Does Acupuncture Benefit Delayed-Onset Muscle Soreness After Strenuous Exercise? A Systematic Review and Meta-Analysis

Effects of auriculotherapy on muscle fatigue: A randomized crossover trial

OBJECTIVE

This study aimed investigate the effect of auriculotherapy on exercise-induced muscle fatigue, isometric torque production, and surface electromyographic activity (EMG).

METHODS

Design: Randomized Crossover Trial. The sample consisted of 18 males' volunteers who exercised at least twice a week.

THE SAMPLE WAS RANDOMLY ASSIGNED TO TWO GROUPS

Placebo Group (n = 9) and Treated Group (n = 9), and after seven days, the groups were crossed. The data analysis included 18 participants in each group.

MAIN OUTCOME MEASURE

The muscle fatigue index, force production rate, and EMG of the quadriceps were used for evaluation. The evaluation moments included baseline pre-fatigue, baseline post-fatigue, 48 h post-intervention pre-fatigue, and 48 h post-intervention post-fatigue. Mixed two-way test ANOVA was used to compare times and groups.

RESULTS

The fatigue index for peak torque and work showed no significant effect on time, groups, or interaction (p > 0.05). However, for isometric torque, force production rate, and EMG median frequency and average, the results indicate a positive change in values over time (p < 0.05) (with little practical relevance), with no differences observed between the groups or interaction (p > 0.05).

CONCLUSIONS

In conclusion, auriculotherapy had no effect on exercise-induced muscle fatigue, isometric torque production, and surface electromyographic activity.

Can Acupuncture Improve the Flexibility of Hamstring Muscles? A Randomized, Blinded, and Controlled Pilot Study

(1) Background: The lack of flexibility is frequently reported as a risk factor for hamstring muscle damage. Acupuncture, a therapeutic tool of traditional Chinese medicine (TCM), may play a role in both treatment and prevention by improving muscle strength, microcirculation, and reducing muscle soreness. The primary objective of this pilot study was to examine the immediate effects of acupuncture on hamstring muscle stretching and on the pain or discomfort reported during stretching. (2) Methods: To mitigate heterogeneity effects, and due to the small sample size, the study employed a crossover design in which each participant was tested at three different moments of the experimental period with verum (true acupuncture in selected acupoints), sham (fake acupuncture in zones of the skin not corresponding to any known acupoint but near the selected acupoints), and placebo (stimulation of the selected acupoints with a stainless steel wire and cannula, without puncturing) stimulations. Flexibility and pain or discomfort were assessed using the seat and reach test (SR) and a visual analogic scale (VAS). (3) Results: Significant changes in flexibility were observed after verum acupuncture (p = 0.03), while no significant changes were seen in sham and placebo (p = 0.86 and p = 0.18, respectively). No significant differences were found in pain or discomfort during any of the stimulations (verum, p = 0.55; sham, p = 0.50; placebo, p = 0.58). (4) Conclusions: The results of this pilot study suggest that acupuncture may improve flexibility in the hamstring muscles, though it does not significantly affect pain or discomfort during stretching.

Acupuncture and Dry Needling for Sports Performance and Recovery

ABSTRACT

Acupuncture and dry needling share many similarities in their proposed mechanisms of action and their sports medicine-related applications. Pain is the most common indication for these needling treatments, but there also are some limited studies on their use for ergogenic purposes. Needling can likely improve muscular strength and power, including increasing jump height, and it also can increase flexibility. In terms of sports recovery, acupuncture can not only be used for pain relief after injury, but also can help with routine recovery, such as in delayed onset muscle soreness. There are numerous case reports of acupuncture and dry needling being used to treat athletes for various diagnoses and conditions, however more high quality studies are needed in order to make more specific evidence-based recommendations. Given the high degree of safety and limited adverse events associated with needling treatments, it can likely be promoted in athletes.

HyperCKemia associated with acupuncture: a case report and review of the literature

Background

Acupuncture therapy has been widely used as an alternative therapy to treat multiple diseases, such as sequelae of stroke, pain, facial paralysis and so on. In recent years, few adverse events related to acupuncture treatment have been reported, among which hematoma, bleeding and dizziness are the main manifestations. However, to date, there have been no existing cases reported the association between acupuncture therapy and asymptomatic/pauci-symptomatic hyperCKemia.

Case presentation

We report a patient who developed hyperCKemia during 5 sessions of acupuncture at different frequencies. After stopping acupuncture treatment for 1 month, follow-up showed a significant downward trend in serum creatine kinase (sCK). However, after that this patient started to get acupuncture treatment again in order to improve the sequelae of stroke. Meantime, the sCK rose again.

Conclusion

HyperCKemia may associated with acupuncture therapy. All kinds of adverse events of acupuncture should be recorded comprehensively and objectively so as to improve the safety standard system of acupuncture therapy.

The Prevalence of Use of Various Post-Exercise Recovery Methods after Training among Elite Endurance Athletes

There is now compelling evidence of the effectiveness of a range of post-exercise recovery techniques, including extended nights of sleep, cold water immersion, massage, and compression garments. Currently, limited information is available on post-exercise recovery methods used by elite endurance athletes. Therefore, this study investigated the actual methods of recovery used in this group of athletes. Google Forms were used to collect information on the recovery methods used by elite endurance track and field athletes (n = 153, 61.4% men, 38.6% women; average age: 22.7 ± 4.6 years). The most used methods of recovery were sauna bathing (96.7%), massage (86.9%), daytime nap (81.0%), and long night sleep (at least 9h) (61.4%). Recovery methods with proven effectiveness such as cold water immersion and compression garments were rarely used (15.0% and 7.8%, respectively). Overall, recovery methods were used more often when the tiers of the track and field athletes were higher. Massage and sauna bathing were the most used methods of post-exercise recovery among Russian endurance track and field athletes. In most cases, they were used in conjunction with short daytime nap and long night sleep. Higher tier athletes were more likely to use sauna bathing, massage, long night sleep, and daytime nap but not cold water immersion and compression garments as recovery methods; however, all these methods except for cold water immersion were widely used among elite-tier athletes.
