Should I Train In-Season?

April 12, 2016
As an athlete, you go through different phases of training in a given year. Some of these phases include offseason, pre-season, in-season and post season. The offseason training volume will consist of 3-6x a week. Once you start practices, but no games are played, pre-season training is 2-4x a week. During the season your training volume will decrease to 1-3x a week.   Post season is a short time period where you do very minimal low intensity training. Now obviously, these general recommendations will vary and depend on a lot of different factors. One take away from this is that there is no point in time of the year where you wake up and do nothing to better yourself as an athlete.   There is always something you can do and it is up to the strength coach to manage your stress levels so that you can perform at a high level. Think of “stress levels” as life stressors, sport stress, sets, reps, and intensity. Season Days A Week Volume Offseason 3-6 High Pre-Season 2-4 Moderate-High In-Season 1-3 Low-Moderate Post-Season 0-2 Low You come to the gym every day during the offseason and bust your butt. You will get faster, stronger, and improve your joint range of motion. If you choose to not exercise at some point, your body will begin to weaken and lose all these training effects. “If you do not train it, you will lose it” As a high school player, you will have long days during the season. You will have less time then you did during the offseason to train. “Like anything in life, if it is important, make time for it” How with this schedule will you get a 45min-1hour training session in 1-3x a week? The answer to that is up to you. School from 7:30-2:30 Practice from 3:00-5:00 Dinner 5:30-6:00 Homework 6:00-7:30 Sleep-11:00 The in-season workouts are bit different than the offseason workouts. My highest priority is placed on feeling good to compete at a high level on the field/court. Induce a training effect with minimal to no soreness on the body Sleep and nutrition are vitally important for recovery Take it day by day to see how you are feeling Shorter training sessions Here are reasons why to train in-season So you do not lose all of the training stimuli you gained during the offseason So your performance does not decrease as the season goes on So you don’t get hurt Some of my in-season modifications for exercises will have less eccentric stress then others. I would always want exercises that will have less eccentric stress. This is chosen to not cause delayed onset muscle soreness. I don’t want an athlete playing their sport with sore legs or arms etc. My goals in season are to keep the athlete as fresh as possible to perform at a high level week in and week out.

Power Training for Lacrosse/Baseball/Softball Players

April 12, 2016
Rotational power is an extremely important training variable in any rotational power sport. Most power exercises are sagittal plane-based movements (forward and backward movements), such as box jumps, hurdle hops and any Olympic lifting variations. These exercises are great and are implemented frequently into training programs at MSI. Power and ground reaction forces need to be trained in other planes and directions. As evident in this study, ground reaction forces toward the catcher are high when throwing a baseball. This direction is frontal/transverse plane power. With baseball, softball and lacrosse being such rotational sports, rotational power is a quality that needs to be trained often. Below I will discuss some rotational power exercises that can be performed after a proper dynamic warm-up and before a strength training session. It’s important to note that in order to train power, the movement of the weight or object needs to be fast in order to produce a high amount of force. If the movement is heavy and slow, high velocity power will not be developed. For the power training below, rest 2-5 minutes between sets, so as to not fatigue the body.   Step Behind Med Ball Scoop Toss (https://www.youtube.com/watch?v=1AJN1SBjoHE) How it is Performed: Use a weight that can be moved or thrown quickly. I normally recommend a 10-12 lb. ball for college/professional athletes, an 8 lb. ball for high school athletes, and a 4-6lb. ball for middle school athletes. Start with the ball down by the hip. Step behind the back leg, and rotate your hip throwing the ball as hard as you possibly can. Think about throwing your belly button to the wall in order to get hip rotation, which is where all your power comes from. Reps and Sets: 3-4sets of 1-3 throws a side.   Dynamic Rotational Landmine Press (https://www.youtube.com/watch?v=bWh-IhZdBEs) How it is Performed: Hold the end of the barbell in one hand, with your feet wider than shoulder width, facing the side. Perform a half squat and quickly press the bar up and rotate through the hips and upper body. Control the bar down with two hands and reset to the starting position. Reps and Sets: 3-4 sets of 1-3 a side   Dynamic Band Rotational Rows (https://www.youtube.com/watch?v=uZbxBaIzNnY) How it is Performed: Grasp the end of the band, shift your weight forward with most of your weight on your front foot with an outstretched arm. Rotate the back hip and row the band across your body like your starting a lawn mower. Reps and Sets: 3-4 sets of 1-4 a side   Lateral In-Place Jumps (https://www.youtube.com/watch?v=PJe5bz3zMxg) How it is Performed: Load a hip by sitting back into the heel and jump laterally as far as you can with good ankle, knee and hip control. Stick the landing and quickly jump back to the other direction, throwing your arms across your body as you jump. This is great for developing power in the frontal plane (side to side power). Reps and Sets: 2-4 sets of 4-6 a leg Give

A Word From The MSI Team

March 7, 2016
As MSI celebrates its 10 year anniversary this year it continues its ascent to the premier destination for athlete training in the Philadelphia region. Focused on empowering athletes to reach their pinnacle over the past seven months MSI has added top level facilities, personnel and programs advancing the training and exposure opportunities for the area’s amateur and professional athletes. This past July, the new MSI Sports Village opened which includes seven turf athletic fields. This new venue provides training and exposure opportunities never before seen in Southeastern PA. MSI recognized the need to enhance its services to accomplish its goal of athlete empowerment and this new complex will play a major role in the days, weeks and months ahead. In addition, several new talented personnel have joined the MSI family to bolster an already talented coaching/training staff, including: Kevin Schneider, the former Director of Bubba Baseball who has helped place hundreds of high school players in college Maggie Kichler, a PSAC softball two-time Coaching Staff of the Year member at West Chester University Todd Rizzo, a 15-year professional baseball player who has trained and coached baseball players throughout the region Ryan Griffith, a former college soccer coach with 12 years of experience Many others In December, we launched the new Discovery Showcase Series across all sports. 52 of the nation’s top high school baseball prospects attended MSI’s Discovery Showcase Series MLK Pro Day under the watchful eye of 65 scouts from all 30 Major League Baseball teams. Some of baseball’s most talented amateur players were showcased including Jason Groome, Alex Krilloff, Brandon Martorano and Tyler Mondile. Representatives from Prep Baseball, Baseball America, ESPN, and the MLB Network were also in attendance. In January, we hosted The Cole Hamels Foundation’s pitching clinic. The former Phillies ace was joined by a number of former pro players to conduct baseball exercises, training, mental conditioning, and more. This event further positioned MSI as the region’s destination for athletic performance. The past several months of change at MSI have left people asking, “What’s next?” As always, we remain focused on our goal of empowering athletes to “Earn the Elite.” The goal of MSI is to be a home for every athlete, and empower them to Earn their Elite. With the ability to run leagues, tournaments, rentals, camps, and clinics both indoors and out, in almost every sport, Maplezone Sports Institute provides an opportunity and experience that is almost impossible to find anywhere else.From a barn with one instructional tunnel, to three facilities, including over 60,000 square feet of indoor space, and a 35-acre outdoor complex, MSI has become a home for all athletes to train and showcase their skills at a complete year round sports facility. Thank you for your continued support and dedication. We’re thrilled to continue moving forward helping athletes achieve their goals!

The Discovery of Tyler Dearden

February 29, 2016
Last January, MSI introduced its new Discovery Showcase Series. These marquee events bring college coaches of all levels to MSI to evaluate and interact with high school athletes looking to take their game to the next level. For all intents and purposes, these showcases are a high school player’s opportunity to “Be Discovered.” And, after the inaugural Discovery Baseball Showcase, one such player reaped the rewards more than most. Tyler Dearden, a 2017 Grad Outfielder from Lumberton, NJ, attended MSI’s Discovery Baseball Showcase at the behest of JR Tolbert, MSI’s Director of Baseball Specialty Events and Showcases. “I knew Tyler had drawn interest from a few schools before the showcase,” Tolbert said. “And with his skillset, coupled with the caliber of schools we had attending the Discovery Showcase, it was a great chance for Ty to get on the radar of a lot of top schools.” Dearden, who entered the Discovery Showcase with 2 scholarship offers on the table, took heed of Tolbert’s advice and took full advantage of his opportunity. Posting impressive speed (6.89 – 60 yard), excellent arm strength (88 MPH), and tremendous bat exit velocity (100 MPH), Dearden stood out and had the attention of every college coach in attendance whenever his turn came up. “I really enjoyed the Discovery Showcase,” said Dearden. “I thought MSI ran a great event with many of the top collegiate programs in attendance. I really enjoyed having the opportunity to hit on the indoor field in front of the coaches. I would say this also benefited me the most,” he added. With his impressive display at the Discovery Baseball Showcase, Dearden drew interest from several of the schools in attendance. “I got lots of interest from many schools and have visits coming up with schools that saw me at this showcase.” Dearden also had high praise for Tolbert, saying, “After the Discovery Showcase, he stayed in contact with me, helping me with the recruiting process. He has been in contact with many schools that were at the showcase . . . He also took the time to make up a video of me hitting to send to these coaches. Can’t thank him enough!” Not only did Dearden draw interest from schools at the Discovery Showcase, he also caught the eye of Kevin Schneider, MSI’s Director of Travel Teams, who was organizing MSI’s MLK Pro Day, a premier showcase that brought 50 of the top high school players in the region to MSI to perform in front of 65 scouts from all 30 Major League Baseball teams. “I actually had no idea about MLK Pro Day until after the Discovery Showcase. Kevin Schneider actually invited me at the Discovery Showcase after he saw me perform. He had never seen me play prior to the Discovery Showcase,” said Dearden. Dearden continued his string of impressive showcase performances at the MLK Pro Day, posting one of the highest exit velocities off of the tee (98 MPH), and displaying the arm strength and speed that


Dalton, my wife and I are really happy with the whole experience we had. We really liked Coach Stumpo and what he was saying. My son was all smiles and talked about his lesson the rest of the night. We are DEFINITELY coming back. I have to tell you that my son seemed invigorated about baseball again.

Chris Sweeney, MSI Parent

We are grateful for the experience that Ethan is getting and appreciate all you and the other coaches do for the kids. You guys are very good with the kids run a great program.

Crissi, MSI Parent

We just wanted to thank you for all your help with Jonathan. Today on Super Bowl Sunday Jonathan verbally committed to the Golden Rams of West Chester. Their coach was very excited about his commitment and sees him as one of his top guys for the next four years. The MuckDawgs program has been a great experience for Jonathan right from day one, verses where we came from. Jonathan has worked hard right from the start when you told him to fill out his jersey. You have given him the tools he needs to be successful on the field and in life. We are very thankful for all your help!

Alan & Gretchen, MSI Parents

Brooke is throwing her change-ups and they are working big time! The girls were way ahead of the pitch. Brooke could not stop smiling!
Nice work coach!

Scott, MSI Parent

Thanks for putting on a great clinic and for the hospitality of Maple Zone.
Max is benefitting greatly. He was very excited to have gotten 2 FO wins using the fish hook technique the other night. It is great stuff. You are turning him into a student of the game and have opened up a new world to him.
Great job and thanks again.

Mark, MSI Parent

I wanted to thank you again for putting on a great winter lacrosse league. This was our first year in your league, and it was the best winter league we have played. We will definitely be participating next year.

Jeff, MSI Parent

Service at Maple Zone scheduling the appointment was excellent. Dan is doing a great job instructing Tim on hitting. Tim is very happy to have Dan as an instructor and we’ll be back again scheduling more appointments with Dan soon. Tim has been going to Maple Zone for several years and we are very happy with the services.

Joe , MSI Parent

The instruction and guidance offered to Michael by Corey during a batting session is truly appreciated. Just to see Michael’s expression when he gets that “ha-ha” moment after Corey improves his swing or stance is priceless. Everyone at MSI is truly wonderful. Please convey my Thank you!

Teresa Eze , MSI Parent

We couldn’t be happier, Rizz is a great instructor!

Tom Gartland, MSI Parent
