Abstract
OBJECTIVE The primary objective of this systematic review and meta-analysis was to compare the effects of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) and usual care (UC) on cardiorespiratory fitness (peak V̇O2 ) in cancer patients and survivors. Secondary objectives were to compare the effects of HIIT versus MICT and UC on other cardiopulmonary exercise testing (CPET) indices. Safety and adherence to HIIT were also evaluated. METHODS A systematic review and meta-analysis of controlled trials were undertaken using eligible studies from electronic database searching (inception-December 2019). Mean differences (MD) with 95% confidence intervals (CI) were compared and heterogeneity assessed using Cochran's Q and I2 statistic. RESULTS Twelve eligible studies included 516 participants with post-intervention CPET data. No serious adverse events occurred. Adherence to HIIT ranged between 71.2% and 95.6%. HIIT had significantly higher peak V̇O2 compared with UC (MD = 2.11 ml kg-1 min-1 , 95% CI 0.75-3.47, p = .002). No significant difference was found between HIIT and MICT (MD = 2.03 ml kg-1 min-1 , 95%CI -0.75-4.83, p = .15). HIIT was more effective than UC to improve peak oxygen pulse (MD = 1.59 ml/beat, 95%CI 0.06-3.12, p = .04). CONCLUSIONS Quantitative assessment of HIIT studies indicates good compliance, with a significant effect on peak V̇O2 and peak oxygen pulse compared with UC in cancer patients and survivors. HIIT demonstrates a comparable effect with MICT to improve peak V̇O2 .

Abstract
BACKGROUND Exercise has various positive effects on hemodialysis patients. However, there is no clear evidence which type of exercise yields better results. This study aimed to determine the effects of guided functional training added to the intradialytic cycling on dialysis adequacy and biochemical parameters in hemodialysis patients. Additionally, we aimed to investigate if patients could transfer functional exercise to an unsupervised home environment and retain gained improvements. METHODS Randomization was done to a functional training intervention group (INT) (n = 20) or intradialytic cycling control group (CON) (n = 20). The INT attended a pre-dialysis functional training in the first 8 weeks. In the second 8 weeks, they performed functional exercises at unsupervised home environment on non-dialysis days. During the whole study, both groups participated in the intradialytic cycling program. RESULTS Both groups demonstrated a significant increase in dialysis adequacy (Kt/V) in the eight (0.15, 95% CI 0.06 to 0.24; p = 0.003 for INT and 0.21, 95% CI 0.11 to 0.3; p < 0.001 for CON) and the 16th study week (0.13, 95% CI 0.03 to 0.24; p = 0.017 for INT and 0.13, 95% CI 0.03 to 0.22; p = 0.013 for CON) compared to their baseline values with no significant between-group differences. At week eight, the total cholesterol was significantly lowered in the INT (- 0.34 mmol/L, 95% CI - 0.6 to - 0.07; p = 0.016) and remained lower at week 16 (- 0.32 mmol/L, 95% CI - 0.64 to - 0.01; p = 0.049) with no significant changes in the CON. Low-density lipoprotein levels in the INT were significantly reduced after 8 weeks (- 0.35 mmol/L, 95% CI - 0.64 to - 0.06; p = 0.022) and remained reduced after 16 weeks (- 0.28 mmol/L, 95% CI - 0.52 to - 0.03; p = 0.030). There were no significant differences found for albumin, high-density lipoprotein cholesterol, triglycerides, C-reactive protein, and hemoglobin in both groups. CONCLUSIONS We demonstrated that functional training added to intradialytic cycling improved lipid profile and dialysis adequacy. Additionally, the effects of the unsupervised, home-based program were preserved during the second study phase. This study supports the assumption that combined training is more effective compared to solely intradialytic exercise. TRIAL REGISTRATION ClinicalTrials.Gov, NCT03334123 .

Medicine and science in sports and exercise. 2020;(8):1793-1800
Abstract
PURPOSE We investigated whether obesity adversities such as excessive body fat, compensatory hyperinsulinemia, metabolic endotoxemia, irregular androgenicity, and reduced cardiorespiratory and anaerobic fitness are ameliorated by high-intensity interval training (HIIT) with or without caffeine supplementation in women with obesity. METHODS Twenty-four women with obesity (Asian cutoff point body mass index ≥ 27 kg·m, body fat = 40%) were evenly randomized to caffeine (CAF) and placebo (PLA) trials for an 8-wk HIIT program (10 × 1-min sprints, interspersed by 1-min rest). CAF (3 mg·kg·bw) and PLA were supplemented before each training session. Body fat was assessed by dual-energy x-ray absorptiometry before and after training together with assessments of glucose tolerance (oral glucose tolerance test, or OGTT), lipopolysaccharide endotoxins, testosterone, cardiorespiratory, and anaerobic fitness. RESULTS Significant interaction between HIIT and CAF was found for OGTT glucose and OGTT insulin levels (P = 0.001 and P = 0.049 respectively). HIIT-alone increased glucose at 90 min (P = 0.049) and OGTT insulin at 60 min (P = 0.038). Conversely, HIIT with CAF decreased OGTT glucose at 120 min (P = 0.024) without affecting OGTT insulin. HIIT-alone induced 28.3% higher OGTT insulin (effect size d = 0.59 for area under the curve) and 14.5% higher OGTT glucose (d = 0.28). Conversely, HIIT with CAF decreased OGTT glucose by 19.1% (d = 0.51 for area under the curve) without changing OGTT insulin. HIIT-alone effects on glycemia and insulinemia were concurrent with a 31% increase in lipopolysaccharide endotoxins (P = 0.07; d = 0.78; confidence interval, 5.7-8.7) in the PLA but not in CAF treatment (P = 0.99; d = 0.003; confidence interval, 6.5-10.6), although endotoxin level remained within the recommended healthy thresholds. Furthermore, either HIIT alone or with CAF reduced body fat percentage (P < 0.001, ANOVA main training effects), increased muscle mass (P = 0.002), reduced testosterone (P = 0.005), and increased cardiorespiratory and anaerobic capacity (P < 0.001). CONCLUSIONS HIIT induces fat loss and decreases androgenicity in women with obesity. However, its side effects such as endotoxemia and hyperinsulinemia are ameliorated by caffeine supplementation.

Abstract
BACKGROUND Asymmetric vestibular function, decreased plantar sensation, postural control and functional ability have been associated with fall-related wrist fractures. OBJECTIVE To investigate whether multi-sensory training (MST) improves postural control, vestibular function, foot sensation and functional ability among people with fall-related wrist fractures compared to wrist stabilization training (WT). METHODS This was an assessor-blinded, randomized controlled trial. Ninety-eight participants, age 50-75 years, were randomized to MST or WT. Pre- and post-training measurements: Head Shake Test (HST), Video-Head Impulse Test (vHIT), Semmes-Weinstein Monofilaments (SWF), Biothesiometer (BT), Sensory Organization Test (SOT), 10-m Walk Test (10MWT), Five Times Sit to Stand Test (FTSTS), Activities-Specific Balance Confidence (ABC) and Dizziness Handicap Inventory Scales (DHI). The training period was 12 weeks, with six supervised sessions by a physical therapist and daily home exercises for both groups. RESULTS There were significant endpoint differences in SOT (p = 0.01) between the two groups, in favor of the MST group, but no changes were seen in other outcome variables. Subgroup analysis with participants below normal baseline SOT composite scores indicated that the MST was more effective in improving 10MWT fast (p = 0.04), FTSTS (p = 0.04), SWF (p = 0.04) and SOT scores (p = 0.04) than the WT. CONCLUSIONS MST improves postural control among people with a fall-related wrist fracture. The results further suggest that the program is more effective for those with SOT balance scores below age-related norms.

British journal of sports medicine. 2020;(5):263-271
Abstract
OBJECTIVES To determine, in people with knee osteoarthritis (KOA): i) the effectiveness of adding hip strengthening exercises to quadriceps exercises and ii) the type of hip strengthening exercise with the greatest evidence for improving pain, function and quality of life. DESIGN Systematic review with meta-analysis. DATA SOURCES Medline, Embase, Cochrane, CINAHL and SportDiscus databases were searched from inception to January 2018. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Randomised controlled trials investigating the effect of adding hip exercises to quadriceps exercises in people with KOA on pain, function and/or quality of life were included. Three subgroups of hip exercises were included: resistance, functional neuromuscular or multimodal exercise. RESULTS Eight studies were included. Pooled data provide evidence that combined hip and quadriceps exercise is significantly more effective than quadriceps exercise alone for improving walking function (standardised mean difference -1.06, 95% CI -2.01 to -0.12), but not for outcomes of pain (-0.09, 95% CI -0.96 to 0.79), patient-reported function (-0.74, 95% CI -1.56 to 0.08) or stair function (-0.7, 95% CI -1.67 to 0.26). Subgroup analyses reveal that hip resistance exercises are more effective than functional neuromuscular exercises for improving pain (p<0.0001) and patient-reported function (p<0.0001). Multimodal exercise is no more effective than quadriceps strengthening alone for pain (0.13, 95% CI -0.31 to 0.56), patient-reported function (-0.15, 95% CI -0.58 to 0.29) or stair function (0.13, 95% CI -0.3 to 0.57). CONCLUSION Walking improved after the addition of hip strengthening to quadriceps strengthening in people with KOA. The addition of resistance hip exercises to quadriceps resulted in greater improvements in patient-reported pain and function.

Abstract
Cardiorespiratory fitness is an independent risk factor for cardiovascular disease and shortened life expectancy in breast cancer survivors. This randomised controlled trial (n = 153) was designed for patients with a physically inactive lifestyle prediagnosis and concurrently referred to adjuvant chemotherapy. We compared two 12-week exercise interventions aimed at physiological and patient-reported outcomes (cardiorespiratory fitness, muscle strength, metabolic markers, physical activity, pain, fatigue), including a 39-week follow-up. A supervised hospital-based moderate to high intensity group exercise intervention was compared to an instructed home-based individual pedometer intervention. The two 12-week interventions included oncologists' recommendations and systematic health counselling. Outcomes were measured at baseline and week 6, 12 and 39. Primary outcome cardiorespiratory fitness declined significantly during chemotherapy and was restored in both interventions at follow-up. The interventions effectively engaged breast cancer patients in sustaining physical activities during and following adjuvant treatment. A composite metabolic score improved significantly. Positive cardiorespiratory fitness responders had improved clinical effects on fatigue, pain and dyspnoea versus negative responders. We conclude that a loss of cardiorespiratory fitness among physically inactive breast cancer patients may be restored by early initiated interventions and by adapting to physical activity recommendations, leading to a decreased cardiovascular risk profile in breast cancer survivors.

Kristensen, MB, Isenring, E, Brown, B
Nutrition (Burbank, Los Angeles County, Calif.). 2020;:110548
Abstract
Patients with head and neck cancer experience many problems with eating which make them at high risk of malnutrition. Pre-habilitation swallowing exercises as overseen by a speech pathologist can improve swallowing function. A multidisciplinary approach to care, including effective nutritional screening, assessment and intervention has demonstrated improved outcomes in terms of meet nutritional requirements, improved nutritional status and quality of life. Nutritional recommendations are 1.2-1.5 g protein per kilogram per day and 125kJ/kg body weight per day but as these are guides close monitoring of intake and weight is important. Multidisciplinary teams and telehealth have shown better outcomes for nutrition and swallowing status for head and neck cancer patients and ongoing support is required for best patient care.

Lee, KH, Jung, ES, Choi, YY
Geriatrics & gerontology international. 2020;(7):697-703
Abstract
AIM: The present study investigated the effects of two types of lingual exercise (tongue-hold swallowing and tongue-pressure resistance training) on oral muscle strength, salivary flow rate and subjective oral health of the elderly. METHODS We randomly assigned 74 elderly adults (≥65 years) to three groups (tongue-hold swallowing, tongue-pressure resistance training and control groups). Each group participated in 8 weeks of their appropriately prescribed intervention. We measured anterior tongue strength, posterior tongue strength, lip strength, salivary flow rate and Oral Health Impact Profile-14 score before and after 8 weeks. Differences before and after intervention were observed with a paired sample t-test. Moreover, analyses of covariance and variance were performed to determine the differences in the measured values between the groups. RESULTS The tongue-hold swallowing group showed improvement in both anterior and posterior tongue strength, while the tongue-pressure resistance training group showed a significant increase in only anterior tongue strength. Both the tongue-hold swallowing and tongue-pressure resistance training groups showed increased salivary secretion, with the tongue-pressure resistance training group showing a higher level of salivary secretion. However, the difference in the subjective oral health scores before and after the intervention was not significant. CONCLUSIONS The two lingual exercises strengthened some aspects of tongue muscles and increased the salivary flow rate, with more salivary secretion in the tongue-pressure resistance training group than in the tongue-hold swallowing group. Any evidence of the lingual exercises being able to enhance subjective oral health could not be found. Geriatr Gerontol Int 2020; ••: ••-••.

Abstract
Purpose: To test a novel bladder health tutorial on use of the Knack for overcoming bladder control challenges. The Knack-tutorial is a self-administered vignette-based instructional program on preempting bladder challenges in daily life (urgency, stress-leakage, or urge-leakage) through anticipatory, well-timed pelvic floor muscle contraction at the moment of challenge. Materials and Methods: This is a randomized controlled trial pilot test of 108 women with stress or mixed urinary incontinence. The Knack-tutorial group saw a 15-minute slide show with 10 vignettes portraying use of the Knack in daily life. The slide show format used inserted narrated videos, dubbed and animation enhanced pictures and cartoons, and automatic slide advancement. A control group saw a similarly constructed slide show on incorporating good diet/exercise habits. Outcomes were self-perceived improvement (yes/no, and as 0%-100%) 1 month after viewing the tutorial. Results: We enrolled 123 women, randomizing 64 to Knack-tutorial group and 59 to diet/exercise tutorial group. Eleven and one participant, respectively, did not return. Three did not fill out the self-perceived improvement report. Significant improvement was reported by 71% in the Knack-tutorial group compared to 25% in the diet/exercise group (p < 0.001). Self-perceived improvement was 21%-22% higher (Model I Est: 21.01, SE: 4.25, p < 0.001) in the Knack-tutorial group. Conclusions: An electronic tutorial viewed independent of a health care provider with vignettes showing Knack application to manage the everyday bladder challenges women face shows benefit of a magnitude that warrants more widespread use and rigorous testing. A professional remake of the intervention is now available (www.myconfidentbladder.com).
