Massage Versus Cold Water Immersion for Fatigue-induced Biomechanical Alterations

The optimization of recovery to alleviate the effects of fatigue in athletes can provide valuable performance advantage. However, despite the growing body of literature regarding effects of different interventions in fatigue, there is still lack of clarity regarding the efficacy of interventions on running economy and, particularly, fatigue-induced biomechanical alterations. Therefore, the aim of this study was to compare the effects of massage and cold water immersion for enhancing recovery and alleviating fatigue after an exhausting training session. We hypothesized that both massage and cold water immersion would enhance biomechanical parameters compared with a control condition and hence would improve subsequent running economy.

About this study

In this randomized controlled all the subjects (n=48) will performed the same protocol. The protocol will begin with a exhausting training session (20-min warm-up consisted of 15-min of continuous self-paced running followed by 5-min of fast-finish progression runs increasing speeds (from approximately 60% to 80% of maximal heart rate, participant controlled), 10 x 500 m sprints at 90% of maximal heart rate with a 2-min rest period between bouts and a recovery phase consisting of 10-min of slow jogging). Twenty-four hours after this exhausting training, subjects will perform an incremental running test on a treadmill (Pre-intervention test) where subjects will start at 12 km/h for 6 min after which speed will be increased by 2 km/h every 6 min until a 16 km/h trial is completed. At the end of each stage, participants will rate their perceived exertion using the 10-point Modified Borg rating of perceived exertion scale (RPE scale). One hour after this test, in one protocol subjects will receive the massage intervention, (Massage group); other group will receive a cold water immersion intervention (Cold water immersion group); in the other group (Control group) participants will rest passively in a sitting position for 30-min period. To evaluate the relevance of the changes induced by the interventions (massage, cold water immersion, passive rest) subjects will repeat the treadmill test 48 hours after the first test (72 hours after the exhaustive training).

Treatment and study plan

Massage

Other

The intervention will be applied to both legs to a constant distal to proximal stroking rhythm. Firstly, participants will be lying in a prone position for 22 min: 1 min on the sole of the foot, 1 min on the Achilles tendon, 1 min on the soleus muscle, 3 min on the triceps muscle, 4 min on the hamstring muscles, 30 s tapotement from the sole of the foot to the hamstrings and 30 s superficial effleurage from the sole of the foot to the hamstrings. Then they will assume a supine position for 18 min: 1 min on the sole of the foot, 3 min on the tibialis anterior and peroneus lateralis muscles and 4 min in the quadriceps, adductors and lata muscles, 30 s tapotement from the sole of the foot to the hamstrings and 30 s superficial effleurage from the sole of the foot to the hamstrings.

Cold Water Immersion

Other

The cold water immersion group immersed their lower limbs (ensuring that the iliac crests were fully immersed) in an ice bath filled with cooled water for 10 min. The water was maintained at a mean temperature of 10 degrees (±0.5°) by the addition of ice.

Primary outcomes

  1. - CHANGE FROM BASELINE OXYGEN UPTAKE AT 48 HOURS AFTER THE TREATMENT

    Time frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Oxygen uptake (mL kg-1 min-1) will be assessed in an incremental running test on a treadmill (HP Cosmos pulsar, Nussdorf-Traunstein, Germany). Oxygen uptake will be recorded using a gas analyzer system (Esgostik Geratherm, Geschwenda, Germany).

  2. - CHANGE FROM BASELINE STRIDE LENGTH AT 48 HOURS AFTER THE TREATMENT.

    Time frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Stride length (cm) defined as the length the treadmill belt moves from toe-off to initial ground contact in successive steps, will be measured using an optical measurement system (Optojump-next, Microgate, Bolzano, Italy) placed at the treadmill belt level.

  3. - CHANGE FROM BASELINE STRIDE FREQUENCY AT 48 HOURS AFTER THE TREATMENT.

    Time frame: Time Frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Stride frequency, defined as the number of ground contact events per minute, will be measured using an optical measurement system (Optojump-next, Microgate, Bolzano, Italy) placed at the treadmill belt level.

  4. - CHANGE FROM BASELINE STRIDE ANGLE AT 48 HOURS AFTER THE TREATMENT.

    Time frame: Time Frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Stride angle (º), defined as the angle of the parable tangent derived from the theoretical arc traced by a foot during a stride and the ground, will be measured using an optical measurement system (Optojump-next, Microgate, Bolzano, Italy) placed at the treadmill belt level.

  5. - CHANGE FROM BASELINE GROUND CONTACT TIME AT 48 HOURS AFTER THE TREATMENT.

    Time frame: Time Frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Ground contact time (s), defined as the time from when the foot contacts the ground to when the toes left the ground and was determined by the disruption of the infrared gates, will be measured using an optical measurement system (Optojump-next, Microgate, Bolzano, Italy) placed at the treadmill belt level.

  6. - CHANGE FROM BASELINE SWING TIME AT 48 HOURS AFTER THE TREATMENT.

    Time frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    The swing time (ms) corresponds to the time from foot flat to initial take-off. Swing time will be measured using an optical measurement system (Optojump-next, Microgate, Bolzano, Italy) placed at the treadmill belt level.

  7. - CHANGE FROM BASELINE CONTACT PHASE AT 48 HOURS AFTER THE TREATMENT.

    Time frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Contact time (ms), defined as the percentage of the ground contact time at which the different sub-phases of stance phase occur, will be measured using an optical measurement system (Optojump-next, Microgate, Bolzano, Italy) placed at the treadmill belt level.

  8. - CHANGE FROM BASELINE RATING OF PERCEIVED EXERTION AT 48 HOURS AFTER THE TREATMENT

    Time frame: Participants will be assessed at baseline (24 hours after an exhaustive training session) and at 48 hours after the treatment.

    Modified Borg rating of perceived exertion scale (RPE scale) defined as a way of measuring physical activity intensity level, how hard you feel like your body is working. The Borg RPE scale is a numerical scale that ranges from 1 to 10, where 0 means "no exertion at all" and 10 means "maximal exertion."

    • Body height (cm) will be measured using a stadiometer (Año Sayol, Barcelona, Spain) following the guidelines outlined by the International Society for the Advancement of Kinanthropometry.

    Time frame: Participants will be assessed at baseline (24 hours after an exhaustive training session).

    • Body mass (kg) will be measured using a balance (Año Sayol, Barcelona, Spain) following the guidelines outlined by the International Society for the Advancement of Kinanthropometry.
