Abstract
0126 Hydrotherapy (HYDRO), or the alternating use of hot and cold tubs (“contrast baths”), is frequently used by athletes in an attempt to speed recovery from intense exercise. HYDRO is purported to induce “vascular pumping” of peripheral blood vessels, promote the flow of nutrients to exercised muscles and accelerate the removal of “waste products.” Despite its popularity, few data are available to validate the proposed benefits of this intervention. PURPOSE: We examined the effect of HYDRO during recovery from daily high-intensity interval training (HIT) on physical performance and related psychological variables. METHODS: Twelve active men (25–35 yrs; VO2peak = 46±3 ml·kg−1·min−1) performed 5 consecutive days of HIT (4–6 bouts × 30 sec 'all out' Wingate Tests, with 4-min recovery). Following each HIT session, subjects either rested for 20 min (Control; CON, n = 6) or completed a HYDRO protocol (n = 6) of equivalent duration that consisted of alternating cold (10°C) and hot (40°C) tubs using a 4 × 2:3 min ratio. Peak (Wmax) and mean (Wmean) power during a 30-s Wingate test, VO2peak and time to complete a 250 kJ Time Trial (TT) were assessed before and 2–3 day following HIT. A profile of Mood States (POMS) and questionnaires designed to assess exercise preparedness were also completed daily. RESULTS: Wmax increased by ∼9% after SIT (main effect, P<0.05), but there was no difference between groups (HYDRO: Post: 1310±110 vs Pre: 1215±211; CON: Post: 1343±132 vs Pre: 1220±181 W, means±SD). TT performance also improved after HIT (main effect, P<0.05) with no difference between groups (HYDRO: Post: 15.8±1.5 vs Pre: 16.7±1.7; CON: Post: 18.1± vs Pre: 18.8±3.0 min). Wmean and VO2peak were unchanged after HIT. There were no differences in POMS subscale scores, however the HYDRO group reported feeling more revitalized after each treatment session and greater preparedness for subsequent exercise (P<0.05). CONCLUSION: 5 d of HIT (∼15 min total exercise time) increased peak anaerobic power and decreased the time required to complete a defined bout of work. HYDRO created the perception that subjects were better prepared for exercise, but did not further enhance performance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
