Effects of carob rich-polyphenols on oxidative stress markers and physical performance in taekwondo athletes.

Excessive exercise can induce cell damage and impair muscle function by generating oxidative stress. Carob rich phenolic components have attracted the attention of many researchers because of their antioxidant actions. We utilized a double-blind randomized placebo-controlled design to study the putative antioxidant role of six weeks of daily polyphenol supplementation on selected blood markers of oxidative stress and performance in taekwondo athletes.

The effect of a sand surface on physical performance responses of junior male handball players to plyometric training.

Background: The effects of 7 weeks plyometric training on a stable surface and on sand were compared in junior male handball players.

Methods: A team of experienced players was divided randomly between three groups, undertaking a standard in-season regimen (C,  = 10), or supplementing this regimen by plyometric training on sand (PS,  = 11) or a stable surface (P, n = 10) for 7 weeks. Assessments included 20 m sprint times, change of direction tests (Modified change-of-direction T-test and Modified Illinois test), a repeated sprint T-test, jumping ability (squat, countermovement and five jump tests), and static and dynamic balance.

Field Tests of Performance and Their Relationship to Age and Anthropometric Parameters in Adolescent Handball Players.

Handball performance is influenced by age, anthropometric characteristics, technical skills, tactical understanding, and physical abilities. The aims of this study were (i) to determine differences in anthropometric characteristics and physical performance between adolescent handball players across age categories, and (ii) to determine which anthropometric and maturity variables have the greatest relative importance in fitness for this sport. Seventy-nine male handball players drawn from a team in the elite Tunisian Handball league [U18 ( = 10); U17 ( = 12); U16 ( = 17); U15 ( = 18); and U14 ( = 22)] volunteered for the investigation.

Effects of a Combined Upper- and Lower-Limb Plyometric Training Program on High-Intensity Actions in Female U14 Handball Players.

Purpose: To analyze the effects of a 9-week plyometric training program on the sprint times (5, 10, 20, and 30 m), change-of-direction speed (modified T test and modified Illinois test), jumping (squat jump, countermovement jump, countermovement jump with arms, and horizontal 5-jump test), upper-body strength (right and left handgrip, back extensor strength, and medicine ball throw), and balance (Y and stork balance tests) of female handball players.

Methods: Athletes were randomly divided into experimental (n = 21; age = 13.5 [0.
