Abstract

Objective: The objective of this study is to analyze the role of mental training in enhancing the psychological readiness of amputee football players to optimize their performance under competitive pressure. Method: The study focuses on three primary techniques of mental training: concentration, relaxation, and mental imagery. These techniques are systematically applied to address psychological challenges faced by amputee football players during competitions, enabling them to manage stress and maintain focus effectively. Results: Findings indicate that structured mental training significantly enhances athletes' ability to handle competitive stress, improving their psychological preparedness. This improvement positively influences their overall performance, complementing their physical, technical, and tactical skills. Novelty: This study highlights the unique psychological challenges faced by amputee football players and emphasizes the necessity of tailored mental training programs. It offers a specialized approach to support athletes with special needs, integrating mental preparation as a core element of their training regimen.

Abstract

Indonesia is one of the largest cassava producing countries in the world with various types and advantages. Waxy clones have a high starch content and therefore they can be used as a food substitute for rice. Tissue culture through somatic embryogenesis is an effective technique for rapid and mass seedling propagation. This research aimed to determine the effect of the type and concentration of auxin 2,4-D or picloram and the addition of NAA on the formation of Waxy cassava clone somatic embryos. This research used a completely randomized design (CRD) which was arranged in a non-factorial. Auxin 2,4-D and picloram were used at four concentration levels: 0 mg.l-1, 8 mg.l-1, 10 mg.l-1, 12 mg.l-1, and additional NAA treatment of 6 mg.l-1 each. Results showed that MS + 6 mg.l-1 NAA treatment produced the highest callus weight. Meanwhile, the percentage of embryonic callus and number of embryo was higher in the treatment of MS + picloram 12 mg.l-1 and NAA 6 mg.l-1 (19,05 ± 5,82 %) and MS + 8 mg.l-1 2,4-D + 6 mg.l-1 NAA (11,11 ± 3,17 %) with 5,48 ± 3,56 and 4,93 ± 1,95 embryos, respectively. Thus, auxin picloram 12 mg.l-1 + NAA 6 mg.l-1 were the most effective in inducing the formation of somatic embryos on waxy cassava clone.
