Brief Summary

This study aims to investigate the acute effects of PNF modified sleeper stretches and percussive massage treatment on shoulder rotation movements and attack speed in female volleyball players and compare these applications.

Conditions

Sports Physical Therapy

Outcome Measures

Primary Outcomes (1)

• Shoulder internal rotation range of motion

  Change of shoulder internal rotation range of motion (with a digital inclinometer)

  baseline measurements, 5 minutes and 30 minutes

Secondary Outcomes (1)

• Attack Speed

  baseline measurements, 5 minutes and 30 minutes

Study Arms (2)

Proprioceptive Neuromuscular Facilitation Stretching

EXPERIMENTAL

Proprioceptive Neuromuscular Facilitation Stretching Group participants will undergo one session of PNF posterior shoulder stretching exercise in the modified sleeper position.

Behavioral: The Proprioceptive Neuromuscular Facilitation Stretching

The Percussive Massage Treatment

EXPERIMENTAL

The Percussive Massage Treatment Group participants will receive a 5-minute massage on the posterior deltoid area.

Device: The Percussive Massage Treatment

Interventions

The Percussive Massage Treatment DEVICE

In the group where regional vibration is applied, the Hypervolt™ vibrating massage device (HYPERICE Inc, US) will be used. This device is a vibration device with five different speed settings, vibrating at 3,200 percussions per minute (HYPERICE Inc. 'Hypervolt' device. Retrieved from https://hyperice.com/hypervolt-bluetooth, Accessed on: 08.12.2021). The device offers five different head attachment options. For this study, the ball attachment option will be selected as it is the least aggressive option, and the vibration from the device will be applied to the relevant muscle body (Kayoda, 2019). For facilitatory effect, the application will be performed on the posterior deltoid for 5 minutes at a low frequency.

The Percussive Massage Treatment

The Proprioceptive Neuromuscular Facilitation Stretching BEHAVIORAL

Among the PNF stretching techniques, the muscle-relaxation technique will be applied. The athlete will be positioned in a side-lying posture on the treatment table with the dominant shoulder in the modified sleeper position, ensuring stabilization of the scapula on the table. The other arm will be positioned in extension along the body with the palm facing upwards. The participant will be instructed to actively bring the arm of the lower limb to the physiological barrier of internal rotation. At this point, they will be asked to perform maximum isometric contraction in external rotation for 7 seconds. After the isometric contraction, the muscle will be relaxed, and active-assisted stretching will be applied in internal rotation for 15 seconds. A 5-second rest will be provided between repetitions, and the exercise will consist of 5 repetitions.
