BackgroundBiomechanics is crucial in enhancing sports performance and preventing injury. Traditionally, discrete point analysis is used to analyze important kinetic and kinematic data points, reducing continuous data to a single point. One-dimensional Statistical Parametric Mapping (spm1d) offers a more comprehensive approach by assessing entire movement curves instead of isolated peak values. Nevertheless, spm1d is still underutilized in various sports and sports-related injuries.PurposeTo summarize the existing literature on the application of spm1d in sports biomechanics, including the kinetics and kinematics of the hip, knee, and ankle joints, as well as to identify gaps in the literature that may require further research.MethodsA scoping review was conducted, searching PubMed, Embase, Web of Science, and ProQuest databases. English peer-reviewed studies using SPM to assess lower limb kinetics or kinematics in different sports or sports-related injuries were included. In contrast, reviews, meta-analyses, conference abstracts, grey literature, and studies focusing on non-kinetic or kinematic outcomes were excluded.ResultsThe review yielded 129 papers, with an increased number of studies published in the last three years. Of these studies, 81 examined healthy individuals (63%), and 48 focused on injured populations (37%). Running (n=28), cutting (n=21), and jumping/landing (n=14) were the most common activities. The most prevalent sport-related injuries examined were anterior cruciate ligament rupture (n=21), chronic ankle instability (n=16), and hip-related pain (n=9). Research gaps include the underrepresentation of common sports and movements, small sample size, lack of studies in non-laboratory settings and varied active age groups, and absence of evaluations on the effects of protective sports gear other than shoes.ConclusionThe application of spm1d in sports biomechanics demonstrates diverse uses in sports performance, injury reduction, and rehabilitation. While spm1d shows promise in improving our understanding of sports biomechanics, there are still significant gaps in the literature that present future research opportunities.

A common pre-season injury prevention assessment conducted by professional football clubs is the hamstring-to-quadriceps (H:Q) strength ratio calculated by peak torque (PT). However, it is debatable whether players that present low pre-season H:Q ratios are more susceptible to further sustaining in-season hamstring strain injuries (HSI). Based upon retrospective data from a Brazilian Serie A football squad, a particular season came to our attention as ten out of seventeen (~59%) professional male football players sustained HSI. Therefore, we examined the pre-season H:Q ratios of these players. H:Q conventional (CR) and functional (FR) ratios, and the respective knee extensor/flexor PT from the limbs of players further sustaining in-season HSI (injured players, IP) were compared to the proportional number of dominant/non-dominant limbs from uninjured players (UP) in the squad. FR and CR were ~18–22% lower (p < 0.01), whereas quadriceps concentric PT was ~25% greater for IP than UP (p = 0.002). Low scores of FR and CR were correlated (p < 0.01) with high levels of quadriceps concentric PT (r = −0.66 to −0.77). In conclusion, players who sustained in-season HSI had lower pre-season FR and CR compared to UP, which appears to be associated with higher levels of quadriceps concentric torque than hamstring concentric or eccentric torque.

“…In professional soccer, lower extremities are the most common body part prone to injury (84.1%) (Zouhal et al, 2021). Anterior cruciate ligament (ACL) sprains and rupture are the most frequent knee injury incurred during participation in sports and especially in football (Alizadeh et al, 2022).…”

Purpose: this study checks the effects of the reathletization protocol following anterior cruciate ligament (ACL) reconstruction in each of the anthropometric parameters, muscle strength and aerobic capacity. Material & Methods: we present a 12-weeks case-study account for an Algerian professional soccer player participated in this study (age: 21 years, height: 1.71 m, weight: 62.5 kg, body mass index: 21.37 and %body fat: 9.17%). Results: the authors have comparing the results recorded in measurements and tests before and after 12-weeks of reathletization protocol applied to the professional soccer player, which was intended. First: anthropometric parameters; weight increased by (+3.6 kg, +5.76%) and body mass index by (+1.23, +5.75%). % body fat had decreased by (-1.8 kg, – 19.62%). Their thigh perimeter at 10 and 15 cm from the patella had increased respectively ((injured side; at 10 cm (+4 cm, 9.75%) and at 15 cm (3cm, 6.83%)), ((healthy side; at 10 cm (+2.5 cm, 5.61%) and at 15 cm (2.5 cm, 5%)). Second: muscle strength tests increased in; Prone plank test (1.14 min, 52.77%). Countermovement jump (14.68 cm, 45.66%). Single-leg jump (healthy side; 0.57 cm, 39.04%), (healthy side; 0.1 cm, 4.76%) and Two legs jump increased by (0.43 cm, 22.63%). Third: aerobic capacity; intermittent fitness test increased in: IFT; (2.5 km/h, 14.28%) and maximal O2 consumption (5.65 mL/min/kg, 11.85%). Heart rate measurements decreased in maximum HR (10 bpm, 5.26%), and resting HR (10 bpm, 16.66%). Conclusions: after 12-weeks of reathletization protocol, the statistics values indicated a greater significant improvement in the performances of the soccer player. A study with larger population should be undertaken.
