What you see on TV or on any device playing slow motion sport videos is the result of the editing part. The slow motion effect can be achieved with almost any video editor that has the capability to modify the playing speed of a video. If you want an advanced option, I would go with Adobe Premiere Pro because of its advanced tools. It's a shareware applications but it can be tested for 30 days. Also, Windows Movie Maker has the ability to work with videos and time frames. This is a product bundled with Windows installation and it's available from Start > All Programs > Entertainment section.
In Windows Movie Maker, you need to apply effects in order to achieve the result you want. It can be done from the effects menu.
