Brief Summary

Swimming is a sport that includes different styles and distances, which can expose the athlete to different stressors that can affect performance and generate conditions such as overtraining. This is due to the lack of integration of systematic recovery periods during training programs. A very used recuperative feature in swimming is massage. Recent studies have shown that the application of short duration is sufficient to obtain the desired effects and it is possible that its application systematized over a period of time may have greater effects on performance. The aims of this study were to evaluate the effects of deep and superficial massage on clinical, functional and performance issues; to identify its short-term effects on clinical and functional variables and to investigate the association between training load and the swimmer's perceptions.

Study Arms (3)

Deep Massage

EXPERIMENTAL

The deep massage was performed three times during a training week, after a physical training and before the swimming training

Other: Deep Massage

Superficial Massage

ACTIVE COMPARATOR

The superficial massage was performed three times during a training week, after a physical training and before the swimming training

Other: Superficial Massage

Control

NO INTERVENTION

The control group kept their normal routine of training. Immediately after the physical training the athletes were instructed to wait for 12 minutes (passive recovery) until the beginning of the swim training.

Interventions

The deep massage group received 12 minutes of massage on the legs, arms and the back with three different sliding pressures.

Deep Massage

The superficial massage group received 12 minutes of only one sliding pressure performed on the legs, arms and the back.

Superficial Massage

Model Details: For the control group, immediately after the resistance training the athletes were instructed to wait for 12 minutes until the beginning of the swimming training. The deep massage group received 12 minutes of massage on the legs, arms and the back with three different sliding pressures. The superficial massage group received superficial massage on the same sites than the intervention group. The three conditions were performed after a resistance training and before a swimming training.
