Data Collection Approach

This dataset provides information pertaining to the spatiotemporal stresses experienced by Polo ponies in play and the cardiovascular responses to these demands by Polo players, during 16-goal Polo. Data were collected by player-worn GPS units and paired heart rate monitors, across a New Zealand Polo season. The dataset comprises observations from 160 chukkas of Open Polo, and is presented as per chukka per game (curated) and in per effort per player (raw) formats. Data for distance, speed, and high intensity metrics are presented and are further categorised into five equine-based speed zones, in accordance with previous literature. The purpose of this dataset is to provide a detailed quantification of the load experienced by Polo players and their ponies at the highest domestic performance level in New Zealand, as well as advancing the scope of previous Polo literature that has employed GPS or heart rate monitoring technologies. This dataset may be of interest to equine scientists and trainers, veterinary practitioners, and sports scientists. An exemplar template is provided to facilitate the adoption of this data collection approach by other practitioners.

Despite the importance of regaining independent ambulation after stroke, the amount of daily walking completed during in-patient rehabilitation is low. The purpose of this study is to determine if (1) walking-related heart rate responses reached the minimum intensity necessary for therapeutic aerobic exercise (40%–60% heart rate reserve) or (2) heart rate responses during bouts of walking revealed excessive workload that may limit walking (>80% heart rate reserve). Eight individuals with subacute stroke attending in-patient rehabilitation were recruited. Participants wore heart rate monitors and accelerometers during a typical rehabilitation day. Walking-related changes in heart rate and walking bout duration were determined. Patients did not meet the minimum cumulative requirements of walking intensity (>40% heart rate reserve) and duration (>10 minutes continuously) necessary for cardiorespiratory benefit. Only one patient exceeded 80% heart rate reserve. The absence of significant increases in heart rate associated with walking reveals that patients chose to walk at speeds well below a level that has meaningful cardiorespiratory health benefits. Additionally, cardiorespiratory workload is unlikely to limit participation in walking. Measurement of heart rate and walking during in-patient rehabilitation may be a useful approach to encourage patients to increase the overall physical activity and to help facilitate recovery.

Monitoring fatigue and performance is important for adjusting training loads in soccer. Therefore, knowing the status of the player when applying a training stimulus is key to optimizing the players’ development. This study aims to evaluate the interaction between internal and external load, during training and matches, in an elite youth soccer team. Methods: seventeen youth players of the highest Spanish category were monitored with GPS devices during training and matches, as well as recording their nocturnal heart rate variability (HRV). We employed a linear mixed model to assess the physical demands between training and matches, and to compare the HRV variables. Results: a higher total distance (+2993.35–5746.56 m; ES = 1.4), distance at high intensity (+641.24–1907 m; ES = 1.5), sprint distance (+350.46–795.05 m; ES = 2.1), number of sprints (+18.38–41.58; ES = 1.9), and number of repeated sprints (+5.91–15.30; ES = 1.7) (all p < 0.001), but not in the number of accelerations, were reported during the matches when compared to the training sessions during the 11 weeks. The analysis of the HRV variables showed no significant differences between the accumulated values during a training week, providing similar results pre-match or post-match (p > 0.05). The LF/HFRATIO showed a negative influence on the total distance ran, distance at high intensity, distance in sprint, number of sprints, and repeated sprint. RRMEAN was positively related to the sprint number. Conclusion: the results of the present study suggest that nocturnal HRV variables are not different between pre-match and post-match. Furthermore, it suggests that LF/HFRATIO and RRMEAN during pre-match can determine the external load that the player will be able to complete during the match.

Background:This study validated the short- and long-form New Zealand Physical Activity Questionnaires (NZPAQ-SF and NZPAQ-LF) against heart-rate monitoring (HRM) with individual calibration.Methods:A multiethnic sample (N = 180), age 19 to 86 y, underwent HRM for 3 consecutive days while simultaneously completing physical activity (PA) logs.Results:Both NZPAQs showed significant (p < .001) correlations to HRM data for brisk walking (r = .27–.43), vigorous-intensity PA (r = .27–.35), and total PA (r = .25; 95% CI, 0.10-0.40), whereas moderate-intensity PA was substantially overreported (mean = 157-199 min). Although the NZPAQ-LF performed better for brisk walking and vigorous-intensity PA, the NZPAQs were strongly correlated (r = .61 and r = .52, respectively, p < .0001). European/Other participants demonstrated the most accurate PA recall of total PA on both NZPAQs (r = .36−.41, p < .01).Conclusions:The NZPAQs are acceptable instruments for measuring adult PA levels and produce similar results. Substituting culturally specific examples of PAs on the NZPAQs and their accompanying show cards could potentially improve PA recall for Maori and Pacific people.

AbstractThe aim of the present study was to examine the relationship between different kinds of intensity indicators in small-sided soccer games. This descriptive correlational study included 14 semi-professional male soccer players (21.3 ± 2.3 years, 174 ± 4.0 cm, 73.4 ± 5.1 kg) from the same team. The players were monitored by means of heart rate monitors and GPS devices during 27 small-sided games of nine different formats, yielding a total of 217 recordings. After each game the Borg scale was used to give a rate of perceived exertion (RPE). The internal load indicators were the mean heart rate relative to the individual maximum (%HRmean) and the RPE, while those for the external load were the player load, total distance covered, distance covered in two intensity ranges (>18 km·h-1 and >21 km·h-1), and frequency of effort (in the same two intensity ranges). There was a significant moderate correlation (r=0.506) between the two internal load measurements (%HRmean and RPE). Although there were significant correlations of different degrees between various external load measurements, only the player load was significantly correlated with the internal load indicators (r=0.331 with %HRmean and r=0.218 with RPE). During training programes of this kind, it is necessary to consider a range of intensity indicators so as to obtain complementary information. This will enable coaches to more accurately assess the load imposed on players and therefore optimize the training process.

  El objetivo principal de esta investigación es cuantificar la carga externa y la carga interna en tres tipos de entrenamiento (cubos con la mano, cubos con raqueta y peloteos) más utilizados en el ámbito del tenis de competición y compararlos entre sí. Participaron 6 jugadores de tenis (cuatro jugadores masculinos y 2 jugadoras) con una media de edad de 16.67 (± 2.73) años. Para cuantificar las cargas, se han utilizado pulsómetros POLAR +M400 para recoger los datos relacionados con la frecuencia cardíaca, distancia recorrida, velocidad media y máxima, y sensores ZEPP TENNIS, con los que se han recogido los datos relativos a tipo de golpe, número de golpeos y velocidad de raqueta en cada uno de los golpes realizados. Además, para registrar la percepción subjetiva de esfuerzo, en cada tarea realizada y al final de cada entrenamiento, se ha utilizado la Escala de Borg CR-10 (Borg, 1982). Se realizaron 9 sesiones de entrenamiento por parejas: tres para el entrenamiento del drive, tres para el entrenamiento del revés y tres para el entrenamiento del drive y el revés de forma conjunta, una para cada tipo de entrenamiento. Los resultados obtenidos muestran que el entrenamiento de cubos con la mano tiene mayor carga interna en cuanto a número de golpeos y velocidad media de raqueta, siendo el entrenamiento de peloteos el que mayor carga externa refleja en relación a velocidades y distancias recorridas. Abstract. The main objective of this research is to quantify the external load and the internal load in three types of training (buckets with the hand, buckets with racket and rallies) most used in the field of tennis and compare them to each other. Six tennis players participated (four male and two female players) with an average age of 16.67 (± 2.73) years. To quantify the loads, POLAR +M400 heart rate monitors were used to collect the data related to heart rate, distance covered, average and maximum speed, and ZEPP TENNIS sensors were used to collect the data related to type of stroke, number of strokes and racket speed for each of the strokes made. In addition, the Borg CR-10 Scale (Borg, 1982) has been used to record the rate of perceived exertion, in each task performed and at the end of each training session. Nine training sessions were carried out in pairs: three for drive training, three for backhand training and three for drive and backhand training together, one for each type of training. The results obtained show that bucket training with the hand has a greater internal load in terms of the number of strokes and average racket speed, with racket training having the greatest external load in relation to speed and distance travelled.

Children’S Physical Activity

Abstract: We monitored the physical activity levels of 42 children during a regular day in kindergarten, using various instruments. This study will provide knowledge about children’s activity levels in kindergarten. It also discusses whether children’s activity levels can be adequately evaluated by the teachers or if there is a need for technical measurements. In addition, we compared the different instruments used to evaluate the children. The employees in the kindergarten were asked to answer a questionnaire about the children’s physical activity level during the day, and a student or a researcher observed and registered one child each. During the same day, activity levels were monitored using actigraphy (AC; Actigraf GT3X) and continuous heart rate monitoring (HR; Team2 Polar ®) in 14 children (six boys and eight girls, 38 and 47 months old, respectively). The researcher-observations defined the observed children as “moderately active”, and AC-data showed that all children had more than 60 minutes of moderate - or high - intensity activity. According to our comparisons, the use of HR to assess the activity in kindergartens is not recommended. On average, the questionnaires reported similar physical activity levels for the same child, although the evaluations varied between employees. When comparing one active and one inactive child, the different methods showed similar results. We conclude that professionals can see a child’s physical activity level when asked to reflect upon it.Sammendrag: Vi målte det fysiske aktivitetsnivået til 42 barn i løpet av en vanlig dag i barnehagen ved hjelp av ulike instrumenter. Denne studien vil gi kunnskap om barns fysiske aktivitet i barnehagen, og om barnas aktivitetsnivå kan bli tilstrekkelig evaluert av lærerne eller om det er behov for tekniske målinger. Videre har vi sammenlignet de ulike instrumentene brukt i observasjonen. De ansatte i barnehagen ble bedt om å svare på et spørreskjema om barns fysiske aktivitetsnivå i løpet av dagen, og en student eller forsker observerte og registrerte ett barn hver. I løpet av samme dag, ble aktivitetsnivået overvåkt ved hjelp av actigraphy (AC; Actigraf GT3X) og kontinuerlig pulsmåling (HR, Team2 Polar ®) blant 14 barn (seks gutter og åtte jenter, 38- og 47-måneder gamle, henholdsvis). Forsker-observasjonene definerte de observerte barna som "moderat aktiv", og AC-data viste at alle barna hadde mer enn 60 minutter aktivitet med moderat eller høy intensitet. Våre sammenligninger viser at bruk av HR for å vurdere aktiviteten i barnehager er ikke anbefalt. I gjennomsnitt rapporterte spørreskjemaene lignende aktivitetsverdier for det samme barnet, selv om evalueringene varierte mellom ansatte. Når man sammenlignet et aktivt og et inaktivt barn, viste de ulike metodene lignende resultater. Vi konkluderer derfor at ansattes faglige blikk kan se barns fysiske aktivitetsnivå når de blir bedt om å vurdere det.

As most existing studies in youth academies are focused on top players, the objective of this research is to analyze the physical and physiological demands of various small-sided games (SSGs) on different age categories within a sub-elite soccer academy. We evaluated 63 young players from a Spanish sub-elite academy (under 14 = 21; under 16 = 21; under 18 = 21). Players performed four different small-side games focused on possession game (3-a-side; 4-a-side; 5-a-side; 6-a-side). The global indicators of performance and high-intensity actions were recorded through global positioning systems, whereas the heart rate responses were measured using heart rate monitors. Results: Under 16 ran a greater distance at high-intensity velocity than under 14 in the small side games 3v3 and 6v6. Furthermore, under 16 also ran a greater distance at high-intensity velocity than under 18 in the small side game 3v3 (p < 0.01). Under 14 showed greater acceleration at the highest intensity (> 2.75 m/s2) than the other age groups, under 16 and U18 (p < 0.01; ES (effect size) > 1). According to the physiological load, SSG 3v3 presented lower outcomes in Zone 6 (> 95% HRmax) than the small side game 4v4 and the small side game 5v5, in both under 14 and under 16. The workload of SSGs varies depending on the number of players, but also depending on the players’ ages. Therefore, when designing the SSGs it is important to consider both the players’ ages and the workload that want to be achieved.

  Los objetivos de este estudio fueron describir los niveles de actividad física (AF) en los escolares durante los recreos sin intervención, analizarlos en función del género y examinar la contribución de este tipo de recreo a las recomendaciones sobre intensidad de la AF en los recreos. Materiales y métodos. La muestra estaba compuesta por 32 alumnos (14 niños, 10,78±0,69; 18 niñas, 10,4±0,80) de un centro de Educación Primaria. La recogida de datos tuvo lugar durante 8 recreos y se emplearon pulsómetros Polar Team 2. Resultados y discusión. Los resultados muestran diferencias significativas en el nivel de AF en valores de intensidad de moderada a vigorosa (AFMV %) en función del género de los escolares, alcanzando los niños (63,25±23,15%) valores más altos que las niñas (43,74±26,00%). En cuanto a las recomendaciones de AF en los recreos, un porcentaje mayor de niños (81,33±6,20%) las alcanzan con respecto a las niñas (51,95±6,79%). Estos recreos contribuyen en un 24,79±7,01% con las recomendaciones de AF en valores AFMV diarias. Conclusiones. Los niveles de AFMV en los escolares durante el recreo son medios-bajos. Los niños participan durante el tiempo de recreo con una intensidad significativamente mayor que las niñas. Es necesario estudiar qué variables influyen en el aumento de los niveles de AF en valores AFMV en las niñas, las cuales se muestran más sedentarias.  Abstract: The goals of this study were to describe the levels of physical activity (PA) in children during recess without intervention, analyze them according to gender and examine the contribution of this type of recess to the recommendations on PA intensity during recess. Materials and methods. The sample consisted of 32 students (14 boys, 10,78 ± 0,69; 18 girls, 10,4 ± 0,80) from a Primary Education school. Data collection took place during 8 recess and Polar Team 2 heart rate monitors were used. Results and discussion. Results show significant differences in the level of PA in intensity values from moderate to vigorous (MVPA%) depending on the gender of the children, with boys (63,25 ± 23,15%) reaching higher values than girls (43,74 ± 26,00%). Regarding PA recommendations during recesses, a higher percentage of boys (81,33 ± 6,20%) reach them compared to girls (51,95 ± 6,79%). Recess contribute 24,79 ± 7,01% to the PA recommendations in daily MVPA values. Conclusions. MVPA levels in children during recess are medium-low. Boys participate during recess time with a significantly higher intensity than girls. It is necessary to study what variables influence the increase in PA levels in MVPA values in girls, who are more sedentary.
