Athletic Development for Youth Athletes

Our Youth Athlete Programs

We offer two core development pathways designed to help young athletes (ages 8–17) build speed, agility, strength, and resilience. Each program complements the other, giving athletes the tools to perform at their best on the field, court, or track.

Program 1: Speed & Agility Training

Goal: Make athletes faster and more agile where it matters most—those first 3–5 steps and game-speed changes of direction. Research and practice show most team-sport sprints reach ~80% of max speed within the first few steps, so we emphasise early acceleration, posture, and footwork before layering on volume.

How we train:

- Technical development:
Sprint mechanics (drive, projection, posture), COD positions, and reactive agility drills that translate to sport scenarios.

- Physical development: Progressive exposure to maximal sprinting (including upright sprinting over 20m+) to build speed safely and effectively. Plyometrics are included to grow lower-body power.  

- Objective feedback: Timing and video feedback to coach details, track 10m/20m, and monitor max speed so athletes and parents see progress.  

What a session can include

Warm-up and drills → technical acceleration work → change-of-direction/agility scenarios → plyometric power block → speed exposures → cool-down & feedback.

Expected outcomes
Cleaner mechanics, faster first steps, improved agility, and measurable gains in short sprint times.

Program 2: Gym-Based Athletic Development

Goal: Build strength, coordination, and robustness that carry over to faster sprinting, better jumping, and fewer time-loss niggles.

How we train:

- Movement quality first:
Age-appropriate patterns (squat, hinge, push, pull, brace) taught with great technique and supervision.

- Strength and power: Carefully progressed loads and tempos; med-ball work and jumps to connect strength to speed.  

- Resilience: Accessory work for hamstrings, hips, and trunk to support sprinting and change-of-direction demands. Sessions complement the speed work above and reduce injury risk.

Expected outcomes
Improved force production, better control, and durability across a full season.

How we track progress

We use simple, objective markers (e.g., 10m and 20m sprint times and periodic video analysis) so athletes understand what’s improving and why. Parents receive clear updates.

Coaching approach

Led by an experienced S&C coach with a track record across youth and elite performance, we combine individualised coaching with a supportive environment—similar to how your Small Group PT model prioritises coaching quality and structure.

Unit Health & Performance has been brilliant for building my son's pace and agility for playing football. The coaching is both professional and encouraging and I would highly recommend Vitalij to any athletes looking to improve their performance and technique.

Athlete360 is a fantastic resource for any budding sportsperson. Vitalij has great attention to detail, explains things very clearly and tailors the coaching to the athlete. Whether your child is a sprinter, ice hockey player, rugby player, footballer or any sport he will devise a training plan suited to your child’s needs. My son plays rugby predominately and Vitalij has improved his acceleration, change of direction, sprinting generally and also his sprint power. Overall having a huge positive impact on his ability to play the game. My son thoroughly enjoys every session and the benefits are obvious.

Athlete360 Performance has proved to be a fantastic addition to my sons training regime. Jonas is 12 and plays ice hockey and following lockdown we saw a Facebook advert to try some of the speed sessions.We signed up not knowing what to expect, but it was a great session. Since then Vitalij has worked closely with Jonas to increase his speed, strength and power. Crucially Jonas loves the training and is motivated every week to go and work hard.In the ice we have seen a huge increase in his strength and confidence in what he can do. If you are considering it , then try it and see if it fits for your child.

Vitalij is a critical part of the sporting offer at Worksop College. His work ethic, knowledge and patience have been vital in driving both the sport for life ethos but also the performance element of our programme. As a small school we need to get the most out of every pupil physically in order to compete and he does a great job of this. I know that our teams and individual athletes really benefit from his background, expertise and drive.

It is an honour finally being coached by a strength and conditioning professional who is knowledgeable and can  focus on my physical development for swimming. When I started working with Vitalij, his individualised and scientific approach to my training helped me to improve my performance by increasing my power which I noticed through faster starting times off swimming blocks which had a huge impact on my comeback into swimming as a sprinter. Other than him being a great coach, he is a very nice person and working with him is a pleasure as has a very personal approach to everybody and can adapt to different athletes needs and personalities. I would highly recommend Vitalij's services to anyone who is looking to develop they physical qualities to improve their sport performance.

He is the most knowledgeable strength and conditioning coach I have ever met. Vitali’s knowledge and experience is all rounded and his training programs are very effective in terms of enhancing my sprinting technique,speed, strength and power as a 100m sprinter. He is a true professional.

Vitalij had a vital role in my success on playing football in England and in Europe. He assessed my form when I first met him and wrote a workout program that helped push me to a higher level of my fitness, strength and agility. I learnt a great amount from Vitalij about my body and how I can reach the next level in football physically and mentally by being consistent in what I do in the gym and on the pitch.

As a parent of a sports scholar at Worksop College, I have been immensely impressed with the work that has been done by Vitalij with my 12 year old son. He is fitter, quicker more dynamic and powerful for his body weight.
