Table 3:Physiological, strength and performance parameters measured pre- and post-training for male and female swimmers.
Variable | Pre | Post | Percentage change (%) | Effect size |
---|---|---|---|---|
Flexibility (SRT) (cm) | 17.9 ± 7.6 | 19.3 ± 7.3 | 7.4 (↑) | -0.25 |
CMJ (cm) | 25.2 ± 4.2 | 29.4 ± 5.2* | 16.8 (↑) | -1.26 |
HG strength right (kg) | 22.9 ± 7.9 | 24.1 ± 6.3 | 5.2 (↑) | -0.24 |
HG strength left (kg) | 22.5 ± 7.0 | 22.4 ± 4.3 | 0.5 (↓) | 0.03 |
Back and leg strength (kg) | 71.1 ± 15.7 | 90.9 ± 14.7* | 28.0 (↑) | -1.85 |
Push ups (number in 60 s) | 30.7 ± 9.1 | 41.9 ± 7.9* | 36.6 (↑) | -1.86 |
Sit ups (number in 60 s) | 30.8 ± 6.2 | 35.0 ± 6.1 | 13.7 (↑) | -0.97 |
VO2peak (ml.kg.min-1) | 43.5 ± 5.9 | 43.9 ± 9.3 | 1.0 (↑) | -0.08 |
Time to 5.5 m (s) | 2.1 ± 0.2 | 2.4 ± 0.3* | 14.6 (↑)¥ | -1.70 |
100 m frontcrawl (s) | 69.1 ± 6.5 | 68.4 ± 6.0 | 1.1 (↓) | 0.26 |
N = 9 All values are means ( ± SD). *indicates significant differences between pre and post (p < 0.05); ¥indicates a performance decrement. (↑) indicates a percentage increase; (↓) indicates a percentage decrease; Flexibility (SRT) = hamstring and lower back flexibility; CMJ = countermovement jump; HG = handgrip. A negative effect size indicates an increase in score from pre- to post-training.
