“…A final consideration for the findings in the present study was the utilization of a clinician-friendly assessment tool using a smartphone and finger sensor, whereas previous studies have utilized traditional ECG-techniques. ( 12 ) This non-invasive and clinician-friendly HRV assessment technique has been previously validated against traditional ECG ( r = 0.99, p < .001) ( 21 , 25 ) and so can be considered acceptable for determining HRV. Therefore, it is unlikely that the equipment bears any substantial influence on the measured outcomes, and more likely the protocol and timing of assessment are responsible for the lack of significant findings.…”

“…The pre-foam–rolling HRV (pre-HRV) measures were obtained using the ithlete™ Finger Sensor™, with the right index finger in a finger sensor connected to an electronic tablet and participants positioned supine. ( 15 , 21 , 25 ) The ithlete™ application collects HRV data in 55 sec and requires participants to follow on-screen prompts to inhale and exhale in rhythm. ( 15 , 18 , 21 , 25 ) Once the participants’ heart rhythm has stabilized, the application indicates it is ready and the clinician may begin the data collection.…”

Background: Self-myofascial release has been demonstrated to increase relaxation and improve blood flow, yet it is unknown if it can elicit an acute effect on heart rate variability (HRV). Purpose: This study aimed to determine if a single-bout of foam rolling could increase parasympathetic activity as measured by HRV. Methods: Twenty (20) participants volunteered and their baseline HRV was assessed using a finger sensor while lying supine, and then a second measure was recorded with them sitting upright with feet on the ground. This study utilized a practical HRV collection method designed for use in the field settings, and the data is recorded in arbitrary units (A.U.). Par-ticipants then oscillated on a closed-cell cylindrical foam roller using their body weight on the triceps surae, hamstrings, quadriceps, lumbar spine, and pectoral muscles each for 60 sec. Participants first massaged the right limb and then repeated on the matching muscle group on the left before continuing to the next region. Follow-up HRV measurements were recorded using the same procedures. Results: Paired samples t tests assessing pre- and post-foam–rolling HRV measures in supine and seated positions revealed no difference between supine measures (p = .05, d = 0.21), nor the seated measures (p = .27, d = 0.17) among all participants. When sexes were analyzed separately, males showed a significant decrease in HRV in supine positions (p = .03, d = 0.33), but females did not (p = .55, d = 0.09). Conclusions: The single bout of foam rolling on large muscle groups did not increase parasympathetic activity as hypothesized. Males and females respond-ed differently in supine positions, but no difference was present in seated positions across sexes. The task of self-massage may have prevented the anticipated response f rom the massage. Further research should investigate if passive massage is more effective on HRV response.

“…With the continuous development of the professionalization of soccer, the training and competition level of soccer is more and more demanding, so the evaluation of the physical function state of soccer players should be based on the training, competition, adjustment, and other different stages of physiological and biochemical indicators of monitoring, to ensure that high-intensity daily training, but also in order to better mobilize a variety of physiological systems during the competition period, including the musculoskeletal, neurological, immune and metabolic services for the sports consumption.

A comprehensive assessment of the physical capabilities and attributes of soccer players is essential for effective college soccer training. The ability to implement targeted tactical training relies on a thorough understanding of each player’s physical condition. This paper presents a monitoring system for soccer players’ bodily functions, developed using inertial sensor technology alongside Beer’s Law, tailored to recognize human body movement states and to measure blood oxygen and heart rate. The system’s efficacy in movement recognition and physiological monitoring was evaluated through comparative testing, assessing its performance against established algorithms. Notably, this system demonstrated a 9.75% improvement in the average accuracy for recognizing walking and running actions compared to the Juha Parkka decision tree algorithm and a 6.5% increase in accuracy over the D.M. Karantonis algorithm for walking action recognition. Heart rate measurements incurred an error of approximately ±2 BPM, with a maximum error of 1.7, and oxygen saturation monitoring displayed an error margin of ±2%, with a maximum deviation of 1.6. These deviations fall within acceptable limits. The results of this study furnish valuable data to support the customization of training content and intensity for college soccer athletes and offer insights for optimizing player selection and tactical strategies during matches.

“…Therefore, it is vital to know what types of physical recreational activities not only allow children to enjoy their free time but also serve to display some other skills necessary for their psychological, affective, and interpersonal growth, developing, among other aspects, the different basic motor skills typical of childhood [ 7 ]. In this paper, gross motor function is understood as changes in terms of body position and its ability to maintain balance, involving posture and mobility [ 8 ], as observed from the research fields of medical sciences, biology, early education, and general physical activity and health [ 9 , 10 , 11 ].…”

Developing gross motor function implies strengthening the basic body position and the balance associated with posture and mobility, for which different teaching models and psycho-pedagogical interventions are applied. Objective: to develop gross motor function in male preschoolers through physical recreational activities based on conductivist (Group 1) and constructivist (Group 2) teaching and determine the best teaching paradigm. Two basic skills were studied in two homogeneous independent samples (walking: w = 0.641; running: w = 0.556), selecting 25 children for each group (3–4 years) through the use of intentional sampling. The gross skills evaluation was based on norms established by the Education Ministry, including a mood assessment. Results: each group improved their basic skills in the post-test (Group 1: W = 0.001; W = 0.001. Group 2: W = 0.046; W = 0.038), but the conductivist paradigm was superior (w = 0.033; w = 0.027). Group 1 presented better indicators in the motor evaluations “Acquired” and “In Process” than Group 2, and lower percentages in the “Initiated” evaluation than Group 2 in the abilities “walking” as well as “running”, which were significantly different in the “Initiated” evaluation (p = 0.0469) for the walking ability, and significantly different in the “Initiated” and “Acquired” evaluations (p = 0.0469; p = 0.0341, respectively) for the running skill. Conclusions: The conductivist teaching model was superior in terms of gross motor function optimization.
