Ischemic preconditioning (IPC) has been used to increase performance in sports. The aim of this study was to compare the acute effects of IPC with different warm-up methods on the number of repetitions and total volume in resistance exercise (RE). Sixteen healthy men recreationally trained in RE participated in this study. After the anthropometric evaluation and familiarization, a one-repetition maximum (1RM) test and retest were performed in the bench press (BP) and in the leg press 45° (LP) exercise. After these tests, participants were randomly assigned to one of the five protocols: a) IPC; b) SHAM; c) a specific warm-up (SW); d) aerobic exercise (AE), and e) active stretching (AS) prior to performing 3 sets at 80% 1RM until concentric failure. The number of repetitions was higher following IPC compared to the SW following three sets both for the BP and LP. Similarly, the number of repetitions for IPC was higher in comparison to SHAM following three sets for the LP. The number of repetitions was higher following IPC compared to AE following 1st and 2nd sets for the LP and following the 2nd set for the BP. Finally, the number of repetitions was higher following IPC compared to AS following 1st and 2nd sets for the LP. The total volume was higher following IPC compared to SHAM, SW, AE, and AS for both the BP and LP. The IPC protocol increased the number of maximum repetitions and the total volume when compared to the other tested methods, thus indicating a better utilization during the pre-work warm-up. These results indicate positive associative responses to IPC with performance maintenance, which is of importance for both athletes and coaches. [ABSTRACT FROM AUTHOR]

The purpose of this study was to investigate how foam rolling applied to the anterior thigh during the inter-set rest periods affects the repetition performance in the knee extension exercise. Ten recreationally strength trained men were recruited for the study. Initially, the subjects underwent a 1-repetition maximum testing and retesting, respectively. Thereafter, the experiment involved 2 sets of knee extensions with 70% of 1-repetition maximum load to concentric failure with the goal of completing the maximum number of repetitions. During the inter-set rest period, either passive rest (PR) or 60 sec of passive foam rolling (FR60) in a randomized order was applied. Given that the number of repetitions with PR was not statistically different from FR60 (P=0.14001), the findings suggest that inter-set foam rolling of the agonist muscle group did not influence maximum repetition performance and has important implications for foam rolling prescription when used in both rehabilitation and athletic populations. If the purpose is to improve repetition performance and training volume, foam rolling should not be applied to the agonist muscle group between sets or before knee extensions exercises.

Currently, chronic degenerative such as systematic arterial hypertension (SAH) has represented a global public health problem. In this context, SAH diagnosed when blood pressure levels remain chronically elevated above the cut categorizations attributed to normality, represents an increased risk regarding events and cardiac involvement. Individuals who have access to higher education have, hypothetically, privileged socioeconomic and cultural levels are expected to have satisfactory living habits categorized as satisfactory and it is believed that such habits contribute to a prophylactic and treatment effect concerning blood pressure levels. Thus, the purpose of the present study was to identify the prevalence of systemic arterial hypertension in Physical Education undergraduate students at Rio de Janeiro Public University. To this end, the sample size was calculated and 290 subjects participated in the study. Each subject had their blood pressure measured twice by the oscillometric method with a minimum interval of 10-minutes among the measurements. The descriptive statistics indicates a prevalence of 12.4% of systemic arterial hypertension in this population. This value may not be neglected in view of the young and possible active character of this population. [ABSTRACT FROM AUTHOR]

Background: The Functional Movement Screen (FMS™) is a battery of tests designed to assess movement competency; the overhead deep squat test, specifically, has been shown to be an accurate predictor of overall FMS™ scores. Self-massage (SM) is a ubiquitous warm-up utilized to increase joint range of motion and, therefore, may be effective for improving performance of the overhead deep squat test. Purpose: To examine how different doses (30, 60, 90, and 120 seconds) of SM of different areas of the body (plantar fascia, latissimus dorsi, and lateral thigh) affects the score obtained on an overhead deep squat test. Methods: Twenty recreationally active females were recruited to be tested on four occasions: sessions one and two consisted of baseline testing, session three consisted of SM applied to the lateral thigh, and session four consisted of SM applied to the lateral torso and plantar fascia. Results: In all SM conditions, at least 90 seconds was required for a change in deep squat score from baseline; therefore, it is concluded that SM the lateral torso, plantar fascia, and lateral thigh for 90 seconds or more are effective interventions for acutely improving overhead deep squat scores. Conclusion: Self-massage appears to be an effective modality for inducing acute improvements in the performance of the FMS™ overhead deep squat in all conditions tested. Level of evidence: 2b [ABSTRACT FROM AUTHOR]

Background: Foam rollers, or other similar devices, are a method for acutely increasing range of motion, but in contrast to static stretching, do not appear to have detrimental effects on neuromuscular performance. Purpose: The purpose of this study was to investigate the effects of different volumes (60 and 120 seconds) of foam rolling of the hamstrings during the inter-set rest period on repetition performance of the knee extension exercise. Methods: Twenty-five recreationally active females were recruited for the study (27.8 ± 3.6 years, 168.4 ± 7.2 cm, 69.1 ± 10.2 kg, 27.2 ± 2.1 m²/kg). Initially, subjects underwent a ten-repetition maximum testing and retesting, respectively. Thereafter, the experiment involved three sets of knee extensions with a predetermined 10 RM load to concentric failure with the goal of completing the maximum number of repetitions. During the inter-set rest period, either passive rest or foam rolling of different durations (60 and 120 seconds) in a randomized order was employed. Results: Ninety-five percent confidence intervals revealed dose-dependent, detrimental effects, with more time spent foam rolling resulting in fewer repetitions (Cohen's d of 2.0 and 1.2 for 120 and 60 seconds, respectively, in comparison with passive rest). Conclusion: The results of the present study suggest that more inter-set foam rolling applied to the antagonist muscle group is detrimental to the ability to continually produce force. The finding that inter-set foam rolling of the antagonist muscle group decreases maximum repetition performance has implications for foam rolling prescription and implementation, in both rehabilitation and athletic populations. Level of evidence: 2b [ABSTRACT FROM AUTHOR]

Background: Foam rolling (FR) is a common intervention utilized for the purpose of acutely increasing range-of-motion without subsequent decreases in performance. FR is characterized as an active technique which subject performs upon themselves. Thus, it is believed that the accumulated fatigue can influence whether the task can be continued. Purpose: To analyze the effect of different foam rolling volumes on fatigue of the knee extensors. Methods: Twenty-five recreationally active females (age 27.7 ± 3.56 y, height 168.4 ± 7.1 cm, weight 69.1 ± 10.2 kg) were recruited for the study. The experiment involved three sets of knee extensions with a pre-determined 10 repetition maximum load to concentric failure. Then, subjects performed the control (CONT) and foam rolling (FR) conditions. FR conditions consisted of different anterior thigh rolling volumes (60-, 90-, and 120-seconds) which were performed during the inter-set rest period. After that, the fatigue index was calculated and compared between each experimental condition. Fatigue index indicates how much (%) resistance the subjects experienced, calculated by the equation: (thidset/firstset) x 100. Results: Fatigue index was statistically significantly greater (greater fatigue resistance) for CONT compared to FR90 (p = 0.001) and FR120 (p = 0.001). Similarly, higher fatigue resistance was observed for FR60 when compared to FR120 (p = 0.048). There were no significant differences between the other conditions (p > 0.005). Conclusion: The finding of foam rolling fatigue index decline (less fatigue resistance) as compared to control conditions may have implications for foam rolling prescription and implementation, in both rehabilitation and athletic populations. For the purposes of maximum repetition performance, foam rolling should not be applied to the agonist muscle group between sets of knee extensions. Moreover, it seems that volumes greater than 90-seconds are detrimental to the ability to continually produce force. Level of evidence: 2b [ABSTRACT FROM AUTHOR]
