Utilizing hand paddles throughout swimming is a typical follow within the sport. Though many swim coaches use hand paddles for coaching, do they contemplate how swimming hand paddle coaching influences swimming biomechanics? Using paddles throughout coaching doubtless will alter biomechanics, however how does the paddle dimension change biomechanics? Should not this be a consideration contemplating the arms produce roughly 85% of the propulsion in front-crawl stroke?
In a latest examine, twenty swimmers (10 males and 10 girls), members of the identical squad, participated on this examine. They have been matched in pairs in accordance with 50-m freestyle efficiency within the earlier season and gender, and have been randomly assigned to both management (CON, 22.4 ± 2.Three years; 70.5 ± 10.5 kg; 1.72 ± 0.08 m; hand space: 156 ± 20 cm2 ; short-course 50 m freestyle: 31.08 ± 4.73 s) or hand paddles (HPD, = 21.8 ± 1.9 years; 65.5 ± 12.Eight kg; 1.70 ± 0.11 m; hand space: 149 ± 25 cm2 ; short-course 50 m freestyle: 30.17 ± 4.63 s) teams.
After two introductory weeks (weeks 1 and a pair of) of low-to-moderate coaching periods (identical for each teams), the 6-week monitored coaching interval began. Throughout the first Four weeks (weeks 3–6), each teams carried out the identical in-water coaching (5 days per week, i.e., Mon–Fri, 1 coaching session/day, 10,758 ± 1,172 m/week, distance distribution throughout low, reasonable and high-intensity zones in accordance with the coach’s supposed prescription: 69 ± 6%, 22 ± 4% and eight ± 3%, respectively) and a further experimental dash coaching set, which consisted of 10 × 10 strokes (i.e., 5 full cycles) at maximal depth from a push-off begin, with 1-min relaxation. CON carried out the experimental set with out paddles, whereas HPD used commercially out there hand paddles (Stroke Maker, Professional Swim®).
A 2-week taper interval was performed within the weeks 7 and eight, when the dry-land coaching was ceased, and the in-water coaching quantity was progressively lowered (Week 7 = 7,300 m and Week 8 = 6,250 m) whereas depth was maintained.
Swimming Hand Paddle Coaching Does not Change Biomechanics
The outcomes demonstrated that this implement did not induce modifications in swimming efficiency, clear swimming velocity, stroke fee, stroke size and tethered pressure after a 4-week intervention interval.
Questions and Considerations
Clearly, doing 10 strokes is not the most typical type of coaching with hand paddles. Additionally, utilizing one kind of hand paddle dimension is not the widespread technique of hand paddle coaching. One other distinction is swimmers are usually not simply using hand paddles coaching for 4-weeks.
These outcomes are barely completely different than earlier research, because the researcher’s observe on this examine:
“[P]revious research investigated diﬀerent implements (elastic tube, bowl, parachute and push-oﬀ factors), coaching frequencies (Three to Four occasions per week), units (1 to three units per session) and durations (from Three to 12 weeks). All of them reported that the enhancements in aggressive performances have been higher within the intervention teams than within the management teams (Girold et al., 2006; Gourgoulis et al., 2019; Mavridis et al., 2006; Toussaint & Vervoorn, 1990), and this can be of nice sensible relevance. Whereas some supply of errors may be raised (e.g., organic maturity, unmatched variety of individuals within the teams, and adherence to the coaching programme), their outcomes point out that the in-water resistance coaching may be eﬀective to enhance swimming efficiency.”
Nonetheless, if a swimmer is using hand paddles for 4-weeks of dash swimming, then it’s unlikely to change your swimming biomechanics.
