Hotspot Response system

Hotspot response is a sensor based fitness training aid suitable for use by all in sport and fitness.  It can be seen as a “game” by young users, used to measure specific aspects of movement by coaches and athletes or simply provide a fun and interactive means of getting moving and improving fitness levels.

Up until now reaction trainers have been static but with Response™ you not only react to the lights but also move to the correct coloured spot on the ground. Activate with hand or foot for truly versatile training. Simply move a dot or two to create a new exercise challenge!

The reaction now has purpose and the movement itself can also be trained.

Whilst static systems do train hand eye co-ordination and reaction, they are limited in relevance in sport by there being no requirement to move.  With Response™ the coloured lights on the base are merely the initiator – it is the following movement that really makes the system so game specific. The coloured spots can be placed in any position or pattern to create many variations of exercise. Have them close together for fast feet and positioning skills or spaced out for movement dynamics and fitness work.

Response – React then Act – Reaction Training How it Was Meant to Be.


The Hotspot Response consists of 4 individually coloured sensors (red, blue, yellow, green) and a base unit.  It has 4 modes of operation, rsp1-4, each with its own functionality and use.  See descriptions in the image below!

Hotspot Response can be used in a wide range of exercises with a whole host of progressions!

Response Exericses

Tactical Movement is a concept that encompasses all of the 4 performance factors and their linkage in particular the limiting effects of each factor on the overall desired outcome and development goal.  It is a holistic approach to player development putting tactical and physical “contextual” competency at the heart fuelling technical and mental development for a rounded a competent tennis player.

The article recently posted entitled Tactical Movement, I admit was a bit on the long side.  It was a few month process to write and it will become central to the Tactical Movement Workshop I am putting together (rough outline is at the bottom of this article should you be interested).  The aim of this post is to bring out the key messages from the article that form the basis of the thinking behind tactical movement.

Limitation Model,

The limitation model states that the tactical intention governs the requirements technically and physically.  Mentally a player must understand the overall process and the application of the techniques (both racket and physical) and also relate the practices and drills to achieving the tactical intention. Since the mind governs the body the understanding and application limits the technical response to the tactical outcome.  underpinning technique is bio mechanical fluidity and within technique comes footwork and movement patterns that are best suited to the tactical intention.

Therefore there is a requirement to develop physical “contextual” competence that includes footwork, movement and body function in conjunction with racket skills with the overall outcome of a tactical desire.  Within coaching, there must be intervention that addresses this area.

360 approach

The 360 approach calls for attention to be paid to developing footwork and movement patterns to support technical and tactical requirements.

Through a complete sequence of execution from initiation to recovery a player’s body function capability is the limiting factor in what is possible.  Professional players do what they do because they can and even they can and will do it better with improved body function.  In a coaching environment, working with developing players, development can occur if the players body can do what it is being asked to and hence the degree at which they can do it increases.

Quality Factor

In striving for the best quality players must be challenged and taught effective means to push the quality factor.  The body limitations, positioning, court coverage, footwork application and recovery will directly impact the quality factor.

Movement and Footwork

Movement and footwork have a tactical relationship with the game and can be developed and progressed.  Players can be taught how to cover court effectively, which footwork steps to apply when and appropriate recovery within situations.  Further more each of these areas can be broken down and developed from static function of the body to dynamic implementation with the ball. As one may break down the forehand cross court and one can also develop the function of the body to aid in this stroke and furthermore consider the ways of reaching the stroke and recovering from it.  Depending on the situation will depend on the requirement of the body, footwork and movement.

What is coming…

In the coming months my aim is to produce and re visit articles that tie this concept up into a deliverable.  From theory to practical exercises and drills to facilitate the development of young players (primarily in U10 mini tennis) but also applicable to older performance players.

A rough outline could be

  • Limitation model
  • Movement concepts (flight, move in balance, fluid move – Action Zone)
  • Emergencies and opportunities (coping and exploiting)
  • Holistic approach, exploiting comfort zones, exploration and growth within coaching
  • Application/handling Pressure (importance of movement and footwork and court coverage)
  • Technique is movement
  • Basic bio-mechanics and functions of the body (general and tennis related)
  • Tactical Movement (Pro analysis, U10 mini tennis)
  • Practical development of Tactical Movement (static/dynamic exercise, footwork development, progressions to ball)


Thanks for reading




The new reaction trainer from hotspot training is in development.

Make it Count with Hotspot Response

This picture is of the base unit that will control the reaction modes. We will be producing coloured spots to correspond with the lights on the base that will be linked uniquely to the base.
Hardware and software are in progress with two intended modes, a reaction mode and a memory speed mode.

Look for more updates and let us know your thoughts on the system.

Make it count!


El sistema “Hotspot” es un instrumento electrónico para entrenamiento de tenistas que da información (feedback) al jugador después de realizar una actividad física.

El sistema consiste en varios sensores táctiles u que pueden situarse en distintas posiciones porque son inalámbricos.

Los jugadores se mueven en una pauta determinada y deben tocar los sensores y un toque se registra en la base de “hotspot”.

El sistema puede programase para medir el tiempo que tarda un jugador en tocar cierto numero de sensores.

Cuantos sensores toca en un tiempo predeterminado las tenistas pueden practicar ejercicios para mejorar su velocidad, agilidad, control motriz y juego de piernas y usando “hotspot” ver sus mejores inmediatamente.

Es mas fácil para los entrenadores concentrarse en observar los movimientos de los jugadores sin tener que estar pendientes de la medición ¡porque “hotspot” lo hace!

Los ejercicios pueden adaptarse para mejorar el movimiento general en la pista o para necesidades individuales especificas

“Hotspot” es un instrumento de uso simple a un precio razonable. ¡Cuenta con ello!

El proceso.

  1. Necesidades y  metas individuales del jugador
  2. Establecimiento de pautas determinadas
  3. ¿Cuáles son los movimientos y técnicas especificas?
  4. Elección de un metador de entrenamiento (velocidad, agilidad, cardiovascular, resistencia)
  5. Mejorar y revisión

Estaré encantado de contestar a sus preguntas con detalle si me contactan por email en mi dirección

The table I am sat is wobbly and to say the least annoying.  I look around for an obvious solution to the problem presented.  I find an old magazine, newspaper or bear mat and I fold the object to a suitable size and place it under the affecting leg.  The table ceases to wobble (for now) and my issue is solved.  Until of course the object deteriorates or the dog chews it or it is removed for some reason and the table reverts back to its old self of wobbliness.  the table has no way of adapting to this situation as it has no mind but it does rock to its so called or perceived centre.  It is just when the table is called upon to be functional the problem presents itself.  The degree of the problem is also a question in that the problem has to become suitably bad before anything is done about it.

The human body can be likened to this situation where there is a compensation or an inhibition but the body can adapt to function (or perceive to function) until one day it decides no.  The body adapts to what the requirements are but the degree at which it can perform the requirements are dependant on how the body currently functions.  If it functions optimally (or as close to as possible) the outcome is arguably good in the required function.  At least it gives the person the best possible chance. 

We could simply replace the table with a new one that doesn’t wobble but in the case of the body this isn’t a solution (apart from in obvious situations and I am not referring to enhanced aesthetics).  

In my work as a tennis coach I have been presented with a child who is struggling to serve due to techniques I have instructed previously.  Not that these techniques are wrong but since I have been with Anatomy In Motion ( I have recognised that there is no wonder the serve is struggling. I have looked at segments of the chain where there are problems and low and behold a foot issue presented itself where the player struggled to absorb weight into the foot when performing the serve and had to constantly reposition the foot to accommodate the action.  This led to mishaps up the chain and hence affected the outcome of the serve.  Attention to improving the foot function allowed a smoother transition of weight into and up through the serve. 

In this case there was no wedge to place under the wobbly table but to educate the body to function optimally (or closer to optimum) to improve the serve.  

There are other situations where I have seen children essentially being prescribed wedges to stop their table wobbling.  What happens when the wedge is moved?  the table wobbles again.  This is the same for the child with a wobble stopping wedge.  Once it is removed the body reverts back.

As a sports coach I am starting believe in a relationship between body and requirement and that the body is our primary tool.  We need allow time to focus on allowing the body to function optimally if it is not and this will help players in their development.  

The question is do we as coaches need to skill up our knowledge in body function, posture, gait etc or do we outsource this to another professional?  I have chosen to delve into this subject as it fascinates me. For me this is a definite requirement of the modern day athlete but who is responsible for it?  

Vertical Jump

Vertical Jump Comparisons

Hotspot Training offers a Vertical Jump Measurement system that operates using the time of flight to calculate the vertical raising of a person’s centre of mass.  The system runs of a 16bit processor allowing a certain degree of accuracy in timing and displays cm:mm.

The system works by using a dot that is configured to be sensitive enough to trigger when the athlete jumps up leaving the dot.  It is then triggered again when the athlete lands back on the dot.


There are some interesting debates about testing and testing equipment and what can be used and compared.

Firstly one must consider the “fair” test criteria probably first studied in school.  This is where testing environments, equipment and methods are repeatable each time a sample is collected.  If they are not the same or the conditions considered acceptable then data cannot be compared.

In the case of the vertical jump there are a few methods and testing units that are available for use.  Each operates in different ways and more interesting are that of the athlete and the method of data acquisition.  For example using the “chalk and wall” method or something like the “Vertec” the athlete looks up aiming for the target and there is no consideration to the landing or where they land.   This method could be considered a pure vertical jump as everything is in the correct plane.  Any shifts in landings will result in lower scores.  When a system involves a landing the athlete will potentially alter the mechanics. In addition the athlete has a host of variables also such as fatigue level, warm up etc that can hinder the tests (example of this later).

The main requirement for a vertical jump system is that it shows progression and improvement that somewhat correlates with current accepted methods.


The Hotspot vertical jump system was tested against two methods (chalk and wall and Vertec) and proven to correlate with progression and give indications within a few cm.  In reality the Hotspot is likely to be the more accurate of the methods due to resolution of measurement in the others.  Also the plane in which the athlete must execute is also likely to be more accurate using the small dot.

In initial tests the athlete was asked to jump using each method separately and the results read within 2cm of each other.

In another test two athletes were asked to use Hotspot and Vertec at the same time.  In both cases the results from Vertec and Hotspot were within approximately 2cm.  These heights were 52cm and 61.2cm

The Hotspot, when tested incrementally with Vertec showed correlation with the progression in height.  Vertec was set at known heights and incremented 10cm each jump and Hotspot results followed this pattern.

In a final test Hotspot was used as a training tool for an athlete to complete 5 jumps at 90% of maximum. This meant the athlete attempted to replicate effort level and jump approximately 52cm.  Hotspot readings for these 5 jumps were with 3cm of this number.

Other findings

In recent data comparison, a tennis player was tested using an electronic jump mat system and the score recorded was 32cm. According to an S&C coach who had worked with the player previously this value was considered low.  In using the Hotspot a week later the player recorded a 42cm jump.  This is a big difference and there is no way of confirming which reading is correct but feeling was that the 42cm jump is more appropriate.


The conclusion to be drawn from all this is that Hotspot is a valid training and testing option for vertical jump.  It can demonstrate improvement and correlates with that of other non-electronic systems.   There can really be no comparison between systems and modalities and whatever testing environment and equipment is chosen must remain consistent.  Hotspot, therefore offers an affordable and useable option for testing vertical jump.
