Aim: Different sports have specific movements which can involve specific kinetic modifications. Therefore these adaptations, if protracted, may lead to muscle and joint damage (Eston, Byrne 2004; Peterson, Renstrom 2002). The purpose of the present research is to investigate morpho-functional asymmetries of lower limbs connected with risk of injury in right-handed basketball players. Methods: 12 right-handed regional level basketball players were recruited (age 21±4 years, height 182±9 cm, weight 76±14 kg, 13±3 years of competitive experience). The following variables were studied: length of lower limbs with a flexometer, hamstring flexibility with a digital goniometer (iPhone 4S, GetMyRom version 1.0.3, USA), bipodalic dynamic balance using a Libra platform (Easy Tech, Borgo San Lorenzo, Firenze), maximal isometric quadriceps strength with dynamometric platforms (Globus Italia, Codognè, Treviso), gait cycle in different running speeds (7, 8, 9, 10 km/h) using Optogait (Microgate Italy, Bolzano). Results: Data show (Wilcoxon test) these following significant variations: - isometric quadriceps strength (P<0.01, -18%: Left 230 kg, Right 191 kg); - bipodalic dynamic balance of lower limbs (Total Area P<0.05, +31%: Left 89°/sec, Right 118°/sec; Outer Area P<0.01, +47%: Left 7°/sec, Right 15°/sec; Outer Time P<0.05, +37%: Left 3.95 sec, Right 5.45 sec; Time of Re-entry P<0.01, +37%: Left 0.74 sec, Right 1.16 sec). Conclusions: A proprioceptive preventive training program should be implemented in order to balance the lower limbs of right-handed basketball players and to avoid possible injury.

Abstract
Aim: Different sports have specific movements which can involve specific kinetic modifications. Therefore these adaptations, if protracted, may lead to muscle and joint damage (Eston, Byrne 2004; Peterson, Renstrom 2002). The purpose of the present research is to investigate morpho-functional asymmetries of lower limbs connected with risk of injury in right-handed basketball players. Methods: 12 right-handed regional level basketball players were recruited (age 21±4 years, height 182±9 cm, weight 76±14 kg, 13±3 years of competitive experience). The following variables were studied: length of lower limbs with a flexometer, hamstring flexibility with a digital goniometer (iPhone 4S, GetMyRom version 1.0.3, USA), bipodalic dynamic balance using a Libra platform (Easy Tech, Borgo San Lorenzo, Firenze), maximal isometric quadriceps strength with dynamometric platforms (Globus Italia, Codognè, Treviso), gait cycle in different running speeds (7, 8, 9, 10 km/h) using Optogait (Microgate Italy, Bolzano). Results: Data show (Wilcoxon test) these following significant variations: - isometric quadriceps strength (P<0.01, -18%: Left 230 kg, Right 191 kg); - bipodalic dynamic balance of lower limbs (Total Area P<0.05, +31%: Left 89°/sec, Right 118°/sec; Outer Area P<0.01, +47%: Left 7°/sec, Right 15°/sec; Outer Time P<0.05, +37%: Left 3.95 sec, Right 5.45 sec; Time of Re-entry P<0.01, +37%: Left 0.74 sec, Right 1.16 sec). Conclusions: A proprioceptive preventive training program should be implemented in order to balance the lower limbs of right-handed basketball players and to avoid possible injury.
