- Effects of kettlebell swing training on cardiorespiratory and metabolic demand to a simulated competition in young female artistic gymnastsPublication . Melo, Xavier; Arrais, Inês; Marôco, João Luís; Ribeiro, Pedro Neto; Nabais, Sara; Coelho, Raquel; Reis, Joana; Angarten, Vítor; Fernhall, Bo; Santa-Clara, HelenaWe examined the effects of adding a Kettlebell Swing training program (KB) to the regular skill-training protocol (REGULAR) on cardiorespiratory fitness, cardiorespiratory/metabolic demand, and recovery to a simulated competition of female artistic gymnastics. Nine gymnasts (13±2 years) had their REGULAR complemented with a 4-week kettlebell training (REGULAR+KB), consisting of 3 sessions/week of 12x30” swings x 30” rest with ¼ of their body weight, while 9 aged-matched gymnasts acted as a comparison group. Peak oxygen uptake () during routines was estimated from the O2 recovery curve using backward extrapolation and off-kinetics parameters were modeled through a mono-exponential function. Heart rate (HR) was monitored continuously and capillary blood lactate (BLa-) was measured before and after each routine (1st and 3rd min). Cardiorespiratory fitness () was evaluated using a ramp cycle ergometer test. A training-by-time interaction effect was observed for (p = 0.009) as increments were only observed after REGULAR+KB (M = 8.85, SD = 9.67 ml.kg.min-1). No training-by-time interactions were observed for HRpeak (p = 0.39), (p = 0.07), or La-post3 (p = 0.25), both training protocols reduced HRpeak (M = -12; SD = 11 b.min-1) and BLa-post1 (M = -0.70; SD = 1.29 mmol.L-1) during the simulated competition, but not relative . No training-by-time interaction was observed for the off-transient time constant (p = 0.38). recovery was slower (M = 5; SD = 10 s) after both protocols. Both training protocols improved cardiorespiratory and metabolic demands and recovery kinetics to a simulated competition of female artistic gymnastics, although increases in cardiorespiratory fitness were only observed in REGULAR+KB.

- Seasonal changes in acceleration-speed profiles : insights from soccer players across diverse age groupsPublication . Cardoso, Pedro; Tavares, Francisco; Loureiro, Nuno; Ferreira, Ruben; Araújo, João Pedro; Gomes, João Sá; Reis, Joana; Vaz, João R.This study aimed to investigate the variation of the Acceleration–Speed (A-S) profile throughout one season in different age groups of elite young and professional soccer athletes. A total of 126 athletes from under-14 to B-team levels were analyzed in terms of their A-S profile, across a season divided in six training blocks. For all the blocks, we have calculated maximal theoretical acceleration (A0) and maximal theoretical speed (S0). Results revealed significant increases only in the S0 value for the under-15 age group (p < 0.05) during the season, while other age groups did not exhibit significant differences in the A-S profile over the same period. These findings emphasize the necessity of tailored training interventions to optimize acceleration and sprint capacities, particularly among younger players in the midst of physical development. Furthermore, the establishment of standardized norms tailored to different age groups based on these findings could facilitate the identification of outliers and inform individualized training strategies. This research could contribute to our understanding of the dynamic nature of sprinting performance and training demands in elite young soccer athletes, offering insights for optimizing performance outcomes and player development within soccer academies.
