Injuries, Matches Missed and the Influence of Minimum Medical Standards in the A-League Professional Football: A 5-Year Prospective Study
Conclusions: The introduction of “Minimum Medical Standards” in the A-League had a favorable effect on the number of total, hamstring, knee and ankle injuries and on the number of matches missed due to these injuries, but not on the number of groin injuries. The costs related to time-loss injuries and related matches missed remained high.,Results: The total number of time-loss injuries and matches missed rose from 129 and 506 respectively in 2008 - 2009 to 202 and 1110 in 2010 - 2011. Following the introduction of ‘Minimum Medical Standards’, both categories decreased (significantly for matches missed). These time-...

Comparison of the Effects of Resistance Exercise Orders on Number of Repetitions, Serum IGF-1, Testosterone and Cortisol Levels in Normal-Weight and Obese Men
Conclusions: Performing large muscle group exercises first in RE training and progressing to small muscle group produced greater anabolic hormonal response relative to reverse sequence in normal-weight young adult men. Anabolic hormonal response to REOs was blunted in the obese group.,Results: REOs did not affect number of repetitions in none of the groups. The average rating of perceived exertion was higher for protocol B in both groups. IGF-1 and testosterone increased immediately post exercise for both protocols and in both groups, however immediately post exercise increase in IGF-1 and testosterone were lower in obese ...

Cardiorespiratory Fitness and Body Composition of Soccer Referees; Do These Correlate With Proper Performance?
Conclusions: It seems that the acquired scores of top-class referees may be influenced by multiple factors other than the laboratory findings of cardiopulmonary fitness and body composition.,Results: Among 78 participants (including 32 center and 46 side referees), mean and standard deviation of age, body mass index, percent of body fat, VO2max and performance scores were 37 ± 3.8, 23.6 ± 2.1, 20.7 ± 3.9, 59.9 ± 7.1 and 85.8 ± 0.25, respectively. No significant correlation between referees’ mean score and selected parameters were found.,Patients and Methods: In a cross-sectional study, all referees selected for the ...

A Comparison of Increases in Volume Load Over 8 Weeks of Low-Versus High-Load Resistance Training
Conclusions: This study indicates that low-load RT results in greater accumulations in VL compared to high-load RT over the course of 8 weeks of training.,Results: After adjusting for the pre-test scores, there was a significant difference between the two intervention groups on post-intervention total VL with a very large effect size (F (1, 15) = 16.598, P = .001, ηp2 = .525). There was a significant relationship between pre-intervention and post-intervention total VL (F (1, 15) = 32.048, P < .0001, ηp2 = .681) in which the pre-test scores explained 68% of the variance in the post-test scores.,Background: It has been ...

Knee Laxity Variations in the Menstrual Cycle in Female Athletes Referred to the Orthopedic Clinic
Conclusions: Despite numerous studies and research in the field of knee laxity and effects of female hormones, many researchers do not agree about the effect of female hormones on knee laxity. The current study also reported no relationship between female hormones and knee laxity, while statistics show fundamental difference between male and female athletes.,Results: The results of the current study showed that there is no significant difference in ACL laxity in female athletes in three phases of menstrual cycle; namely menstruation time, ovulation time and mid-luteal phase.,Patients and Methods: The present descriptive st...

Prevalence of Common Postural Disorders Among Academic Dental Staff
Conclusions: Our study revealed a high prevalence of postural disorders especially FHP, RSP and scoliosis among Iranian dental staff. The female dentists were less susceptible to FHP and scoliosis.,Results: The prevalence of the forward head posture (FHP), rounded shoulder posture (RSP), scoliosis and hyperlordosis were reported in 85.5%, 68.8%, 18.8% and 17.3% of the participants, respectively. A significant correlation was found between gender and FHP (P = 0.04) and also scoliosis (P = 0.009). On the other hand, a significant correlation was seen between weight and hyperlordosis (P = 0.007).,Patients and Methods: In a cr...

Management of In-Season Concurrent Rotator Cuff Tear With Shoulder Instability in Professional Contact Football Athletes; Respect the Career Goals!
Conclusions: The assumption that all pathology found at surgical exploration requires correction to play at elite level is not universally correct. We postulate that whilst rotator cuff deficiency has severe long-term sequelae, it is shoulder instability alone that prevents high level contact sports participation. Career goal management is an important part of managing elite level athletes. We have demonstrated that by careful management of the specific pathology preventing participation can allow elite athletes to achieve career goals without compromising long-term health.,Introduction: Professional sports injuries are us...

Kinetic Post-match Fatigue in Professional and Youth Soccer Players During the Competitive Period
Conclusions: Independent of their level, professional soccer players, need 48 hours to recover after an official match. Professionals gain more fatigue than young players after a match, but recover as fast. Thus, they recover more efficiently especially due to a better physical condition and fitness training. It is expected that the results showed in the study help elite soccer and fitness coaches to manage the training load of the team according to the match.,Results: for professionals, a soccer match elevated all physiological markers during the next 24 hours (P < 0.05); only HRrecovery remained significantly differen...

Morphine/Codeine Ratio, a Key in Investigating a Case of Doping
Conclusions: Analysis of codeine to morphine metabolism rate is needed when we are using morphine/codeine ratio to rule out abuse of narcotics. WADA should consider analysis for the CYP2D6 alleles (main metabolizer of codeine) in case of including morphine/codeine ratio in future prohibited list. The possibility of ultra-rapid CYP2D6 cannot be ruled out in certain results of morphine/codeine near the cut point.,Introduction: Consumption of codeine can lead to positive urine test for morphine in athletes. Morphine is classified as a prohibited doping drug while Codeine is not. Morphine/codeine ratio is used in forensic medi...

Acute Effects of Different Agonist and Antagonist Stretching Arrangements on Static and Dynamic Range of Motion
Conclusions: In conclusion, DFSE is probably the best stretching arrangement due to producing more post activation potentiation on agonist muscles and less muscle stiffness in antagonist muscles.,Background: Traditionally, stretching exercises are considered as basic components of warm up aiming to prepare the musculoskeletal system for performance and to prevent injuries.,Objectives: The purpose of this study was to examine the effects of different agonist and antagonist stretching arrangements within a pre-exercise warm-up on hip static (SROM) and dynamic range of motion (DROM).,Materials and Methods: Sixty trained male ...

Cross-Cultural Adaptation of the Micheli Functional Scale to Persian Language for Evaluation of Low Back Pain in the Young Athletes
Conclusions: The Persian MFS is valid and reliable for use in Persian-speaking young athletes with LBP.,Results: A sample of 100 young athletes with LBP with a mean age of 16.5 ± 2.5 years participated. Fifty young athletes without LBP completed the PMFS. There was no missing responses and floor or ceiling effects. There was a significant difference for the total PMFS scores between young athletes with and without LBP. A significant correlation was found between the total PMFS score and the VAS (r = 0.92) or the PFRI (r = 0.82; P < 0.001). A high internal consistency reliability (Cronbach α = 0.73), and excellent test...
