Musculoskeletal Pain, Mood, and Sports Injury in Wheelchair Power Soccer Players.

CONTEXT: Wheelchair Power Soccer (WPS) is the only team sport that allows the participation of people with severe physical disabilities who require the daily use of motorized wheelchairs. These individuals may live with chronic pain due to the characteristics of the disabilities and treatments, interfering with their health and limiting their participation in sports. OBJECTIVES: To investigate the prevalence of musculoskeletal pain and its relationship with mood in WPS players and to analyze the incidence of traumatic injuries during a championship. METHODS: A prospective, longitudinal study was carried out on 30 WPS athletes (93.33% male) with a mean (SD) (range) age of 22.37 (9.79) (47) years. Data collection was performed during a South American WPS Championship lasting 3 days, with: investigation of the presence of musculoskeletal pain and mood through a questionnaire; investigation of the occurrence of traumatic injuries through match observation; and confirmation of the occurrence of traumatic injuries through access to medical department records. RESULTS: About 30% (n = 9/30) of the sample presented some pain on the day of evaluation, with an intensity of 5.67 (3.35) (10) points on the visual analog scale. The most common regions of pain were the lower back (13.3%, n = 4/30), thoracic (10%; n = 3/30), and cervical (10%; n = 3/30) areas of the spine. A total of 46.7% (n = 14/30) reported pain in the month before data collection but of less intensity (2.56 [4] [10] points), the most common regions being the lower limbs (20%; n = 6/30) and cervical spine (20%; n = 6/30). Among the between-group comparisons (ie, participants with pain vs without pain), no relationship was observed between mood state and pain. No traumatic injuries were identified during the competition. CONCLUSION: The presence of musculoskeletal pain was common in WPS players, but it was not related to mood. As no traumatic injuries were observed during the championship, this modality seems to be safe for people with physical disabilities in general.

The Perception of Nursing Professionals Working in a Central Sterile Supplies Department regarding Health Conditions, Workload, Ergonomic Risks, and Functional Readaptation.

Background: The central sterile supply department (CSSD) is wrongly seen as a place in the hospital environment that does not require skills and physical effort, being commonly a hospital sector for the relocation of functionally-readapted professionals. However, CSSD is a work environment that demands professional experience and presents itself as a sector that does not have a healthy work environment. This study aims to evaluate the frequency of comorbidities and functionally-readapted people among nursing professionals allocated to a CSSD and, also, to seek the perception of these professionals about the ergonomic risks and the degree of difficulty to perform activities within a CSSD. Methods: This is a cross-sectional study that analyzed the opinions of nursing professionals who work in the CSSD of public hospitals in Rio de Janeiro, Brazil. Nurses, nursing technicians and nursing assistants aged ≥18 years were included. Results: Seventy-two nursing professionals were consecutively evaluated. It was observed that 43 of them (59.7%) had never worked in a CSSD. The most prevalent comorbidity in the present study was chronic rhinosinusitis, observed in more than half of the sample, although it is interesting to note the high frequency of participants with work-related musculoskeletal disorders (WMSD) and repetitive strain injuries (RSI). There is a relationship between previous work in a CSSD and the ability to identify surgical tweezers by visual recognition (p=0.031). There is a relationship between the time the participant had previously worked in the hospital and the skill regarding the information contained in the conference folders for preparing the tray surgical procedures (τb = -0.34, p=0.001). Conclusion: Almost a third of nursing professionals working in a CSSD are rehabilitated, with a high prevalence of WMSD and RSI. The commitment of managers to an internal health policy aimed at workers is necessary for health promotion.

Validity of the Polar V800 heart rate monitor for assessing cardiac autonomic control in individuals with spinal cord injury

Abstract Aim: Spinal cord injury (SCI) is associated with changes in cardiac autonomic control, that can be evaluated by heart rate variability (HRV), for which the electrocardiogram (ECG) is the gold standard. However, the use of ECG is limited to laboratory environments, and new tools are needed for this purpose and that can be applied in the routine monitoring of individuals with SCI. The present study aimed to investigate the validity of the Polar V800 heart rate monitor in assessing the cardiac autonomic control of individuals with SCI. Methods: Nineteen adult men with SCI (paraplegia n = 10; 44.5 ± 8.5 years and tetraplegia n = 9; 34.4 ± 7.5 years) participated in this cross-sectional study. The participants remained in the sitting position at rest for 10 min for the acquisition of the ECG and Polar V800 signals. The last 5-min window was used to count the beat-by-beat R-R interval series and then calculate the HRV indices (linear methods in the time and frequency domains). The study subgroups were compared, and the validity of the measurements generated with a heart rate monitor was determined using the intraclass correlation coefficient (ICC2,1) and Bland-Altman graphs. Results: Agreement analyses for the R-R intervals, SDNN, rMSSD, PNN50, SD1, LF, HF, and LF: HF ratio tended to show reliability ranging from acceptable to excellent (ICC = 0.579-0.990; P = 0.043-0.001) and acceptably narrow limits of agreement within both the group with tetraplegia and the group with paraplegia. Conclusion: The Polar V800 heart rate monitor is a valid instrument for assessing HRV in individuals with paraplegia and tetraplegia.

Effect of pre-fatiguing the triceps brachii on subsequent strength performance and myoelectric activity in the barbell, dumbbell and Smith machine bench press / Efecto de la prefatiga del tríceps braquial en el desempeño subsiguiente de la fuerza y actividad mioeléctrica en el supino recto en la barra, mancuernas y Smith Machine / Efeito da pré-fadiga do tríceps braquial no desempenho subsequente da força e atividade mioelétrica no supino reto na barra, halteres e Smith Machine

OBJECTIVE: The purpose of this study was to examine the effect of pre-fatiguing the triceps brachii on subsequent strength performance and myoelectric activity in the barbell, dumbbell, and Smith machine bench press. METHOD: Nineteen trained men participated of this study (27.9 ± 4.5 years; 1.72 ± 0.1 m; 80.3 ± 9.2 kg). Ten-repetition maximum loads were determined for the triceps extension as well as the barbell barbell, dumbbell and Smith machine bench press. Three experimental protocols were performed in a randomized design. All experimental protocols began with four sets of the triceps extension (performed with a high pulley) to repetition failure followed by four sets to repetition failure for one of three bench press modalities. Two minute-rest intervals were adopted between sets and exercises. Total repetitions (work), training volume and myoelectric activity of pectoralis major, anterior deltoid, biceps brachii, and triceps brachii were recorded during each bench press modality. RESULTS: Significantly greater activity of the biceps brachii was observed during performance of the dumbbell bench press versus barbell and Smith machine bench press. No other significant differences were observed between protocols. CONCLUSION: Therefore, considering the training volume and myoelectric activity of the synergistic muscles, similar performance across bench press modalities can be expected when preceded by performance of a triceps extension

OBJETIVO: Examinar el efecto de la prefatiga del tríceps braquial en el desempeño subsiguiente de la fuerza y actividad mioeléctrica en el supino recto utilizando barra (SRB), mancuernas (SRM) y Smith machine (SMSR). MÉTODO: En el estudio participaron 19 hombres entrenados (27.9 ± 4.5 años, 1.72 ± 0.1 m, 80.3 ± 9.2 kg). Se realizó una prueba de diez repeticiones máximas para la extensión del tríceps, así como para el supino resto utilizando barra, mancuernas y Smith Machine. Se realizaron tres protocolos experimentales en orden aleatorizado. Los protocolos consistieron de cuatro series de repeticiones de extensión del tríceps (realizado con polea alta) hasta la fatiga, seguida de cuatro series de repeticiones hasta la fatiga de una de las tres modalidades de supino. Dos intervalos de descanso de un minuto se realizaron entre series y ejercicios. Las repeticiones totales (trabajo), volumen de entrenamiento y actividad mioeléctrica de pectoral mayor, deltoides anteriores, bíceps braquial y tríceps braquial fueron registradas durante cada modalidad de supino. RESULTADOS: Se observó una actividad significativamente mayor del bíceps braquial durante la realización del supino recto con mancuerna versus barra y Smith Machine. No se observó ninguna diferencia significativa entre los protocolos. CONCLUSIONES: Por lo tanto, considerando el volumen de entrenamiento y la actividad mioeléctrica de los músculos sinérgicos, se puede esperar un rendimiento similar en las diversas modalidades de supino, cuando es precedido por la realización de una extensión de tríceps

RESULTADOS: Observou-se uma atividade significativamente maior do bíceps braquial durante a realização do supino reto halter versus barra e Smith Machine. Nenhuma outra diferença significativa foi observada entre os protocolos. CONCLUSÕES: Portanto, considerando o volume de treinamento e a atividade mioelétrica dos músculos sinérgicos, pode-se esperar um desempenho semelhante em modalidades de supino quando precedido pela realização de uma extensão de tríceps

Acute Hormone Responses Subsequent to Agonist-Antagonist Paired Set vs. Traditional Straight Set Resistance Training.

Miranda, H, de Souza, JAAA, Scudese, E, Paz, GA, Salerno, VP, Vigário, PdS, and Willardson, JM. Acute hormone responses subsequent to agonist-antagonist paired set vs. traditional straight set resistance training. J Strength Cond Res 34(6): 1591-1599, 2020-The purpose of this study was to compare acute hormone responses and rating of perceived exertion (OMNI-Res) subsequent to the agonist-antagonist paired set (PS) vs. the traditional straight set (TS) resistance training method. Twelve recreationally trained men (25.7 ± 4.7 years, 173 ± 6.3 cm and 71.5 ± 6.6 kg) participated in the current study. After 10 repetition maximum (RM) load determination, each subject performed the following 2 experimental sessions in random order: TS session-3 sets of 10 repetitions at 85% of 10RM for the machine seated row and barbell bench press with 2-minute rest intervals between sets; and PS-3 sets of 10 repetitions with 85% of 10RM alternating machine seated row and barbell bench press for the total of 6 PSs with 2-minute rest intervals between sets. Total testosterone (TT), free testosterone (FT), cortisol, TT/cortisol ratio, growth hormone (GH), and blood lactate concentrations were measured before workout and immediately after workout and 15 and 30 minutes after workout. The OMNI-RES was recorded at the end of each set for both exercises within each session. Under the TS session, TT significantly increased immediately post-workout vs. the pre-workout time point. For the PS session, TT significantly decreased at 30-minute post-workout vs. the immediate post-workout time point, whereas, FT significantly increased immediately post-workout and 15-minute post-workout vs. the pre-workout time point. For the TS session, GH significantly increased immediately post-workout, and at the 15- and 30-minute post-workout time points vs. the pre-workout time point, respectively. For the PS session, GH was significantly increased immediately post-workout vs. the pre-workout time point. Blood lactate significantly increased at all post-workout time points vs. the pre-workout time point under both sessions. The cortisol and TT/cortisol ratio showed no differences between sessions. In conclusion, from an acute standpoint, the TS approach showed a tendency to cause greater disruption in hormone levels, despite the lack of significant differences vs. the PS approach at all time points. However, both strategies may promote similar acute hormone responses.

Effects of A Short-term Cardio Tai Chi Program on Cardiorespiratory Fitness and Hemodynamic Parameters in Sedentary Adults: A Pilot Study.

This study evaluates the effects of a short-term Cardio Tai Chi program on the cardiorespiratory fitness and hemodynamic parameters in sedentary adults. Thirty-one sedentary participants (age: 58 ± 9 years, body mass: 63 ± 12 kg) were subjected to an exercise program during 10 sessions over a 10-day period within 2 weeks. The Cardio Tai Chi program consisted in a series of three to five intervals lasting 90 s each at ∼70% maximal heart rate separated by 2-min of low-intensity recovery. Primary outcome measures were cardiorespiratory fitness (peak oxygen uptake, V˙O2peak) assessed by the Rockport walking test and resting hemodynamic parameters (systolic, diastolic, mean, and pulse pressures). We observed a significant difference of means on post-pre V˙O2peak [4.5 ml/kg/min, 95% confidence interval (CI): 3.1 to 5.8, p = 0.004], systolic blood pressure (-5.5 mmHg, 95% CI:-7.3 to -3.8, p = 0.010) and pulse pressure (-3.7 mmHg, 95% CI: -5.2 to -2.3, p = 0.028). No significant differences were observed for diastolic pressure (-1.8 mmHg, 95% CI: -2.6 to -1.0, p = 0.226), mean blood pressure (2.5 mmHg, 95% CI: 1.4 to 3.6, p = 0.302), or resting heart rate (-0.9 beat/min, 95% CI: -2.0 to 0.1, p = 0.631). Our findings suggest that engaging in a short-term Cardio Tai Chi program can improve cardiorespiratory fitness and hemodynamic parameters in sedentary adults.

Electromyographic activity of the quadriceps and gluteus medius muscles during/different straight leg raise and squat exercises in women with patellofemoral pain syndrome.

Patellofemoral pain syndrome (PPS) is characterized by anterior knee pain and affects young female adults. Physiotherapy is the most indicated treatment. The objective of the study was to analyze electromyographic activity of the quadriceps and gluteus medius muscles during different open and closed kinetic chain exercises in women with PPS. Twenty-two clinically healthy women and 24 women with symptomatic PPS were assessed through surface electromyography of the quadriceps and gluteus medius during the following exercises: straight leg raise with and without lateral hip rotation; squats; squats with adduction and hip abduction; and squats combined with lateral hip rotation. When comparing the groups, only the quadriceps muscle showed higher activity in the PPS group. In the comparisons between the exercises, in relation to gluteus medius and quadriceps muscle activity, the straight leg raise and straight leg raise with lateral hip rotation exercises showed more activity than squats in both groups. Among the squats, squats with adduction generated more gluteus medius activity in both groups, and no difference was noted among the squats for the quadriceps muscle. Therefore, rehabilitation programs that include exercises such as straight leg raises, straight leg raises with lateral hip rotation, and squats with adduction may be used for PPS patients.

Heart rate response to graded exercise test of elderly subjects in different ranges of TSH levels

ABSTRACT Objective: Life expectancy is increasing worldwide and studies have been demonstrating that elevated serum thyroid stimulating hormone (TSH) concentration in elderly is associated with some better health outcomes. This elevation is somewhat physiological as aging. The aim of this study was to investigate the heart rate (HR) response during a graded exercise test and its recovery in healthy elderly, comparing subjects within serum TSH in the lower limit of reference range to those within the TSH in the upper limit. Subjects and methods: A cross-sectional study was conducted with 86 healthy elderly aged 71.5 ± 5.1 years, with serum TSH between 0.4 - 4.0 mUl/mL. The participants were divided into two groups according to TSH level: < 1.0 mUl/mL (n = 13) and ≥ 1.0 µUI/mL (n = 73). All participants performed an ergometric test on a treadmill. The HR was recorded and analyzed at rest, during exercise and during the three minutes immediately after exercise. Results: No differences were observed in relation to HR at peak of exercise (TSH < 1.0 µUI/mL: 133.9 ± 22.5 bpm vs. TSH ≥ 1.0 µUI/mL: 132.4 ± 21.3 bpm; p = 0.70) and during the first minute of recovery phase (TSH < 1.0 µUI/mL: 122.3 ± 23.1 bpm vs. TSH ≥ 1.0 µUI/mL: 115.7 ± 18.4 bpm p = 0.33). The groups also presented similar chronotropic index (TSH < 1.0 µUI/mL: 78.1 ± 30.6 vs. TSH ≥ 1.0 µUI/mL: 79.5 ± 26.4; p = 0.74). Conclusion: In this sample studied, there were no difference between lower and upper TSH level concerning HR response during rest, peak of exercise and exercise recovery.

Exercise training improves quality of life in women with subclinical hypothyroidism: a randomized clinical trial.

OBJECTIVE: The aim was to evaluate the quality of life (HRQoL) in women with subclinical hypothyroidism (sHT) after 16 weeks of endurance training. SUBJECTS AND METHODS: In the first phase, a cross-sectional study was conducted in which 22 women with sHT (median age: 41.5 (interquartile range: 175) years, body mass index: 26.2 (8.7) kg/m2, thyroid stimulating hormone > 4.94 mIU/L and free thyroxine between 0.8 and 1.3 ng/dL were compared to a group of 33 euthyroid women concerned to HRQoL. In the second phase, a randomized clinical trial was conducted where only women with sHT were randomly divided into two groups: sHT-Tr (n = 10) - participants that performed an exercise program - and sHT-Sed (n = 10) - controls. Exercise training consisted of 60 minutes of aerobic activities (bike and treadmill), three times a week, for 16 weeks. The HRQoL was assessed by the SF-36 questionnaire in the early and at the end of four months. RESULTS: Women with sHT had lower scores on functional capacity domain in relation to the euthyroid ones (770 ± 23.0 vs. 88.8 ± 14.6; p = 0.020). The sHT-Tr group improved functional capacity, general health, emotional aspects, mental and physical component of HRQoL after training period, while the sHT-Sed group showed no significant changes. CONCLUSION: After 16 weeks of aerobic exercise training, there were remarkable improvements in HRQoL in women with sHT.

Postural control in athletes with different degrees of visual impairment / Controle postural de atletas com diferentes graus de deficiência visual

ABSTRACT The aim of this study was to describe postural control in athletes with different degrees of visual impairment in erect semi-static position and verify whether it differs with sport modalities. Twenty-two athletes with total loss of vision (functional classification B1) and 17 with partial loss of vision (functional classification B2 and B3) were included in this cross-sectional study. Their sport modalities were judo (n = 17), goalball (n = 12) and five-a-side football (n=10). Postural control was investigated on a force platform with athletes in bipedal stance with eyes closed and blindfolded. The elliptical area of 95% confidence interval (mm2) and the mean displacement velocity (mm/s) were calculated. Athletes with total loss of vision presented smaller oscillation area values (p = 0.02) when compared to athletes with partial loss of vision. Considering sport modality, five-a-side athletes were found to present the best postural control. Moreover, goalball athletes oscillated less and presented a lower mean displacement velocity in relation to judoists. The differences found in postural control in visually impaired athletes seem to be associated with the degree of loss of vision and specificities of each sport modality.

RESUMO O objetivo do estudo foi descrever o controle postural na posição ereta semiestática de atletas com diferentes graus de deficiência visual e verificar se existem diferenças de acordo com a modalidade esportiva praticada. Participaram deste estudo seccional 22 atletas com perda total da visão (classificação funcional B1) e 17 com baixa visão (classificação funcional B2 e B3) das modalidades judô (n=17), goalball (n=12) e futebol de cinco (n=10). O controle postural foi investigado utilizando uma plataforma de força, sendo calculadas a área da elipse de 95% de intervalo de confiança (mm2) e a velocidade média de deslocamento (mm/s). A tarefa postural foi realizada com os pés unidos e olhos fechados e vendados. Atletas com perda total da visão apresentaram menores valores para área de oscilação (p=0,02) em relação aos atletas com baixa visão. Na comparação quanto à modalidade esportiva, foi possível observar que os atletas de goalball oscilaram menos e apresentaram menor velocidade de deslocamento que os atletas de judô. Em paralelo, os jogadores de futebol de cinco foram aqueles que apresentaram melhor controle postural. As diferenças encontradas no controle postural de atletas com deficiência visual parecem estar associadas ao grau de perda visual e às especificidades das modalidades esportivas.

Does low serum TSH within the normal range have negative impact on physical exercise capacity and quality of life of healthy elderly people?

Objective Investigate the differences in cardiopulmonary (CP) capacity and Quality of Life (QOL) between healthy elderly (≥ 65 years) with different TSH levels (< 1.0 and ≥ 1.0 μIU/mL) both within the normal range. Also, evaluate the effects of TSH elevation on CP test and QOL, by administering methimazole to subjects with initial lower-normal TSH, in order to elevate it to superior-normal limit. Materials and methods Initially, a cross-sectional study was performed to compare CP capacity at peak exercise and QOL (using WHOQOL-OLD questionnaire) between healthy seniors (age ≥ 65 years) with TSH < 1.0 μIU/mL vs. TSH ≥1.0 μIU/mL. In the second phase, participants with TSH < 1.0 μIU/mL were included in a non-controlled-prospective-interventional study to investigate the effect of TSH elevation, using methimazole, on QOL and CP capacity at peak exercise. Results From 89 elderly evaluated, 75 had TSH ≥ 1 μIU/mL and 14 TSH < 1 μIU/mL. The two groups had similar basal clinical characteristics. No difference in WHOQOL-OLD scores was observed between groups and they did not differ in terms of CP function at peak exercise. QOL and CP variables were not correlated with TSH levels. Twelve of 14 participants with TSH < 1.0 μIU/mL entered in the prospective study. After one year, no significant differences in clinical caracteristics, QOL, and CP variables were detected in paired analysis before and after methimazole intervention. Conclusions We found no differences in CP capacity and QOL between health elderly with different TSH levels within normal range and no impact after one year of methimazole treatment. More prospective-controlled-randomized studies are necessary to confirm or not the possible harm effect in normal low TSH.

Does low-normal serum TSH level adversely impact cognition in elderly adults and might methimazole therapy improve outcomes?

Serum thyroid stimulating hormone (TSH) levels increase with age. This elevation has been associated with better outcomes in very elderly subjects; however, little is known about the relationship between TSH below the lower limit of the reference range and health-related outcomes. Here, we investigated the association between cognitive impairment or depressive symptoms and low-normal serum TSH (<1.0 µIU/mL, in the reference range) in elderly subjects and whether the use of methimazole in subjects without dementia but with low-normal TSH could affect cognition or depressive symptoms. From 293 healthy adults ≥65 years old with normal TSH included in the sectional phase, only subjects without dementia were prospectively analyzed: 1) TSH ≥1.0 µIU/mL (observation; untreated); 2) TSH <1.0 µIU/mL (observation; untreated); and 3) TSH <1.0 µIU/mL (methimazole therapy). Cognition was assessed, using the Mini Mental State Examination (MMSE) and depressive symptoms (at MMSE ≥ 13) by the Geriatric Depression Scale (GDS). Age >80 years was the sole independent factor associated with dementia (OR=2.89; confidence interval [CI] 1.72-4.86; p<0.01). Prospectively, 93 completed follow-up, with 7.5% (7) receiving methimazole intervention. Untreated subjects with lower TSH showed the greatest declines in MMSE scores during follow-up that was not observed in those with serum TSH ≥1.0 µIU/mL. Lower MMSE score reductions were associated with elderly subjects receiving methimazole. There were no significant changes in depressive symptoms and GDS scores among those with serum TSH <1.0 µIU/mL. In this study, low-normal TSH was not associated with higher prevalence of dementia. However, in elderly subjects without dementia, low TSH was associated with worsening cognition.

Does low serum TSH within the normal range have negative impact on physical exercise capacity and quality of life of healthy elderly people?

OBJECTIVE: Investigate the differences in cardiopulmonary (CP) capacity and Quality of Life (QOL) between healthy elderly (≥ 65 years) with different TSH levels (< 1.0 and ≥ 1.0 µIU/mL) both within the normal range. Also, evaluate the effects of TSH elevation on CP test and QOL, by administering methimazole to subjects with initial lower-normal TSH, in order to elevate it to superior-normal limit. MATERIALS AND METHODS: Initially, a cross-sectional study was performed to compare CP capacity at peak exercise and QOL (using WHOQOL-OLD questionnaire) between healthy seniors (age ≥ 65 years) with TSH < 1.0 µIU/mL vs. TSH ≥1.0 µIU/mL. In the second phase, participants with TSH < 1.0 µIU/mL were included in a non-controlled-prospective-interventional study to investigate the effect of TSH elevation, using methimazole, on QOL and CP capacity at peak exercise. RESULTS: From 89 elderly evaluated, 75 had TSH ≥ 1 µIU/mL and 14 TSH < 1 µIU/mL. The two groups had similar basal clinical characteristics. No difference in WHOQOL-OLD scores was observed between groups and they did not differ in terms of CP function at peak exercise. QOL and CP variables were not correlated with TSH levels. Twelve of 14 participants with TSH < 1.0 µIU/mL entered in the prospective study. After one year, no significant differences in clinical caracteristics, QOL, and CP variables were detected in paired analysis before and after methimazole intervention. CONCLUSIONS: We found no differences in CP capacity and QOL between health elderly with different TSH levels within normal range and no impact after one year of methimazole treatment. More prospective-controlled-randomized studies are necessary to confirm or not the possible harm effect in normal low TSH.

Association Between Hemodynamic Profile, Physical Capacity and Quality of Life in Pulmonary Hypertension / Associação Entre Perfil Hemodinâmico, Capacidade Física e Qualidade de Vida na Hipertensão Pulmonar

Background: No studies have described and evaluated the association between hemodynamics, physical limitations and quality of life in patients with pulmonary hypertension (PH) without concomitant cardiovascular or respiratory disease. Objective: To describe the hemodynamic profile, quality of life and physical capacity of patients with PH from groups I and IV and to study the association between these outcomes. Methods: Cross-sectional study of patients with PH from clinical groups I and IV and functional classes II and III undergoing the following assessments: hemodynamics, exercise tolerance and quality of life. Results: This study assessed 20 patients with a mean age of 46.8 ± 14.3 years. They had pulmonary capillary wedge pressure of 10.5 ± 3.7 mm Hg, 6-minute walk distance test (6MWDT) of 463 ± 78 m, oxygen consumption at peak exercise of 12.9 ± 4.3 mLO2.kg-1.min-1 and scores of quality of life domains < 60%. There were associations between cardiac index (CI) and ventilatory equivalent for CO2 (r=-0.59, p <0.01), IC and ventilatory equivalent for oxygen (r=-0.49, p<0.05), right atrial pressure (RAP) and 'general health perception' domain (r=-0.61, p<0.01), RAP and 6MWTD (r=-0.49, p<0.05), pulmonary vascular resistance (PVR) and 'physical functioning' domain (r=-0.56, p<0.01), PVR and 6MWTD (r=-0.49, p<0.05) and PVR index and physical capacity (r=-0.51, p<0.01). Conclusion: Patients with PH from groups I and IV and functional classes II and III exhibit a reduction in physical capacity and in the physical and mental components of quality of life. The hemodynamic variables CI, diastolic pulmonary arterial pressure, RAP, PVR and PVR index are associated with exercise tolerance and quality of life domains. .

Functional Capacity of Oldest Old Living in a Long-stay Institution in Rio De Janeiro, Brazil.

[Purpose] A significant increase in the number of oldest old has occurred worldwide. The aim of this study was to characterize the functional capacity of the oldest old residents in a long-stay institution in Rio de Janeiro, Brazil. [Subjects and Methods] All participants were evaluated according to the following metrics: anthropometry, body composition (bioelectrical impedance), handgrip strength, balance (Berg scale and stabilometry), ankle mobility (electrogoniometry), physical capacity (six-minute walk test), quality of life (WHOQOL-OLD), and dietary habits (questionnaire). [Results] Twenty elderly subjects with a mean age of 85.75 ± 5.22 years and a mean fat percentage of 39.02 ± 5.49% participated in the study. The group at risk of falls (n = 8) had a lower handgrip strength and walked a shorter distance over the course of six minutes compared with the group not at risk of falls. The obese group (n = 15) had higher values for stabilometric variables than the nonobese group. There was a positive and significant correlation between ankle joint mobility and physical capacity (r = 0.47). [Conclusion] High values for obesity and low values for handgrip strength and physical capacity were associated with worse body balance. Low values for ankle mobility were also associated with worse physical capacity in this population.

INTRODUCTION: Sports training in various modalities is associated with injuries, especially when presenting large volume and intensity. Few Brazilian studies have investigated the prevalence of injury in tennis players, however, information about the location, type and mechanisms injuries which affect this group of athletes are important for prevention and treatment of such injuries. OBJECTIVE: To determine the frequency of lesions reported by amateur tennis players in the city of Rio de Janeiro. METHODS: The evaluation was conducted through a structured questionnaire with information about the affected body region, type and mechanism of injury, as well as data on the characteristics of the training. The groups formed, injury and non injury, were compared by Student's t test or Mann-Whitney test, and the chi-squared or Fisher's exact test, using SPSS software (p<0.05). RESULTS: Of 159 tennis players (89.3% men, 45.3±11.4 years old; 8.5±6.6 years of tennis practice) which completed the questionnaire, 38.4% reported having been affected by an injury arising from tennis. The most affected regions were: elbow (24.5%), knee (11.3%), and ankle (6.9%). Considering all injuries, tendinitis was the most frequently reported (24.5%), followed by sprain (12.6%) and meniscal injuries (4.4%). Regarding the mechanism of injury, the most prevalent were repetition (25.2%) and changes of direction (15.1%). The injury group presented higher age (48.8±10.1 vs. 43.6±11.8 years), years of tennis practice (10.5±8.5 vs. 7.2± 4.8), and total body mass (86.8±9.8 vs. 81.0±11.0kg). CONCLUSION: The prevalence of injuries in amateur tennis players in Rio de Janeiro was 38.4%, being lateral epicondylitis of the elbow the most frequent, due to the repetition of the characteristic motor actions of this sport. .
