Aim: The aim of the present study was to investigate the effect of proprioceptive exercises and massage on anaerobic performance and some physical fitness factors of women athletes. Methods: 28 women athletes with an average age of 24.8 ± 2.25 and weight of 60.02 ± 6.26 in four groups; the experimental group (1- massage, 2- proprioception exercises, 3- massage+ proprioception exercises) and the control group were randomly divided. In the pre-test session, all the subjects, with a four-minute warm-up in the form of jogging with an intensity of 30-40% HR, performed tests of anaerobic performance and some physical fitness factors and after a 72-hour washout period, the subjects started their activity for 12 minutes, each in their specialized group and according to the established protocol, and immediately the tests of the pre-test stage were repeated. A dependent t-test and one-way analysis of variance were used to analyze the data. Results: The results showed that the massage + proprioception group had a significant effect on the anaerobic peak power variable by 36.3%. All three groups of massage, proprioception, and massage +proprioception had a significant effect on the variables of average anaerobic power and fatigue index. In the variables of peak anaerobic power (p=0.001), average anaerobic power (p=0.011), fatigue index (p=0.016), and dynamic balance (p=0.015), there is a significant difference between the groups (p>0.05). Conclusion: In anaerobic activities, the use of proprioception exercises along with massage as part of warming up sports activities will most likely improve the performance of athletes.

purpose: One of the new training methods to increase the performance of athletes is ischemic preconditioning (IPC). the aim of the present study was the effect of ischemic preconditioning and beetroot supplementation on anaerobic performance of male cyclists. method: 12 male cyclists participated in a randomized study with a crossover design. The tests of maximum power output and one kilometer cycling time trial were evaluated in the same laboratory conditions. All subjects consumed 60 grams of beetroot supplement and placebo for one week. There was a 7-day washout period between the two supplement and placebo periods.maximum power output and one kilometer time trial tests were performed along with the ischemic preconditioning method. Ischemic preconditioning for all subjects, including 4 periods of 5 minutes of occlusion and reperfusion using a cuff with a width of 15 cm and a pressure of 220 mmHg applied to the uppermost part of the legs. Shapiro-wilk test and repeated measurement were used to check the data. Findings: Ischemic preconditioning significantly increased maximum power compared to control (P=0.027). Although after taking red beet supplement and ischemic preconditioning, the maximum power output was higher than the control condition, but no statistically difference was observed (P=0.09). The time trial of one kilometer after ischemic preconditioning (P=0.014) and also after consumption of beetroot supplement along with ischemic preconditioning was significantly lower than the control condition (P=0.008). Conclusion: ischemic preconditioning and beetroot supplementation can improve anaerobic performance in adult male cyclists

Objective: The aim of the present study was to determine the effect of different doses of acute consumption of beetroot juice on anaerobic performance in trained individuals.Methodology: In a randomized (purposive and accessible) cross-over, double-blind, placebo-controlled experimental design, 9 subjects who were physically active for at least 150 minutes per week and for at least 6 months (age: 20.44±1.33 years, body mass index: 20.55±3.27 kg/m) volunteered to participate in the protocol during 3 weeks in a single session. 2 hours after consuming 70 mL or 140 mL of beetroot juice or 70 mL of placebo, participants completed the anaerobic power test based on running, Sargent jump test, Illinois agility test and the 36-meter speed test with a 10-minute rest interval. Findings: The results of data analysis showed that acute consumption of 70- and 140-ml doses of beet juice had no significant effect on anaerobic power, peak power, average power, minimum power, relative peak power, anaerobic capacity, fatigue index. In addition, acute consumption of 70 and 140 ml of beetroot juice did not have a significant effect on the speed, agility and explosive power of trained people.Conclusion: The results showed that the acute consumption of 70- and 140-ml doses of beet juice does not create any functional advantage for anaerobic power and its components, agility, speed and explosive power in trained people.
