New Training Frontiers in Golf Considerations from a neurosurgical perspective

Background: Golf, a sport gaining popularity globally, poses unique risks to musculoskeletal health, particularly among older players. The repetitive nature of the golf swing and inadequate athletic preparation often lead to injuries, especially in the spine, shoulders, and elbows. This study explores the biomechanics of golf and evaluates innovative training methodologies to mitigate injury risks and enhance performance. Materials and Methodology: The study integrates insights from sports science, neurosurgical assessments, and physical therapy to analyze common injury mechanisms in golf. Data from a comprehensive literature review, including clinical case studies and injury prevalence surveys, were combined with biomechanical evaluations. Modern training approaches such as the Gyrotonic Expansion System, MFT Proprioceptive Tables, and elastic resistance training were examined for their efficacy in improving flexibility, strength, and injury prevention. Results: Findings highlight that injury risk peaks during the downswing and impact phases of the golf swing due to high muscular loads and sudden force application. Older golfers exhibit higher injury rates, attributed to age-related physiological changes such as reduced spinal flexibility and muscle strength. Implementing structured training programs significantly reduced injury incidences and enhanced golfers' biomechanical efficiency. Techniques like Gyrotonic and Body Blade improved spinal mobility and neuromuscular control, while MFT tables optimized balance and coordination. Conclusion: Proper athletic preparation tailored to golfers' needs, incorporating multidisciplinary evaluations and advanced training systems, can mitigate injury risks and prolong active participation in the sport. Integrating these strategies, particularly for older players, enhances both safety and performance, underscoring the need for wider adoption in golf training protocols.

Effects of resistance training on muscle strength in adults with haemophilia: A systematic review and meta-analysis.

Although resistance training is frequently prescribed for people with haemophilia (PWH), no previous meta-analyses have quantified the effect of this intervention on muscle strength, nor the implications of the intervention's modality and duration. (1) To determine the effects of resistance training on muscle strength in adults with haemophilia; (2) To determine the most effective duration and modality among the exercise protocols. A systematic search from inception until 28 November 2023 was conducted in PubMed, Embase, Web of Science, CENTRAL and CINAHL databases. We included randomised controlled trials or before-after studies that involved resistance training without other physiotherapy co-interventions. Study selection, data extraction and risk of bias assessment were independently performed by two reviewers. Disagreements were resolved in consultation with a third author. The level of evidence was determined according to the GRADE methodology. Seven studies were included. Measurements of knee extensor strength and elbow extensor strength were included in the meta-analysis. Subgroup analysis showed significant effects for both elastic resistance protocols (SMD: 0.54; 95% CI: 0.02-1.07) and conventional training (isometric and weight-based equipment) (SMD: 0.88; 95% CI: 0.50-1.25), demonstrating small and moderate effect sizes respectively. Additionally, both protocols of duration 5-7weeks (SMD: 1.16, 95% CI: 0.63-1.69) as well as those of duration ≥8weeks (SMD: 0.57, 95% CI: 0.20-0.94) showed a significant difference. Resistance training is effective in improving muscle strength of the knee and elbow extensors in PWH. Both elastic resistance and conventional training show benefits.

Acute Effects of Combining Weight and Elastic Resistance Exercise on Vascular Function in Older Adults.

Prior research has suggested that resistance exercise may result in a temporary decrease in vascular function, as measured by flow-mediated dilation (FMD), among untrained young individuals. However, the immediate impact of combined elastic and weight resistance training on older adults remains insufficiently explored. We assessed vascular function before, after, and 30 min after acute exercise under three resistance conditions to evaluate whether a combination of weight and elastic resistance exercises has an acute effect on vascular function in older adults. Fourteen older adults (65.6 ± 2.9 years) executed three sets of 12 repetitions at 65% of one repetition maximum (1 RM) of the bench press (BP) exercise. Testing was performed on three separate days as follows: (1) barbell alone (BA); (2) barbell plus elastic bands (10% of 65% 1 RM) (BE10); and (3) barbell plus elastic bands (20% of 65% 1 RM) (BE20). A two-way (time × condition) repeated measures analysis of variance was employed to assess the time and condition effects on flow-mediated dilation (FMD) and pulse wave velocity (PWV). At 0 min post-exercise, FMD was significantly higher during BE10 than during BA (p < 0.05); however, at 30 min post-exercise, no significant difference (p ≥ 0.05) was observed between the three conditions. In each condition, FMD results did not differ significantly at different times (p ≥ 0.05). For FMD, the main effect of the condition (F[2,26] = 3.86, p = 0.034) and that of the time and condition (F[4,52] = 3.66, p = 0.011) were significant. For PWV, only the difference between the BA and BE10 conditions was significant at 0 min (p < 0.05). PWV increased from baseline in the BA condition (p < 0.05) but not significantly in the BE10 and BE20 conditions (p ≥ 0.05). Therefore, BA, BE10, and BE20 demonstrated various changes in vascular function. Long-term training intervention studies are needed to validate these findings.

Rating of Perceived Exertion in the First Repetition is Related to the Total Repetitions Performed in Elastic Bands Training.

Several devices (e.g.,linear transducers) have been used for predicting resistance training intensity. However, subjective scales, such as rating of perceived exertion (RPE), are proposed as reliable and easier-to-use tools for monitoring intensity during resistance training. Accordingly, different perceptive scales have been presented in previous research for monitoring intensity during resistance training with elastic bands. The aim was to assess the accuracy and reliability of RPE for quantifying the potential maximal repetitions that could be performed at a given RPE (from 2 to 8 of 10) obtained in the first repetition. For this purpose, 13 recreationally active participants (age: 26.33 [6.52]years, body mass index: 24.97 [5.08]kg/m2) were involved in two familiarization and two experimental sessions. In each session, participants randomly performed one set at each intensity of the first repetition from 2/10 to 8/10 until volitional failure in three different exercises (fly, military press, and push-press). An individual grip width of the elastic band was chosen in each set. The number of repetitions and heart rate were assessed. Significance level was set at p < .05. Repetitions decreased when intensity increased (p < .01) and heart rate was higher in the global exercise (i.e.,push-press; p < .05), but nonsignificant differences between intensities were reported. The level of experience influenced the number of repetitions performed (p < .05). Intersession reliability was set from good to excellent (range: 0.64-0.91). Therefore, the RPE of the first repetition is a relevant and reliable parameter related to the total number of repetitions performed for each RPE value in trained participants enrolled in elastic bands resistance training.

Post-Activation Performance Enhancement in Pull-Up Exercise with Elastic Resistance Training in Tac-tical Personnel

The Pull-up (PU) is a multi-joint upper body exercise that is included in the physical fitness assessments for tactical occupations such as police, firefighters, and military personnel. This study aimed to evaluate the post-activation performance enhancement (PAPE) in the PU exercise using elastic resistance training (ERT) and traditional resistance training (RT). A total of 18 resistance-trained male firefighters (28.3 [5.6] years; 178.1 [6.8] cm; 78.1 [8.2] kilograms; 24.6 [2.4] kg·m-2) participated in the study and performed four PAPE protocols in a cross-over fashion. Two protocols consisted of three sets of 3 repetitions at 75 and 85% of the maximum repetition (RM) in the lat pull down (LPD-M and LPD-H, respectively). The other two protocols consisted of three sets of 3 repetitions using elastic bands for vertical traction (VTEB) at “moderate” (VTEB- M) and “hard” intensity (VTEB-H), based on the Thera Band perceived exertion scale. Repetitions until failure in the PU exercise were measured before and after the application of the four protocols, with an 8-minute pause before and after the PAPE. Results showed a significant increase on repetitions until exhaustion after all PAPE protocols: LPD-M (P=0.007, d=0.19), LPD-H (P=0.023, d=0.17), VTEB-M (P=0.01, d=0.13) and VTEB-H (P=0.001, d=0.28). The use of ERT and traditional RT at moderate and high intensities represent a proper stimulus for the generation of PAPE in the PU.

Acute Cardiopulmonary Response of High-Intensity Interval Training with Elastic Resistance vs. High-Intensity Interval Training on a Treadmill in Healthy Adults.

This study aims to describe and compare cardiopulmonary and subjective responses during high-intensity interval training with elastic resistance (EL-HIIT) and traditional high-intensity interval training (HIIT) sessions. Twenty-two healthy adults (27.6 ± 4.4 years) performed an EL-HIIT and a HIIT protocol consisting of 10 × 1 min at ~85% V·O2max prescribed by cardiopulmonary-specific tests. Pulmonary parameters, heart rate (HR), blood lactate, and rate of perceived exertion (RPE) were measured during exercise. Paired t-test and Cohen's d effect size were used to compare peak and average values. Two-way repeated measures ANOVA and mixed model with Bonferroni's post hoc test were used to compare each bout during the session. The EL-HIIT session showed higher peak and average values of HR, ventilation (V·E), relative and absolute oxygen uptake (V·O2), carbon dioxide production (V·CO2), and RPE than HIIT (p < 0.05). The effect size (ES) comparing HIIT and EL-HIIT was large for HR, V·E, and lactate (≥0.8) in peak values. Comparing each bout between HIIT and EL-HIIT, no difference was found in peak values (p > 0.05) during the session (excluding baseline, warm-up, and recovery). EL-HIIT presented a more pronounced cardiopulmonary and subjective response than HIIT.

THE EFFECT OF 12-WEEK DIFFERENT TRAINING METHODS APPLIED TO BADMINTON ATHLETES ON SOME BASIC MOTORIC PROPERTIES

This study aimed to examine the effects of 12-week plyometric, elastic resistance and core strength training applied to badminton athletes on some basic motoric properties. For this purpose, 21 badminton players participated equally and randomly in plyometric (PG), elastic resistance elastic (EG) and core strength (CG) training groups. Each training group participated in the experimental training practice as well as badminton training three days a week for 12 weeks. One day before and after the 12-week period, vertical jump, agility, throwing a weighted ball, sit and lie down, hand grip, push-ups, back strength, standing long jump, 10m-50m speed, reaction tests as motoric features; with the clear, drop and smash tests as badminton basic technical skills were measured. The obtained data were analyzed with paired samples t-test for within-group analysis, one-way ANOVA and LSD post-hoc test for between-group analysis. Values were presented as mean, and standard deviation, and were analyzed at a significance level of 0.05. According to the data obtained in the study, there was a significant difference in favor of the posttests in the results of the vertical jump, agility t-test, hand grip strength test, standing long jump test and badminton drop technique test among the pre-post tests in the PG group (p&amp;lt;0.05); in the CG group, there was a significant difference in the results of the push-up test, back strength test, badminton clear technique test and badminton drop technique test in favor of the posttests (p&amp;lt;0.05); in the EG group, there was a significant difference in favor of the posttests in the results of the vertical jump, sit-reach flexibility test, push-up test, badminton clear technique test and badminton drop technique test (p&amp;lt;0.05). Among the groups, between the PG group and the EG and CG groups, in favor of the PG group; it was determined that there was a significant difference in back strength between the CG group and the EG and PG groups in favor of the CG group (p&amp;lt;0.05). As a result, plyometric training has positive effects on lower extremity strength and explosive power properties, core training has positive effects on trunk strength and elastic resistance band training has positive effects on both lower and upper extremity strength and explosive power properties; it can be said that these exercises applied at the same time can positively affect the basic techniques of badminton.&lt;p&gt; &lt;/p&gt;&lt;p&gt;&lt;strong&gt; Article visualizations:&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;img src="/-counters-/edu_01/0205/a.php" alt="Hit counter" /&gt;&lt;/p&gt;

The effect of a 4-week elastic resistance training regimen in horses with non-performance limiting hindlimb lameness

ObjectivesTo evaluate the effect of the Equiband® system on hindlimb kinematics/kinetics, postural stability, and back pain. AnimalsEight horses with mild hindlimb lameness/asymmetry ProceduresHorses were handwalked in the Equiband® system 5 days/week using a graduated exercise plan for 4 weeks. Hindlimb kinematics (inertial sensor system (ISS)), kinetics (stationary force platforms), postural stability (accelerometer), and back pain (mechanical nociceptive thresholds (MNTs)) were evaluated. ResultsNo significant difference in lameness was seen over the course of the study. Significantly improved hindlimb stance duration symmetry at the trot was seen on force plate analysis. There was a significant decrease in craniocaudal and mediolateral range of motion during quiet standing. Significant increase in mediolateral and significant decrease in craniocaudal range of motion were seen at the walk and trot. On baseline MNTs, significantly lower values were found on the lame side versus non-lame side. At 4 weeks, there was only a significant difference in MNTs between lame and non-lame sides at T13. Clinical relevanceThe results of this study suggest that the Equiband® system is effective at improving hindlimb symmetry, spinal stability, and back pain symmetry to hindlimb lameness.

Neuromuscular and acute symptoms responses to progressive elastic resistance exercise in patients with chronic obstructive pulmonary disease: Cross-sectional study.

Quadriceps muscle training is a key part in the rehabilitation of chronic obstructive pulmonary disease (COPD) patients. However, exercise intensity prescription and progression with the typically used elastic bands is challenging. We aimed to evaluate neuromuscular, acute symptoms and cardiorespiratory responses (heart rate and dyspnea) during progressive elastic resistance exercise in patients with COPD. Fourteen patients diagnosed with moderate-very severe COPD performed knee extensions at different elastic resistance levels (i.e., colors). The neuromuscular activity was recorded using surface electromyography for the rectus femoris, vastus lateralis and vastus medialis, together with rate of perceived exertion, perceived quadriceps fatigue, dyspnea, oxygen saturation and heart rate. For the vastus lateralis and rectus femoris, increase of muscle activity was evident from a two-level increment when using the red color. For the vastus medialis, there were no muscle activity progressions. Dyspnea, quadriceps fatigue and especially rate of perceived exertion increased in a dose-response fashion and were correlated with the resistance level and muscle activity at the three muscles. Heavy elastic resistance exercise is feasible in COPD patients without excessive dyspnea and a stable cardiorespiratory response. In general, at least two elastic resistance increments are needed to enhance muscle activity for the vastus lateralis and rectus femoris, while there is no increase for the vastus medialis. These results may help to individualize exercise dosing during elastic resistance training in patients with COPD.

The Efficacy of Upper-Extremity Elastic Resistance Training on Shoulder Strength and Performance: A Systematic Review.

Elastic resistance exercise is a popular mode of strength training that has demonstrated positive effects on whole-body strength and performance. The purpose of this work was to identify the efficacy of elastic resistance training on improving upper limb strength and performance measures for the shoulder. Seven online databases were searched with a focus on longitudinal studies assessing shoulder elastic training strength interventions. In total, 1367 studies were initially screened for relevancy; 24 full-text articles were included for review. Exercise interventions ranged from 4–12 weeks, assessing pre-/post-strength and performance measures inclusive of isometric and isokinetic strength, 1RM strength, force-velocity tests, and throwing-velocity tests. Significant increases in various isometric strength measures (IR:11–13%, ER:11–42%, FL: 14–36%, EXT: 4–17%, ABD: 8–16%), 1RM strength (~24% in bench press), force-velocities, throwing- and serve-velocities (12%) were all observed. Elastic resistance training elicited positive effects for both strength and performance parameters regardless of intervention duration. Similar significant increases were observed in isometric strength and 1RM strength across durations. Isokinetic strength increases were variable and dependent on the joint velocity conditions. Quantifying the dosage of appropriate exercise prescription for optimal strength and performance gains is inconclusive with this study due to the heterogeneity of the intervention protocols.

Elastic resistance training is more effective than vitamin D3 supplementation in reducing oxidative stress and strengthen antioxidant enzymes in healthy men.

ObjectiveToday, reducing oxidative stress and improving the antioxidant system with antioxidant supplements along with exercise training has received a lot of attention. Vitamin D plays a very important role in general health and reducing oxidative stress. The aim of this study was to examine the effect of vitamin D3 supplements during elastic-band resistance training (EBT) on oxidative stress and antioxidant indices in healthy men.MethodsForty healthy men (Serum: 20 ≤ 25 (OH) D ≤ 25 ng/mL) voluntarily participated in the current study and randomly were assigned to EBT-vitamin D3 (ED, n = 10), EBT-placebo (EP, n = 10), vitamin D3 (VD, n = 10), and control (Con, n = 10). EBT was performed three times per week on non-consecutive days for eight weeks, in seven exercises. The subjects in the ED, VD, and EP consumed 50,000 IU vitamin D3 or placebo once every 2 weeks. Ten ccs blood samples were collected before and after exercise training and the total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidase (GPX), and creatine kinase (CK) activities were measured in the plasma. Malondialdehyde (MDA), as the lipid peroxidation index, and 25(OH) D were measured in the plasma.ResultsWe found that there was a significant difference between ED with VD (p = 0.011) and Con (p = 0.022) for MDA. A significant difference was also seen for SOD in ED with VD (p = 0.024) and Con (p = 0.038) and TAC in ED with VD (p = 0.020) and Con (p = 0.030), and GPX in ED with VD (p = 0.040) and Con (p = 0.010). While there were no significant differences between ED and EP in all mentioned variables (p > 0.05).ConclusionFinally, it can be said that elastic resistance training improved antioxidant defence. However, vitamin D3 supplementation during resistance elastic training has no synergistic effect on attenuating oxidative stress indices.

Effects of 4-weeks of elastic variable resistance training on the electrochemical and mechanical components of voluntary electromechanical delay durations.

Literature is conflicted on whether electromechanical delay durations decrease following resistance training programs. Therefore, the aim of this study is to examine the contributions and durations of the electrochemical (EMDE-M) and mechanical (EMDM-F) components to the overall electromechanical delay (EMDE-F) during step isometric muscle actions following 4-weeks of structured, multi-joint, lower-body variable resistance training (VRT) program. Twelve men performed 4-weeks of VRT leg press training utilizing combination of steel plates (80% total load) and elastic bands (20% total load). Training consisted of 3 sets of 10 repetitions at a 10 repetition maximum load, 3dayweek-1 for 4-weeks. EMDE-M, EMDM-F, and EMDE-F was measured at Baseline, Week-2, and Week-4 during voluntary step isometric muscle actions (20, 40, 60, 80, and 100% of maximal voluntary isometric contraction) from the vastus lateralis using electromyographic, mechanomyographic, and force signals. The EMDE-M, EMDM-F, and EMDE-F exhibited decreases in duration following 4-weeks of VRT. In addition, EMDE-M contributed significantly less (42-47%) than EMDM-F (53-58%) to the total duration of EMDE-F across the 4-weeks of VRT. These findings indicated that a structured, VRT program utilizing multi-joint exercise was sufficient to induce decreases in the electrochemical and mechanical processes associated with step isometric muscle contractions. In addition, the utilization of the electromyographic, mechanomyographic, and force signals were capable of quantifying electrochemical and mechanical component changes associated with voluntary muscle contraction. Thus, EMDE-M, EMDM-F, and EMDE-F can be useful in quantifying physiological changes in athletic, clinical, and applied research interventions.

Lipid profile and C-reactive protein changes to elastic-band resistance training in young healthy men

Resistance bands are a device for resistance training routine or rehabilitation program and come in various sizes, lengths, and strengths. The purpose of this study was to investigate the effect of elastic resistance training (ERT) on lipid profiles and C-reactive protein (CRP) changes in young and healthy men. Twenty untrained young and healthy men voluntarily participated in the study and were randomly assigned to the ERT (n=10) and control group (n=10). The ERT group performed three non-consecutive sessions per week for eight weeks. Blood was sampled before training and this was repeated after 72 h of the interval of the last session of ERT. The concentration of CRP and lipid profiles, including changes of high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and total cholesterol (TC), were measured. Also, changes in body fat percentage (BF%) were measured. It was observed that CRP was not significantly affected by ERT (P&gt;0.05). Also, TC and TG did not change significantly due to ERT (P&gt;0.05). However, ERT increased the HDL-C concentration (P=0.001) and significantly decreased LDL-C (P=0.033). It is concluded that although the elastic resistance training failed to improve CRP; however, with a positive impact on some of the lipid profiles and health indices, it can be a useful, simple and low-cost exercise training in health promotion.

Effect of a Comprehensive Loop System on Whole body Exercises Using Elastic Bands

Background:- Strength is the capability of the neuromuscular system to produce force against an externalresistance.1 Muscular performance is regarded as one the significant component in quality of life. Strengthtraining helps to increase the muscular tension which eventually increases the muscular performance.2 Therepeated and consistent resistance training strengthens the muscles.3 Most of the studies shows the effectof elastic resistance training with short term interventions on muscle strength(isotonic elastic resistancetraining) and have shown positive outcomes4. This is the first study investigating on increase in the strengthof concentric, eccentric , as well as isometric muscle contraction and also, as a whole body exerciser withtargeted muscle and group muscle training. In this study we lack the knowledge on how elastic resistancetraining affects the muscle strength in upper and lower body. Therefore, it is important to know if thiscomprehensive loop system, as a special training variable, could improve the strength in adult healthyindividuals. This study will help to determine the effect of comprehensive loop system on whole bodyexerciser using elastic bands, and assess if four weeks of training are sufficient to change upper and lowerlimb strength.Methodology:- Total 30 subjects were included in the study.

Therefore, the tool kit is helpful as a whole body exerciser as well as a specifictargeted muscle exerciser to increase a individual muscle strength and to improve the way of exercisingwithout any hindrance in the aspects of space and heavy machine

COVID-19 and Social Isolation: A Case for Why Home-Based Resistance Training Is Needed to Maintain Musculoskeletal and Psychosocial Health for Older Adults

The coronavirus disease outbreak in China has become the world's leading health headline and is causing major panic and public concerns. Public health guidelines in many countries are suggesting that people stay at home to avoid human-to-human transmission of the virus, which may lead to reduced physical activity and greater feelings of isolation. Such effects may be particularly problematic in older adults due to their reduced physical capacities and their potential for increased mental health issues, such as anxiety and depression. A potential way to minimize many of these side effects of stay-at-home guidelines may be progressive home-based resistance training. A simple way to provide progressive overload in home-based resistance training may involve elastic resistance, which has been demonstrated to provide similar benefits to traditional resistance training equipment typically found in gymnasiums. Recommendations on how older adults can safely and effectively perform elastic resistance training at home are provided.

Elastic Resistance Training Produces Benefits Similar to Conventional Resistance Training in People With Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-Analysis.

The purpose of this study was to investigate the effectiveness of elastic resistance training on improving muscle strength, functional exercise capacity, health-related quality of life (HRQoL), and dyspnea in people with stable chronic obstructive pulmonary disease (COPD). For this systematic review, PubMed, The Cochrane Library, Embase (OVID), PEDro, SciELO, and CINAHL were searched from inception to November 2019. Included studies were randomized clinical trials in which people with stable COPD were allocated to (1) an experimental group that received lower-limb resistance training, upper-limb resistance training, or both using elastic resistance; or (2) a control group that received no or sham resistance training or conventional resistance training using weight machines. Data extraction was performed by 3 review authors. The methodological quality of the studies was assessed using the PEDro scale. Eight studies on 332 participants were included. Knee extensor strength was higher in the experimental group (standardized mean difference=0.52, 95% CI=0.09-0.95) compared with the non-exercise control group. Compared with the conventional exercise control, the experimental group presented similar effects for muscle strength, functional exercise capacity, HRQoL, and dyspnea (95% CIoverlapped the line of no effect for all). Elastic resistance training improves muscle strength in people with COPD. The current review suggests elastic resistance as a potential alternative to conventional resistance training using weight machines, as they show similar effects on muscle strength, functional exercise capacity, HRQoL, and dyspnea. Due to its beneficial effects, including reduced risk of exacerbation-related hospitalizations, exercise training is viewed as the cornerstone of pulmonary rehabilitation in people with COPD. This study shows that elastic resistance training can be an effective, portable, practical, and low-cost alternative to conventional weight resistance training. Training with elastic resistance tubes or bands-which are easy to carry, easy to use, and relatively low cost-can be an effective way to improve strength for people with COPD and promote similar benefits to those achieved with weight machines.

Safety and Effectiveness of Progressive Moderate-to-Vigorous Intensity Elastic Resistance Training on Physical Function and Pain in People With Hemophilia.

Strength training is recommended for people with hemophilia; however, published data are anecdotal and have methodological limitations. The purpose of this study was to evaluate the safety and effectiveness of progressive moderate-to-vigorous intensity elastic resistance training on physical function and pain in this patient population. A randomized controlled trial was conducted in a university laboratory setting where 20 patients (17 with severe, 1 with moderate, and 2 with mild hemophilia) aged 21 to 53years received evaluations at baseline and 8-week follow-up. Participants were allocated to intervention (progressive strength training) or control (usual daily activities) groups. The intervention group trained 2days per week during 8weeks with elastic resistance. Intensity during the first 2weeks was a 20-repetition maximum and increased progressively toward 15, 12, and finally 10 repetition maximum. The primary outcome was muscle strength. Secondary outcomes were the Timed "Up and Go" Test score, sit-to-stand, range of motion, Haemophilia Joint Health Score, kinesiophobia score, global impression of pain change, general self-rated health status, and desire to exercise. The intervention group showed greater strength improvements than the control group in almost all of the joints, with moderate to high effect sizes. The intervention group also showed better Timed "Up and Go" and sit-to-stand scores than the control group (moderate effect size), greater range of motion at the knee flexion with the right leg (trivial effect size), and better Haemophilia Joint Health Score at the left knee (small effect size). The intervention group showed greater overall pain reduction, self-rated overall status, and desire to exercise than the control group. Progressive strength training with elastic resistance performed twice a week during 8weeks is safe and effective in people with hemophilia to improve muscle strength and functional capacity, reduce general pain, and improve self-rated health status and desire to exercise. This study provides evidence for the use of a specific strength training regimen for people with hemophilia. People with hemophilia of differing levels of severity, with adequate coverage with clotting factor, can safely engage in progressive strength training and can improve their functioning.

Elastic resistance training: resistance exercise alternative in the home environment during Covid-19 pandemic

Among the measures adopted by several governments during the COVID-19 pandemic to inhibit agglomeration and consequently the contagion of a high number of people, is the closing of gyms and other spaces for the practice of resisted physical exercise, which can cause detraining both athletes as non-athletes. Thus, the purpose of this communication was to present the possibility of using elastic resistance training in order to minimize the effects of interruptions in training conducted before the isolation period. In this sense, it can be verified that, since performed in a way that respects the principles of resistance training, elastic resistance training is safe and efficient for use regardless of age and gender.
