This study aimed to analyze the effects of match congestion in a short period on isometric hamstring strength and hip/ankle range of motion in female field hockey players. Fourteen professional female field hockey players (age: 20.0 ± 5.4 years) played two consecutive hockey matches in 24 h and maximal isometric hamstring strength and hip and ankle range of motion were obtained before and after the first match, after the second match, and 48 h after the second match. Furthermore, locomotion patterns and ratings of perceived exertion were recorded during hockey competitions. Isometric knee flexion strength showed significantly higher values 48 h after the second match for the non-dominant limb (p ≤ 0.005, ηp2 = 0.19), while no differences were reported in the dominant limb (p = 0.370, ηp2 = 0.05). In addition, no differences were reported in the range-of-motion (ROM) variables such as the straight leg raise test or ankle dorsiflexion test (p = 0.075–0.217, ηp2 = 0.01–0.03). The countermovement jump height steadily increased over the matches except between post-match 2 and 48 h after post-match 2 (p < 0.001, η2 = 0.382). Two consecutive official league field hockey matches played within 24 h did not have a negative effect on lower-limb risk factors (strength, hip and ankle ranges of motion, and ratings of perceived exertion) in female field hockey players directly, but they improved 48 h after the matches. This could indicate that 48 h recovery period following matches might be ideal for female field hockey players.

“…The reduction in CMJ performance by the late phase indicates the players were in a compromised neuromuscular state for significant periods of the competitive season. Decreases in CMJ performance have been observed in athletes at the late stages of a season over shorter competition periods in collegiate ice hockey (18 weeks) (31) and collegiate soccer (11 weeks) (22,31). The findings of the current investigation correspond with previous studies, although in a professional cohort over a longer competition period (30 weeks).…”

Gannon, EA, Higham, DG, Gardner, BW, Nan, N, Zhao, J, and Bisson, LJ. Changes in neuromuscular status across a season of professional men’s ice hockey. J Strength Cond Res 35(5): 1338–1344, 2021—To quantify changes in neuromuscular function over a full professional men's ice hockey season, 27 players (n = 18 forwards and 9 defensemen) performed 3 countermovement jumps (CMJ) each week over 30 sessions separated into 4 phases: preseason, early-season, midseason, and late-season. Outcome variables represented jump performance (jump height), kinematics (mean velocity and peak velocity), and movement strategy (countermovement depth). Mixed models characterized relationships between positional group, season phase, and CMJ outcomes. Statistical significance was set at p ≤ 0.05. Concentric peak velocity (p = 0.02), jump height (p = 0.001), and countermovement depth (p < 0.001) displayed a significant reduction across the season. Peak velocity was lower during the early-season than the preseason (−0.10 ± 0.06 m·s−1, mean change ± 95% confidence limit, p = 0.05). Countermovement depth was reduced during the early-season (−0.06 ± 0.03 m, p = 0.02), midseason (−0.10 ± 0.04 m, p = 0.002), and late-season (−0.15 ± 0.04 m, p < 0.001) relative to the preseason. Reductions in CMJ variables from preseason to in-season ranged from trivial to large. Changes in countermovement depth differed for forwards and defensemen by the season phase (p = 0.04). A professional ice hockey season decreases CMJ performance, with the effects of fatigue most prominent during the late-season phase. Countermovement depth was most sensitive to fatigue and differentiated positional-group responses. Frequent CMJ testing is useful for identifying the neuromuscular status of team-sport athletes relative to season-specific phases. Fatigue monitoring should incorporate movement-strategy variables alongside traditional measures of performance and kinematics.

Determining performance indicators within team sports is considerably important as it facilitates the underlying training methodologies of sports performance. The value of understanding individual contribution and the relevant physical factors is of importance when structuring appropriate strength and conditioning training. Therefore, the aim of this study was to analyse the relationships between physical performance and game performance, as well as examining the relationships of physical performance and game performance dependent on competition level. This research project was a case study conducted with a team’s game performance measured across a full season. Twelve elite adolescent male ice hockey players (17.92 ± 0.9 years, 185 ± 8.45 cm, 83.17 ± 8.61 kg) participated in the study after giving informed consent. Physical performance was measured using four tests (horizontal jump, single-leg lateral jump, 15-meter sprint, corner S test), while game performance was calculated through the statistical equation Point Shares. Statistical significance was set at p ≤ 0.05. Physical performance did not depict any strong indications of overall game performance. Instead, results illustrated an inverse relationship between plyometric performance and offensive point shares. However, on-ice agility may be a relevant indicator of game performance dependent on competition level for individuals and sub-groups. Thus, the findings suggest that explaining individual performance within team sports is a highly complex issue that needs further investigation.
