Introduction: Stroke survivors can experience various consequences that affect their physical and psychological balance. Yoga seems to be relevant for this population as it allows to work on both the body and the mind. The first objective of this study was to investigate the non-inferiority of yoga compared with conventional physical activity in improving physical function in patients with chronic post-stroke sequelae. The secondary objective was to investigate the superiority of yoga in improving the mental health of these patients. Methods: A randomized controlled trial was conducted. Thirty-six patients were randomized into two groups to practice a yoga program (YOG'AVC) or the Fitness and Mobility Exercise (FAME) program. Patients were assessed in a blinding mode pre- (T0) and post-program (T1) and 3–4 months after completion (T2). The physical assessments were the Berg Balance Scale, timed up and go test, 6-minute walk test, and quadriceps strength measured by hand-held dynamometer. Questionnaire assessments were: Activities-specific Balance Confidence Scale–Simplified, State-Trait Anxiety Inventory, Beck's Depression Inventory, and the Reintegration to Normal Living Index. Results: The YOG'AVC program was not inferior to the FAME program in improving balance, functional mobility and muscle strength. Both groups showed significant improvement (p < 0.05) between T0 and T1 in their anxiety, depression, and reintegration to normal life scores, with no significant difference between groups. Discussion: Both programs seem to be valuable in improving the physical abilities and psychological well-being of chronic post-stroke patients. However, further studies are required to confirm the difference between these programs. [ABSTRACT FROM AUTHOR]

Endometriosis is a painful gynecological disorder that affects many women. Constant treatments and contraception changes affect women looking for solutions to treat and limit the problems caused by endometriosis. The current narrative review discusses the effects of physical activity on the management, pain, and quality of life in patients with endometriosis. Findings suggest that body awareness practices such as Hatha yoga, the Jacobson method, and progressive muscle relaxation reduce pain and stress and improve the quality of life associated with endometriosis. It also highlights the current knowledge gap on available evidence and future research. Moreover, care must be taken when considering patients' physical abilities and goals and avoiding intense physical activities. The forms of endometriosis and its symptoms vary from one woman to another, so it is important to perform studies with various nonmedicinal or surgical techniques. It is important to continue randomized controlled trials to obtain more data on the benefits of physical activity in women with endometriosis and also to identify what types of activities could be beneficial to combat pain symptoms and improve the daily lives of women with endometriosis. Synopsis: Body awareness practices such as Hatha yoga, the Jacobson method, and progressive muscle relaxation reduce pain and stress and improve the quality of life in women with endometriosis.

Background: In patients with obesity and metabolic syndrome (MetS), lifestyle interventions combining diet, in particular, and physical exercise are recommended as the first line treatment. Previous studies have suggested that leucine or arginine supplementation may have beneficial effects on the body composition or insulin sensitivity and endothelial function, respectively. We thus conducted a randomized controlled study to evaluate the effects of a supervised adapted physical activity program associated or not with oral supplementation with leucine and arginine in MetS-complicated patients with obesity. Methods: Seventy-nine patients with obesity and MetS were randomized in four groups: patients receiving arginine and leucine supplementation (ALs group, n = 20), patients on a supervised adapted physical activity program (APA group, n = 20), patients combining ALs and APA (ALs+APA group, n = 20), and a control group (n = 19). After the baseline evaluation (m0), patients received ALs and/or followed the APA program for 6 months (m6). Body composition, MetS parameters, lipid and glucose metabolism markers, inflammatory markers, and a cardiopulmonary exercise test (CPET) were assessed at m0, m6, and after a 3-month wash-out period (m9). Results: After 6 months of intervention, we did not observe variable changes in body weight, body composition, lipid and glucose metabolism markers, inflammatory parameters, or quality of life scores between the four groups. However, during the CPET, the maximal power (Pmax and Ppeak), power, and O2 consumption at the ventilatory threshold (P(VT) and O2(VT)) were improved in the APA and ALs+APA groups (p < 0.05), as well as the forced vital capacity (FVC). Between m6 and m9, a gain in fat mass was only observed in patients in the APA and ALs+APA groups. Conclusion: In our randomized controlled trial, arginine and leucine supplementation failed to improve MetS in patients with obesity, as did the supervised adapted physical activity program and the combination of both. Only the cardiorespiratory parameters were improved by exercise training. [ABSTRACT FROM AUTHOR]

The objective of present study is to investigate the effects of walk training with and without blood flow restriction (BFR and no-BFR) on lipid profiles, inflammatory and haematological factors in over-weighed men. Participants were divided into BFR (n = 9) or no-BFR (n = 9) groups. Both groups were exposed to 8-week walk training on a treadmill: 3 sessions/week at a speed of 50 m/min, 5 sets × 2 min/session. There were differences in pre- to post-levels of (TG) and fibrinogen in the BFR group (p ≤ 0.05) that were accompanied by changes in red blood cells (RBC), haemoglobin (HGB) and haematocrit (HCT) levels (p ≤ 0.05). RBC levels were increased in the BFR group (p ≤ 0.05). The groups differed in their mean corpuscular volume (MCV) and mean corpuscular haemoglobin concentration (MCHC). These findings suggest the efficiency of BFR walk training in individuals exposed to chronic diseases associated with overweight, such as metabolic syndrome. [ABSTRACT FROM AUTHOR]

PURPOSE: This study determined the validity and reliability of a new specific field test that was based on the scientific data from the latest research. METHODS: Seventeen international-level karatekas participated in the study: 14 men (age 24.1 ± 4.6 y, body mass 65.7 ± 10.8 kg) and 3 women (age 19 ± 3.6 y, body mass 54.1 ± 0.9 kg). All performed the new karate-specific test (KST) 2 times (test and retest sessions were carried out on separated occasions 1 wk apart). Thirteen men also performed a laboratory test to assess maximal oxygen uptake (VO2max). RESULTS: Test-retest results showed the KST to be reliable. Peak oxygen uptake (VO2peak), peak heart rate (HRpeak), blood lactate concentration, rating of perceived exertion, and time to exhaustion (TE) did not display a difference between the test and the retest. The SEM and ICC for relative and absolute VO2peak and TE were <5% and >.90, respectively. Significant correlations were found between VO2peak (mL • kg-1 • min-1) and TE measured from the KST (r = .71, 95%CI 0.35-0.88, P < .0001). There was also no significant difference between VO2peak measured from the KST and VO2max recorded from the cycle-ergometer laboratory test (55.1 ± 4.8 vs 53.2 ± 6.6 mL • kg-1 • min-1, respectively; t = -1.85, df = 12, P = .08, dz = 0.51 [small]). The Bland and Altman analyses reported a mean difference (bias) ± the 95% limits of agreement of 1.9 ± 7.35 mL • kg-1 • min-1. CONCLUSIONS: This study showed that the new KST test, with effort patterns replicating real karate combat sessions, can be considered a valid and reliable karate-specific field test for assessing karatekas' endurance fitness.

The relationship between foot kinematics and the development of lower extremity musculoskeletal disorders (MSD) has been the focus of recent attention. However, most studies evaluated static foot type and not dynamic foot function. The purpose was to compare lower limb and foot kinematics, and plantar pressures during gait in physically active individuals with pronated and non‐pronated foot function. Foot function in 154 adult participants was documented as pronated (n = 63) or neutral (n = 91) using 2 established methods: The Foot Posture Index and the Center of Pressure Excursion Index. Difference between the groups in triplanar motion of the lower limb during barefoot gait was evaluated using a 3D motion capture system incorporating the Oxford Foot Model. Dynamic parameters of plantar pressure were recorded using a pressure platform. Anterior‐posterior pelvic tilt range of motion (ROM), peak knee internal rotation, forefoot dorsiflexion ROM, peak forefoot abduction, and rearfoot eversion were all increased in those with pronated foot function. Hallux contact time and time to peak force under the medial forefoot were increased with pronated foot function, and maximal force under the lateral forefoot was reduced. Pronated foot function affected the whole lower limb kinematic chain during gait. These kinematic alterations could increase the risk of developing MSD. Further studies should elucidate the relationship between pronated foot function and MSD, and, if confirmed, foot function should be evaluated in clinical practice for patients with lower limb and low back pain.

The purpose of this study was to determine the relationships between velocity, stroke length, and stroke rate in freestyle competitive events in order to compare male and female swimmers' results and assess their relationships with anthropometric characteristics. Three hundred three male and 325 female swimmers of national and international levels were tested during competition. Solutions adopted in each freestyle event had specific characteristics affecting the stroke rate/stroke length ratio according to distance of the race. Differences in velocity between men and women primarily resulted from differences in stroke length. If the velocity and stroke rate/stroke length ratio depend on the distance swum and the sex of the swimmer, this survey shows the nondiscriminating aspect of anthropometric characteristics. Although swimmers achieved very similar velocity values with different combinations of stroke length and stroke rate, one must appreciate the average time and space characteristics currently used by the best male and female swimmers to optimize their performances.

To identify the anterior cruciate ligament (ACL) laxity thresholds and to evaluate the utility of this measure in case of onset of knee injury for elite women handball players. Anterior laxity was measured by an arthrometer. Data on 29 elite women handball players and 20 sedentary women were collected. Among the handball group, 9 participants suffered from full-thickness ACL tears. The recorded variables were the anterior knee laxities at pressure load (PL) of 134 N (PL134N) and 250 N (PL250N) on the upper calf, which allowed assessment of the inter-leg comparison by calculating the differential laxity thresholds and the differential slope coefficients. Considering the healthy knee as a reference within the injured players, the laxity thresholds were identified, and the diagnostic value of the tests was assessed. The handball players without a full-thickness tear presented lower knee laxity than the sedentary women, and 75% were diagnosed with pathologic laxity in at least one of the knee joints, compared to 10% of sedentary women. The differential laxity threshold was identified between the handball players without a full-thickness tear and those with a full-thickness tear at 1.5 mm with PL134N and 2.2 mm with PL250N. The best diagnostic result was obtained using PL250N (area under the curve = 0.95). Handball practice is associated with specific laxities that are rarely seen in the general population. The ACL laxity thresholds may be useful measures to check the state of the ACL and to suggest full-thickness tears, as joint laxity appears to be a factor contributing to ACL tears in female handball players.

The authors investigated and compared the energy expenditure and postural coordination of two groups of healthy subjects on a mechanical horse at 4 increasing oscillation frequencies. Energy expenditure was assessed from the oxygen consumption, respiratory quotient, and heart rate values, and postural coordination was characterized by relative phase computations between subjects (elbow, head, trunk) and horse. The results showed that the postural coordination of the riders was better adapted (i.e., maintenance of in-phase and antiphase) than that of the nonriders, but the energy expenditure remains the same. Likewise, we observed an energy system shifting only for nonriders (from aerobic to lactic anaerobic mode). Finally, cross-correlations showed a link between energy expenditure and postural coordination in the riders (i.e., effectiveness). [ABSTRACT FROM AUTHOR]

The aim of this study was to define the time-motion (i.e., fighting, preparatory and breaking activity), technical (i.e., attack, timed-attack, counterattack, blocking and grasps) and tactical (i.e., upper limb, lower-limb, combination and throwing) profiles of the senior top-level karate competition played under the most recent rules of the International Karate Federation in relation to gender, match outcome and weight categories. Time-motion, tactical actions and technical executions were investigated of senior karatekas (n = 60) during the Karate World Championship. The referee’s decisions caused an overall activity-to-break ratio of ~1:1.5 with a significant difference (P = 0.025) between karateka’s weight categories (light = 1:1.5; middle = 1:2 and heavy = 1:1). High-intensity actions (i.e., attack and defensive actions performed quickly and powerfully) were higher in male compared to female athletes. Top-level karatekas used upper limb techniques more than lower limb ones, with both applied in the head more than in the body. For the high-intensity-actions to pause ratio and the percentage of combined techniques, light weight category was significantly higher than middle weight category. These findings suggest that training programs may need to be specific to the requirements of the gender and weight categories. [ABSTRACT FROM PUBLISHER]

Background. This study attempted to establish physical and physiological characteristics of different high-level combat sport athletes (judo, karate, and taekwondo) and to determine possible differences between these athletes. Material and methods. Fifty-four elite judo (n = 19), karate (n = 19) and taekwondo (n = 16) athletes took part in the present study. The experimental design consisted of two test sessions. On the first one, athletes performed the squat jump (SJ), countermovement jump (CMJ), and a maximal treadmill test to determine O2max. The second session included the five jump test (5JT), 30m sprint, and one repetition-maximum (1RM) during three exercises: bench-press, half-squat and lying row. Results. The results showed that SJ and CMJ heights and 5JT performances were higher in karate athletes than in judo and taekwondo athletes. Conversely, bench-press, half-squat and lying row 1RM were higher in judo athletes compared to karate and taekwondo athletes. However, no significant difference was found in O2max and 30-m sprint between groups. Conclusion. These results can be used for athlete selection in the different combat sports.

La fatigue est considérée comme chronique lorsqu'elle dure plus de 6 mois et qu'elle n'est pas améliorée par le repos. L'évaluation de la fatigue chronique (FC) reste difficile, les outils existants sont soit trop généraux, soit élaborés pour une pathologie spécifique. Associée ou non à une autre maladie chronique, elle constitue un phénomène complexe, multidimensionnel et subjectif expliquant le manque de consensus sur sa définition. L'objectif est d'explorer l'expérience des patients afin de construire une échelle d'autoévaluation de la FC. Trente et une personnes (neuf patients souffrant d'encéphalomyélite myalgique, douze patients ayant une maladie inflammatoire chronique de l'intestin et dix participants tout-venant) ont été interrogées sur la reconnaissance, la description et le vécu de leur fatigue. Leurs discours ont été étudiés par une analyse lexicométrique et une analyse phénoménologique interprétative. Les résultats ont montré des discours significativement différents entre les groupes cliniques et les participants tout-venant. En revanche, les deux groupes de patients présentent quatre dimensions communes : contraintes générées par la FC, conséquences physiques, conséquences sur la vie personnelle et conséquences sur les relations interpersonnelles. Ces dimensions suggèrent que le vécu des patients est plus complexe que ce qu'évaluent les outils existants. Ainsi, ces résultats plaident en faveur de l'élaboration d'une échelle d'évaluation de l'asthénie chronique construite à partir de l'expérience des participants. Asthenia is considered chronic when it extends over time for more than six months and remains unresolved by rest. Currently, chronic asthenia is difficult to assess as the existing scales are either too generic or, conversely, designed for asthenia associated with a specific pathology that hinders the correct evaluation of the associated fatigue. This is, however, problematic when it comes to chronic asthenia – whether or not it is associated with other chronic diseases – because it constitutes complex, multidimensional and largely subjective phenomena, all of which account for the lack of consensus in the literature about this condition. Therefore, any elaboration of a tool designed to evaluate fatigue in myalgic encephalomyelitis (ME) requires a thorough exploration of the patients' experience of this condition. This was precisely the main goal of the present study. Semi-structured interviews were collected from 31 individuals: a group of patients with ME (n = 9), a group of patients with inflammatory bowel disease (IBD, n = 12), and a group of control participants (n = 10), in which fourteen men with a mean age of 39.33 (±11.30) and seventeen women with a mean age of 43.5 (±12.8). The interviews focused on their perception of their relatives' fatigue and the description of their own fatigue. For the two groups of patients (ME, IBD), two additional themes were discussed: the evolution of their fatigue and their relationships with healthcare professionals. Two methods were used to analyze these interviews: lexicometric analysis (using IRaMuTeQ software) and an interpretative phenomenological analysis (IPA). This choice of combining quantitative and qualitative methods limits the subjectivity in discourse analysis. The lexicometric analysis revealed a significantly different content of discourse depending on the group of participants. The discourse of control participants focused on "normal" fatigue, which results from daily activities and can be resolved with rest. The IBD group emphasized the importance of the quality of sleep, the necessity of more frequent rest and fatigue-related pain. Finally, the discourse of participants in the ME group focused on the intensity of the manifestations of fatigue and the unpredictability of the need for rest which affects their everyday life. The interpretative phenomenological analysis revealed six major themes: origins of fatigue, different types of asthenias, its manifestations, its consequences, recovery time, and relationships with healthcare professionals. For all these themes, the discourses of ME group suggested a more intense and unpredictable fatigue than was the case for the two other groups. Taken together, the two types of analyses converged toward four common dimensions of fatigue that are experienced by the two groups of patients (as compared to the control group): constraints generated by chronic fatigue, consequences for their physical condition, their personal life, and their interpersonal relationships. These four dimensions appeared in the discourses of both patient groups, but the expressions about their fatigue and the relative impact were different. This study demonstrated that the experience of chronic asthenia is more complex than what can be assessed using existing specific tools, but also more specific than the dimensions of fatigue comprised in generic tools. These findings, therefore, confirmed the necessity for the developments of prospective assessment scales of chronic asthenia that take into account the patients' subjective experience of fatigue.

The article proposes solutions to the physical fitness challenge associated with preparation for the FIFA World Cup Qatar 2022. It discusses the correlation of sleep quality, stress and levels of exposure to training loads with a player's physical fitness status. Recommendations for players' preparation include increase in training load during the national training camp, communication between club medical and technical staff to reduce injury incidence and external workload management.

The aim of this study was to examine the relationship between the physiological data from subjects and their reported sensory experiences during two types of recovery methods following a handball training session. Female handball players (average age: 21.4 ± 1.3 years; weight: 59.2 ± 3.3 kg; height: 158 ± 3 cm; body mass index, 23.4 ± 2.0 kg.m -2 ) carried out an athletic training session (rating of perceived exertion RPE: 14.70 ± 0.89) with either a passive recovery (PR) period or cold water immersion (CWI) for 14 min) (cross-over design). Physiological data were collected during the recovery period: CWI had a greater effect than PR on heart rate (HR; bpm), the higher frequencies (HF) of heart rate variability (HRV: 46.44 ± 21.50 vs. 24.12 ± 17.62), delayed onset muscle soreness (DOMS: 1.37 ± 0.51 vs. 2.12 ± 1.25), and various reported emotional sensations. Spectrum HRV analysis showed a significant increase in HF during CWI. Sensorial experiences during the recovery periods were gathered from verbatim reports 24 h later. Players' comments about CWI revealed a congruence between the physiological data and sensorial reports. They used words such as: " thermal shock ," " regeneration ," " resourcefulness ," " dynamism ," and " disappearance of pain " to describe their sensations. In conclusion, this study demonstrated the link between physiological and experiential data during CWI and we propose that action of the parasympathetic system on the autonomic nervous system can, at least in part, explain the observed correlations between the corporeal data measured and the sensorial experiences reported., (Copyright © 2020 L'Hermette, Castres, Coquart, Tabben, Ghoul, Andrieu and Tourny.)

Background: The twofold aim of the study was to: 1) compare the gas exchange threshold (GET), the first oxyhemoglobin inflection point ([O2Hb]-T), and perceptual threshold as determined during an incremental exercise test, and 2) investigate the link between each threshold and time-to-exhaustion during heavy intensity exercise., Methods: Fourteen competitive cyclists performed an incremental exercise test to exhaustion on a cycloergometer to determine the different thresholds and peak workload (Wpeak). The participants then performed a sub-maximal constant workload test (90% Wpeak) to exhaustion to determine time-to-exhaustion. The thresholds were identified from: 1) the first breakpoint in the oxygen uptake vs. carbon dioxide output curve (GET), 2) the [O2Hb]-T, and 3) a rating of 13 in perceived exertion (perceptual threshold: RPE13-T)., Results: Oxygen uptake at the different thresholds was not significantly different (P>0.05). Moreover, GET and [O2Hb]-T were significantly correlated: 1) to each other (r≥0.79; P≤0.001), and 2) to time-to-exhaustion (r=0.81 and r=0.72, respectively; P<0.01). RPE13-T, however, was not significantly correlated with the time-to-exhaustion (P=0.148)., Conclusions: The anaerobic threshold as identified from GET was concomitant to [O2Hb]-T. Both thresholds were correlated to time-to-exhaustion, and could therefore be used as a performance index in middle-duration events.
