The Relationship Between Individually Assessed High-Intensity Accelerations, High-Intensity Decelerations, Sprints, and Technical Performances During Soccer Matches: A Full Season Analysis.

Purpose: This longitudinal study analyzed the relationship between players' physical (sprint distances, number of high-intensity accelerations and decelerations assessed with individual and relative thresholds) and technical (retrieved from SofaScore platform) performances during competition. Methods: Twenty elite players were monitored across a full season. Physical performances were monitored with GNSS devices, retrieving time (s), velocity (km.h-1) and distance (m). Sprint distances were calculated as > 80% of the match peak speed registered across the season. High-intensity accelerations and decelerations were calculated as >75% of the peak values registered across the season. Pearson (r) correlations (with 95% confidence intervals) were calculated to assess the relationship among different physical performance variables and between the physical and technical performance variables. Results: Sprint distances correlated with the number of ball touches (r = -0.36 [-0.49, -0.23], p < .001), accurate passes (r = -0.45 [-0.56, -0.32], p < .001), and dribble attempts (r = 0.30 [0.16, 0.43], p < .001). If players touched the ball more frequently and pass the ball more accurately, they covered shorter sprint distances. However, if players attempted more dribbles, they covered longer sprint distances. Conclusion: Practitioners can develop tactical strategies considering the relationship between sprint distances and technical variables such as ball touches, accurate passes, and dribble attempts.

Randomised controlled trial assessing the effects of 6-week telerehabilitation exercise programme on chronic non-specific neck pain: a study protocol.

Chronic non-specific neck pain is one of the most common musculoskeletal conditions affecting the work and lifestyle of those suffering from it. Physiotherapy interventions, such as strength training and stretching, have positively influenced neck pain. Patient adherence to home-based exercises is a growing concern that could be easily improved through telerehabilitation exercise programmes. This can also be a cost-effective, time-efficient and patient-suitable service. Therefore, this study aims to establish the effectiveness of telerehabilitation exercise intervention by measuring patient adherence, pain score, disability index, cervical range of motion (CROM) and cervical muscle endurance. This randomised controlled trial will include n=60 participants, aged 18-45 years, in a 6-week home-based exercise programme delivered through telerehabilitation or paper-based instructions. Outcome measures from participants will be obtained at baseline and on completion of 6 weeks. These will include the Visual Analogue Scale for Pain, Neck Disability Index questionnaire, CROM by using the CROM instrument and cervical muscle endurance through the Craniocervical Flexion Test. For baseline differences between groups, an independent samples t-test will be used. Repeated measures analysis of variance will be used for within-group and between-group analyses at three different time points (0 weeks, 3 weeks, 6 weeks). Trial registration number:NCT06076174.

Different pitch configurations constrain the external and internal loads of young professional soccer players during transition games.

The aims of this study were to compare the influence of transition game (TG) size on the external and internal loads of young professional soccer players and to describe the high-speed profile of these drills in response to pitch dimensions. Eighteen young professional soccer players (age: 16.1 ± 0.3 years; height: 178.3 ± 5.4 cm; weight: 70.1 ± 6.2 kg) performed a 3vs2 TG on pitches measuring 40 × 30 m (TG30), 40 × 50 m (TG50) and 40 × 70 m (TG70) m. Distance covered (DC); accelerations-decelerations above 1.0 m · s-2 and 2.5 m · s-2; rate of perceived exertion (RPE); maximal heart rate and time above 90%; DC at 18.0 to 21.0 km · h-1 (DC 18-20.9 km · h-1); DC at 21.0 to 23.9 km · h-1 (DC 21-23.9 km · h-1); DC above 24.0 km · h-1 (DC > 24 km · h-1); and peak speed and sprint profile (duration, distance and maximal speed) were measured. TG30 achieved lower DC, DC above 18 km · h-1, peak speed, sprint distance and RPE than TG50 and TG70 (p < 0.01 and p < 0.05) and lower sprint duration and maximal speed sprint than TG70 (p < 0.01). TG30 and TG50 achieved higher Acc > 1.0 and > 2.5 m · s-2 respectively than TG70 (p < 0.05). TG70 showed greater DC above 21 km · h-1, peak speed, sprint distance and maximal speed sprint than TG50 (p < 0.01). Soccer coaches should use larger TGs to overload variables related to high speed and sprint demands during training and smaller TG formats to stimulate the accelerations of the soccer players.

Civil servants' physical activity status and its associated factors in Northeast Ethiopia: applying Health Belief Model.

Background: Identifying the associated factors of the physical activity of civil servants is necessary to increase the practice of physical activity. However, limited studies addressed associated factors of civil servants' physical activity status in Ethiopia. Hence, this study assessed civil servants' physical activity status and associated factors in Northeast Ethiopia. Methods: An institution-based cross-sectional study design was conducted from 28 February to 13 March 2020 and measured physical activity using WHO physical activity definition. Four hundred and eight civil servants were interviewed using a systematic random sampling technique. A descriptive statistics and multivariable logistic regression model were used. Result: The percentage of physical activity for the civil servants of the study was only 2.38, with the prevalence of physical activity status of 64.0% (95% CI 60.4% to 67.61%). Perceived self-efficacy (adjusted OR (AOR)=1.98, 95% CI 1.15 to 4.12), cues to action (AOR=2.12, 95% CI 1.04 to 3.22) and being a health professional (AOR=2.19, 95% CI 1.13, 4.23) were main associated factors of physical activity. However, physical activity was not affected by respondents' sex (AOR=1.01, 95% CI 0.67 to 1.83), educational status (AOR=0.23, 95% CI 0.03 to 1.91), perceived barrier (AOR=0.97, 95% CI 0.91 to 1.04) or perceived benefit (AOR=1.02, 95% CI 0.95 to 1.09). Conclusion: The health profession, self-efficacy and cues to action were the main associated factors of physical activity. Hence, the Sports Bureau and Health Bureau should pay attention to providing information by focusing on improving self-confidence and creating a positive attitude toward physical activity.

Physiological demands in simulated tennis matches and hitting tests take account of the translational and rotational kinetic energy ratio of the ball.

Assessment of fatigue effect on hitting ability in tennis has been controversial in previous studies. The purpose of this study was to determine the relationship between player fatigue and groundstroke type in tennis. We hypothesized that subjects with higher blood lactate concentration during play would apply heavier spin to the ball. We divided players into two groups based on their blood lactate concentration during a pre-measured hitting test (HIGH and LOW). Each group performed a simulated match-play protocol consisting of repeated running and hitting tests, which simulated a three-set match. Heart rate, percent of heart rate reserve, oxygen uptake, pulmonary ventilation, and respiratory exchange were measured. The distance between the ball's landing point and the target, and the ball's kinematics, were recorded during the hitting test between sets. We found no significant difference in ball kinetic energy between groups, but the HIGH group hit the ball with a greater ratio of rotational kinetic energy to total kinetic energy. However, the progression of the simulation protocol did not affect physiological responses (including blood lactate concentration) or hitting ability. Therefore, it is suggested that the type of groundstrokes used by players is one of the factors that should be considered when discussing fatigue in tennis.

Physiological demands and physical performance determinants of a new firefighting simulation test.

The study aimed to examine physiological responses of firefighters performing a firefighting simulation test (FST) and to determine the relationship between physical fitness parameters and FST performance. Aerobic fitness, muscular strength, muscular endurance, and anaerobic capabilities were evaluated in 37 firefighters (21-profesionals and 16-volunteers firefighters). Furthermore, participants carried out the FST during which we measured performance, respiratory gas exchange, heart rate (HR), perceived exertion and blood lactate concentrations. Males were significantly faster than females for all tasks of the FST (p < 0.01); however, final performance score (16.5 ± 2.9 and 14.5 ± 2.6 points for males and females, respectively), HR (94.0 ± 2.0% and 93.7 ± 2.3% of HRmax) and perceived exertion (8.1 ± 0.9 and 7.1 ± 1.3) were not significantly different. Prediction of FST performance by LASSO regression revealed a model that included mainly aerobic capacity and maximal strength. In conclusion, FST challenged both aerobic and anaerobic energy metabolisms for both males and females and requires various physiological abilities to perform. Practitioner Summary: For the safety of firefighters and victims, firefighters must meet minimum physical requirements. 37 firefighters performed physical tests and a new firefighting test implemented for the recruitment of firefighters in France. The results revealed that this test is strenuous and that performance is associated with cardiorespiratory fitness and muscular strength. Abbreviations: V̇O2: oxygen consumption; V̇CO2: carbon dioxyde production; V̇E: expired ventilation; RER: respiratory exchange ratio; FST: firefighting simulation test; MAS: maximal aerobic speed; HR: heart rate; RPE: rating of perceived exertion; MVC: maximum voluntary contraction; IMTP: isometric mid-thigh pull; TTE: time to exhaustion; Ppeak: peak power; Pmean: mean power; LASSO: least absolute shrinkage and selection operator; La-: blood lactate concentration.

Methods to assess validity of positioning systems in team sports: can we do better?

Objectives: There is previously reported a large variety of criterion measures and reference systems applied to validate position tracking systems in sports. This study aims to investigate the effect of different criterion measures and reference systems on the outcome of accuracy assessments of tracking systems in sports. Methods: Data from a commercially available standalone global navigation satellite system (GNSS) were compared with two different reference systems: a high-end differential GNSS and a tape measure. Differences in accuracy outcomes of position (static and dynamic), distance and speed (mean and instantaneous) were investigated in team sport imitation courses. Results: The mean horizontal position error was larger when athletes were in motion (dynamic position; 1.53±0.82 m) compared with static measurements (1.10±0.60 m). Measured distances of the courses were markedly different (+6% to -17%) between the two reference systems, causing differences in error. Differences in error were also found between mean speed and instantaneous speed (0.10 vs 0.28 m). Errors in mean speed were highly affected by the time over which speed was averaged. Conclusion: Choice of criterion measure and reference system has a substantial impact on the accuracy assessments of tracking systems. Specifically, assessing static position is not a substitute for dynamic position, and mean speed is not a substitute for instantaneous speed. Therefore, the outcomes of validation studies should always be interpreted in light of the reference methods that were used.

Individual and situational factors affecting the movement characteristics and internal responses to Touch match-play during an international tournament.

PURPOSE: To examine the influence of individual and situational factors on the movement characteristics and internal responses of players to an international Touch tournament. METHODS: Using 47 International Touch players (25 men and 22 women), the associations between the movement characteristics and internal responses with individual (sprint, glycolytic test, Yo-Yo intermittent recovery test level 1 [Yo-Yo IR1], jump performance and well-being) and situational (sex, squad, position, competition day, points scored/conceded, result, and opposition rank) factors were examined using linear mixed modelling. RESULTS: Yo-Yo IR1 distance was associated with all movement characteristics and internal responses (r = -0.29 to 0.37), whilst sprint and glycolytic times only influenced mean heart rate (HRmean) (r = 0.15) and high-speed distance (r = 0.10), respectively. Sex influenced high-speed distance (r = -0.41), whilst squad was associated with playing time and HRmean (r = -0.10-0.33). Other associations included: playing position with all movement characteristics (r = -0.67-0.81); points conceded with relative distance (r = -0.14); winning with high metabolic power and session RPE (r = -0.07-0.09), and opposition rank with HRmean and RPE (r = 0.11-0.35). CONCLUSIONS: Individual and situational factors can influence the movement characteristics and internal responses to Touch and should be considered when developing the characteristics of players and interpreting responses to match-play.

The effects of different small-sided games configurations on heart rate, rating of perceived exertion, and running demands in professional soccer players.

We examined the effects of different small-sided games (SSG) configurations on heart rate (HR), rating of perceived exertion (RPE), and running demands in soccer players. Twelve male soccer players (U18) participated in this randomized cross-over study. Players performed three SSG in different "fixed" and "dynamic" pitch sizes (3v3 in large (SSGL) and small (SSGS) fixed area; or 3v3 in dynamic dimensions [SSGD]), with 4x4 minutes interspersed by 2 minutes of rest. HR measures (maximum [HRmax], average [HRavg], and percentage of maximum [%HRmax]), RPE, and running demands were collected across the SGG sessions. The following running activities were recorded: total distance covered (TD), distance covered (DC) at 6-12 km·h-1, ≥ 12-18 km·h-1, and >18 km·h-1, peak running speed, acceleration (ACC) and deceleration (DEC) at 1-2 m·s-2 and 2-3 m·s-2, player load, and high metabolic load distance (HMLD). SSGL displayed higher HRavg, %HRmax, and RPE values than SSGS (p < 0.05). SSGL resulted in higher TD, DC at 6-12 km·h-1, ≥ 12-18 km·h-1, > 18 km·h-1, and higher peak speed than SSGS and SSGD (p < 0.05). Moreover, SSGD presented higher TD and DC at 6-12 km·h-1 and ≥ 12-18 km·h-1 than SSGS (p < 0.05). In contrast, SSGD and SSGS showed higher number of ACC and DEC at 1-2 m·s-2 than SSGL (p < 0.05). In conclusion, the pitch size and playing area of the SSG can be manipulated to promote desired physiological and physical demands in young soccer players.HighlightsWe examined how fixed (small and large) or variable (dynamic) pitch sizes affected the psychophysiological and running demands of young soccer players during small-sided games.Small-sided games with larger pitch sizes and areas per player elicited greater psychophysiological and running demands than small areas.The pitch size designed in the current study does not appear to affect the number of acceleration and deceleration (> 2 m·s-2).Varying the pitch size during the small-sided games (i.e. dynamic condition) could be an interesting constraint to be considered by soccer coaches in order to enhance task variability.

Physiological Effects of Training in Elite German Winter Sport Athletes: Sport Specific Remodeling Determined Using Echocardiographic Data and CPET Performance Parameters.

Nine ski mountaineering (Ski-Mo), ten Nordic-cross country (NCC), and twelve world elite biathlon (Bia) athletes were evaluated for cardiopulmonary exercise test (CPET) performance and pronounced echocardiographic physiological cardiac remodeling as a primary aim of our descriptive preliminary report. In this context, a multicenter retrospective analysis of two-dimensional echocardiographic data including speckle tracking of the left ventricle (LV-GLS) and CPET performance analysis was performed in 31 elite world winter sports athletes, which were obtained during the annual sports medicine examination between 2020 and 2021. The matched data of the elite winter sports athletes (14 women, 17 male athletes, age: 18-32 years) were compared for different CPET and echocardiographic parameters, anthropometric data, and sport-specific training schedules. Significant differences could be revealed for left atrial (LA) remodeling by LA volume index (LAVI, p = 0.0052), LV-GLS (p = 0.0003), and LV mass index (LV Mass index, p = 0.0078) between the participating disciplines. All participating athletes showed excellent performance data in the CPET analyses, whereby significant differences were revealed for highest maximum respiratory minute volume (VE maximum) and the maximum oxygen pulse level across the participating athletes. This study on sport specific physiological demands in elite winter sport athletes provides new evidence that significant differences in CPET and cardiac remodeling of the left heart can be identified based on the individual athlete's training schedule, frequency, and physique.

The Physical Activity-Dependent Hematological and Biochemical Changes in School Horses in Comparison to Blood Profiles in Endurance and Race Horses.

Blood testing is one of the most important ways to improve performance, facilitate recovery and monitor the training of endurance and race horses. However, little is known about the physical activity-dependent changes of blood parameters in horses used for pleasure and in riding schools. This study aimed to perform routine blood tests for training monitoring of sport horses in three different horse types of use. Then the values of blood indicators were compared between school, endurance and race horses to find similarities in the physical activity-dependent profile. The study was carried out on 15 endurance, 15 race and 15 school healthy horses who underwent the typical effort for their disciplines. The hemogram parameters, creatine phosphokinase (CPK), aspartate aminotransferase (AST), blood lactate (LAC), and total serum protein (TSP) concentrations were measured using the same protocol and equipment. Measurements of main hematological and biochemical physical activity-dependent parameters were conducted before, immediately after and 30 min after training. In school horses, the physical activity-dependent increase of WBC (40.9%) and CPK (76.4%) was similar to endurance horses, whereas an increase of RBC (19.1%), HGB (18.6%) and HCT (19.4%) were more similar to race horses. The moderate effort-dependent increase of LAC concentration (2775%) was lower than in race horses (7526%) and higher than in endurance horses (390%). Limiting the training or work monitoring assessment of school horses to only the endurance or racing blood profile may result in the omission of significant changes in hematological and biochemical parameters.

Comparison of Physiological and Perceptional Responses to 5-m Forward, Forward-Backward, and Lateral Shuttle Running.

PURPOSE: The aim of this study was to investigate the physiological and perceptional responses to forward, forward-backward, and lateral shuttle running. METHODS: Twenty-four eligible male subjects performed a maximal oxygen uptake (VO2max) test and three directional modes (i.e., forward, forward-backward, and lateral) of 5-m shuttle running at the speed of 6 km⋅h-1 for 5 min on separate days. Heart rate (HR) and oxygen uptake (VO2) were continuously measured during the whole tests. Rating of perceived exertion (RPE) was inquired and recorded immediately after the test. Capillary blood samples were collected from the earlobe during the recovery to determine the peak value of blood lactate concentration ([La-]peak). RESULTS: Running directional mode had significant effects on HR (F = 72.761, P < 0.001, η2 p = 0.760), %HRmax (F = 75.896, P < 0.001, η2 p = 0.767), VO2 (F = 110.320, P < 0.001, η2 p = 0.827), %VO2max (F = 108.883, P < 0.001, η2 p = 0.826), [La-]peak (F = 55.529, P < 0.001, η2 p = 0.707), and RPE (F = 26.268, P < 0.001, η2 p = 0.533). All variables were significantly different between conditions (P ≤ 0.026), with the variables highest in lateral shuttle running and lowest in forward shuttle running. The effect sizes indicated large magnitude in the differences of all variables between conditions (ES = 0.86-2.83, large) except the difference of RPE between forward and forward-backward shuttle running (ES = 0.62, moderate). CONCLUSION: These findings suggest that the physiological and perceptional responses in shuttle running at the same speed depend on the directional mode, with the responses highest in lateral shuttle running, and lowest in forward shuttle running.

Investigating the effect of bouncing type on the physiological demands of trampolining.

Purpose: The aim of this study was to investigate whether altering the bounce style affects the physiological demands of trampolining. Methods: Twenty-eight healthy adults completed five, three-minute exercise bouts on a trampoline where; heart rate (HR), V ˙ O 2 (mL/min) and rate of EE (kJ/min) were collected for five different bouncing variations. Results: A one-way repeated measures MANOVA was then used to assess whether significant differences existed between the different bounce types for HR V ˙ O 2 and EE. A significant difference was found ( F 12 , 280 = 20.886, p = 0.0005), so a series of one-way repeated measures ANOVAs were used to identify the degree of significance. For V ˙ O 2 ( F 2.421 , 27 = 64.079, p = 0.0005, ηp 2 = 0.7) and EE ( F 2.989 , 27 = 44.979, p = 0.0005, ηp 2 = 0.6). Post-hoc tests found that for both V ˙ O 2 and EE a significant difference existed between the conventional bounce and each of the bounce variates (p = 0.0005). Conclusion: The results from this study indicated altering the bounce style does have a significant effect on the physiological demands of trampolining. The energy expenditure (EE) equation for trampolining can now be updated to more accurately reflect the rate of EE while performing different bounce styles.

A Conceptual Model of the Healthy Acoustic Environment: Elements, Framework, and Definition.

Noise has been proved to be a risk factor of physiological and psychological health. Therefore, creating a high-quality acoustic environment for people is particularly important. The aims of this study are to explore the basic elements, propose a conceptual framework, and identify the definition of a healthy acoustic environment. Through the method of grounded theory, 75 respondents participated in interviews. The results revealed that (1) "sound sources and acoustic environment," "people's demands," "criteria and standards of a healthy acoustic environment," "matching process," "secondary fitting process," "context," and "acoustic environment quality" are the basic elements of a healthy acoustic environment; (2) "matching process" and "secondary fitting process" connect all the other categories and reflect the processes by which a healthy acoustic environment is judged; (3) based on the associations revealed in the framework, a healthy acoustic environment is defined as a supportive acoustic environment that can match people's physiological, psychological, and behavioral demands in context, and that also fits the criteria and standards. The proposal of a conceptual model for a healthy acoustic environment can provide a new perspective on designing and establishing a high-quality acoustic environment required by people in the near future.

Validation methods for global and local positioning-based athlete monitoring systems in team sports: a scoping review.

BACKGROUND/OBJECTIVE: Global navigation satellite systems (GNSS) and local positioning systems (LPS) are to date common tools to measure external training load in athletes. The aim of this scoping review was to map out and critically appraise the methods used to validate different GNSS and LPS used in team sports. METHOD: A total of 48 studies met the eligibility criteria and were included in the review. The reference systems applied in the validations, and the parameters investigated were extracted from the studies. RESULTS: The results show a substantial range of reference systems used to validate GNSS and LPS and a substantial number of investigated parameters. The majority of the validation studies have employed relatively simple field-based research designs, with use of measure tape/known distance as reference measure for distance. Timing gates and radar guns were frequently used as reference system for average and peak speed. Fewer studies have used reference system that allow for validation of instantaneous dynamic position, such as infrared camera-based motion capture systems. CONCLUSIONS: Because most validation studies use simple and cost-effective reference systems which do not allow to quantify the exact path athletes travel and hence misjudge the true path length and speed, caution should be taken when interpreting the results of validation studies, especially when comparing results between studies. Studies validating instantaneous dynamic position-based measures is warranted, since they may have a wider application and enable comparisons both between studies and over time.

Match Demands of Women's Collegiate Soccer.

Research describing the match and specific positional demands during match play in women's collegiate soccer is limited. The purpose of the study was to quantify the match demands of National Collegiate Athletic Association (NCAA) Division III soccer and assess position differences in movement kinematics, heart rate (HR), and energy expenditure. Twenty-five Division III women soccer players (height: 1.61 ± 0.3 m; body mass: 66.7 ± 7.5 kg; fat-free mass: 50.3 ± 6.5 kg; body fat%: 25.6 ± 5.1%) were equipped with a wearable global positioning system to assess the demands of 22 matches throughout a season. Players were categorized by position (goal keepers (GK), center defenders (CB), flank players (FP), forwards (F), and center midfielders (CM)). Players covered 9807 ± 2588 m and 1019 ± 552 m at high speeds (>249.6 m·m-1), with an overall average speed of 62.85 ± 14.7 m·m-1. This resulted in a mean HR of 74.2 ± 6% HR max and energy expenditure of 1259 ± 309 kcal. Significant and meaningful differences in movement kinematics were observed across position groups. CM covered the most distance resulting in the highest training load. FP covered the most distance at high speeds and mean HR values were highest in CM, CB, and FP positions.

Physiological Demands of Trampolining at Different Intensities.

Purpose: The aim of this study was to examine the physiological demands of trampolining, in comparison with treadmill running, using a larger sample size and a wider range of physiological measures, than had been reported in the previous research. Method: Twenty-three healthy adults completed three, three-minute exercise bouts on both a trampoline and treadmill at different intensities. Heart rate (HR), oxygen consumption ([Formula: see text]), energy expenditure (EE) and blood lactate (BL) were collected for each bout. Results: Results of a two-way repeated measures MANOVA indicated that there was a significant difference between the modalities ([Formula: see text] = 9.3, p <.0005, [Formula: see text] = 0.39). A follow up two-way repeated measures ANOVA then identified that significant differences existed between the modalities for each of the variables; [Formula: see text] ([Formula: see text] = 159, p <.0005, [Formula: see text] = 0.88), EE (= 136, p <.0005, [Formula: see text] = 0.86) and BL ([Formula: see text] = 171, p <.0005, [Formula: see text] = 0.89). Subsequent post hoc testing found [Formula: see text] to differ significantly between the medium intensities (p =.01 d =0.6). EE to differ significantly for the medium (p =.003, d =-0.7) and high intensities (p =.02, d =-0.5). BL to differ significantly for the low (p =.04, d =0.4), medium (p =.03, d =0.5) and high (p =.001 d =1.4) intensities. Conclusions: The results from our study indicated that while significant differences do occur between running and trampolining for a given intensity, the trendline associated with each of the variables is similar. Therefore, monitoring the intensity of the session based the percentage of the participant's maximum heart rate, which is commonly used in running, may also be applied to trampolining.

Validity and Reliability of a New Specific Parkour Test: Physiological and Performance Responses.

Main aim of this study was examining validity and reliability of using a new specific Parkour repeated sprint ability test (SPRSA) for assessing repeated sprint ability while facing obstacles and establishing between-day reliability and sensitivity of SPRSA related to its physiological and performance responses. Thirteen high-level traceurs (three females) performed in random order and twice eight tests for assessing a total of 23 variables: SPRSA (a typical maximal-speed shuttle run interspersed with four Parkour competition-common fundamentals) and seven established fitness tests, core stability, hand-grip, vertical-jump, long-jump, pull-up, 300-m shuttle run (as a field test for anaerobic capacity), and Leger test. Except for muscular elasticity index of vertical jump test (intra-class Correlation Coefficient model 3,1 [ICC3,1] = 0.54 [fair]), fitness tests' ICC3,1s resulted excellent (ICC3,1: 0.93-1.00). SPRSA total time and time of its fastest sprint (SPRSA peak time) were significantly correlated with the majority of core stability (r: -0.79 to 0.59; P < 0.01-0.05), jumping (r: -0.78 to 0.67; P < 0.01-0.05), pull-up tests (r: -0.86; P < 0.01), 300-m shuttle run test total time (r: 0.77-0.82; P < 0.01), and Leger test-estimated VO2 max (r: -0.78; P < 0.01). Principal component analysis (PCA) of the 23 variables led to extraction of four significant components (each due to different variables' combinations), which explained 90.2% of 23 variables' total variance. SPRSA (i.e., total and peak time) showed high reliability (ICC3,1: 0.991-0.998 and standard-error-of-measurement %: 0.07-0.32). Finally, SPRSA showed high sensitivity (smallest-worthwhile-change %: 0.29-0.68). Considering its excellent logical and strong ecological validity, SPRSA may serve as a valid specific field test for Parkour sport. In addition, thanks to its high reliability and sensitivity, this test is suitable for monitoring, evaluating, and programming training processes for Parkour practitioners in repeated sprint ability involving crossing obstacles.
