Abstract

A new wheelchair tennis hand rim was developed, having a larger contact area and higher friction. How does this new hand rim compare to a regular hand rim regarding submaximal propulsion with a tennis racket during practice in novices? Twenty-four able-bodied novices (12 Regular Rim, 12 New Rim) completed a one-day experiment: pre-test, three practice-sessions and a post-test of 3 × 4 min each on a wheelchair ergometer (1.11 m/s, 7W). The New Rim group compared to the Regular Rim group, had a lower negative work per cycle (−0.83J vs. −2.06J, p = 0.01) at the post-test. There was a significantly larger increase in mechanical efficiency between the pre- and post-test in the New Rim group (2.3–3.4% vs. 2.1–2.5%, p = 0.02) compared to the Regular Rim group. The new rim led to a more ergonomic propulsion technique, with a reduction in negative power and higher mechanical efficiency between the pre- and post-test at submaximal propulsion.
