A Combined Balance and Plyometric Training Approach: Effects on Physical Performance Parameters in Youth Male Handball Players: A Randomized Controlled Trial
Abstrct
The physical quality of young male handball players is one of the essential factors that influence team performance. Balance and plyometric training refers to the work of muscle groups related to stabilization located at the meeting of the base of the trunk, spine, pelvis and lower extremities of the human bodyThirty male handball players (age: 16.6±0.5 years) were randomly allocated to either an experi-mental group (n=15) performing combined postural control and plyometric training twice weekly in addition to standard handball training, or a control group (n=15) maintaining regular training alone. Pre- and post-intervention assessments included vertical jump performance (squat jump, countermovement jump), horizontal jump ability (standing long jump), linear sprint speed (5m, 20m), change-of-direction capac-ity (modified T-test, Illinois modified test), repeated change-of-direction ability, and postural control (Stork Balance test, Y-Balance test). The experimental group demonstrated significantly greater improvements compared to controls across multi-ple performance domains. Specifically, superior adaptations were observed in the squat jump (p<0.05), countermovement jump (p<0.01), and standing long jump (p<0.05) performance. Sprint capabilities showed enhanced development in both 5m (p<0.05) performance. Sprint capabilities showed enhanced development in both 5m (p<0.05; d=0.56 [moderate]) and 20m (p<0.05) times. Change-of-direction ability improved sub-stantially in both single-effort (T-half test: p<0.01; Illinois-MT: p<0.01; d=0.85 [large]) and repeated-effort contexts (p=0.05). Dynamic balance measures showed consistent improvements across all planes of movement (p<0.05). Conclusion: Implementing combined postural con-trol and plyometric training twice weekly during the competitive season effectively enhanced multiple aspects of physical performance in youth handball players. The moderate to large effect sizes observed across performance measures suggest this training approach represents an effective strategy for developing athletic capabilities in this population.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
