Thirty untrained women were randomly and proportionally divided into three groups: HI = high-intensity exercises (80% of one-repetition maximum (1RM)); LL = low-load exercises (20% of 1RM); and LL+BFR = LL exercises combined with BFR. The exercise sessions were performed during the 3rd-4th days (follicular phase), 16th day (ovulatory phase) and the 24th-26th days (luteal phase) of the MC. Before and immediately after the exercises, SBP, DBP, HR and SpO2 were evaluated. We observed an increase in SBP, HR and DP in the three phases of the MC for all groups (p < 0.05). Groups LL and/or LL+BFR exhibited a greater increase in SBP, DBP, MBP, HR and DP when co...

Twenty-five men with experience in ST were randomly divided into 3 experimental groups: a) 4 low-load exercises at 20% of the one-repetition maximum (1RM) combined with continuous BFR (LL+CBFR), b) 4 low-load exercises at 20% of 1RM combined with intermittent BFR (LL+IBFR); and c) 4 low-load exercises at 20% of 1RM without BFR (LL). Twelve sessions of ST were performed (twice a week for 6 weeks). There were no differences between groups for all variables (p > 0.05). However, there were significant differences in time for the LME in the triceps pulley only in the LL+CBFR group (p < 0.001) and in the biceps pulley in the groups LL+CBFR, LL+IBFR and LL (p < 0.001, p = 0.002, p = 0.032), respectively, with large magnitudes only for the two forms of the BFR. It can be concluded that continuous or intermittent BFR seems to be a good alternative for the increase of the LME of the upper limbs in single-joint exercises.

Participaram do estudo 13 universitários normotensos (19.5 ± 1.7anos). Os participantes foram divididos randomicamente em duas sessões experimentais (cross-over): a) exercício aeróbico com a RFS (EARFS); b) exercício aeróbico sem a RFS (EASRFS). As sessões foram realizadas com cinco séries de dois minutos e um minuto de intervalo. A PAS, PAD e FC foram mensurados em repouso, no final dos exercícios e durante os 60 minutos pós-exercício. O EASRFS apresentou efeito hipotensivo no 60º pós-exercício (p= 0.029); o EA com e sem RFS elevou significativamente a PAS e FC imediatamente após o exercício (p< 0.05), e o EARFS apresentou valores de PAD e FC superiores, no momento imediatamente pós-exercício, quando comparado com o EASRFS (p= 0.001; p< 0.001, respectivamente). Conclui-se, que o EARFS parece não maximizar o efeito hipotensivo, ambos as sessões podem elevar a PAS e FC imediatamente pós-exercício com valores significativos maiores na PAD e FC para o EARFS.

After a one-repetition maximum test, 10 normotensive recreationally trained men performed three experimental protocols. In the three RE protocols, increases in SBP, DBP, and MAP were observed immediately after exercise, but the effect sizes (ESs) were greater for the LI + CBFR and high-intensity protocols. There were hypotensive effects on SBP, DBP, and MAP in all three protocols; however, the effects on MAP lasted longer for the LI + IBFR and LI + CBFR protocols. These long-lasting hypotensive effects on DBP and MAP occurred in all three protocols. Thus, we conclude that the post exercise hypotensive effects on SBP, DBP, and MAP appear to occur in all three RE protocols, with the effect on SBP being longer in the LI + IBFR and LI + CBFR protocols.

A amostra foi constituída por 300 mulheres brasileiras com idades compreendidas entre 20 e 83 anos (48.96 ± 15.41), divididas em quatro grupos: Grupo 1 = 75 mulheres adultas não praticantes com idades entre 20 e 49 anos; Grupo 2 = 75 mulheres de meia-idade e idosas não praticantes com idades entre 50 e 82 anos; Grupo 3 = 75 mulheres de meia-idade e idosas praticantes com idade entre 50 e 83 anos e Grupo 4 = 75 mulheres adultas praticantes com idade entre 20 e 49 anos. O instrumento utilizado para determinar à imagem corporal actual e desejada foi a Escala de Desenhos de Silhuetas descrita por Stunkard. Os resultados demonstram que não houve diferenças significativas com a insatisfação da imagem corporal entre os grupos de mulheres adultas vs. meia-idade e idosas vs. praticantes vs. não praticantes (p>0.05). Entretanto, houve diferenças significativas entre a insatisfação com a imagem corporal actual vs. ideal para todos os grupos do estudo (p<0.05). Conclui-se que a idade e a prática da hidroginástica não são factores determinantes na percepção que as mulheres têm da imagem corporal.

Objective: To investigate whether a change in the type of platform in different intensities (60 and 80% 1MR) in bench press exercise can affect the strength performance and the subjective effort perception (SEP) of trained men. Methods: Twenty-six apparently healthy men (23.2 ± 3.7 years, 1.77 ± 0.07 m, 79.6 ± 12.3 kg, 25.4 ± 2.9 kg/m 2) performed the test and retest of 1RM of a bench press (BP) on a stable platform (SP). The subjects were randomly divided into four experimental situations, in which all of them performed the BP tests at 60% and 80% of 1RM on the UP and 60% and 80% of 1MR on the SP. Results: The strength performance (the number of repetitions and total volume) of the BP exercise was significantly higher on a SP compared to an UP (P < 0.001) for both intensities. The SEP was significantly higher on the UP compared to the SP (P < 0.001) and at an intensity of 80% of 1RM compared to 60% of 1RM (P < 0.001). Conclusion: Acutely, regardless of the intensity, the BP exercise promotes better strength performance when performed on a SP and provides a greater effort sensation when performed on the UP.

A amostra não probabilística foi constituída de 30 indivíduos divididos em dois grupos: grupo alongamento estático (GA= 15) e grupo sem alongamento (GC= 15). Para avaliação da força muscular através do teste de 1RM foi utilizado um dinamómetro modelo 32527pp400 Pound push/pull acoplado nos aparelhos cadeira extensora (CE) e supino reto/horizontal (SH). Utilizou-se o teste de Wilcoxon para as comparações intragrupos e o teste de Kruskal-Walis para as comparações intergrupos (p< 0.05). Não foram observadas diferenças estatisticamente significativas (p> 0.05) entre o GA e o GC para o exercício CE e SH. Pode-se concluir que não houve redução no desempenho do teste de 1RM para os exercícios CE e SH, quando precedidos por alongamento estático.

A soft tissue metastasis is extremely rare, and synchronous metastases to the bone and soft tissue is not reported in the literature so far. We report such a case of a 42-yr-old male, who presented with a goiter, scalp and forearm soft tissue swellings, and, fine needle aspiration cytology of all these swellings revealed a follicular neoplasm. A wide excision of the forearm swelling was carried out and the histopathology was consistent with features of metastatic follicular carcinoma of the thyroid. The main stay of treatment is surgical resection of the primary tumor. The various modalities of treatment of metastasis is discussed with a review of literature.

After a one-repetition maximum test, 10 normotensive recreationally trained men performed three experimental protocols. In the three RE protocols, increases in SBP, DBP, and MAP were observed immediately after exercise, but the effect sizes (ESs) were greater for the LI + CBFR and high-intensity protocols. There were hypotensive effects on SBP, DBP, and MAP in all three protocols; however, the effects on MAP lasted longer for the LI + IBFR and LI + CBFR protocols. These long-lasting hypotensive effects on DBP and MAP occurred in all three protocols. Thus, we conclude that the post exercise hypotensive effects on SBP, DBP, and MAP appear to occur in all three RE protocols, with the effect on SBP being longer in the LI + IBFR and LI + CBFR protocols.

Os resultados demonstram que não houve diferenças significativas com a insatisfação da imagem corporal entre os grupos de mulheres adultas vs. meia-idade e idosas vs. praticantes vs. não praticantes (p>0.05). Entretanto, houve diferenças significativas entre a insatisfação com a imagem corporal actual vs. ideal para todos os grupos do estudo (p<0.05). Conclui-se que a idade e a prática da hidroginástica não são factores determinantes na percepção que as mulheres têm da imagem corporal.

Objective: To investigate whether a change in the type of platform in different intensities (60 and 80% 1MR) in bench press exercise can affect the strength performance and the subjective effort perception (SEP) of trained men. Methods: Twenty-six apparently healthy men (23.2 ± 3.7 years, 1.77 ± 0.07 m, 79.6 ± 12.3 kg, 25.4 ± 2.9 kg/m 2) performed the test and retest of 1RM of a bench press (BP) on a stable platform (SP). The subjects were randomly divided into four experimental situations, in which all of them performed the BP tests at 60% and 80% of 1RM on the UP and 60% and 80% of 1MR on the SP. Results: The strength performance (the number of repetitions and total volume) of the BP exercise was significantly higher on a SP compared to an UP (P < 0.001) for both intensities. The SEP was significantly higher on the UP compared to the SP (P < 0.001) and at an intensity of 80% of 1RM compared to 60% of 1RM (P < 0.001). Conclusion: Acutely, regardless of the intensity, the BP exercise promotes better strength performance when performed on a SP and provides a greater effort sensation when performed on the UP.

A amostra não probabilística foi constituída de 30 indivíduos divididos em dois grupos: grupo alongamento estático (GA= 15) e grupo sem alongamento (GC= 15). Para avaliação da força muscular através do teste de 1RM foi utilizado um dinamómetro modelo 32527pp400 Pound push/pull acoplado nos aparelhos cadeira extensora (CE) e supino reto/horizontal (SH). Utilizou-se o teste de Wilcoxon para as comparações intragrupos e o teste de Kruskal-Walis para as comparações intergrupos (p< 0.05). Não foram observadas diferenças estatisticamente significativas (p> 0.05) entre o GA e o GC para o exercício CE e SH. Pode-se concluir que não houve redução no desempenho do teste de 1RM para os exercícios CE e SH, quando precedidos por alongamento estático.

Research paper thumbnail of Synchronous Bony and Soft Tissue Metastases from Follicular Carcinoma of the Thyroid

Journal of Korean Medical Science, 2003

A soft tissue metastasis is extremely rare, and synchronous metastases to the bone and soft tissue is not reported in the literature so far. We report such a case of a 42-yr-old male, who presented with a goiter, scalp and forearm soft tissue swellings, and, fine needle aspiration cytology of all these swellings revealed a follicular neoplasm. A wide excision of the forearm swelling was carried out and the histopathology was consistent with features of metastatic follicular carcinoma of the thyroid. The main stay of treatment is surgical resection of the primary tumor. The various modalities of treatment of metastasis is discussed with a review of literature.
