Compression Stockings Used During Two Soccer Matches Improve Perceived Muscle Soreness and High-Intensity Performance.

ABSTRACT: Gimenes, SV, Marocolo, M, Pavin, LN, Pagoto Spigolon, LM, Neto, OB, Côrrea da Silva, BV, Duffield, R, and Ribeiro da Mota, G. Compression stockings used during two soccer matches improve perceived muscle soreness and high-intensity performance. J Strength Cond Res 35(7): 2010-2017, 2021-Evidence on the use of compression stockings (CS) during soccer matches is limited. Thus, we evaluated the acute effects of CS on match-based physical performance indicators and perceptual responses during 2 consecutive soccer matches with 72-hour recovery. Twenty outfield players were randomly allocated to the CS group (20-30 mm Hg) or control group (non-CS) and performed 2 matches (5 players using CS or regular socks per team/match). Match loads {rating of perceived exertion × minutes; CS ∼830 vs. control 843 (arbitrary units [AU])} and heart rate (HR) responses (both CS and control ∼86% HRpeak) did not differ (p > 0.05) between CS and control groups. Although total distance covered did not differ (p > 0.05) between groups, CS increased distances (effect size [ES] = 0.9-1.32) in higher-speed zones (>19 km·h-1 CS ∼550 m vs. control ∼373 m) alongside an increased number of accelerations (-50.0 to -3.0 m·s-2) than control (CS: 33.7 ± 11.2 vs. control: 23.8 ± 7.9; p = 0.003; ES = 1.04). Perceived recovery did not differ (p > 0.05) between groups for either match but was worse in the second match for both groups. Perceived muscle soreness increased in control after match 2 (from 3.1 ± 1.9 to 6.3 ± 1.6 AU; p < 0.0010) but did not in CS (from 2.8 ± 1.4 to 4.1 ± 1.9 AU; p = 0.6275; ES = 1.24 CS vs. control after match). Accordingly, CS use during 2 soccer matches with 72-hour recovery reduces perceived muscle soreness in the second match and increases higher-speed match running performance.

Can compression stockings reduce the degree of soccer match-induced fatigue in females?

Soccer-induced fatigue and performance are different between the sexes. The effect of compression stockings (CS) use on fatigue during the soccer match in females is unknown. Thus, we evaluated the impact of CS use during a female soccer match on match-induced fatigue. Twenty soccer players were randomly allocated to two groups (n = 10 for each group): CS and Control (regular socks), and equally distributed within two teams. At rest (baseline 48-h before the match) and immediately post-match, we assessed agility T-test, standing heel-rise test and YoYo Intermittent Endurance Test level 2 (YoYoIE2) performance. Effort during the match (heart rate and rating of perceived exertion) was similar (p > 0.05) between groups. The YoYoIE2 performance was decreased post-match (p < 0.05) equally for both groups. Otherwise, the CS group exhibited a greater post-match performance (p < 0.05) for the agility T-test and heel-rise test (large effect sizes). Therefore, we conclude that the use of CS during an amateur female soccer match resulted in less match-induced fatigue.

Principles of core stability in the training and in the rehabilitation: review of literature / Princípios da estabilidade de core no treinamento e na reabilitação: revisão da literatura

The core stability is defined as the ability of the lumbopelvic complex to control the position and motion of the trunk after perturbation, allowing the transfer and the control of strength to the segments during activities. The stability is predominantly maintained by the dynamic function of muscular groups, besides the contribution of the static elements, and it has been suggested that his decrease may contribute to the lower members injuries' etiology. The objective of this article is to review in literature the current findings of this theory in rehabilitation and training and its principles. It follows that the core's acquisition and maintenance stability is of great interest to physical biomechanics and it must be incorporated in the rehabilitation and physical training programs.

A estabilidade de core é definida como a habilidade do complexo lombo pélvico em controlar a posição e o movimento do tronco após perturbação, permitindo a transferência e o controle de força para os segmentos durante as atividades. A estabilidade é predominantemente mantida pela função dinâmica dos grupos musculares, além da contribuição dos elementos estáticos, e tem sido sugerido que seu decréscimo pode contribuir para a etiologia das lesões dos membros inferiores. O objetivo deste artigo é rever na literatura os achados atuais desta teoria na reabilitação e no treinamento e seus princípios. Conclui-se que a aquisição e manutenção da estabilidade de core é de especial interesse para a biomecânica corporal e deve ser incorporada nos programas de reabilitação e treinamento físico.
