Force-Time Characteristics of Repeated Bouts of Depth Jumps and the Effects of Compression Garments.

No studies have reported ground reaction force (GRF) profiles of the repeated depth jump (DJ) protocols commonly used to study exercise-induced muscle damage. Furthermore, while compression garments (CG) may accelerate recovery from exercise-induced muscle damage, any effects on the repeated bout effect are unknown. Therefore, we investigated the GRF profiles of 2 repeated bouts of damage-inducing DJs and the effects of wearing CG for recovery. Nonresistance-trained males randomly received CG (n = 9) or placebo (n = 8) for 72hours recovery, following 20 × 20m sprints and 10 × 10 DJs from 0.6m. Exercise was repeated after 14days. Using a 3-way (set × bout × group) design, changes in GRF were assessed with analysis of variance and statistical parametric mapping. Jump height, reactive strength, peak, and mean propulsive forces declined between sets (P < .001). Vertical stiffness, contact time, force at zero velocity, and propulsive duration increased (P < .05). According to statistical parametric mapping, braking (17%-25% of the movement) and propulsive forces (58%-81%) declined (P < .05). During the repeated bout, peak propulsive force and duration increased (P < .05), while mean propulsive force (P < .05) and GRF from 59% to 73% declined (P < .001). A repeated bout of DJs differed in propulsive GRF, without changes to the eccentric phase, or effects from CG.

The Effect of Compression Garments on Biomechanical and Physiological Factors

To the purpose of this study was to compare muscle oscillation, muscle activation time, and oxygen consumption while wearing compression pants vs. a control garment during running. Methods. Eleven injury-free and recreationally active participants (26.73 ± 12.74 years) were recruited for this study. Participants ran in full-leg compression pants (COMP) and a loose-fitting control garment (CON). Participants ran for 6 min at three submaximal speeds: preferred speed (PS), preferred speed minus 10% (PS − 10%), and preferred speed plus 10% (PS + 10%). The muscle activity of the leg was measured through electromyography (EMG). Muscle oscillation (MO) was measured with accelerometers attached to the thigh and shank. The rate of oxygen consumption (V.O2) and heart rate (HR) were recorded during each condition. MO was assessed over the 0–60 Hz range by averaging power across 10 Hz bins per leg segment. EMG data was processed to identify the activation time. Following each condition, a belief score was recorded. Dependent variables were each compared between conditions using 2 (garment) × 3 (speed) repeated measure ANOVAs (α = 0.05). The relationship between the belief score and dependent variables (compression-control) was analyzed using Pearson’s product-moment correlation (α = 0.05). Results. MO was lower with the full-leg compression pants vs. the control garment (p &lt; 0.05). The muscle activation time for each muscle was shorter while wearing the full-leg compression pants (p &lt; 0.05). Neither the V.O2, RPE, SF, nor the HR were influenced by the garments (p &gt; 0.05). There was no significant correlation between changes in the dependent variables and belief. Conclusion. Wearing compression pants resulted in reduced MO and activation time; however, these changes did not translate into a reduction in V.O2.

Effect of Compression Garments on the Ventilatory Function After Abdominoplasty.

The use of compression garments in the postoperative period of abdominoplasty seems to be a consensus, but the incidents of complications arising from this have been described, related to an increase in intraabdominal pressure and reduction of the femoral vein blood flow that may facilitate thromboembolic events. There are no studies that have evaluated the isolated effect of postoperative compression garments on respiratory function. The purpose of this study was to evaluate the effect of compression garments on respiratory function after abdominoplasty. Thirty-four female patients who underwent standard abdominoplasty were divided into 2 groups, the garment group (n = 18) and the no garment group (n = 16). Respiratory function assessment (with spirometry and manovacuometry) was performed in the preoperative and postoperative periods. Forced vital capacity assessment revealed a greater ventilatory restriction in the garment group. Forced expiratory volume in 1 second (FEV1) showed differences between the evaluation time points in the garment group; the intergroup comparisons showed that the no garment group had a lower FEV1. Slow vital capacity was evaluated with no significant differences found on both intergroup comparisons. The inspiratory capacity was reduced in the garment group, representing ventilatory restriction. Measurements of the maximum inspiratory pressure showed no significant differences between the groups. The maximum expiratory pressure showed significantly lower values on postoperative day 7 in the garment group. The use of compression garments after abdominoplasty impairs ventilatory function. Not wearing this type of garment can improve ventilation, decreasing the risk of pulmonary complications.

Effect of Compression Garments in the Speed Performance among Track and Field and Swimming student-athletes in a Catholic University of the Philippines

Background and Purpose: Speed is critical for sports such as swimming and track and field. One of the sports industry's solutions is compression garments to enhance athletic performance. This study aims to determine the effect of short and long compression garments on the speed performance of track and field and swimming athletes of the University of Santo Tomas.&#x0D; Methodology: The researchers used quantitative and experimental methods. This study focused on the athletes of the track and field and swimming teams of the University of Santo Tomas. The researchers conducted the study at the open field and swimming pool within the vicinity of the University; 14 athletes from track and field and 16 from the swimming team were invited to participate in the 60M Sprint Test and Critical Swim Speed Test.&#x0D; Results: The study shows a slight difference in the speed performance of track and field athletes when using short compression garments (7.54m/s) and long compression garments (7.44m/s). While swimming, the speed performance when using a long compression garment (1.450m/s) is higher than the short compression garment (1.512m/s). Both swimming (0.887) and track and field (0.559) show no significant difference in using the compression garment.&#x0D; Conclusion and Recommendations: Based on the study, there is a minimal difference in using long compression garments against short compression garments. Therefore, the researchers recommend using long compression garments since this garment slightly increases participants' speed which is vital in any sport measuring speed to win a race. The researchers recommend further study by increasing the number of participants, only endurance athletes participants, and including the materials used in making the garments. This further helps the claim that long and short compression garments affect speed performance regardless of sports or events.

In Adult Breast Cancer Patients, the Effect of Compression Garments on Changes in the Volume of Breast Cancer lymphedema: A Literature Review

Background About 21% of women treated for cancer develop breast cancer-associated lymphedema (BCRL), which could lead to negative changes in self-image, increased anxiety and reduced quality of life. Currently, there are a variety of treatments to improve lymphedema, and wearing compression garments is considered necessary, however, evidence is lacking to assess the effectiveness of BCRL compression garments. Purpose To evaluate the efficacy and safety of wearing compression garments for lymphedema volume in adult breast cancer patients. Methods By searching MEDLINE, PubMed, Psych Articles, Academic Search Complete, CINAHL and Cochrane Library, the search was limited to peer-reviewed literature published between 2017 and 2022 in English. Inclusion criteria were participants aged ≥18 years and the intervention was wearing a compression garment. The primary outcome was lymphedema volume change and adverse events. Results A total of 903 literature were obtained, and the literature were screened through the PRISMA flow chart, and five literature that met the criteria were finally included, all of which were randomized controlled trials (RCT). Risk of bias assessment and quality of evidence graded for these five RCTs were performed by two independent researchers using the Cochrane Risk of Bias Tool and the GRADE grading System. The five included RCTs were biased to varying degrees because the intervention was obvious, and the quality of the evidences were moderate, but wearing compression garment was effective and safe in all trials. Conclusion In adult breast cancer patients, wearing compression garments could significantly reduce the volume of lymphedema, and the longer the daily wear time, the better the effect, and the safer than Kinesio Taping. Future studies should conduct higher-quality, multicenter randomized controlled trials to further determine the optimal pressure range for compression garment use.

Muscle perfusion and the effect of compression garments in delayed-onset muscle soreness assessed with arterial spin labeling magnetic resonance imaging.

BackgroundThere is limited information about perfusion in exercise-induced muscle injuries such as delayed-onset muscle soreness (DOMS) and the effect of compression garments as a therapeutic strategy during the regeneration phase. The purpose of this prospective, explorative study was to evaluate muscle perfusion in DOMS and to assess the effect of compression garments at resting conditions and during DOMS by magnetic resonance (MR) arterial spin labeling (ASL).MethodsDOMS was induced from 03/2021 to 04/2021 using an eccentric and plyometric exercises targeting the calf muscles in 14 volunteers. A compression garment (21–22 mmHg) was worn during and for 6 h after exercise on one randomized leg. Magnetic resonance imaging (MRI) including ASL of both lower legs was performed before and directly after the exercise as well as after 6 h, and 48 h using a 3 Tesla MRI system. Perfusion analyses of the gastrocnemius muscle (GM) and the tibialis anterior muscle (TA) were performed and results were compared to baseline measurements. T2-weighted images and creatine kinase levels were acquired at baseline and after 48 h.ResultsAll volunteers presented a successful induction of DOMS in the GM after 48 h. Arterial muscle perfusion in the GM increased from baseline to measurements taken directly after the exercise (4.97±5.59 mL/100 g/min, P<0.001). No significant alteration in perfusion compared to baseline was observed at 6 h (P=0.16) and 48 h (P=1.0) after the induction of DOMS. Compression garments did not elicit a significant alteration in ASL parameters in the GM (P=0.65) or the TA (P=0.05) at any time point. No adverse events occurred during the study.ConclusionsAfter an initial exercise-associated increase in arterial muscle perfusion, a normalization of blood supply was observed at 6 and 48 h after the exercise intervention inducing DOMS. Wearing a compression garment (21–22 mmHg) during and after the induction of DOMS did not affect muscle perfusion at rest, nor did it have any significant effect on muscle perfusion during the regeneration phase. The results can help to better understand the pathophysiological properties of DOMS and may have implications for diagnostic and therapeutic strategies.

Effect of Compression Garment and Low Intensity Exercise on Upper Limb Function and Lymphedema among Post-Mastectomy Women: A quasiexperimental Two Arm Study

Lower limb compression garments do not influence dynamic and static balance performance in young males

Background: Some studies show that wearing compression garments (CGs) improves balance performance. However, the overall evidence supporting their use for balance improvement is inconclusive. Objective: This study aimed to further explore the effect of CGs on balance. Method: Using a cross sectional within subjects repeated measures design fourteen participants (27 ± 3 years) completed three trials for each of four balance tests, under three conditions: compression garment, no garment, and sham. Subjective performance and garment rating scores were also collected following each test condition. A repeated-measures analysis of variance was performed to compare derived variables between conditions for each balance test. Results: No significant differences were found across conditions or tests for either balance performance or subjective measures. Conclusions: This study demonstrated CGs did not influence dynamic or static balance performance in healthy young males. Further, in contrast to other research this study did not demonstrate an effect of compression garments on dynamic or static balance in healthy young males. However, it remains that CGs may provide benefit in other populations including those with balance and movement deficit disorders.

Quantification of the effect of compression garments on fatigue behavior in cycling

Effectiveness of compression garments to enhance athletic performance is the subject of numerous qualitative studies. This study aims at quantification of the effect of compression garments using nonlinear dynamics approach. Kinematic data of fifteen healthy male athletes was obtained and the state space was reconstructed. The trajectory drifts caused by fatigue in the state space were quantified using local flow variation technique. The study illustrates that compression garments (CGs) decrease rate of fatigue development and the body exhibits a more restricted complexity (more predictable and smaller fluctuations) when CGs are worn.

The Effect of Compression Garments on Performance in Elite Winter Biathletes.

To evaluate the effects of wearing upper- and lower-body compression garments on cross-country skiing performance in elite winter biathletes. A total of 7 senior biathletes (4 men and 3 women) from the Swedish national team performed 2 exercise trials in a randomized and counterbalanced order, wearing either commercially available upper- and lower-body compression garments (COMP) or a standard winter-biathlon racing suit (CON). In each trial, the athletes roller-skied on a customized treadmill, completing a time trial simulating the skiing duration of a biathlon sprint race, followed by a time-to-exhaustion test designed to elicit exhaustion within ∼60 to 90 seconds. Heart rate, blood lactate concentration, rating of perceived exertion, thermal sensation, and thermal comfort were monitored throughout each trial, while muscle soreness was measured up to 48hours after each trial. Pressure exerted by the clothing was significantly higher at all anatomical sites for COMP compared with CON (P ≤ .002). Wearing COMP led to small positive effects on time-trial (d = 0.31) and time-to-exhaustion test (d = 0.31) performances compared with CON, but these differences were not statistically significant (P > .05). No significant differences were found for any physiological (heart rate or blood lactate concentration) or subjective (rating of perceived exertion, thermal sensation, thermal comfort, or muscle soreness) responses between COMP and CON (P > .05). Wearing COMP during maximal cross-country skiing may have small but worthwhile beneficial effects on performance for some individuals. Due to individual variation, athletes are advised to test COMP prior to competition.

Wearing compression garments differently affects monopodal postural balance in high-level athletes

This study investigated the acute effects of compression garments (CG) on balance control in elite athletes. 15 male professional handball players were recruited. They had to stand as motionless as possible in a monopedal stance on a force plate with the eyes closed and on a wobble board with the eyes open, while wearing CG or not. Centre of foot pressure mean velocity and surface area were calculated. Statistics were first calculated with the data from the whole sample. A hierarchical cluster analysis was also performed in order to categorize the participants’ behaviours into subgroups with similar characteristics. The whole group analysis showed that there were no significant effects attributed to CG. The clustering analysis identified two distinct and homogeneous subgroups of participants. Only athletes with the best balance abilities at baseline could benefit from CG wearing to improve their balance control. These athletes, who swayed less and were more sensitive to somatosensory manipulation due to CG wearing, seem to control balance by adopting a support-dependent preferred sensorimotor tactic. Our findings suggest that amongst high-level athletes, the ability to benefit from CG wearing to improve balance control seems to depend on participants’ intrinsic balance skills and/or preferred sensorimotor tactics.

635 Compression Garments with Silicone Improve Hypertrophic Scars Compared to Compression Garments Alone: A Retrospective Study

Abstract Introduction The management of hypertrophic scars is one of the major challenges facing healthcare providers in the treatment of burn patients. Two of the mainstay noninvasive clinical practices for hypertrophic scars is the utilization of pressure garments and garments with Silicone gel sheeting. Here, we present a comparison of the effectiveness of compression garments alone and garments with silicone in the treatment of a large pediatric patient population with hypertrophic scars. Methods A retrospective study was performed to compare the effectiveness of compression garments with silicone versus compression garments without silicone in the treatment of pediatric hypertrophic scars. Included in this study were patients who received at least 12 months of follow-up treatment with silicone or non-silicone compression garments between 2013 and 2018. Modified Vancouver Scar Scale (VSS) scores were analyzed 1, 3, 6, 9, and 12 months post-injury/surgery for each scar. Descriptive statistics and t tests were used to summarize and compare the total VSS scores between the two groups. In addition, descriptive and ANOVA statistics were performed to compare the effectiveness of silicone compression treatment for scars located on different regions of the body. Results In total, the compression garment with silicone group included 99 scars of 70 different patients and the non-silicone group included 28 scars of 19 different patients. Before-after total VSS scores for silicone group decreased from 4.11 (SD, 1.522) to 1.47 (SD, 1.268) compared to a decrease from 3.27 (SD, 1.117) to 1.80 (SD, 1.380) for compression group after 12 months of treatment (P&amp;lt; 0.05). ANOVA analysis revealed no statistically significant difference between silicone’s effectiveness on scars located in different regions of the body based on total VSS score after 12 months of treatment (F(4, 99)=1.47, p&amp;lt; 0.05). Conclusions Compression garments with silicone are more effective in treating hypertrophic scars than garments without silicone. The effectiveness of silicone is independent of the scar location assuming sufficient contact and coverage. Applicability of Research to Practice This retrospective study supports the use Silicone compression garments for hypertrophic scars in pediatric patients and is completely applicable to medical practice.

The Effects of Compression Garments on Stability and Lower Limb Kinematics During a Forward Lunge.

Compression garments have been used to minimise injury risk, through improvements in stability and joint positioning; yet, it is unclear whether there is an optimal length or tightness of these garments that may maximise observed benefits. This study measured the effect of three different garment types, at two different tightness levels, on lower extremity stability and alignment during a forward lunge movement. Sixteen healthy adults (7 female, 9 male; 24.3 ± 2.9 years) were recruited as participants. Stability of the lead foot, as well as lower body joint kinematics, were recorded using an Oqus 12-camera system, surrounding participants as they executed three forward lunges onto a Matscan pressure mat under seven compression conditions (Control, Light/Heavy Calf, Light/Heavy Socks, Light/Heavy Leggings). Mean minimum time-to-boundary (mmTtB) (derived from centre of pressure measures) and frontal plane kinematics (lateral pelvic tilt, knee valgus, ankle inversion/eversion) were used to assess the effect of garment tightness and length on lunge stability and joint alignment, respectively. A significant effect of tightness on mmTtB was observed (F(1,105) = 8.192; p = .005, η2 = .072), with Heavy garments eliciting longer mmTtB compared to their corresponding Light (-.18 ± .06 s; p = .015) or Control (-.28 ± .09 s; p = .007) conditions. No significant effects of garment tightness or length on lower body kinematics were evident. The results of this study suggest stability during a forward lunge is improved through the use of tight-fitted compression garments.

Comprehensive pressure profiling to develop next-generation compression treatment for lymphedema: Testing efficacy of high resolution sensors

Evidence for the use and effectiveness of compression garments (sleeves, stockings) for medical conditions including lymphedema and deep vein thrombosis remains empirical. The contemporary mandate for evidence-based medical practices, i.e. the delivery of care based on objective, effective measurements (efficacy), gives impetus for the establishment of both standardized testing protocols and tools enabling accurate spatial and temporal measurements of pressures delivered by compression garments. This study proposes the establishment of Gage Linearity and Bias study protocols to assess efficacy of pressure testing sensors within and between studies. While several such sensors are commercially available, they have not been tested in clinically relevant pressure ranges or contexts. The efficacy of a current commercial, high-resolution and compliance pressure sensor (Tekscan 9833E Medical Sensor) was assessed using Gage Linearity and Bias methods. The Tekscan sensor proved insufficient for the accurate measurement of target pressure ranges applied by lymphedema compression sleeves. The study demonstrates that standardization, and the use of protocol techniques such as the adapted Gage Linearity and Bias methods presented here, lend themselves well for efficacy testing of pressure sensing technologies. Further, this study highlights efforts underway to develop customized sensors and technologies enabling efficacy testing of compression treatments in situ in patients and in age-matched, healthy control subjects. Effective high resolution pressure sensors will enable comprehensive pressure profiling for establishment of efficacy-based compression treatments. Ultimately, effective high resolution pressure sensors will pave the way to elucidate mechanisms underpinning compression treatment and the etiology of lymphedema per se, a poorly understood condition with no current cure.

Effect Of Compression Garments On Cardiovascular Function During Recovery Phase.

The aim of this present research was to determine whether the cardiovascular function has been affected by wearing compression garments during the recovery phase. Fourteen subjects (men, $\text{n}=$7; women, $\textbf{n}=$7; $24.7 \pm 4.5$ years, $166.0 \pm 7.6$ cm; $60.9 \pm 12.0$ kg) completed a running protocol on a treadmill. Each subject participated in two running experiments, using either compression garments (CGs) or non- compression garments (NCGs) during exercise and 2 hours recovering time. Electrocardiogram (ECG) signals were collected during 2 hours recovery using wearable sensors. The present work indicated a statistically significant difference between CGs and NCGs from 90 minutes recovery onwards $( \mathrm {p}<0.05)$. ECG parameters showed some significant difference in heart rate (HR), ST and corrected QT (QTc $) ( \mathrm {p}<0.05)$. Therefore, the cardiovascular function was positively influenced by the application of CGs during the recovery phase.

The Effectiveness Of Compression Garments On EEG During a Running Test.

The specific purpose of this present paper was to investigate whether the EEG activity has been affected by wearing whole body compression garments during a running test. Ten subjects (men, n=5; women, n=5; age: 24.11 ± 4.48 years; height: 163.56 ± 7.70 cm; chest: 87.78 ± 6.92 cm; weight: 58.67 ± 10.96 kg; BMI: 21.77 ± 2.63 kg.m-2) completed a running protocol on a treadmill. Each subject participated in two running trials, wearing either a compression garment (CG) or a non-compression garment (NCG) during exercise. Electroencephalogram (EEG) signals were collected during exercise using wearable sensors. The present study revealed a statistically significant difference between CGs and NCGs in alpha, beta and theta power spectral density (p<0.05). Therefore, the brain activity was influenced by the application of CGs during the running test. This result would also recommends an application of CGs in training as well as in competition.

Effect of Compression Garments on the Development of Delayed-Onset Muscle Soreness: A Multimodal Approach Using Contrast-Enhanced Ultrasound and Acoustic Radiation Force Impulse Elastography.

Delayed-onset muscle soreness (DOMS) is one of the most common reasons for impaired muscle performance in sports. However, little consensus exists regarding which treatments may be most effective, and the underlying mechanisms are poorly understood. To investigate the influence of compression garments on the development of DOMS, focusing on changes in muscle perfusion and muscle stiffness. In this controlled laboratory study with repeated measures, muscle perfusion and stiffness, calf circumference, muscle soreness, passive ankle dorsiflexion, and creatine kinase levels were assessed in participants before (baseline) a DOMS-inducing eccentric calf exercise intervention and 60 hours later (follow-up). After DOMS induction, a sports compression garment (18-21 mmHg) was worn on 1 randomly selected calf until follow-up, while the contralateral calf served as an internal control. Muscle perfusion was assessed using contrast-enhanced ultrasound (peak enhancement and wash-in area under the curve), while muscle stiffness was assessed using acoustic radiation force impulse (shear-wave velocities). A magnetic resonance imaging scan of both lower legs was also performed during the follow-up testing session to characterize the extent of exercise-induced muscle damage. Comparisons were made between limbs and over time. Shear-wave velocity values of the medial gastrocnemius showed a significant interaction between time and treatment (P = .006), with the noncompressed muscle demonstrating lower muscle stiffness values at follow-up compared to baseline or to the compressed muscle. No significant differences in soleus muscle stiffness were noted between limbs or over time, as was the case for muscle perfusion metrics (peak enhancement and wash-in area under the curve) for the medial gastrocnemius and soleus muscles. Further, compression had no significant effect on passive ankle dorsiflexion, muscle soreness, calf circumference, or injury severity, per magnetic resonance imaging. Continuous wearing of compression garments during the inflammation phase of DOMS may play an important role in regulating muscle stiffness; however, compression garments have no significant effects on intramuscular perfusion or other common clinical assessments.

Effect of Compression Garments on Controlled Force Output After Heel-Rise Exercise.

Kato, E, Nakamura, M, and Takahashi, H. Effect of compression garments on controlled force output after heel-rise exercise. J Strength Cond Res 32(4): 1174-1179, 2018-The purpose of this study was to elucidate the effects of compression garments (CG) on controlled force output after strenuous exercise. Sixteen healthy volunteers completed trials both with CG and without CG (control trial: CON) on 2 separate, random days which were at least 1 month apart. Both trials required participants to perform heel-rise exercises from maximal dorsiflexion to maximal plantar flexion 20 times with a single leg. The subjects repeated 3 sets of the exercise and took a rest for 2 minutes between sets. Before and after the heel-rise exercise, mechanical (stiffness) and architectural properties of the gastrocnemius medialis muscle were evaluated using the ultrasound method. Also, isometric maximal voluntary contraction (MVC) of plantar flexion was measured, and the subjects maintained 20% MVC of plantar flexion torque for 20 seconds as steadily as possible (steadiness task) as an index of force control. Repeated 2-way analysis of variance analysis (CG/CON × time) indicated that all the parameters declined immediately after heel-rise exercise in both CG and CON trials. Maximal voluntary contraction did not show different tendencies between CG and CON trials, but muscle stiffness and steadiness declined less in CG than CON (p < 0.05). In conclusion, CG are considered to positively benefit controlled force output after strenuous exercise.
