Sangnier, S, Cotte, T, Brachet, O, Coquart, J, and Tourny, C. Planning training workload in football using small-sided games density. J Strength Cond Res 33(10): 2801-2811, 2019-To develop the physical qualities, the small-sided games' (SSGs) density may be essential in soccer. Small-sided games are games in which the pitch size, players' number, and rules are different to those for traditional soccer matches. The purpose was to assess the relation between training workload and SSGs' density. The 33 densities data (41 practice games and 3 full games) were analyzed through global positioning system (GPS) data collected from 25 professional soccer players (80.7 +/- 7.0 kg; 1.83 +/- 0.05 m; 26.4 +/- 4.9 years). From total distance, distance metabolic power, sprint distance, and acceleration distance, the data GPS were divided into 4 categories: endurance, power, speed, and strength. Statistical analysis compared the relation between GPS values and SSGs' densities, and 3 methods were applied to assess models (R-squared, root-mean-square error, and Akaike information criterion). The results suggest that all the GPS data match the player's essential athletic skills. They were all correlated with the game's density. Acceleration distance, deceleration distance, metabolic power, and total distance followed a logarithmic regression model, whereas distance and number of sprints follow a linear regression model. The research reveals options to monitor the training workload. Coaches could anticipate the load resulting from the SSGs and adjust the field size to the players' number. Taking into account the field size during SSGs enables coaches to target the most favorable density for developing expected physical qualities. Calibrating intensity during SSGs would allow coaches to assess each athletic skill in the same conditions of intensity as in the competition. [ABSTRACT FROM AUTHOR]

This study investigates the physiological/physical responses to a simulated mixed martial arts (MMA) competition over 24 hours. Twelve fighters performed a simulated MMA competition, consisting of three 5-minute MMA matches. Physiological/physical data were assessed before (Trest), directly after round 1 (Trd1), round 2 (Trd2) and round 3 (Trd3), and then 30 minutes (Trecovery30min) and 24 hours (Trecovery24h) post competition. Heart rate (HR), rating of perceived exertion (RPE), and blood lactate concentration ([La-]) were assessed at Trest, Trd1, Trd2, and Trd3. Biological data were collected at Trest, Trd3, Trecovery30min, and Trecovery24h. Physical tests were performed at Trest, Trecovery30min, and Trecovery24h. HR, RPE, and [La-] were high during competition. Leukocytes, hemoglobin, total protein, and glycemia were increased at Trd3 compared with all other time points (p ≤ 0.05). Cortisol was increased at Trd3 compared with Trest and Trecovery24h (p ≤ 0.05). Testosterone was higher at Trd3 and Trecovery30min than Trest (p < 0.001). Higher values of uric acid were noted during recovery periods (p < 0.001). Lactate dehydrogenase was lower at Trest compared with Trd3, Trecovery30min, and Trecovery24h (p ≤ 0.05). Countermovement jump was higher at Trest than Trecovery30min (p = 0.020). Consequently, MMA is a high-intensity intermittent combat sport that induces significant fatigue and muscle damage, both of which are still present at 24 hours post competition. [ABSTRACT FROM AUTHOR]
