Lower Body Strength-Training Versus Proprioceptive Exercises on Vertical Jump Capacity: A Feasibility Study

Volleyball is a sport comprised of multiple explosive efforts and multidirectional change of direction speed (CODS) actions. Since strength underpins both of these abilities, it is important to explore the relationship between these variables in order to develop strength and conditioning programs to optimize performance. The purpose of this study is to determine if a relationship exists between absolute and relative strength and measures of power and CODS in collegiate volleyball players. Archived testing data from ten (n = 10, age: 19.1 ± 1.2 yrs, Ht: 173.1 ± 6.64 cm, Wt: 67 ± 7.04 kg) female DII collegiate volleyball players were analyzed. These data included: block vertical jump (Block VJ), approach vertical jump (Approach VJ), a repeat jump test (i.e., four consecutive VJs), modified T-test, 5-0-5 agility test, a single leg triple hop test, and a 1-3RM deadlift. Significant large correlations were observed between relative strength and the repeat jump test, modified T-test, and 5-0-5 agility test. Significant correlations were also observed between absolute strength and the modified T-test. These results indicate that strength and conditioning professionals should emphasize the development of both absolute and relative lower-body strength to improve measures of power and agility in collegiate volleyball players.

Lower Body Strength

The primary purpose of this investigation was to provide a descriptive analysis of lower-body strength and vertical jump performance in overweight male (n = 8) and female (n = 13) adolescents. Maximal strength was tested in the leg press and isometric squat. Kinetic and kinematic variables were assessed in vertical jumps at various loads. When compared with females, males demonstrated significantly greater (p ≤ .05) absolute maximal strength in the leg press. However, when maximal strength was expressed relative to body mass, no significant difference was observed. There were no significant differences between males and females in vertical jump performance at body mass.

Division Ii

The purpose of this study was to investigate the relationships between absolute and relative lower-body strength on predictors of athletic performance among Division II collegiate women’s soccer players. Archived pre-season testing data for seventeen (n = 17) female National Collegiate Athletics Association (NCAA) Division II soccer players were analyzed, including: vertical jump, 3RM back squat, 505-agility, modified T-test, 10 m and 30 m sprint, and 20 m multistage fitness test (20 m MSFT). Relative strength was calculated based on the estimated 1RM back squat divided by the athlete’s body mass. Significant correlations were discovered between absolute lower-body strength and 505-agility (Right: r = −0.51, p < 0.05; Left: r = −0.59, p < 0.05), modified T-test (r = −0.55, p < 0.05), 10 m and 30 m (r = −0.59, p < 0.05; r = −0.54, p < 0.05), and sprint performance. Relative lower-body strength showed significant correlations with vertical jump (r = 0.54, p < 0.05), 505-agility (Right: r = −0.58, p < 0.05; Left: r = −0.67, p < 0.01), modified T-test (r = −0.75, p < 0.01), 10 m and 30 m (r = −0.59 p < 0.05; r = −0.67, p < 0.01), and the 20 m MSFT (r = 0.58, p < 0.05). These results indicate that strength and conditioning coaches should emphasize the development of absolute and relative lower-body strength with their players to improve power, agility, and speed performance.

Physical fitness is an important aspect of physical health and wellbeing. The aim of this study was to investigate the effects of 11-weeks of formal strength and conditioning training conducted during fire academy training on the physical fitness characteristics of firefighter trainees. Archived physical fitness data for 23 male fire academy trainees (age: 27.6 ± 4.3 y; height: 178.5 ± 6.9 cm; body mass [BM]: 83.9 ± 1.8 kg; BM index [BMI]: 26.8 ± 2.8 kg/m2) were analyzed for this study. These data included vertical jump height, maximum pull-up repetitions, hand grip strength, lower-body strength (3RM Hexbar) and aerobic fitness. Trainees performed three sessions per week (two resistance training sessions and one aerobic conditioning session) in addition to fire academy training. A repeated measures ANOVA revealed significant (p < 0.05) pre-post decreases in BM and BMI and significant increases in upper- and lower-body strength, and aerobic fitness. Strength and conditioning programs are beneficial for improving firefighter trainees’ physical fitness even when run concurrently with fire academy training and with limited space and equipment. This increased fitness may aid in mitigating known occupational injury risks to this population and improve task performance.

The purpose of the study was to investigate the effect of seven weeks inter-repetition rest vs. traditional strength training on lower body strength, rate of force development (RFD), and vastus lateralis (VL) muscle architecture. Sixteen male participants were assigned into two groups: the inter-repetition rest (IRRG) and the traditional (TG) group. Both groups performed the leg press exercise with four sets of six maximum repetitions (RM) for two training sessions per week. IRRG added a 20 s inter-repetition rest period between single repetitions. Before and after the training period, 1-RM in leg press, isometric leg press RFD, and peak force (PF), VL muscle architecture, vastus intermedius (VI) thickness, and quadriceps’ cross sectional area (CSA) with ultrasonography, were measured. Two way ANOVA for repeated measures was used for statistics. One-RM strength increased similarly for both groups (p < 0.05), while percentage increases in RFD were greater for IRRG compared to TG (p < 0.05). Isometric PF was increased similarly for both groups (p < 0.05). VL and VI thickness as well as CSA of the quadriceps increased similarly in both groups, while VL fascicle length increased more following IRRG compared to TG (IRRG: 4.8 ± 6.1% vs. TG: −3.9 ± 5.4%, p = 0.001). These results suggest that 20 s inter-repetition rest during strength training may effectively increase lower body explosive strength and muscle fascicle length without compromising muscle hypertrophy.

Post Shift

Based on current law enforcement officer (LEO) duties, musculoskeletal injury risk is elevated due to the unpredictable nature of physically demanding tasks. The purpose of this 4-week study was to determine the effectiveness of a 15-min post-shift standardized occupational specific training program. The standardized program was designed to improve lower-body strength and speed to aid physically demanding task performance. Seven male LEOs completed the program after their 12-h shift. Subjects were required to use the department fitness center to perform the 15-min standardized program consisting of a dynamic warm-up, 4 sets of 3 repetitions on hex-bar deadlift and four 20-m sprints. Two minutes of rest was required between each set of 3 repetitions on hex-bar deadlift and 1 min of rest between each 20-m sprint. A dependent T-test was used between pre-test and post-test scores for hex-bar deadlift (HBD) and sprint. Data revealed significant improvements in relative lower-body strength with HBD (p ≤ 0.001). However, insignificant results were demonstrated with the 20-m sprint (p ≤ 0.262). In conclusion, a 15-min post-shift workout can improve lower-body strength as measured by the hex-bar deadlift. However, data indicated running speed may require a different training approach to improve the 20-m sprint.
