- Description: The purpose of this investigation was to determine whether weightlifting actions are a viable method for improving athletic performance among weaker, inexperienced lifters when compared with individuals with a greater power clean (PC) result, and hence weightlifting ability and experience. Two groups of males with distinctly different PC performances (higher performance [HP]: N = 8; body mass [BM] = 78.1 +/- 4.0 kg; 1 repetition maximum [1RM] PC = 1.08 +/- 0.09 kg.BM-1; lower performance [LP]: N = 8; BM = 82.6 +/- 14.0 kg; 1RM PC = 0.78 +/- 0.1 kg.BM-1) and resistance training age (HP: resistance training experience = 3.5 +/- 1.2 years; LP: resistance training experience = 1.44 +/- 1.50 years) undertook 10 weeks of training involving weightlifting derivatives, in addition to supplemental ballistic and plyometric exercises. Testing of athletic performance (represented by measures derived from the countermovement jump) occurred at baseline, after 5 weeks of training, and after 10 weeks of training. Both groups significantly improved across the majority of outcome variables after training (Hedges' g = 0.98-2.55, p <= 0.01-0.05). Only the HP participants experienced significant changes at midtest (g = 0.99-1.27, p <= 0.01-0.05), whereas no significant changes were revealed between midtest and posttest in this group. In contrast to this, the LP participants displayed a significant improvement in relative impulse (g = 1.39, p < 0.01) and rate of force development (g = 1.91, p < 0.01) during this final period (p < 0.01). As weaker, inexperienced lifters underwent a significant and meaningful enhancement in maximal neuromuscular measures after weightlifting derivative-focused training, practitioners should consider early implementation of such exercises. However, it is important for coaches to note that a delayed training effect might be present in weaker, less experienced lifters.

- Description: Aspiring and established strength and conditioning professionals are increasingly seeking opportunities to further their knowledge to gain a competitive advantage within the highly competitive profession. Postgraduate degree programs in the discipline are therefore becoming a popular option for academic institutions to meet the demands of the workforce and marketplace. The purpose of this article is to bring together experienced practitioners and applied academics to offer considerations for the prospective strength and conditioning postgraduate student. Furthermore, this piece can be considered by academics that are responsible for the development of such programs. Future students are encouraged to reflect on their strengths and weaknesses, current and intended career trajectory, and work-life circumstances. Students' needs and wants, industry demands, and teaching and learning processes must be well understood by academics responsible for developing these programs. Finally, factors such as coursework and research content, authentic teaching and learning tasks, professional practice, and accreditation requirements represent key considerations of a successful postgraduate strength and conditioning program.
