In a randomized, counter-balanced and crossover design, 14 habituated English Premier 10League academy soccer players performed 15 x 30 m sprints (each followed by a 10 m forced 11 deceleration) on two occasions. Within 20 min of exercise cessation, players entered a WBC chamber 12 (Cryo: 30 s at -60°C, 120 s at -135°C) or remained seated (Con) indoors in temperate conditions 13 (~25°C). Blood and saliva samples, peak power output (countermovement jump) and perceptual 14 indices of recovery and soreness were assessed pre-exercise and immediately, 2 h and 24 h post-15 exercise. When compared to Con, a greater testosterone response was observed at 2 h (+32.5 ± 32.3 16 pg•ml

Whole-Body Cryotherapy in Athletes: From Therapy to Stimulation. An Updated Review of the Literature

“…On the contrary, in a randomized, counterbalanced and crossover design, 14 habituated English Premier League academy soccer players, Russell and colleagues found that a single WBC session (−135°C, 2 min), performed within 20 min after a repeated sprint exercise (15 × 30 m), increased salivary testosterone, yet had no effect on cortisol, blood lactate, and CK nor on performance (peak power output), recovery, and soreness perceptions (Russell et al, 2017). …”

Whole-body cryotherapy (−110 °C) following high-intensity intermittent exercise does not alter hormonal, inflammatory or muscle damage biomarkers in trained males

“…Several studies have investigated the physical, psychological, and physiological effects of WBC following exercise (for a review see [1,2,15]) Many [13,[16][17][18][19], but not all [20,21] have reported that WBC might facilitate the recovery process after exercise. Actually, for most biomarkers (e.g.…”

The Effect of Cryotherapy on Functional Balance of Shoulder Joint in Healthy Individuals

“…Literatürdeki çalışmalara bakıldığında, kriyoterapi uygulamasının tüm vücut veya lokal olarak uygulandığı gözlemlenmiştir. 2,22,23 Tüm vücut kriyoterapi uygulaması ile ilgili bir çalışmada fiziksel olarak aktif bireylerde kriyoterapi (3 dk boyunca -110°C sıcaklıkta sıvı azottan soğuk hava üretilmesi) ile kas yorgunluğu sonrası toparlanmaya bakılmıştır. 22 Başka bir çalışmada ise profesyonel futbolcularda tekrarlı sprint egzersizi sonrası tüm vücut kriyoterapinin (30 sn-60°C, 120 sn-135°C sıvı nitrojen bölmeleri) fizyolojik, performans ve algısal etkileri incelenmiştir.…”

Üst ekstremite için kriyoterapinin akut etkisinin değerlendirildiği çalışmalarda propriyosepsiyon, kas kuvveti ve atış doğruluğu incelenmiştir.…”
