“…The Vrd increases in studies that analysed LD races (García‐Manso et al, 2011; Giovanelli et al, 2016) yet these authors do not contemplate this variable, so we have calculated the Vrd with their data. Similar findings were reported by Rojas‐Valverde et al (2021) after a simulated duathlon. In our study, we have also found increases in Vrd in both muscles after competing in the LD Triathlon World Championship, especially in VL and in males.…”

“…Time‐related parameters (Tc, Td and Ts) have been previously studied in long‐term efforts such as marathons (Gutiérrez‐Vargas et al, 2020), ultra‐marathons (Millet et al, 2002), uphill‐marathons (Giovanelli et al, 2016), ultra‐endurance triathlons (García‐Manso et al, 2011) and duathlons simulation (Rojas‐Valverde et al, 2021). However, there does not seem to be a consensus between these studies.…”

“…Therefore, it seems that the contractile properties response depends on the muscle evaluated. Other authors have also indicated important changes in muscle contractile properties after long‐term efforts such as marathons (Gutiérrez‐Vargas et al, 2020), ultra‐marathons (Millet et al, 2002), uphill‐marathons (Giovanelli et al, 2016), ultra‐endurance triathlons (García‐Manso et al, 2011) and duathlons simulation (Rojas‐Valverde et al, 2021).…”

This study aimed to determine the neuromuscular changes in muscle contractile properties and countermovement jump (CMJ) performance after a long distance (LD) triathlon, inquiring to what extent it is influenced by gender and the evaluated muscle, and to explore for response differences. Four elite (2 females and 2 males) and 18 well-trained triathletes (3 females and 15 males) who competed in the 2019 LD Triathlon World Championship undergone, prior and post-race, a CMJ and a muscle contractile properties assessment in vastus lateralis (VL) and biceps femoris (BF) using tensiomyography. A mixed ANOVA was carried out to detect triathletes' neuromuscular changes after the competition. A large decrease in jump height and flight time was found in CMJ (p = 0.001, η p 2 = 0.767) with gender differences (η p 2 = 0.308). contraction (Tc), delay (Td) and sustain times (Ts) also showed a large decrease (p = 0.001, η p 2 = 0.174-0.413). However, maximum radial muscle belly displacement was not altered by the competition, but did greatly increase radial displacement velocity (p = 0.031; η p 2 = 0.212). No gender differences were found in contractile properties. Correlation analysis between race performance and the jumping and tensiomyography parameters only showed a moderate negative correlation with Tc of the BF in pre-and post-competition (r = −0.44; −0.43; p = 0.05). In conclusion, triathletes after a LD World Championship suffer a sharp drop in jump performance and variations in VL's and BF's contractile properties, showing decreases in Tc, Td and Ts without gender differences. The regular use of these parameters can allow the monitoring of triathlete's neuromuscular fatigue and aid in the distribution of more efficient loads in their training cycles. Highlights. Trainers and researchers in neuromuscular fatigue can have reference data of elite and welltrained triathletes after performing LD race. . The magnitude of change in the CMJ and the contractile properties of BF and VL achieved in competition by these elite reference triathletes can guide to modulate triathletes training. . The regular use of the parameters using these references can allow an exhaustive neuromuscular fatigue monitoring during the sessions or training cycles throughout the season.

“…All protocols for the assessment of neuromuscular and mechanical characteristics using TMG followed the processes previously reported (Gutiérrez-Vargas et al, 2018;Rojas-Valverde et al, 2018;Sánchez-Ureña et al, 2018). TMG parameters reliability has been proven, obtaining excellent inter-rater results by the evaluators for Dm, ICC=0.98; Tc, ICC=0.918; Td, ICC=0.923 (Rojas-Valverde et al, 2020).…”

This study aimed to compare the mechanical and functional muscle performance of three different competitive soccer teams of the Costa Rica professional league (U17, Pro A, and Pro B). Age 20.09 ± 4.32 years old, weight body mass 70.85 ± 7.45 kg, height 174.56 ± 4.97 cm; body fat percentage 13.9 ± 5.06 %; lean body mass 57.90 ± 4.88 kg; lean body mass right lower limb 10.11 ± 0.87 kg; lean body mass left lower limb 10.09 ± 0.92 kg. The variables assessed were muscle time of contraction, muscle radial displacement, delay time, squat jump, and countermovement jump. The devices used were dual ray absorptiometry, tensiomyography, and jump platform. There were differences in weight, body mass, and body fat % (Pro A< U17<Pro B). There was a difference in group squat jump performance (Pro A> U17). There were no significant differences in muscle time of contraction, delay time, or radial deformation. The knowledge of differences in both muscle functional and mechanical performance could lead to new training and recovery methods and protocols considering the player’s professional levels.

“…Examples of the technologies that have emerged as an option to control and monitor different phases of sports programming are tensiomyography [3], inertial measurement devices [4], locomotion tracking systems [5], mobile applications [6], oximeters [7], and heart rate monitors [8]. These technologies provide efficient and effective information for daily monitoring of the effect of changes in physical load prescription, the effectiveness of certain rehabilitation protocols, or the efficiency of recovery and sports physical readaptation processes.…”

Background: Body temperature is often assessed in the core and the skin. Infrared thermography has been used to measure skin temperature (Tsk) in sport research and clinical practice. This study aimed to explore the information reported to date on the use of infrared thermography to detect short-term Tsk responses to endurance exercise and to identify the methodological considerations and knowledge gaps, and propose future directions. Method: A web search (PubMed, Science Direct, Google Scholar, and Web of Science) was conducted following systematic review guidelines, and 45 out of 2921 studies met the inclusion criteria (endurance sports, since 2000, English, full text available). Results: A total of 45 publications were extracted, in which most of the sample were runners (n = 457, 57.9%). Several differences between IRT imaging protocols and ROI selection could lead to potential heterogeneity of interpretations. These particularities in the methodology of the studies extracted are widely discussed in this systematic review. Conclusions: More analyses should be made considering different sports, exercise stimuli and intensities, especially using follow-up designs. Study-derived data could clarify the underlying thermo physiological processes and assess whether Tsk could be used a reliable proxy to describe live thermal regulation in endurance athletes and reduce their risk of exertional heat illness/stroke. Also more in-depth analyses may elucidate the Tsk interactions with other tissues during exercise-related responses, such as inflammation, damage, or pain.
