Neuromuscular Efficiency For Enhancing Performance
Neuromuscular efficiency refers to the ability of the nervous system to effectively recruit and synchronise muscle fibres to produce force and movement. Imagine trying to lift a heavy box: neuromuscular efficiency is akin to having a well-coordinated team where everyone pulls together at the right time and with the right effort, making the task easier and more effective. This process involves a seamless interaction between the brain, spinal cord, nerves, and muscles. Neuromuscular efficiency is critical for athletic performance, as it determines how well the body can generate power, maintain balance, and execute coordinated movements efficiently.
Mechanically, neuromuscular efficiency hinges on several factors:
Improving neuromuscular efficiency enhances performance by enabling the body to produce force more quickly, sustain power output, and execute complex movements with reduced energy expenditure. For athletes, this translates to better speed, strength, and agility. For non-athletes, it can lead to improved functional fitness and reduced risk of injury.
French Contrast Training (FCT) is a training method specifically designed to optimise neuromuscular efficiency by leveraging the principle of post-activation potentiation (PAP). PAP occurs when a heavy resistance exercise primes the nervous system, enhancing subsequent explosive movements. FCT combines high-load strength exercises with plyometrics, loaded jumps, and assisted plyometrics in a single session, targeting both fast-twitch and slow-twitch muscle fibres.
This training method enhances neuromuscular efficiency by:
A recent study explored the effects of FCT on the performance of male field hockey players. The objective was to examine how a 12-week FCT programme could enhance specific biomotor and physiological parameters, including muscular strength, speed, anaerobic power, resting heart rate, and vital capacity.
The study involved 30 male college-level field hockey players, divided into a treatment group (TG) and a control group (CG). Male players were chosen due to their participation in high-intensity intercollegiate competitions, which necessitated the specific performance metrics targeted by the study. However, this focus on male athletes may limit the generalisability of the findings to other populations, such as female players or recreational participants, whose physiological and training responses could differ. Participants in the TG underwent three FCT sessions per week, while the CG continued with their regular routines. The FCT sessions included a combination of back squats, countermovement jumps, loaded jumps, and band-assisted jumps, performed with progressive overload.
The findings were significant. The TG showed marked improvements in muscular strength, speed, anaerobic power, and vital capacity. These results highlighted FCT’s ability to enhance both physical and physiological variables crucial for field hockey performance. Interestingly, there was no significant change in resting heart rate, likely due to the players’ already high fitness levels.
The second study investigated the effects of uphill-downhill and resisted sprinting on sprint performance. It found that resisted sprinting improved neuromuscular adaptations, particularly in acceleration phases, by placing high force demands on the nervous system and muscles.
These findings align with the principles of FCT, as both training methods aim to enhance neuromuscular efficiency by leveraging high force demands and improving neuromuscular coordination. Specifically, the sprinting study’s focus on resisted sprints mirrors the FCT approach of combining resistance and explosive movements. Both methods enhance motor unit recruitment, firing frequency, and coordination, which are crucial for boosting acceleration, power, and overall performance. The study’s demonstration of improved force production and coordination supports the inclusion of resistance and dynamic elements, such as those in FCT, to maximise performance outcomes.
While FCT is highly effective for athletes, its principles can be adapted for general clients aiming to improve their gym performance or excel in recreational sports. Trainers can use lighter loads and simplified movements to suit clients’ fitness levels, focusing on exercises that build strength, power, and coordination. For instance:
This adaptation ensures clients can safely improve their neuromuscular efficiency, enhancing their ability to perform compound lifts, agility drills, and dynamic movements in social sports or general fitness settings.
A 12-week FCT programme can be divided into four phases, each lasting three weeks. Each session includes a heavy resistance exercise, plyometric drill, loaded jump, and assisted plyometric movement.
Here are two examples of FCT sets:
Each session begins with a thorough warm-up and ends with mobility and recovery work. Recovery periods between sets are kept short to maintain the PAP effect.
Neuromuscular efficiency is a cornerstone of physical performance, enabling athletes and fitness enthusiasts to generate force, execute movements, and sustain power with precision. French Contrast Training stands out as an effective method to enhance this efficiency, combining resistance and plyometric exercises to target the nervous system and muscle fibres simultaneously.
The studies reviewed underline FCT’s potential to improve key performance metrics such as strength, speed, and power. While originally designed for athletes, FCT principles can be adapted for general clients, offering a scalable approach to achieving fitness goals. For example, a recreational runner might benefit from improved neuromuscular efficiency by enhancing their stride power and coordination, leading to better endurance and speed during a 5K race. Similarly, a gym enthusiast focusing on functional fitness could use an adapted FCT programme to improve their ability to lift weights explosively or perform dynamic movements like box jumps, which carry over to both gym and daily activities. A structured, periodised FCT programme not only boosts performance but also provides a versatile framework for trainers to implement with clients of all fitness levels.
