Effect of a Mediterranean-style diet on the exercise performance and lactate elimination on adolescent athletes.

BACKGROUND/OBJECTIVES: Mediterranean diet is an environmentally friendly and healthy diet model. The diet offers many vegetables, fruits, nuts, and olive oil to consumers. In addition, it provides moderate amounts of fish and chicken, smaller quantities of dairy products, red meat, and processed meat. The Mediterranean diet has a high anti-inflammatory and antioxidant content, and it causes many physiological changes that can provide a physical performance advantage. This study examined the effects of a 15-day menu, which was planned using foods with a low acid load within the Mediterranean diet rules, on the exercise performance, lactate elimination, anthropometric measurements, and body composition. SUBJECTS/METHODS: Fifteen professional male athletes between the ages of 13 and 18, who were engaged in ski running, were included in the experimental study. Dietary intervention was applied for 15 days. The athlete performances were evaluated by applying the vertical jump test, hand grip strength, 20 meters shuttle run test, and Borg fatigue scale. After the shuttle run test (every 3 min for 30 min), blood was drawn from the finger, and the lactate elimination time was calculated. Performance and lactate measurements, body analysis, and anthropometric measurements were taken before and after dietary intervention. RESULTS: The vertical jump height and hand grip strength increased after the intervention (P < 0.05). The test duration, total distance, the number of shuttles, and maximum oxygen consumption parameters of the shuttle run test increased (P < 0.05). After the intervention, the athletes' perceived fatigue scores decreased in several stages of the shuttle run test (P < 0.05). The lactate elimination time and athlete's body composition were similar in repeated measurements (P > 0.05). In the last measurements, the upper middle arm circumference decreased while the height of the athletes increased (P < 0.05). CONCLUSIONS: These results show that the Mediterranean diet is a safe and feasible dietary approach for aerobic performance and strength increase.

The Effects of Exercise Prescription on Aerobic Performance and Quality of Life During the Course of Lymphoma Chemotherapy: Results of a Prospective Controlled Study.

BACKGROUND AND AIM: This study is designed to investigate the physical, psychological and quality of life (QoL) effects of a 16 week supervised and structured intensive aerobic and strength training during the first line chemotherapy of lymphomas. PATIENTS AND METHODS: This pre-post study with two groups enrolled ≥18 years of age lymphoma patients scheduled for the first line chemotherapy. Eligible patients were assigned upon patients' preference either to control group (Group C) involving simple counselling, or intervention group (Group I) involving supervised intensive training. Baseline, interim and final evaluations were performed per protocol. Repeated measures analysis of variance was used to investigate the effect of intervention. RESULTS: The mean age of 47 enrolled patients was 44 [standard deviation (SD) ± 17] and 27 (57.4%) of them were male. Patients in Group C (n = 19) and Group I (n = 28) had similar baseline characteristics. Tmax was significantly higher in Group I (P = .03) without a significant change during the study course (P = .98). Significant increases were observed in the power of some muscle groups, irrespective of the intervention type. The mean adherence rates were 83.0% (SD ± 22.0) and 54.0% (SD ± 23.0); the discontinuation rates were 10.7% (n = 3) and 42.9% (n = 12), at interim and final evaluations, respectively. CONCLUSION: Both supervised and structured schemes and simple counselling, prevent further muscle wasting and lead to modest improvements in aerobic performance and muscle strength during lymphoma chemotherapy. These results do not translate into a significant improvement in QoL measures. Non-adherence and discontinuation are important issues to be solved.

Radiological maturation and clinical results of double-bundle and single-bundle anterior cruciate ligament reconstruction. A 5-year prospective case-controlled trial.

INTRODUCTION: The aim of the study was to make a prospective comparison of the radiological and clinical outcomes of patients undergoing single-bundle and double-bundle anterior cruciate ligament (ACL) reconstruction. METHOD: This prospective, case-controlled study included 65 patients, separated into 2 groups as 33 patients undergoing single bundle (SB), and 32 patients undergoing double bundle (DB) ACL reconstruction. The patients were evaluated clinically using the International Knee Documentation Committee (IKDC) and the Lysholm knee scores. Stability was evaluated with the KT-1000 Arthrometer Measurement, the Lachman and pivot shift tests. Magnetic resonance images (MRI) at 1 and 5 years postoperatively were evaluated by a musculoskeletal radiologist. All the operations were performed by a single surgeon and the clinical evaluations were made by an independent researcher. RESULTS: Evaluation was made of a total of 53 patients (SB: 28, DB: 25). No statistically significant difference was determined between the groups regarding the postoperative IKDC and Lysholm scores. The pivot shift tests were negative in the DB group and positive in two patients of the SB group. The Lachman test was negative in all the patients. No significant difference was determined between the groups. No statistically significant difference was determined between the two groups in respect of the arthrometer measurements. In the SB group, revision surgery was performed in two patients due to graft failure. No graft failure findings were determined in the DB group, and no statistically significant difference was determined between the groups in respect of graft failure. On the MRIs taken at 1 year postoperatively, the ACL was seen to be hyperintense in 16 patients in the DB group and 6 patients in the SB group (p = 0.004). On the 5-year MRIs, ACL hypointensity could not be seen in three patients of the SB group and two of the DB group, with no difference determined between the groups (p > 0.05). CONCLUSION: In the 5-year follow-up period, no difference was determined between patients undergoing SB ACL reconstruction and those undergoing DB ACL reconstruction regarding clinical scores, knee stability, and MRI findings, but graft maturation occurs later the patients undergoing DB reconstruction.

A Surgical Algorithm According to Pivot-Shift Grade in Patients With ACL Injury: A Prospective Clinical and Radiological Evaluation.

BACKGROUND: Some patients have a positive pivot-shift finding and rotational instability after anterior cruciate ligament (ACL) reconstruction (ACLR). Three major pathologies known to affect the pivot-shift examination include ACL tear, anterolateral ligament injury, and loss of posterior lateral meniscus root function. PURPOSE: To describe a surgical algorithm determining indications for lateral extra-articular tenodesis (LET) based on intraoperative pivot-shift examination to prevent postoperative pivot shift and rotational instability and to evaluate the 2-year clinical and functional outcomes. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: The study included 47 consecutive patients (39 men and 8 women) who underwent operative treatment for ACL injury between 2016 and 2017. Pivot-shift examination was performed under anesthesia, and the pivot shift was graded as grade 1 (glide), grade 2 (clunk), or grade 3 (gross). According to the surgical algorithm, single-bundle ACLR was performed in patients with grade 1 pivot shift. In patients with grade 2 with loss of posterior lateral meniscus root function, concurrent lateral meniscal repair was performed, and in patients with grade 2 with an intact lateral meniscus posterior root, concurrent extra-articular iliotibial band tenodesis was performed. Patients with grade 3 underwent ACLR, lateral meniscal repair, and LET. Clinical and radiographic evaluations were performed. RESULTS: The mean age was 27.2 years (range, 16-56 years). In total, 26 (55.3%) patients were evaluated as having pivot-shift grade 1; 16 (34%) patients, grade 2; and 5 (10.6%) patients, grade 3. A total of 7 (14.9%) patients underwent LET in addition to ACLR. Two of these patients had pivot-shift grade 2, and LET was performed since the lateral meniscus posterior root was intact. In 14 of 16 patients with grade 2, lateral meniscus root disruption was detected, and lateral meniscal repair was performed. One patient was excluded from the further follow-up because of graft failure. At a mean postoperative follow-up of 29 months in 46 patients, the pivot-shift examination was negative in all patients. The mean Lysholm and International Knee Documentation Committee subjective scores were 95.35 ± 4.40 and 82.87 ± 9.36, respectively. Radiographic evidence of osteoarthritis was not detected. CONCLUSION: Only 14.9% of patients needed LET. With proper ACL, lateral meniscal, and anterolateral ligament surgery, it was possible to prevent positive pivot-shift findings postoperatively.

The effects of exercise on mastalgia.

OBJECTIVE: Mastalgia is often ignored by physicians although it is the most common breast-related complaint among women. The effectiveness of exercise therapy for mastalgia is unclear. The aim of this study is to investigate the effects of exercise on mastalgia. METHODS: A randomized controlled trial was conducted with twenty women with complaints of mastalgia fulfilling the inclusion and exclusion criteria. Patients were randomly assigned to the control group and to the exercise group. Sports brassiere, refraining from caffeine- and methylxanthine-containing foods, and simple analgesics were recommended for two groups. In the exercise group, an exercise program was conducted three times a week for 6 weeks. Participants in both groups were evaluated for breast pain and using the Short-Form Health Survey (SF-36) questionnaire before and six weeks after study. Serum cytokine levels were also collected and analyzed. RESULTS: No significant differences were detected with respect to age, body mass index, menopausal status, psychiatric condition, and existence of unexplained pain syndromes between the groups. Total breast pain scores were similar in both groups. The sensory component of breast pain questionnaire and visual analogue scale values significantly improved via exercise in only exercise group (p = 0.012 and p = 0.016). There was no significant difference between groups in serum levels of cytokines. SF-36 subscale scores for general health and social functioning significantly improved in the control group and scores for role physical, bodily pain, and social functioning improved in exercise group. CONCLUSIONS: Based on our preliminary findings, exercise treatment is beneficial for patients with mastalgia and it can be suggested by clinicians.

Cross-cultural adaptation of VISA-P score for patellar tendinopathy in Turkish population.

INTRODUCTION AND PURPOSE: VISA-P questionnaire assesses to severity of symptoms and treatment effects in athletes with patellar tendinopathy. The purpose of this study was to translated VISA-P questionnaire into Turkish language and to determine its validity and reliability. METHODS: The English version of VISA-P questionnaire was translated into Turkish according to the internationally recommended guidelines. Test-retest reliability was determined on 89 participants with time interval 24 h. To determine validity of Turkish VISA-P, 31 (17 male, 14 female) healthy students, 34 (20 male, 14 female) patients with patellar tendinopathy (diagnosed by physical examination and ultrasonography) and 24 (16 male, 8 female) volleyball players (at risk populations) were completed VISA-P-Tr. Internal consistency was determined with Cronbach's alpha. Intraclass correlation coefficients (ICCs) were calculated to analyse test-retest reliability. To assessment of discrimination, VISA-P-Tr scores compared all groups using the Mann-Whitney-U test. RESULTS: The VISA-P-Tr questionnaire showed good test-retest reliability (The Cronbach's alpha was 0.79 and 0.78 respectively and ICC was 0.96). The VISA-P-Tr score (mean ± SD) were 93.7 ± 8.9 and 94.0 ± 8.1 for healthy students, 81.1 ± 13.7 and 80.7 ± 13.4 for volleyball players, 58.8 ± 12.1 and 58.5 ± 11.0 for athletes with patellar tendinopathy. CONCLUSION: The translated Turkish version of VISA-P has good internal consistency and good reliability and validity. Therefore VISA-P-Tr is useful to evaluate symptoms and follow the treatment effect in athletes with patellar tendinopathy.

Psychiatric and functional evaluation of professional athletes following anterior cruciate ligament reconstruction.

OBJECTIVE: The aim of this study is to evaluate early phase depression and anxiety in the proffessional athletes who underwent anterior cruciate ligament (ACL) reconstruction and compare them with the functional improvement of knee. METHODS: Thirty-eight patients (35 males, 3 females; mean age±SD: 26.84±8.03) were included in this study. Measurements were obtained immediately following the operation and at Week 6 of postoperative rehabilitation. Depression and anxiety symptoms were evaluated by the Hospital Anxiety and Depression Scale (HADS), and knee function was evaluated by Lysholm Knee Scoring Scale (LKSS). RESULTS: Change in total LKSS scores from the time of admission (56.4±20.2) to the end of the sixth week (78.7±13.8) was significant (t=-8.21, p<0.001). Neither the HADS depression nor the HADS anxiety scores were above the cutoff values in the 2 assessments. Significant difference was noted in HADS anxiety scores between the time of admission (6.21±3.50) and at the sixth week (5.33±3.33) (t=2.02, p=0.05). However, HADS depression scores were not statistically different between the 2 evaluations (5.95±3.68 and 5.35±3.50 at admission and Week 6 week, respectively) (t=1.07, p=0.29). Changes between the 2 LKSS and HADS anxiety assessments were negatively correlated (r=-0.49, p=0.002), but there no correlation was detected between the total LKSS and HADS score changes. CONCLUSION: The decline of the signs of anxiety and depression at the sixth week of rehabilitation indicate that proper rehabilitation positively affects the emotional status of ACL reconstruction patients.

Acute traumatic tear of latissimus dorsi muscle in an elite track athlete.

Soft tissue injuries constitute 30-50% of all sports related injuries; however, injury to the latissimus dorsi muscle is quite rare with only a few cases reported in the literature. Herein, we describe an acute traumatic tear of the latissimus dorsi muscle in an elite track athlete, which has not been reported in the track and field sports before. The injury was caused by forceful resisted arm adduction that took place at hurdling and starting from the block. A pseudotumor appearance in the axillary region was misdiagnosed as a mass. The diagnosis was made by ultrasound alone and the patient was managed conservatively.
