BACKGROUND: Very few studies have quantified the degree of fatigue characterized by the decline in the maximal voluntary contraction (MVC) force of the trunk extensors induced by the widely used Sørensen test. OBJECTIVE: Measure the degree of fatigue of the trunk extensor muscles induced by the Sørensen test. METHODS: Eighty young healthy subjects were randomly divided into a control group (CG) and an experimental group (EG), each including 50% of the two genders. The EG performed an isometric MVC of the trunk extensors (pre-fatigue test) followed by the Sørensen test, the latter being immediately followed by another MVC (post-fatigue test). The CG performed only the preand post-fatigue tests without any exertion in between. RESULTS: The comparison of the pre- and post-fatigue tests revealed a significant (P <0.05) decrease in MVC force normalized by body mass (−13%) in the EG, whereas a small increase occurred in the CG (+2.7%, P = 0.001). CONCLUSIONS: This study shows that the Sørensen test performed until failure in a young healthy population results in a reduced ability of the trunk extensor muscles to generate maximal force, and indicates that this test is valid for the assessment of fatigue in trunk extensor muscles.

Some authors claim that occlusal appliances can enhance athletic performance. Therefore this study investigated the influence of dental occlusion on knee muscle strength performance. Twelve healthy female subjects (mean age 24.1 +/- 3.1 years) without temporomandibular joint dysfunction participated in this study. Isokinetic quadriceps and hamstring strength were assessed in relation to three randomized jaw conditions: mouth closed in maximum intercuspidation without splint, mouth closed on a balanced splint which optimized contact over the dental arch, mouth closed on a piece of resin of 1 mm which created an imbalanced occlusion. Tests were performed at 60 degrees /s and 240 degrees /s in concentric and 30 degrees /s in eccentric exertions. Concentric performances did not show any significant difference between the 3 jaw conditions (p > 0.05). By contrast, in the eccentric trials related to quadriceps performance, significant differences (p < 0.05) were observed between the resin condition and the two other modalities (without splint or with a balanced splint). The imbalanced occlusion created by the resin component corresponded to an average decrease of 9% in eccentric peak torque. The eccentric hamstring peak torques also showed a significant difference (p < 0.05) between measurements with splint and with resin (7% decrease when occlusion was imbalanced). In conclusion, among asymptomatic females, artificial imbalanced occlusion induces immediate and significant alteration of knee eccentric muscle performances. Therefore, occlusion examination should be undertaken on a regular and frequent basis for high-level athletes. Moreover, for athletes using mouthguards, muscular performance assessments should be planned with and without the dental protection. [less ▲]

Introduction. Low back pain (LBP) is common among athletes and can be challenging for athletic trainers and therapists. Unfortunately, little is known about symptoms associated with functional lumbar segmental instability (FLSI) in athletes with LBP. Purpose. To determine subjective and objective symptoms associated with FLSI in athletes with LBP. Materials and Methods. We included 24 male athletes (12 soccer players and 12 tennis players) with non specific LBP mean (± standard deviation) pain intensity (0-100 Visual Analogue Scale) and disability (0-24 Roland-Disability questionnaire) scores reaching respectively 35 (±20) and 4 (±3). Athletes were submitted to a standardized anamnesis (including subjective identifiers of FLSI) and a clinical assessment conducted by a manual therapist who explored objective identifiers of FLSI. Results. According to the manual therapist, 12 athletes (6 tennis and 6 soccer players) presented a FLSI. The two groups did not differ regarding pain intensity and disability (P>0.05). However, athletes with FLSI appeared significantly younger than non FLSI athletes (P<0.01). Only three subjective identifiers appeared significantly related to FLSI in soccer and tennis players with LBP: “reports frequent episodes of muscle spasms”, “reports feelings of giving way or back giving out” and “Pain increased with sudden, trivial, or mild movements”. Regarding objective identifiers of FLSI, “positive prone instability test”, “aberrant movement during active and passive trunk flexion-extension“ and “poor lumbopelvic control” were significantly related to FLSI in these athletes. Conclusions. In this preliminary study, 50% of the athletes with LBP presented a FLSI. Some subjective and objective symptoms are significantly related to FLSI in soccer and tennis players. Implications. Athletes with LSI should be targeted for retraining to restore normal movement control. [less ▲]

Relevance: LBP is common among tennis players. More than one third of professional tennis players reported LBP as reason for missing at least one tournament. As impaired lumbar motor functions have been associated with LBP, it appears particularly relevant to assess lumbopelvic movement control in tennis players. Methods: Twenty amateur tennis players (male, 22.9 ± 3.0 years) were included. Subjects were pooled into two groups: 10 players with chronic LBP (mean pain duration: 3.1 ± 2.6 years, pain severity score: 3.5/10 on a pain visual analogue scale) and 10 players without LBP. The Bent Knee Fall Out (BKFO) test was used to assess the players’ ability to control movement of lumbopelvic region. BKFO was performed in supine position and monitored by means of two pressure biofeedback units inflated to 40 mmHg and positioned under the lumbar spine of the participant. The reliability of this test has been previously assessed. Players were instructed to make an active abduction-external rotation movement of the hip (45°) without concomitant lumbopelvic movement of the pelvis and low back. Pressure modification (mmHg) was recorded, each side was assessed. Results: Tennis players with LBP had a worse lumbopelvic movement control than players without LBP both for dominant (9.0 mm Hg vs 3.4 mmHg, P<0.05) as well for the non-dominant side (9.1 mmHg vs 4.6 mmHg, P<0.05). Conclusions: Tennis players with LBP experience similar alterations of motor control as those observed in sedentary people with LBP. However, it remains unclear if these alterations are the cause of the consequence of chronic LBP. Implications: Further prospective studies should assess the cause or effect relationship and should determine whether motor control exercises are effective in tennis players with chronic LBP.
