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.

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.

Doppler ultrasound evaluation of the structural and hemodynamic changes in the brachial artery following two different exercise protocols.

PURPOSE: Examine the effects of incremental and submaximal exercise on structural and hemodynamic changes in the brachial artery flow parameters using Doppler ultrasonography. MATERIALS AND METHODS: Twenty four healthy sedentary males (aged 19.54+/-0.59) performed submaximal (15 minutes heart rate to 75% maximal) and incremental (workload was increased 20W every 3 minutes until exhaustion) exercises by upper extremity ergometer. Before and after exercises the brachial artery diameter, peak systolic maximum velocity (Vmax), end-diastolic minimum velocity (Vmin) and time-averaged mean flow velocity (Vmean), volume blood flow and flow waveform patterns were recorded in a controlled environment. RESULTS: The diameter of the brachial artery, flow velocities, and blood flow increased significantly after each exercise protocol (p < 0.001). The Vmax (p < 0.05), Vmean (p < 0.01), and volume blood flow (p < 0.01) after the incremental exercise were significantly higher than those measured after the submaximal exercise. However, no significant differences were noted between the two exercise protocols when arterial diameters and Vmin were concerned. The flow pattern was monophasic in all subjects after incremental exercise. Nevertheless, the flow pattern remained triphasic in two of the subjects after submaximal exercise. CONCLUSION: Blood flow velocities played important role in hemodynamic mechanism than conduit arterial diameter during arm exercises. Changes in conduit artery diameter did not significantly contribute to blood flow increase during high and moderate intensity exercises. There is minimal variation in waveform shapes of normal individuals after exercise. Doppler ultrasonography proved a practical tool in the studies of the dynamic responses of blood flow and vascular resistance during rest and exercises.

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.
