Our Backgrounds

• Adam• 9 years experience in Elite Sport Physical Preparation• Responsible for 1st Team fitness at Middlesbrough FC

• Iain Spears. • Specialism in computational biomechanics. • Programming in Fortran, C++ and then C#. • Last 5-6 years spent much time working with gaming technology.

• Routine collection of GPS data during training sessions

• 20 hrs missed recovery time• Some scientific evidence for

recommendations• How to get immediate feedback to

the players• Excel or Progamming• Email, Facebook, Web site, Apps

Rationale : Practitioner’s perspective

Making apps the easy way (Unity3D)

• Apple’s App Store (and later Google Play etc) have revolutionised the gaming industry

• Led to the increased availability of easy-to-use tools for creating mobile technology.

• Basic programming in C# • Floats, arrays, bools, ints • Unity3D• Free !

Uploading the .csv files

Downloading, parsing and merging the .csv files

Feeding Back

Step 1: Uploading the .csv files (AdamsUploader.exe)void aaUploadCurrentFTPFile(string fName){

string Password = "EDP6gx****";string Username = "sportsdavz";string LocalFileName = fName;string ServerFileName = "ftp://ftp.cluster007.ovh.net/www/data/footballConference/" + fName;FileInfo toUpload = new FileInfo(LocalFileName);FtpWebRequest request = (FtpWebRequest)WebRequest.Create(ServerFileName);request.Method = WebRequestMethods.Ftp.UploadFile;request.Credentials = new NetworkCredential(Username, Password);Stream ftpStream = request.GetRequestStream();FileStream file = File.OpenRead(LocalFileName);int length = 2056;byte[] buffer = new byte[length];int bytesRead = 0;do{ bytesRead = file.Read(buffer, 0, length); ftpStream.Write(buffer, 0, bytesRead); }while (bytesRead != 0);file.Close();ftpStream.Close();

}

static void Main(string[] args) { aaUploadCurrentFTPFile("gpsMaster.csv"); Console.WriteLine("Uploaded gpsMaster.csv"); Console.ReadLine(); aaUploadCurrentFTPFile("matchplay.csv"); Console.WriteLine("Uploaded matchplay.csv"); Console.ReadLine(); aaUploadCurrentFTPFile("anthrometrics.csv"); Console.WriteLine("Uploaded anthrometrics.csv"); Console.ReadLine(); }

Step 1: Uploading the .csv files

Step 2: Downloading and parsing the .csv files

void aaParseFileGPS() { Global.stackCountGPS = 1; for (int i = 0; i < Global.wLineCount; i++) { int p = 0; parts = Global.lineString[i].Split(','); Global.sessionCode[Global.stackCountGPS] = parts[p++]; Global.date[Global.stackCountGPS] = parts[p++]; Global.week[Global.stackCountGPS] = parts[p++]; etc,etc , etc Global.pl[Global.stackCountGPS] = parts[p++]; Global.plpermin[Global.stackCountGPS] = parts[p++]; Global.plperslow[Global.stackCountGPS] = parts[p++]; Global.stackCountGPS++; }}

void aaReadInNewPlayer(){ for (int i = 2; i < Global.stackCountAnthro; i++ ) { if (Global.playerName[stackCurrent] == Global.playerNameAnthro[i]) { currentBF = Global.currentBodyFatAnthro_p1[i]; currentBFTarget = Global.targetBodyFatAnthro_p1[i]; currentBFError = Global.currentBodyFatAnthroError_p1[i]; currentDist = Global.gpsVar[0, stackCurrent]; } } for (int i = 2; i < Global.stackCountMatch; i++) { if (Global.playerName[stackCurrent] == Global.playerNameMatch[i]) { currentPlayer = Global.playerNameMatch[i]; currentPlayed = Global.played_p1[i]; currentWillPlay= Global.willPlay_p1[i]; currentDaySinceLastGame = (int)Global.dateSinceLastGame_p1[i].TotalDays; } }}

Step 2: Merging the 3 .csv files

bool carb = protein = compression = false; if (currentBFError < 0 && currentDist > 3500) { carb = true; protein = false;}if (currentBFError > 10 && currentDist > 3500 && currentDist < 5000){ carb = false; protein = true;}if (currentDist > 5000){ carb = true; protein = false;}if (currentDaySinceLastGame == 1 && currentPlayed > 15 && currentWillPlay == 1) { compression = true;}

Step 3: Feeding Back

float dy = 1f*Mathf.Sin(Time.realtimeSinceStartup*10f);currentFeedback = "Hi " + currentPlayer + "," ;if (compression){

currentFeedback += "\r\n" + "Please wear your compression garment to aid recovery";planes[0].position = new Vector3(vComp.x, vComp.y + dy, vComp.z);planes[1].position = new Vector3(vComp.x, vComp.y, vComp.z);planes[0].localScale = new Vector3(Global.rfactor * bigr, Global.rfactor * bigr, Global.rfactor * bigr);

planes[1].localScale = new Vector3(Global.rfactor * littler, Global.rfactor * littler, Global.rfactor * littler);}else{ planes[1].localScale = new Vector3(Global.rfactor * bigr, Global.rfactor * bigr, Global.rfactor * bigr); planes[0].localScale = new Vector3(Global.rfactor * littler, Global.rfactor * littler, Global.rfactor * littler);}currentFeedback += "\r\n" + "Thanks" + "\r\n" + "Adam";textMessage.text = currentFeedback;

Step 3: Feeding Back (compression garment)

What information should we feed back to players?

What evidence can we find to justify the specific details of feedback ?

What should we do if the evidence is not there ?

How best to deliver the feedback ?

Player Feedback (for discussion)
