Acute Responses of Youth Elite Players to a Football Match in Terms of Blood Markers.

The current study verified the acute responses of participants to a football match in terms of blood markers. Sixteen elite U-18 male football players were divided into two groups: experimental (EG, n = 10), who played a friendly football match; and control (CG), who were not exposed to any physical exertion. Intravenous blood samples were collected from both groups at baseline, pre-match, half-time, and post-match. The blood analysis consisted of four groups: immunological (leukocytes, platelets, and cortisol), muscle damage (creatine kinase and lactate dehydrogenase), metabolic (lactate, glucose, erythrocytes, hematocrit, hemoglobin, and urea), and electrolytic (sodium, calcium, and potassium). Edwards' training impulse demonstrated that the first half was more demanding than the second half (p = 0.020). Significant changes between time points and groups were observed for leukocytes (pre-match: 6920 ± 1949; post-match: 13,890 ± 3292; p ≤ 0.05) and cortisol (pre-match: 10.78 ± 3.63; post-match: 19.15 ± 7.40; p ≤ 0.05). CK (pre-match: 516.50 ± 248.38; post-match: 713.70 ± 308.20; p ≤ 0.05) and LDH (pre-match: 348.80 ± 36.49; post-match: 414.80 ± 26.55; p ≤ 0.05) increased significantly across the time points for the EG, with no difference between the groups, however. Raised lactate (pre-match: 1.05 ± 0.32; post-match: 3.24 ± 1.60; p ≤ 0.05) and glucose (pre-match: 72.54 ± 9.76; post-match: 101.42 ± 19.87; p ≤ 0.05) differences between the groups at half-time were also observed. These current findings provide helpful information to better understand football match demands regarding physiological effects.

Protocolo de reabilitação acelerada após reconstrução de ligamento cruzado anterior - dados normativos / Accelerated protocol of rehabilitation after anterior cruciate ligament reconstruction with patellar tendon- normative data

OBJETIVO: Avaliar os resultados obtidos com o protocolo de reabilitação acelerada, adaptado às condições de clínica, em pacientes submetidos à operação de reconstrução do ligamento cruzado anterior. MÉTODOS: Foram incluídos 30 pacientes, praticantes de atividade esportiva recreacional, submetidos à operação de reconstrução do ligamento cruzado anterior por meio do tendão patelar. Todos fizeram a reabilitação com o mesmo protocolo de tratamento e no mesmo local. A avaliação isocinética em diferentes ângulos foi realizada antes da operação e no 4° mês de pós-operatório utilizando dinamômetro isocinético computadorizado da marca Cybex Norm. RESULTADOS: As avaliações no pré-operatório em média demonstraram: pico de torque flexor 93 por cento a 60°/s e 97,3 por cento a 180°/s; extensor 87,3 por cento a 60°/s e 94,7 por cento a 180°/s; potência nos músculos flexores de 93,3 por cento e nos extensores de 96,7 por cento; trabalho muscular dos flexores de 91,7 por cento e nos extensores de 90,3 por cento; o ângulo do pico de torque flexor de 28,7°, na musculatura extensora o ângulo foi de 62,2°; pico de torque excêntrico nos flexores de 78,3 por cento e nos extensores de 12,8 por cento. Com quatro meses de pós-operatório os resultados obtidos em média foram: pico de torque flexor 95,4 por cento a 60°/s e 97,1 por cento 180°/s; extensor 70 por cento a 60°/s e 75,7 por cento a 180°/s; potência nos músculos flexores de 97,1 por cento e nos extensores de 79,8 por cento; trabalho muscular dos flexores de 94,2 por cento e nos extensores de 94,2 por cento; pico de torque excêntrico dos flexores de 84 por cento e nos extensores de 24,2 por cento; o ângulo do pico de torque flexor foi a 27,3°; na musculatura extensora o ângulo foi de 61,7°. CONCLUSÃO: Os resultados demonstraram que os pacientes tratados com o protocolo adaptado apresentam resultados semelhantes aos obtidos com o protocolo original em relação às condições musculares.

OBJECTIVE: evaluate the gotten results of the accelerated protocol adapted to the clinic conditions in CLA post operatory patients. METHODS: 30 patients were selected and submitted to an isokynetic test at the pre operatory and 4 months post operatory. RESULTS: the isokinetics evaluations at the pre operatory presented: flexor peak torque 93 percent at 60°/s and 97,3 percent at 180°/s. Extensor 87,3 percent at 60°/s and 94,7 percent at 180°/s; power of the flexor muscles of 93,3 percent and extensors of 96,7 percent; the muscular work of the flexors was of 91,7 percent and extensors of 90,3 percent; the flexor peak torque angle was at 28,7°. At the extensor musculature the angle was at 62,2°; flexors eccentric peak torque of 78,3 percent and the extensors of 12,8 percent. With 4 months of post operatory the gotten results showed: flexor peak torque 95,4 percent at 60°/s and 97,1 percent. at 180°/s; extensor 70 percent at 60°/s and 75,7 percent. at 180°/s; power of the flexor muscles of 97,1 percent and extensors of 79,8 percent; the muscular work of the flexors was of 94,2 percent and extensors of 94,2 percent; flexors eccentric peak torque of 84 percent and extensors of 24,2 percent; the flexor peak torque angle was at 27,3°; in extensor musculature the angle was at 61,7°. CONCLUSION: showed that the patients treated with the adapted protocol presented similar results to the original protocol in relation to the muscular conditions.
