This study reports on the content and periodisation of the preseason field-based training for a professional rugby league team. Thirty professional male rugby league players (26 ± 5 years, 180.9 ± 6.5 cm, 94 ± 9 kg) completed an 8-week preseason. Global positioning system devices and heart rate were used to monitor physical and physiological responses of different field-based training components (speed, conditioning, rugby skill and game-based training). Rugby skill training contributed the most to the total distance covered, conditioning was the greatest contributor to high-speed running (>15 km/h) and game-based training provided the greatest high metabolic distance (>20 W/kg) and overall external load. Game-based training provided the greatest time with heart rate ≥80% estimated maximum. The weekly preseason cycle had lower loads on Monday and Thursday whereas Tuesday and Friday produced the highest loads. The preseason described herein adopted a progressive overload comprising a weekly undulating cycle. This study emphasises how skill and games-based training contributes significantly to the overall load of a professional rugby league team's preseason with more traditional conditioning promoting high-speed running load and high metabolic load.

The purpose of this study is to present a comparison of the workload demonstrated by young soccer players during the phases of warm-up (WU), first half (FH) and second half (SH) of a league match. Eleven young Polish soccer players took part in this research, playing a league match after completing the WU. During the WU, FH and SH of the match the following variables were recorded: total distance run, maximal and average speed achieved during the runs, number of sprints, distances run in the different speed zones, durations of increased heart rate (HR) in specific ranges, and the maximal, mean and minimal HR. The variables were recorded by means of the Global Positioning System (GPS). The research showed that there were significant differences between the WU, FH and SH in the total distances run (F=30.107, p<0.001), the average speed achieved during the runs (F=37.731, p<0.001), the distances run at different speeds (p<0.001), the duration of increased HR in specific zones, and HRmean (p=0.002) and HRmin (p<0.001). Post hoc analysis confirmed that, for the majority of the analyzed parameters, the WU provided a smaller load for the body than did the FH or SH, the intensity of which in some part was higher than that encountered at the anaerobic threshold. In conclusion, it has been shown that the WU and the two halves of the match load the body to varying degrees, the former doing so to a lesser extent than FH or SH.

The aim of the present study was to analyse load to which players were exposed to and effort they invested in 4vs4 small-sided handball games in relation to various court dimensions. Eight male amateur handball players participated in three eight-minute 4vs4 (plus goalkeepers) small-sided handball games. The three court dimensions were 12×24 m, 30×15 m and 32×16 m. Using Global Positioning System devices (SPI pro elite 15hz, GPSports), time-motion video analysis, and Borg’s scale for rating of perceived exertion (RPE), the following performance, physiological and psychological parameters were recorded: cyclic movements for distance covered, acyclic movements for the number of technical actions executed, heart rate, and RPE. Total distance travelled increased with the increase in court size (948.1±64.5, 1087.2±92.0 and 1079.8±90.6 on the 24×12 m, 30×15 m and 32×16 m court, respectively; p&lt;.05). Distance covered by the players in four speed zones revealed the substantial difference between the games played on the 24×12 and 30×15m court in the first and third (p&lt;.05; moderate ES) speed zone. On the 24×12 m court players covered more distance while moving in the first speed zone, but less distance when moving in the third speed zone (p&lt;.05; moderate ES). On the 32×16 m court the players covered less distance while moving in the first speed zone, but they covered more distance by moving in the third speed zone (p&lt;.05; moderate ES). There were no substantial differences found for the second and fourth speed zone cyclic movements and distances covered on all the three experimental court sizes. No statistical differences between the games played on various court dimensions were found in acyclic movements. No statistical differences were found in the analysis of heart rate. Further analysis of players’ self-evaluated effort confirmed the trend of heart rate values, showing no statistical differences in the RPE values among the three different court dimensions. Our findings indicate that changing court dimensions during 4vs4 small-sided handball games could influence load imposed on the players and their exertion.

The purpose of this paper was to compare two small-sided games kinematics of Costa Rican college soccer players. Two SSG (2x10min, 3 min rest in between), C1 (600m2) and C2 (1200m2), were played by 14 college soccer players of Costa Rica. Global Positioning System was used to measure kinematic and physiological variables in both conditions. A mixed ANOVA was used, results suggested C1 and C2 were statistically different in speed (C1 < C2), distance (C1 < C2) and heart rate (C1 > C2). When analyzing the distance covered by speed category (low, moderate and high running actions) results suggest C2 had higher intensities compared to C1. This research confirms the findings of previous studies on the effectiveness of SSG to simulate real game conditions in short periods of time. Conclusions: C2 had higher intensities compared to C1 game with lower physiological demand. Likewise, the C2 resembles more accurately matches in official conditions of Costa Rican players.

The primary aim was to assess the test–retest reliability of an outdoor walking test with a global positioning system device in older women in a community setting. In addition, correlations between the suggested test and various tests recommended to evaluate muscle strength, walking speed, and self-perceived health status in older adults were studied. The study included 40 women aged 68 (SD = 5) years. The primary outcomes were total walked distance and mean walking speed. The secondary outcomes were lower-body strength, heart rate, speed in a 4-m walk test, and self-perceived health status. The intraclass correlation coefficients calculated for the total walked distance, mean walking speed, and mean heart rate were .94, .92, and .37, respectively. Thus, the suggested outdoor walking test with the application of a global positioning system device may be considered a reliable test tool, which can be recommended for the evaluation of walking ability among older women in a community setting.

Purpose:The aim of this study was to develop a laboratory-based treadmill simulation of the on-course physiological demands of an 18-hole round of golf and to identify the underlying physiological responses.Methods:Eight amateur golfers completed a round of golf during which heart rate (HR), steps taken, and global positioning system (GPS) data were assessed. The GPS data were used to create a simulated discontinuous round on a treadmill. Steps taken and HR were recorded during the simulated round.Results:During the on-course round, players covered a mean (±SD) of 8,251 ± 450 m, taking 12,766 ± 1,530 steps. The mean exercise intensity during the on-course round was 31.4 ± 9.3% of age-predicted heart rate reserve (%HRR) or 55.6 ± 4.4% of age-predicted maximum HR (%HRmax). There were no significant differences between the simulated round and the on-course round for %HRR (P = .537) or %HR max (P = .561) over the entire round or for each individual hole. Furthermore, there were no significant differences between the two rounds for steps taken. Typical error values for steps taken, HR, %HRmax, and %HRR were 1,083 steps, ±7.6 b·min-1, ±4.5%, and ±8.1%, respectively.Conclusion:Overall, the simulated round of golf successfully recreated the demands of an on-course round. This simulated round could be used as a research tool to assess the extent of fatigue during a round of golf or the impact of various interventions on golfers.
