Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
After 10 minutes of running at a chosen speed, the subject was tested for VO2max (Cosmed K5, Rome, Italy) on a motorized treadmill (Rodby RL2000, Sweden), starting at a comfortable speed and rising one step of 2 km/h every minute until exhaustion. Once VO2max was assessed, the anaerobic threshold (AT) was determined by the Cosmed software using the V-slope method and was later checked and adjusted by two expert observers . Two days after the VO2max test, the subjects visited the laboratory and performed a trial at AT on the treadmill until exhaustion. The trial was stopped by the subject's signalling exhaustion by raising an arm. Blood lactate was measured twice, after the VO2max test and after 3 minutes from the termination of the exhaustion trial using a lactacidometer (Lactate Pro, Germany) to assess the consistency of effort. Body weight and body fat percentage were measured with a Tanita scale-impedenziometer and body height with a Tanita anthropometer. The groups matched for body height, weight, and body fat percentage.
SMT was measured after the exhaustion trial, and after the recovery procedures. After the exhaustion trial, DN and ICE were performed. Ice packs were applied to the quadriceps, hamstrings, and soleus/gastrocnemius muscles for 20 minutes, and DN was performed by inserting the needles at relevant trigger points of the lower limb. PPT was measured before and after the recovery procedures with an FPX50 pressure gauge (Wagner, USA) on the left and right quadriceps, gastrocnemius medialis, and lateralis. The sequence of the measurements after the exhaustion trial followed the same pre-treatment order. A maximal Counter Movement Jump (CMJ) test (best of 3 trials) was recorded with a video analysis app (My Jump Lab, v.4.2.6).
The choice of latent MTrPs (trigger points) was made according to the following criteria \[38\]: 1) palpable taut band; 2) hypersensitive spot on the taut band; and 3) palpation with the reproduction of the patient's symptoms that include different sensory sensations, including pain spreading to a distant area, deep pain, dull ache, tingling, or burning pain. If the above three points are satisfied, it is an active trigger point, and if both 1 and 2 were met, but not 3, then it was considered a latent trigger point. The quadriceps (rectus femoris, vastus medialis, and vastus lateralis), tensor fasciae latae, hip adductors (adductor longus, adductor brevis), hip abductors (gluteus medius, gluteus maximus), and gastrocnemius were examined in each subject following a protocol regarding patient and limb positions reproduced from previous studies . Diagnostic criteria were applied by physical therapists with five years of experience with myofascial pain.
After the skin was locally sterilized, the MTrPs were transcutaneously punctured with a 0.30 mm × 40 mm or 0.30 mm × 75 mm sterilized disposable stainless-steel acupuncture needle. During dry needling, the left thumb or two fingers pressed or held the taut band. The right hand was used to quickly insert the needle into the latent MTrPs, then punctured back and forth into the taut band in different directions until a local twitch response was elicited. Once the first local twitch response was obtained, the needle was moved up and down at approximately 1 Hz until no more local twitch responses were elicited. After pulling out the needle, ischemic compression with a finger was applied for 10-30 seconds. The DN insertion was made by a certified Chinese medicine clinician.
To measure SMT, a Manual Infrared Camera (BX20, HK micro, Hangzhou, China) with a sensor resolution of 1024 × 768 pixels was employed, with a measurement range from 0 °C to 250 °C, a display of 230 × 240 pixels, a thermal sensitivity of 80 mK, and an 8-mm lens. The infrared thermography imaging acquisition was performed with the participant standing up in a relaxed position 1 m from the camera. It was measured in a region of interest (ROI) through five infrared thermography images of different muscle sectors for each muscle on the quadriceps and calf muscles on both legs. We considered the max and min temperature and the central value in the ROI (region of interest). After removing the highest and lowest values, the mean of the three measurements was used for data analysis. The SMT can be affected by environment temperature and humidity due to sweating, evaporation and vasoconstriction/vasodilation response. To maintain consistency, we controlled the air temperature and humidity in the lab. Specifically, the room temperature and humidity were kept at 20.0-23.0 °C and 60-75%, respectively . Sleep (light, deep, REM, and total sleep time, in hours) was measured with a sleep monitor (Huawei Band 8) the night before the exhaustion test and after the recovery procedures . RPE (Scale 20 items) and Lactate (Lactate Pro, Germany) were measured two times, after the VO2max and after the exhaustion test at 3 and 5 minutes, and the highest value was retained. RPE and Lactate were used to assess the consistency of the exhaustion trial. The study was conducted according to the guidelines of the Declaration of Helsinki and approved by the Ethics Committee of Tongji University (approval code: tjdxsr029).
