ABSTRACT
BACKGROUND: The aim of this study was to analyze the strength status of the rectus abdominis muscle in patients with incisional hernia and the relationship between the width of the hernia defect and the strength of the rectus abdominis muscle. METHODS: This is a observational cohort study of patients with medial line incisional hernia (July-October 2022), classified as W2 according to the European Hernia Society (EHS). The data collected were demographic and clinical characteristics related to hernia, and measure of the rectus abdominis muscle strength using an isokinetic dynamometer and a strain gauge. We analyzed the relationship between hernia width and rectus abdominis muscle strength with correlation tests to adjustment by age, sex, BMI, and body composition. RESULTS: A total of 40 patients (64% female) with a mean age of 57.62 years (SD 11) were enrolled in the study. The mean BMI was 29.18 (SD 5.06), with a mean percentage of fat mass of 37.8% (SD 8.47) and a mean percentage of muscle mass of 60.33% (SD 6.43). The maximum width of the hernia defect was 6.59 cm (SD 1.54). In the male group, the mean bending force moment (ISOK_PT) was 94.01 Nw m (SD 34.58), bending force moment relative to body weight (ISOK_PT_Weight) was 103.32 Nw m (SD 37.48), and peak force (PK_90) was 184.71 N (SD 47.01). In the female group, these values were 58.11 Nw m (SD 29.41), 66.48 Nw m (SD 32.44), and 152.50 N (SD 48.49), respectively. Statistically significant differences were observed in the relationship between the data obtained with the isokinetic dynamometer and sex (p = 0.002), as well as between the data obtained with the isokinetic dynamometer and age (p = 0.006). Patients in the 90th percentile (P90) of rectus abdominis muscle strength also had smaller hernia defect widths (p = 0.048). CONCLUSIONS: In this study, age and sex were identified as the most statistically significant predictor variables for rectus abdominis muscle strength. The width of the hernia defect exhibited a trend towards statistical significance.

BACKGROUND: The purpose of this study is the evaluation of the patellofemoral arthroplasty (PFA) survival and clinical and radiological outcomes in our institution. METHODS: A retrospective evaluation of our institution patellofemoral arthroplasty cases from 2006 to 2018 was performed; the n sample after applying exclusion and inclusion criteria was 21. All patients excepting one were female with a median age of 63 (20-78). A Kaplan-Meier survival analysis at ten years was calculated. Informed consent was obtained from all patients prior being included in the study. RESULTS: The total revision rate was 6 out of 21 patients (28.57%). The progression of the osteoarthritis in the tibiofemoral compartment was the main cause (50% of revision surgeries). The degree of satisfaction with the PFA was high, with a mean Kujala score of 70.09 and a mean OKS of 35.45 points. The VAS score improved significantly (P<.001) from a preoperative mean of 8.07 to a postoperative mean of 3.45, with an average improvement of 5 (2-8). Survival at 10 years, with revision for any reason as the endpoint, was 73.5%. A significant positive correlation between BMI and the WOMAC pain (r=.72, P<.01) and between BMI and the post-operative VAS (r=.67, P<.01) was observed. CONCLUSIONS: The results of the case series under consideration suggest that PFA could be a possibility in the joint preservation surgery on the isolated patellofemoral osteoarthritis. BMI >30 seems to be a negative predictor factor in relationship with the postoperative satisfaction, increasing the pain proportionally to this index and requiring more replacement surgery than patients with BMI <30. Meanwhile the radiologic parameters of the implant are not correlated with the clinical or functional outcomes.

ABSTRACT
Osteoporosis is a major health issue worldwide. This study analyzes the effects of non-supervised osteoporosis prevention programs on bone mineral density. Non-supervised exercise increases femoral neck and lumbar spine bone mineral density in adult women. Thus, it might be effective for preventing or treating osteoporosis or osteopenia in this population. INTRODUCTION: Osteoporosis is a major health issue worldwide. Social distancing measures due to COVID-19 have hindered the chances to take part in supervised osteoporosis prevention exercise programs. The purpose of the present study is to systematically review and meta-analyze the effects of non-supervised osteoporosis prevention exercise programs on bone mineral density (BMD) in adult women. METHODS: A comprehensive search of electronic databases (n = 7) was conducted including (a) prospective randomized controlled trials (RCTs) comparing at least one exercise group vs. a control group with sedentary lifestyle or sham exercises; (b) baseline and follow-up BMD values, or BMD changes from baseline, at any skeletal site; (c) women over 30 years old; and (d) non-supervised exercise programs only. Subgroup analyses were performed for menopausal status, intervention duration, type of exercise, and osteopenia/osteoporosis status. RESULTS: Ten studies were included (n = 668). Random effect analyses showed that unsupervised exercise had beneficial effects on lumbar spine (LS) BMD with standardized mean difference (SMD) = 0.40 (95% confidence interval (CI): 0.03-0.77), and femoral neck (FN) BMD with SMD = 0.51 (95% CI: 0.16-0.85). Unsupervised exercise increased LS (SMD = 0.73 (95% CI: 0.13-1.33)) and FN BMD (SMD = 0.85 (95% CI: 0.33-1.37)) in women with osteopenia/osteoporosis, but not in healthy counterparts. CONCLUSION: Non-supervised exercise improves FN and LS BMD in adult women. Beneficial effects of exercise on FN and LS BMD might be more pronounced in those with poor bone health compared with healthy counterparts. More RCTs prescribing non-supervised, osteogenic exercise are required in this population. It is necessary to investigate the efficacy of remote/assistive technologies for delivering and monitoring non-supervised exercise interventions.

Fibromyalgia syndrome (FMS) is a common and complex chronic pain condition. Exercise is recommended in the management of the FMS; however, people with FMS often find exercise exacerbates their condition and causes overwhelming fatigue. The objective of this study was to explore the perceptions of fatigue and sleep dysfunction, and exercise in people with FMS. Three, 60-90 min focus groups were conducted with people with FMS (n = 14). Participants were recruited from patient support groups who had experienced therapeutic exercise in the management of their condition. Focus groups were video and audio recorded and transcriptions analysed for thematic content by three independent evaluators. Fatigue, sleep dysfunction, and pain were universally reported by participants. The over-arching theme to emerge was a lack of understanding of the condition by others. A huge sense of loss was a major sub-theme and participants felt that they had fundamentally changed since the onset of FMS. Participants reported that they were unable to carry out their normal activities, including physical activity and exercise. The invisibility of FMS was associated with the lack of understanding by others, the sense of loss, and the impact of FMS. People with FMS perceive that there is a lack of understanding of the condition among health care professionals and the wider society. Those with FMS expressed a profound sense of loss of their former 'self'; part of this loss was the ability to engage in normal physical activity and exercise.

The aims of this study were to analyse the effects of eccentric overload training (EOT) on kinetic parameters during change of direction (COD) and performance related to sprinting and jumping abilities. 20 male soccer players performed 2 different protocols: 1) 5-min cycling warm-up and 2) 5-min cycling warm-up+YoYo half-squat exercise. The outcome measured included vertical ground reaction force (vGRF) and propulsive force (PvGRF), time to vGRF (T_vGRF) and propulsive force (T_PvGRF), contact time (CT), eccentric (ECC_IMP), concentric (CONC_IMP) and total (TOT_IMP) impulses and moments (Mx, My and Mz) during 2 COD tasks. Additionally, subjects performed a counter-movement jump (CMJ) and 20 m sprint tests. Results showed a substantial better improvement (likely to almost certainly) in vGRF (ES: 0.84), vAGRF (ES: 0.72), CT (ES: 0.48), My (ES: 0.35), Mz (ES: 0.44) and ECC_IMP (ES: 0.45) during crossover cutting maneuver, whereas during side-step cutting maneuver Time_ECC (ES: 0.68), CT (ES: 0.64), vGRF (ES: 0.48) and My (ES: 0.47) were substantially enhanced (likely). Furthermore, substantial better performance was found in CMJ (ES: 0.47; very likely) and 20 m (ES: 0.20; possibly). In conclusion, EOT produced a better muscle activation during 2 different COD tasks and greater sprinting and jumping performance.

OBJECTIVE: To examine the effect of passive whole-body vibration (WBV) on heart rate (HR) variability (HRV) during the recovery from intense exercise. DESIGN: Randomized, counterbalanced, crossover design SETTING: Laboratory. INTERVENTIONS: Twenty-three healthy male performed a bicycle exercise test to exhaustion followed by an active recovery period using WBV (25Hz and peak to peak displacement of 4mm) or passive recovery period (noWBV; 0Hz-0mm) on two separate days in random order. The recovery protocol consisted of six 1-min sets separated by 1-min inter-set rest periods in the seated position with the feet on the vibration platform. ECG recordings were made at baseline and during recovery at min 2, 4, 6, 8, 10 and 12 in both conditions. Frequency-domain measures of HRV were determined via power spectral analysis using fast-Fourier transform. Low frequency (LF; 0.04-0.15Hz) and high frequency bandwidths (HF; 0.15-0.4Hz) were determined. RESULTS: HR was increased in both groups (P<0.01) throughout the recovery. At min 2, HR was lower (P=0.05) after WVB compared to the noWBV trial. At min 3, the increase (P<0.05) in total power after WBV was significantly different (P<0.01) compared to noWBV. Normalized (nu) LF and LF/HF were increased (P<0.01), whereas HF nu was reduced (P<0.001) in both conditions without a significant group-by-time interaction (P=0.08). CONCLUSION: Passive WBV reduces HR and increases total power during the early recovery of intense exercise, despite no effect on power spectral components of HRV.

OBJECTIVE: To explore the relationship between nutritional status, functional capacity and health-related quality of life (HRQoL) in older adults with type 2 diabetes (T2DM). DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: Forty two non-insulin dependent older adults from a primary care center in Seville, Spain. MEASUREMENTS: Function was assessed with a battery of standardized physical fitness tests. Nutritional status was assessed using the Mini Nutritional Assessment (MNA) and the European Quality of Life Questionnaire (EQ-5D-3L) was used to assess HRQoL. RESULTS: There was an association between MNA-nutritional status and lower body strength as assessed by the chair sit-stand test (rho= .451; p= .037) and between MNA-nutritional status and EQ-5D-3L-HRQoL (EQ-5D-3Lutility, rho= .553; p<.001 and EQ-5D-3LVAS rho= .402; p<.001). An MNA item by item correlation analysis with HRQoL and lower limb strength demonstrated that HRQoL appears to be related to functional capacity (principally lower body strength, motor agility and cardiorespiratory fitness) among participants. These results were maintained when correlations were adjusted for co-morbidity. CONCLUSION: Our results demonstrated that nutritional status is moderately associated with HRQoL and lower limb strength in patients with T2DM. Our data suggest that more emphasis should be placed on interventions to encourage a correct diet and stress the needed to improve lower body strength to reinforce better mobility in T2DM population.

OBJECTIVES: The aim of this study was to investigate the effectiveness of a 6-week traditional exercise programme with supplementary whole-body vibration (WBV) in improving strength and health status in women with fibromyalgia (FM). METHODS: Thirty postmenopausal women with FM (mean (SD) age: 59 (7.90) years) were randomised into one of two groups, one intervention group (GEV n=15), which combined exercise training (two days a week) with three days of WBV (3 sets of 45 s at 20 Hz-3 mm and four sets of unilateral static squats at 20 Hz-2 mm) and another control group (n=15), that performed the same physical activity programme but without vibration training (GEnV). The Fibromyalgia Impact Questionnaire (FIQ) and the global score of the SF-36 were used to assess functional capacity and quality of life. Two additional tests were employed to assess muscle strength. Baseline data and pre-test and post-test data were collected before and after the six-week intervention period. RESULTS: Significant improvements in all outcomes measured were found from baseline in both groups. A 5% improvement from baseline in total FIQ score was observed in the exercise groups (p≤0.05), and was accompanied by reductions in SF36 scores of 9.8% (p<0.001) and 7.9% (p<0.001) in the GEV and GEnV group, respectively. Improvements were also observed in muscle strength in both groups but greater in the GEV group. CONCLUSIONS: The results suggest that women with FMS can gain additional health benefits by engaging in a 6-week traditional exercise programme with supplementary WBV.

OBJECTIVES: This study has two main aims, firstly to define subgroups of women affected by fibromyalgia syndrome (FMS) based on symptoms and secondly to determine cardiovascular parameters in treadmill exercises in order to prescribe physical activity. METHODS: Thirty-two women (age= 53.26+/-6.61 yr) were assigned to two different groups based on their functional capacity and symptoms as measured by the Fibromyalgia Impact Questionnaire and pain. Subjects were submitted twice to a maximum treadmill incremental test until participants achieved volitional exhaustion (VO2max). Expired respiratory gases, ventilator parameters and heart rate (HR) were measured continuously through exercise, and rate perceived exertion (RPE) was assessed once a minute during the test. RESULTS: Peak VO2 values for the moderately affected group (Group 1) were significantly different from those of severely affected group (Group 2) (26.2+/-2.1 ml x kg(-1) x min(-1) (Group 1) and 22.1+/-2.5 ml x kg(-1) x min(-1) (Group 2)). Additionally taking into account VO2 at ventilatory threshold (VO2VT), significant differences between groups were found in both tests. Some notable differences in all parameters evaluated were also found. CONCLUSION: This study has demonstrated that the aerobic capacity of patients with FMS was different according to how severely affected they were by the condition; therefore, physical activity of the same intensity should not be prescribed for both groups. According to these results, health professionals could prescribe physical activity with confidence to this patient group.
