Effects of Pre-Season Short-Term Daily Undulating Periodized Training on Muscle Strength and Sprint Performance of Under-20 Soccer Players

Purpose: The aim of the study was to investigate the effect of linear and undulating strength-power training scheme on the repeated sprint ability (RSA) and lower body strength of soccer players. Method: Twenty soccer players (under-20 category) were split into 2 groups: the linear load (LL, n=10) and the undulating load (UL, n=10). In the commencement and at the end of the 6-week pre-season period, the RSA test (6 x 35m) and the 1RM parallel squat test (1RM squat ) were conducted. The LL and UL performed the same type and number of sessions. The training stimulus in the strength training was different between LL (Weeks 1 and 2 = Muscular Endurance; Weeks 3 and 4 = Strength; Weeks 5 and 6 = Power) and UL (daily load variation in the same week). Results: A improvement in RSA mean and 1RM squat was detected in LL and in UL. No significant difference was noted between LL vs UL for all variables. Conclusion: Both groups improved maximal muscle strength in parallel back squat and RSA. UL induced a greater gain in RSA.

ResumoObjetivo: Avaliar o efeito agudo de um jogo simulado de futsal sobre o desempenho intermitente de alta intensidadee indicadores fisiológicos em futebolistas amadoras. Métodos: Dezesseis futebolistas (22,5 ± 1,7 anos)realizaram o teste YoYoIntermitenteEndurance 2 (YoYoIE2) em duas situações distintas (em dias separados por 48-h): baseline (descansadas e recuperadas) e logo após jogo amistoso de futsal. Resultados: A distância percorrida no YoYoIE2 na baseline foi de118,8 ± 4,6 m e, logo depois do jogo, foi de71,2 ± 5,4 m (queda de ~40%; p<0,05, tamanho do efeito = 9,5). Logo após o jogo, indicadores de intensidade relativa aumentaram (p<0,05) (Frequência cardíaca [FC] média/recuperação e percepção de esforço) em comparação com o YoYoIE2 basal -exceto FCpico.Conclusão: O desempenho intermitente de alta intensidade (YoYoIE2) é fortemente reduzido por uma partida simulada de futsal e variáveis associadas a intensidade interna bem como a recuperação aguda são prejudicadas pelo jogo. Portanto, YoYoIE2 é sensível para detectar alterações físicas agudas em futebolistas amadoras.Palavras-chave: desempenho, fadiga, futsal. AbstractObjective: To evaluate the acute effect of a simulated futsal game on high-intensity intermittent performance in amateur soccer players. Methods: Sixteen female soccer players (22.5 ± 1.7 years) performed the YoYo Intermittent Test Endurance Test 2 (YoYoIE2) on two distinct days (48-h apart): baseline (rested and recovered) and just after a friendly futsal game. Results: The distance covered in YoYoIE2 in the baseline was of 118.8 ± 4.6 m and just after the game 71.2 ± 5.4 m (~40% drop; p<0.05, effect size = 9.5). Just after the game, relative intensity indicators increased (p<0.05) (Heart rate [HR] mean/recovery and perceived exertion) in comparison with baseline YoYoIE2-except HRpeak. Conclusion: Intermittent high-intensity performance (YoYoIE2) is strongly reduced by a simulated game of futsal and variables associated with internal intensity as well as acute recovery are impaired by the game. Therefore, YoYoIE2 is responsive to detect acute physical changes in amateur soccer players.
