High Physical Activity Volume Is Associated With an Increase in the Calibre of the Lower Limb Veins Without Impact on Functional Discomfort: the VARISPORT Study.

OBJECTIVE: The relationship between physical activity and lower limb veins is complex. If a sedentary lifestyle is considered to be negative on lower limb veins, specific information on physical activity varicose vein volume is sparse, especially the effect of high physical activity volume. The main objective of the VARISPORT study was to evaluate lower limb veins (clinically, morphologically, and haemodynamically) and chronic venous disease symptoms in subjects exposed to high physical activity volume compared with a group of non-exposed subjects. METHODS: A cross sectional study compared a group of high exercise training volume volunteers (more than eight hours of uninterrupted vigorous intensity physical activity per week for more than six months: high physical activity volume group, HPAV group) with a volunteer control group matched for age, sex, and body mass index. Clinical examination was performed to determine the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) classification of each subject and the Carpentier score was used to assess symptoms related to possible chronic venous disease. Duplex ultrasonography was used to assess vein diameters and reflux in the deep and superficial veins. RESULTS: One hundred and nineteen subjects were included in each group. The lower limb veins (deep and superficial) were significantly more dilated in the HPAV group. More reflux was found in the great saphenous veins and non-saphenous veins in the HPAV group. High physical activity volume was associated with a higher frequency of visible varicose veins (stage C2 of the CEAP classification), odds ratio 3.37 (95% confidence interval 1.66 - 7.25) without impact on functional discomfort (44 subjects with a Carpentier score ≥ 1 in each group). CONCLUSION: The VARISPORT study reported an increase in the calibre of the lower limb veins without impact on functional discomfort. Further studies are needed to determine whether these athletic veins are truly pathological varicose veins or simply an adaptation to high physical activity volumes.

Systematic review of adapted physical activity and therapeutic education of patients with chronic venous disease.

BACKGROUND: Chronic venous disease (CVD), comprising impaired lower limb venous return, will lead to chronic distal venous pressure overload manifested by various clinical signs and symptoms and resulting in diminished quality of life. The CEAP (Clinical, Etiology, Anatomy, and Pathophysiology) classification of CVD distinguishes six stages (C0-C6) using clinical, etiologic, anatomic, and pathophysiologic parameters. In the present study, we analyzed the effects of adapted physical activity (APA) and patient-oriented therapeutic education (PTE) programs on the clinical signs, symptoms, and quality of life of patients with CVD. METHODS: Our analysis, in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) recommendations, included a search of PubMed, CINAHL and LiSSa databases, using a single search equation. RESULTS: A total of 21 studies were selected for analysis. The analysis revealed first, that patients at stage C0 to C5 had had access to an APA program. This therapy alleviated the clinical signs and symptoms and improved the patients' quality of life. The beneficial effects of APA were greater in the programs that had included aquatic activities than in the program that were exclusively dry-land programs. Second, patients at stage C6 had predominantly followed a PTE program. This therapy showed beneficial effects on the clinical signs and symptoms. However, the quality of life had rarely been assessed. CONCLUSIONS: At present, APA and PTE programs comprise useful and complementary therapeutic options for the care of patients with CVD. Two of the studies included in our review had evaluated the effects of combining these two approaches, notably in the context of balneotherapy, and reported promising results.

May Thurner syndrome revealed by left calf venous claudication during running, a case report.

BACKGROUND: May Thurner syndrome is relatively unknown to physicians, its management is well standardized and the outcomes of treatment are satisfactory in the short to medium term. CASE PRESENTATION: We report the case of a patient who suffered from venous claudication during running which impaired their quality of life, decreased their athletic performance and resulted in a career change. May Thurner syndrome diagnosis was made after extensive hemodynamic analysis of a lower limb venous duplex ultrasound scan. This diagnosis was later confirmed by imaging. Subsequent endovascular care provided rapid and sustained clinical improvement. CONCLUSION: The main difficulties with the May Thurner syndrome are to think about it and know how to look for it; indeed the misdiagnosis time can be long. When diagnosis is made, treatment could be easy and effective.

Benefits of Compression Garments Worn During Handball-Specific Circuit on Short-Term Fatigue in Professional Players.

Ravier, G, Bouzigon, R, Beliard, S, Tordi, N, and Grappe, F. Benefits of compression garments worn during handball-specific circuit on short-term fatigue in professional players. J Strength Cond Res 32(12): 3528-3536, 2018-The purpose of this study was to investigate the benefits of full-leg length compression garments (CGs) worn during a handball-specific circuit exercises on athletic performance and acute fatigue-induced changes in strength and muscle soreness in professional handball players. Eighteen men (mean ± SD: age 23.22 ± 4.97 years; body mass: 82.06 ± 9.69 kg; height: 184.61 ± 4.78 cm) completed 2 identical sessions either wearing regular gym short or CGs in a randomized crossover design. Exercise circuits of explosive activities included 3 periods of 12 minutes of sprints, jumps, and agility drills every 25 seconds. Before, immediately after and 24 hours postexercise, maximal voluntary knee extension (maximal voluntary contraction, MVC), rate of force development (RFD), and muscle soreness were assessed. During the handball-specific circuit sprint and jump performances were unchanged in both conditions. Immediately after performing the circuit exercises MVC, RFD, and PPT decreased significantly compared with preexercise with CGs and noncompression clothes. Decrement was similar in both conditions for RFD (effect size, ES = 0.40) and PPT for the soleus (ES = 0.86). However, wearing CGs attenuated decrement in MVC (p < 0.001) with a smaller decrease (ES = 1.53) in CGs compared with regular gym shorts condition (-5.4 vs. -18.7%, respectively). Full recovery was observed 24 hours postexercise in both conditions for muscle soreness, MVC, and RFD. These findings suggest that wearing CGs during a handball-specific circuit provides benefits on the impairment of the maximal muscle force characteristics and is likely to be worthwhile for handball players involved in activities such as tackles.

Long-term donor-site morbidity after vascularized free fibula flap harvesting: Clinical and gait analysis.

The aim of this study was to determine the clinical morbidity and changes in gait temporal spatial parameters after harvesting of a vascularized free fibula flap. This study included 11 patients (mean age: 52 ± 17 years) and 11 healthy controls (mean age: 50 ± 14 years). The patients were assessed between 5 and 104 months post surgery. The study consisted of a subjective functional evaluation with two validated clinical scores (Kitaoka Score and Point Evaluation System (PES) score), clinical and neurological examination of the legs, and evaluation of gait temporal spatial parameters while walking at a comfortable speed. The mean functional Kitaoka score was 78/100, and the mean PES score of 12.18 was considered average. At the time of the review, five patients had sensory disorders, two had toe deformities, and eight had pain at the donor site. The gait analysis showed that the patient's comfortable walking speed was significantly lower in comparison to that of the controls, and that stride length and cadence were reduced. In addition, most of the gait-specific parameters were significantly different. The donor leg displayed greater variability during walking. To reduce the risk of falling, this study revealed that the patients' gait pattern had changed as they took a more cautious approach during walking. Early rehabilitation is expected to help improve and/or restore the physical abilities of patients after harvesting of the vascularized free fibula flap.

Compression garments and exercise: no influence of pressure applied.

Compression garments on the lower limbs are increasingly popular among athletes who wish to improve performance, reduce exercise-induced discomfort, and reduce the risk of injury. However, the beneficial effects of compression garments have not been clearly established. We performed a review of the literature for prospective, randomized, controlled studies, using quantified lower limb compression in order to (1) describe the beneficial effects that have been identified with compression garments, and in which conditions; and (2) investigate whether there is a relation between the pressure applied and the reported effects. The pressure delivered were measured either in laboratory conditions on garments identical to those used in the studies, or derived from publication data. Twenty three original articles were selected for inclusion in this review. The effects of wearing compression garments during exercise are controversial, as most studies failed to demonstrate a beneficial effect on immediate or performance recovery, or on delayed onset of muscle soreness. There was a trend towards a beneficial effect of compression garments worn during recovery, with performance recovery found to be improved in the five studies in which this was investigated, and delayed-onset muscle soreness was reportedly reduced in three of these five studies. There is no apparent relation between the effects of compression garments worn during or after exercise and the pressures applied, since beneficial effects were obtained with both low and high pressures. Wearing compression garments during recovery from exercise seems to be beneficial for performance recovery and delayed-onset muscle soreness, but the factors explaining this efficacy remain to be elucidated. Key pointsWe observed no relationship between the effects of compression and the pressures applied.The pressure applied at the level of the lower limb by compression garments destined for use by athletes varies widely between products.There are conflict results regarding the effects of wearing compression garments during exercise.There is a trend towards a beneficial effect of compression garments worn during recovery.
