Abstract
One of the most important success factors in most athletic competitions, receiving aerobic power (speed,
agility and jumping) high. Basketball is a great combination of short and long term activities that depend on
aerobic fitness. Anaerobic fitness of many players during the match determines tactical the performance.
The purpose of the present study to investigate the effects of strength exercises on anaerobic power and
some the variables related Traband it. The subjects consisted of 30 basketball players Young, randomly into
two equal groups of 15 subjects (experimental and control) were randomly assigned to 6 weeks and 3
sessions the Exercises were done in a week. To analyze the data, independent samples T-test and paired
sample T-test used at a significance level p ≤ 0/05. Later for six weeks of exercises, significant differences
between the records obtained from the anaerobic power the variables (speed, agility, vertical jump) were
observed between the two groups. The present study showed that the strength exercises with the variables
Traband improve anaerobic power in young basketball players and And according to the results of seem to
exercises Traband useful method for improving performance of the anaerobic the athletes.

Abstract
Proprioception is essential for joint function and through which individual can detect body parts movement in space. Aim of present study is to investigate effect of balance training on unstable platform with tilting, translation and combined motion on knee joint position sense in active young males. 39 healthy active male divided in to three training and control (n=9) groups. Training on unstable platform with tilting motion group (n=10), Training on unstable platform with translating motion group (n=10) and combined training group (n=10) performed exercises program for 8 weeks, three times a week. Errors in repositioning of knee joint in 30, 45 and 60⁰ angles (active and passive) was measured by Biodex system 3, before and after training period. Data was analysed by using one-way ANOVA test (P≤0/05). Although after 8 weeks, active and passive errors in repositioning of knee joint in mentioned angles decreased in training groups but this difference was not significant (P≤0/05). Balance training on unstable platform alone cannot have a big effect on knee joint position sense in active young male.

Abstract
The purpose of this study was to compare the prevalence of injuries in the Iranian Football Premier League players before and after the outbreak of Coronavirus (COVID-19) through video analysis in the 2019-2020 season. The types of sports injuries were divided into acute and chronic categories based on the mechanism, and the injuries were analyzed by reviewing 143 videos from 239 matches. Prevalence, time of onset and affected area were recorded in a special sheet. According to the results, 219 injuries occurred before the outbreak of coronavirus and 276 injuries occurred after the outbreak of coronavirus. In the period before and after the outbreak of Corona virus, the lower limbs of the players (58/7%) were damaged more than other parts of their bodies. Also, the highest rate of injury occurred after the outbreak of coronavirus than before in the last minutes of the game (24/3%). Research Findings showed that the prevalence of injuries in Iranian Premier League football players in the post-outbreak period of Coronavirus increased due to home quarantine and closure of matches.

Abstract
Circadian rhythms play a crucial role in regulating various physiological functions of the human body and can impact the ability tasks. The aim of this study was to investigate the effect of time of day on static and dynamic balance using the cognitive task approach. We recruited 24 elderly men who performed both static and dynamic balance tests with and without cognitive dual tasks. Our statistical analysis, using a significance level of 0.05, revealed significant differences in the parameters of the 95% confidence ellipse, length of path, and average velocity of the center of pressure when performing the dual task compared to normal walking. However, these variables did not significantly differ at different times of the day. Interestingly, our results showed that the center of pressure fluctuations in closed eyes and different times of the day did not have a significant difference. Overall, our findings suggest that healthy elderly individuals are at similar risk of falling during different hours of the day. Nonetheless, the simultaneous execution of dual cognitive tasks leads to balance disruption in both eyes-arm closed positions.
