Acute effects of different intervals between repeated sprints on performance responses in amateur futsal athletes / Efeitos agudos de diferentes intervalos entre sprint repetidos sobre as respostas de desempenho em atletas amadores de futsal

ABSTRACT Objective: Verify the influence of different break times between sprints on the performance of amateur futsal athletes. Methods: 10 individuals, men, amateur futsal athletes (Age: 21.5 ± 1.6; Weight: 72.4 ± 6.88; Height: 1.72 ± 0.05; BMI: 24.3 ± 1.2; Fat%: 13.7 ± 3.3, VO2peak: 49.1 ± 10.5) participated in the study. Individuals were randomly selected to perform sessions with sprints (10 sets 20 m) with different pause times of 15 (S15), 30 (S30) and 60 (S60) seconds. For performance analysis, the speed (km / h) applied to each sprint was used and monitored by a device with a photocell (CEFISE Biotecnologia Esportiva®). Results: There was an interaction between speed and interval time (p = 0.000). For condition S15, a greater reduction in performance was observed (p ≤ 0.05), while for S30 and S60, no significant reduction in performance was observed (p > 0.05). The data for the area under the curve showed a significant difference (p = 0.000), where the interval of 60 s (S60) was longer compared to the values of 30 (S30) (p = 0.000) and 15 s (S15) (p = 0.000). However, there were no significant differences between the 30 and 15 s data (p = 0.248). Conclusion: A shorter time (15 s) interval between repeated sprints can significantly affect performance compared to longer breaks (30 and 60 s), but all the conditions tested here can be positive for the improvement of performance, mainly in sports that demand fast and efficient motor actions such as futsal.

RESUMO Objetivo: Verificar a influência dos diferentes tempos de intervalo entre os sprints no desempenho dos atletas de futsal amadores. Métodos: 10 indivíduos, homens, atletas de futsal amadores (Idade: 21,5 ± 1,6; Peso: 72,4 ± 6,88; Altura: 1,72 ± 0,05; IMC: 24,3 ± 1,2; Gordura%: 13,7 ± 3,3, VO2peak: 49,1 ± 10,5) participou no estudo. Os indivíduos foram selecionados aleatoriamente para realizar sessões com sprints (10 conjuntos 20 m) com diferentes tempos de pausa de 15 (S15), 30 (S30) e 60 (S60) segundos. Para análise do desempenho, a velocidade (km/h) aplicada a cada sprint foi utilizada e monitorizada por um dispositivo com uma fotocélula (CEFISE Biotecnologia Esportiva®). Resultados: Houve uma interação entre velocidade e tempo de intervalo (p = 0,000). Para a condição S15, observou-se uma maior redução no desempenho (p ≤ 0,05), enquanto para S30 e S60, não se observou qualquer redução significativa no desempenho (p > 0,05). Os dados para a área sob a curva mostraram uma diferença significativa (p = 0,000), onde o intervalo de 60 s (S60) foi mais longo em comparação com os valores de 30 (S30) (p = 0,000) e 15 s (S15) (p = 0,000). No entanto, não houve diferenças significativas entre os dados de 30 e 15 s (p = 0,248). Conclusão: Um intervalo de tempo mais curto (15 s) entre sprints repetidos pode afetar significativamente o desempenho em comparação com os intervalos mais longos (30 e 60 s), mas todas as condições aqui testadas podem ser positivas para a melhoria do desempenho, principalmente nos desportos que exigem ações motoras rápidas e eficientes, tais como o futsal.

Higher Muscle Damage Triggered by Shorter Inter-Set Rest Periods in Volume-Equated Resistance Exercise.

Objectives: The aim of the manuscript was to analyze the effects of two rest periods between volume-equated resistance exercise (RE) on inflammatory responses (cytokines and leukocyte) and muscle damage. Methods: Ten trained men (26.40 ± 4.73 years, 80.71 ± 8.95 kg, and 176.03 ± 6.11 cm) voluntarily participated in training sessions consisting of five sets of 10 reps performed at 10-RM on (1) the barbell bench press followed by (2) leg press, with either 1- or 3-min rest between sets and exercises. Circulating concentrations of different biomarkers was measured before (Pre), and after 3 h (excepted for cytokines), 6, 12, and 24 h from exercise. The rate of perceived exertion (RPE) was recorded after each set on both planned visits. Results: We found greater increases triggered by the 1-min rest period in Creatine Kinase (CK), occurring from 12 to 24 h post-exercise compared to the 3-min rest condition. A significant increase in the 1-min rest condition was also observed in the total number of leukocytes, neutrophils, and monocytes. The 1-min rest period also triggered increases compared to baseline in pro-inflammatory cytokines [Interleukin 1 beta (IL-1ß), p = 0.004; tumor necrosis factor α (TNF-α), p = 0.01; and granulocyte-macrophage colony-stimulating factor (GM-CSF), p = 0.01], which were more evident after 6 and 12 h post-exercise. Similarly, increases in anti-inflammatory cytokines [Interleukin 5 (IL-5), p = 0.01; Interleukin 6 (IL-6), p = 0.01; and Interleukin 10 (IL-10), p = 0.01] at all time-points were observed. Conclusion: Our results indicate that a 1-min rest condition in volume-equated RE promoted greater overall muscle tissue damage with a longer duration of the inflammatory processes compared to a 3-min rest.

Sodium bicarbonate supplementation in resistance exercise performance, perceived exertion and blood lactate concentration

Aim: The aim was to evaluate the effect of sodium bicarbonate supplementation (NaHCO3) in repetition performance, perceived exertion and blood lactate concentration. Methods: Fourteen trained men (25.14 ± 3.5 years; 85.83 ± 10.18 kg; 1.78 ± 0.06 m; 26.88 ± 3.17 kg/m2) realized two upper-body resistance exercise sessions consisting of 15-RM load and 1 minute of the interval, combining bicarbonate supplementation (BS) or Placebo conditions. Results: After the ANOVA analysis, no difference was found on the total number of repetitions during the session on both BS and Placebo condition (p = 0.11). However, a greater number of total of repetitions on the machine chest fly exercise for BS vs. Placebo condition (p = 0.04) was observed. The perceived exertion increased regardless of the supplementation condition (p < 0.0001). Additionally, for the blood lactate was observed significant increases in BS vs. Placebo condition in the post verification (p = 0.013), corroborated for a bigger area under the curve (AUC) on the BS compared to Placebo (p = 0.026) condition. Conclusion: In conclusion, sodium bicarbonate supplementation was not able to improve performance during a resistance exercise session, except for the single-joint exercise performed with high values of perceived exertion, not altering the perceived exertion, and blood lactate between protocols.(AU)

Cardiovascular and strength adaptations in concurrent training in hypertensive women / Adaptações cardiovasculares e de força no treinamento concorrente em mulheres hipertensas / Adaptaciones cardiovasculares y de fuerza en el entrenamiento concurrente en mujeres hipertensas

ABSTRACT Introduction Physical exercise has been recommended as a non-pharmacological strategy for preventing and controlling hypertension. Objective To verify chronic cardiovascular and muscle strength adaptations in hypertensive women who underwent 12 weeks of concurrent training (CT) in different orders. Methods Twenty hypertensive women were randomly assigned into 2 groups: resistance exercise-endurance group (REE; 56.00 ± 5.20 years; 78.95 ± 8.28 kg; 155.10 ± 5.30 cm; 33.00 ± 5.30 kg.m-2) and endurance-resistance exercise group (ERE; 57.10 ± 13.38 years; 76.56 ± 18.87 kg; 155.50 ± 8.18 cm; 31.41 ± 5.84 kg.m-2). The endurance exercise was composed of 3 sets of 4 exercises, with 8-RM loads with a 90-second break between sets and exercises. The resistance exercise lasted for 25 minutes and was of progressive intensity. Muscle strength (8-RM), systolic and diastolic blood pressure, heart rate, and double product were assessed pre- and post-exercise. Results The ANOVA showed significant increases in strength for all exercises (p <0.0001) regardless of the order of the concurrent training (bench press, p = 0.680; leg press, p = 0.244; seated row, p = 0.668; and leg extension, p = 0.257). No significant differences in systolic (p = 0.074) and diastolic blood pressures (p = 0.064) were observed for different CT conditions. However, significant reductions in systolic (p = 0.0001) and diastolic blood pressures (p = 0.006) and double product (p = 0.006) only occurred in the REE group. Conclusion Endurance training and resistance exercise promote significant muscle strength gains after 12 weeks of training regardless of CT order in hypertensive women. Beneficial cardiovascular responses (SBP, DBP, and RPP) were also observed when endurance training was initiated. Level of evidence I; Therapeutic Studies - Investigating Treatment Outcomes.

Multi- To Single-Joint or the Reverse Exercise Order Does Not Affect Pectoralis Major Workout Performance.

The purpose of this study was to examine the acute effects of multi- to single-joint or the reverse exercise order on repetition performance and perceived exertion for the pectoralis major. Fourteen trained men (24.05 ± 4.17 yrs, 78.85 ± 3.51 kg, 175.42 ± 4.01 cm) underwent two different training sequences (SEQ1 and SEQ2). In SEQ1, all subjects performed 5 sets for maximal repetitions, with a 2-min rest interval, of the bench press followed by the machine chest fly with 10 repetitions maximum load. In SEQ2, the same procedures were repeated, but with the reverse order. The t-test did not show any differences (p = 0.140) in total workout repetitions between SEQ1 (62.22 ± 11.00 repetitions) and SEQ2 (55.40 ± 8.51 repetitions). Conversely, the total repetition number for the bench press exercise was significantly greater (p = 0.001) following SEQ1 (34.36 ± 4.68 repetitions) compared to SEQ2 (25.85 ± 6.73 repetitions). In contrast, the total repetition number for the machine chest fly exercise following SEQ2 was significantly greater (p = 0.001) (33.50 + 4.11 repetitions) compared to SEQ1 (27.85 ± 6.52 repetitions). Despite no significant differences found for the rating of perceived exertion (RPE) values between SEQ1 and SEQ2 for the barbell bench press in all sets (p ≥ 0.083), significantly higher RPE values for the machine chest fly were observed over the first three sets following SEQ1 compared to SEQ2 (p < 0.01). In conclusion, the total workout repetitions were not significantly different when performing the traditional multi- to single-joint or the reverse exercise order when training the pectoralis major muscle.

Heavy vs Light Load Single-Joint Exercise Performance with Different Rest Intervals.

The aim of the study was to compare the effect of three distinct rest period lengths between sets of upper body single-joint exercise with different load zones and volume designed for either endurance or hypertrophy (50% or 80% of 1-RM). Sixteen trained men (20.75 ± 2.54 years; 76.35 ± 5.03 kg; 176.75 ± 3.33 cm, 24.53 ± 1.47 kg/m2) performed a test and retest of 1-RM on non-consecutive days. Forty-eight hours after load testing, the participants were randomly assigned to six sessions consisting of four sets of the triceps pull-down, combining different intensities with distinct rest periods between sets. The shorter 1 minute rest promoted a significant reduction in the total repetition number compared to 3 minute rest for both workloads. There was a difference between 3 and 5 minute conditions for the 50% of 1-RM that did not occur for the 80% of 1-RM condition. Both intensities presented significant interaction values for the rest conditions vs. each set (50% p = 0.0001; 80% p = 0.0001). Additionally, significant values were found for the main effect of the performance of subsequent sets (50% p = 0.003; 80% p = 0.001) and rest conditions (50% p = 0.0001; 80% p = 0.0001). In conclusion, for heavier loads (80%) to fatigue, longer rest of 3 to 5 minutes seems to allow for better recovery between sets and thus, promotes a greater volume. However, when training with lighter loads (50%), the magnitude of the rest seems to directly affect the performance of subsequent sets, and also presents a correlation with total volume achieved for the upper body single-joint exercise scheme.

Pressão arterial de mulheres praticantes de ginástica funcional / Blood presure in women core training practitioners / Blood presure in women core training practitioners

O objetivo deste estudo foi avaliar os efeitos de uma sessão de treinamento funcional tradicional sobre a pressão arterial de mulheres adultas. Foram estudadas 24 mulheres sem experiência no treinamento funcional (25 ± 5 anos; 53 ± 6 kg; 164 ± 5 cm; IMC = 23,09 ± 2,64; 22,99 ± 3,38 % de Gordura). Todas realizaram uma aula de treinamento funcional com bola (GTF) e participaram de uma sequência de controle (SC). Foram observadas a pressão arterial sistólica (PAS) e diastólica (PAD) nas seguintes situações: antes, logo após, 10, 20, 30, 40, 50 e 60 minutos após o treinamento. A ANOVA (análise de variância) não mostrou diferenças significativas na PAS entre as seqüências realizadas, contudo, observou-se uma redução significativa (p<0,05) a partir do vigésimo minuto em relação ao repouso (Δ% = 8,00%, p = 0,001). Essa diminuição perdurou até e inclusive a última aferição da PAS (Δ% = 6,87%, p = 0,02). Na PAD os resultados foram significativamente menores a partir do décimo minuto em relação ao repouso (Δ% = 5,80%, p = 0,0002), e se mantiveram até a ultima verificação (Δ% = 5,87%, p = 0,0001). Em relação ao momento logo após o exercício a PAD apenas alterou-se significativamente no trigésimo (Δ% = 5,85%, p = 0,0004) e quinquagésimo minuto (Δ% = 4,14%, p = 0,006), mostrou-se reduzida. O treinamento funcional com bola promoveu uma diminuição nos níveis de PAS e PAD em mulheres normotensas

Efeito da ginástica funcional sobre a pressão arterial, frequência cardíaca e duplo produto em mulheres / Acute effects of functional gymnastic training on blood pressure, heart beat rate and heart beat-pressure product in females

Objetivo do estudo foi verificar efeitos do treinamento funcional sobre a pressão arterial sistólica (PAS) e diastólica (PAD), freqüência cardíaca (FC) e duplo produto (DP) de 24 mulheres inexperientes (25 ± 5 anos; 53 ± 6 kg; 164 ± 5 cm; IMC = 23,09 ± 2,64; 22,99 ± 3,38% de Gordura). Realizou-se uma aula de treinamento funcional e uma seqüência controle. As variáveis foram observadas antes, logo após, 10, 20, 30, 40, 50 e 60 minutos após o treinamento. A ANOVA observou diminuições significativas na PAS, a partir do vigésimo minuto ( % = 8,00%, p = 0,001) e na PAD, iniciando no décimo minuto ( % = 5,80%, p = 0,0002) em relação ao repouso. No momento logo após, a PAD obteve redução no trigésimo ( % = 5,85%, p = 0,0004) e qüinquagésimo minuto ( % = 4,14%, p = 0,006). Ocorreu um aumento na FC logo após a sessão (∆% = 40,02%, p = 0,0001) e reduções a partir de 40 minutos após (∆% = 7,95%, p = 0,01). O DP reduziu a partir de 20 minutos após o exercício (∆% = 13,5%, p = 0,0002). O treinamento funcional reduziu significantemente a PAS, PAD, FC e DP após um treinamento em mulheres jovens.

The effects of functional training sessions on systolic (SBP) and diastolic (DBP) blood pressure, heart beat rate (HR) and heart beat-pressure product (HPP) in 24 untrained women (25 ± 5 years; 53 ± 6 kg; 164 ± 5 cm; 23.09 ± 2.64 kg m-2; 22.99 ± 3.38% body fat) were investigated. The subjects participated on a functional training class following by a control follow-up. Variables were registered prior to training exercise, and 10, 20, 30, 40, 50 and 60 minutes after training. Whereas ANOVA reported a significant decrease (p < 0.05) in SBP as from the twentieth minute ( % = 8.00%, p = 0.001), decrease in DBP started at the tenth minute ( % = 5.80%, p = 0.0002). Significant decreases were observed at the thirtieth ( % = 5.85%, p = 0.0004) and fiftieth ( % = 4.14%, p = 0.006) minute. HR increase was reported immediately after the test ( % = 40.02%, p = 0.00) and presented significant decreases as from the fourth minute ( % = 7.95%, p = 0.01). Decreases in HPP rates were observed at twenty minutes after the exercise ( % = 13.5%, p = 0.0002). Data analysis show that functional training sessions triggered significant reductions on SBP, DBP, HR and HPP in young females.

Hypotensive effects of resistance exercises performed at different intensities and same work volumes

The aim of this paper was to compare the effects of two sequences of resistance exercises (RE), with different intensities but same training volume, on post-exercise blood pressure responses. Sixteen young subjects with previous experience in RE were evaluated during three non-following days in chest press, legpress, pulley pull down, leg curl, shoulder press, and biceps curl. On the first day, the load associated with six maximal repetitions (6RM) were determined for each exercise. On the second day, three sets of 6RM were performed (SEQ6), with a two minute interval between the sets. On the last day, the same procedure was repeated, but using 12 repetitions with 50 percent of 6RM load (SEQ12). Rest BP was measured before the sequences by auscultatory method. Post-exercise resting BP was measured each 10 minutes by ambulatory BP monitoring during 60 minutes. The magnitude and duration of BP variability were compared by repeated ANOVA measures followed by Tuckey post-hoc test (p < 0.05). A significant reduction in diastolic blood pressure (DBP) was observed in the first 20 minutes after SEQ12, but not after SEQ6. SEQ12 elicited significant decline in systolic blood pressure (SBP), at least during the first 50 minutes after the exercise, while significant reductions were observed in all measures after SEQ6. There were no significant differences between the absolute values of DBP and SBP after both sequences. In conclusion: a) RE had hypotensive effects on blood pressure, mainly SBP; b) the absolute decline of SBP seem not to be influenced by different interactions between workload and number of repetitions; c) higher workloads seem to extend the total time of SBP post-exercise reduction; d) the number of repetitions seems to have more influence on DBP than SBP, but for a short period of time
