As a free agent, Senda would be able to join the club outside of the current transfer window, should he impress at Plainmoor.
Senda, 29, began his career at Southampton and was capped by England at youth level, before joining Wycombe Wanderers - making over 300 appearances for the Chairboys.
He has been on the look-out for a new club since leaving Millwall earlier this year, after spending almost two years on the sidelines recovering from a dislocated knee sustained towards the end of the 200-/08 season.
The experienced defender is the third right back to train with the club recently, following brief trials for ex Rushden & Portsmouth youngster Ugo Udoji, and Sunderland-based Neil Simpson.
It’s possibly the one area of the field that Torquay lack options in, and during a long season, competition for places could prove the difference between a promotion push and mid-table obscurity.
Despite Chris Robertson’s consistent form at full back during the Gulls’ flying start to the season, it appears to be an area that Buckle is looking to strengthen as the only other United player with any experience in that postion is midfielder Lee Mansell.
Torquay’s longest serving player has also been at the heart of United’s impressive form of late, and the manager may be reluctant to disrupt another area of the team if Robertson was to fall foul due to injury, suspension or loss of form.
Senda’s experience would be an obvious asset to the Gulls, and provided he has better luck than he has of late - regarding his recent injury problems - he could prove to be a very worthwhile addition to the squad.
Senda played the full 90 minutes as a strong United reserve side triumphed 4-2 against neighbours Exeter City at St James’ Park on Tuesday night.
