A Controlled Trial of the Effects of Neuromuscular Training on Physical Performance in Male and Female High School Athletes.

ABSTRACT:

Background

Neuromuscular training (NMT) has demonstrated efficacy as an intervention to decrease the risk of anterior cruciate ligament injuries and improve sports performance. The effect of this training on the mechanisms that contribute to improved physical performance has not been well defined.

Hypothesis

Athletes in the NMT group will have better mechanisms of fundamental movements and agility tests that may contribute to improved sports performance.

Study design

Prospective cohort study.

Level of evidence

Level 2.

Methods

Eight high school teams (111 athletes, 53% male, mean age 16 years) participated, with half performing NMT. Physical performance was measured using the dorsaVi ViPerform system, a US Food and Drug Administration-cleared wireless sensor system. Agility was assessed using a timed 3-cone test. Independent sample t tests were used to compare differences between the intervention and control groups.

Results

Matched pre- and postseason data were collected from 74 athletes after excluding athletes with injury and those lost to follow-up. Significant improvements were observed in the NMT group for loading/landing speed ratios during a single-leg hop test (right lower extremity = -0.19 [-0.37, 0.03], P = 0.03 and left lower extremity = -0.27 [-0.50, -0.03], P = 0.03). The control group had lower ground reaction forces compared with the NMT group (P < 0.02), while significant improvements were found in the NMT group for initial peak acceleration (P < 0.02) and cadence (P = 0.01) during a straight-line acceleration/deceleration test. For the 3-cone agility test, the postseason time decreased compared with preseason in the NMT group, whereas the time for the control group increased (-0.37 s vs 0.14 s, P < 0.00).

Conclusion

The results demonstrate that NMT administered by sports medicine clinicians can significantly improve some physical performance of fundamental movements in high school athletes.

Clinical relevance

Coaches should be trained to effectively deliver NMT in order to improve sports performance.

Project description:BackgroundEnhancing youth's physical fitness levels during childhood and adolescence through prior training programs can significantly optimize their athletic performance. The integrative neuromuscular training (INT) model is designed to improve neuromuscular function and prevent athletic injuries, and is superior to the traditional physical training method. This systematic review and meta-analysis aims to compare the effects of INT versus traditional physical fitness training (PT) on physical performance-related outcomes in young athletes.MethodsSix online databases (PubMed, MEDLINE, Embase, SPORTDiscus, Web of Science, PsycINFO) searched from inception through 15 January 2024. Meta-analysis was performed when data were available from two or more trials. Physical performance-related outcomes were analyzed using standardized mean differences (SMDs) and mean differences (MDs) with 95% confidence intervals (CIs). The certainty of evidence and quality of the included studies were rated using the GRADE scale and the revised Cochrane risk-of-bias tool respectively.ResultsSeventeen randomized controlled trials with 649 young athletes were included in the systematic review. Of those, 1 study showed a low risk of bias, 1 showed a high risk, and 15 showed some concerns. Compared to the PT group, INT significantly improved dynamic balance (MD = 7.29%, 95%CI 3.31 to 11.28, p < 0.001, I2 = 64.7%), static balance (SMD = -0.54, 95%CI -0.84 to -0.24, p < 0.001, I2 = 0.0%), jumping performance (SMD = 0.53, 95%CI 0.32 to 0.73, p < 0.001, I2 = 0.0%), sprinting capacity (SMD = -0.76, 95%CI -1.13 to -0.39, p < 0.001, I2 = 57.6%) and maximal strength (SMD = 1.01, 95%CI 0.35 to 1.67, p = 0.002, I2 = 81.9%%). No significant between-group differences were identified for agility and flexibility.ConclusionOur findings suggest that INT has the potential to be an effective training method to improve physical performance in young athletes. Moreover, further research is needed to determine the effects and associated doses for young athletes of different age groups.

Project description:ContextAnterior cruciate ligament (ACL) injuries are common in female athletes and are related to poor neuromuscular control. Comprehensive neuromuscular training has been shown to improve biomechanics; however, we do not know which component of neuromuscular training is most responsible for the changes.ObjectiveTo assess the efficacy of either a 4-week core stability program or plyometric program in altering lower extremity and trunk biomechanics during a drop vertical jump (DVJ).DesignCohort study.SettingHigh school athletic fields and motion analysis laboratory.Patients or other participantsTwenty-three high school female athletes (age = 14.8 ± 0.8 years, height = 1.7 ± 0.07 m, mass = 57.7 ± 8.5 kg).Intervention(s)Independent variables were group (core stability, plyometric, control) and time (pretest, posttest). Participants performed 5 DVJs at pretest and posttest. Intervention participants engaged in a 4-week core stability or plyometric program.Main outcome measure(s)Dependent variables were 3-dimensional hip, knee, and trunk kinetics and kinematics during the landing phase of a DVJ. We calculated the group means and associated 95% confidence intervals for the first 25% of landing. Cohen d effect sizes with 95% confidence intervals were calculated for all differences.ResultsWe found within-group differences for lower extremity biomechanics for both intervention groups (P ≤ .05). The plyometric group decreased the knee-flexion and knee internal-rotation angles and the knee-flexion and knee-abduction moments. The core stability group decreased the knee-flexion and knee internal-rotation angles and the hip-flexion and hip internal-rotation moments. The control group decreased the knee external-rotation moment. All kinetic changes had a strong effect size (Cohen d > 0.80).ConclusionsBoth programs resulted in biomechanical changes, suggesting that both types of exercises are warranted for ACL injury prevention and should be implemented by trained professionals.
