Bandeja and vibora: the biomechanics of padel's overheads

You have won the net, the opponents lob, and you have about a second to choose: smash, bandeja, or the vibora you saw in a highlight reel. For most intermediate players the choice matters more than the swing. This guide covers what each overhead is for, how the body produces it, where the load lands and how to fix the common faults, using the research that exists and saying plainly where it runs out.

Note: The biomechanics of padel overheads is a thin literature. There are solid notational studies of what professionals hit and how often it works, but almost no lab measurements of the bandeja or vibora themselves. Where this guide relies on tennis serve research or on coaching consensus, it says so.

What each shot is for

The bandeja: keep the net

Researchers define the bandeja (often called the "tray" in English papers) as an overhead hit without a bounce on the dominant side, with the racket face opened upwards and a slice effect, and with a lower impact point than other smashes (Sánchez-Alcaraz et al., 2020).

That study analysed 1,015 smashes from eight World Padel Tour finals in 2019. The bandeja was the most used overhead: 291 of 522 for men (55.7%) and 339 of 493 for women (68.8%). Its outcome profile is the key point. For men, 89.7% of bandejas kept the rally going, 7.2% were winners and 3.1% were errors. For women the figures were 87.0%, 6.8% and 6.2% (Sánchez-Alcaraz et al., 2020). The LTA calls it "the antidote to the lob" and quotes the same 69% share for women's overheads (LTA Padel).

A 2024 study of 3,239 professional points found bandejas in about 50% of men's and 60% of women's points. The authors call them "key defensive actions to maintain the net after a lob" (Martín-Miguel et al., 2024). In national first-category matches, winning pairs played a higher share of bandejas than losers (8.7% of strokes against 6.0%) (Ramón-Llin et al., 2020).

The bandeja is positional: its job is to win the next ball, not this one.

The vibora: pressure the corner

The vibora is the more aggressive cousin. Coaching sources describe it as a slice smash aimed at the corner, played when the opponents give you an easy lob while you are still fairly close to the net (The Padel School; The Padel School). The usual distinction is spin: side-spin on the vibora, slice or backspin on the bandeja (Padel.FYI).

Here the research is silent. None of the large professional studies reviewed here records the vibora as its own category. The 2020 smash study used four types: tray, flat, topspin and off-the-wall (Sánchez-Alcaraz et al., 2020). The 2024 study includes a "topspin bandeja" that appears in roughly a fifth of points, but it is not clear that this matches what coaches call a vibora (Martín-Miguel et al., 2024). There is no reliable published winner or error rate for the vibora.

The flat smash and the por tres: finish

The flat smash is the point-ender. In the 2020 study, 51.8% of men's flat smashes and 33.3% of women's were winners. Topspin smashes produced 41.2% and 29.2% winners. Effectiveness fell significantly as players moved away from the net, especially for the flat smash (Sánchez-Alcaraz et al., 2020). The por tres (x3) is the smash that bounces and leaves the court over the 3 m fences. Professionals used it in only 4 to 9% of points (Martín-Miguel et al., 2024).

About 60% of professional smashes were hit from the middle zone, because good defenders lob high and deep (Sánchez-Alcaraz et al., 2020). If the pros cannot finish reliably from there, neither can you.

The kinetic chain: legs to wrist

What padel research has measured

Very little. The only padel 3D study of these shots located for this guide filmed one world-class player for two trials each of a "tray-smash" and a "hook-smash", mainly to describe stroke phases. It noted the hook-smash was usually struck with the feet off the ground (Gianikellis & Skiadopoulos, 2016); whether that means the modern vibora is not stated. A 2024 motion-capture study found that experience changed shoulder rotation and scapular tilt during strokes, but the abstract does not separate bandeja from vibora (de Sire et al., 2024). A 2022 scoping review found only two biomechanics studies among 77, neither on overheads (García-Giménez et al., 2022).

What tennis tells us

The tennis serve is the closest well-studied movement. In a review of the serve, Kovacs and Ellenbecker summarise Kibler's work: the legs and trunk produce 51 to 55% of the kinetic energy and force delivered to the hand. Modelling suggests a 20% drop in trunk energy would need a 34% increase in velocity, or 70% more mass, to deliver the same energy to the hand (Kovacs & Ellenbecker, 2011).

Elliott sets out the sequence: leg drive and trunk rotation, then the upper arm, then forearm pronation and upper-arm internal rotation, then the hand. In a power serve, upper-arm internal rotation contributes about 40% of racket speed at impact and hand flexion about 30% (Elliott, 2006). The big segments build the energy; the last links turn it into racket speed.

Flat, slice and kick serves look much the same in the lower body. The main differences sit higher in the chain, at the racket face angle set by forearm pronation and shoulder internal rotation (Kovacs & Ellenbecker, 2011). A reasonable inference, not yet tested in padel, is that the bandeja, vibora and smash share the same base of legs and trunk and differ mainly in the arm and racket face.

Link by link

Legs: load the back leg as you retreat, then push forward through contact. The LTA advises using the shot's momentum to move back towards the net, level with your partner (LTA Padel).
Trunk: the side-on turn stores rotation. A clinical review describes overheads as a loading phase of spinal extension and trunk twist followed by a rapid flexion and rotation of the trunk, which acts as the bridge between legs and arm (Cocco et al., 2024).
Shoulder: get the racket up early. The LTA image is holding a plate above your head as if catching food on it (LTA Padel).
Elbow: keep it high and extending into contact. One coaching source warns that a bent elbow, rising up to the ball, makes slice "physically impossible" (The Padel School).
Wrist: relatively quiet on the bandeja. The vibora uses more wrist, which coaching sources say makes the timing harder (Padel.FYI).

Contact point, racket face, swing path and spin

Bandeja

Contact is around forehead or eye height, with the racket face slightly open and the swing starting above the contact point (The Padel School; LTA Padel). The path is high to low, but the racket travels across the body rather than straight down, finishing wrapped around you "like a scarf". That path is what adds the underspin (LTA Padel). You do not need much spin. A little slice with the right speed and direction is enough (The Padel School).

Coaches say contact "in front". But a tracking study of 14,478 shots by 48 recreational players found that higher-level players struck the bandeja almost level with their centre of gravity (−0.01 m on average), while novices struck it 0.24 m further forward. The study measured horizontal position only, not height (Sánchez-Alcaraz et al., 2021). The practical message: "in front" does not mean reaching forward with the arm. Move your feet back until the ball drops into your hitting zone.

Vibora

The racket comes around the outside of the ball rather than from underneath (The Padel School), adding side-spin to the slice (Padel.FYI). One coaching description puts contact at "three o'clock" on the ball, at eye level (Padel.FYI). The Padel School describes two versions. In the low-contact vibora you strike at head height and the ball stays low in the corner. In the high-contact version you strike slightly above head height, and the ball travels faster and tends to hit the side fence (The Padel School).

Flat smash and por tres

Research definitions describe the smash as hit with the arm outstretched over the head, flat or with topspin (Sánchez-Alcaraz et al., 2021); the flat smash is struck at the highest possible point with a lot of power (Sánchez-Alcaraz et al., 2020). The contact is higher and the swing is more downward than on either slice overhead.

Footwork: side-on, then back

Turn first. As soon as you read the lob, turn to face the side wall (LTA Padel).
Move back with side steps or crossovers, the standard padel patterns for covering ground sideways (The Padel School). Backpedalling square to the net leaves your shoulders facing the wrong way.
Get behind the ball. Take purposeful steps to create space for contact and move back early (The Padel School). For the vibora, take one extra step back so the ball is in front of you and your body can move forward to the net after contact (The Padel School).
Recover forward. Contact should carry you back towards the net, level with your partner.

Bandeja vs vibora vs smash

	Bandeja	Vibora	Flat smash / por tres
Purpose	Keep the net, reset the point	Pressure the corner, force a weak reply	Win the point outright
Contact point	Forehead to eye height, lower than a smash	Head height (low version) to slightly above	Highest point, arm fully extended
Racket face and path	Slightly open, high to low, across the body	Around the outside of the ball	Flat, driving down and through
Spin	Light slice or backspin	Side-spin plus slice	Little or none (flat), or topspin
Pro evidence	87 to 90% continuity, 3 to 6% errors	No published category data	Flat smash: 33 to 52% winners, falling with distance from the net (no separate por tres data)
Risk	Low, but a short or slow ball gets counter-attacked	Medium: timing-sensitive, more wrist	High away from the net, gives up position if it comes back

Figures: Sánchez-Alcaraz et al., 2020. The risk row is coaching judgement, not measured.

Common mistakes and fixes

Hitting the bandeja like a smash. The LTA advises taking pace off and focusing on placement (LTA Padel). The same error affects the vibora: a common fault is believing it should be hit as hard as possible (The Padel School). Fix: judge the shot by where the ball bounces and how low it stays, not by how fast it travels.

Not getting back far enough. Contacting the ball too far behind you costs forward momentum, and watching your previous shot instead of moving back early is the usual cause (The Padel School). Fix: turn early and take one more step than feels necessary.

A bent elbow at contact. Rising up to the ball removes the high-to-low path needed for slice (The Padel School). Fix: start the racket above the contact point and extend into the ball.

Square shoulders. Without the side-on turn, the trunk cannot contribute and the arm does all the work. This is the tennis kinetic-chain principle applied to padel. Fix: point the non-hitting shoulder at the side wall before the ball drops.

The wrong shot from the wrong place. Smash effectiveness falls significantly with distance from the net (Sánchez-Alcaraz et al., 2020). Fix: from a deep lob, play the bandeja. Save the vibora for shorter lobs and the flat smash for balls close to the net.

Drills

1. Defend the net (LTA). Two players at the net, two at the back. The back team feeds a lob; the net team must play a bandeja that lands beyond the service line, then the point is live. Swap roles every two points; first to 10 wins (LTA Padel).

2. Shadow footwork ladder. Without a ball: split step at the net, turn side-on, two crossovers back, shadow a bandeja at eye height, move forward to the net. Do 3 sets of 8 until the turn is automatic.

3. Call the lob. A feeder mixes deep, medium and short lobs. Call "bandeja", "vibora" or "smash" before contact, then play it. Score a point for the right choice and another for a ball that lands past the service line and stays low.

4. Low vibora to the corner. Mark a zone in the opponents' corner, about a metre from both walls. Feed medium-short lobs and play only the low-contact vibora at head height. Count balls that land in the zone and reach the back glass below waist height. Pace does not score.

Shoulder and elbow load

Padel injuries are common. A 2023 systematic review of eight studies (2,022 participants) found 3 injuries per 1,000 hours of training and 8 per 1,000 matches. The elbow was the most frequent site, followed by the knee, shoulder and lower back, and most injuries affected tendons or muscles. The authors note that the evidence base is limited (Dahmen et al., 2023).

A clinical review argues that the smaller court increases how often players hit overheads, and so how often the shoulder combines abduction with external rotation. Repeated elevation above 90° narrows the space under the acromion, with potential impingement of the rotator cuff and bursa. The same review cites a survey of 950 amateur players that found the shoulder was the second most common upper-body injury site after the elbow (Cocco et al., 2024). It also links medial elbow tendinopathy to explosive wrist flexion with forearm pronation and heavy use of topspin and slice. That is a proposed mechanism, not a measured one, but worth noting if you hit a lot of wrist-driven viboras. The 2024 motion-capture study concluded that the large ranges of motion in overhead strokes could raise the risk of labral (SLAP) lesions, impingement and loss of internal rotation, and that correct technique helps keep the head of the humerus stable (de Sire et al., 2024).

Tennis research points the same way, though it was not measured in padel. Elite servers with good front-leg drive have lower anterior shoulder and medial elbow loads, and a front-knee bend of more than 15° during loading is recommended. Elite tennis players can lose up to 10 to 15° of shoulder internal rotation and total rotation, and posterior shoulder stretches such as the sleeper and cross-arm stretch help counter this (Kovacs & Ellenbecker, 2011). Because the external rotators are much smaller than the internal rotators, they need specific strengthening (Elliott, 2006).

The practical points:

Let your legs and trunk do the work rather than the arm alone.
Build external rotation and scapular strength into your gym work, and keep up posterior shoulder mobility.
Limit vibora reps while learning it; the wrist-driven action is a plausible source of extra elbow load.
Persistent pain on the outside of the elbow or the front of the shoulder needs a physiotherapist, not more practice.

The short version: the bandeja keeps you at the net, the vibora pressures the corner, and the smash finishes the point when you are close enough. Pick the right one and the swing gets easier.
