Ferland, PM and Comtois, AS. Classic powerlifting performance: A systematic review. J Strength Cond Res XX(X): 000–000, 2019—The purpose of this study was to review all scientific publications related to able-body drug-tested classic powerlifting performance since January 1, 2012, and to regroup them into a brief narrative review. Three electronic databases were systematically searched in August 2018 using the wildcard: powerlift*. A manual search was performed from the reference list of all retained articles. The search and selection strategy permitted to gather a total of 16 scientific articles published in peer-reviewed journals. Results show that practitioners should prioritize a low-bar squat and a wide grip bench press because they generally contribute to moving greater loads, bring more attention to preventing injuries, since a fair amount of powerlifters seem to train injured and prioritize a hypertrophy-power-strength model when prescribing 3 times a week daily undulating periodization on nonconsecutive days for squat and bench. Practitioners could also introduce respiratory muscle training, use daily 1 repetition maximum training combined with down sets on experienced athletes and use a rate of perceived exertion scale based on repetitions in reserve combined with an individual velocity profile when prescribing intensity. Before competition, powerlifters seem to taper in this order: the deadlift, the squat, and lastly the bench press. The Slingshot does help to move more weight because it helps to generate more inertia, but it also deactivates the triceps. Finally, the present work was limited by the present literature but could serve as a reference in the field of powerlifting. Further research should include more details about the circumstances under which they were conducted.

Ferland, PM and Comtois, AS. Athletic profile of alpine ski racers: a systematic review. J Strength Cond Res 32(12): 3591–3600, 2018—The purpose of this study was to review all anthropometric and physical test results performed on alpine ski racers that were published in the scientific literature to build an athletic profile specific to the skier's sex and level. Four electronic databases were systematically searched using the following key words: alpine, skiing, and physiology. The manual search was performed through the reference list of all suitable publications, the author's personal collection, and the proceedings of the International Congresses on Science and Skiing. The search and selection strategy permitted to gather data from 28 peer-reviewed publications that were collected on a total of 1,107 skiers coming from 11 different countries. Results of this study present the athletic profile and also review the different testing protocols. Findings show that men generally present higher test results than women and that higher-level ski racers generally present higher test results than lower-level ski racers. The present review should serve as guidelines for professionals working with alpine ski racers because most of the factors presented in the athletic profile have previously been shown to be related with performance. Further research should include more details on the testing protocols used, be directed toward female athletes, and present results from groups of athletes of the same sex and clearly identified as established at a certain level. These measures could help support further theoretical investigations.

Ferland, P-M, Marcotte-L'Heureux, V, Roy, P, Carey, V, Charron, J, Lagrange, S, Leone, M, and Comtois, AS. Maximal oxygen consumption requirements in professional North American ice hockey. J Strength Cond Res 35(4): 1586–1592, 2021—This study was designed to measure preseason on-ice relative V̇o 2max of professional ice-hockey players (n = 101 National Hockey League [NHL], 42 American Hockey League [AHL], 4 East Coast Hockey League [ECHL], and 15 Canadian Hockey League [CHL]) throughout 17 years and compare it between generations, league level, and position, and to verify if it was related to season and NHL career statistics. Relative V̇o 2max was measured on ice with a portable metabolic analyzer (K4b2, Cosmed, Rome) with full hockey equipment, except for the helmet with either the Skating Multistage Aerobic Test or the 30–15 intermittent ice test tests. Relative V̇o 2max results from both tests were compared between players of the same generation with an independent-samples T-test and were not significantly different. A one-way analysis of variance and post hoc pairwise tests were performed to detect significant differences between groups. Pearson correlations (two-tailed) were also performed between selected variables. All statistical significance was set at p < 0.05. Results show that there are no significant differences for relative V̇o 2max between generations (2001–2003 vs. 2006 vs. 2015–2017), league level (NHL vs. AHL vs. ECHL vs. CHL), and position (winger, center, and defense), other than the ECHL being lower. There are also no significant relationships between V̇o 2max values and hockey season and NHL career statistics. Thus, the results show that there is a minimal relative V̇o 2max requirement to play North American ice hockey at the elite level (55.9 ± 5.2 ml·kg−1·min−1; n = 162). Future research should be directed toward comparing V̇o 2max of elite and amateur ice-hockey players to confirm the minimal relative V̇o 2max requirement to play North American ice hockey at the elite level.
