“…Interestingly, despite the failure rates and high numbers of females in the military who could not perform the leg tuck [ 4 , 5 ], the greatest magnitude of difference was not observed for this test. Rather, it was for the BOMBT, which assessed combined upper and lower body power and coordination [ 45 , 46 ]. Fitness tests and occupational job tasks that require maximal power tend to be challenging for females when compared to males [ 54 , 57 , 58 ].…”

The leg tuck was replaced by the plank in the Army Combat Fitness Test, in part because it was felt it discriminated against women. There is limited leg tuck research, including between-sex comparisons and relationships with other fitness tests. This study investigated the leg tuck in a firefighter trainee population (274 males, 31 females). Archival fitness test data included: Illinois agility test (IAT); push-ups; pull-ups; leg tucks; multistage fitness test; 4.54 kg backwards overhead medicine ball throw (BOMBT); 10-repetition maximum deadlift; and 18 kg kettlebell farmer’s carry over a 91.44 m course. Independent samples t-tests (p < 0.05) and effect sizes (d) compared the sexes. Partial correlations and stepwise regression (controlling for sex; p < 0.05) calculated relationships between the leg tuck with the other tests. Male trainees outperformed females in all tests (p ≤ 0.003). The largest difference was for the BOMBT (d = 2.59) not the leg tuck (d = 1.28). The strongest leg tuck relationships were with pull-ups (r = 0.790) and push-ups (r = 0.553). Sex, pull-ups, and push-ups predicted the leg tuck (r2 = 0.674). Approximately 80% of the females could complete one leg tuck, although female personnel may require specific strength and power training. Pulling strength may be a determining factor in leg tuck performance, which is likely not indicated by the plank.

“…The BOMBT with a 4.54 kg (10 lbs) medicine ball was used to assess combined upper and lower body power and coordination [ 45 , 46 ]. The trainee stood with their back to the throwing area, with their feet shoulder-width apart and heels on the start line.…”

“…Exclusion criteria included adolescent age and pooled data for players of several sports. The search yielded 24 observational studies: 12 of male (Gladden & Colacino, 1978; Viitasalo, 1982; Lee et al, 1989; Smith et al, 1992; Stockbrugger & Haennel, 2003; Kollias et al, 2004; Forthomme et al, 2005; Hertogh et al, 2005; de Ruiter et al, 2007; Laffaye et al, 2007; Sheppard et al, 2007a, b, 2008), 10 of female (Gladden & Colacino, 1978; Spence et al, 1980; Fleck et al, 1985; Marey et al, 1991; Hakkinen, 1993; Ferris et al, 1995; Barnes et al, 2007; Nesser & Demchak, 2007; Stech & Smulsky, 2007; Amasay, 2008), and two of male and female (Coutts, 1982; Lawson et al, 2006) players. In addition, eight experimental studies were found: four of male (Newton et al, 1999; Maffiuletti et al, 2002; Saez Saez de Villarreal et al, 2007; Pereira et al, 2008) and four of female (Smith et al, 1987; Fry et al, 1991; Newton et al, 2006; Marques et al, 2008) players.…”

The main purpose of this article was to review a series of studies (n=32; 24 observational and eight experimental) examining vertical jump (VJ) performances in female and male volleyball players. The main findings of this review are (a) players of better performing teams have higher VJ values; (b) strength and conditioning programs that emphasize plyometric training can increase VJ performance; and (c) it is important to continue conditioning sessions throughout the season in order to maintain VJ performance. Three research limitations associated with the testing protocols and the strength and conditioning programs used in the studies were outlined: (a) the use of multiple testing protocols; (b) lack of experimental studies; and (c) lack of data on the effect of VJ performance on achieving success in actual games. Four recommendations for volleyball and strength and conditioning coaches were given: (a) Plyometric training should be included in the annual training program; (b) Interruptions in the conditioning program during the season should be avoided; (c) Overtraining during the pre-season should be avoided; and (d) VJ performance should be tested throughout the entire season.

Army Combat Fitness Test Relationships to Tactical Foot March Performance in Reserve Officers’ Training Corps Cadets

The Army Combat Fitness Test (ACFT), consisting of deadlift, standing power throw, hand release push-up, sprint-drag-carry, leg tuck or plank, and 2-mile run, is the United States Army’s new fitness test. The ACFT is designed to measure multiple fitness components required to perform combat tasks. One critical task is the tactical foot march (TFM), where soldiers cover long distances while carrying loads comprised of mission-essential equipment. As the ACFT is meant to predict soldier task performance, determining the relationships between the ACFT and the TFM is important. Data from 29 cadets (♂ = 20, ♀ = 9) from one university Reserve Officers’ Training Corps program were analyzed. The ACFT was recorded in raw and scaled scores. The TFM was performed over 6.44 km, with time recorded. Cadets carried a 15.88-kg rucksack, fighting load carrier, 3-L hydration pack, and replica M4 carbine. Independent samples t-tests evaluated ACFT and TFM between-sex differences. Partial correlations, controlling for sex, determined ACFT event and TFM relationships. Male cadets outperformed females in all ACFT tasks (p ≤ 0.039), except the push-up. ACFT total score, leg tuck, 2-mile run, and sprint-drag-carry showed large correlations with the TFM (r = ±0.463–0.531, p ≤ 0.026). Aerobic and anaerobic capacity and upper body/trunk strength were important fitness components for cadet TFM performance.
