Recreation

Purpose: To purpose of this study was to quantify and compare the internal and external load imposed on players during 3-, 4-, and 5-aside recreational football and handball games, as well as 1-, 2-, and 3- a-side recreational basketball games. Methods: Recreationally active, male college students were monitored across 2 x 20 min of 3-, 4-, 5-a-side football and handball games, and 10 min of 1-, 2- and 3-a-side basketball small-sided games (SSG). Internal load variables included continuous measurement of heart rate (HR) responses, as well as blood lactate concentration (BLa) and rating of perceived exertion (RPE) following each game. External load variables included measurement of the total distance covered as well as the frequency of accelerations and decelerations. Results: Football. Mean HR was higher during 5-a-side (85.4 ± 6.3% HRmax) than 4-a-side (81.5 ± 9.3% HRmax, p = 0.05, small) and 3-a-side SSG (80.9 ± 7.1% HRmax, p < 0.001, moderate). In contrast, BLa tended to be higher in 3-a-side (5.2 ± 1.6 mmol·L-1) than in 4-a-side (4.4 ± 1.1 mmol·L-1, p = 0.12, moderate). No significant differences in RPE (3- a-side: 5.5 ± 1.8, 4-a-side: 5.0 ± 2.1, 5-a-side: 5.0 ± 1.5) were observed between game formats. The total distance covered was lower during 5-a-side than 4-a-side SSG (p = 0.02, large), while the total number of accelerations (p = 0.01, large) and decelerations (p = 0.02, large) were higher during 5-a-side than 4-a-side SSG. Handball. No significant differences in relative mean HR (3-a-side: 84.8 ± 5.2% HRmax, 4-a-side: 81.7 ± 6.4% HRmax, 5-a-side: 82.3 ± 8% HRmax), and BLa (3-a-side: 4.4 ± 1.3 mmol·L-1, 4-a-side: 4.4 ± 1.5 mmol·L-1, 5-a-side: 3.9 ± 1.6 mmol·L-1) were observed between game formats. A significant effect was observed for RPE in which 3-a-side elicited higher RPE (p = 0.03, large) than 5-a-side game formats. In addition, no significant differences in total distance, total accelerations, and decelerations were observed between game formats. Basketball. No significant differences in relative HR (1-a-side: 88.4 ± 5.4% HRmax, 2-a-side: 87.8 ± 5.6% HRmax, 3-a-side: 86.1 ± 5.8% HRmax) were observed between game formats. BLa and RPE were greater in 1-a-side SSG than 3-a-side SSG (BLa: p = 0.01, moderate; RPE: p = 0.004, moderate). Total accelerations and decelerations were higher in 1-a-side (accelerations: p = 0.03, moderate; decelerations: p = 0.002, large) and 2-a-side (accelerations: p = 0.02, large; decelerations: p = 0.003, large) compared to 3-a-side SSG. Conclusion: Football, handball and basketball elicits activity intensities that can improve cardiovascular health and fitness in the general population when administered in recreational settings. Football. The number of players competing in SSG affected the physiological responses and activity demands encountered by players with the highest HR as well as acceleration and deceleration demands evident during 5-a-side games. In addition, the 4-a-side game format imposed a greater overall volume of activity, while the 3-a-side game format resulted in higher BLa compared to other formats. Handball. Our findings suggest overlap in physiological and activity demands across 3-, 4-, and 5-a-side game formats. Basketball. Recreational basketball SSG with only 1 player per team elicits higher BLa, RPE, distances covered at low speeds, as well as acceleration and deceleration volumes than format with 3 players per team.
