“…Although no significant difference in BLa-and PI was observed, it was noted that the PI rebounded at 15 min after exercise in the PBC group. In contrast to the previous findings (Hohenauer et al, 2019;Vaile et al, 2011), Vaile tested HR, rectal temperature, blood lactate, resting limb blood flow, and re-exercise ability. Furthermore, the arm blood flow was significantly lower than the active recovery after CWI, whereas the leg blood flow was not different (Vaile et al, 2011).…”

This research aims to describe and compare the effects of partial-body cryotherapy (PBC) and cold-water immersion (CWI) on the physiological responses of soccer players after cycling in a hot and humid environment. Sixteen elite soccer players participated in three experiments, and received CWI (13°C for 15 min), PBC (110°C−140°C for 3 min), and CON (room temperature: 21°C ± 2°C), respectively, after aerobic and anaerobic cycling in a hot and humid environment (temperature: 35°C–38°C; humidity: 60%–70%). Heart rate (HR), blood lactate (BLa-), perfusion index (PI), oxygen saturation (SaO2), core temperature (Tc), skin temperature (Ts), and rating of perceived exertion (RPE) were assessed at baseline and through 20 min (5-min intervals). HR was lower in CWI than CON after 20 min ( p < .05). SaO2 was higher in CWI than PBC and CON between 10 and 20 min ( p < .05). Tc was lower from CWI and PBC than CON between 10 and 20 min ( p < .05). Ts was lower in PBC than CWI between 15 and 20 min ( p < .05). RPE was lower in PBC than CON 20 min after the exercise ( p < .05). No main group differences for BLa- and PI were observed. The physiological effects of PBC are generally similar to CWI. Compared with CON, both CWI and PBC could promote the recovery of physiological indexes within 20 min of exercise in a hot and humid environment. However, PBC can lead to a decrease in SaO2 due to excessive nitrogen inhalation.

“…It has been widely proven that cold treatment reduces body temperature (Costello et al, 2012). More about those indicators after CWI or PBC have consistently been reported (Hohenauer et al, 2019;Vaile et al, 2011).…”

“…Indeed, during the PBC session, ΔO 2 Hb decreased while ΔHHb increased. Cold exposure, regardless of the cryostimulation technique, is well known to induce a decrease in muscle, limbic, and skin blood flow, due to vasoconstriction 61 – 64 . However, this phenomenon is still poorly understood at the brain level.…”

We assessed the effects of a 3-min partial-body cryostimulation (PBC) exposure—where the whole body is exposed to extreme cold, except the head—on cognitive inhibition performance and the possible implications of parasympathetic cardiac control and cerebral oxygenation. In a randomized controlled counterbalanced cross-over design, eighteen healthy young adults (nine males and nine females) completed a cognitive Stroop task before and after one single session of PBC (3-min exposure at − 150 °C cold air) and a control condition (3 min at room temperature, 20 °C). During the cognitive task, heart rate variability (HRV) and cerebral oxygenation of the prefrontal cortex were measured using heart rate monitoring and near-infrared spectroscopy methods. We also recorded the cerebral oxygenation during the PBC session. Stroop performance after PBC exposure was enhanced (562.0 ± 40.2 ms) compared to pre-PBC (602.0 ± 56.4 ms; P < 0.042) in males only, accompanied by an increase (P < 0.05) in HRV indices of parasympathetic tone, in greater proportion in males compared to females. During PBC, cerebral oxygenation decreased in a similar proportion in males and females but the cerebral extraction (deoxyhemoglobin: ΔHHb) remained higher after exposure in males, only. These data demonstrate that a single PBC session enhances the cognitive inhibition performance on a Stroop task in males, partly mediated by a greater parasympathetic cardiac control and greater cerebral oxygenation. The effects of PBC on cognitive function seem different in females, possibly explained by a different sensitivity to cold stimulation.

“…Our study utilized the non-invasive LASCA technique to measure peripheral blood perfusion, which has been widely used to monitor these parameters within muscles as it has a higher spatial and temporal resolution than other non-invasive tools used to dynamically evaluate blood perfusion (Cutolo et al, 2018;Ruaro et al, 2018). A speckle pattern is produced by interference light reflected from different parts of the illuminated surface (Hohenauer et al, 2019). To our knowledge, this study was the first to investigate the effects of SI intervention on FTs blood perfusion using LASCA.…”

The Rolf Method of Structural Integration on Fascial Tissue Stiffness, Elasticity, and Superficial Blood Perfusion in Healthy Individuals: The Prospective, Interventional Study

et al. 2020

View full text Add to dashboard Cite

Introduction: There are multiple theories surrounding the physiological impact of structural integration (SI) with little evidence or research corroborating any of these. The aim of the study was to assess the effectiveness of 10 sessions of SI on fascial tissue (FT) superficial blood perfusion, stiffness, and elasticity in 13 healthy women. Methods: This was a prospective, interventional study. The primary outcome measures were FTs' superficial blood perfusion, stiffness, and elasticity of bilateral selected FT points on the body. Data were collected before and after 10 sessions of SI intervention. Statistical analysis was performed using the non-parametric Wilcoxon test (intragroup comparison). Results: The superficial blood perfusion increased significantly in the most selected FT points on the body (p < 0.05). SI interventions produced significant decreases in selected points (brachioradialis, biceps brachii, and trapezius; p < 0.05) of FT stiffness and significant increases in elasticity (brachioradialis, biceps brachii, triceps surae, and trapezius; p < 0.05), especially in the FT of the right (dominant) upper limb. Conclusion: A 10-session of SI demonstrated positive effects on increasing superficial blood perfusion contributed to a decrease in FT stiffness and an increase in elasticity properties in the dominant upper limb. Data collection for this study is currently underway, and the trial is registered at ISRCTN.com with the identifier: ISRCTN46707309.
