“…The advances in research using body-worn garments and wearables from recent years have permitted essential findings in different fields. For example, for managing recovery in sports [83][84][85]. However, emerging studies share a focus on healthcare, particularly, regarding the relationship between Heart Rate (HR) and stress, which is the main interest of our study.…”

In recent years, wearable devices have been increasingly used to monitor people’s health. This has helped healthcare professionals provide timely interventions to support their patients. In this study, we investigated how wearables help people manage stress. We conducted a scoping review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) standard to address this question. We searched studies in Scopus, IEEE Explore, and Pubmed databases. We included studies reporting user evaluations of wearable-based strategies, reporting their impact on health or usability outcomes. A total of 6259 studies were identified, of which 40 met the inclusion criteria. Based on our findings, we identified that 21 studies report using commercial wearable devices; the most common are smartwatches and smart bands. Thirty-one studies report significant stress reduction using different interventions and interaction modalities. Finally, we identified that the interventions are designed with the following aims: (1) to self-regulate during stress episodes, (2) to support self-regulation therapies for long-term goals, and (3) to provide stress awareness for prevention, consisting of people’s ability to recall, recognize and understand their stress.

“…These devices are relatively inexpensive and require minimal technological skills from users to analyze and interpret the data ( 10 ). They have been recently used to monitor SmO 2 during different sport scenarios, such as indoor rock climbing ( 11 ), cross-country skiing ( 12 ), and cycling ( 5 ). However, while there are a large number of studies showing the reliability and sensitivity of NIRS ( 13 , 14 ), data showing the reliability and sensitivity of wearable NIRS devices (wNIRS) are lacking ( 15 , 16 ).…”

The present study investigated the reliability and sensitivity of a wearable near-infrared spectroscopy (wNIRS) device in moderate and heavy exercise intensity domains. On three separate days, eleven males performed an incremental test to exhaustion, and in the following visits, four submaximal constant-load bouts (i.e., test and retest) were performed in the moderate-intensity domain (100 and 130 W) and heavy-intensity domain (160 and 190 W). The local tissue oxygen saturation index (SmO 2 ) and pulmonary oxygen uptake (V̇O 2 ) were measured continuously. The absolute SmO 2 and V̇O 2 values and the change (Δ) from the 3rd to 6th min of exercise were calculated. There was good reliability for SmO 2 measurements, as indicated by the high intraclass correlation coefficient analysis (ICC ≥0.84 for all) and low coefficient of variation between the two trials (CV ≤4.1% for all). Steady-state responses were observed for SmO 2 and V̇O 2 from the 3rd to the 6th min in the two moderate-intensity bouts (P>0.05), whereas SmO 2 decreased and V̇O 2 increased from the 3rd to the 6th min in the two heavy-intensity bouts (P<0.05). Together, these findings suggested that the SmO 2 measured with a wNIRS device is reliable and sensitive to track local metabolic changes provoked by slight increments in exercise intensity.

“…NIRS, is a validated (A. Feldmann et al 2019 ; Ryan et al 2013 ) and non-invasive way to ascertain changes in muscle oxygen saturation (SmO 2 ) and haemoglobin (Hb) within the muscle tissue, allowing real-time measurement to determine athletic performance and to monitor oxidative muscle metabolism (Marcon et al 2011 ; Miura et al 2003 ). In sport climbing, there is a rapid muscle desaturation with the onset of isometric hold followed by rapid recovery after the removal of the contraction (Dindorf et al 2023 ) whereas continuous exercise produces a rapid muscle desaturation followed by a prolonged equilibrium at a lower muscle oxygen level (Hesford et al 2013 ). During incremental cycle exercise, SmO 2 has been shown to drop with increasing workload and correlated to lactate and ventilatory thresholds (A. Feldmann et al 2022 ).…”

Purpose The physiological examination of boxing has been limited to systemic response in amateur athletes. The demands of professional boxing have been overlooked, despite the different competition format. We sought to determine the physiological demands placed on skeletal muscle in professional boxing. Methods Ten male professional boxers (age 26 ± 5 years, height 177 ± 4 cm, weight 71 ± 6 kg) were recruited for this observational study. On different days, the athletes completed 6 × 3 min rounds of pad, bag or spar-based training with 1 min recovery between each round. Prior to each session, participants put on a heart rate monitor and near-infrared spectroscopy attached to the belly of the rectus femoris muscle to record heart rate and muscle oxygenation. Results There were significantly less punches thrown in sparring compared to other training modalities (p < 0.001). Skeletal muscle oxygenation across training modalities consisted of a delay, fast desaturation and steady state. Across rounds there was a significant increase in time delay for desaturation (p = 0.016), rate of fast desaturation (p < 0.001) and duration of fast desaturation (p = 0.019). There was a significant difference in sparring for the heart rate where skeletal muscle oxygenation changes occurred compared to pads or bag sessions (p < 0.001). Conclusion The findings highlight differences in the skeletal muscle response to the different training modalities. Practitioners need to be aware of the muscular demands of each session to allow optimal adaptation across a training camp. Training needs to allow the skeletal muscle to achieve a new oxygenation steady state rapidly to promote efficient performance across rounds.
