The influence of growth and training loads on injury risk in competitive trampoline gymnasts

Figures & data

Table 1. Participant characteristics

Participants		Age (yrs.)	Height (cm)*	Body mass (kg)*	% of adult height*	Growth spurt status
Male (n = 13)	10–19; 13.4 ± 2.5		141.4–183.9; 157.7 ± 13.7	32.70–76.7; 47.81 ± 15.11	80.0–101.6; † 89.4 ± 7.0	Pre = 6, Circa = 4, Post = 3
Female (n = 8)	10–17; 13.1 ± 2.0		147.9–163.2; 158.1 ± 5.13	36.75–60.15; 50.13 ± 8.77	87.7–99.5; 95.8 ± 3.9	Pre = 0, Circa = 3, Post = 5

Min-Max; Mean ± SD (Age, height, weight & percentage of adult height from data collected closest to competition). *Estimated for 3 (1 male, 2 female) gymnasts from data points taken before and after data collection period. †Percentage of adult height calculated for gymnast aged 19 from predicted height calculated at aged 17.9 years.

Table 2. Average weekly prevalence of an ‘all-complaints‘ injury

	All	Pre	Circa	Post
All complaints	30% (27 to 34%)	25% (2 to 48%)	38% (24 to 52%)	28% (17 to 39%)
All complaints that resulted in modification of training	10% (8 to 12%)	10% (−3 to 23%)	13% (4 to 21%)	6% (1 to 12%)

Average Weekly Prevalence (95 CI). Pre, Circa and Post growth-spurt status.
