Inspiratory Muscle Training Plus Cold Water Immersion After Muscle-Damaging Exercise

2026年11月3日 更新者：Mete Berk Demiryol、University of Gaziantep

The Combined Effect of Cold Water Immersion and Inspiratory Muscle Training on the Recovery From Exercise-Induced Muscle Damage and Physical Performance: A Randomized, Placebo-Controlled Crossover Study

The purpose of this study is to examine, using a placebo-controlled design, the additional effect of inspiratory muscle training (IMT) added to cold water immersion (CWI) on recovery and muscle performance following exercise-induced muscle damage (EIMD), and to determine whether this effect varies depending on the timing of the intervention. The study will include 12 healthy male athletes aged 18-22 who have been licensed for at least 4 years and are actively involved in sports. Each participant will undergo four different interventions in a randomized order determined by the Williams balanced sequence following muscle damage induced by eccentric exercise on an isokinetic dynamometer: CWI + placebo IMT immediately after exercise, IMT + CWI immediately after exercise, IMT + CWI 24 hours after exercise, and a control condition with no recovery intervention. The sessions will be conducted in weekly cycles with 7-day intervals, alternating between the dominant and non-dominant legs; thus, there will be a 14-day interval between two loading sessions for the same leg. All measurements will be taken during the week. Muscle strength will be assessed using an isokinetic dynamometer; markers of muscle damage (CK, myoglobin, LDH) will be measured via blood samples; and muscle pain will be evaluated using the Visual Analog Scale (VAS) before each exercise session and 48 hours after exercise.

武器和干预

参与者组/臂
干预/治疗
假比较器：CWI + placebo IMT

Device: Placebo IMT - 2 × 30 breaths at 15% of MIP using POWERbreathe (1 min between sets), immediately following the short test after EIMD. Other: Immersion in cold water - immediately following the placebo IMT, in 10-12 °C water, up to waist level or with legs fully submerged, for 10-15 minutes.
其他：Cold Water Immersion

Immersion up to the waist in water at 13-15 °C for 13-15 minutes in a portable ice bath; water temperature is monitored with a thermometer and maintained by adding ice.

其他：Sham Inspiratory Muscle Training

Same device, position and volume as inspiratory muscle training (two sets of 30 breaths, 1 minute rest), but at 15% of maximal inspiratory pressure, a load considered below the training threshold. Followed immediately by cold water immersion.
实验性的：IMT + CWI (immediately)

Other: Inspiratory muscle training + cold water immersion. Immediately following the short test after EIMD, 2 × 30 breaths at 40% of MIP using POWERbreathe (1 min rest between sets), followed by CWI.
其他：Cold Water Immersion

Immersion up to the waist in water at 13-15 °C for 13-15 minutes in a portable ice bath; water temperature is monitored with a thermometer and maintained by adding ice.

其他：Inspiratory Muscle Training

Two sets of 30 breaths at 40% of maximal inspiratory pressure with 1 minute rest between sets, using a POWERbreathe device; oxygen saturation is monitored by pulse oximetry. Followed immediately by cold water immersion.
实验性的：IMT + CWI (at 24 hours)

Other: Inspiratory muscle training + cold water immersion. The same IMT and CWI protocol is administered 24 hours after EIMD; the 48-hour measurement is taken relative to EIMD (24 hours after the intervention).
其他：Cold Water Immersion

Immersion up to the waist in water at 13-15 °C for 13-15 minutes in a portable ice bath; water temperature is monitored with a thermometer and maintained by adding ice.

其他：Inspiratory Muscle Training

Two sets of 30 breaths at 40% of maximal inspiratory pressure with 1 minute rest between sets, using a POWERbreathe device; oxygen saturation is monitored by pulse oximetry. Followed immediately by cold water immersion.
无干预：Control

No recovery procedure is performed after the EIMD protocol; only measurements are taken.
