“…On the other hand, a lower injury burden was recorded for the EG compared to the CG. It may be striking that significant differences were found in burden but not in injury incidence, an aspect that some authors attribute to both the duration of the training program and the number of players involved in the research [20]. Therefore, the increase in burden may be an important indicator of injury severity, even when injury incidence does not vary significantly [4,14].…”

“…Approaching the study of sports injuries in soccer from a multifactorial approach can be very interesting for physical trainers to optimize player performance [63] and to try to prevent injuries [10,[17][18][19][20][21][22]. Therefore, this study aimed: (1) to analyze the effects of a 12-week maximal strength-training program on injury incidence, injury burden, and physical fitness variables in semi-professional soccer players; and (2) to compare the RPE L and state of well-being between injured and non-injured players.…”

“…Likewise, players were instructed to take their last meal 3 h before the beginning of the tests, not to drink any caffeinated beverages, and not to perform intense physical exercise. A strength and conditioning specialist supervised the tests and gave verbal encouragement during all of the protocols [20].…”

“…Aiming to reduce the number and severity of injuries, the scientific literature has demonstrated a high interest in evaluating the efficacy of training strategies for injury prevention [10,[17][18][19][20][21][22]. In this regard, several research studies have revealed the potential of strength training to mitigate the severity of both muscle and joint injuries [17,21,23,24].…”

The aims of the study were to analyze the effects of a 12-week maximal strength- training program on injury incidence, injury burden, and physical fitness in semi-professional soccer players and to compare the perceived exertion load and well-being state between injured and non-injured soccer players. Twenty semi-professional male soccer players participated in this study. Participants were randomly allocated to an experimental group (EG, n = 10 players), who performed a maximal strength-training program, or to a control group (CG, n = 10 players), who only performed their regular soccer training. Physical fitness was measured at baseline and after the training program. In addition, the injury incidence, burden, training/match load, and the state of well-being of the players were recorded. The EG showed significant improvements in vertical jumps, change in direction ability, linear sprints, repeated sprint ability, isometric strength (p < 0.003; effect size = 1.78–11.86), and quadriceps–hamstring imbalance in both legs (p < 0.001; effect size = 2.37–3.71) in comparison to the CG. In addition, the EG players showed a significantly (p < 0.05) lower injury burden (p < 0.001, relative risk = 5.05, 95% confidence interval = 3.27–7.79). This study demonstrated the beneficial effects of a 12-week maximal strength-training program on physical fitness attributes and injury burden in semi-professional soccer players.

“…The literature has devoted considerable attention to the incidence of hamstrings injuries and reinjuries [3,4,7,12] as well as to their financial and performance-related costs [14][15][16][17]. The literature has also extensively focused on the primary prevention of hamstrings injuries [5,[71][72][73][74][75][76], but their number continues to grow [2,77], and thus we assumed that many studies would be found focusing on rehabilitation strategies. However, only 14 studies fulfilled eligibility criteria (12 randomized and two non-randomized with 730 participants), with a maximum of three studies per comparison.…”

Effectiveness of Conservative Interventions After Acute Hamstrings Injuries in Athletes: A Living Systematic Review

et al. 2023

Background Hamstrings injuries are common in sports and the reinjury risk is high. Despite the extensive literature on hamstrings injuries, the effectiveness of the different conservative (i.e., non-surgical) interventions (i.e., modalities and doses) for the rehabilitation of athletes with acute hamstrings injuries is unclear. Objective We aimed to compare the effects of different conservative interventions in time to return to sport (TRTS) and/or time to return to full training (TRFT) and reinjury-related outcomes after acute hamstrings injuries in athletes. Data Sources We searched CINAHL, Cochrane Library, EMBASE, PubMed, Scopus, SPORTDiscus, and Web of Science databases up to 1 January, 2022, complemented with manual searches, prospective citation tracking, and consultation of external experts. Eligibility Criteria The eligibility criteria were multi-arm studies (randomized and non-randomized) that compared conservative treatments of acute hamstrings injuries in athletes. Data Analysis We summarized the characteristics of included studies and conservative interventions and analyzed data for main outcomes (TRTS, TRFT, and rate of reinjuries). The risk of bias was judged using the Cochrane tools. Quality and completeness of reporting of therapeutic exercise programs were appraised with the i-CONTENT tool and the certainty of evidence was judged using the GRADE framework. TRTS and TRFT were analyzed using mean differences and the risk of reinjury with relative risks. Results Fourteen studies (12 randomized and two non-randomized) comprising 730 athletes (mostly men with ages between 14 and 49 years) from different sports were included. Nine randomized studies were judged at high risk and three at low risk of bias, and the two non-randomized studies were judged at critical risk of bias. Seven randomized studies compared exercise-based interventions (e.g., L-protocol vs C-protocol), one randomized study compared the use of low-level laser therapy, and three randomized and two non-randomized studies compared injections of platelet-rich plasma to placebo or no injection. These low-level laser therapy and platelet-rich plasma studies complemented their interventions with an exercise program. Only three studies were judged at low overall risk of ineffectiveness (i-CONTENT). No single intervention or combination of interventions proved superior in achieving a faster TRTS/TRFT or reducing the risk of reinjury. Only eccentric lengthening exercises showed limited evidence in allowing a shorter TRFT. The platelet-rich plasma treatment did not consistently reduce the TRFT or have any effect on the risk of new hamstrings injuries. The certainty of evidence was very low for all outcomes and comparisons. Conclusions Available evidence precludes the prioritization of a particular exercise-based intervention for athletes with acute hamstrings injuries, as different exercise-based interventions showed comparable effects on TRTS/TRFT and the risk of reinjuries. Available evidence also does not support the use of platelet-rich pla...
