The latest Hytro Performance Podcast episode featured a compelling interview with James Hudson, Performance Nutritionist and Recovery Sports Scientist at Gloucester Rugby. During the conversation, Hudson delved into the unique implementation of Blood Flow Restriction (BFR) Training at Gloucester Rugby, emphasising its role in enhancing athlete recovery and performance, shedding light on how the club leverages it to optimise their players' physical conditioning and maintain peak performance across a gruelling rugby season.
Understanding BFR at Gloucester Rugby
James Hudson combines nutrition and recovery science to ensure athletes are always performing at their best. In a recent research collaboration with Hytro, Hudson explored the benefits of BFR to enhance recovery and performance for the team. Hudson detailed how Gloucester Rugby has been integrating BFR into their training programme, particularly during pre-season.
"We looked at how the preconditioning effect of using Hytro BFR before the players did some of the training sessions through pre-season affected the results of in-sessions," Hudson shared. This type of preconditioning helps athletes maximise the output of their training. For instance, Hudson described how the team conducted a study using BFR before short bursts of prowler pushing—an exercise that requires pushing heavy resistance over short distances. “By the later reps in the sets, they were able to move that object quicker over time,” he explained, revealing how BFR improved the players' power endurance. This is significant as rugby demands repeated high-intensity efforts over a prolonged period.
James and the Gloucester team have focused primarily on the use of BFR in combination with heavy lower limb resistance training. The results of the research were compelling: "We saw some really interesting results around improvements in bar speed," Hudson said, referring to how quickly players could lift weights in movements like the squat. He noted that this increase in bar speed points to improved neuromuscular efficiency, a critical factor in sports performance where speed and strength often determine success.
Integrating Heat with BFR
But in a fascinating twist, Hudson explained how the combination of BFR and heat exposure has impacted athletes’ perceptions of effort during their workouts. "We also looked at the effect of BFR in combination and with and without heat around weight sessions," he said. While the science behind heat exposure in training isn't new, the integration with BFR adds another dimension. "We saw how heat might have an effect on their perception of effort as well," Hudson added. This insight has helped Hudson, and his team refine recovery techniques, offering more nuanced ways to keep players at peak performance.
Shifting Mindsets Around Recovery
An intriguing aspect of Gloucester Rugby’s approach to programming is James’s emphasis on changing the athletes' perception of recovery. “I suppose where we've tried to move things is… it's not just those first couple of hours after a session. It's actually the whole 24 hours, 36 hours before they maybe then do that exposure in the gym or on the field,” he explained. This shift toward a continuous recovery model ensures athletes are always ready to perform, rather than only focusing on immediate post-training recovery.
Hudson emphasised how important it is for players to incorporate recovery into their overall routine. Gloucester Rugby’s athletes are encouraged to think of recovery as an ongoing process, lasting far beyond the immediate aftermath of a workout. “You need to guide them through incorporating certainly some new things like using the BFR into their current recovery strategies so that they can change that mindset,” he said. This method fosters a more holistic view of training, where recovery is as integral as the workout itself.
Tailoring Recovery to the Individual
One of the recurring themes in the podcast was the importance of individualising recovery techniques. Hudson noted, "It's not going to be the same for everybody. Some athletes are going to prefer different ways of using it.” This personalised approach allows athletes to find recovery strategies that work best for them, helping to maximise their performance without overloading their schedules with unnecessary or inefficient recovery methods.
Hudson also explained how Gloucester Rugby athletes utilise recovery techniques during travel, an often-overlooked aspect of sports performance. "When you're on the bus for 12, 18 hours after a game and you're taking a long time on flights as well to come back, having something which you can actually use on the move is a really big bonus," Hudson shared. By integrating Hytro BFR into their travel routine, players can actively recover during long trips, minimising downtime and keeping their bodies in top condition.
When asked how he balances traditional sports science with innovation, Hudson stressed the importance of evidence-based practices. "It is a quest for innovation. It’s not to be doing something different for the sake of it,” he said. This commitment to grounding new techniques in solid research ensures that any new methods—like BFR—are not only cutting-edge but also effective. “You have to make sure the foundation is evidence-based,” he added.
Hudson acknowledged the ever-evolving nature of rugby, with different styles of play emerging each season. Whether it's a more defensive-focused year or a shift towards a faster, more expansive game, physical preparation must adapt accordingly. "You have to evolve the game to be able to do that," Hudson said. This constant adaptation makes innovation a key part of the coaching and recovery process at Gloucester Rugby.
The Role of Breathing Techniques
One of the most exciting topics of conversation on the day was an often-overlooked aspect of athletic recovery—breathing techniques; where James shared a unique approach to stacking this recovery modality with BFR. “We want to activate that parasympathetic nervous system to try and get them to relax and come back down after they've lifted heavy because ultimately, we want them to sleep well,” Hudson explained. Incorporating breathing exercises into the Recovery BFR routine helps athletes transition from the high intensity demands of training to a more relaxed state, promoting better sleep and recovery.
These techniques are especially crucial during pre-season when athletes are pushing their limits in preparation for the upcoming season. Hudson highlighted the importance of sleep in recovery, noting that players who struggle to wind down could benefit from incorporating breathing exercises into their nightly routines. This focus on nervous system recovery is part of Gloucester’s holistic approach to player welfare.
Our pre-season discussion with James Hudson offered a fascinating glimpse into the future of athlete recovery, particularly with the use of Recovery BFR. By prioritising recovery as an ongoing process, integrating innovative techniques like BFR, and focusing on individual needs, Gloucester Rugby continues to push the boundaries of performance science. Hudson’s insights not only reveal the benefits of BFR but also underscore the importance of an evidence-based approach to sports innovation, where cutting-edge techniques are only as valuable as the results they produce.
Hudson's final advice to athletes sums it up best: “Incorporate [BFR] into sessions around your existing modalities... it can sit alongside all of those other elements.” For those looking to enhance their performance, the key lies in integration—using innovative tools like BFR as part of a comprehensive recovery strategy that supports athletes in their quest to reach new heights.
