Respiratory Muscles Training Program for the Experimental Group
This novel respiratory muscle training program followed by the experimental group included a warm-up session, flexibility training, inspiratory and expiratory muscle strength training programs and warm-down sessions. The respiratory muscle training program was conducted for 7 days per week for 12 weeks.
Warm-Up session: Rowers followed a warm-up exercise session prior to performing the
respiratory muscle training program. This included 10 minutes of running with normal breathing with inspiration through the nose and expiration through mouth.
Flexibility Training
- Full body stretch and (Thomas et al., 2005).
- Lateral stretch (Thomas et al., 2005).
Respiratory Muscle Training
Inspiratory Muscle Training
(I) Diaphragmatic re-education(Porter, 2013)
(II) Profound (Deep) Inspiration(Porter, 2013)
(III) Inspiratory hiccups (Porter, 2013).
Expiratory muscle training
(I) Isometric Side Bridge (Thomas, et al., 2005).
(II) Curl-ups (Thomas et al., 2005).
Warm down session: After the respiratory muscle training program, the rowers followed a
warm-down session. This included 10 minutes of running with normal breathing while inspiring
through the nose and expiring through mouth.

General Exercise Program for the Control Group
The general exercise program followed by the control group consisted of a warm-up session
(similar to intervention group), flexibility training and strength training programs for non
respiratory muscles such as biceps, triceps, quadriceps and hamstring muscles. The control group
did not receive any intervention for respiratory muscle strength training. This was in addition to
the routine exercise schedule followed during the competition season. This training program was
conducted for 7 days per week for 12 weeks.
Warm-Up session
Rowers in the control group followed the same warm-up session which was followed by the
experimental group. This included 10 minutes of running with normal breathing, inspiration
through the nose and expiration through the mouth.
Flexibility Training
Flexibility training of the control group included the following:
(I) Biceps stretching : (Thomas et al., 2005).
(II) Triceps stretching: (Thomas et al., 2005).
Strength training
In the control group, strength training exercises were included as follows:
(I) Biceps curls : (Thomas, et al., 2005).
(II) Triceps curls: (Thomas et al., 2005).
(III) Hamstring curls : (Thomas et al., 2005).
(IV) Quadriceps strengthening (Straight Leg raises) : Thomas et al., 2005).
Warm down session: Rowers followed a warm down session after the general exercise program.
This included 10 minutes of running with normal breathing After the warm-down session, the
rowers were instructed to stretch all the major muscle groups (biceps, triceps, quadriceps and
hamstring) that were used during the exercise program for 20 to 30 seconds, 2 to 3 times
(Thomas et al., 2005).

The findings of this study suggest that the novel respiratory muscle training
program had some beneficial effects on selected ventilatory parameters and rowing
performance in professional Army rowers in Sri Lanka. Therefore, it can be concluded that
this novel RMT program would be beneficial in improving respiratory functions,
strengthening the respiratory muscles, improving aerobic fitness and sports performance of Sri
Lankan sportsmen.

In total, 20 male rowers between the ages of 20-35 years were selected from a total population
of 40 from the Sri Lanka Army rowing team using the random number generator. The age,
height and weight matched study population was divided into two groups: an experimental
group (n= 11) and a control group (n= 9).
日本語

Data collection was carried out at the General Sir John Kotelawala Defence University and the
Exercise and Sports Science laboratory, Department of Physiology, Faculty of Medicine,
University of Peradeniya. Prior to the commencement of the training program, baseline
measurements and tests namely lung volumes, flow rates and capacities, VO2 max, respiratory
muscle strength including maximal inspiratory (PImax) and maximal expiratory pressures
(PEmax), 2000m and 5000m rowing ergometer time trial were carried out on all 20 subjects
by the principal investigator.
