Explosiveness Training Tips from the NTDP

By Michael Caples, 07/14/15, 2:45PM MDT


Q-and-A with Darryl Nelson, NTDP Strength and Conditioning Coach

USA Hockey: Can you talk about the importance of coaches making sure their athletes are getting into the gym and working out this summer?

Darryl Nelson: Obviously I think it’s a huge component, especially for anybody that is working with teenagers. For kids that have reached their adolescent growth spurt, strength and power are the most trainable traits. They’re kind of getting beyond the windows of trainability for skills and things like that, so at that point in time, anybody that is working with teenagers, their top priority should be trying to make them stronger and faster and more explosive, because that’s where they can improve the most.

USA Hockey: What’s your focus and what should coaches emphasize when it comes to strength and conditioning work?

Nelson: Quality work is the most important thing. What we’re really trying to focus on, what we should be trying to focus on with these players, is making them fast and explosive. A lot of the more popular mainstream workout stuff right now is lots of high reps and lots of fatigue, but that’s not really for athletes that play a team sport. If you want slow and sloppy, then do slow and sloppy training. If you want your team to be fast and explosive and crisp, then all of your training should be fast and explosive and crisp. Quality is paramount. Also, in that same line, if you make somebody really fatigued and you try to use weights, you are significantly increasing your risk of injury. Strength training and fatigue don’t really mix. Fatigue is a byproduct of strength training, so whenever we do our strength training, we always have long rest between sets. We don’t do things in a fashion where the guys become really heavily fatigued. We always want lots of rest, so we’re trying to break up their workout so they’re fresh at the start every set, that they can lift challenging weights every time.

USA Hockey: Explosiveness is a buzzword right now. What are some of your favorite exercises to help a player become more explosive on the ice?

Nelson: Explosive exercises are certainly done in the offseason part of our year. We do lots of jumping and plyometric-type exercises, like Eric Heiden (five-time Olympic gold-medal speed skater) ice skater jump, ladder and diagonal bounding off one foot. Things like box jumps and hurdle jumps and more conventional two-legged plyometrics are still okay. Those are good exercises as well that we use. For our strength training, we use more of the stuff that we’re doing year-round. That would include Olympic-style lifts, single-leg squatting, using various kinds of resistance sprinting, whether it’s like a partner resistance sprint with a band or it’s using some kind of a bobsled or even some on-ice sleds. That’s where we’re getting most of our explosiveness and power. Medicine ball throwing is another great upper-body explosive exercise as well.

USA Hockey: How do you convince athletes that there’s more to it than just building your body to look good at the beach – that there’s a particular way they should be training?

Nelson: In general, we spend time educating the players when they first get here to make them understand the difference between training for performance and whatever popular culture or bodybuilding training might be out there. Those things are really hard for athletes when you talk about the difference between training to be athletic and some other mode of training. I think one thing you can really hit home with teenagers, especially for a teenager, is that they’re really plastic, they’re really moldable, and with the right type of training, you can actually change the ratio of muscle fibers that they have. You can increase, or if you do the wrong type of training, you can decrease the number of motor units they have to possess fast-twitch characteristics. We want to have the highest number of fast-twitch motor units that we can, so if we do the right types of training, we can increase that. We can increase speed and we can also increase our nervous system’s ability to recruit large numbers of motor units in a really short time. That’s what power is. That’s what someone who can shoot a puck with a wrist shot really hard has, or someone who’s really explosive in their first step or their first three steps that’s really fast and it gives them separation. That difference isn’t just the size of their muscles or how much weight they can bench press, that difference is their nervous system and how good their nervous system is at recruiting muscles to work. The timing and sequencing of the motor units contracting also contributes to that.

USA Hockey: What are some of your favorite motivating tactics?

Nelson: I think my favorite form of motivation is education. If the athletes know why they’re doing what they’re doing, they’re going to buy in. If they don’t understand the point, then it’s going to be a really hard sell. You know some coaches will use exercise – push-ups, running, etc. – as a form of punishment or a form of discipline, and in my opinion, if you do that, you’re making the player not want to work out. You’re making working out a negative aspect, so you’re never going to get buy-in at that point. That’s really how we motivate our players, mostly through education, so that they understand why.

USA Hockey: Not all coaches have athletic training backgrounds. What would be some words of advice for them?

Nelson: With technology now, it’s easy to get information; it’s easy to learn. Try to absorb a couple of books from some good strength and conditioning coaches. I really encourage all the coaches out there to view all of the information that the American Development Model has online. Windows of trainability and development, there’s a vast amount of resources available, but I think a lot of coaches aren’t absorbing the information and aren’t exposing themselves to it. Those would be some great places to start.

QUESTIONA player received her second misconduct during a game and was assessed a game misconduct. The player had to skate in front of the opponent's bench to get to the rink exit, and as she did multiple players on the opponent's bench began banging the boards and cheering (essentially taunting her). A bench minor was assessed for unsportsmanlike like conduct to the cheering team. Was this an appropriate unsportsmanlike call?

ANSWER: This behavior by the non-penalized team should be penalized under Rule 601 for “taunting”. If the behavior is only committed by one player, then that player should be penalized. However, if the entire team engages in taunting behavior, and the team coaches make no effort to stop it, then a bench minor penalty would be correct.


QUESTION: During a game there is a scuffle following a check-from-behind into the boards. I reach the scuffle and notice Player A has his hand on the throat of Player B and is pushing him backwards towards the boards. I couldn't tell if he was squeezing the throat or not. What is the correct call? Would this just be a minor for roughing (or something else), or considered a match penalty for attempt to injure?

ANSWER: Considering the USA Hockey Playing Rules mandate a Major plus Game Misconduct for Grabbing the Face-mask, a Match penalty should be assessed to any player who grabs an opponent’s throat. What other rationale could apply to this situation other than the offending player is “attempting to injure” the opponent?


QUESTIONA puck was motionless in the high-slot and an attacking player was skating in from just past the center-line. I (as a goalie) came out to the puck and knocked it away. Just after knocking the puck away, that player and I collided and he fell down. We were moving about the same speed (not super fast). It was pure chest to chest contact. The referee told me that he would assess a penalty if I did that again. What is the USA Hockey's assessment of that interaction?

ANSWERIt's very difficult to answer this question without actually seeing the play. However, due to the fact that strict rules exist that limit player contact with the goalkeeper, it stands to reason that goalkeepers cannot make any reckless contact with players. In the situation you describe, the opposing forward did not have possession of the puck therefore they may not be checked.

However, if the contact was unavoidable, non-injury threatening and incidental from a clean battle for a 50/50 puck then the contact could be deemed “Body Contact” and not against the rules.


QUESTIONTeam A receives a minor plus misconduct, and Team B receives a minor during the same stoppage of play. Since the minors are coincidental, does the misconduct start as soon as the coincidental minors end? Or does it start after two minutes and a whistle?

ANSWER: In any case where a player is assessed a minor plus misconduct, they must serve the entire penalty time in the penalty bench and the misconduct would start immediately once the minor expires.


QUESTIONAttacking player in attacking zone bats the puck towards the net. The goalie decides to cover the puck and play is blown dead. Does this constitute as a “Hand Pass” situation? Do goaltenders count as player that can nullify “hand passes”? Where does the following face-off take place in the above situation?

ANSWERThis situation is not a Hand-Pass since a teammate never touched the puck. The USA Hockey Playing Rules allow a player to bat the puck with the hand, but it may not be played by a teammate immediately following. Since a teammate never touched the puck, there is no Hand-Pass violation.

The face-off would stay inside the attacking end-zone.

THIS WEEK: High-Sticking...serving goalkeeper more.

QUESTIONCan a referee call a High-Sticking penalty against a player if the player's stick hits the referee above the shoulder after the referee drops the puck during a face-off?

ANSWER: Officials cannot penalize accidental stick contact with a player, even if it results in an injury. However, any intentional attempt to injure an official or intentional injury of an official should result in a Match Penalty.


QUESTIONAre neck-guards and mouthpieces mandatory at 10U level?

ANSWER: Under the USA Hockey Youth Playing Rules, mouthpieces and neck-guards are not required equipment at the 10U level. However, leagues and hockey associations are entitled to strengthen equipment rules with approval by the local governing USA Hockey Affiliate. Therefore, we encourage you to check to see if any additional rules apply in your games.


QUESTION: Team A is shorthanded, and Team B is called for a penalty but play continues because Team B has not touched the puck. During this time, Team A scores. Is the penalty called on Team B wiped out as it would be if the teams were at even strength?

ANSWER: In this situation, the Team B penalty (assuming it is a minor) is recorded but not served. Play resumes 5 v. 4.


QUESTIONIn a U10 game, a penalty is assessed to the attacking team. Due ti an officials' error, the face-off is not moved outside the attacking zone. The attacking team scores, and the coach notifies officials of their error. The officials disallow the goal and have ensuing face-off in neutral zone. Is it correct for the goal to be disallowed on the officials error?

ANSWER: Due to the fact that this goal resulted after a face-off location error by the officials, the goal must be allowed.


QUESTIONIf a goalkeeper and an opposing player receive coincident minor penalties does someone have to serve the penalty time for the goalkeeper even though it’s a coincident minor?

ANSWER: The “spirit and intent” of the Goalkeeper Penalty rules (Rule 407) in the USA Hockey Playing Rules is the offending team must lose a player when a goalkeeper commits an infraction. Therefore, despite the fact that the two minors are coincidental and result in immediate substitution (play resumes 5 v. 5), the offending team must still place a substitute player (who must be one of the players on the ice at the time of the infraction) in the penalty bench to return at the first stoppage after two minutes.

QUESTION: Four weeks ago, an official called a penalty against an attacking player for trying to kick the puck out of the crease back to his stick. Now fast forward to this past week, the same situation happens again and both officials state there is no such rule. Which set of officials was correct?

ANSWERProvided the kicking motion does not make contact with the goalkeeper or any opponent, there is no rule in the USA Hockey Playing Rules that prevents a player from kicking the puck.

Rule 627.c in the USA Hockey Playing Rules states,

“Kicking the puck shall be permitted provided the puck is not kicked by an attacking player and entered the goal either directly or after deflecting off any player including the goalkeeper.

However, the puck may not be played by the so called "kick shot," which combines the use of the leg and foot driving the shaft and blade of the stick and producing a very dangerous shot.”


QUESTIONCan a substitute goalie serve a misconduct penalty for another player? For example, a player receives a Spearing penalty (5+GM), can the back-up goalie serve the 5-minute major?

ANSWER: Goalkeepers may not serve penalties under the USA Hockey Playing Rules.


QUESTIONWhat is the rule on mercy rules for 12U level games? If both teams would still like to continue playing in the third period even if one team has a very large lead, is it true that refs are not allowed to continue reffing the game.

ANSWERUSA Hockey does not have any official rules regarding “Mercy Rules”. These are left to the local association or league to determine since they are the ones purchasing the ice slots and managing the operations of the local games.

With that being said, officials are generally assigned to work a complete game regardless of how the game ends (mercy rule, normal game time, forfeit, etc.). Therefore, if teams want to continue playing then all USA Hockey Membership Benefits would be in effect for the complete game, overtime and shootout (and even if they just want to add some extra time to fill the ice slot).


QUESTIONDuring the same shift a single player commits a minor penalty, the other team maintains puck possession and the same player commits another minor penalty. Will play resume "5 v. 4" for four-minutes or "5 v. 3" for two minutes?

ANSWER: Since one player committed two penalties, play would resume "5 vs. 4" for four minutes. If a second player committed a penalty, then play would resume at "5 vs. 3" for two minutes.


QUESTIONPlayer A is pinned up against the side of the net by Player B. The puck is in possession by another player away from the net area. Player B is holding Player A, preventing Player A from escaping to an open ice area. Player A yells out "He's holding me" twice and the ref blows the whistle and proceeds to issue a 10-minute (Misconduct) against Player A. Is a Misconduct call the right call for Player A.

ANSWER: This question is very difficult to answer without seeing the play first hand. However, a player that holds or impedes the progress of an opponent should be penalized for Interference or Holding. Furthermore, any player who displays abusive or derogatory behavior toward an official should be penalized under Rule 601 in the USA Hockey Playing Rules
