conditioning, held a roundtable discussion with five top high school strength and conditioning coaches—some with experience in NCAA Division I and the NFL—who have found that working with high school athletes is exactly what they want to do. And their focus in the weightroom is on building a foundation of movement.

Here are some of their responses:

How did you end up working at the high school level?

Kevin Vanderbush: I started at Ben Davis High School in Indianapolis fresh out of college 32 years ago. Our school was the first in the area to have a full-time strength and conditioning coach.

Mark Asanovich: I’ve kind of come full circle. I got my start as a strength and conditioning coach in 1986 at Anoka [Minn.] High School. I began the strength training program there, became completely enamored with that aspect of coaching, and went on to pursue a master’s in exercise science at Ohio State University. Eventually, I ended up in the NFL as a strength coach for the Minnesota Vikings, Baltimore Ravens, Tampa Bay Buccaneers, and Jacksonville Jaguars. In 2012, my wife and I decided we wanted the stability afforded by the high school level, and I wound up at Minnetonka [Minn.] High School.

Richard Lansky: I had coached at Miami’s Booker High School in the early ’90s and really enjoyed working with that age group. Prior to coming to Manatee High School in 2010, I owned a performance training facility where I worked with college and professional athletes, but I eventually realized I wanted to get back to the high school level. I love this setting because I’m able to expose athletes and non-athletes alike to strength and conditioning principles they can use their entire lives.

Carol Happ: After working as an Assistant Strength and Conditioning Coach at the University of Minnesota and Ball State University for a combined 10 years, I moved back to the Indianapolis area for family reasons and began working for a local hospital network that provided strength and conditioning services in a variety of settings.

​Darnell Clark: When I was pursuing my master’s degree at Arizona State University, I found myself working in a weightroom three levels under the football stadium—going to work in the early morning when it was dark and returning when it was dark. Recently married and starting a family at the time, that kind of grind wasn’t appealing to me, and I viewed the high school level as a way to find better work-life balance. In 2004, I saw a posting on the NSCA website for my current job at Charlotte [N.C.] Country Day School. The school was two years old with great facilities, and I jumped at the chance to work here. I’ve never looked back.

What is your facility like?

Asanovich: Our 5,200-square-foot weightroom is set up similar to the one I had with the Jaguars in terms of space and equipment. The majority of weightrooms today consist of mostly power racks and benches, but ours is 95 percent machines. The literature says your muscles can’t distinguish what’s providing the resistance—whether you stimulate them with a barbell or a machine, you’ll get roughly the same result. Because we have a lot of younger kids who train in our room after school, and as many as 100 athletes can be in there at once, machines are a safer, better option for us.

Clark: We have about 3,500 square feet with a dumbbell rack at each of our 11 training stations. Each station is self-sufficient. I can put four student-athletes at a station for their workout, and they don’t have to go anywhere else. That really keeps the flow going, which is important for me, because I don’t want athletes standing around.

Vanderbush: Our weightroom is 6,200 square feet, and we can fit 100 kids in there at once. Half the room has upper-body equipment, and half has lower-body equipment. I have an elevated office, so I can keep an eye on the entire room even when I have to work on administrative tasks.

Lansky: The main weightroom is 3,000 square feet and has five combo stations. We have an open area to do glute-ham exercises and one lat pulldown. The rest of our equipment is barbells, bumpers, dumbbells, and boxes. We also recently completed phase one of a new strength and conditioning area for our football and boys’ and girls’ weightlifting teams that is 1,500 square feet with a strip of synthetic turf down the middle.

What’s your training philosophy for high school athletes?

Happ: My programming philosophy is very similar to what I did at the college level. Every athlete starts with the fundamentals, and I keep it pretty basic. After they learn the fundamentals, we might get a little more specialized, but my program is not as sport-specific as when I was in college.

Vanderbush: We know that all high school athletes are coming to us with really limited backgrounds in movement skills and strength. Our goal is to make them better overall athletes and limit the risk of injury.

Clark: I’m really big on training flow and work capacity. So when an athlete comes in, they need to know exactly what to do and how to do it. Every athlete understands the process and what to expect.

Asanovich: It may sound a little silly, but I don’t have one. A philosophy is a system of beliefs, and I choose, instead, to take a science-based approach to resistance training using nothing but the most recent research.

How is your program structured?

Asanovich: Generally, we train the entire body twice a week, and our athletes can come in a third time if they choose. But if they’re busting it out twice a week, that’s usually all they need. In-season, we’ll cut that back to one total-body workout and one upper-body workout each week.

I always tell other strength coaches to look for the irreducible minimum: If you’re training the athletes four times a week, reduce it to three times and see what happens. If you get the same results, why go the extra day? When I first got here, our athletes were training three days a week. I cut it back to two, and our results improved.

Happ: I teach 90-minute strength and conditioning classes at Lawrence North, which is when I implement most of my program. I teach three classes a day, and athletes attend two or three classes each week. I also do supplemental work with them after school. They all do the same program for the most part, but I change up the sets and reps depending on whether they’re in-season or out of season.

Vanderbush: I teach a course called Advanced Weight Training, which is limited to athletes. They train with me five days a week for 35 minutes a day, and we do additional work after school depending on sport coach preferences.

What’s your training philosophy for high school athletes?
Happ: My programming philosophy is very similar to what I did at the college level. Every athlete starts with the fundamentals, and I keep it pretty basic. After they learn the fundamentals, we might get a little more specialized, but my program is not as sport-specific as when I was in college.

Vanderbush: We know that all high school athletes are coming to us with really limited backgrounds in movement skills and strength. Our goal is to make them better overall athletes and limit the risk of injury.

Clark: I’m really big on training flow and work capacity. So when an athlete comes in, they need to know exactly what to do and how to do it. Every athlete understands the process and what to expect.

Asanovich: It may sound a little silly, but I don’t have one. A philosophy is a system of beliefs, and I choose, instead, to take a science-based approach to resistance training using nothing but the most recent research.

What do your workouts entail?

Vanderbush: We do two days a week of upper-body lifting and two days of lower-body lifting. On the fifth day, we do circuit training that includes footwork ladders, medicine ball exercises, and core work. For upper-body workouts, athletes will do a chest exercise, a lat pull, a shoulder press, a bicep, a tricep, low back, and abs.

For lower-body work, I think it’s beneficial to include a triple extension exercise, so we do a hang clean two-thirds of the time and a power clean the other third. In addition, I think front and back squats are important, as well as balance-coordination work that addresses hamstring flexibility and stability. One exercise I really like for this is a single-leg dead lift with a kettlebell on a box.

Happ: My program is almost completely Olympic-based. The athletes start each class with foam rolling, and then progress to agility footwork drills and a dynamic warm-up before proceeding to a full-body workout. I don’t do bodybuilding programs, and I don’t really use machines—it’s all barbells and dumbbells. We do a push and a pull, a squat variation, a glute exercise, core work, and we do explosive work with cleans, snatches, and kettlebells. Each workout finishes with static stretching.

Lansky: The bulk of my workouts center on free weight training—multi-joint, ground-based exercises and Olympic lifts. I have spent a lot of time on the USA Weightlifting Coaching Committee, and I have extensive experience teaching Olympic lifts. We use a bunch of 15-pound bars and plastic plates to teach proper bar mechanical position for Olympic lifts because we won’t load athletes if they have faulty movement patterns. Most kids start with bodyweight exercises, then med balls and light barbells before we start loading them with weight.

Asanovich: What is the most catastrophic injury a kid can suffer in any sport? A cervical spine injury. Since we strength train mainly to help athletes avoid injury, my go-to exercises in the weightroom are neck flexion and neck extension. In addition to building muscle with these movements, athletes are strengthening their connective tissue and increasing bone mineral density in the cassettes of their cervical spine, which leads to a more structurally sound neck. I see building a stronger neck as a critical concussion prevention tool.

How do you accommodate the wide range of ability and developmental levels with high school athletes?

Clark: It’s important to have a solid plan for progression. There are all kinds of ways to modify exercises to get different athletes where they need to be. For example, football is one of the most challenging sports to work with because there are so many skill levels. With teams like that, we group players by ability, which determines what type of workout they’ll do each day.

Vanderbush: I’m big on the idea of peer coaching. Within our structure, I might have a class of 80 kids divided into groups of eight—four of whom may have been in my class before, while the rest are newcomers. I ask the older four to take the younger athletes under their wings. We have them remind the younger athletes about good form and how we record our lifts. As a result, our younger athletes feel like someone is looking out for them, while the veterans learn leadership skills and become better at executing the movements through teaching them.

How do you motivate high school athletes?

Asanovich: Nowadays, the stereotypical strength coach is someone who yells and screams all the time. It’s really sad, because when the rubber hits the road, you motivate young people by forming sincere, unique relationships. You have to make a human connection and gain an athlete’s trust. Once you do that, they’ll do anything you ask.

Lansky: You have to get to know each athlete as a person and learn what makes them tick. Whether it’s wanting to move on to the next level, getting noticed for hard work, or even living up to an older sibling’s legacy, each athlete responds to their own motivational hot button.

Clark: For me, interpersonal relationships are key, and that starts by learning all of the athletes’ names. This doesn’t sound like a big deal, but it is. Going to their games is crucial, too. I love watching our athletes compete, and they appreciate it when they see me in the stands and when I compliment them on their performance the next day.

Happ: Athletes must know they have our full attention when they are working out in the weightroom. This means giving continuous feedback.

I’m also very honest, and athletes appreciate that. I make sure to follow every criticism with something positive. Athletes understand I’m hard on them because I know they have great potential, and I tell them as much. That can be a very powerful thing to hear.

What are the biggest challenges at the high school level?

Asanovich: Ninth graders! It can be tough working around some of their emotional immaturity. Also, there are limitations in terms of staff and budget. At the NFL level, I had a big staff and unlimited resources while working with no more than 90 players—and that was only during the preseason. Here, I’m a staff of one with 500 athletes pulling me in 500 different directions all at the same time.

Clark: For me, meeting the developmental needs of our many multisport athletes is a daily challenge. With all their in-season demands—including club sports—they never have an offseason, which makes it hard for them to progress and make gains in the weightroom. They also don’t have enough recovery opportunities—both physically and mentally—so I try to provide them resources on the importance of proper nutrition and sleep habits.

Vanderbush: It can be frustrating when kids pursue personal training services thinking it will give them a performance boost. In most cases, parents simply want what’s best for their sons or daughters and think that means paying a personal trainer or CrossFit gym to put them through additional workouts. However, those private services often don’t take into account what the athletes are already doing in their school strength program. In the best-case scenario, personal training sessions would complement the high school work, not replace or clash with it, but that’s not what usually happens.

Lansky: It’s frustrating to see our athletes for only a few hours each day because we generally don’t know what they’re doing the rest of the time. For example, a lot of our athletes get their only food for the day through the school’s free breakfast and lunch programs, which makes emphasizing the importance of nutrition difficult. To combat that, we started a program here that lets us give our athletes post-workout nutrition like peanut butter and jelly sandwiches and chocolate milk.

What is your advice for coaches who are new to the high school level?

Lansky: You have to be willing to put in the time and wear a lot of hats—especially in the beginning. Then, I would recommend finding resources that can assist your program. Maybe a parent of an athlete has a nutrition background, or another works at a grocery store that can donate day-old bread for post-workout peanut butter and jelly sandwiches. You can also call a nearby college or local fitness facility and see if they’d be interested in donating older weight equipment. You won’t know until you ask.

Also, it’s important to keep things simple with your training. You can have a very basic program, but your athletes will improve if they consistently do it with 100 percent intensity and effort. The reverse is also true: You can have the greatest program, but it won’t have much of an effect if your kids won’t buy in.

Vanderbush: High school strength coaches have to educate all of their constituents on what they bring to the table. They have to meet with every sport coach and show them how they can help their athletes develop and get better. This also means letting parents know how their child will benefit from being part of your program, as well as meeting with your administrators. Every time I get a new principal or athletic director, I make sure I share my thoughts, goals, and previous successes with them.

Happ: No matter what level you work at, it’s important to watch and learn from other strength coaches. And don’t be afraid to ask questions. I am still reading, learning, absorbing, and having “a-ha” moments when I watch other coaches. Sometimes young people in the profession think they know everything, but you have to be willing to take a step back and be open-minded. There are a lot of different ways to arrive at a destination.
