“…It is now clear that the serum level of CK will increase rapidly and that muscle strength decreases when DOMS occurs because of the damage in the skeletal muscle and the subsequent inflammation after intense exercise (Clarkson and Sayers, 1999;Romagnoli et al, 2015;Muller et al, 2019). The current evidence showed that acupuncture intervention reduced the serum level of CK based on the total effect meta-analysis, as well as the subgroup effect on the time points of 24, 48, and 72 h post exercise-induced DOMS, indicating that acupuncture intervention could improve High quality: Further research is very unlikely to change our confidence in the estimate of effect.…”

Purpose: This systematic review and meta-analysis was designed to evaluate the effects of acupuncture intervention on alleviating delayed onset of muscle soreness (DOMS) after intense exercise. Method: Randomized controlled trials (RCTs) were searched from online databases including Medline (PubMed), Cochrane Library, Web of Science, Embase, PsycINFO, China Knowledge Resource Integrated Database (CNKI), and Wanfang (Chinese) up to April 2019. Data points were extracted from the eligible RCTs at the time points of 24, 48, and 72 h post strenuous exercise-induced DOMS. The outcomes of muscle soreness rating (MSR), creatine kinase (CK), and maximal isometric force (MIF) were pooled into the meta-analysis to assess the acupuncture intervention on DOMS. Results: Six eligible RCTs were included in the meta-analysis, and the results showed that acupuncture intervention significantly decreased MSR [standardized mean difference (SMD) −0.49, 95%CI −0.73 to −0.24, P < 0.001, I 2 = 34%] and the serum level of CK (SMD −0.91, 95%CI −1.27 to −0.56, P < 0.001, I 2 = 30%), accompanied with the improvement of the muscle strength (MIF) (SMD 0.54, 95%CI 0.16 to 0.93, P = 0.006, I 2 = 51%) after intense exercise. At the same time, the findings also revealed that acupuncture intervention had a long-lasting effect and tended to accumulate the effect size and that it had the most efficacy on alleviating DOMS at the time point of 72 h post exercise. Conclusion: The current evidence indicates that acupuncture intervention after intense exercise could be effective for alleviating DOMS and improving muscle recovery. The long-lasting effect of acupuncture intervention on DOMS started from 24 h and would reach a peak on the time point of 72 h post exercise.

Downhill Running: What Are The Effects and How Can We Adapt? A Narrative Review

et al. 2020

Downhill running (DR) is a whole-body exercise model that is used to investigate the physiological consequences of eccentric muscle actions and/or exercise-induced muscle damage (EIMD). In a sporting context, DR sections can be part of running disciplines (off-road and road running) and can accentuate EIMD, leading to a reduction in performance. The purpose of this narrative review is to: (1) better inform on the acute and delayed physiological effects of DR; (2) identify and discuss, using a comprehensive approach, the DR characteristics that affect the physiological responses to DR and their potential interactions; (3) provide the current state of evidence on preventive and in-situ strategies to better adapt to DR. Key findings of this review show that DR may have an impact on exercise performance by altering muscle structure and function due to EIMD. In the majority of studies, EIMD are assessed through isometric maximal voluntary contraction, blood creatine kinase and delayed onset muscle soreness, with DR characteristics (slope, exercise duration, and running speed) acting as the main influencing factors. In previous studies, the median (25th percentile, Q1; 75th percentile, Q3) slope, exercise duration, and running speed were − 12% (− 15%; − 10%), 40 min (30 min; 45 min) and 11.3 km h−1 (9.8 km h−1; 12.9 km h−1), respectively. Regardless of DR characteristics, people the least accustomed to DR generally experienced the most EIMD. There is growing evidence to suggest that preventive strategies that consist of prior exposure to DR are the most effective to better tolerate DR. The effectiveness of in-situ strategies such as lower limb compression garments and specific footwear remains to be confirmed. Our review finally highlights important discrepancies between studies in the assessment of EIMD, DR protocols and populations, which prevent drawing firm conclusions on factors that most influence the response to DR, and adaptive strategies to DR.

How Micro Current Created by Grounding Stimulates Meridian Points in Acupressure?

Acupressure in Oriental medicine is used as a core therapeutic method due to its therapeutic efficacy and minimal side-effects. However, microcurrent stimulation, combined with acupressure and grounding, has not been studied under acupressure conditions in terms of how this combination might affect acupressure therapy's effectiveness. This paper clarifies the new concept of acupressure stimulation combined with a microcurrent that generates electron flow during earthing. In grounding the body, there is free electron movement from and to the body that creates microcurrent. Acupressure uses these currents to activate specific acupoints for therapeutic purposes and activating these acupoints adjust the imbalance between Qi across channels (meridians) and ultimately treat diseases. It is time for proper research and implementation of this technique to increase acupressure efficacy and reduce society's cost.
