“…Data on players' HR was collected during all SSGs. The individual minimum HR was noted by the participants (each morning in bed for five consecutive days), and this data, together with the maximum HR obtained at the end of the 30-15 Intermittent Fitness Test, was used in the Karvonen formula (HR(%)=[100*(HR-HRmin)]/[HRmax-HRmin]) to calculate the HR reserve (Duarte, et al, 2010). The reference scale was as follows: <50%, 50-70%, 70-90% and >90% of the relative HR reserve.…”

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<.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<.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<.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<.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 wag for defeating the opponent is strong and precise attacking with shots and throws from a distance forced by the rules. In additionusing a real size goals gives some stimulation and motivation to the players and these rules let reduce the random effects (Duarte et al, 2010).…”

Small-sided soccer games, i.e. 1v1 are often used in training, which results in a composite influence on the player. Training exercises stimulated in the game allow to master many skills, form habits and modify behaviors associated with solving specific situations during a match. The aim of the study was to assess the intensity of exercise during a 1v1 game for goalkeepers. Eight goalkeepers participated in the experiment (body weight 80.63 ±3.50 kg, body height 184.69 ±3.71 cm, BMI 23.64 ±0.74). All goalkeepers played 1v1 games. During the small-sided game players can use all the goalkeeper techniques to score a goal. During all of the matches, heart rate (HR) was recorded using a sport tester, LA was measured in the second minute after the end of each game. There was also collected data determining subjective assessment of the effort made by the players using Borg scale (RPE). The highest average HR and RPE were recorded in the third match, respectively (192.38 ±8.07 b/min; 14.38 ±2.07), while in the first match the examined parameters were on average 186 ±8.85 b/min; 11.38 ±1.51, and in the second 186.00 ±8.09 b/min; 13.50 ±1.85 respectively. The highest LA level was recorded after the second match and equaled 7.71 ±2.07 mmol/l (7.06 ±3.54 after the first match and 7.5 ±1.37 after the third match). The 1v1 game requires the use of similar to the real game actions, as well as the average exercise intensity is also similar to the scoringopportunity situations and conditions of a match.

“…Other task conditions have also been studied such as the limitations of individual contacts on ball location (Dellal, Lago-Penas, Wong, & Chamari, 2011), goals (Duarte, et al, 2010), the non-use of goalkeepers (Mallo & Navarro, 2008) and the use of neutral players (Evangelos et al, 2012). From those task conditions, it was found that the limitations of touches per player, the non-use of goalkeepers or the non-use of goals increased the heart rate responses of soccer players.…”

Abstract-The aim of this study was to inspect the effects of format and task conditions on neutral players' heart rate responses and time-motion characteristics. Four formats of play using neutral players and three task conditions were inspected. Moreover, the factor repetition (3 games per each SSG) was also analysed. Ten male amateur soccer players (26.36 ± 5.33 years old, 8 ± 3.2 years of practice, 66.18 ± 10.16 bpm at rest) participated in this study. The repeated measured revealed that no differences were found between repetitions (Pillai's Trace = .075; F 8, 100 = 1.007; p-value = .436; = .075; Power = .445; small effect size). In the game 1 significant interaction effects between the two factors on heart rate responses and time-motion profiles were observed (Pillai's Trace = 0.699; F 24,428 = 3.774; p-value = .001; = .175; Power = 1.000; moderate effect size). In the game 2 , significant interaction effects between the two factors on heart rate responses and time-motion profiles were observed (Pillai's Trace = .712; F 24,428 = 3.860; p-value = .001; = .178; Power = 1.000; moderate effect size). Finally, in the game 3 significant interaction effects between the two factors on heart rate responses and time-motion profiles were observed (Pillai's Trace = .729; F 24,428 = 3.972; p-value = .001; = .182; Power = 1.000; moderate effect size). Briefly, it was possible to conclude that the biggest formats statistically increased the heart rate responses and time-motion characteristics of neutral players. It was also possible to observe that the mean values of heart rate responses found in neutral players throughout small-sided games were appropriated to very light or recovery workouts.Keywords: soccer, small-sided games, task conditions, performance, neutral players Resumo-"Avaliando o desempenho de jogadores neutros em diferentes jogos reduzidos." O objetivo deste estudo foi avaliar os efeitos do formato e condições da tarefa nas respostas cardíacas e perfis de movimento de jogadores neutros. Adotaram-se quatro formatos de jogo e três condições da tarefa utilizando jogadores neutros. Participaram no estudo dez jogadores de futebol amador (26,36 ± 5,33 anos de idade, 8 ± 3,2 anos de prática, 66,18 ± 10,16 bpm em descanso). O teste de medidas repetidas não mostraram diferenças estatisticamente significativas entre repetições (Pillai's Trace = 0,075; F 8, 100 = 1,007; p-value = 0,436; = 0,075; Power = 0,445). No jogo 1 identificaram-se diferenças estatisticamente significativas na interação entre factores nas variáveis de frequência cardíaca e velocidade (Pillai's Trace = 0,699; F 24,428 = 3,774; p-value = 0,001; = 0,175; Power = 1,000). No jogo 2 identificaram-se diferenças estatisticamente significativas na interação entre factores nas variáveis de frequência cardíaca e velocidade (Pillai's Trace = 0,712; F 24,428 = 3,860; p-value = 0,001; = 0,178; Power = 1,000). Finalmente, no jogo 3 identificaram-se diferenças estatisticamente significativas na interação entre factores nas variáveis de frequência cardíaca e vel...
