  • effects of cold water immersion and Compression Garment use after eccentric exercise on recovery
    The Journal of Exercise Nutrition and Biochemistry, 2019
    Co-Authors: Tatsuhiro Maruyama, Sahiro Mizuno, Kazushige Goto
    Abstract:

    PURPOSE The combined effect of different types of post-exercise treatment has not been fully explored. We investigated the effect of combined cold water immersion (CWI) and Compression Garment (CG) use after maximal eccentric exercise on maximal muscle strength, indirect muscle damage markers in the blood, muscle thickness, and muscle soreness score 24 h after exercise. METHODS Ten men performed two trials (CWI + CG and CON) in random order. In the CWI + CG trial, the subjects performed 15 min of CWI (15°C), followed by wearing of a lower-body CG for 24 h after exercise. In the CON trial, there was no post-exercise treatment. The exercise consisted of 6 × 10 maximal isokinetic (60°·s-1) eccentric knee extensions using one lower limb. The maximal voluntary contraction (MVC) and maximal isokinetic (60°·s-1) strength during knee extension, as well as the indirect muscle damage markers, were evaluated before exercise and 24 h after exercise. RESULTS The maximal muscle strength decreased in both trials (p < 0.001), with no difference between them. The exercise-induced elevation in the myoglobin concentration tended to be lower in the CWI + CG trial than in the CON trial (p = 0.060). The difference in the MVC, maximal isokinetic strength, muscle thickness, and muscle soreness score between the trials was not significant. CONCLUSION CWI followed by wearing of a CG after maximal eccentric exercise tended to attenuate the exercise-induced elevation of indirect muscle damage markers in the blood.

    Abstract:

    Objective To investigate the effect of wearing a lower body Compression Garment (CG) exerting different pressure levels during prolonged running on exercise-induced muscle damage and the inflammatory response. Methods Eight male participants completed three exercise trials in a random order. The exercise consisted of 120 min of uphill running at 60% of VO2max. The exercise trials included 1) wearing a lower-body CG with 30 mmHg pressure [HIGH]; 2) wearing a lower-body CG with 15 mmHg pressure [MED]; and 3) wearing a lower-body Garment with < 5 mmHg pressure [CON]. Heart rate (HR), and rate of perceived exertion for respiration and legs were monitored continuously during exercise. Time-course change in jump height was evaluated before and immediately after exercise. Blood samples were collected to determine blood glucose, lactate, serum creatine kinase, myoglobin, free fatty acids, glycerol, cortisol, and plasma interleukin-6 (IL-6) concentrations before exercise, 60 min of the 120 min exercise period, immediately after exercise, and 60 min after exercise. Results Jump height was significantly higher immediately after the exercise in the MED trial compared with that in the HIGH trial (P = 0.04). Mean HR during the 120 min exercise was significantly lower in the MED trial (162 ± 4 bpm) than that in the CON trial (170 ± 4 bpm, P = 0.01). Plasma IL-6 concentrations increased significantly with exercise in all trials, but the area under the curve during exercise was significantly lower in the MED trial (397 ± 58 pg/ml·120 min) compared with that in the CON trial (670 ± 86 pg/ml·120 min, P = 0.04). Conclusion Wearing a lower body CG exerting medium pressure (approximately 15 mmHg) significantly attenuated decrease in jump performance than that with wearing a lower body CG exerting high pressure (approximately 30 mmHg). Furthermore, exercise-induced increases in HR and the inflammatory response were significantly smaller with CG exerted 15mmHg than that with Garment exerted < 5 mmHg.

    Co-Authors: Sahiro Mizuno, Kazushige Goto, Mari Arai, Fumihiko Todoko, Eri Yamada
    Abstract:

    Purpose: To examine the effects of wearing a lower-body Compression Garment with different body coverage areas during prolonged running on exercise performance and muscle damage.Methods: Thirty male subjects were randomly assigned to one of three groups: (1) wearing a Compression tights with 15 mmHg to thigh [n = 10, CT group], (2) wearing a Compression socks with 15 mmHg to calf [n = 10, CS group], and (3) wearing a lower-body Garment with < 5 mmHg to thigh and calf [n = 10, CON group]. The exercise consisted of 120 min of uphill running at 55% of V˙O2max. Heart rate (HR), rate of perceived exertion (RPE), and running economy (evaluated by VO2) were monitored during exercise every 10 min. Changes in maximum voluntary contraction (MVC) of knee extension and plantar flexion, height of counter movement jump (CMJ) and drop jump (DJ), and scores of subjective feelings of muscle soreness and fatigue were evaluated before exercise, and 60 and 180 min after exercise. Blood samples were collected to determine blood glucose, lactate, serum free fatty acid, myoglobin (Mb), high-sensitivity C-reactive protein, and plasma interleukin-6 concentrations before exercise (after 20 min of rest), at 60 min of exercise, immediately after exercise, and 60 and 180 min after exercise.Results: Changes in HR, RPE, and running economy during exercise did not differ significantly among the three groups. MVC of knee extension and plantar flexion, and DJ decreased significantly following exercise, with no difference among groups. The serum Mb concentration increased significantly with exercise in all groups, whereas the area under the curve for Mb concentration during 180 min post-exercise was significantly lower in the CT group (13,833 ± 1,397 pg/mL 180 min) than in the CON group (24,343 ± 3,370 pg/mL 180 min, P = 0.03).Conclusion: Wearing Compression Garment on the thigh significantly attenuated the increase in serum Mb concentration after exercise, suggesting that exercise-induced muscle damage was attenuated

    International Journal of Sports Medicine, 2016
    Co-Authors: Sahiro Mizuno, I Morii, Yoshifumi Tsuchiya, Kazushige Goto
    Abstract:

    The present study examined the effects of wearing a lower-body Compression Garment (CG) after endurance exercise on recovery of physiological function. 18 males were divided into 2 experiments, the downhill running (n=10, DHR) experiments and the level running (n=8, LR) experiments. Subjects performed 30 min of DHR (gradient: − 10%) or LR (gradient: 0%) at 70% of  ˙VO2max with either wearing a CG (CG trial) or normal Garment (CON trial) for 24 h after running. Changes in jump performance (counter movement jump; CMJ, rebound jump; RJ, drop jump; DJ), subjective feelings, circumferences of leg, and blood variables (creatine kinase, myoglobin, interleukin-6, high-sensitivity C-reactive protein) were evaluated before exercise, immediately after exercise, 1, 3 and 24 h following exercise. Running economy was evaluated at 24 h following exercise. CMJ height and RJ index were significantly higher in the CG trial than in the CON trial 24 h after running (P

  • The Effects of Compression Garment Pressure on Recovery from Strenuous Exercise
    International journal of sports physiology and performance, 2017
    Co-Authors: Jessica A. Hill, Glyn Howatson, Ken A. Van Someren, David Gaze, Hayley Legg, Jack Lineham, Charles R. Pedlar
    Abstract:

    Compression Garments are frequently used to facilitate recovery from strenuous exercise. Purpose: To identify the effects of two different grades of Compression Garment on recovery indices following strenuous exercise. Methods: Forty five recreationally active participants (n=26 males and n=19 females) completed an eccentric exercise protocol consisting of 100 drop jumps. Following the exercise protocol participants were matched for body mass and randomly but equally assigned to either a high (HI) Compression pressure group, a low (LOW) Compression pressure group, or a sham ultrasound group (SHAM). Participants in the high (HI) and low (LOW) Compression groups wore the Garments for 72 h post-exercise; participants in the SHAM group received a single treatment of 10 minutes sham ultrasound. Measures of perceived muscle soreness, maximal voluntary contraction (MVC), counter movement jump height (CMJ), creatine kinase (CK), C-reactive protein (CRP) and myoglobin (Mb) were assessed before the exercise protocol and again at 1, 24, 48 and 72 h post exercise. Data were analysed using a repeated measures ANOVA. Results: Recovery of MVC and CMJ was significantly improved with the HI Compression Garment (p < 0.05). A significant time by treatment interaction was also observed for jump height at 24 h post exercise (p < 0.05). No significant differences were observed for parameters of soreness and plasma CK, CRP and Mb. Conclusions: The findings of this study indicate that the pressures exerted by a Compression Garment affect recovery following exercise-induced muscle damage (EIMD), with a higher pressure improving recovery of muscle function.

  • The influence of Compression Garments on recovery after Marathon running
    2014
    Co-Authors: Jessica A. Hill, Glyn Howatson, Ken A. Van Someren, Ian H. Walshe, Charles R. Pedlar
    Abstract:

    Strenuous physical activity can result in exercise-induced muscle damage. The purpose of this study was to investigate the efficacy of a lower limb Compression Garment in accelerating recovery from a marathon run. Twenty four subjects (female, n = 7; male, n = 17) completed a marathon run before being assigned to a treatment group or a sham treatment group. The treatment group wore lower limb Compression tights for 72 hours after the marathon run, the sham treatment group received a single treatment of 15 minutes of sham ultrasound after the marathon run. Perceived muscle soreness, maximal voluntary isometric contraction (MVIC), and serum markers of creatine kinase (CK) and C-reactive protein (C-RP) were assessed before, immediately after, and 24, 48, and 72 hours after the marathon run. Perceived muscle soreness was significantly lower (p 0.05). The use of a lower limb Compression Garment improved subjective perceptions of recovery; however, there was neither a significant improvement in muscular strength nor a significant attenuation in markers of exercise-induced muscle damage and inflammation.

  • user experiences of Garment based dynamic Compression for novel haptic applications
    International Symposium on Wearable Computers, 2019
    Co-Authors: Esther Foo, Simon Ozbek, Walter J Lee, Crystal Compton, Brad Holschuh
    Abstract:

    Compression is a haptic stimulus used in medical interventions (e.g., Compression stockings) and has the potential to be integrated into new research areas (e.g., immersive VR experiences, distributed notification mechanisms), yet remains largely understudied. This work investigates the user experience of Compression Garment technologies that are dynamic, remotely controllable, and low mass, to better address this research gap. Shape memory alloy-based Compression Garments, capable of creating spatially- and temporally- dynamic on-body Compression, were designed and deployed in a user study (n=17, 8M/9F) to understand the effects of Compression, and to draw insights for future Compression-based applications. The major takeaways are: (1) importance of and sizing/fit, (2) individual/gender preferences and need for customizability, and (3) the relationship between context-specific stimulation and perception.

  • iterative design and development of remotely controllable dynamic Compression Garment for novel haptic experiences
    International Symposium on Wearable Computers, 2019
    Co-Authors: Esther Foo, Simon Ozbek, Walter J Lee, Crystal Compton, Brad Holschuh
    Abstract:

    This work encompasses the design and development of Garment-based shape memory alloy (SMA) Compression technology that is dynamic, low-mass, and remotely controllable. Three Garment design iterations are presented, consolidated from past user studies [1], [2], [3]. The designed Garment system has potential to serve as a research tool for understanding parameters necessary to create a desired Compression haptic experience; for broadening the scope of medical/clinical interventions; as well as for enabling new modes of interaction between users separated by distance, especially in areas such as tele-rehabilitation and social mediated touch.

  • Active Compression Garment prevents tilt-induced orthostatic tachycardia in humans.
    Physiological reports, 2019
    Co-Authors: Kevin Kelly, Christopher P. Johnson, Lucy E. Dunne, Brad Holschuh, Michael J. Joyner, Bruce D. Johnson
    Abstract:

    Compression Garments are used by patients with lower extremity edema to help regulate fluid distribution and to prevent orthostatic symptoms. Current Compression stockings are often reported as uncomfortable and adherence is poor. The current study was conducted to assess the efficacy of a novel active Compression Garment on healthy individuals undergoing 60-degree head-up tilts for 10 min to induce venous pooling and subsequent physiological responses. During tilts while Garments were on, participants' absolute change in heart rate relative to baseline was lower (16.7 ± 8.7 BPM) compared to control (20.9 ± 11.47 BPM, P = 0.002). There were no differences in changes in mean arterial blood pressure between conditions (P = 0.303). One participant had a pre-syncopal event which occurred during a tilt without Garments. This participant did not experience pre-syncopal symptoms with the Garments on. All together, these data suggest that a novel active Compression Garment is capable of blunting increases in heart rate during head-up tilt. While untested thus far in patient populations, these Garments may prove efficacious in preventing orthostatic intolerance.

  • Design and Characterization of an Active Compression Garment for the Upper Extremity
    IEEE ASME Transactions on Mechatronics, 2019
    Co-Authors: Carlos Gonçalves, Alexandre Ferreira Da Silva, Ricardo Simoes, João Gomes, Leia Stirling, Brad Holschuh
    Abstract:

    This paper presents the design, development, and testing of an active textile-based wearable Compression device that is capable of delivering a controlled pulsatile Compression. The device uses low spring index nickel titanium (NiTi) coil actuators to produce an applied dynamic pressure of up to 5.5 kPa. The selected NiTi coil actuators produce pressure when thermally stimulated with Joule heating via an applied current (0.3 A), and generate recoverable strains up to 75% in extension. An optical fiber strain sensor was developed to monitor the textile strain and enable the indirect estimation of the applied pressure. A new approach using a passive NiBR spring (in parallel with the NiTi actuators) was also developed to assist the NiTi coils in recovering the detwinned martensite form after cooling. The pressure distribution around a rigid cylindrical shape was also evaluated, showing higher applied pressures (5.5 kPa) where the NiTi coil actuators were located. The strain sensor exhibits high accuracy compared to a reference commercial sensor (as indicated by the high correlation indexes of up to 0.97 between Compression cycle measurements with both solutions).

  • preliminary study of the subjective comfort and emotional effects of on body Compression
    International Symposium on Wearable Computers, 2018
    Co-Authors: Simon Ozbek, Brad Holschuh
    Abstract:

    The sensation of touch is integral to everyday life. Current haptics research focuses mainly on vibrations, tap, and point pressures, but the sensation of distributed pressures such as Compression are often overlooked. We investigated the subjective comfort and emotional effects of applied on-body Compression, specifically on the torso and upper arms, through a pilot user study incorporating a novel, low-profile, and actively-controllable Compression Garment. The active Compression Garment was embedded with contractile shape memory alloys (SMAs) to create dynamic Compression on the body. Qualitative interview data collected (n=8) were used to generate a list of findings to inform the future creation of a computer-mediated Compression Garment that is wearable, comfortable, and safe for use.

  • low intensity resistance training and Compression Garment in the management of breast cancer related lymphedema single blinded randomized controlled trial
    Journal of Cancer Education, 2020
    Co-Authors: Mohammed T. A. Omar, Rehab F. M. Gwada, Ghada S. M. Omar, Rokia M Elsabagh, Abd-el Aziz E. Mersal
    Abstract:

    There is limited evidence regarding the combined effect of exercise and Compression Garment on breast cancer-related lymphedema (BCRL). Therefore, we investigate the effect of low-intensity resistance training alone or in combination with a Compression Garment on lymphedema volume, self-reported lymphedema symptoms, and shoulder mobility and function. A total of 60 women with unilateral BCRL were randomly assigned to low-intensity resistance exercises (Rex group, n = 30) or exercises and Compression Garment (Rex-Com-group, n = 30). Both groups take part in exercises program consisted of 10-12 repetitions at 50 to 60% of one repetition maximum (IRM), three times weekly, for 8 weeks. The primary outcome was lymphedema volume determined by percentage reduction of excess limb volume (ELV). Secondary outcomes were lymphedema symptoms (pain, heaviness, and tightness) and shoulder mobility and function using the disabilities of the arm, shoulder, and hand (DASH) questionnaire. All measurements were standardized and performed before (week 0, W0), after the intervention (week 8, W8), and at follow-up (week 12, W12). A significant reduction in percentage of ELV (p < 0.01), pain severity (p < 0.05), a sensation of heaviness (p < 0.05) and tightness (p < 0.001), and improvement in shoulder range of motion (p < 0.05) and function on DASH scores (p < 0.05) were observed at W8 and W12 in both groups. However, no between-group differences were observed over time. These findings suggest that low-intensity resistance training, irrespective of Garment use, can effectively reduce limb volume and lymphedema symptoms, and increase shoulder mobility and function.
