In 1912, Swedish running pioneer Greta Johansson did not set world records – but as a coach and physiotherapist in the early Olympic movements, she demonstrated how targeted preparation and recovery shape performance. Concurrently, women in the physiotherapy profession early on established systematic warm-up and cooldown routines in clinics and sports clubs – a silent turning point: away from "just starting to run," towards planned activation and smart regeneration. Today, research confirms what practitioners have been demonstrating for decades: proper warm-up and cool-down are not time-wasters but precision levers for performance, protection, and longevity.

A warm-up is more than “a bit of movement.” It increases temperature, heart rate, and neural activation, and prepares joints and tendons for changes in load. Dynamic stretching dynamisches Dehnenmoving, active movements with controlled amplitude enhances mobility without dampening strength development. Static stretching statisches Dehnenholding a stretch position without movement temporarily elongates the muscle-tendon system but is critical prior to maximal efforts. PNF stretching PNFProprioceptive Neuromuscular Facilitation - alternating contraction and stretching to increase range of motion utilizes reflex mechanisms to improve ROM and movement control. The cool-down reduces circulatory load, promotes blood flow, and calms the nervous system; stretching techniques can specifically maintain mobility here. For high performers, this means: timing and technique of stretching determine explosiveness now and movement quality in the long term.

Insufficient warming up correlates with higher complications, more subsequent injuries, and longer recovery times – even in experienced athletes ^[1]. Conversely, a dynamic warm-up improves functional readiness and is associated with a lower injury rate and better performance ^[2]. Static stretching performed right before intense or strength-based workouts can dampen maximal performance – just 30 to 60 seconds per muscle group measurably reduce the torque of the quadriceps muscles ^[3]; longer hold times (e.g., 120 seconds) do increase ROM but are associated with drops in power parameters ^[4]. After training, the picture is more nuanced: meta-analyses so far show no clear additional benefit of stretching compared to passive recovery for muscle soreness or short-term strength restoration [Ref34025459; Ref16284645]. Nevertheless, targeted PNF or static stretching can improve acute mobility – a plus for technical precision, postural economy, and long-term joint health [Ref22687658; Ref23487249]. Hydration remains the invisible performance booster: even a 2% fluid deficit worsens thermoregulation, circulatory stability, and muscle work – with immediate consequences for performance and safety ^[5].

The evidence for warm-up has clearly emphasized its importance in recent years. A review highlights that dynamic warm-ups, as comprehensive, sport-specific activation, deserve preference over purely static routines because they simultaneously elevate muscular, neural, cardiovascular, and psychological systems – with the goal of increasing performance and reducing injuries ^[2]. Additionally, experimental data from elite female athletes show that combining dynamic stretching with vibration foam rolling enhances hamstring mobility, reduces muscular stiffness, and improves fatigue resistance – immediate, practically relevant effects for sprinting, jumping, and throwing sports ^[6]. Regarding stretching and performance before intense exertion, the timing component remains crucial: studies demonstrate that longer static hold times can reduce explosive strength and early force development, even if ROM increases ^[4]; just 30–60 seconds per muscle group significantly lower isometric and isokinetic peak moments ^[3]. Current evidence suggests that stretching is not superior to passive recovery regarding muscle soreness and short-term strength restoration during the cool-down [Ref34025459; Ref16284645]. Nevertheless, separate research indicates that PNF and static stretching consistently improve mobility – beneficial for technical refinement and prevention of restrictive movement patterns [Ref22687658; Ref23487249].

- Integrate dynamic stretching into the warm-up: 5–10 minutes after light cardio. Actively move the joints through their full, controlled range (e.g., lunges with rotation, leg swings, arm circles). Goal: increase temperature, stimulate the nervous system, and ensure movements are sport-specific ^[2]. Optional: Combine dynamic stretching with vibration foam rolling for more ROM, lower stiffness, and better fatigue resistance – especially in tight posterior chains ^[6].
- Avoid long static stretching before high-intensity or strength sessions: hold times ≥30–60 seconds per muscle group can diminish peak strength and explosiveness. Save static stretching for later [Ref18296954; Ref29721606].
- Conclude the workout with static stretching: 2–4 positions per major muscle group, holding each for 20–30 seconds while breathing calmly. Manage expectations: it relaxes and maintains mobility; the effect on muscle soreness or rapid return of strength is limited [Ref34025459; Ref16284645].
- Use PNF in the cool-down 1–2 times/week: Contract-Relax for 5–6 seconds, then sink into the stretch for 20–30 seconds. Ideal for hip flexors, adductors, and the posterior chain. This increases ROM and supports clean technique in complex patterns [Ref22687658; Ref23487249].
- Drink wisely: start well-hydrated, drink during exercise in relation to sweat loss (goal: <2% body weight loss), and replenish afterwards. Consider electrolytes in heat. This stabilizes circulation, thermoregulation, and muscle contraction – the foundation for performance and safety ^[5].

The next evolutionary step in warm-up/cool-down will be personalized: sensors, ROM profiles, and daily condition data will dictate the optimal mix of activation, mobility, and soothing. Expect more precise recommendations regarding stretching duration, sequence, and tools – as well as clear guidelines on when mobility maintenance enhances performance without costing explosiveness.
