What is the berkoff swimmer technique
The berkoff swimmer is a starting block setup in which the athlete sits on the front edge of the block with minimal support from the feet, creating a more forward and streamlined position. Developed by sprint backstroke champion David Berkoff and popularized in the 1980s, the style emphasizes an aggressive forward shift at the start to reduce underwater distance and maintain high velocity. Unlike traditional setups that rely heavily on the rear foot and higher hips, the berkoff swimmer uses a longer slide and lighter hand contact, aiming to align the body earlier into a horizontal posture off the block.
Key benefits and why swimmers adopt it
Coaches and athletes use the berkoff swimmer to gain a quicker start, a more horizontal underwater path, and reduced frontal resistance. By sitting farther forward and minimizing vertical displacement at the takeoff, swimmers can maintain momentum from the block into the water and strengthen their breakout. The technique is particularly valuable in short-distance events where every tenth of a second matters, and it can help reinforce clean entry habits and efficient underwater dolphin kicks. For many programs, it is one option in a broader menu of starting styles rather than a one-size-fits-all solution.
How to set up in the berkoff swimmer position
Effective execution begins with a stable yet forward-leaning setup on the block, focusing on consistent hand, hip, and foot placement. Because the technique relies on a longer slide and reduced rear-foot support, it rewards precise body control and comfort with an active, early forward shift. The following steps outline a repeatable process for mounting the block and finding the right berkoff swimmer posture.
Block setup and body positioning
Position your feet at the front of the block so the toes are just behind the edge, allowing for a long, low slide forward. Place both hands close together near the front of the block, wrists slightly in front of the shoulders, and lower your hips forward until your torso angles down toward the water. Your head should be neutral or slightly lifted, aligned with the spine, so your gaze is focused forward without collapsing the chest. The goal is to create a long, streamlined line from the hands through the hips, making the first movement a controlled fall forward rather than a vertical jump.
Initiating the start motion
Begin the start by pressing through your hands and lightly engaging the rear foot to tilt the body forward while keeping the center of mass moving ahead of the block edge. Allow your hips and shoulders to travel over the water line early, maintaining tension through the core to avoid sagging at the waist. As you slide forward, coordinate a slight backward push with your feet so that your acceleration is smooth rather than abrupt. Avoid delaying the forward motion, because hesitation can raise the hips and add frontal resistance. Instead, emphasize an immediate and continuous horizontal drive that carries you into the water at an efficient angle.
Entry and underwater execution
Once you are past the block, reach forward with the hands and enter the water in a tight, streamlined position, head between the arms. Aim for a clean, low entry that avoids splash and splash-related drag, then initiate a strong underwater dolphin kick sequence to preserve the momentum gained at the start. Keep the body aligned, with the chest pressing forward and the head still, to ensure each kick moves you efficiently beneath the surface. Manage your surfacing timing so that you break out only after you have built sufficient underwater speed and are on a flat, forward trajectory toward the surface.
Comparisons with other starting styles
When evaluating the berkoff swimmer, it helps to contrast it with more traditional setups, especially the common rear-foot–dominant style used by many elite sprinters. The table below summarizes structural and tactical differences that distinguish the approaches, focusing on posture, slide length, foot support, and common performance outcomes.
Starting style comparison table
| Attribute | Berkoff Swimmer | Traditional Rear-Foot Style | Typical Performance Context |
|---|---|---|---|
| Primary block posture | Forward-seated, low hips, longer slide | Higher hips, shorter slide, more upright torso | Balance between forward lean and stability |
| Hand placement on block | Close together near block front, light touch | Wider grip, firmer support | Preferred feel and timing for the swimmer |
| Rear foot support | Minimal, edge of toes or none | Strong drive through the rear foot | Influence on initial force direction |
| Slide length | Long | Short to moderate | Impacts forward momentum off the block |
| Common use cases | Backstroke, freestyle sprinters, distance-focused breakout | Sprint freestyle, butterfly, diverse events | Event and preference dependent |
Practical tips for integrating the technique
If you are considering adding the berkoff swimmer to your routine, start with low-volume block practice and prioritize clean body alignment over raw speed. Use a video review or coach feedback to confirm that your hips are traveling forward rather than dropping, and adjust your foot position if your entry becomes too steep or splashy. Gradually increase intensity while managing volume so that your start mechanics remain consistent across multiple repetitions. Pay attention to your underwater dolphin kick count and surfacing depth, making small tweaks that keep your breakout fast and efficient.
Common considerations and troubleshooting
Because the berkoff swimmer involves a longer slide and reduced rear-foot pressure, some swimmers experience timing issues or feel less stable at the initial drive. If your entry is erratic or your underwater path veers to one side, check your hand and hip symmetry on the block and ensure that your head remains steady. Overreaching with the hands can strain the shoulders, so focus on reaching forward from the shoulders without locking the elbows aggressively. If discomfort persists, adjust your foot position toward the center of the block or consult a coach to refine your block timing and body angles.
When it may not be the right choice
The berkoff swimmer can be highly effective in certain contexts, yet it is not ideal for every athlete or every event. Swimmers who struggle with maintaining a tight streamline during the underwater phase, or who experience shoulder discomfort with a forward-seated start, may find other block setups more sustainable. Relay legs, individual medley events, or pools with longer approach distances can also influence which start style delivers the best overall result. Decisions about adopting or continuing the berkoff swimmer should weigh technique comfort, event demands, and coaching guidance rather than relying on a single approach for all situations.
Takeaway on the berkoff swimmer
Used thoughtfully, the berkoff swimmer can enhance a swimmer’s start by promoting an early horizontal posture, a longer slide, and a clean underwater breakout. Success with this style depends on precise setup, consistent practice, and careful attention to alignment and entry quality. By balancing the technique’s advantages with individual biomechanics and event requirements, swimmers and coaches can decide whether it supports their goals as a reliable tool in the starting toolkit.
