“…36,39 None of the soft tissue laxity studies were graded down for indirectness, as little information exists on the impact of BMI on soft tissue laxity, and studies have reached contradictory conclusions on the impact of activity level on soft tissue laxity. 23,65,67,69 Muscle injury/strength studies were graded down if the outcome measured was not generalizable to the other muscle strength study outcomes or if participants had more than a low recreational activity level because training can influence muscle strength. 23,69 In the soft tissue injury section, studies that were downgraded in 1 area were scored as “serious,” and those that were downgraded in 2 areas were scored as “very serious.” In the muscle injury/strength section, to distinguish quality-of-evidence scores among this body of literature, studies downgraded in both areas were scored as “serious,” and no studies were scored as “very serious.”…”

Background:Female patients are more likely than male patients to experience various musculoskeletal (MSK) injuries. Because MSK tissues are sensitive to the female hormones relaxin, estrogen, and progesterone, studies have examined whether hormonal contraceptives, which change female hormone levels, can alter the female MSK injury risk. These studies have reached contradictory conclusions, leaving unclear the influence of hormonal contraception on female MSK injury risk.Hypothesis:Hormonal contraceptives act to decrease female soft tissue injury risk and soft tissue laxity.Study Design:Systematic review; Level of evidence, 3.Methods:Reviewers searched for clinically relevant studies evaluating the relationship between hormonal contraceptive use and soft tissue injuries, soft tissue laxity, muscle injuries, and muscle strength in the PubMed, Cochrane, Scopus, CINAHL, and Embase databases. Studies meeting inclusion criteria were scored by 2 independent researchers for risk of bias, imprecision, inconsistency, and indirectness with a template designed using the British Medical Journal Clinical Evidence GRADE (Grades of Recommendation Assessment, Development and Evaluation) scoring system and GRADEPro guidelines. Scores were uploaded into the GRADEPro scoring system software, which calculated each study’s final GRADE score (very low, low, moderate, or high quality).Results:A total of 29 studies met inclusion criteria. Of the 7 studies evaluating oral contraceptive (OC) use and soft tissue injury risk, only 2 received a high quality-of-evidence score; all other studies received a very low score. The high-quality studies concluded that OC use decreases anterior cruciate ligament (ACL) injury risk. Only 1 of the 10 studies evaluating OC use and soft tissue laxity was found to have a high quality of evidence; this study determined that OC use decreases ACL laxity.Conclusion:Higher quality studies suggest that OCs decrease a female patient’s risk of ACL injuries and ACL laxity. The strength of these findings, however, is weak. Female patients are up to 8 times more likely to tear their ACLs than male patients. OCs may serve a therapeutic role in decreasing the sex disparity in ACL injury rates.

“…Concurrent exercise (CE) involves the combination of aerobic exercise (AE) and resistance training in the same training session [1]. CE is common practice among exercising individuals and athletes and increases physical performance and body composition [2][3][4][5][6]. However, previous studies have shown that performing AE before resistance training results in acute decreases in muscle performance [2,4,[7][8][9][10], possibly due to an increase in peripheral fatigue, AMP-activated protein kinase (AMPK) and Peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α) signaling and decrease in satellite cell activity [1].…”

We aimed to determine whether creatine supplementation influences lower-limb muscle endurance following an acute bout of aerobic exercise (AE) in young healthy men. Using a randomized, double-blind, placebo-controlled crossover design, 11 men (26.5 ± 6.2 years, body mass index 26.6 ± 2.1 kg/m2),with 12 months of experience in strength training (three times/week) and AE (two times/week) were randomized to receive creatine (20 g/day plus 20 g/day maltodextrin) and placebo (40 g/day maltodextrin) for 7 days, separated by a washout period of 14 days, before performing an acute bout of AE (30 min on treadmill at 80% baseline maximum velocity) which was followed by four sets of bilateral leg extension endurance exercise using a 10-repetition maximum protocol (10 RM)). There was a significant decrease in the number of repetitions performed in the third (Placebo: −20% vs. Creatine: −22%) and fourth set (Placebo: −22% vs. Creatine: −28%) compared with the first set (p < 0.05), with no differences between creatine and placebo. Additionally, no differences were observed between creatine and placebo for the total number of repetitions performed across all four sets (Placebo: 33.9 ± 7.0 vs. Creatine: 34.0 ± 6.9 repetitions, p = 0.97), nor for total work volume (Placebo: 3030.5 ± 1068.2 vs. Creatine: 3039.8 ± 1087.7 kg, p = 0.98). Short-term creatine supplementation has no effect on lower-limb muscle endurance following an acute bout of aerobic exercise in trained young men.

“…The results showed no acute interference in the signaling of contractile proteins and mitochondrial biogenesis indicators, which suggests that this combination may favor the optimization of adaptation. However, in a recent randomized clinical trial, 14 the effects on strength indicators and cardiometabolic risk factors associated with 8 weeks of RT only and combined HIIT and RT in premenopausal women were evaluated. The authors concluded that HIIT before RT did not cause any interference effects on strength gains or induce significant changes in body composition or blood pressure.…”

It has been shown that combined physical exercise is an efficient non-pharmacological approach in the context of public health, since it has demonstrated satisfactory results in the prevention, treatment and control of various morbidities. Therefore, it is essential to systematize current knowledge to enable professionals involved in the prescription of physical exercise to do so based on evidence. Thus, the objective of this study was to perform a systematic review of randomized clinical trials to verify changes in cardiometabolic risk factors induced by high-intensity interval training (HIIT) and resistance training (RT) in adolescents. The systematic search was performed in the following databases: Pubmed, ScienceDirect, Cochrane, LILACS and Scielo. Initially 933 studies were identified, then two researchers eliminated duplications and manuscripts that did not meet the eligibility criteria. Thus, two articles were included that met these criteria: a randomized clinical trial conducted with adolescents (10 to 19 years) of both sexes, an intervention lasting for at least four weeks, which prescribed HIIT and RT in the same session or not, and evaluation of at least one cardiometabolic risk factor. The results demonstrated that eight to 12 weeks of HIIT and RT without nutritional intervention were effective in significantly reducing waist circumference and body fat percentage. However, data pertinent to the efficacy of this combination on risk of developing type 2 diabetes mellitus and arterial hypertension are controversial. In view of the above, it is ascertained from the included studies that the combination of HIIT and RT has the potential to reduce cardiometabolic risk factors in adolescents; therefore, further studies should be conducted to determine the effectiveness of this prescription of physical exercise. Level of Evidence II; Systematic review of Level II or Level I Studies with discrepant results.
