Risk factors for cranial cruciate ligament rupture in dogs participating in canine agility

Background Cranial cruciate ligament rupture (CCLR) is one of the most common causes of pelvic limb lameness in dogs. Risk factors for CCLR include breed (especially large and giant breeds), body weight, gender and spay/neuter status, and age. Few studies have evaluated physical activity and fitness indicators, however, as risk factors for disease. This study used an online questionnaire distributed primarily via social media to assess risk factors for CCLR in dogs actively engaged in agility training or competition to determine demographic and physical activity factors associated with rupture. Results Data from 260 dogs with CCLR were compared to similar data from 1006 dogs without CCLR. All dogs were actively training or competing in agility at the time of CCLR or the time of data submission, respectively. Physical characteristics associated with increased risk of CCLR included younger age, spayed female sex, greater body weight, and greater weight to height ratio. Agility activities associated with increased odds ratios included competition in events sponsored by the North American Dog Agility Council (NADAC), competing at novice and intermediate levels, and competing in fewer than 10 events/year. Odds ratios were lower in dogs that competed in events sponsored by United Kingdom Agility International (UKI). Other activities associated with increased odds ratio for CCLR included involvement in flyball activities and short walks or runs over hilly or flat terrain on a weekly basis. Activities associated with decreased odds ratio included involvement in dock diving, barn hunt, nosework, or lure coursing/racing activities and participation in core balance and strength exercises at least weekly. Conclusions These results are consistent with previous studies demonstrating that body weight and spay/neuter status are risk factors for CCLR in dogs. This is the first report to demonstrate that risk of CCLR in agility dogs is decreased in dogs that engage in regular core strengthening exercises, compete more frequently, compete at higher levels, and compete in more athletically challenging venues.

EFFECT OF THE ISOMETRIC -ISOTONIC EXERCISE ON LIGAMENTS RUPTURE INJURY OF KNEE AND REHABILITATION FOR ATHLETIC

Introduction.Rehabilitation is a program of treatment with some sport exercises targeting the lower body .The aim:of the study is to develop the work of the knee joint after the ligament rupture injury and to rehabilitate itby preparation of the (PTP) proposed training program.Material and Method:The study included 4 injured athletes who were selected from a total of 10 injured.The tools used to measure the angle of flexion and extension of the knee joint before and after rehabilitation are tape measure , anthropometric measurements and squat equipment. Statistical analyses:which used included MEAN, STD, MAX, MIN, MEDIAN to explain the results. Anthropometricis used to measure the (TCUIL) Thigh circumference of upper injured limb and (CBIL) Circumference of bottom injured, Flexion and extension angle of the knee joint and isometric -isotonic exercises with Pre-test –post-test for 4 injures athletes. Results :using the intensity of 30-35% until it reached 95-100% after the end of the training program with 9 -10Kg weights in the first week until 30-35 Kg on squat equipment at the end of the fourth week and it was cured and Anthropometrics of Pre-test was (TCUIL) was 49 and Post-test was 50 cm with increase1cmand the Pre-test of (CBIL) was 34.5 and Post-test 34.7 cm with increase(0.2mm).Conclusions:: The (PTP) developed muscle strength of the femoral muscle groups working on the knee joint after used isometric isotonic exercise
