Fibromyalgia (FM) is recognized as a common condition, characterized by widespread pain and associated with sleep disturbances and poor-quality sleep. The Pittsburgh Sleep Questionnaire Index (PSQI) is one of the most recommended instruments to measure sleep quality and sleep disorders. The purpose of our study was to translate the questionnaire into Spanish and to assess the psychometric properties of the Spanish version of the PSQI. A total of 138 women with FM belonging to a FM association (AFIXA, Andalusia, Spain) completed the study. Internal consistency and test-retest reliability were analyzed. Factorial analysis was performed for the PSQI components. Convergent validity of the PSQI was evaluated using Spearman's rank correlation coefficient with the Spanish versions of the Fibromyalgia Impact Questionnaire (FIQ) and the health survey short form-36 (SF-36). In our analysis, the Spanish version of the PSQI has shown a good internal consistency of the total score, with a Cronbach's alpha of 0.805, and an acceptable test-retest reliability, with a Spearman's correlation coefficient of 0.773 (p < 0.001), for the total score. A two-factor structure was generated by exploratory factor analysis, with a Cronbach's alpha of 0.866 for factor 1 and of 0.712 for factor 2. In convergent validity analysis, the PSQI total score showed a significant correlation (p < 0.01) with the FIQ total score and with the mental and physical health summaries scores of the SF-36. Our results show that the Spanish version of the PSQI provides a reliable instrument, with a good convergent validity for measuring sleep quality among Spanish FM patients.

The objective of the present study was to determine the effectiveness of a 6-week balance training program on patients with Chronic Ankle Instability (CAI) in relation to the results obtained in Dynamic Balance, subjective feeling of instability and pain using a single-blind randomized controlled trial. 70 athletes were randomly assigned to control or intervention group. The control group performed their usual training, and the intervention group was administered the same usual activity in addition to a balance program. The paired t-test was performed to evaluate the change scores in each group. The t-test for independent samples was performed to evaluate between-group differences in change scores. Significance level was assigned for p-values less than 0.05 for all analyses. There were significant differences between groups in change scores in CAIT and all of the SEBTs reach distances (p<0.001) but not in Pain (p=0.586). The effect sizes were larger for the outcomes measures that showed significant differences. In the within-group change, the experimental groups showed larger effect sizes in CAIT, SEBT posteromedial and SEBT posterolateral, and moderate effect sizes in SEBT anterior. Exercise therapy training based on multi-station balance tasks led to significant improvements in dynamic balance and self-reported sensation of instability in patients with CAI.

This study aimed to evaluate the effects of a 12-week high-intensity interval exercise (HIIT) training program involving suspension exercises (TRX) on the muscle strength, body composition, gait speed, and quality of life of older adults. A total of 82 older adults were randomly assigned to 3 groups: a HIIT group (n=28), a continuous intensity training group (MIIT group, n=27), or a control group (CG, n=27). Compared to MIIT and CG, participants of the HIIT group showed significant post-intervention improvements in BMI (p=.002 and p<.001, respectively) and gait speed (p<.001 for both). Handgrip strength increase was also observed after HIIT (p=.002), but no differences were observed with MIIT and CG. Compared with MIIT and control groups, HIIT showed improvements in the SF-36 domains: general health (p<.001 for both) health changes (p<.001 for both), vitality (p=.002 and p=.001 respectively) and physical functioning (p=.036 and p<.001 respectively). Our results suggest that a HIIT training program with TRX have benefits in BMI, handgrip strength, gait speed, and quality of life in older adults.

Joint mobilization techniques applied to subjects suffering from CAI were able to improve ankle DFROM, postural control, and self-reported instability. These results suggest that joint mobilization could be applied to patients with recurrent ankle sprain to help restore their functional stability. Implications for Rehabilitation Functional instability is a very common sequela in patients with CAI, resulting in reduced quality of living due to the limitations it imposes on daily life activities. The mobilization with movement technique presented by Mulligan, and based on the joint mobilization accompanied by active movement, appears as a valuable tool to be employed by physical therapists to restore ankle function after a recurrent ankle sprain history. ROM restriction, subjective feeling of instability and dynamic postural control are benefiting from the joint mobilization application.

EXE alone and EXE-SUPPL improved muscle-related outcomes and reduced fat-related outcomes in subjects with sarcopenic obesity. There is a need for better-designed RCTs with systematic assessment of both different exercise regimes and dietary supplements in sarcopenic obese subjects.

The purpose of this study was to determine the effects of a 12-week contrast training (CT) program (isometric + plyometric), with no external loads, on the vertical jump, kicking speed, sprinting, and agility skills of young soccer players. Thirty young soccer players (age, 15.9 ± 1.43 years; weight, 65.4 ± 10.84 kg; height, 171.0 ± 0.06 cm) were randomized in a control group (n = 13) and an experimental group (n = 17). The CT program was included in the experimental group's training sessions, who undertook it twice a week as a part of their usual weekly training regime. This program included 3 exercises: 1 isometric and 2 plyometric, without external loads. These exercises progressed in volume throughout the training program. Performance in countermovement jump (CMJ), Balsom agility test (BAT), 5-, 10-, 20-, and 30-m sprint, and soccer kick were assessed before and after the training program. A 2-factor (group and time) analysis of variance revealed significant improvements (p < 0.001) in CMJ, BAT, and kicking speed in the experimental group players. Control group remained unchanged in these variables. Both groups significantly reduced sprint times over 5, 10, 20, and 30 m (p ≤ 0.05). A significant correlation (r = 0.492, p < 0.001) was revealed between ΔBAT and Δaverage kicking speed. Results suggest that a specific CT program without external loads is effective for improving soccer-specific skills such as vertical jump, sprint, agility, and kicking speed in young soccer players.
