A evidence-based approach to selecting post-exercise cryostimulation techniques for improving exercise performance and fatigue recovery: A systematic review and meta-analysis.
RATIONALE
Cryostimulation involves using water environments and low temperatures as intervention mediums, with main methods including CWI (cold water immersion), CWT (contrast water therapy), and WBC (whole-body cryostimulation). Previous systematic reviews focused on the effect of cryostimulation on muscle fatigue and sports performance. However, studies on the selection of different cryostimulation methods and their intervention effects present inconsistent results.
INTRODUCTION
To systematically review and methodologically appraise the quality and effectiveness of existing intervention studies that the effects of various cryostimulation methods, including CWI, CWT, and WBC, on exercise performance and fatigue recovery.
METHODS
Following PRISMA guidelines, we conducted searches in PubMed, Embase, The Cochrane Library, Web of Science, and EBSCO databases to gather randomized controlled trials or self-controlled trials involving CWI/CWT/WBC and their effects on exercise performance or fatigue recovery. The search period ranged from November 2013 to November 2, 2023. Literature screening was performed using EndNote X9.1, and the quality of included studies was assessed using the Cochrane risk of bias assessment tool. Meta-analysis was conducted using RevMan 5.3 software.
RESULTS
This study included a total of 18 articles, included a total of 499 healthy participants, comprising 479 males and 20 females. Among them, participants underwent cryostimulation, including 102 using CWT, using CWI, and 58 using WBC. Compared to the control group, cryostimulation can significantly alleviate muscle pain intensity (SMD -0.45, 95% CL -0.82 to 0.09, P = 0.01). Specifically, CWI significantly reduced muscle pain intensity (SMD = -0.45, 95% CI: 0.820.09, P = 0.01), WBC significantly decreased C-reactive protein levels (SMD = -1.36, 95% CI: 2.350.36, P = 0.008). While, CWT showed no significant differences from the control group in exercise performance and fatigue recovery indicators (P > 0.05).
CONCLUSION
Cryostimulation can significantly reduce muscle pain intensity and perceived fatigue. Specifically, CWI significantly alleviates muscle pain intensity, WBC significantly lowers markers of inflammation caused by fatigue after exercise, in contrast, CWT does not significantly improve exercise performance and fatigue recovery. After exercise, compared with rest, using cryostimulation may have more noticeable benefits for muscle fatigue and muscle pain, with recommendations prioritizing WBC and CWI particularly for addressing inflammation and muscle pain. However, all cryostimulation may have no significant influence on exercise performance.

Review
BACKGROUND
Handgrip strength (HGS) is an indicator of muscular strength, used in the diagnosis of sarcopenia, undernutrition, and physical frailty as well as recovery. Typically, the maximum HGS value is used; however, recent evidence suggests the exploration of new indicators provided based on the force-time curve to achieve a more comprehensive assessment of muscle function. Therefore, the objective was to identify indicators of the HGS profile beyond maximum HGS, based on force-time curves, and to systematize knowledge about their applications to various types of samples, health issues, and physical performance.
METHODS
A systematic review was performed including studies whose participants' HGS was assessed with a digital or adapted dynamometer. The outcome measures were HGS profile indicators calculated from the force-time curve.
RESULTS
a total of 15 studies were included, and the following indicators were identified: grip fatigue, fatigability index, fatigue rate, fatigue resistance, time to 80% maximal voluntary contraction, plateau coefficient of variability, time to maximum value, T-90%, release rate, power factor, grip work, average integrated area, endurance, cycle duration, time between cycles, maximum and minimum force-velocity, rate of grip force, final force, inflection point, integrated area, submaximal control, and response time.
CONCLUSIONS
Various indicators based on the force-time curve can be assessed through digital or adapted dynamometers. Future research should analyze these indicators to understand their implications for muscle function assessment, to standardize evaluation procedures, to identify clinically relevant measures, and to clarify their implications in clinical practice.

Review
Cancer is associated with increased muscle weakness, reduced physical functioning, increased fatigue, but also sleep disturbances, including insomnia, that affect quality of life (QoL). Physical activity demonstrated benefits on functional capacity, resilience and cancer-related fatigue, but there is a paucity of available data regarding its effects on insomnia in patients with cancer. This systematic review aims to examine the efficacy of exercise levels with insomnia in cancer patients. A systematic search was performed for articles published in PubMed and Cochrane Library databases from December 2013 to February 2023. Included studies explored insomnia during or after cancer treatment, with various exercise interventions. The search identified nine studies included in this review. Due to substantial heterogeneity in the interventions across studies, meta-analysis was not performed. Three studies reported positive results for insomnia reduction by self-reported outcomes under a supervised aerobic exercise program alone or combined with strength training. The present systematic review establishes the role of exercise interventions for reducing cancer-related insomnia. Further studies are indeed warranted to improve the level of evidence for exercise interventions for implementation in the care of cancer-related insomnia.

Effect of Telerehabilitation on Pulmonary Function, Functional Capacity, Physical Fitness, Dyspnea, Fatigue, and Quality of Life in COVID-19 Patients: A Systematic Review and Metanalysis.
This study aimed to demonstrate the technological means used to offer telerehabilitation and to evaluate the effect of physical exercise on the population affected by COVID-19. Clinical trials were searched in the electronic databases Cochrane Library, PubMed/MEDLINE, EBSCO (CINAHL), PEDro, and Web of Science from January 16 to 19, 2023. The effect measure was estimated as mean difference (MD) or standard MD (SMD) with 95% confidence intervals (CI). Subgroup analysis was used to study potential moderating factors. Twenty-four articles, describing trials with a total of 1,344 individuals affected by COVID-19, were included in the qualitative synthesis and 14 articles in the meta-analysis. The pooled results revealed that telerehabilitation improves the functional capacity (MD 79.65 [63.57, 95.73]m, < 0.00001), agility (MD -0.69 [-1.33, -0.04] s, = 0.04), lower limb strength and endurance (SMD 0.74 [0.52, 0.96], < 0.00001), forced expiratory volume in 1 s (MD 0.22 [-0.04, 0.49] L, = 0.10), and dyspnea (SMD -0.94 [-1.64, -0.24], = 0.009). The dynamic muscular resistance training associated or not with other exercise modalities led to improvements in muscular strength (MD 4.69 [0.44, 8.94] kg, = 0.03) and fatigue (SMD -0.97 [-1.74, -0.20], = 0.01). In addition, telerehabilitation showed improvements in the quality of life in the contagious-phase COVID-19 patients. Although this intervention improved inspiratory muscle strength (MD 13.71 [5.41, 22.0] cmHO, = 0.001), it did not favor forced vital capacity. Telerehabilitation contributed to improving functional capacity, inspiratory muscle strength, physical fitness, and quality of life, and reducing dyspnea and fatigue in COVID-19 adult survivors.

Review
CONTEXT
Movement velocity (MV) may be a valid tool to evaluate and control the load in resistance training (RT). The rating of perceived exertion (RPE) also enables practical load management. The relationship between RPE and MV may be used to monitor RT intensity.
OBJECTIVE
To evaluate the validity and practicality of RPE scales related to MV and training intensity in resistance exercise. We hypothesize a positive correlation among RPE, MV, and load intensity in RT. Therefore, RPE may serve as a supplementary indicator in monitoring RT load.
DATA SOURCES
Boolean algorithms were used to search several databases (SPORTDiscus, EBSCO, PubMed, Scopus, and Google Scholar).
STUDY SELECTION
Studies published from 2009 to 2023 included clinical trials (randomized or not) in healthy female and male subjects that analyzed the relationship between different RPE scales and MV in basic RT exercises.
STUDY DESIGN
Systematic review.
LEVEL OF EVIDENCE
Level 3.
RESULTS
A total of 18 studies were selected using different RPE scales with reported MV training loads. Participants included RT and untrained male and female subjects (15-31 years old). Two RPE scales (OMNI-RES and repetitions in reserve) were used. The selected studies showed moderate positive correlations among these RPE scales, MV, and training load (eg, percentage of 1-repetition maximum [%1-RM]). In addition, equations have been developed to estimate %1-RM and MV loss based on the OMNI-RES scale.
CONCLUSION
Studies show that RPE scales and MV constitute a valid, economic, and practical tool for assessing RT load progression and complementing other training monitoring variables. Exercise professionals should consider familiarizing participants with RPE scales and factors that might influence the perception of exertion (eg, level of training, motivation, and environmental conditions).

BACKGROUND
Physical exertion during exercise often leads to increased oxidative stress and inflammatory responses, significantly affecting physical performance. Current strategies to mitigate these effects are limited by their effectiveness and potential side effects. Molecular hydrogen (H₂) has gained attention for its antioxidant and anti-inflammatory properties. Studies have suggested that H supplementation contributes to antioxidant potential and anti-fatigue during exercise, but the variance in the observations and study protocols is presented across those studies.
OBJECTIVE
This systematic review and meta-analysis aimed to comprehensively characterize the effects of H₂ supplementation on physical performance (i.e., endurance, muscular strength, and explosive power), providing knowledge that can inform strategies using H for enhancing physical performance.
METHODS
We conducted a literature search of six databases (PubMed, Web of Science, Medline, Sport-Discus, Embase, and PsycINFO) according to the PRISMA guidelines. The data were extracted from the included studies and converted into the standardized mean difference (SMD). After that, we performed random-effects meta-analyses and used the statistic to evaluate heterogeneity. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess the quality of the evidence obtained from this meta-analysis.
RESULTS
In total, 27 publications consisting of 597 participants were included. The search finally included aerobic endurance, anaerobic endurance, muscular strength, lower limb explosive power, rating of perceived exertion (RPE), blood lactate (BLA), and average heart rate (HR) in the effect size (ES) synthesis. The ES of H on aerobic endurance, including V̇O (SMD = 0.09, = 0.394; = 0%) and aerobic endurance exercise (SMD = 0.04, = 0.687; = 0%), were not significant and trivial; the ES of H on 30 s maximal anaerobic endurance (SMD = 0.19, = 0.239; = 0%) was not significant and trivial; the ES of H on muscular strength (SMD = 0.19, = 0.265; = 0%) was not significant and trivial; but the ES of H on lower limb explosive power (SMD = 0.30, = 0.018; = 0%) was significant and small. In addition, H reduces RPE (SMD = -0.37, = 0.009; = 58.0%) and BLA (SMD = -0.37, = 0.001; = 22.0%) during exercise, but not HR (SMD = -0.27, = 0.094; = 0%).
CONCLUSION
These findings suggest that H supplementation is favorable in healthy adults to improve lower limb explosive power, alleviate fatigue, and boost BLA clearance, but may not be effectively improving aerobic and anaerobic endurance and muscular strength. Future studies with more rigorous designs are thus needed to examine and confirm the effects of H on these important functionalities in humans.

Review
BACKGROUND
The term "post-COVID-19 condition" refers to the symptomatology that appears between four to twelve weeks after Covid-19 infection. These symptoms can persist for weeks or even months, significantly diminishing the quality of life for affected individuals. The primary objective of this study was to assess the effectiveness of pulmonary rehabilitation programs and/or respiratory muscle training on respiratory sequelae in patients with post-COVID condition.
METHODS
The literature search was conducted in the following databases: PubMed, PEDro, Embase, Cochrane, Scopus, and Web of Science. Randomized clinical trials were included in which participants were aged 18 years or older. Articles were excluded if at least one of the therapies did not involve pulmonary rehabilitation or respiratory muscle training, if the participants were COVID positive, if studies lacked results, and finally, if interventions were conducted without supervision or at home. This review only encompasses supervised non-virtual interventions. This study adheres to the PRISMA statement and has been registered in the PROSPERO database (CRD42023433843).
RESULTS
The outcomes obtained in the included studies are assessed across the following variables: Exercise capacity using the 6-minute walk test, Dyspnea, fatigue, Pulmonary function, Maximum inspiratory pressure, and Quality of life.
CONCLUSION
Despite the absence of a specific treatment at present, it was evident from this review that a well-structured pulmonary rehabilitation program that incorporates both aerobic and muscular strength exercises along with techniques and inspiratory muscle exercises was the most effective form of treatment.

Review
BACKGROUND
The effects of exercise in patients with breast cancer (BC), has shown some profit, but consistency and magnitude of benefit remains unclear. We aimed to conduct a meta-analysis to assess the benefits of varying types of exercises in patients with BC.
METHODS
Literature search was conducted across five electronic databases (MEDLINE, Web of Science, Scopus, Google Scholar and Cochrane) from 1st January 2000 through 19th January 2024. Randomized controlled trials (RCTs) assessing the impact of different types of exercise on outcomes related to fitness and quality of life (QOL) in patients with BC were considered for inclusion. Outcomes of interest included cardiorespiratory fitness (CRF), health-related quality of life (HRQOL), muscle strength, fatigue and physical function. Evaluations were reported as mean differences (MDs) with 95% confidence intervals (CIs) and pooled using random effects model. A p value < 0.05 was considered significant.
RESULTS
Thirty-one relevant articles were included in the final analysis. Exercise intervention did not significantly improved the CRF in patients with BC when compared with control according to treadmill ergometer scale (MD: 4.96; 95%Cl [-2.79, 12.70]; P = 0.21), however exercise significantly improved CRF according to cycle ergometer scales (MD 2.07; 95% Cl [1.03, 3.11]; P = 0.0001). Physical function was significantly improved as well in exercise group reported by 6-MWT scale (MD 80.72; 95% Cl [55.67, 105.77]; P < 0.00001). However, exercise did not significantly improve muscle strength assessed using the hand grip dynamometer (MD 0.55; 95% CI [-1.61, 2.71]; P = 0.62), and fatigue assessed using the MFI-20 (MD -0.09; 95% CI [-5.92, 5.74]; P = 0.98) and Revised Piper scales (MD -0.26; 95% CI [-1.06, 0.55] P = 0.53). Interestingly, exercise was found to improve HRQOL when assessed using the FACT-B scale (MD 8.57; 95% CI [4.53, 12.61]; P < 0.0001) but no significant improvements were noted with the EORTIC QLQ-C30 scale (MD 1.98; 95% CI [-1.43, 5.40]; P = 0.25).
CONCLUSION
Overall exercise significantly improves the HRQOL, CRF and physical function in patients with BC. HRQOL was improved with all exercise types but the effects on CRF vary with cycle versus treadmill ergometer. Exercise failed to improve fatigue-related symptoms and muscle strength. Large RCTs are required to evaluate the effects of exercise in patients with BC in more detail.

Meta-Analysis Review
OBJECTIVE
To investigate the effects of combined exercise on fatigue, anxiety, depression, quality of life and physical functioning in gastroinstestinal neoplasm in people under chemotherapy with oxaliplatin treatment.
METHODS
We searched pubmed/MEDLINE, Cochrane Central Register of Controlled Trials, PEDro data base, and SciELO (until Nov 2023) for randomized controlled trials that investigated the effects of combined exercise in gastroinstestinal neoplasm people under chemotherapy with oxaliplatin treatment. Two comparisons were made: combined exercise versus usual care, combined aerobic and versus usual care (follow up). The main outcomes were muscle strength, aerobic capacity, fatigue, anxiety, depression and quality of life. Mean differences (MD) with 95% confidence interval (CI) were calculated.
RESULTS
Seven randomized controlled trials met the eligibility criteria, which included 464 people. Compared to usual care, combined aerobic and resistance resulted in decrease of general fatigue (-2.82; IC: 4.92 to -0.69, N = 48), physical fatigue (-5.08; IC: 8.41 to -1.74, N = 48) and improvement of domain physical functioning of quality of life (9.40; IC: 2.74 to 16.06, N = 48). Compared to usual care, combined aerobic and resistance - Follow up resulted in decrease of general fatigue (-2.32; IC: 4.41 to - 0.28, N = 48), physical fatigue (-0.92; IC: 3.31 to -1.47, N = 48) and improvement ofdomain physical functioning of (9.83; IC: 0.66 to 19.01, N = 48).
CONCLUSIONS
Our results demonstrate that combined exercises improves fatigue (general; physical), domain physical functioning of quality of life in gastrointestinal neoplasm people under chemotherapy treatment when compared to usual care.

Review
INTRODUCTION
The upper quarter y-balance test (YBT-UQ) is a functional screening tool used to detect musculoskeletal injury risk, aid rehabilitation, and monitor dynamic function, strength and control, yet little is currently known about intrinsic and extrinsic factors that influence reach scores.
OBJECTIVES
This systematic review aimed to determine if age, sex, or interventions influenced reach scores and whether between-limb differences were common in non-injured sporting populations, with a secondary aim to identify if sport impacted YBT-UQ reach.
METHODS
Web of Science, PubMed, and SportDiscus were systematically searched from January 2012 to November 16, 2023, revealing twenty-three studies satisfying inclusion criteria of published in English between 2012 and 2023, healthy participants of any age including both males and females, athletic populations, YBT-UQ use to assess upper limb mobility/stability, report normalised reach scores, and peer-reviewed full-texts. Methodological quality was evaluated via National Institutes of Health (NIH) quality assessment tools for controlled interventions, observational cohort and cross-sectional designs, and pre-post with no control group.
RESULTS
Age, sex, sport, and fatigue were influencing factors; greater reach scores were achieved in older athletes (i.e. >18 years), males, and in a well-rested state. Between-limb differences were not common in sporting populations; therefore, asymmetries may be useful for practitioners to aid injury risk identification.
CONCLUSION
This is the first systematic review investigating YBT-UQ influencing factors and thereby provides context for clinicians regarding characteristics that impact reach scores in sporting populations, from which normative values could be determined and further aid clinical decisions or areas to improve regarding injury risk.
